A purple tomato genetically engineered to contain nutrients more commonly seen in dark berries helped cancer in mice, British researchers said on Sunday. The finding, published in the journal Nature Biotechnology, the idea that plants can be genetically modified(changed) to make people healthier. Cancer-prone mice fed the modified fruit lived significantly longer than animals fed a standard diet with and without regular tomatoes, Cathie Martin and colleagues at the government-funded John Innes Center in Britain reported. "The effect was much bigger than we had expected." said Martin, a plant biologist. The study focused on anthocyanins,a type of antioxidant found in berries such as blackberries and blackcurrants that have been shown to lower risk of cancer, heart diseases and some neurological diseases. While an easy way to improve health, many people don't eat enough of these fruits, the researchers said. Using genes from the snapdragon flower, the researchers discovered they could get the tomatoes to make anthocyanins---- turning the tomato purple in the process. Mice genetically engineered to develop cancer lived an average of 182 days when they were fed the purple tomatoes, compared to 142 days for animals on the standard diet. "It is greatly encouraging to believe that by changing diet, or specific components in the diet. You can improve health in animals and possibly humans." Martin said in a telephone interview. The researchers warned that trials in humans are a long way off and the next step is to investigate( look into) how the antioxidants actually affect the tumors to promote better health. But the findings do support the formal research suggesting that people can significantly improve their health by making simple changes to the daily diet, other researchers said. "It's exciting to see new techniques that could potentially make healthy foods even better for us." said Doctor Lara Bennett, science information office at Cancer Research UK. " But it is too early to say whether anthocyanins obtained through diet could help to reduce the risk of cancer." Which of the following was NOT the result found in the study?
|
[
"Blackberries and blackcurrants can lower risk of cancer.",
"The anthocyanins can make the purple tomatoes grow stronger.",
"Genes from snapdragon flowers can be put into common tomatoes.",
"Mice fed the modified fruit lived longer than the common ones."

Most animals protect their young until they are old enough to take care of themselves. A fish that swims in the rivers of South America protects its young in a very strange way. This fish, a kind of catfish, uses its mouth to keep its babies from danger . When this catfish lays its eggs, it carries them in its mouth. From what we know, it does not eat during this time. After the eggs hatch , the fish swims with its young to protect them. It opens its mouth when danger appears , and the tiny fish swim inside. They swim out only when it's safe again. These catfish may have a _ way to protect their young, but it seems to work. If the young fish were not near their parents, they would be _ .

It's important for us to be healthy. But how can we keep healthy? First,you should eat fruit and vegetables three or four times a week. Then eat some tofu every day because it's good for people, both the young and the old. Milk is also necessary ,especially for women. So you should have milk twice a day. It can help you to be strong. Next, doing more exercise is better. You can do morning exercises or evening exercises. After supper you should take a walk. Why do people have milk?

There are an extremely large number of antsworldwide. Each individual ant hardly weigh anything, but put together they weigh roughly the same as all of mankind. They also live nearly everywhere, except on frozen mountain tops and around the poles.Foranimals their size, ants have been astonishingly successful, largely due to their wonderfulsocial behavior. In colonies that range in size from a few hundred to tens of millions, they organize their lives with a clear division of labor. Even more amazing is how they achievethis level of organization. Where we use sound and sight to communicate, ants dependprimarily on pheromone , chemicals sent out by individuals and smelled or tastedby fellow members of their colony. When an ant finds food, it produces a pheromone that will lead others straight to where the food is. When an individual ant comes under attack or is dying, it sends out an alarm pheromone to warn the colony to prepare for a conflict as a defense unit. In fact, when it comes to the art of war, ants have no equal. They are completely fearless and will readily take on a creature much larger than themselves, attacking in large groups and overcoming their target. Such is their devotion to the common good of the colony that not only soldier ants but also worker ants will sacrifice their lives to help defeat an enemy. Behaving in this selfless and devoted manner, these little creatures have survived on Earth, for more than 140 million years, far longer than dinosaurs. Because they think as one, they have a collective intelligence greater than you would expect from itsindividual parts. Which of the following contributes most to the survival of ants?

Science can't explain the power of pets, but many studies have shown that the company of pets can help lower blood pressure and raise chances of recovering from a heart attack, reduce loneliness and spread all-round good cheer. Any owner will tall you how much joy a pet brings. For some, an animal provides more comfort than a husband/wife. A 2002 study by Karen Allen of the State University of New York measured stress levels and blood pressure in people - half of them pet owners -while they performed 5 minutes of mental arithmetic or held a hand in ice water. Subjects completed the tasks alone, with a husband/wife, a close friend or with a pet. People with pets did It best .Those tested with their animal friends had smaller change in blood pressure and returned Most quickly to baseline heart rates .With pets in the room ,people also made fewer math mistakes Than when doing in front of other companions. It seems people feel more released around Pets, says Allen, who thinks it may be because pets don't judge. A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits. Researchers at Northwestern Memorial Hospital spent a Year studying 36 fat people and were put on a diet-and-exercise programs; a separate group of 56 fat people without pets were put on a diet program. On average,people lost about 11 pounds, Or 5% of their body weight .Their dogs did even better,losing an average of 12 pounds,more then 15%of their body weight .Dog owners didn't lose any more weight than those without dogs but ,say Researchers,got more exercise overall -mostly with their dogs -and found it worth doing. We learn from the text that a person with heart disease has a better chance of getting well if _

A California family drives a car that could help protect the environment. When Jon and Sandy go to the store or to their daughters' soccer games, they drive in high-tech style. They drive a $1 million, fuel-cell-powered car. It may be the world's most expensive car and one of the most environmentally friendly cars. The FCX is the first fuel-cell-powered car to be used by a family anywhere in the world. The FCX uses hydrogen and oxygen for fuel. Car makers have been working to develop vehicles that are better for the environment. They are developing cars that use fuel other than gasoline. And then what is fuel cell technology? Fuel cell technology works by changing the chemicals hydrogen and oxygen into water. This process produces electricity, and water vapor which comes out of the exhaust pipe. Most cars release dangerous gases such as carbon monoxide and carbon dioxide. Many scientists say these gases are major contributors to global warming. "The FCX is driven just like any other vehicle on the road, but without the gases which pollute the environment," scientists say. Fuel cell technology has been around since the 1800s, but scientists have yet been to perfect it. They say it may take years before the technology is ready for widespread use. Another earth-friendly car is already on the market. Hybrid cars use both gasoline and an electric motor. They are becoming more popular with customers because they cut pollution and improve fuel efficiency. Which of the following about the FCX is not true?

Driving speeds have largely stabilized, and nowadays, safety concerns are important and reducing road accidents to minimum is a must. So, automakers are focused on safety systems more than ever before. Given the emphasis on improving safety, it's possible that well-known phrases such as "live fast and die young" may lose their meaning as innovative new devices are built into cars and trucks and other things that go. Many of the new safety systems that are being added to high-end vehicles are computer-assisted technologies that transfer some of the vehicle's operations to the vehicle itself, rather than relying only on the driver's decision-making skills. For example, predictive brake assist is an in-vehicle feature that prepares the vehicle for braking when its built-in sensors detect a potential object ahead. The predictive brake assist basically places the vehicle's braking system on alert, which helps the system to slow down the car in as little time and as short a distance as possible. Other in-vehicle sensors will detect moving and still objects and will even distinguish the objects based on simple patterns, such as other vehicles vs. a person. What's more, built-in "active systems", i.e., predictive precollision systems, will provide drivers with advance detection of potential contact between vehicles. These systems compute the movement of the objects and detect possible dangerous intersections . What technological developments have enabled innovations like predictive precollision systems? Essentially, these so-called active systems are the result of vehicle-to-vehicle and vehicle-to-infrastructure communications. These communication links allow highways to provide a vehicle's owners with services such as renting a movie during the trip, as well as reduce reaction delays when medical care is needed due to a crash. Despite these new technologies, drivers cannot take safety for granted. Until all vehicles are fully automated, it is the drivers themselves who are responsible for operating their vehicles and obeying traffic laws designed to keep roadways secure. So, keep your eyes on the road and your hands on the steering wheel . Which of the following would best serve as the title for the passage?

"New systems, safer driving",
"New technology, relaxed drivers",

Analysis of the composition of quicksand shows that there are four key ingredients--sand, obviously water, clay and salt. Together these materials form a structure resembling a house of cards, with large water-filled gaps between the sand particles, which are loosely glued in place by the clay. As long as it's left alone, the structure remains stable. But as soon as it's disturbed, by stepping on it, the clay changes from a jelly-like consistency to a runny liquid. The effect is the same as stirring a pot of yoghurt. Liquefying the clay makes the quicksand about one million times runnier, and the whole house of cards comes tumbling down, with you inside it. Very quickly, the sand sinks to the bottom and the water floats to the top. This is where the salt comes in. When there's enough salt present, as soon as the clay particles liquefy, electrical charges make them begin to stick together to form bigger particles and these also settle with the sand. Quicksand is a mixture which looks like solid, but behaves more like a liquid. Despite its murderous reputation, quicksand does not such people under and swallow them, although it can hold a person in firm grip. The human body is more buoyant in quicksand than in water, and sooner or later anyone trapped in it will float. Unlike most liquids, quicksand's viscosity, or "runniness" can suddenly change if it comes under pressure, for example under a human foot. The surface gives way and the victim quickly sinks in up to the knees, surrounded by an area of dirty things that turns semi-solid around its victim. Escaping from the quicksand's grip requires a large amount of force. Without something solid to pull at, people often find they are stuck fast. Pulling at one leg simply makes the other one sink further. So how do you escape from quicksand's control? Stay still and call for help. Staying still stops you sinking any further, until--with luck--help arrives on the scene. If no one appears and you need to draw yourself out, gently lie down on your back until your body is floating on the sand. Next, roll over onto your stomach and pull yourself forwards with your hands, so that you gradually "swim" towards firmer ground. It is a slow and dirty business, but it works. This technique has one barrier: it goes against a very powerful human nature. Faced with danger in the open, nine out of ten stay on their feet so that they can run away, in which case it can worsen the situation. Which ingredient of the quicksand make someone trapped in it stuck and stuck fast?

