After the Spring Festival, I found some of my mom's daily habits have changed. Her cooking way was different. Vegetables that had been cooked crisply became very tender and soft. Fish that had been fried became soup. Her old shredded potato turned into diced potato... Feeling strange, dad and I asked Mom the reason for the change. But all she said was, "Just trying a different taste". Then she was silent. But it wasn't just her cooking way. Mom also change other habits. After dinner, instead of watching films on TV as usual, she would put on her newly-bought sports clothes and asked Dad to go out for a walk. After they came back home, mom would lose herself in magazines or newspapers about healthcare. Mom almost never gets sick. Why was she suddenly interested in medicine? I couldn't understand her "abnormal" behavior. Then one day I came across her micro blog . "While visiting my parents during the Spring Festival, I suddenly realized that they are in their 70s now," my mom had written. "They move slowly and it is hard for them to do the housework. I should visit them more often... "Some cooking should be changed to keep them healthy. They like fish soup, diced potato, tender and soft vegetables... "I must also keep fit by doing physical exercise. If my parents are too weak to move around, I can be strong enough to take care of them. When I am old, my son can also pay less attention to taking care of me..." When I read this, I felt very sorry. I used to complain that Mom didn't understand me and couldn't give me everything I wanted. I always thought there was a wide gap between us. But now I completely understand her. How great she is! She always thinks of others before herself. Everything she does is to help the people she loves live better lives. How unselfish her love is! What does the writer want to show us readers by talking about this story?

As a young man, Tom was a famous artist with a wife and two fine sons. One night, his older son was ill. Tom and his wife thought it was nothing serious. But the boy died suddenly that night.. After his son died, Tom always felt very sad. To make matters worse, his wife also left him later, leaving him alone with his six-year-old younger son, Emie. Sadly, he turned to alcohol for help. As time went by, Tom began to lose everything he had---his land, house, etc. A few months later, Tom passed away alone in a small bar. Hearing of Tom's death, I thought,"What a complete failure!" But later, I began to change my earlier opinion. I knew Tom's now adult son, Emie. He is one of the kindest, most caring men. I saw the love between Emie and his children. And I thought that kindness and caring had to come from somewhere. One day, I asked him what made him become such a specia1 person. Emie said quietly, "My father came into my room every night, give me a kiss and said,"love you, son." Hearing his words, I understood everything. Tom didn't leave many things behind. But he had been a kind loving father, and left behind his best love. What happened to Tom's wife later?

I passed my driving test at the fourth attempt. You might think that means I'm not as safe as someone who passed on their first attempt. But would you feel safer with no driver at all? Maybe not, and that's why automotive firms have included driverassist functions in their driverless cars. This allows the human driver to take over if there is a problem. Google is one producer that has prototype driverless cars. These cars have been newly equipped with autosteering wheels and conventional controls to allow normal driving. But this is just a stage -- the vision is to have fully automated cars very soon. The director of Google's selfdrive project, Chris Urmson, hopes his 11yearold son will never have to take a driving test. To achieve that, the cars need to be on the roads in five years. He says driverless cars will greatly reduce accidents and traffic jams. According to Chris, about 1.2 million people are killed on the roads around the world each year. That number is equivalent to a jet falling out of the sky every day. He thinks gradual changes to existing car designs are not enough to deal with the problems. "If we are really going to make changes to our cities, get rid of parking lots, we need selfdrive cars," he says. Google's prototypes have covered over a million kilometers on the road. They have also had to deal with unexpected situations, such as a child driving a toy car in the road, and a woman in an electric wheelchair chasing a duck. In each case, the car reacted safely. Some are not convinced. Sven Beiker of Stanford University thinks driverless cars will still need human input in extreme circumstances. Chris Urmson mentioned his 11yearold son in order to show that _ .

To prevent diabetes you will get a real jolt ( shock ) when you follow the prescription offered up in the "Journal of the American Medical Association." This 'prestigious' organization reported on separate studies of coffee drinkers in Sweden and Finland. Whiz-bang medical researchers discovered that women could decrease their risk of diabetes by 29 percent when they followed a regimen of drinking three to four cups of coffee a day. The ladies who had the courage to drink 10 or more cups of coffee a day progressed even better. They reduced their risk of diabetes by 79 percent. The men participating in the studies also reduced their risk, but not to the extent as did the women. When men drank three to four cups a day, they reduced their risk of diabetes by 27 percent. The men who drank 10 or more cups of java per day reduced their risk by 55 percent. These results confirm a January report by the equally 'prestigious' Harvard School of Public Health. That report concluded that drinking six 8-ounce cups of coffee a day could reduce diabetes risk in men by about 50 percent and in women by 30 percent. If the numbers have any connection to reality, the more coffee you drink, the better off you are. And that is the rub. The numbers have nothing to do with reality, nothing to do with the truth. Here in America the rate of adult-onset diabetes, or Type 2 diabetes, is growing increasingly. Nowadays it typically shows up in middle-age populations, but the disease is on the rise among ever-younger age groups. Do not step up your coffee consumption in the belief it will help you prevent diabetes. This disease has ly nothing to do with a lack of coffee drinking. Science and truth are not synonymous. Medical scientists do not deal with truth. The medical scientists who monkey around with coffee drinking merely play with limited and approximate descriptions of reality. In this case, extremely limited and hardly approximate. If you are serious about preventing diabetes, you have to look at the differences between the people of the past who did not get diabetes and the people of today who get diabetes. _ involves more than merely harping on the fact the younger generation is becoming more overweight and less active. We have plenty of newly discovered diabetics who are active and on the thin side---and they drink lots of coffee. The primary difference between the people of the past who did not get sick and die like we do, and the present lot who become diabetics, is poor nutritional status. The diabetic-in-process has an inadequate intake of nutrients and/or excessive intake of nutrient-poor foods. Conversely , his/her healthy ancestors had a nutrient-rich diet. The nutrient-rich diet of the past contained, minimally, four times the amount of minerals, and ten times the amount of fat-soluble vitamins found in the American diet of the late 1930's and early 1940's. Folks who learn where health comes from and practice prevention won't become diabetic, and will not need the medical community dosing them with coffee, or any other magic bullet. What is the best title of the passage?

Swimming is one of those activities that can be learned early in life. Little children can learn to swim as soon as they walk. In fact, you need the same skills in walking as in swimming. However, I believe that five is the best age to learn. By five or six, a child knows fear of water, a very important thing to know. It's wise to be afraid, to recognize true danger. Young ones understand that the water can sometimes be very dangerous. To really benefit from swimming, every swimmer should learn, as soon as possible, these four basic strokes; butterfly, backstroke, Breaststroke, and crawl. I feel that one of these-the breaststroke-is different from the others, since some young swimmers use this stroke naturally, without any training. In swimming there are certain rules every swimmer should follow: 1). Never swim alone! No matter how good you are in the water, don't risk drowning by swimming alone. If you swim by yourself, with no life guards or friends with you, you may get into trouble. 2). Don't go beyond your abilities. Most swimmers know enough not to swim too far from the bank or the beach, Showing off by doing dangerous tricks is no good. Swim safely and you will continue to swim and alive. 3). Don't smoke. Swimming depends on a healthy body; good lungs are part of it. 4). Work at any activity that builds muscles. The author believes that fear of water is _ .

Scientists have created a " human-like robot" that can dance and do the housework. " Mahru" has been developed to imitate humans and can move its lips, eyebrows and pupils . The machine can also move its upper and lower body freely and automatically stop itself when walking. In addition, it has been programmed to give out two kinds of pleasant smells to match its emotions. The 1.5 tall robot was produced by researchers at the Korea Institute of Science and Technology (KIST) and is the first South Korean- developed machine of its kind. "'Mahru' will open the way for the commercial use of humanoid robots doing housework," You Bum-Jae, leader of the development research team ,said. "'Mahru' can dance while walking on its legs and is able to work in place of a human." Through an advanced motion capture system, "Mahru" can follow a variety of human movements and move its hands freely enough to deal with any obstacles that may get in its way when walking. State-funded KIST showed the robot during a presentation at its head office in Seoul. People here were treated to an entertaining demonstration which saw the robot show off the full range of its skills, most notably s series of dance moves. The research team added that they had designed another " Mahru", this time with sensors allowing it to distinguish between faces and objects. The showing of " Mahru" came a week after researcher in Japan said they had created the "most human-like" robot in the world. A team at robotics department of Osaka University in Japan claimed that " robogirl", Repliee R-1, " looks, moves and interacts like a human, and has silicone skin that feels almost human to the touch."

Being sociable looks like a good way to add years to your life. Relationships with family, friends, neighbours, even pets, will all do the trick, but the biggest longevity boost seems to come from marriage or an equivalent relationship. The effect was first noted in 1858 by William Farr, who wrote that widows and widowers were at a much higher risk of dying than their married peers. Studies since then suggest that marriage could add as much as seven years to a man's life and two to a woman's. The effect holds for all causes of death, whether illness, accident or self-harm. Even if the odds are stacked against you(the conditions are not favourable),marriage can more than compensate. Linda Waite of the University of Chicago has found that a married older man with heart disease can expect to live nearly four years longer than an unmarried man with a healthy heart. Likewise, a married man who smokes more than a pack a day is likely to live as long as a divorced man who doesn't smoke. There's a _ , however, as partners are more likely to become ill or die in the couple of years following their spouses; death, and caring for a spouse with mental disorder can leave you with some of the same severe problems. Even so, the odds favour marriage. In a 30-year study of more than 10,000 people, Nicholas Christakis of Harvard Medical School describes how all kinds of social networks have similar effects. So how does it work? The effects are complex, affected by socio-economic factors, health-service provision, emotional support and other more physiological mechanisms .For example, social contact can boost development of the brain and immune system, leading to better health and less chance of depression later in life. People in supportive relationships may handle stress better. Then there are the psychological benefits of a supportive partner. A life partner, children and good friends are all recommended if you aim to live to 100.The best social network is still being mapped out, but Christakis says:" People are interconnected, so their health is interconnected." William Farr's study and other studies show that _ .

Far from the land of Antarctica, a huge shelf of ice meets the ocean. At the underside of the shelf there lives a small fish, the Antarctic cod. For forty years scientists have been curious about that fish. How does it live where most fish would freeze to death? It must have some secret. The Antarctic is not a comfortable place to work and research has been slow. Now it seems we have an answer. Research was begun by cutting holes in the ice and catching the fish. Scientists studied the fish's blood and measured its freezing point. The fish were taken from seawater that had a temperature of -1.88degC and many tiny pieces of ice floating in it. The blood of the fish did not begin to freeze until its temperature was lowered to -2.05degC. That small difference is enough for the fish to live at the freezing temperature of the ice-salt mixture. The scientists' next research job was clear: Find out what in the fish's blood kept it from freezing. Their search led to some really strange thing made up of a protein never before seen in the blood of a fish. When _ was removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze quality and a lowered freezing point. Study showed that it is an unusual kind of protein. It has many small sugar molecules held in special positions within each big protein molecule. Because of its sugar content, it is called a glycoprotein. So it has come to be called the antifreeze fish glycoprotein. Or AFGP. What is the text mainly about?

