Two American scientists told the people in industrial nations that they would be much healthier if they ate more of the same kind of foods eaten by humans living more than 10,000 years ago. The scientists say that the human body has changed very little since human first appeared on the earth,but the way we live has changed greatly. Our body has not been able to deal with these changes in lifestyles and this has led to new kinds of sicknesses. These new sicknesses were not known in ancient times. So they are called "diseases of civilization ".Many cancers and diseases of the blood system,including heart attacks and strokes are examples of such diseases. Scientists noted that early stoneage people used very little alcohol or tobacco ,probably none. Ancient people also got a great deal of physical exercise,but a change in food is one of the main differences between life in ancient times and life today. Stoneage people hunted wild animals for their meat ,which had much less fat than farm animals. They also ate a lot of fresh wild vegetables and fruits. They did not use milk and other dairy products ,and they made very little use of grains . But today,we eat a large amount of dairy products and grain foods. We eat six times more salt than stoneage people. We eat more sugar. We eat twice as much fat but only one third as much protein and much less vitamin C. People today probably do not want to live as people thousands of years ago did,but scientists say that we would be much healthier if we ate as those ancient people did,cutting the amount of fatty,salty and sweet foods. From this article,we know that _ are not good to our health.

It's a Friday night. Your girl friends are out at a bar and your boyfriend is playing soccer with his mates. Two text messages later, you're eating pizza and watching action movies with three guy friends. Perfect. "Guy friends" have the potential to enrich your life in ways that female friends and boyfriends just can't. For starters, they provide an insider's perspective on how men think, feel and behave. When dealing with male relatives, coworkers and even boyfriends, another man's point of view can be incredibly useful. Three hours spent analyzing a situation in a cafe with your girlfriends can't compete with a quick chat to a guy friend. Many women find that time spent with male friends can be a liberating and somewhat refreshing break from spending time with the girls. Without the judgmental gaze of other females, there is less pressure to dress up and compete for attention. Traditionally, girl-guy friendships are seen as hard to maintain. Most relationships between males and females that we come across in our day-to-day lives, whether in movies or books, are romantic by nature. These cultural images make girl-guy friendships seem impossible. Yet in reality, as gender roles loosen and equality becomes a norm in the workplace, it has become much more common for platonic friendships to blossom. "The belief that men and women can't be friends comes from another era in which women were at home and men were in the workplace, and the only way they could get together was for romance," explains psychologist Linda Sapadin to Psychology Today magazine. "Now they work together and share sports interests and socialize together." "My boyfriend has met all of my guy friends so he's quite accepting of me hanging out with them," says Nellie. "Because we've been dating so long, there's a level of trust where he knows I will make the right decision when choosing who to be friends with. "He understands that the kind of time that I spend differs between guys and girls. When I'm out with the girls, we're gossiping or talking about clothes but when I'm spending time with the guys, it's different. I think their carefree and 'whatever goes' attitude can sometimes be exactly what I need." According to what Nellie said, _

Nobel, who was born in Stockholm, is a great scientist famous for his dangerous experiments. Nobel studied in the USA and then Russia between 1850 and 1859. After his return, he started researching into bombs. As is known, bomb is dangerous to life, but Nobel was working under that condition. Once a big explosion in his lab completely destroyed the lab and caused some deaths. After that he had to experiment on a boat in a lake. He received criticism and satire , but he proceeded with the work rather than losing heart. From 1860s to 1880s, Nobel made many achievements and his inventions were first used in building roads and digging tunnels. Most of the bombs were safer and more possible to be controlled. Even at the end of the 20th century, we still used his methods. Nobel had many patents in Britain and other European countries. He was quick to see industrial openings for his scientific inventions and built up over 80 companies in 20 different countries. Indeed his greatness lay in his outstanding ability to combine the qualities of an original scientist with those of a forwardlooking industrialist. But Nobel's main concern was never with making money or even with making scientific discoveries. Seldom happy, he was always searching for a meaning to life, and from his youth, he had taken a serious interest in literature and philosophy. His greatest wish, however, was to see an end to wars, and thus peace between nations, and he spent much time and money working for this cause. To follow his will, a fund was set up to encourage people to make great progress in physics, chemistry, physiology , medicine, literature and peace. That's the Nobel Prize which means great honor to a scientist. Based on the passage, Nobel, as a scientist, _ .