Many textbooks are not written in the kind of English that we speak every day. In fact, sometimes the reading is so difficult that it almost seems like a foreign language. In a way, it is--the language of science. You should not expect to be able to read a difficult science passage the same way you read an interesting story; you should not expect to read it easily and all at once. Instead, you may have to read it several times through, catching on the meaning of difficult words, going back over difficult sentences, and finally putting the whole thing together. Do not be discourages if the whole passage don't make sense to you at first. You need to pick it apart patiently until you can understand it. These are the steps to follow when you are reading something difficult: 1. Start to read normally until you _ a sentence that doesn't make sense to you. 2. When a sentence doesn't make sense, go back and read it again more slowly. 3. Look for any word you don't know in the sentence. Try to understand their meanings using word parts and context clues . If necessary, look them up in the dictionary. 4. Look at the next few sentences to see if they explain more about the sentence you are working on. Do not read very much farther ahead until you understand what is being said. 5. Finally, read the sentence again. Try to put it into simpler words. 6. Read through the passage once. Try to understand all the hard parts well. Then read the whole passage once more at a usual speed. This helps you to put all ides together. The stops sound a lot harder than they are. It is really just the normal way good readers understand anything that is difficult to read. After you have done the best you can this way, you should always feel free to ask for help from your teacher, if you have one. The massage is mainly about _ .

If you want to stay young,sit down and have a good think. This is the research finding of a team of Japanese doctors, who say that most of our brains are not getting enough exercise, and as a result,we are ageing unnecessarily soon. Professor Taijiu Matsuzawa wanted to find out why otherwise healthy farmers in northern prefix = st1 /Japanappeared to be losing their ability to think and reason at a ly early age, and how the process of ageing could be slowed down. With a team of partners at Tokyo National University,he set about studying the brain volumes of a thousand people of different ages and various jobs. Computer technology enabled the researchers to get exact measurement of the volume of the front and side sections of the brain,which relate to intellect and feelings,and determine the human character. The back section of the brain,which controls functions like eating or breathing,does not connect with age. One can continue living without intellectual or feeling abilities. Contraction of front and side parts - as cells die off - was observed in some subjects in their thirties, but it was still not obvious in some sixty and seventy year olds. Matsuzawa concluded from his tests that there is a simple cure for the contraction normally connected with age using the brain. The findings show in general conditions that contraction of the brain begins soon among people in the country than in the town. Those are at least at risk,says Matsuzawa,who are lawyers,followed by university professors and doctors. White collar workers doing regular work in government offices are, however,as likely to have shrink as the farm workers,bus drivers and shop assistants. Matsuzawa's findings show that thinking can prevent the brain from shrinking. Blood must flow through a circle properly in the head to supply the fresh oxygen the brain cells need. "The best way to keep good blood movement is through using the brain,"he says. " Think hard and engage in conversation. Don't depend on pocket calculators.

As most university students are packing their bags,boarding trains or flying home for the Spring Festival,some will stay behind to spend the holiday on campus. Zhou Yunyun,22,a senior finance major at Jilin University,has decided that instead of traveling to Hainan province,he will kill the time by playing computer games with his online friends. "I'm used to chatting and playing with them every day.It's just fun to make friends this way,"he said."When I returned home in past years,my relatives always asked me a lot of questions about my plans after graduation.They had high expectations of me,which made me feel stressed," said Zhou. The campus,usually lively,will probably turn into a death town,with most restaurants,shops and student centers closed during the break.But there are also a few advantages,according to Jia Debao,2 1,a junior majoring in administration at China Agricultural University."I might feel a bit lonely,but at least I can stay away from my parents' complaining and enjoy the peaceful and quiet stay," he said."More importantly,I can enjoy the high speed of the Internet,I can always find empty seats in classrooms,and I don't have to wait to use the bathroorm" But education experts recommend students who stay on campus to come up with more interactive plans.That's because communication on the Internet can't replace real life interpersonal relationships. Society has promoted a kind of" _ " or close-in culture among some young people, according to Shi Tongyu, a researcher at the Chinese Academy of Social Sciences. He warned that this kind of lifestyle can damage students' mental and physical development. "When you constantly stare at a computer screen and type on your keyboard,you gradually lose the ability to socialize and survive normally,"said Shi."A human's most important task is to survive,which cannot be completed by staying at home all the time. Instead,it must be achieved through real life experience and communication." What do education experts recommend students to do?

On Jan. 13th, 2009, the Peanut Corporation of prefix = st1 /Americaissued a recall for products it had made over the past six months, after five people had died and more than 400 had fallen ill with salmonella poisoning as a result of contamination. Two weeks later, the recall was extended to more than 400 consumer products made since Jan. 1, 2007, including Jenny Craig nutritional bars and Keebler Peanut Butter Sandwich Crackers, while the toll from the contamination had reached eight dead and more than 500 sickened in 43 states, half of them children. The company's factory in Blakely,Ga., which was the source of the contamination, supplied some of the largest food makers in the nation. The outbreak showed the complexities of the industrial food chain, and left consumers to figure out if some food in their cabinets had a danger. The recall of peanut products is the latest in a series of increasingly severe food contamination scares involving tomatoes, spinach, cantaloupes and other foods. TheGeorgiaplant, which is closed, packed peanut butter in bulk ranging from 5 to 1,700 pounds, much of which was shipped to institutions. Many school districts have pulled peanut butter from menus, with some substituting more commonly recognized supermarket brands. New York City school officials said they had not bought any peanut butter or products with ingredients that originated at theGeorgiaplant. An F.D.A. inspection team that visited the plant on Jan. 9 discovered that on 12 occasions in 2007 and 2008 tests conducted by the company found salmonella contamination in its products but that it shipped the contaminated products to customers after a retest found no contamination and did nothing to clean the plant. What can be inferred from the fact that the recall was extended?

Millions of years ago dinosaurs lived on the earth. In the days of dinosaurs the whole earth was warm and wet. There were green forests and they could find enough to eat. Later, parts of the earth became cold and dry. and the forests there died. Then dinosaurs could not find enough to cat. This must be one reason why dinosaurs died out. We can guess another reason. New kinds of animals came on the earth. Some had big brains and were fast and strong. They could kill dinosaurs. There may be other reasons that we don't know about yet. Scientists are trying to make more discoveries about dinosaurs. Dinosaurs were of many sizes and shapes . Some were as small as chickens, while some were about 90 feet long. There were also terrible fights between dinosaurs. They might have happened more than 100 million years ago. Though there was no man to see any of the fights, we can be told by the animal's footprints that fight did take place. According to the passage, dinosaurs did exist only _ on the earth.

Anyone who ever wondered why a dying plant, say, a freshly-cut red rose may appeal to a lady friend, might take some comfort in science, which once again offers us a reasonable answer to one of the world' s great mysteries. Beyond a common preference in people for blue, "the long history of color preference studies has been described as 'confusing and contradictory '," write scientists Anya Hurlbert and Yazhu Ling of England' s Newcastle University, authors of a new study in the journal Current Biology. "This fact is perhaps surprising," they said, "though the popularity of the concept that little girls differ from boys in preferring pink." But the scientists believe they have an answer to this scientific mystery, discovering women's preference for red, hidden above the average liking for blue. In their study, the pair quickly flashed color cards, displaying many different aspects, at 208 volunteers, mostly Britishers but with a number of Han Chinese, who moved to the United Kingdom recently. Tested in three different experiments, the researchers found out a small but significant preference for reddish colors in the female volunteers. Puzzled, the authors realized that most of the difference between men and women came in the form of a preference for green VS red in the color cards, regardless of the other slight differences such as the slightly blue ones that everyone liked. Why might this be? Evolution might offer an answer, they reason. Human color perception , the assessment of three separate color types -- red -- green -- blue-- in our vision is a relatively recent addition to our line of mammals Adding weight to their argument, they found the women who are most typically feminine on a psychological survey also had the biggest preference for reddish colors. "My love is like a red, red rose," wrote the Scottish poet Rober Burns in 1794. The word "pair" in Para.4 refers to _ .