Tobacco companies are fighting efforts in the United States and Australia to make their products less appealing. In Washington, a federal judge last week blocked the Food and Drug Administration from requiring new warning labels on cigarette packs. Judge Richard Leon ruled in a case brought by five tobacco companies. The judge temporarily stopped a new federal rule which requires large new warnings starting next September. These include color1 images such as a dead body or diseased lungs. And simple text warnings now appear. Congress called for color1 images showing the dangers of smoking, similar to what Canada does. But the tobacco companies say the new requirements approved in June violate their free speech rights guaranteed by the Constitution. Judge Leon said the FDA could not require the new labels before a lawsuit against the government is decided. Some experts say the process could take years. The judge said he believed the cigarette makers were highly likely to win their case. He said the images should be designed to appeal to emotions, rejecting government arguments that they should be purely factual. He accused the government of trying to use the labels to promote an "obvious anti-smoking agenda?" The head of an anti-smoking group, the Campaign for Tobacco-Free Kids, called the decision "wrong on the science and wrong on the law". About one-fifth of American adults smoke. The World Health Organization says tobacco kills nearly six mil-lion people worldwide each year. More than six hundred thousand of them are non-smokers who breathe other people's tobacco smoke. In Australia, tobacco companies want to stop what would be the world's most restrictive laws on cigarette advertising. Cigarettes could be sold only in plain olive-green packages. Only the brand name and health warnings could appear. The Senate passed the bill last week and sent it back to the Lower House to approve minor amendments . The law is to go into effect in December of next year. Tobacco companies Say the legislation violates the Australian constitution. They say it would unjustly reduce the value of their brand names and trademarks. Health Minister Nicola Roxon says the government is ready for a legal fight. What warning label on cigarette packs is being used in the United States?

The next generation telephone is called Superphone or personal Communication Network (PCN). Your superphone goes wherever you go, in your pocket. You can use it in the street, in an aeroplane, a boat, or a taxi; you can call from anywhere on the globe to anywhere else. Calls travel at the speed of light, via satellites using ultraviolet, high-frequency wave bands and each communication is automatically billed to your account. This new phone is the size and shape of a billfold . You unfold it to use it., making it long enough to reach from your ear to your mouth. There is a miniaturized touch pad, on which to enter the number you are calling. There is also a tiny liquid crystal screen on which you can read weather, news or financial reports. These news items are constantly updated by the company that sells the service. Letter keys on the touch pad also allow you to use this electronic marvel as a computer or word processor. You can plug it into your large home or office computer in order to transfer any data that you feed in during a business trip. The PCN also stores any useful information of your own that you might need as you travel, such as the names, addresses and phone numbers of several hundred people, important meetings, flight details and so on. When you need information, you simply call it up on the screen. You can even use your PCN to activate electronically controlled equipment at home. For example, you could switch your oven on or off, start the sprinkler system in your garden during a dry spell, get your video recorder to record a show on television, turn off the central heating, and so on. All of this from thousands of miles away, perhaps from the back of a camel in the desert. Prototypes are already being trialed. In spite of the complex technology, they will be cheap because of the enormous sales that will be made. The author's intention in mentioning "from the back...the desert" is to _

In recent years advances in medical technology have made it possible for people to live longer than in the past. New medicines and instruments are being developed every day to extend life. However,some people,including some doctors, are not in favour of these life extending measures,and they argue that people should have the right to die when they want. They say that the quality of life is as important as life itself,and that people should not be forced to go on living when conditions of life have become unbearable(.

The American Relay for Life is a life-changing event that gives everyone in communities across the globe a chance to celebrate the lives of people who have battled cancer, remember loved ones lost, and fight back against the disease. At Relay, teams of people camp out at a local high school, park, or an open place and take turns in walking or running around a track or path. Each team is asked to have a representative on the track at all times during the event. Because cancer never sleeps, it's an overnight event of up to 24 hours in length. History of Relay for Life: Relay began in 1985 when Dr. Klatt, a surgeon in Tacoma, Washington, ran and walked around a track for 24 hours to raise money for the American Cancer Society. Since then, Relay has grown from a single man's passion for fighting cancer into the world's largest movement to end the disease. Each year, more than 3.5 million people in 5,000 communities in the United States, along with additional communities in 19 other countries, gather to take part in this global event and raise much-needed funds and awareness to save lives from cancer. Requirements for Relay for Life: Anyone can participate in Relay for Life. Friends, families, neighbors, classmates, sports teams, etc., can form their own teams. No matter who you are, there's a place for you at Relay. The only requirement to participate in Relay for Life is the $10 registration/commitment fee per person. After that, anything you can raise through individual, team, or online fundraising is accepted. It is recommended that each participant sets a personal goal to raise $100. If you raise more, that's even better. Even if you do not raise $100, you are still welcome to participate. If you want to be part of Relay, you can start a team or join an existing team online. You can also make an online donation. By supporting Relay, you help the American Cancer Society save lives, and that helps us move closer to our ultimate goal of a world with less cancer and more birthdays. Online Help: Please check our Online Help&FAQ page for answers to commonly asked questions about online fundraising and about Bark For Life. Local Help: If you have questions that are not answered by the Online Help&FAQ page, or if you would like assistance from your local event representative, feel free to contact Jill Tetherow at (402) 310-2498, or [email protected].

The Human Genome Project, a great $3 billion, 15-year task aimed at drawing the genetic map of humans, is now more than 90 percent completed. The scientific and medical communities are very excited about the chances genetic research provides for getting rid of diseases and prolonging human life. But those communities and policy makers are also careful about the scientific door they are opening as the project uncovers the mysteries of life. For the last few years, the genetic advances in the fast developing field of biotechnology have provided material for all kinds of work, but the developments of modern science in unlocking the secrets of human genetic code have opened a world of possibilities for human health, as well as for the population imagination. While European and Japanese researchers are making rapid progress in decoding human DNA, the leading organization for genetic research in the Untied States, which began in 1990, is "unlocking the code" of the human body to learn how to defeat fatal diseases. Already, the Human Genome Project has become widely known and praised for finding the genes connected with as yet terrible diseases, and making progress toward separating the genes that show a sign of breast cancer or AIDS. Once these genes are found and studied, researchers can develop new ways to attack infections, and genetic diseases. Medical companies are very interested in mapping the human genome, as they expect to develop a lot of new drugs for these illnesses. According to the passage, which of the following is NOT true?

We must do what we can to protect the plants because plants are very important for living things. Life could not go on if there were no plants. This is because plants can make food from air, water and sunlight. Animals and man cannot make food from air, water and sunlight. Animals get their food by eating plants and other animals. Therefore animals and man need plants in order to live. This is why we find that there are so many plants around us. If you look carefully at the plants around you, you will find that there are two kinds of plants: flowering plants and non-flowering plants. Flowering plants can make seeds. The seeds are _ by the fruits. Some fruits have one seed, some have two, three or four, and some have many seeds. But a few fruits have no seeds at all. An example of a fruit without seeds is the banana fruit. Most non-flowering plants do not grow from seeds. They grow from spores . Spores are very small. Some spores are so small and light that they can float in the air. We may say that spores are quite the same as seeds. When these spores are all on wet and shady places, they usually grow into new plants. What can we infer from the passage?

Every living thing on Earth is either a plant or an animal, right? Wrong! Many organisms in our world are neither. Some of them float through the air, and some lie hidden in the ground. They do not need sunlight to survive, and if the weather becomes too cold, they can become inactive until conditions improve. What are these? They are called fungi , and you see them almost every day. Many kinds of fungi seem _ , such as the green black things that appear on the food which are left too long in the refrigerator. But other kinds are not so bad. For example, the yeast that is used to make bread and mushrooms are both fungi. What makes fungi different from plants and animals? An animal can move around by itself. Fungi get around too, but they don't have feet, wings, or tails. They have to wait for wind or some other outside force to move them. Plants are different from fungi because they have chlorophyll . It helps them make food from the energy in sunlight. Fungi do not have chlorophyll. Some fungi are bad, while others are not. Some fungi cause diseases, such as athlete's foot, which makes feet uncomfortable. Other kinds of fungi can be used to make medicines, which have saved many lives. Fungi clean up more than wounds, though. They are the world's first recyclers. Without fungi, our world would be a mess. Since fungi cannot make their own food as plants do, they must get their food elsewhere. Many fungi get their food from dead plants. They break them down and turn them into soil. The fungi get a meal, and the world gets a housecleaning. According to the passage, _ .

Picture a wasteland of old computer monitors and TVs, stretching as far as the eye can see. Imagine towers of boxes, all of them filled with broken glass and discarded electronic devices. Technology graveyards like this can be found in communities across the country. Experts say that landfills and warehouses will overflow unless a plan for the disposal and reuse of electronics is put into place . "We can't put electronics and glass aside and tell ourselves we'll deal with them later ," Lauren Roman , managing director of Transparent Planet said. Roman's group works to improve the disposal of electronic waste. She says about 660 million pounds of tech-trash is produced each year in the U.S. What's behind the tech trash pile-up ?About ten years ago ,major advances were made in computer and television technology . Manufacturers began producing devices like flat -paneled LCDs and plasma screen monitors. These new products provide a clearer image and take up less space than older models. It goes without saying that consumers choose them rather than heavy glass-based technologies. The new electronics are built with materials that are difficult to recycle. In addition, the new products have decreased the demand for recycled parts from the older monitors and screens. Older, heavier computer monitors and TVs used glass-based components called CRTs. CRTs have a high lead content and can be environmentally hazardous if not recycled properly . If crushed and put in landfills, the lead from CUTs could seep into groundwater and rivers, harming the water supply. For many years, plants and recycling programs safely processed CRTs. The recycled CRTs were reused in the construction of new monitors. Monitors being made today do not use glass tubes . "People are returning old -style TVs with CRTs , but no new ones are being made ," said Linnell. This is creating an imbalance in the amount of glass being disposed of and recycled properly. Many recycling companies have shut down. Others no longer have the resources or space to process these materials. This results in stockpiling. However , experts say there are ways to safely and responsibly address the tech-trash problem. What is the main idea of the passage?