Chimpanzees, long considered reluctant to share, apparently can display selfless tendencies, revealing one more key way our closest living relatives are like humans, scientists find. These findings could shed light on the evolution of _ in humans. Previously, a belief was widely held that human altruism evolved only after humans split from their ape cousins about 6 million years ago. In recent years, however, research has revealed just how much chimpanzees have in common with us. They can hunt with spears, play with dolls and mourn their partners' death. "Most of the earlier studies had presented the apes with a complex implement that helped them deliver food to themselves or others, often so complicated that the experiments tested tool skills rather than social tendencies," De Waal told Live Science. "Ours is the first study that uses no such implement at all." In addition to using complex food-delivery systems, past experiments often placed the chimpanzees so far apart that they might not have realized how their actions benefited others. In these new, simplified experiments, two apes were housed next to each other with a screen through which they could see each other. Then, one chimpanzee had to choose between two differently colored tokens from a bin, one of which represented a pro-social option, the other a selfish option. The pro-social option would cause both chimpanzees to receive a piece of banana wrapped in paper. The selfish option only rewarded the ape who made the choice. In a study with seven adult female chimps placed into various pairs, the scientists found all the apes showed a definite preference for the pro-social option. "For me, the most important finding is that like us, chimpanzees take into account the needs and wishes of others," researcher Victoria Horner, said. The chimpanzees behaved especially altruistically toward partners who either patiently waited or gently reminded them that they were there by drawing attention to themselves. They were less likely to reward partners who pressured through making a fuss, begging persistently or spitting water at them. This is opposite to a long-standing view that the chimpanzees only share food under pressure. Which of the following might be the best title of the passage?

Speaking two languages can actually help offset some effects of aging on the brain, a new study has found. Researchers tested how long it took participants to switch from one cognitive task to another, something that's known to take longer for older adults, said lead researcher, Brian Gold, a neuroscientist at the University of Kentucky. Gold's team compared task-switching speeds for younger and older adults, knowing they would find slower speeds in the older population because of previous studies. However, they found that older adults who spoke two languages were able to switch mental activities faster than those didn't . The study only looked at life-long bilinguals, defined in study as people who had spoken a second language daily since they were at least 10 years old. Gold and his team asked 30 people, either bilingual or monolingual , to have a series of tests. They found that bilingual people were not only able to switch tasks faster, they had different brain activity than their monolingual peers. Kristina called bilingualism "a beautiful natural experiment", because people grow up speaking two languages,and studies have shown that they get certain cognitive benefits from switching between languages and determining which to respond with based on what's going on around them. Gold said he grew up in Montreal, where he spoke French at school and English at home, prompting relatives to question whether his French language immersion would somehow hinder his ability to learn English. "Until very recently, learning a second language in childhood was thought of as dangerous," he said. "Actually, it's beneficial. " In Gold's opinion, learning a second language in childhood is _ .

Dyslexia is a learning disorder, it interferes with the ability to recognise words, and for some readers to understand what they have read. Experts say dyslexia affects about five to ten percent of the population of the United State. Researchers have long known that people with dyslexia write or read words and letters backwards in the wrong order. But a new study shows that people with dyslexia may have trouble redirecting their attention between senses, from seeing something to hearing something. The study suggests something that might help dyslexic people learn more quickly - play video games. Vanessa Harrar of Britain's University of Oxford led the study. She reported the findings in the journal Current Biology. The study suggests that dyslexic people may have trouble moving quickly from what they read to what they hear. Doctor Harrar calls this a " _ shifting of attention across the senses." "So, if you are trying to read something and then trying to listen to somebody who's reading aloud and you're trying to follow along with what they are reading -- they have to switch their attention from hearing what they are saying to looking at the piece of paper and back again. So we found they have quite sluggish shifting of attention across the senses," said Harrar. In the study, Doctor Harrar tested 17 people with dyslexia, and 19 others without reading problems. The volunteers were asked to push a button as quickly as possible when they heard a sound, saw a light or experienced both together. Doctor Harrar compared the speed of their reactions. She found that people with dyslexia were just as fast as the others when they saw only a picture or heard only a sound. But the dyslexics had a slower reaction time when they heard a sound and saw a picture at the same time. Doctor Harrar feels like playing action video games could help dyslexic people shift from seeing to hearing more quickly. She adds that images in video games force the eyes to move and focus quickly. "Video game types of things pop out of here and there, they move your eyes around the screen quite quickly in response to things quite quickly, and the more you play a video game the faster you get that kind of thing. So, the video game is really training the attention system to move quickly," said Harrar. The study also shows that dyslexic people have the most difficulty going between what they saw and what they heard, this may have an effect on how dyslexic children are taught how to read. When children learn the alphabet,they usually see the letter first and then hear the sound, or they see and hear the letter at the same time. The study shows that dyslexics might learn more quickly if they hear the sound of a letter or word first before seeing it. People with Dyslexia have the following problems except _ .