Ask anybody out there, what is the most important thing in his life - Fame, Fortune and Money, and there is a chance that he is going to say, money, because with that, fame and fortune comes quite easily. On the other hand, if you add "family" to these three choices given above, there is a chance that 99% of the people are going to put their family first, especially if they happen to be ladies! The main reason is because nature has created a woman to be the cherisher and the nurturer of the family, while the man is the hunter and protector of his little family. That is the natural rule which has come down through thousands of years. Even if a person happens to be a comparatively worldly-wise person and has no idea of taking on the responsibility of a family, he has a picture of a tight little _ in his subconscious . They tell a story about a successful millionaire businessman who died and the whole city came to pay its respects. One of his business competitors, met the son and said, "We are really going to miss your father. You see, I knew your father well." And the son replied, "You happen to be really lucky there, because I never did." So, you might be an extremely successful person in your own right upon Wall Street, but if your little child fails to come running out to welcome his daddy at the end of the day to be swung up in his father's arms and held there lovingly and protectively, you come in the "nothing" category in the business of life. Many people are under the impression that taking on the responsibility of the family is quite tiresome, but they do not know what it takes to be a parent. It is very easy to be a biological father or a biological mother, but the real mother and the real father is that person who stays awake all night when the baby is teething, teaches him right from wrong, is there to hold him when he takes his first steps, and in every way shows that he is there to cherish and protect the little one from harm. There was a man who did not believe in family, because of an unhappy childhood. But he found a faithful woman to love him unconditionally. The moment he picked up his little baby, he said, "Well son, welcome to the world! I am here to teach you what your mama has taught me, and we shall both protect you, when you need our help. I will teach you to be a good, just and fair man." What might be the title for the passage?

If we find a bird nest, we will have a good place of observing and knowing about birds. Birds sit on eggs and take care of their baby birds from April to June. Because the baby birds are too young to leave the nest, mothers often leave and come back to the nest during the time to look for food. So it is good to observe birds. When we observe birds, we'd better hide ourselves in a close place to the nest, and it's better to use binoculars . But how to make a bird nest? It's very easy. If you want to make one, please follow these: Making a nest: A good nest must be very fine, strong, thick and easy. a) Each nest must have six boards. Don't make the boards too slippery. [:Zxxk.Com] b) Dig a small hole in the front of the nest as a door. The "door" is from 3cm to 5cm. So the bird can fly in or out easily. c) Make sure the rainwater doesn't go into the nest. d) One piece of the boards should be easy to open. e) Please don't forget to color the nest. The most important thing in observing birds is to _ .

Humans are well-equipped for life on Earth. But in space, it is different. Low or _ changes how the blood flows and causes motion sickness, muscle loss and tiredness. Weightlessness can also cause bone loss. But scientists are experimenting with little worms to better understand how space travel affects astronauts. The millimeter-long worm is called C. elegans. The see-through worm is often used in medical studies because its life is only about two weeks long. Seventy percent of its DNA is the same as human DNA. Sabanayagam is a scientist, who built a micro-gravity simulator to test how C. elegans would perform in the actual zero gravity of space. Scientists put the worms into the simiulator full of water. After a week they take out the worms. They look for changes in the worms' epigenome,which are chemical markers that tell the DNA in the cells how to perform. The epigenome can be changed by the environment. And those changes pass from one generation of worms to the next. "When the worms are in a liquid environment, some epigenomic marks remain even when we take the animal out of the liquid environment and put it back into normal ground conditions. So its offspring keeps this epigenomic memory of the parents' liquid environment or microgravity environment." The information the scientists have gathered suggests that the epigenomic marks appear during the early part of a worm's life. Mr. Sabanayagam says he thinks scientists can find genes in the human similar to those in the worms that responded to microgravity and scientists could possibly observe those genes closely when astronauts travel in space. Sabanayagam expects C. elegans to visit the International Space Station within two years. He says he hopes information gathered from the worm studies can be used to develop simple, low-cost and quick tests to measure an astronaut's health. From the passage we can know C. elegans _ .

Dogs are known for a strong sense of smell. Their noses can be trained to identify different smells. Dogs are often used in search and rescue operations and to sniff for things like drugs and explosives. Some dogs have even been trained to sniff for cancer in people. Researchers have been trying to reproduce the extraordinary sense of smell that real dogs are born with. Now, officials at the Glasgow airport in Scotland are testing a new security device called an "electronic sniffer dog". The electronic sniffer dog represents one of the latest developments in the area of smell technology. A Scottish company, Cascade Technologies, joined with the French security company Morpho to develop it. The device uses lasers to identify explosive materials in gases in the air. The purpose is to identify explosives that may be hidden on a person's body. The machine looks similar to the metal detectors now used at airports. Passengers walk through the machine as the lasers test the surrounding air. People are not required to take off their coats, belts or shoes as part of the security process. And, unlike full-body scanners, the new device does not show images of the passengers. Officials at Cascade Technologies say the machine can process one person per second and produce almost immediate results. They say future development could cut security processing times at airports by screening all passengers at walking speed. Professor Yushan Yan, the head of Chemical and Environmental Engineering at the University of California, Riverside, points out that unlike real dogs, electronic devices do not get tired or need to be walked or require food and water. Professor Yan says real dogs also have other needs. "They also need very extensive training that could be expensive. And when they work they have to have a very skilled handler around them." But Professor Yan says there is an important area where man's best friend still wins compared to technology. "In terms of sensitivity and selectivity, the current technology out there is still _ . The real dog has amazing capability of identifying some really minor amount of explosives." The advantages of the electronic sniffer dog over the real dog include the following EXCEPT _

Babies love chocolate and sometimes they also eat the paper around it. My cat enjoys a meal of goods, thick paper and letters, for example. She doesn't like newspapers very much. Of course, the best paper comes from wood. Wood comes from trees, and trees are plants. Vegetables and fruit are plants too, and we eat a lot of them. So can we also eat wood and paper? Scientists say, "All food comes in some way from plants." Well, is that true? Animals eat grass and grow fat. Then we eat their meat. Little fish eat little sea plants; then bigger fish swim along and eat them. Chickens eat bits of grass and give us meat. Think for a minute. What food does not come from plants in some way? Scientists can do wonderful things with plants. They can make food just like meat and cheese. And they can make it without the help of animals. Now they have begun to say, "We make our paper from wood. We can also make food from wood. The next thing is not very difficult." What is the next thing? Perhaps it is food from paper. Scientists say, "We can turn paper into food. It will be good, cheap food too; cheaper than meat or fish or eggs." So please keep your old books and letters. Don't feed them to your cat. One day, soon they will be on your plate. _ . By saying "There is nothing like a good story for breakfast", what does the writer mean?

As children grow up, they become curious about different kinds of things. When they are babies, they are interested in the parts of their bodies and in the smiles of their mothers. The they become interested in the physical world around them: the plants, the animals, the sky. Later, they become interested in the things that people have made: wheels, bicycles, cars. And when they are adults, their curiosity continues. Sometimes this curiosity leads to a career (, ) in science. Scientists spend their lives trying to find out about the world. Those who work with the earth sciences study the earth, the oceans, and the skies. Other scientists who study living things work with the biological sciences. A third group of scientists study the physical sciences, e. g. physics, chemistry . These scientists have already discovered a lot about our world. For example, they tell us why your heart beats fast when you run. They say that when you are quiet, your heart normally beats sixty-five or seventy-five times a minute. Your heart is a pump that pumps blood to all parts of the body. The blood carries oxygen and nutrition. When you run, your muscles work very hard and use the nutrition that the blood carries to them. The muscles need oxygen, too . So your brain sends a signal to the heart. The signal means that the muscles need more nutrition and oxygen. Then the heart beats fast and sends blood quickly to the muscles. It may beat 90 to 140 times a minute. Of course, scientists cannot answer all of our questions. If we ask, "Why does the ocean water taste salty?" Scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into cracks. The rain then carries the salt into the earth and into the rivers. The rivers carry the salt into the ocean. But then we ask , "What happens to the salt in the ocean? The ocean does not get saltier every year." Scientists are not sure about the answer to this question. We know a lot about our world, but there are still many answers that we do not have, and we are curious. Scientists who work with the biological sciences study _ .

My husband and I both work from home.We have four children, so the times when I am alone in the house are few and far between.Like many work-at-home moms, when I do get a chance to be by myself ,I do something, whether it's related to my career or taking care of the household chores . One Thursday,things really came to a head.My husband was heading out to the gym,just thinking that I had nothing to do but watch the twins.My older boys were making plans with their friends without bothering me and they were expecting me to drive them there.The twins,being young,wanted my undivided attention.Even my customers seemed to be demanding that day.They sounded not satisfied with the products and wanted to cut down the prices more.Nobody bothered to ask if I might have plans of my own.But the truth was, I seldom did have any plans for myself, and everyone knew it. I always put their needs before my own.They took advantage of that. The next day,when the kids were at school, I headed for the movie theater--alone.I'd never been to the movies alone before.Would I look pitiful going to the theater by myself? Was I being silly by seeing a movie when so much work awaited me at home? I forced myself to take back these thoughts.And then I walked into the theater with my head held high and enjoyed every minute of the movie.For a couple of hours, I was nobody's wife or mother.I was just myself. From that point on,I decided that Fridays would be mine,at least for a couple of hours.Some Fridays, I head for the beach with a good book.Other Fridays, I go shopping.I really look forward to my Fridays after a long week of caring for my family. By forcing myself to slow down and put the needs of my family out of my mind, I feel closer to myself.I'm not completely responsible for caring for my family.I don't need to do it all myself. I just need to remember to spare some time to be with myself. How did the writer feel before she entered the cinema?