Writing one or two articles a day is a fair goal for a human writer. By contrast, the Wordsmith platform can produce up to 2,000 articles a second! Wordsmith is one example of natural language-generation software, often referred to as a robot journalist. To be fair, the software doesn't start from the beginning, like a human writer might. Instead, the software takes a set of structured data and transforms it into readable text. Natural language-generation software, such as Wordsmith and Quill, does its work by identifying trends and highlights in sets of data. The software then searches its own dictionary for the words to express its findings.[:] Why keep human writers around Although this type of software writes faster than any human, it requires sets of structured data to work. That's why it's especially useful for writing earnings reports and other types of "dry" writing. Humans, on the other hand, are good at turning their unstructured thoughts directly into prose. The reports produced by Wordsmith and Quill read naturally, and they can match the tone of human writers. But for now, the robot journalists probably won't steal many jobs or win any Pulitzer Prizes! Current applications of natural language-generation software Financial reports: The software is commonly used by banks or traders to analyze large amounts of financial data and then produce reports in plain English. Health and fitness: The software can turn data gathered from wearable devices or fitness trackers into personalized reports. The writing tone can even be adjusted to sound more encouraging! Sports reporting: The software is often used to turn real baseball, basketball and football statistics into exciting stories. What does natural Language-generation software refer to?

The oldest and most common source of renewaBle energy known to man, Biomass is one of the most important forms energy production in the United States and elsewhere. Since such a wide variety of Biomass materials is everywhere ---- from trees and grasses to agricultural and city ---- life wastes ----Biomass promises to play a continuing role in providing power and heat for millions of people around the world. According to the Union of Concerned Scientists(UCS), Biomass is a kind of renewaBle energy source that produces no carBon dioxide , Because the energy it contains comes from the sun. When plant matter is Burned, it gives off the sun's energy. In this way, Biomass serves as a sort of natural Battery for storing the sun's energy. As long as Biomass is produced continuously ----with only as much grown as is used--- the "Battery" lasts forever. According to the Energy Information Administration, Biomass has Been one of the leading renewaBle energy sources in the United States for several years running through 2007, making up Between 0.5 and 0.9 percent of the nation's total electricity supply. In 2008----although the numBers aren't all in yet----wind power proBaBly took over first place Because of the rapid development of wind farms across the country. Producing power from Biomass helps reduce some 11 million tons of carBon dioxide each year. Some homeowners also try to make their own heat By using Biomass materials. Such practice may save homeowner's money, But it also produces a lot of pollution. So, the Best way is to encourage power plants to use it. Where does the text proBaBly come from?

She took up skating at age 85, made her first movie appearance at age 114, and held a concert in the neighborhood on her 121st birthday. When it comes to long life, Jeanne Calment is the world's recordholder. She lived to the ripe old age of 122. So is 122 the upper limit to the human life span ? If scientists come up with some sort of pill or diet that would slow aging, could we possibly make it to 150-or beyond? Researchers don't entirely agree on the answers. "Calment lived to 122, so it wouldn't surprise me if someone alive today reaches 130 or 135, "says Jerry Shay at the University of Texas. Steve Austad at the University of Texas agrees. "People can live much longer than we think, "he says. "Experts used to say that humans couldn't live past 110. When Calment blew past that age, they raised the number to 120. So why can't we go higher? " The trouble with guessing how old people can live to be is that it's all just guessing. "Anyone can make up a number, "says Rich Miller at the University of Michigan. "Usually the scientist who picks the highest number gets his name in Time magazine. " Won't new anti-aging techniques keep us alive for centuries? Any cure, says Miller, for aging would probably keep most of us kicking until about 120. Researchers are working on treatments that lengthen the life span of mice by 50 percent at most. So, if the average human life span is about 80 years, says Miller, "adding another 50 percent would get you to 120. " So what can we conclude from this little disagreement among the researchers? That life span is flexible , but there is a limit, says George Martin of the University of Washington. "We can get flies to live 50 percent longer, "he says. "But a fly's never going to live 150 years. "Of course, if you became a new species , one that ages at a slower speed, that would be a different story, he adds. Does Martin really believe that humans could evolve their way to longer life? "It's pretty cool to think about, "he says with a smile. Who would agree that a scientist will become famous if he makes the wildest guess at longevity?

It has always been said that women are not good drivers, because they simply don't have very good driving ability. On the other hand, most car accidents happen to men; very few happen to women. From this, we can see that women are much more careful while driving. Another very interesting fact that we should point out is that in the past, women preferred to let their husbands be the only driver in the family rather than have a driving license. Somehow they were prevented from making this step in their lives, but nowadays there are many women that want to pass their driving tests from an early age. However, we have to admit that men are more skillful drivers than women, but this does not mean that a woman cannot become a good driver by accumulating experience. So more and more teenagers and women around the age of thirty now want to pass their driving tests. While taking their driving lessons, they also have a number of special lessons with their parents or somebody in the family that has a driving license, this is just to improve their driving abilities and help them to pass the tests more easily. To conclude, we can say that women are not such bad drivers. They just need more experience than men in order to be able to drive well. And on the other hand, there are a number of women that show better driving skills than the men around them. Compared with the past, nowadays many women _ .

On the second day of the World Internet Conference themed with cybersecurity and international cooperation held in Wuzhen, an official with China's network emergency watchdog said that 6,118 domestic websites have been controlled by the United States, according to Shanghai Securities News. Among the hacked websites in the first half of this year, 48.8 percent were under the thumb of overseas IP addresses, said Huang Chengqing, director-general of the National Computer Network Emergency Response Technical Team and Coordination Center (CNERT/CC). He added that the US contributed the most, followed by Hong Kong, which controlled 3,097, and South Korea with 2,307. Among the overseas IP addresses inserting backdoor programs in domestic websites, the US accounted for 29.3 percent, South Korea for 6 percent and Hong Kong for 5 percent, he said. In addition, 4.9 percent of government websites have been attacked, and 3.2 percent inserted with backdoor programs. Huang also said that the number of Chinese computers affected by Trojan Horse viruses reached 190,000 in the six-month period. To safeguard cybersecurity, the CNERT/CC has cooperated with the Association of Southeast Asian Nations, and built relationships with 59 countries and 127 organizations. Over the past two years, the center dealt with more than 15,000 cross-border online security cases. The theme of the World Internet Conference is _ .

At times my mom has been uncomfortable seeing these qualities in me. For example,when I was 12,I went to Puerto Rico all by myself to stay with my grandmother for the summer. My mom was extremely nervous about it. She kept telling me how things were different in Puerto Rico,to always put on sunscreen,not to wander away from my grandmother,and other warnings. She helped me pack and did not leave the airport until she saw my plane take off. But despite her worries,she let me go on my own. As I moved into my teens,she continued to give me space to grow and learn,even when it might have been difficult for her. When I reached my senior year,I decided to move away for college. Once again I found that I differed from my peers:While many of them wanted to stay close to home,I couldn't wait to be out in the world on my own. While my mom may not have been happy at the thought of my going away,she was supportive and excited for me. One big thing I realized during my senior year,as my mom granted me more freedom,was that she actually believes in me and trusts me. That means a lot. Most of my life,and especially when I was little,the main person I tried to impress in my schoolwork or other things was my mother. I knew she expected nothing but the best from me. Sometimes it was hard to live up to her standards;getting a single B on my report card would make me feel bad because I knew she wanted me to have all A's. I know that her high standards have helped me stay focused on what's important,like education,and made me who I am. I am thankful for her support and involvement in my life .Most of all I respect her. She is the strongest woman I know and that's why I have turned out so strong and independent.

Mobile phones and the internet have improved our live in many ways. However, along with improvements, they have also brought a number of worrying problems. Many car accident are caused by mobile phones. You can use many new mobile phones to get on the internet. This can be very convenient, but some drivers get on the internet while driving. Driving needs all our attention. By looking at their mobile phones and not at the road, these insensitive Drivers are a danger to us all. Many of the dangers of the internet are well known. Children who visit websites without their parents' permission sometimes talk to older people they don't know and put themselves in great danger. People with blogs sometimes post embarrassing photographs of people they don't know on their websites without permission. There are also people who use the internet to get personal information that we do not want them to have. Mobile Phone and Internet Safety Tips If you need to use a mobile phone with you drive use a "hands-free" phone. In difficult driving situations such as rain or snow, do not use your phone at all. Do not make very important phone calls while driving. They take your attention off the road. Tell your children not to talk with anyone they do not know on the internet. In an embarrassing situation, pay attention to people around you. People will be shy about taking your picture if they know you're paying attention. Refuse to give out any information personal information on the internet. Which of these dangers of mobile phones or the Internet is Not mentioned in the passage?

There are plenty of reasons that have put sea turtles in danger. Here are some. The sea turtles tend to live in water, but the females come over to lands for nesting. This is the time when they are in the most vulnerable position. Their nesting areas have been taken over by human settlements and recreation development. This has forced them to search for areas that are less suitable for nesting. The egg is the first step for a sea turtle to have a chance of life. And this first step of life has become vulnerable in many countries. The sea turtles have no way to protect their eggs. As a result, the poachers have an opportunity to steal their eggs. The sea turtles are caught in shrimping vessels that use nets. The nets can drown these poor creatures. They die, as the nets are not pulled out fast. Gill nets and drilling for oil also _ habitat destruction and injury to the animal. One female sea turtle can lay hundreds of eggs in one nesting season. These eggs are preyed on by crabs , foxes, birds, and humans, as they make their run towards the sea. By the time they reach the shallow water, half of them have been removed by their predators on land and some are eaten up by fish in water. Only a few lucky ones win the battle of survival and live past their 1st birthday! The sea turtles take more than a decade to reach maturity. Then they start breeding and adult turtles have to live for many years to maintain the balance of population. However, as mentioned above, the adults face a lot of hardships for surviving. Pollution, long lines of fishing fleets, high seas, and even tumors, etc., all cause death of these massive, beautiful species. When sea turtles are nesting, probably _ .

Body language shows all kinds of feelings and is sometimes more important than spoken language.A smile is a usual facial expression----it shows that you are friendly to others. However, it does not always mean that you are happy. A smile can hide other feelings, like anger, fear, or worry. In most countries, nodding the head up and down shows agreement, while shaking the head means that you do not agree, or that you would not like to do something. If you stand holding your arms across your chest, you may be protecting yourself---just from a conversation you do not want! If you sit looking at the person you are talking to and then turn toward to him, it shows that you are interested. If you roll your eyes and turn your head away, most likely you do not believe what you are hearing, or you do not like what you hear. Body language shows _ .