More than 20 million kids in the United States live with one parent. Separation and divorce are the most common reasons for this. In other cases, the mom and dad may never have lived together, or one of them may have died. Living with one parent instead of two can bring about a lot of emotions. These feelings can be pretty strong, and they can be confusing, too. You might feel terribly sad and angry because your parents divorced. Single parents are often working parents because someone needs to earn money to buy food, clothing, and a place to live in. Having a job means your mom or dad is able to provide these things and more for you. People work for other reasons, too. A job can let a person use his or her special talents and skills. A job can be important because it helps people in the community. But even though you might understand why your mom or dad has to work, sometimes it can be hard to accept. This can be especially true during the summer or school vacations. _ It can be tough when you don't have enough time with your dad or mom. When you live with one parent, that person really has to do the work of two people. Besides a job, your mom or dad is responsible for caring for the kids, the house, the yard, the car and the pets. So what can you do ? One of the best ways is to hold a family meeting. Talk about everyone's schedule for work, school, and activities. You can also talk about what jobs around the house need to be done every day. You might want to help your parent cook dinner sometimes. That can be both fun and helpful to your parent. Maybe you can also schedule a weekly game or a movie at night. Which of the following statements is NOT true according to the passage?

With only two weeks to go before Christmas, buying presents is a lug priority for a lot of people. However, this year not so many people are leaving their homes to browse around the shops. These days lots of people do their shopping in the comfort of their own home with the help of the Internet. Online shopping is becoming more and more popular for a number of reasons: prices are often lower online, you don't have to queue up in busy shops and you can buy almost any product imagin- able with just a few clicks of your mouse. Computer trends are often man-dominated but this year women are expected to do more shop-ping on the Internet than men. It seems .that women are now more attracted to the convenience of on-line shopping than they used to be. Average spending online this Christmas by women will rise to $240 compared to the slightly lower average $233 for men, while the average spending per person on the high street is only $197. 70% of lnternet users, male and female, are now buying their Christmas gifts online. In the past a lot of people were unwilling to shop online. Many were worried about the security of entering their card details on the Intemet and the reliability of the Internet but as shopping; online has become more widespread, these worries have begun to disappear. 45% of Internet users still do have security worries but it hasn't slowed the ever-increasing numbers of online shoppers. One victim of the online shopping boom is the UK high street. Christmas trading can represent up to 60% of turnover for some stores. Many companies are concerned that not enough shoppers are coming through their doors in the run-up to Christmas. As a result there are lots of special offers in the shops. Most shops traditionally have sales after Christmas but this year the bargains have come early. Why were people unwilling to shop online in the past?