For many workers trying to lose weight, the weekend is a chance to do some exercise and eat something healthier than a supermarket sandwich at their desk. But some slimmers take a slightly different approach -- consuming more than half their weekly calorie intake from Friday night to Sunday. Away from the daily routine at work that helps them keep control of what they eat, they are snacking and drinking their way to a shocking 10,000 calories, a survey has found. Almost three-quarters of people trying to lose weight admit to over-eating at the weekend. A meal with friends or family, complete with alcohol, as well as a late-night snack before bed, can lead to adults consuming up to 3,500 calories in one day, a survey found. Men typically need 2,500 calories a day and women 2,000 calories. Consuming this amount would see men and women get through half their weekly calorie intake over the course of a 'bad' weekend. Women were found to eat less on a Sunday because of guilt over their consumption over the previous two days. Men had fewer doubts about a third day of excess. The biggest weekend diet danger comes from snacking between meals, the survey found. Some say they will often spend Saturday night in front of the TV with their families -- combining watching their favorite shows with crisps and biscuits. And seven in ten people admitted to having fattening takeaways at weekends, with pizza the most popular. Alcohol is another big factor in weekend bingeing.Around 70 percent still like to have a roast on a Sunday or a big meal with family or friends and a third of those will have second helpings. A spokesman from Forza Supplements, the diet company that conducted the survey, said, "We all have bad weekends where we have a lot of fun, but dieting goes out of the window." The 5:2 diet is becoming increasingly popular -- where we limit our calories for five days and allow ourselves a few treats on the other two days. "For many people, the two days off are Saturday and Sunday but they go way too far" Which kind of weekend diet does the greatest harm?

As a boy, Sanders was much influenced by books about the sea, but by the age of fifteen he had decided to become a doctor rather than a sailor. His father was a doctor. So he was often with the doctors and got along very well with them. When he was fourteen, he was already hanging around the hospital where he was supposed to be helping to clean the medicine bottles, but was actually trying to listen to the doctors' conversations with patients in the next room. During the war Sanders served in the army as a surgeon . "That was the happiest time of my life. I was dealing with real sufferers and on the whole making a success of my job." In Rhodes he taught the country people simple facts about medicine. He saw himself as a life-saver. He had proved his skill to himself and had a firm belief that he could serve those who lived simply, and were dependent upon him. Thus, while in a position to tell them what to do he could feel he was serving them. After the war, he married and set up a practice deep in the English countryside, working under an old doctor who hated the sight of blood. This gave the younger man plenty of opportunity to go on working as a life-saver. Having proved his skill to himself, Sanders _ .

*New labels to show calories The US government ruled that all food establishments should put the calorie information of their foods on their menus. Within a year chain restaurants, like fast food KFC, will have to say clearly on their menus how many calories their fried chicken wings, fries, and other items contain. Amusement parks, movie theaters and supermarkets will also have to follow the rules. The move is designed to fight against the problem of obesity in the US. * _ leading to world problem The entire world is facing this problem: antibiotic resistance. And the resistance will lead to the deaths of 10 million people across the world by 2025, predicted a new report released by the UK government. Antibiotics are used to destroy or slow the growth of harmful bacteria in our bodies. But overuse and misuse of them can encourage bacteria to develop new ways of overcoming antibiotics, which makes it increasingly difficult for humans to fight diseases. * _ Australia is the world's most expensive destination for international students, according to a study done by Hong Kong and Shanghai Banking Corporation (HSBC). They have to spend an average of $ 42,000 ( about 258 ,000 yuan) a year to study at Australian universities. Singapore is not far behind, with an average yearly cost of $ 39,229, followed by the US at $ 36,564 and the UK at 35,045. However, Australia's education quality only ranks joint fourth with Canada, well below the US, the UK, and Germany. In addition, international students studying in Germany only have to pay about one-sixth the cost of studying in Australia. * New Games sports may be added The International Olympic Committee has canceled the 28-sportcap for future summer Olympics But each summer Games will still only be allowed 10, 500 athletes and 310 events. Countries that could host the games will discuss plans with the committee during a new invitation stage before bidding.

Malnutrition remains a serious problem for India. But a new study shows that India's leading causes of death now also include diseases related to obesity such as heart disease. India's National Family Health Survey shows that more than twenty percent of Indians living in cities are overweight or obese. And in the northwestern state of Punjab, that is true for almost forty percent of women. Aradhna Tripathi is a business professional in New Delhi. She said, " Eating is the most important thing in any Indian household and how you show your love and gratitude for a person is through the kind of food you serve him. And the kind of lifestyle we are leading is one of the reasons why we have the number of obese people increasing every day. But Aradhna Tripathi says she has decided to lose weight. Her mother and grandmother are also diabetic . In fact, the International Diabetes Federation says India is now the diabetes capital of the world. Researchers say Indians store more body fat per kilogram than Europeans. That means obese Indians are even more at the risk of diabetes than other people. Doctor Anoop Misra at Fortis Hospital in New Delhi says the risk of diabetes is crossing social and economic lines. _ But Doctor Misra is hopeful that the spread (,)of obesity can be slowed. And he says it must start in schools by giving all Indian children the same instruction on physical activity and diet. The World Health Organization says China is also moving up in obesity rates. The estimate has reached about five percent countryside and as high as twenty percent in some cities. According to Aradhna Tripathi , one of the causes of the obesity problems is _ .

There have always been a lot of commonly believed but exercise. Some people believe that they can't help putting on hold that if they stop exercising, their muscles will turn into fat. Here are some more myths: false ideas about being fat and doing weight as they get older, while others I'll never lose weightI come from a fat family Wrong! While we can't change the body type we are bom with, we can't blame our genes for making us fat. There's plenty of evidence that fatness runs in families, and the main reason is that they share the same habits of eating too much and exercising too little. I am fat because I burn calories slowly Wrong! Fatness is not caused by a slow metabolism . In fact, although fat people consume more energy than slim people,they also fail to realize how much they eat! Keeping a diary can help you work out your daily food intake more accurately. Exercise is boring Wrong! Anything will become boring if you do it repetitively. The key is to develop a balanced and varied program thafs fun as well as progressive. If you enjoy a Sunday walk,take a different route. If you do yoga,try a tai chi class. If you like swimming, set yourself a distance or time challenge. No pain, no gain Wrong! Exercise is not meant to hurt. Indeed, pain is your body telling you something's wrong, and continuing to exercise could lead to serious injury. You may experience mild discomfort as you begin to exercise regularly, but this is your body adapting to the positive changes in your lifestyle and the aches should disappear relatively quickly. If they don't, rest and seek medical advice. What is the purpose of the passage?

About influenza A(H7N9) virus What is the influenza A(H7N9) virus? Influenza A H7 viruses are a group of influenza viruses that normally spread among birds. The influenza A(H7N9) virus is one smaller group among the larger group of H7 viruses. Although some H7 viruses (H7N2, H7N3 and H7N7) have sometimes been found to infect humans, no human infections with H7N9 viruses have been reported until recent reports from China. What are the main signs of human infection with influenza A(H7N9) virus? So far, most patients with this infection have had severe pneumonia . Signs include fever, cough and shortness of breath. However, information is still limited about the full area of disease that infection with influenza A(H7N9) virus might cause. How did people become infected with the influenza A(H7N9) virus? Some of the confirmed cases had connections with animals or with an animal environment. The virus has been found in a pigeon in a market in Shanghai. It is not yet known how persons became infected. The possibility of animal-to-human spread is being looked into. Is it safe to eat meat like chicken and pork products? Influenza viruses are not spread through eating well-cooked food. Because influenza viruses are made inactive by normal temperatures used for cooking (so that food reaches 70degC in all parts), it is safe to eat properly prepared and cooked meat. Diseased animals and animals that have died of diseases should not be eaten. In areas experiencing outbreaks, meat products can be safely eaten only if they are properly cooked and properly handled during food preparation. The eating of raw meat and uncooked blood-based dishes is a high-risk practice and should be discouraged. Is it safe to travel to China? The number of confirmed cases in China is very low. WHO does not advise the application of any travel measures with respect to visitors to China, nor to persons leaving China. Are Chinese products safe? There is no evidence to link the present cases with any Chinese products. WHO advises that people should not fear to trade them at this time. According to this passage the way of spreading the influenza A(H7N9) virus is _ .

It is well known that the examination system we are now using may be a good way of testing a student's memory, but it can tell you nothing about a student's ability. It does no good to students and teachers. As soon as a child begins school, he enters a world of examination that will decide his future of job. In fact a good examination system should train a student to think for himself. But it now does nothing about that. So students are encouraged to member what is taught. It does not enable them to gain more and note knowledge. The students who come out first in the examination often may not be the best in their studies. Besides, the examinations often force teachers to train students what to do with the coming examination from time to time. There must be some simpler and better way to test a student' s ability besides knowledge. And that is what we should do at once. The passage tells us about the importance of _ .

Every so often, birds, just like humans, do what it takes to feel really, really good. The bird version is to sit on an anthill so that hundreds of ants climb all over their bodies, or even better, some birds pick up mouthfuls of pressed ants and rub themselves all over. Afterwards, the birds either eat the ants or set them free. Scientists call this "anting." It's a common bird practice, and is especially done by the smarter birds. Ravens do it. Magpies do it. However, birds aren't the only animals that use anting --- squirrels, cats, and hedgehogs have all been observed doing the same sort of thing! Why birds "ant" is something of a mystery, but one thought is acceptable. Ants have defensive secretions , chemical weapons they use to fight off other insects and bacteria. So pressed ants help the birds drive the insects away. Similarly, if you cover your body with them, you can move through the forest without worrying about being bitten by insects. Plus, ants are cheap. They are around. However, we have a better explanation. Birds "ant" a lot in spring and summer. For many birds, that's the season for birds to change feathers. So maybe ant secretions are like bath oil; they comfort the skin during feather replacement. A British scientist once declared "the purpose of anting the stimulation and comfort of the body," and that the general effect "is similar to that gained by man from the use of outside stimulants, and perhaps also smoking." And like cigarettes, anting can become a habit. Another study compares anting to "the human habits of smoking and drug taking," and says, "it is enjoyed for the feeling of excitement it results in. So once experienced, it is difficult to stop." That's why you often see mother birds shouting at their babies who come near their first anthill. "Stay away from there, child... Don't touch those ants!" they cry. I don't speak Raven. Or Magpie. But I have been a parent. So some things I know. It is implied in the text that _ .