Can you imagine being savagely attacked by a dog? What if the attack was so severe that your nose, lips and chin were completely destroyed? How would you feel about yourself? Would you be able to look at yourself in the mirror? And how do you think other people would treat you? Isabelle Dinoire is someone who can answer all of these questions honestly and openly. Last November Isabelle was attacked and mauled by her own dog. The attack was so severe that her lower face was damaged; it seemed, almost beyond repair. She was rushed to hospital and became the first person ever to have a face transplant. With such severe injuries doctors offered Isabelle little hope that they would be able to repair the damage to her face using conventional surgery. Shortly after being admitted, she came to the attention of Dr Bernard Devauchelle who, unlike other surgeons, believed there was an alternative: "We found ourselves saying, yes, it's clear this woman needs a transplant," he said. Two days after the operation she saw her face in the mirror for the first time. She said "I was scared to look at myself, but when I did it was already marvelous and I couldn't believe it. I thought it would be blue and swollen but it was already beautiful." Now, less than a year after her 15 hour operation, she's trying to rebuild her life and there is no doubt how she feels about her new face: "I have been saved. Lots of people write saying that I need to go on, that it's wonderful. It's a miracle somehow." Although there were ethical questions raised about their decision to carry out the procedure, the doctors who operated on Isabelle are quick to defend their decision. One of them said "Was it possible for her to live without a face? It's easy to say we shouldn't have done the operation, but her life has changed, she goes shopping, goes on holiday, she lives again." What would be the best title of the passage?

A young father was visiting an old neighbor. They were standing in the old man's garden,and talking about children. The young man said,"How strict should parents be with their children?" The old man pointed to a string between a big strong tree and a thin young one."Please untie that string," he said.The young man untied it,and the young tree bent over to one side. "Now tie it again,please," said the old man,"but first pull the string tight so that the young tree is straight again." The young man did so.Then the old man said,"There,it is the same with children.You must be strict with them,but sometimes you must untie the string to know how they are getting on. If they are not yet able to stand alone,you must tie the string tight again.But when you find that they are ready to stand alone,you can take the string away." The young man untied the string _ .

Short people, studies have shown , are more likely to have a stroke , suffer from high blood pressures and heart disease and be bullied in school . Now, researchers report that short people--at least in the past--were also more likely to die at a younger age than their taller peers. Their study, published in the Journal of Epidemiology and Community Health , found that short bones have something to do with short life for more than 1,000 years. The conclusion was based on 490 sets of adult skeletal remains from an archaeological site in northeastern England , YC dating from the 9th century to about 1850 . About 55% of men and 73% of women died before the age of 45, and 39% of men and 56% of women died before age 30. The risk of death before age 30 declined as bone length increased. "This study provides evidence from an archaeological sample that long bone length is connected with age at death--those with smaller bones tend to die younger," according to Dr. D.J. Gunnell of the university of Bristol in the UK and colleagues . While it is not clear why short stature might be linked to earlier death , the researchers point out that height is _ of childhood nutrition, which may have long-lasting effect on health . "Mechanism for height-mortality associations in the past may differ from those today , for example , short stature may have increased the risk of death in childbirth and this may explain the higher risk of premature mortality in women," Gunnell and colleagues write . "However, short bones, it would appear, have always been a marker of a short life," the authors conclude. The title of the passage should be _ .

On May 2, 2012, Ashok Gadgil became the winner of the $100,000 Lemelson-MIT Award for Global Innovation . Each year, the honor is given to an inventor who has made a big difference in the lives of people in developing countries. Gadgil is a professor and physicist at the University of California, Berkeley. He spent thirty years helping people in need. His inventions have helped more than 100 million people around the world. "I chose to focus on problems where my knowledge of science could help," Gadgil said. In the 1990s, Gadgil designed his first life-saving invention after more than 10,000 people died from Bengal cholera because of the clean water crisis in India. His invention uses ultraviolet light to kill deadly disease-carrying germs from drinking water. It costs just one cent to clean five liters of water (about 21 cups). So far, the invention has provided safe drinking water for more than five million people in India and other developing countries. Gadgil's another important invention is the Berkeley-Darfur Stove . The long and violent war in Darfur, Sudan, has caused many people to move to foreign countries and live in refugee camps . They are given food aid. But people still have to travel a long distance five times a week to gather firewood to cook meals. This can be dangerous because of street violence in the area. To avoid danger, some spend much of their money used to feed their families buying firewood. The stove Gadgil created cuts fuel usage by 55%. That means people wouldn't have to leave the camps to find firewood as often. The invention also helps to save homes more than $300 a year. About 125,000 people and their families have been helped. As a professor, Gadgil encourages his students, "Be optimistic when you try a hard problem," he says. "It's when you solve a large problem that you can have a big influence on the world." Which of the following statements about Gadgil is TRUE?

Nowadays, there is a heated debate on whether pollutants should be cleaned in the air. Cleaning up the air, while good for our lungs, could make global warming worse. And the pollutants still go up around the air, along with carbon dioxide. These pollutants are called aerosols and they include soot as well as mixtures of nitrogen and sulfur and other stuff into the air. Natalie Mahowald, a climate researcher at Cornell University, says so far, scientists have mostly tried to understand what those aerosols do while they're actually in the air. "There are so many different kinds of aerosols," she says. "Some warm and some cool. But in fact, humans are giving out a lot of extra aerosols, and they tend to cool for the most part." The aerosols reflect sunlight back into space, or keep us cool. But it turns out that's not all they do. These aerosols also influence how much carbon dioxide gets drawn out of the air by plants on land and in the sea. "They can add nutrients, for example, to the oceans or to the land," Mahowald says. "But also while they're in the atmosphere they can change the climate, and thus that also can influence the amount of carbon, the land or the ocean can take up. So there are quite a few different ways that aerosols can act on each other." Mahowald's results suggest that reducing those pollutants could be an even bigger problem than realized, when you consider that aerosols help remove carbon dioxide from the air by encouraging plant growth. Hard numbers on this effect are highly uncertain at the moment, but this could turn out to be quite significant. And studying it is not easy because the effects aren't well understood. For example, nitrogen can be a fertilizer , but it can stop plant growing when nitrogen comes out of the air in acid form. Right now it seems like we're much more likely to clean up aerosol pollution, while increasing the amount of carbon dioxide in the air. So scientists, unfortunately, may have a chance to see whether this experiment on our planet should continue or not. Which of the following can be the best title of this passage?

A friend is better than fortune. A friend is worse than poison in some cases. The two sentences above have opposite meanings and seem to be unreasonable, but they can be explained as follows: the first refers to all good friends who drive us towards good while the second all bad ones who lead us into bad ways. My ideal friend is of course a good friend whose goodness is shown below -- he has no bad habits, such as smoking and drinking. He lives in frugality . He studies hard so as not to waste his golden time. At home he honors his parents and loves his brothers; at school he respects his teachers and shares the feelings of his classmates. He treats those truly who are true to him. In a word, he has all the good characteristics that I don't have. I can follow him as a model. With his help I can be free from all difficulties.

Do you forget to turn off the lights and heaters when you go out of a room? In 2040 it will not matter. They will turn themselves off--and on again when you return. You will choose the temperature for each room, the lighting and the humidity. A sensor will find the presence of a human (and, with luck, ignore the dog!) and turn the systems on, and when the humans leave it will turn them off again. The sensors will work through the central home computer, and they will do much more than just turn the fires and lights on and off for you. They will find faulty electrical appliances, plugs or switches, separate them so that they cannot harm anyone, and then warn you that they need repair. They will detect fire and if you are out of the house, the computer will call the fire brigade. It will not be too difficult because the locks on the outside doors will be electronic. You will open them using your personal card--the one you use for shopping--maybe using a number known only to you. It will be impossible to lose the key, and a housebreaker will have to tamper with the lock or with a window. It is not very difficult to make such tampering send a signal to the computer. The computer will be more than a fireman-policeman-servant. It will be an entertainer, and most of your entertainment will come right into your home. It does now, of course, but by 2040 "entertainment" will mean much more. For one thing, you will be able to take part actively, rather than just watching.

Scientists from England's Newcastle University have discovered that bacteria have the ability to detect smells, according to a study by the university on Sunday. The team of scientists, led by Dr. Reindert Nijland, discovered that bacteria can detect certain types of smell- producing chemicals, including ammonia that is produced by other bacteria. Once they sense the smells from other kinds of bacteria, the bacteria will gather together to form a colony and form a layer of slime in order to force the competitors out of their area. The response decreases as the distance between the two bacterial colonies increases. That slime, also known as biofilm, is one of the primary causes of infection on many medical implants . Biofilms also slow down ships and are believed to cost the marine industry millions of dollars annually. However, they can also be used to clean up spilled oil floating on the sea, as they grow strong on it. "This is the first evidence of a bacterial 'nose'able to detect potential competitors," Dr. Nijland said in the August 15 statement, which confirms that bacteria possess qualities similar to four of the five senses that humans enjoy (sight, hearing, touch, taste, and smell), the others being touch, taste, and sight. "The fact that bacteria formed slime when exposed to ammonia has important significance for understanding how biofilms are formed and how we might be able to use them to our advantage," he added.

Dear David, I'm glad you would like to share your feelings with me.It's hardly surprising that your feelings of not being "grown up" have come on strongly at this point in your life,just before you're about to become a father.You are asking:will I make a good father?How will I cope? Should I have brought another little person into the world? Can l provide for it? Help! I think nearly every sensitive about-to-be-parent must have these occasional feelings of self-doubt and inadequacy before the birth and it would be most unusual if you didn't share them.It's difficult,honestly,to feel grown-up unless you have something less grown-up to relate to. The boss with a hen-pecking wife may feel like a seven-year-old when he's at home.But as he walks through the office door,and knows he's going to be surrounded by staff looking to him for Advice,he grows into a fully mature man.And I think it's a mistake to imagine that we all feel,as we age,a kind of progression of states,from the baby to the adult.Most people feel,on Tuesday,about three years old,and on a Wednesday,around 80. There's a common remark that "all men are little boys",but it's not true.It's more true that men often behave like little boys.But nearly all people,at some moments in their lives,are capable of groat maturity. Once your baby arrives,you'll soon feel less childlike,or rather,less often.When your child tries to put its fingers into the electric plug,the adult in you will rise up to prevent it.You'll see you have very little in common with a needy child,particularly if it's looking to you for comfort and support. Comfort yourself,David,with two truths.One is that your friends laugh when they talk about this subject because they,like you,feel frightened.And remember that people who haven't grown up don't go around talking about the fact that they don't feel grown-up. Hope my advice will be helpful and good luck to you and your little one. Yours sincerely Miss Advice Miss Advice wrote the letter to _

Have you ever run into a careless cell phone user on the street? Perhaps they were busy talking, testing or checking updates on WeChat without looking at what was going on around them. As the number of this new "species" of human has kept rising, they have been given a new name -- phubbers . Recently, a cartoon created by students from China Central Academy of Fine Arts put this group of people under the spotlight. In the short film, phubbers with various social identities bury themselves in their phones. A doctor plays with his cell phone while letting his patient die, a pretty woman takes selfie in front of a car accident siteand a father loses his child without knowing about it while using his mobile phone. A chain of similar events eventually leads to the destruction of the world. Although the ending sounds overstated, the damage phubbing can bring is real. Your health is the first to bear the effect and result of it. "Constantly bending your head to check your cell phone could damage your neck," Guangming Daily quoted doctors as saying. "The neck is like a rope that breaks after long-term stretching." Also, staring at cell phones for long periods of time will damage your eyesight gradually, according to the report. But that's not all. Being a phubber could also damage your social skills and drive you away from your friends and family. At reunions with family or friends, many people tend to stick to their cell phones while others are chatting happily with each other and this creates a strange atmosphere, Qilu Evening News reported. It can also cost you your life. There have been lots of reports on phubbers who fell to their death, suffered accidents, and were robbed of their cell phones in broad daylight. What may the passage talk about next?

When Albert Einstein was young, he was a quiet child who spent much of his time alone. He was slow to talk and had difficulty in learning to read. When Albert was five years old, his father gave him a compass. Albert was filled with wonder when he discovered that the compass needle always pointed in the same direction ---- the north. He asked his father and his uncle what caused the needle to move. Their answers were difficult for Albert to understand. Yet he spent a lot of time thinking about them. He said later that he felt something must be hidden behind things. Albert didn't like school. The German schools of that time were not pleasant. Students couldn't ask questions. Albert said he felt as if he were in prison.. One day Albert told his uncle Jacob how much he hated school, especially mathematics. His uncle told him to solve mathematical problems by pretending to be a policeman. "You are looking for someone," he said, "but you don't know who he is. Call him X. Find him by using your mathematical tools." Albert learned to love mathematics. He was studying the _ mathematics of calculus while all his friends were still studying simple mathematics. Instead of playing with his friends he thought about things such as "What would happen if people could travel at the speed of his light?" Albert wanted to teach mathematics and physics. He graduated with honors, but it was a pity that he could not get a teaching job. We can learn from the passage that _ .

Head held high, hands firmly gripping her walker, Mary Arnott, 99, walks slowly with dignity through the women's changing room at the Etobicoke Olympium pool, past the teenage girls who have been blow-drying their hair for half an hour, into the mist of the showers, then out the door and first one into the heated pool. She jumps over to the shallow end, stopping to talk to friends--everyone knows Arnott here; she swims twice a week and treats it as a job--about their children, the viciousness of bridge and their health. In fact, Arnott is an exception to the exception. Not only has she lived 20 years past the average lifespan for Canadians, she's healthy, her mind is sharp and she lives independently. Born in Brooklyn on May 28, 1909, Arnott was raised on Staten Island. She survived scarlet fever , helped bring up four siblings after her mother died in 1923 and worked as a secretary in New York City for 12 years, earning$35 a week and a$150 bonus at Christmas. Now she's happy living in a one-room apartment with a kitchen and a bathroom in her daughter's house. She wears a hearing aid, does the cryptic crossword with a magnifying glass, and can't really explain why she has live so well so long. Until recently, she has still liked to drink red wine--she used to drink two glasses before supper each day. It's more likely genes, she admits. Her interest in other people and life in general may have had something to do with it. Asked if a star photographer can take her picture at the pool, Arnott seems cheerful.

Dogs can be worried and pessimistic just like people, researchers report in a new study in Current Biology. And they aren't talking about basset hounds : those dogs just look as if they expect the worst. What the scientists say is that dogs that exhibit anxiety when left home alone by their owners may have bigger problems -- they may be in a permanent bad mood. This pessimistic outlook may not otherwise be easily apparent in a dog's other characteristics, like running speed or learning ability, the study reports. Dogs are similar to humans in the role that emotional state plays in decision making, said Michael Mendel, a veterinary scientist at the University of Bristol and the study's lead author. The study's researchers looked at 24 dogs in shelters in Britain. They placed the dogs in isolated settings and observed their reactions -- many barked, jumped on furniture and scratched at the door. Then they placed bowls in two rooms. One bowl contained food, while another was empty. After training the dogs to understand that bowls can sometimes be empty, and sometimes full, they began to place bowls in ambiguous locations. Dogs that quickly raced to the locations were more optimistic, and in search of food. Those that did not were deemed pessimistic. The more separation anxiety a dog expressed while in isolation, the more likely the dog was to have a pessimistic reaction, the researchers found. The study carries an important message for dog owners, Dr. Mendel said. Dogs that express serious anxiety when alone may need treatment, as it could be a sign of unhappiness and instability. According to Dr. Mendel, which statement is true?

For well over a thousand years, smallpox was a disease that everyone feared. The disease killed much of the native population in South America when the Spanish arrived there in the early sixteenth century. By the end of the eighteenth century, smallpox was responsible for about one in ten deaths around the world. Those who survived the disease were left with ugly scars on their skin. It had long been well known among farmers that people who worked with cows seldom caught smallpox; instead, they often caught a similar but much milder disease called cowpox . A British doctor called Jenner was extremely interested in this, and so he studied cowpox. He believed that, by vaccinating people with the disease, he could protect them against the much worse disease smallpox. In 1796, he vaccinated a boy with cowpox and, two months later, with smallpox. The boy did not get smallpox. In the next two years, Jenner vaccinated several children in the same way, and none of them got the disease. News of the success of Jenner's work soon spread. Vaccination soon became a common method to protect people against other diseases caused by virus, such as rabies , and vaccines were sent across the world to the United States and India. It took nearly two centuries to achieve Jenner's dream of getting free of smallpox from the whole world. In 1967, the world Health Organization (WHO) started a great vaccination program, and the last known case of smallpox was recorded in Somalia in 1977. The story of vaccinations does not end there, however. There are many other diseases that kill more and more people every year. Besides, many new diseases are being discovered. The challenge for medical researchers will, therefore, probably continue for several more centuries Edward Jenner discovered that vaccination with cowpox could _ .

Schools have been blamed for giving kids access to soda in vending machines . But new data suggest that school soft drink sales may not be an important factor in how much soda kids drink. In the current issue of The Journal of Nutrition Education and Behavior, researchers compared soda consumption among nearly 500 students inprefix = st1 /Mainewho attended seven schools over two school years. Four of the schools cut back on soft drink availability at the schools, while three of the schools made no changes. All the students were drinking less soda by the end of the study period, but there were no meaningful differences in overall soft drink consumption among the different schools. The data suggest that limiting soft drink availability at school doesn't result in meaningful changes in drink consumption patterns. While there were no changes in overall soda consumption, there was a notable shift in diet soda drinking among girls. If the school cut back on soda availability, girls were less likely to drink diet soda, compared to girls in schools that made no changes. The data are the latest to suggest that schools may not play as big of a role in kids' poor eating habits as widely believed. Last year, The American Journal of Public Healthpublished a provocative study showing that childhood weight problems often get worse in the summer, when kids are out of school. Data from kindergarteners and first graders found that body mass index increased two to three times as fast in summer as during the regular school year. Minority children were especially at risk, as were children who were already overweight. Even children who were too thin and needed to gain weight appeared to have better eating habits during the school year. They actually gained more weight while in school and less in the summer. Even so, much of the focus on childhood nutrition and obesity remains in the nation's schools. Today, The Timesreported that even the school bake sale is disappearing as districts impose strict standards on the food served on school grounds. Better eating habits may be best developed _ .

Sometimes successful health campaigns can have quite unexpected reactions. The years of warnings about skin cancer mean that Britons are happy to cover themselves in sunscreen or stay out of the sun altogether, but it also means that most of us are not getting enough vitamin D. Scientists announced yesterday that Britons need to increase to three times the amount of vitamin D they get per day. They called on food producers to fortify their products with more of the vitamin and suggested people should consider taking supplements to keep levels up. They also suggested getting out in the sun for short periods more often, but they warned against "sun bingeing". The government does not publish official advice on the amount of vitamin D people should take due to a lack of research, says Dr Birgit Teucher of the Institute for Food Research. But in the US, the government recommends 5 micrograms a day. By that count, Dr Birgit Teucher said that around 90% of Britons between 19 and 64 would be lacking in the vitamin because they only took around 3 micrograms a day. Vitamin D is important for absorption of calcium by the body, which is needed for healthy teeth and bones. A lack of it can lead to serious diseases in both children and adults. The vitamin can be found in some foods but it can also be obtained from chemicals in the skin reacting to sunlight. Dr Barbara Boucher said adults should get 5 to 25 micrograms a day. Shortage of vitamin D may be linked to diseases such as muscle weakness, high blood pressure and rickets . Dr Birgit Teucher gave several reasons for the lack among Britons. Increasing numbers of office-based jobs mean a lack of exposure to the sun; and the rise of becoming overweight means that vitamin D--which is fat soluble is increasingly stored in body fat, where it cannot be accessed readily. Professor Brian Wharton of the Institute of Child Health said that children in particular needed to have enough vitamin D to prevent rickets. Professor Graham Bentham, an environmental scientist at the University of East Anglia, added that babies who were only breast-fed probably need to take supplements in case their mother was vitamin D lacking. Those drinking milk were likely to be OK, thanks to the fortification of the drink. The scientists called on food producers to fortify milk, bread and breakfast nutrient to enable people to get their daily amount of the vitamin. Prof Graham Bentham added that 30 minutes of sun exposure to the face and forearms between April and October would be _ . Outside these months, the sun is not strong enough in Britain for the body to produce its own vitamin D. But Prof Graham Bentham warned against spending too long in the sun. "Sun bingeing is well known to be dangerous," he said. "In any case, vitamin D transformation in the skin switches off after a while so short frequent amounts are better for vitamin D formation." From the passage, we can conclude _ .

"the babies who were only breast--fed certainly need to take vitamin D supplements",
"a large quantity of vitamin D stored in body fat is the primary reason for being overweight",

Special trees that grow faster, fight pollution, produce better wood, and even sense chemical attacks are being planted by scientists in the US. When 40 per cent of Hawaii's US$14 million-a-year papaya industry was destroyed by a virus five years ago, work began on creating genetically engineered trees. Researchers successfully introduced seeds that were designed to resist the virus.Since then, more and more people have been testing genetically engineered trees.Some researchers put special bacteria into trees to help them grow faster and produce better wood.Others are trying to create trees that can clean polluted soil.Meanwhile fruit farmers are looking for trees that are strong enough to resist worms, and paper companies want trees that produce more wood and therefore more paper. The Pentagon even gave the researchers US$500,000 this year after they developed a pine tree that changes its colours if it senses a chemical attack.So far, the poplar, eucalyptus , apple and coffee trees are among those being engineered.All this can be done today because we have a better understanding of tree genomes . However, some people fear that the genetically engineered trees will cause dangerous results.They are worried that the new trees will breed with natural species and change the balance of the forest environment. "It could be destructive," said Jim Diamond, an environmentalist. "Trees are what is left of our natural environment and home to many endangered species." But researchers insist that science could give nature a fighting chance against both natural and man-made dangers.They hope to answer the critics by stopping the new trees from breeding, so their effect on the environment can be controlled. Which kind of tree is not the ones that scientists are planting in the US?