More students than ever before are taking a gap-year before going to university.It used to be called the "year off" between school and university.The gap-year phenomenon originated with the months left over to Oxbridge applicants between entrance exams in November and the start of the next academic year. This year, 25,310 students who have accepted places in higher education institutions have put off their entry until next year, according to statistics on university entrance provided by University and College Admissions Serbice(UCAS). That is a record 14.7% increase in the number of students taking a gap year. Tony Higgins from UCAS said that the statistics are good news for everyone in higher education. "Students who take a well-planned year out are more likely to be stisfied with, and complete, their chosen course. Students who take a gap year are often more mature and responsible," he said. But not everyone is happy. Owain James, the president of the National Union of Students(NUS), argued that the increase is evidence of student hadship - young people are being forced into earning money before finishing their education. "New students are now aware that they are likely to leave university up to PS15,000 in debt. It is not surprising that more and More students are taking a gap year to earn money to support their study for the degree.NUS statistics show that over 40% of students are forced to work during term time and the figure increases to 90% during vacation periods,"he said. What would most students do on their vacation according to NUS statistics?

At Dallas/Fort Worth Airport, the lights are controlled by sensors that measure sunlight. They dim immediately when it's sunny and brighten when a passing cloud blocks the sun. A wall of windows at a University of Pennsylvania engineering building has built-in blinds controlled by a computer program that follows the sun's path. Buildings are getting smarter and the next generation of building materials is expected to do even more. Windows could catch the sun's energy to heat water. Sensors that measure the carbon dioxide breathed out by people in a room could determine whether the air conditioning needs to be turned up. Many new materials and technology have been designed in the last 15 years. They are now being used in a wave of buildings designed to save as much energy as possible. They include old ideas, like "green roofs", where a belt of plants on a roof helps the building keep heat in winter and stay cool in summer, and new ideas, like special coating for windows that lets light in, but keeps heat out. As technologies such as sensors become cheaper, their uses spread. The elevators at Seven World Trade Center, which is under construction in New York, use a system that groups people traveling to nearby floors into the same elevator, thus saving elevator stops. People who work in the building will enter it by swiping ID cards that will tell the elevators their floor, readouts will then tell them which elevator to use. The building also has windows with a coating that blocks heat while letting in light. More new building materials and technology are in development. A Philadelphia building firm is now working on "smart wrap" that uses tiny solar collectors to catch the sun's energy and transmitters as wide as a human hair to move it. They are expected to change the face of the construction industry in the next ten years or so. What might be the most suitable title for the text?

Healthy eating starts with learning new ways to eat,such as adding more fresh fruit and vegetables,and _ foods that have lots of fat, salt and sugar. Healthy eating will help you feel your best and give you plenty of energy.It can help you deal with stress better. However,healthy eating isn't a diet . If you eat too little when you diet, you may eat more after you stop dieting. Eating a healthy, balanced diet is very satisfying. And if you match that with more exercise, you may be able to have a healthier weight. What can you do to make healthy eating habit? First, think about your reasons for heathier eating. Do you want to improve your health?Do you want to feel better? Next, think about small changes that you can make. Then set some goals and go for them. Set an easy goal you can reach.,like having a piece of fruit each day. Set a long-term goal too, such as having one meal not including meat or fish every week.What's more, having help from others is important . After you get more help, it'll be easier for you to make changes. Have family and friends help you make meals and give you useful advice on healthy cooking . If you need more help, talk to your doctor or look online for groups that care about healthy eating and tell success stories . The writer mentions people can get help from the following EXCEPT

By Zhang Youlv (China Daily 09/29/2008)--A manned lunar landing is China's next target when the current three-stage space program ends in the next dacade. "When our manned space program is completed, we will travel even further," Wang Zhaoyao, deputy head of China's manned space program office and Shenzhou VII mission spokesman, told a briefing in Beijing three hours after China's third manned space mission was successfully concluded yesterday. "After comprehensively analyzing the general trend of the international development of manned space, as well as realities in China, we see a manned lunar landing as a both challenging and tactical field in global hi-tech," he said. "We believe it necessary for our country to do something in this field," Wang said. He did not give a specific date for a moon landing. Wang, however, said, "Experts believe this is 'very much needed' for research into relevant (closely connected) technologies to further China's achievements in space." The 68-hour Shenzhou VII mission featured a 25-minute spacewalk on Saturday. It was broadcast live and watched by millions throughout the country. The crew's landing at a site in the Inner Mongolia autonomous region was also carried live by national television. The entire mission was pronounced a complete success. Wang said the three astronauts, were transported to Hohhot, the region's capital, and would spend the evening there. "They will return to Beijing this morning," he said. "During the course of the mission, Russian experts provided strong technical support for the EVA spacesuits. The successful Sino-Russian cooperation for this flight created beneficial conditions for more intensive cooperation between the two sides in the future," Wang said. The mission's success has paved the way for completing the second stage of the program--building a space station before 2020. Before that, a space lab will be set up in 2010 with Shenzhou X, the country's next full-crew space journey. What would be the best title for this passage?

It is reported that conservation groups in North America have been arguing about the benefits and dangers of wolves. Some groups believe wolves should be killed. Other people believe wolves must be protected so that they will not disappear from the wilderness For Killing Wolves In Alaska,the wolf almost disappeared a few years ago,because hunters were killing hundreds of them for sport. However.1aws were established to protect the wolves from sportsmen and people who catch the animals for their fur.So the wolf population has greatly increased. Now there are so many wolves that they are destroying their own food supply. A wolf naturally eats animals in the deer family. People in the wilderness also hunt deer for food.Many of the animals have been destroyed by the very cold winters recently and by changes in the wilderness plant life.When the deer can't find enough food,they die. If the wolves continue to kill large numbers of deer,their prey will disappear some day.And the wolves will.too.So we must change the cycle of life in the wilderness to balance the ecology.If we killed more wolves,we would save them and their prey from dying out.We'd also save some farm animals. In another northern state,wolves attack cows and chickens for food.Farmers want the government to send biologists to study the problem.They believe it necessary to kill wolves in some areas and to protect them in places where there is a small wolf population. Against Killing Wolves If you had lived long ago,you would have heard many different stories about the dangerous wolf.According to most stories,hungry wolves often kill people for food.Even today,the stories of the "big bad wolf'"will not disappear. But the fact is wolves are afraid of people.and they seldom travel in areas where there is a human smell.When wolves eat other animals,they usually kill the very young.or the sick and injured .The strongest survive .No kind of animal would have survived through the centuries if the weak members had lived.And has always been a law of nature. Although some people say it is good sense to kill wolves,we say it is nonsense! Researchers have found wolves and their prey living in balance.The wolves keep the deer population from becoming too large, and that keeps a balance in the wilderness plant life. The real problem is that the areas where wolves can live are being used by people.Even if wilderness land is not used directly for human needs.the wolves can't always find enough food .So they travel to the nearest source, which is often a farm.Then there is danger.The "big bad wolf" has arrived! And everyone knows what happens next. According to those against killing wolves,when wolves eat other animals, _ .

Friends are very important in our everyday life. Everyone needs friends. We all like to feel close to someone. It is nice to have a friend to talk, laugh and do things with. Certainly, sometimes we need to be alone. We don't always want people around. But we would feel lonely if we never had a friend. No two people are just the same. Friends sometimes don't get on well. That doesn't mean that they no longer like each other. Most of the time they will make it up and become friends again. Sometimes friends move away. Then we feel very sad. We miss them very much but we can call them or write to them. We can also make new friends. It is encouraging to find out how much we like new people when we get to know them. There's more good news for people who have friends. They live longer than people who don't. Why? Friends can make us feel happy. Being happy helps you stay well.

Death is natural, but do you have any idea of the process of dying? Modern scientists divide the process of dying into two phases --- clinical or temporary death and biological death. Clinical death occurs when the vital organs, such as the heart or lungs, have ceased to function, but have not suffered permanent damage. The organism can still be revived . Biological death occurs when changes in the organism lead to the "breaking up" of vital cells and tissues. Death is then unchangeable and final. Scientists have been seeking a way to prolong the period of clinical death so that the organism can remain alive before biological death occurs. The best method developed so far involves cooling of the organism, combined with narcotic sleep. By slowing down the body's metabolism , cooling delays the processes leading to biological death. To illustrate how this works, scientists performed an experiment on a six-year-old female monkey called Keta. The scientist put Keta to sleep with a narcotic. Then they surrounded her body with ice-bags and began checking her body temperature. When it had dropped to 28 degrees the scientists began draining blood from an artery. The monkey's blood pressure decreased and an hour later both the heart and breathing stopped: clinical death set in. For twenty minutes Keta remained in this state. Her temperature dropped to 22 degrees. At this point the scientists pumped blood into an artery in the direction of the heart and started artificial breathing. After two minutes Keta's heart became active once more. After fifteen minutes, spontaneous breathing began, and after four hours Keta opened her eyes and lifted her head. After six hours, when the scientists tried to give her a penicillin injection, Keta seized the syringe and ran with it around the room. Her behavior differed little from that of a healthy animal. How did the scientists put Keta into clinical death?