Some recent surveys show that the health conditions of many white collar employees and office workers are rather dangerous. Death cases among white collar employees and office workers are increasing year by year and these cases are generally believed to have been caused by overwork and spending little time taking rest or doing exercise. If their offices are within the distance of half an hour's walk, some office workers now choose to go to work on foot. Ms. Deng, who works in a foreign enterprise in Beijing, has been walking to her office for more than six months now. " I usually have a tight work schedule and can't find time to do exercise. So I choose to walk to work. " As she said, if the office is not far from home, most women would like to go to work on foot. Walking is good for their health and can help them to keep good figures as well. Apart from walking to office,one can also find time to do exercise when one is at work. The simplest way is to desert the lift. Mr. Wei, who works in the Passenger Service Department at Shenzhen Airlines, is one of such men who frequently climb stairs. " I only use the lift whenever I'm with my colleagues or my boss. Otherwise, I would climb stairs instead of taking the lift. " In addition, some office workers try to find time to go to a gym at the end of a day. Ms. Sang works in a law firm in Shenzhen. She goes to the gym several times a week when she has the time. " I go to the gym every weekend. During the weekdays,I will also go there whenever I have the time. " Ms. Sang and her husband both have a gym membership card for a whole year. The cards cost them 3000 yuan. However, they think it's worth it. Why are death cases among white collar employees and office workers increasing year by year?

"The world's oceans are slowly getting more acidic." say scientists. The researchers from California report that the change is taking place in response to higher levels of carbon dioxide in the atmosphere. The lowering of the waters' PH value is not great at the moment but could cause a serious threat to current ocean life if it continues, they warn. Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature. Increasing use of oil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater. Once in the water, it reacts to form carbonic acid. Scientists believe that the oceans have already become slightly more acidic over the last century. These researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change. "This level of acidity will get much more extreme in the future if we continue releasing CO2into the atmosphere," said Dr Caldeira. "And we predict the amount of future acidity will exceed anything we have seen over the last several hundred million years." However, it is not ly clear what that means for ocean life. Most organisms live near the surface, where the greatest PH change would be expected to occur, but deep-ocean life forms may be more sensitive to PH changes.Coral reefs and other organisms whose shells contain calcium carbonate may be affected if the water's acidity levels keep going up, the team predict. In recent years some people have suggested storing carbon dioxide from power stations in the deep ocean as a way of dealing with global warming.But Dr Caldeira said that such a strategy should now be re-considered. "Previously, most experts had looked at ocean absorption of carbon dioxide as a good thingbecause in releasing CO2into the atmosphere we warm the planet, and when CO2, is absorbed by the ocean, it reduces the amount of greenhouse warming." If the water's acidity level keeps rising, _ .

There's no doubt that man is the smartest. But do you know what other animals are smart, too? Dolphins Dolphins are very smart. Most of the "tricks" they're taught to do are actually behavior they would engage in on their own. They love to play, race and generally enjoy their life to the fullest. They speak a language we have yet to completely understand and like all civilized creatures, dolphins' mothers always provide their young children with guidance and possibly, love. Great apes The great ape family primarily consists of gorillas, chimpanzees and orangutans. Their brain chemistry is so similar to humans' that NASA once used chimpanzees in place of astronauts during many dangerous missions. Gorillas have been taught sign language and orangutans exist in complex familial relationships. Elephants Everyone has heard the phrase "an elephant never forgets". Elephants establish long-term friendships, recognizing and remembering their friends years later. If an elephant comes upon a fallen friend, it has even been known to feel sad. Parrots As proved by this list, parrots are very smart. They are also the only animals listed that can actually hold a conversation. Some parrots know hundreds of words by imitating humans.

Do you like to eat sushi ? Many people are afraid to eat it, because they think the bacteria in it might make them sick. However, a new study shows that sea bacteria are good for people. The study finds that a special enzyme from sea bacteria is helpful to humans. It helps people to get more energy from food. To people's surprise, the enzyme is present only in the Japanese. The Japanese traditionally like to eat food rich in seaweed . And the seaweed is rich in this kind of enzyme. However, the enzyme isn't present in all the Japanese. During the study, just 5 out of 14 Japanese had the enzyme. All the Americans studied didn't have the enzyme. "The number is small," said researcher Mirjam Czjzek. "But we can say that this enzyme is present only in the Japanese and not in the North Americans." Then some people think that maybe other people are able to get the enzyme if they eat a lot of seaweed. The study suggests that they collect uncooked seaweed to make their sushi. Restaurant sushi is often cooked, which will destroy the enzyme. So, if you want to get that enzyme, you can travel to Japan to have a taste of the real sushi. Which of the following food has the enzyme?

Each year, road accidents kill a million people and injure millions more. The economic costs are greatest for developing countries. Earlier this year, the United Nations called for a campaign to improve road safety. One way to avoid accidents is better driving. Another is better roads and bridges. Engineers in the Unites States have designed ten new concrete mixtures that they think could make bridges last longer. Professor Paul Tikalsky leads the experiments by a team at Pennsylvania State University. He says bridges made of concrete now last about twenty-five to thirty-five years. But he says the new mixtures might extend that to seventy-five or even one-hundred years. Concrete is made of stone, sand, water and cement . The materials in the cement hold the concrete together. Ancient Romans built with concrete. Yet strengthened concrete bridges did not appear until the late 1800s. People keep looking for new ways to improve concrete. Professor Tikalsky says it is one of the most complex of all chemical systems. The new mixtures designed by his team contain industrial waste products. He says these make the concrete better able to resist damage from water and salt over time. One of the products is fly ash. This is released into the air as pollution when coal is burned. Professor Tikalsky says particles of fly ash are almost exactly the same size and chemical structure as Portland cement. _ is the most costly material in concrete. So using fly ash to replace some of it would save money. The federal government is paying for part of the research. Engineers anywhere can use the technology. Professor Tikalsky says some of the ideas have already been put to use in China, the Philippines and other countries. Which of the following statements is TRUE?

"Ten new concrete bridges have already been built in the United States.",
"A new concrete bridge could last 50 more years than an ordinary concrete one.",

There is nothing in the Hippocratic Oath that tells doctors what to do when they make a mistake with a patient. Nor is there much on this subject in medical school curriculums or in training programs. _ Much was made of the Institute of Medicine's 1999 report that 44,000 to 98,000 people die each year in hospitals from preventable medical errors, many of them made by doctors. The report stated much first-hand information to address the problem, but there was little discussion about how doctors, when they have made mistakes, should deal with their patients, Everyone assumes that the ever-present threat of accusation has made doctors more anxious about admitting error, and no doubt it has, But doctors have always been tight-lipped about their mistakes, in part to preserve an illusion(,) of medical omnipotence Studies suggest that patients are less likely to accuse doctors when they apologize for mistakes, and many hospitals now encourage their physicians to admit their errors. According to an supportive group called The Sorry Works! Coalition, 16 states have already passed laws giving doctors legal immunity for their apologies to patients. Of course, there are plenty of doctors with a nice bedside manner who can get away with bad treatment. How else to explain patients who often line up in court to support doctors accused of malpractice ? The surprising truth is that many patients have a hard time knowing whether they are really getting good medical care. Because so many diseases change randomly over time, patients sometimes spontaneously improve despite improper treatment. On the other hand, a patient who receives exemplary medical care may fare badly simply because the illness is hard to treat. In other words, doctors are often praised or blamed, when the outcome is in fact a chance event. Many, perhaps even most, medical errors probably have little ill effect and go unnoticed by patients. Many lawyers would disagree, but doctors ought to let their patients know when they've made a mistake; it humanizes them and builds trust. What is the author's attitude toward the opinion that the doctor should apologize when he makes a mistake?

Astronomy is the oldest science known to man. Thousands of years ago man looked at the stars and wondered about the heavens. But man was limited by what he could see with his eyes alone. The Greeks studied astronomy over 2,000 years ago. They could see the size, color, and brightness of a star. They could see its place in the sky. They watched the stars move as the seasons changed. But the Greeks had no tools to help themselves study the heavens. Each new tool added to the field of astronomy helped man reach out into space. They did not know that the planet called Saturn had rings around it. Their sight was so limited that they could not see all the planets. In the early 1700s, people thought there were only six planets. Nepture , the last of eight planets to be discovered, was not seen until 1846. Before the spectroscope , man did not know what kind of gases was in the sun or other stars. Without the radio telescope, we didn't know that radio noises came from far out in space. Today, astronomy is a growing science. We had learned more in the last fifty years than in the whole history of astronomy. . When the Greeks watched the stars, they could _ .

There are various ways in which individual economic units can interact with one another. Three basic ways may be described as the market system, the administered system, and the traditional system. In a market system individual economic units are free to interact among each other in the marketplace. It is possible to buy commodities from other economic units or sell commodities to them. In a market, transactions may take place via barter or money exchange. In a barter economy, _ goods such as automobiles, shoes, and pizzas are traded against each other. Obviously, finding somebody who wants to trade my old car in exchange for a sailboat may not always be an easy task. Hence, the introduction of money as a medium of exchange eases transactions considerably. In the modern market economy, goods and services are bought or sold for money. An alternative to the market system is administrative control by some agency over all transactions. This agency will issue commands as to how much of each good and service should be produced, exchanged, and consumed by each economic unit. Central planning may be one way of administering such an economy. The central plan, drawn up by the government, shows the amounts of each commodity produced by the various firms and allocated to different households for consumption. This is an example of complete planning of production, consumption, and exchange for the whole economy. In a traditional society, production and consumption patterns are governed by tradition; every person's place within the economic system is fixed by parentage, religion, and custom. Transactions take place on the basis of tradition, too. People belonging to a certain group or caste may have an obligation to care for other persons, provide them with food and shelter, care for their health, and provide for their education. Clearly, in a system where every decision is made on the basis of tradition alone, progress may be difficult to achieve. An inactive society may result. According to the passage, a barter economy can generate _ .

One Friday morning, Andrew announced to his wife that he finally decided to ask his boss for a salary raise. All day Andrew felt worried --- what if Mr. Larchmont refuses to grant his request? Andrew had worked so hard and of course, he deserves a wage increase. The thought of walking into Larchmont's office left Andrew weak in the knees. Late in the afternoon he finally _ up the courage to approach his superior. To his delight and surprise, the ever-frugal Harvey Larchmont agreed to give him a raise! Andrew arrived home to a beautiful table set with their best china, and candles lit. His wife, Tina had prepared a fine meal including his favorite dishes. Immediately he figured someone from the office might have broken the good news to her! Next to his plate Andrew found a lettered note, reading: "Congratulations, my love! I knew you'd get the raise! I prepared this dinner to show just how much I love you. I am so proud of your accomplishments!" He read it and stopped to reflect on how sensitive and caring Tina was. After dinner, Andrew was on his way to the kitchen when he observed a second card had slipped out of Tina's pocket onto the floor. He picked it up. He read: "Don't worry about not getting the raise! You deserve it anyway! You are a wonderful provider and I prepared this dinner to show you just how much I love you even though you did not get the increase." Suddenly tears swelled in Andrew's eyes. Total acceptance! Tina's support for him was not conditional upon his success at work. The fear of rejection is often softened when we know someone loves us regardless of our success or failure. Tina prepared a good meal, _ .

The Massachusetts Institute of Technology (MIT) is a private research university in Cambridge, Massachusetts, founded in 1861 in response to the increasing industrialization of the United States. The institute stressed laboratory instruction in applied science and engineering. MIT's early emphasis on applied technology at the undergraduate and graduate levels led to close cooperation with industry. Curricular reforms under Karl Compton and Vannevar Bush in the 1930s emphasized basic science. MIT was elected to the Association of American Universities in 1934. Today, the institute comprises various academic departments with a strong emphasis on scientific, engineering, and technological education and research. MIT is one of the most selective higher learning institutions, and received 18,357 undergraduate applicants for the class of 2018 -- only admitting 1,419, an acceptance rate of 7.73%. MIT's 168-acre campus spans approximately a mile of the north side of the Charles River basin in the city of Cambridge. The campus is divided roughly in half by Massachusetts Avenue, with most dormitories and student life facilities to the west and most academic buildings to the east. MIT's on-campus nuclear reactor is one of the most powerful university-based nuclear reactors in the United States. In 1999 Bill Gates donated $20 million to MIT for the construction of computer laboratory named the "William H. Gates Building". While Microsoft had previously given financial support to the institution, this was the first personal donation received from Gates. Other notable campus facilities include a pressurized wind tunnel and a towing tank for testing ship and ocean structure designs. On MIT's campus, you can't find _ .

Being lonely in the crowd might seem ridiculous. But according to a recent survey, the situation is all too common. Loneliness and other anxiety problems - worrying about life's pressures - can even lead to self-murder. An article in China Daily gave no reason for this other than the usual blaming of the post-80s generation. According to a high level official, young people suffering from discouragement are mostly "spoiled and have not been taught to be independent, responsible and express 'thank-you'." Well, how do you like that? First, I don't think China's youth are exactly spoiled. They certainly have more things than their parents did, but a lot of the money spent on them is for their education including various extra classes. Discouragement and anxiety are now the fastest growing challenges in modern societies. We sense a lack of close friends who can talk to honestly and openly. In 1985, a US study found that one in ten people did not have such a friend. In 2006, it was one in four. It's easy to see the connection between loneliness and discouragement. But what actually causes this increasing loneliness? Surely, with Internet social networking sites such as Kaixin, we have more friends than ever. A new study has shown that the more time teenagers spend in front of computers, the less close they are to friends and family.Kaixinor QQ may be fun but it lacks meaning, compared to personal connections in the real world. And then there are those endless online games popular with young Chinese but increasingly there are more interesting choices. For example, new sports such as skateboarding are starting to catch on in bigger cities, as is playing music in a band. These creative hobbies are done in a group and thus friendship can be stronger. Hopefully young people will also be drawn out of the Internet cafes and interactive computer games that in fact fail to recreate a real and interactive experience. According to the text, which of the following can help us avoid being lonely in the crowd?

Researchers at San Diego Zoo have been studying what has been described as the "secret language" of elephants. They have been monitoring communications between animals that cannot be heard by human ears. The elephant's call will be familiar to most people, but the animals also give out growls . Their growls, however, are only partly audible ; two-thirds of the call is at frequencies that are too low to be picked up by our hearing. To learn more about the inaudible part of the growl, the team attached (......) a microphone sensitive to these low frequencies and a GPS tracking system to eight of the zoo's female elephants. The researchers could then relate the noises the animals were making to what they were doing. Matt Anderson, who led the project, told BBC News, "We're excited to learn how they interact and contact with one another." The team has already learned that pregnant females use this low frequency communication to announce to the rest of their long gestation of over two years, in the last 12 days we see the low part of the growl, which we can't hear. This we believe is to announce to the rest of the herd that the baby is upcoming," said Dr Anderson. The researchers believe that this also warns the elephants to look out for coming danger. "You may think that a baby calf of about 300 pounds would not be as open to predation as other species," he says. "But packs of hyenas are a big threat in the wild." Female elephants are only in season for around four days every four years and these calls can be heard by males more than two miles away. By using a sensitive microphone and a GPS tracking system, the researchers wanted to find out _

Books, software, and videos, no matter what you are looking for, if you turn on a computer and log on the Internet, you are sure to find something. E-books are all over the Internet; some are free, and some are not. E-books are basically electronic books you can read without having to carry heavy books and flip through all the pages. Now authors not only sell regular books in bookstores but also sell e-books on the Internet. Some e-books are sold on CDs, too. You can get all types of software right from the Internet. After you download it, you have it. It is so convenient that you can get it even without leaving the house. These are the advantages we have in today's high-tech world. We can find videos of different people. There are so many websites with videos that it would take you some time to actually go through them all. The cool thing about videos is that some people have their own websites or their own spaces where they can upload videos of their families or of different events and allow other people to view them. It is amazing. The Internet is an exciting place and it plays a big part in our lives today. You can even pay your bills on the Internet if that's what you want to do.

Life affects friendships. As we grow, marry, fight in wars, move across the country or change jobs, old friendships fall away and new ones form. As long as we live, the things around us change, and as long as things change, friendships are affected. When we were children we had best friends. No matter what happened we were still friends. We live our lives, however, and do what life calls for us to do, and as we get older, memories fade, faces blur, and even friends' names from childhood are forgotten. Do you have a question about friendship? Do you wonder what to do with a friend who is no longer friendly? Perhaps you will see that you can't control others. If someone wants to be your friend, it is their choice. All you can do is treat them well and do the best for them when you are with them. Then you wish them well when they leave. You can talk to old timers and they will tell you that life is full of incredible joy and incredible sorrow, and that what bothers you today will one day becomes a memory and the sting will be gone. Seniors might tell you that you will learn more as you get older. They will tell you that friendships come and friendships go. Sometimes when they go it will hurt, but you will be okay with it. It's the way life works, after all. What can we learn about friendship, according to the text?

A daughter's duty? Adult daughters are often expected to caregiver for older parents. In 2007, Jorjan Sarich and her dad moved from California to Idaho. It was where he wanted to live his rest time. "I left my occupation, I left my friends; he did the same thing," said Sarich, who bought a house with her father, George Snyder, in the China Gardens neighborhood of Hailey after his health began to decline. Though a graduate student struggling to finish her dissertation , Sarich chose to be her dad's full-time caregiver. "It's only now, several years later, that I'm realizing how much work it was. It's the kind of exhaustion that sleep doesn't cure," she said. About 6 million Americans provide care to elderly relatives or friends living outside of nursing homes. Laurel Kennedy, author of "The Daughter Trap" (Thomas Dunne Books, $25.95), says that women bear a disproportionate share of the burden -- about 70 percent of hands-on care giving such as bathing. "I want to be clear: Women don't hate this," Kennedy said. "What they hate is that everyone just assumes they'll do it." Kennedy is calling for _ equal to the rise of affordable child care and day care: Employers should help working caregivers by offering accommodations. Men should step up more often. It's unfair that women are always chosen to provide care for an elderly family member. Despite the hard work it took on Sarich -- interrupted sleep and the knowledge that his 2009 death was the end game, she would do it again. Since about half a century had gone by, she wasn't the person he remembered, and he wasn't the person she remembered either. Caring for her father changed how each saw the other. Why did Jorjan Sarich caregiver for her father?

Although similar in appearance to hyenas , African wild dogs are nevertheless true wild canine . They are a mixture of black, yellow, and white in such a wide variety of patterns that no two individuals look exactly alike. African wild dogs are widely distributed across the African plains but they do not live in jungle areas. They are social animals, living in groups of usually from 2 to 45 individuals. A hierarchy exists within the group, but the animals are friendly to one another. The young and the infirm are given special privileges within the group. African wild dogs use their sense of sight, not smell, to find their prey. They can run up to 55 km/h for several kilometers. In eastern Africa, they mostly hunt Thomson's gazelles, but they will also attack calves, warthogs, zebras, impalas, and the young of large antelopes such as the gnu. Growing human populations have decreased or degraded the African wild dog's habitat and also diminished their available prey. Road kill and human persecution have also had a negative impact on African wild dog populations. This species is also _ to a variety of diseases such as distemper, which is controlled in domestic .dogs. Conservation of the African wild dog's natural habitat must have the highest priority, as these dogs suffer in habitats modified by human intrusion . What can we infer from the passage?

A machine that takes sweat-laden clothes and turns the moisture into drinking water is in use in Sweden. The device spins and heats the material to remove the sweat, and then passes the vapor through a special membrane designed to only let water molecules get through. Since its Monday launch, its creators say more than 1,000 people have "drunk others' sweat(h)" in Gothenburg. They add the liquid is cleaner than local tap water. The device was built for the United Nation's child-focused charity UNICEF to promote a campaign highlighting the fact that 780 million people in the world lack access to clean water. The machine was designed and built by engineer Andreas Hammar, known locally for his appearances on TV tech show Mekatronik. He said the critical part of the sweat machine was a new water purification component developed by a company named HVR in collaboration with Sweden's Royal Institute of Technology. "It uses a technique called membrane distillation ," he told the BBC."We use a substance that's a bit like Gortex that only lets steam through but keeps bacteria, salts, clothing fibers and other substances out."They have something similar on the International Space Station to treat astronaut's urine - but our machine was cheaper to build. Volunteers have been sampling the treated sweat since the start of the week in Gothenburg ."The amount of water it produces depends on how sweaty the person is - but one person's T-shirt typically produces 10ml , roughly a mouthful." The equipment has been put on show at the Gothia Cup - the world's largest international youth football tournament. MattiasRonge, chief executive of Stockholm-based advertising agency Deportivo - which organized the stunt - said the machine had helped raise awareness for UNICEF, but in reality had its limitations. "People haven't produced as much sweat as we hoped - right now the weather in Gothenburg is lousy," he said."So we've installed exercise bikes alongside the machine and volunteers are cycling like crazy."Even so, the demand for sweat is greater than the supply. And the machine will never be mass produced - there are better solutions out there such as water purifying pills." What can we infer from the passage ? _ .