What if you arrived home to find a delicious hot meal waiting for you,prepared by your very own kitchen robot? It might sound like science fiction,but professors at the university of Tokyo have taken the first steps toward making that scenario a reality.The team recently introduced a humanoid kitchen robot that can pour tea and other drinks into cups and serve them to guests.When teatime is over,the robot can also wash the dishes and put them away. In California,another interesting kitchen robot has been developed.Called the Readybot,it can pick up objects and either store them in cabinets or put them in the trash.It also carries a separate floor-cleaning robot that can operate by itself.Unlike the Japanese robot,Readybot is not humanoid.Instead,it looks more like a large box with arms and wheels. Readybot was created by engineers and designers who established a club called the Readybot Challenge.They believe that in the future millions of robots will be needed in homes to perform ordinary household tasks.Readybot is just the first step in their plan to create a robot that can tackle jobs not only in kitchens but in other rooms of homes and in offices as well. Clearly there are technological hurdles to overcome before robots can cook a complete dinner,and there are also many safety concerns.Not everyone(especially parents)would be comfortable with the idea of robots in their house,manipulating hot pans and sharp knives.The European Commission recently funded a project to study these concerns. What does the writer imply about the Japanese robot?

"Drink your milk. It's good for you!" You've probably heard that many times, and it's true. Milk contains calcium , which is necessary for keeping bones and teeth healthy and strong. The US government even requires milk as part of the National School Lunch Program, saying that students should drink one cup of fat-free or low-fat milk every meal. However, a group of doctors asked the government to take it away from the lunch program. The US 'Physician Committee for Responsible Medicine (PCRM) says, "Milk is high in sugar, fat and animal protein," all of which have negative effects on health. The PCRM says there are better and healthier ways to get calcium such as eating beans, broccoli, cereals and tofu. Orange juice and soymilk that have calcium added to them also supply the nutrient. "One of the only reasons people prefer milk is that it is going to help build strong bones," says Dr Neal Barnard, president of the PCRM. But milk may not be the best way to get calcium your body needs. Of course, calcium is important for healthy bones and teeth, but there are other things that affect your bone strength, such as genes, how much vitamin D you take in, and getting an hour's worth of exercise every day. Some people disagree with the idea that milk isn't important. Keri Gans, an American Dietitian, says "I don't think it's irresponsible to take this beverage that children enjoy it very much, especially among those who are unable to meet their nutrient needs for the day, and remove it from the lunch line." The U.S government is now considering the request of the PCRM, but a decision may be a long way off. Meanwhile, Marion Nestle, a professor puts it best: "Milk certainly has nutrients. Other food has the same nutrients. It's just food. As with other food, too much might be a problem." According to the author, _ .

What is the nature of the scientific attitude, the attitude of the man or woman who studies and applies physics, biology, chemistry, geology, engineering, medicine or any other science? We all know that science plays an important role in our societies. However, many people believe that our progress depends on two different aspects of science. The first aspect is the application of the machines, products and systems of knowledge that scientists and technologists develop. The second is the application of the special methods of thought and action that scientists use in their work. What are these special methods of thinking and acting? First of all, it seems that a successful scientist is curious - he wants to find out how and why the universe works. He usually pays attention to problems which he notices have no satisfying explanation, and looks for relationships even if the data available seem to be unconnected. Moreover, he thinks he can improve the existing conditions and enjoys trying to solve the problems which this involves. He is a good observer, accurate, patient and objective and uses the facts he observes to the fullest. For example, trained observers obtain a very large amount of information about a star mainly from the accurate analysis of the simple lines that appear in a spectrum . He does not accept statements which are not based on the most complete evidence available. He rejects authority as the only basis for truth. Scientists always check statements and make experiments carefully and objectively. Furthermore, he does not readily accept his own idea, since he knows that man is the least reliable of scientific instruments and that a number of factors tend to disturb objective investigation. Lastly, he is full of imagination since he often has to look for relationships in data which are not only complex but also frequently incomplete. Furthermore, he needs imagination if he wants to guess how processes work and how events take place. These seem to be some of the ways in which a successful scientist or technologist thinks and acts. Which word can be used to describe the data that a good scientist uses?

Spending more than two hours a night doing homework leads to better results in English,math and science, according to a major study (by Pam Sammons, England) which has tracked the progress of3,000 children over the past 15 years. Spending any time doing homework showed advantages, but the influence was greater for the students who put in two to three hours a night, according to the study published by the Department for Education in England. The scientists who did the research say their study empbasizes what students actually do rather than how much work the school has set. Pam Sammons, a professor of education at Oxford University, said that time spent on homework showed the influence of the school-if children were expected to do homework and if they enjoy their subjects. "That's one of the reasons Indian and Chinese children do better.They put more time in it." he added. It's also reported that students who enjoyed school got better results. "Schools could make sure children had a better experience by improving the school environment, making school work interesting and making children feel supported by teachers." Sammons said. It is suggested that children aged 5 t0 7 should be set one-hour homework a week, half an hour a night for 7 t0 11-year-olds. Secondary schools were encouraged to set up two hours a night for 14 t0 16-year-olds. "Head teachers should make their own homework policy ," the government says.

Kids love the all-knowing Google. Your kids likely use Google to help them find everything from information for homework assignments, to funny cat videos, and everything in between. Sometimes kids can take a "wrong turn" on Google and end up in a dark part of the Internet where they shouldn't be. Thankfully, Google has some parental control features that parents can implement to at least help reduce the volume of crap that ends up in search results,which can enable you to help keep your curious kids from ending up on the wrong side of the tracks. What is Google SafeSearch? Google SafeSearch is one of the primary parental control options offered by Google to help parents police search results. SafeSearch helps to filter explicit content out of search results. It is mainly designed to target sexually explicit material (images and videos) and not violent content. How to Enable Google SafeSearch?1. From the "Search Settings" preferences page, place a check in the box with the label "Filter explicit results". 2. To lock this setting so that your child can't change it, click the "Lock SafeSearch" link. If you are not already logged into your Google account, you will need to do so in order to lock SafeSearch to the "on" position. Enable SafeSearch on Mobile Devices. In addition to your computer, you will probably also want to enable SafeSearch on any mobile device that your child uses regularly. For instructions on how to enable SafeSearch on a variety of mobile devices, check out Google's SafeSearch Mobile support page. As we all know, kids are going to be kids and try to test their boundaries. We put up one roadblock and they go around it. It's a constant cat and mouse game and there will always be some internet door that we as parents forget to lock, and that will be the one that the kids get through, but we do the best we can. What's the first thing you'd do before setting Google SafeSearch?

Who knows why kids do anything? When it comes to cyberbullying , they are often motivated by anger or frustration . Sometimes they do it for entertainment or because they are bored and have too much time on their hands and too many tech toys available to them. Many do it for laughs or to get a reaction. Some do it by accident, without thinking before they do something. The power-hungry do it to make others suffer. And some think they are righting wrong and standing up for others. Because their motives differ, the solutions and responses to each type of cyberbullying incident has to differ, too. There is no "one size fits all" when cyberbullying is concerned. However, education can help considerably in preventing and dealing with the consequences of cyberbullying. If we can help kids understand how much bullying hurts, and how in many cases words can hurt, fewer may cooperate with the cyberbullies. They will think twice before forwarding a hurtful e-mail, or visiting a cyberbullying "vote for the fat girl" site, or allowing others to take videos or cell phone pictures of personal moments. And, in addition to not lending their efforts to continue the cyberbullying, we also need to teach our children not to stand silently by while others are being hurt. Martin Luther King, Jr. once said that in the end we will remember not the words of our enemies, but the silence of our friends. Kids will feel more comfortable to break the silence if given an anonymous method of reporting cyberbullying web-sites. School administration, community groups and even school policing staff can receive these anonymous tips and take action quickly. If our children do not allow the cyberbullies to use them to embarrass or hurt others and realize that silence, when others are being hurt, is not acceptable, cyberbullying will quickly stop. It's a tall task, but a noble goal. And in the end, our children will be safer online and offline. We will have helped create a generation of good cybercitizens, controlling the technology instead of being controlled by it. The writer organizes the passage following the pattern of _ .

winter-swimming has become popular in Beijing. three years ago, few people would go swimming in the city waters. but now there is a winter-swimming enthusiasts'club and it has more than 2,000 members. the oldest is 84 years of age and the youngest is only 7. _ They may be workers, peasants, soldiers, teachers, students....Though it is now the coldest part of the season and the water temperature in the city's lakes is around 0degc, many winter-simmers still swim in the icy waters, even when it is snowing. They enjoy themselves in the lake, while the people by the side of the lake are wearing heavy clothes. why are so many people interested in winter-swimming? Because winter-swimming can be good for one's health. Bei Sha is a good example. He is 69 years old, and he once suffered from heart trouble for 26 years.

Guide dogs help blind people who cannot get around by themselves.Although Yorkshire terriers and poodles are good companion dogs,guide dogs are chosen from lager breeds such as German shepherds,golden retrievers,and Labrador retrievers.The young dogs are raised by families until they are eighteen months old.During this time,they get lots of love and attention,but they are also taught to obey.Then the dogs go to a special school where,for four months,they work with a sighted trainer,an individual who can see.The dog forms a close relationship with this person who teaches it how to follow directions such as right,left,straight ahead,and stop.The young dog also learns to watch out for dangerous traffic and wait until it is safe to cross a busy street. When the dog is two years old,it starts training with the blind person it will live with. The dog and its new owner make many trips from downtown to where the blind person lives so the dog becomes familiar with the normal atmosphere.During the training,a sighted trainer always remains with them. A blind person who is getting a guide dog for the first time will train for about a month. If the individual has had a dog before,the training takes about three weeks.After the training,the blind person depends on the guide dog for between seven and twelve years.At that point,the working dog become a family pet and the owner needs to train with a younger guide dog. What's this passage mainly about?

Remember, from the moment they are born, our children have the ability to know when they are hungry - and they cry to let us know too! Of course, they also cry to let us know they are wet, hurt, or bored, but we soon learn to tell the difference and try to meet each need somehow. When we begin to feed them solid foods, they let us know when they have had enough by turning away from the spoon - or refusing the food back at us! Why is it that once children are old enough to sit at the table their parents are often heard bargaining with them or threatening them to finish all their dinner? When we make our children eat up the plate that we filled, we don't pay attention to their born ability to know how much, and what, their bodies need. Instead, we should allow them to use their own hunger feelings to determine how much they need, while we provide a balance of nutritious and "fun" foods. When we teach them about moderation and set a great example by living an active, healthy lifestyle, they will be less likely to develop weight problems later in life. Think of your slim friend who eats whatever she wants -but will refuse ice cream if she has had enough to eat! "Eat all your dinner if you want dessert" translates to "you must overeat so I will reward you by letting you overeat some more!" By using sweets as a reward for good behavior, kids begin to believe sweets are really special and they may want them even more. Instead, by making dessert just another (small) part of an enjoyable meal, kids learn to "save room for dessert" instead of becoming a member of the "clean plate club." Children are born to know _ .

Each of us can live strong,healthy,energetic lives for a long time to come.The key?Actually,there are many of them. Eat fewer calories,but more food Slimming down can help prevent disease,and cutting way back on the amount you eat may even slow the aging process.When nutrition researchers invited themselves over for dinner in kitchens across the globe-from Greece to Japan to the state of Pennsylvania--they discovered a stomach-satisfying secret to good health:Pile your plate high with vegetables and fruits,add respectable parts of beans and whole grains,and ignore high-calorie food like cheeseburgers,cream sauces,and fatty meats. Use exercise as an anti-aging vaccine Exercise can help you gain a better quality of life as you age.It's no secret that physical activity strengthens muscles,burn calories,and puts a happy bounce in your step.But recently,researchers discovered a new,extra benefit:Exercise acts as a powerful way against the aging process itself. When exercise physiologists put healthy people aged 60 to 85 on Weight-training programs for six months then tested them for signs of free-radical damage,they were surprised by the results.By the end of the study,low-intensity exercisers had a drop in free-radical damage,while high-intensity exercisers had a slight increase. Find something interesting to do Life is always busy no matter what your age.But the truth is,when people are retired,time usually does become more available for adults after 60.With this time come choices.The easy one is merely to relax:watch more TV,eat out more often,talk on the phone as much as you want.The better choice? Discover something more meaningful to devote yourself to and do it wholeheartedly. The new discovery of exercise probably is that _ .

Jamie Oliver, a lively Britain guy, loves to share his secrets. In his first television show,The Naked Chef, Oliver taught everyone to make simple but delicious food. In Jamie's Kitchen, he taught young people how to prepare meals. His next show,Jamie's School Dinners, is about changing the food that students eat. Oliver saw that some schools in Britain were serving junk food--food that is easy to eat but unhealthy. Although it can be delicious, junk food is not very good for children. It is sometimes bad for their health, because it doesn't give them the energy they need at school. They sometimes can't think well or feel down, and they sometimes put on weight. Some of the junk food that Oliver wants to change is canned spaghetti, chicken nuggets, French fries, soda, and muffins. He encourages schools to serve fresh and health meats, vegetables and fruits. He helps the school cooks to make healthy dinners without junk food. People liked Oliver's idea of bringing quality food to schools. Thousands enjoyed his television show. But Oliver wanted them to do more than just watch. At hisFeed Me Betterwebsites, he collected over 270,000 signatures from people. Oliver sent these signatures to British Prime Minister Tony Blair. Then Blair promised to help change the school kitchens, teach school cooks to make healthy food, and spend more on school dinners. Thanks to Jamie Oliver, my children will be able to enjoy more healthy meals at school. Which of the following may Oliver like best?

Weather has a strong effect on people. It influences health, intelligence and feelings. In August, it is very hot and wet in the southern part of the United States. People there easily have heart trouble and other kinds of health problems during this month. In the Northeast and the Middle West, it is hot at some times and very cold at other times. People in those states will have heart trouble after the weather changes in February or March. The weather can also influence intelligence. For example, in a 1983 study by scientists, the IQ scores of some college students were very high during storm, but after the storm, their scores were low. Storms can increase intelligence. Very hot weather, on the other hand, can decrease it. Students in many schools of the United States often do badly in exams in the hot months of the year(July and August). Weather also has a strong effect on people's feeling. Winter may be a bad time for thin people. They usually feel cold during these months. They might feel depressed during cold weather. In hot summer weather, on the other hand, fat people may feel unhappy. At about 65F, people become stronger. Low air pressure makes people feel free, but it also increases forgetful- ness. People leave more bags and umbrellas on buses and in stores on low pressure days. There is a"perfect weather"for work and health. People feel best at a tempera- ture of about 64F with 65 percent humidity . Are you feeling sick, sad, tired, forgetful, or very intelligent today? The weather may be the reason.

We all enjoy the beautiful show of color1s as leaves change each autumn. But did you ever wonder how and why this happens? To answer the question, first you have to understand what leaves are and what they do. Leaves are nature's food factories. Plants take water from the ground through their roots. And they take a gas called carbon dioxide from the air. Plants use sunlight to turn water and carbon dioxide into glucose . Glucose is a kind of sugar. Plants use glucose as food for energy and as a building block for growing. The way plants turn water and carbon dioxide into sugar is called photosynthesis . That means, "putting together with light". A chemical called chlorophyll helps photosynthesis. Chlorophyll is what gives plants their green color1. As summer ends and autumn comes, the days get shorter and shorter. This is how trees "know" to begin getting ready for winter. During winter, there is not enough light or water for photosynthesis. Trees rest during this time and live off the food they stored during the summer. They begin to shut down their food-making factories. The green chlorophyll disappears from the leaves. As the bright green fades away, we begin to see yellow and orange leaves. Small amounts of these color1s have been in the leaves all along. We just can't see them in the summer, because they are covered up by the green chlorophyll. The bright reds and yellows we see in leaves are made mostly in autumn. In some trees, like maples, glucose is caught in the leaves after photosynthesis stops. Sunlight and the cool nights of autumn turn this glucose into a red color1. The brown color1 of trees like oaks is made from waste left in the leaves. It is the mixture of all these things that makes the beautiful color1s we enjoy during autumn. From the text we can see that photosynthesis _ .

I may not be the wisest person on this planet.but I will tell you a little secret to happiness:Help other,,and live life.It is that simple.Just help a friend study for a test,or volunteer at a nursing home .I learned this after a long,hard search. I was feeling really down because my long4ime friend had died.Then I started a six-week volunteering at a nursing home all day every Saturday.My routine was to serve the meal and clean up.After that,I would wait for the head nurse to tell me what to do. One day I was told to go to Room 117 to make sure the patient was all right.In the room I found a boy of eight sitting in his bed watching a movie.I was shocked to see a child in this seemingly forgotten nursing home for the old.He was so small and weak that you had to look closely to find him.He motioned for me to sit down.I grabbed his medical chart from which later I found out he had a terminal illness. We started to talk,and I found out that his family rarely visited,and all he did ever7 day was watch TV.I wanted to cry for him,and for my lost friend.As we talked,he had a smile on his face,and I asked him why. "The entire two hours I've been here you've never lost that smile.With this horrible disease,how do you still manage to stay happy?" He thought for a moment,and then said that too many people are dead even before they die. They walk around feeling that God has cursed them and that they have nothing to live for. The boy said that he would not be like that.He wakes every morning thankful to see another sunrise.He keeps his window open so that he can smell the flowers and feel the heat of the sun.He also said that he has hope. "Too many people haven't seen much of that around here," he said," Life is full of hope and we need to live life before it is gone." I don't know what happened to him.I assume he passed away,but his lesson lives on.I now wake up and live each day to the fullest.The key to life is not money or fame,but the lessons we learn from it. The boy stayed happy mainly due to _ .

When Elizabeth Kenny was a little girl, she fell off a horse and hurt her arm. Mrs. Kenny took her to a doctor in Toowoomba, Queensland. In the doctor's, Elizabeth saw many bottles of medicine standing in a row. Since then, she wanted to be a nurse. As soon as she was old enough, Elizabeth was trained in a hospital. After working for some time, she made a surprising discovery. Among her patients were some children who had lost the use of their legs because of polio ( ) . Kenny tried putting hot cloth on their legs and washing them in a special way. The results were great. The children were able to use their legs again. Most doctors would not believe that children could get well in such a simple way. Gradually, however, she became famous. From 1993 on people from many parts of the world brought their children to Australia to receive treatment by this wonderful nurse. She was invited to America where her methods were used in many hospitals. Money was collected to build Kenny foundations which were for polio patients. Kenny died in 1952, but she will long be remembered for her fight against polio. The best title of the text is most likely to be _ .