As we all know, any country has good reasons to want its citizens to be as healthy as possible. This led to the introduction of a health service in many countries. France has developed into a country in which all citizens can get most of the health treatment free. The money for this is partly from the people who are willing to offer. But there are different opinions about the Health Service. The number of patients treated every year and the cost of treatment are much greater than expected. This means that the people who work for the Health Service --- doctors, nurses and other hospital workers, have much more work to do, and as a result they have little time for preventive treatment. However, the tough problem is that as many people are able to receive treatment more expensive than they can pay, sometimes people go and visit their doctors when they don't really need to. As there are many patients, doctors cannot spend time long enough with each patient. So some people prefer to pay for their own treatment so that their doctors can examine them more carefully. In fact, some rich people feel that they should pay more free money, which would be given to other citizens. Why do many people go and see the doctors even when they really don't need to?

The most frightening words in the English language are, "Our computer is down." You hear it more and more when you are on business. The other day I was at the airport waiting for a ticket to Washington and the girl in the ticket office said, "I'm sorry, I can't sell you a ticket. Our computer is down." "If your computer is down, just write me out a ticket." "I can't write you out a ticket. The computer is the only one allowed to do so." I looked down on the computer and every passenger was just standing there drinking coffee and staring at the black screen. Then I asked her, "What do all you people do?" "We give the computer the information about your trip, and then it tells us whether you can fly with us or not." "So when it goes down, you go down with it." "That's good, sir." "How long will the computer be down?" I wanted to know. "I have no idea. Sometimes it's down for 10 minutes, sometimes for two hours. There's no way we can find out without asking the computer, and since it's down it won't answer us." After the girl told me they had no backup computer, I said. "Let's forget the computer. What about your planes? They're still flying, aren't they?" "I couldn't tell without asking the computer." "Maybe I could just go to the gate and ask the pilot if he's flying to Washington, " I suggested. "I wouldn't know what gate to send you to. Even if the pilot was going to Washington, he couldn't take you if you didn't have a ticket." "Is there any other airline flying to Washington within the next few hours?" "I wouldn't know, " she said, pointing at the dark screen. "Only 'IT' knows. 'It' can't tell me." By this time there were quite a few people standing in lines. The word soon spread to other travelers that the computer was down. Some people went white, some people started to cry and still others kicked their luggage.

Picture the scene: the battery on your mobile phone has run out. You can't make any calls for help and no one can contact you. You are all alone - well, not quite. Just reach into your pocket and take out a piece of sugar.Put it into the battery, wait a minute, and you're back on the phone. Thanks to a couple of American scientists, this situation could become real.Swadesh Chaudhuri and Derek Lovely have invented the "bacteria battery" - powered by bacteria that eats sugar and turns it into electricity. "This is a special organism," Lovely said."You ean harvest enough electricity to power a cell phone battery for about four days from a spoonful of sugar." In the past, bacteria batteries have been expensive and not long-lasting. But this battery uses more efficient bacteria that can turn 80 percent of sugar into electrical energy. This is 30 percent more than similar batteries can manage. The bacteria battery could become as small as a household battery. It's also cheap and stable, as sugar can be taken from waste and crops. But the sugar to electricity process is slow: it could take weeks for the bacteria to digest a cup of sugar.And it produces "greenhouse" gases which pollute the environment. The scientists understand there is a lot more work to be done. "It is still young," said Lovely."Where we are now is where solar power was 20 0r 30 years ago." But he believes the battery could be used in scientific equipment at the bottom of the ocean.Other ideas include using sugar in the blood to run medical devices in the human body, and taking sugar from animal waste to provide energy to power homes in rural areas. Which of the following is not the strong point of the newly-developed battery?

At noon, Shi Huizi received a text message: "This is Yuantong Express. Please come to the school gate and pick up your parcel." The 22-year-old girl at Beijing International Studies University rushed to the school gate, where hundreds of parcels lay waiting to be collected by their owners. This scene is not uncommon on China's campuses, as shopping online has become an important part of their lifestyle for many university students. But convenient as it is, online shopping among students is marked by impulse buying and other risks. Students should be cautious to avoid them. According to Taobao, during last year's graduation season, 250,000 graduate students from 116 "211" project universities nationwide spent 846 million yuan on Taobao. Beijing Haidian Consumers' Association conducted a survey on the online purchasing behavior of students, which showed that nearly 54 percent of respondents had made _ purchases. Yang Yi is one of them. The 23-year-old business administration major at Beijing Wuzi University bought a limited edition Gundam model kit online for a small fortune, only to find that its appeal faded rapidly. "I did like it when I bought it, but it doesn't look so attractive to me anymore now. So I've decided to sell it to pay off my debts," says Yang. Yang's experience reflects the consumption patterns of many university students. In an attempt to be unique, many of them turn to online shops to buy "exotic " items not easily found in the domestic market. According to Lei Li, a psychology professor at Renmin University, the impulsive buying patterns found among students have psychological roots. When shopping online is a campus trend, it's not only about convenience, but also about group identification . "If everyone is doing something and you're not, you're less likely to be accepted by others," Lei says. The mentality of not wanting to be left out is fuelling impulse buying. As he Haidian survey indicates, online shopping is not always a satisfying experience. Of 848 respondents from universities based in Beijing, 42 percent said they had received products that didn't match the online description or photos. Even so, 72.5 percent of student buyers don't return unsatisfactory goods due to the inconvenience it causes and long procedures. Lei suggests that students who are enthusiastic about online shopping "pay attention to the consequences and develop a wiser way of consuming--namely, buying items within their budget and being aware of the risks of buying online." What's the best title of the passage?

Noise pollution in cities is causing out health to suffer, according to the World Health Organization. Recently, researchers at the Free University of Brussels in Beigium have developed an applocation: NoiseTube. It allows everyone who downloads it the ability to measure the amount of noise they are exposed to by transforming their smart phone into a sound level meter. NoiseTube works by recording sound levels and GPS locations. Once launched the app shows decibel levels of green or red depending on the level of noise. That information is then sent to the NoiseTube server via the Internet where a "noise map" is produced and then made available to the user. Since its launch, the app has been popular with community groups who want to monitor their own noise levels. According to D'hondt of the Noise Tube project, these groups don't think that city produced noise maps give an adequate interpretation of the level of noise they're experiencing. City produced noise maps are based on statistical models involving very few actual measurements. NoiseTube on the other hand gives a detailed account of the level of noise experienced at a specific time and location. "Ten people walking the same area from 9 to 10 am every day for one week can make a valid and detailed map for an area of a couple of blocks," D'Hondt said. "It's reasonable effort by the community groups to produce these maps, and with it they can go to the authorities and have real evidence about what they're experiencing." So far these sorts of noise maps have been produced for a number of European cities. The app has been downloaded by 10,000 people with 2,700 people registered on the NoiseTube website. The reliability of city produced noise maps is questionable because _ .

The latest fashion in the kitchen is the food steamer.All the stores are selling them;everyone wants one.Steaming is one of the simplest and healthiest ways of cooking food.However,that cooking time is usually longer than with other methods.In case you're thinking of buying a steamer,I've done a survey about the steamers available on the market to help you decide which will suit you best. Folding Steamer The simplest and least expensive is the folding stainless-steel version. Advantages:This is a good,basic design which sits inside a variety of different shapes of pans with the water under it;a ring in the centre allows for easy lifting and it's easy to clean. Disadvantages:It only holds small dishes.Also,if you put too much water in the pan,it will boil up through the vegetables and they will be watery.If you put too little water in and let it get dry,you will burn the pan and get strange-smelling vegetables. Steaming Pan This is a three-layered black Teflon-coated version with a lid and two double-handled steamers,which sits on the oven ring.The brand I bought is calledNutritious Living. Advantages:This is an excellent steamer, lightweight,easy to clean,and of all the steamers I've tried,this cooks the fastest.Fish and chicken can be cooked on the bottom with rice or vegetables on the top.It's easier to store. Disadvantages:Water can boil away until the pan is dry,but if you make sure you fill the pan up to the suggested level and do not overcook the food,this should not happen.You cannot see the food cooking from the top.It doesn't supply a dish for cooking rice. For serious users of steamers,I recommend having one of each version.If you just want to try it,get the folding stainless-steel type. Which of the following is true about the folding steamers?

The Internet began in the 1960s as a small network of academic and government computers primarily involved in research for the prefix = st1 /U.S.army. Originally limited to researchers at a handful of universities and government departments, the Internet has quickly become a worldwide network providing users with information on a range of subjects and allowing them to purchase goods directly from companies via computer. By 1999, 84 millionU.S.citizens had access to the Internet at home or work. More and more Americans arc paying bills, shopping, ordering airline tickets, and purchasing stocks via computer over the Internet. Internet banking is also becoming increasingly popular. With lower overhead costs in terms of staffing and office space, Internet banks are able to offer higher interest rates on deposits and charge lower rates on loans than traditional banks. "Brick and mortar" banks are increasingly offering online banking services via some special websites to enlarge their traditional services. At present, 14 percent of Internet households conduct their banking by means of the Internet, and the figure is expected to double during the next two or three years. Increasing commercial use of the Internet has heightened security and privacy concerns. With a credit card, an Internet user can order almost anything from an Internet site and have it delivered to their home or office. Companies doing business over the Internet need many security measures to protect credit card, bank account, and social security numbers from unauthorized access as they pass across the Internet. Any organization that connects its networks to the global Internet must carefully control the access point to ensure that out-siders cannot disturb the organization's internal networks or gain unauthorized access to the organization's computer systems and data. The term "brick and mortar banks"(Line 3, Para.2)refers to

Water Pollution and Man Water pollution affects man's health, recreational use of water and sense of beauty. The spread of water-carried disease is of great concern. In highly developed countries in particular, emphasis has changed from concern over bacterial disease to concern over water-carried viral disease. Viral hepatitis , for example, has been found to occur more frequently in cities whose water supplies have comparatively high levels of water impurity. Poisonous chemicals found in streams that are ultimately used for water supplies also create an important public health problem. It is clear that poisonous chemicals must be excluded from water, but more and more chemicals from new pesticides , fertilizers, and other new products have been found in water. Since the public health importance of these chemicals is not yet fully known, they are of increasing concern. The chemicals from fertilizers are also finding their way into water supplies from pollution. As man's desire for water-based recreation increases, greater demands are placed on the quality of the water. The water must not only but be attractive in appearance but also meet certain other conditions. Sports such as swimming involve direct contact with water, and so water standards are raised higher. The range of water quality necessary for industrial processes varies greatly with the intended use of the water. The water used in steel mills, foe example, must have a lower chloride level than that accepted for drinking water. Cooling water can often be of comparatively low sanitary quality. A large part of the water used in the paper-making industry an be of ly low quality in some aspects, but must contain little iron and carbon dioxide. As the passage is not complete, what do you think would follow in its full text? _