They already guide blind and disabled people; now dogs are to be trained to help people with dementia or Alzheimer's.Alzheimer's can make people confuse night and day or forget basic things such as washing or drinking enough water. The dogs will be trained to respond to sound triggers in the home that cause them to perform tasks.The duties will include reminding their owners to take medicine, as well as encouraging them to eat, drink and sleep regularly. The idea was developed by design students at the Glasgow School of Art and will now be put into practice by Alzheimer's Scotland and Dogs for the Disabled.The first dogs will be distributed to four Scottish couples, where one of the partners is in the early stages of dementia.Some 670,000 people in Britain have dementia and one in three over 65s will develop the condition.By 2021 this is expected to rise to one million. Joyce Gray of Alzheimer's Scotland said, "People in the early stages of dementia are still able to live a relatively normal life, and dogs help to maintain routine." Another advantage of using the pets as companions is that dogs can give them a sense of silent support and companionship.Ms Gray said, "The evidence is that people may forget familiar faces but not pets.It's such a strong bond that people often remember _ longest.People don't need to communicate verbally but they can still interact.You can have a speechless bond." Helen McCain, director of Dogs for the Disabled, said, "People with dementia often forget to take the medicine.If a dog presents them with a bag with pills in it there's a greater chance of them taking it.The dog would also encourage the owner to take them out for walks, ensuring they keep exercising and interacting with other people."

It is easier to float in the ocean than it is to float in a swimming pool. Do you know why? Ocean water is full of salt-- and salt water can hold up more weigh than fresh water. See for yourself! You Will Need: * 3 cups of warm water * Measuring cup * Wide-mouthed jar * Salt * Spoon * Raw potato You Will Do: Pour 1.5 cups of warm water into the jar.Add 1/3 cup of salt.Stir until the salt is completely dissolved.Add another 1.5 cups of water. Pour it slowly over the back of the spoon into the jar so that the two liquid will not mix together. Gently place the potato into the jar. Do not drop it. What Will Happen: The potato will sink-- but only halfway! Why? Salt water is heavier than fresh water, so it will stay on the bottom. The fresh water will remain on top. The potato is heavier than the fresh water, but it is lighter than the salt water. That is why the potato will sink halfway down. In the experiment, what should you do right after you pour the water over the spoon?

A recent survey of 2000 parents in Britain showed that they are often afraid of science questions asked by their curious children only because they have no idea what the answer is. Here is a list of some simple questions that you can ask your parents to see if they know the answers. Q: Why is the sky blue? A: You probably know white sunlight is made up of seven colors. While it moves in a straight line when going through space, it starts to divide as it hits "raised area" in the atmosphere. The ones with longest wavelengths pass through easily. The blue , however , can be taken in by the gas molecules because it has a shorter wavelength , which in turn scatters it in different directions. That's why when you look up at the sky, it appears to be blue. Q:Why does the moon sometimes appear during the daytime? A: The simple answer to that is because just like any other object it is being lit by the sun. As long as it is around 45 degrees or even 90 degrees off the sun, it will receive light and be able to be seen. The only time it is not able to be seen during its 28-day orbit around the earth is when it is right between the earth and the sun. That's because its back , which is not lit by the sun, is facing us. Q: Where do birds/ honeybees go in winter? A: While the bird part is quite easy, since a lot of them get together and travel, the honeybee part is likely to puzzle your parents. It turns out that these busy insects stop being that active when the temperature drops below 50degF. Instead ,they get together in the lower central area of the hive and form a ball around their queen. This helps keep both warm enough to survive the cold winter months. What do honeybees choose to do when the temperature drops below 50degF?

A tender woman, or an independent one, which one would you prefer? Arecent research shows that most people would choose the latter. This type of woman is called a nuhanzi ("tough woman"). Experts believe these characteristics have social and psychological roots among young femalesin China. Su Hao's friends all call her a tough woman, because she can finish tough tasks usually carried out by men. For example, she carries 10-litre water to her dormitory on the 5th floor. "I depend on no one but myself," she says. According to a recent survey by China Youth Daily, tough women have become rather common in society. Of the 21,265 respondents, 78.5 percent said they are familiar with a tough woman. About 50 percent said they like women with tough characteristics, while less than 29 percent expressed the opposite view. Why are tough women gaining popularity? Shen Meng, a psychological consultant, believes the fierce competition in society is contributing to this trend. "Women are often in a disadvantaged position compared to men," Shen says. "In order to survive, they have to be independent, strong and tough." Liu Xiao lin, professor of psychology at Wuhan Mental Health Center, believes tough women are brought up this way. They are often on close relationship with their fathers, who teach their daughters to be brave and decisive," he says. As a result, these women are more likely to be psychologically healthy and more tolerant to stress, according to Liu. Though Liu believes that this is a good trend, Hu Shenzhi, a psychologist at the Guangdong Sunflower Counseling Center, says the popularity of tough woman indicates an unclear line between gender identities, which can lead to relationship problems. "Some women with characteristics that differ from the traditional female image may have a difficult time finding Mr Right," he says."Even if they get married, their manly characteristics might cause family conflicts. Why are there more tough women nowadays?

For some people, music is no fun at all. About 4% of the population is what scientists call "amusic". People who are amusic are born without the ability to enjoy musical notes. Amusic people often cannot tell the differences between two songs. As a result, songs sound like noise to an amusic. Many amuics compare the sound of music to pieces of metal hitting each other. Life can be hard for amusics. In fact, most people cannot begin to understand what it feels like to be an amusic. Just going to a restaurant or a shopping center can be uncomfortable or even painful. That is why many amusics have to stay away from places where there is music. However, this can result in social loneliness. "I used to hate parties," says Margaret, a seventy-year-old woman who only recently discovered that she was amusic. By studying people like Margaret, scientists are finally learning how to identify this unusual condition. Scientists say that the brains of amusics are different from those of people who can enjoy music. The difference is complex , and it is not connected with poor hearing. Amusics can understand other non-musical sounds well. They also have no problems understanding common speech. Scientists compare amusics to people who just can't see certain colors. Many amusics are happy when their condition is finally diagnosed . For years, Margaret felt embarrassed about her problem music. Now she knows that she is not alone. That makes it easier for her to explain. When people invite me to a concert, I just say "No, thanks. I'm amusic." says Margret. What causes amusics different from most people according to scientists?

In cities with rent control, the city government sets the maximum rent that a landlord can charge for an apartment. Supporters of rent control argue that it protects people who are living in apartment. Their rent cannot increase; therefore, they are not in danger of losing their homes. However, the critics say that after a long time, rent control may have negative effects. Landlords know that they cannot increase their profits. Therefore, they invest in other businesses where they can increase their profits. They do not invest in new buildings which would also be rent-controlled. As a result, new apartments are not built. Many people who need apartments cannot find any. According to the critics, the end result of rent control is a shortage of apartments in the city. Some experts argue that the minimum wage law can cause problems in the same way. The federal government sets the minimum that an employer must pay workers. The minimum helps people who generally look for unskilled, low-paying jobs. However, if the minimum is high, employers may hire fewer workers. They will replace workers with machinery. Therefore, other things being equal, the number of workers that employers want decreases. Thus, critics hold the opinion that an increase in the minimum wage may cause unemployment. Some poor people may find themselves without jobs instead of with jobs at the minimum wage. Supporters of the minimum wage say that it helps people keep their dignity. Because of the law, workers cannot sell their services for less than the minimum. Furthermore, employers cannot force workers to accept jobs at unfair wages. Economic theory predicts the results of economic decision, such as decisions about farm production, rent control, and the minimum wage. The predictions may be corrected only if "other things are equal". Economists do not agree on some of the predictions. They also do not agree on the value of different decisions. Some economists support a particular decision while others criticize it. Economists do agree, however, that there are no simple answers to economic questions. There is the possibility that setting maximum rent may _ .

A new Australian research indicates that children with a stutter do not suffer disadvantages at school, More than ten percent of children have a stutter by the age of four but they score just as high as other children on tests designed to judge their language, thinking skills and character. Professor Reilly's team studied over 1600 children from Melbourne, Australia. Their mothers had been filling out regular questionnaires since their babies were eight months old and the children were judged by a range of language and behaviour tests when they reached the age of four. Reilly and her colleagues asked the parents to call the study group if their children started showing signs of stuttering. Diagnoses were confirmed by a researcher, who then visited the homes of children with a stutter every month to check on their progress. By the age of four, 181 of the children studied had been diagnosed with a stutter. Follow-up visits to the 181 children who were judged after diagnoses showed just nine no longer had a stutter one year later. Stuttering children scored 5. 5 points higher than that of their non-stuttering children on language tests and 2. 6 points higher on the test of non-verbal intelligence. The researchers said it was possible that stuttering could improve language skills, or that stuttering could result from very fast language development among some children. The research suggests parents of children who stutter are usually advised to wait a year before looking for treatment --which can be expensive -- to see if the stutter goes away by itself, unless the children become very unhappy or stop talking. According to Reilly, parents should make a telephone to the study members when _ .