"Because men were against shopping online.",
"Because there were fewer goods on the Internet.",

It's impolite to spit out the first bite of your dinner. But to a type of Australian snake, this rude behavior is a matter of life and death. The snake, called a floodplain death adder , eats two types of frogs that are hard to stomach. The frogs produce chemicals to defend them from predators . One of these species, the Dahl's frog, can kill a snake that tries to eat it. The other species, the marbled frog, is less dangerous but still tough to eat. When attacked, _ produces a glue like substance. Leaves and branches get caught up in this material, making a big sticky mess that gets in the way of anything trying to swallow it. A marbled frog can even get stuck on the head of an attacking snake. Both frogs have good defense methods. But the floodplain death adder knows how to get around each of them. Floodplain death adders quickly strike these frogs, using their poisonous teeth to inject poison. But then, instead of swallowing their dinner immediately, the snakes sit back and wait for their preys to become safe to eat. That's because both the Dahl's frog's protective toxin and the marbled frog's glue break down over time. After a while, the frog toxin is no longer poisonous and the glue is no longer sticky. The two substances break down at different rates, and floodplain death adders seem to know the difference, And adder waits for a different length of time depending on the species of frog it just struck. The stickiness of the marbled frog glue decreased by as much as two-thirds after just 10 minutes. And that's just about how long an adder waits before eating a marbled frog. On the other hand, the snakes wait for about 40 minutes before eating a Dahl's frog. That's enough time for the frog's toxin to break down into harmless substances. But even a quick strike gives a taste of the Dahl frog's toxin. After striking such a frog, a floodplain death adder thrashes around and lies on its back with its mouth open, It's like the snake has just had a mouthful of chili pepper. By comparison, when given frogs that have no chemical defenses, floodplain death adders eat their prey immediately after striking. Snakes, despite the fact that they've got this tiny pea-size brain are clearly capable of recognizing what kind of frog they've bitten. The glue produced by the marbled frog is used for_.

To become a doctor in the United States, students usually attend four years of medical school after they complete college. Then these young doctors work in hospitals for several years to complete a training program called a residency . These medical residents provide hospitals with needed services in return for not much pay. They work under the supervision of medical professors and more experienced doctors. Medical residents treat patients . they carry out tests. They perform operations. They complete records. In hospitals with few nurses, residents also do work formerly done by nurses. Some medical residents work one-hundred or more hours in a single week. _ Critics of this system say medical residents work too long and do not get enough res. They say these young doctors may be too tired to perform their medical duties effectively. Now, the government will limit the number of hours of work that residents can work. Most doctors in training will be limited to eighty-four hours of work each week. They will have work periods of no more than twenty-four hours at one time. They will have ten hours of rest between work periods. Medical residents will have one day each week when they do not have to work. Any work they accept outside their hospitals will be limited.Experienced doctors and medical professors will closely supervise the residents to make sure they are not too tired to work. Many medical residents welcomed the work limits. Others, however, said the new policy may interfere with patient care and their own medical education. Why does the government limit the number of hours that residents work?

Body language is a very powerful tool of communication, not only between people but in the animal world as well. In many instances, we produce idioms (,)which are all understandable by borrowing examples from animal communication. For example, we know that a frightened cat will arch its back high in rigid curve . From this starting-point we might hear the expression, "He gets my back up!" meaning "He makes me angry." In the same manner, we know that many animals, if challenged by attackers, will not turn and run away because this will encourage the attacker to attack them more forcefully. Instead, they will move backwards slowly to get out of harm's way, always still facing their attacker.We call this action " _ " and it can be used just as well with humans as with animals. In the case of humans, however, the back-off may not be physical but oral, as in using a kinder tone of voice and gentler words instead of fighting against the attackers. Which of the following is NOT true according to the text?

She might not be paid, but Carnegie Mellon University's newest staff member does all that a typical receptionist can do: give directions, answer the phone -- and even gossip about her life. University officials revealed what it considers to be the world's first robot receptionist with a personality of her own. The blond receptionist, named "Valerie," puts on a headset and interacts with people by talking about her boss, her psychiatrist and her dream. Valerie, the roboceptionist, sits in a custom-made booth at the entrance of a computer science hall. With her ability to distinguish motion, she greets visitors as they come near. Type in a question on a keyboard and she gives directions around the Pittsburgh campus and provides visitors information about the weather. More than that, she tells stories about her life. From her booth, passers-by often can hear her talking on the phone. She recognizes when someone is in front of her and remembers their characteristics. She can change between tasks from talking on the phone to answering a question. Valerie, however, does have her limit. She is a drum-shaped mechanical device with a digitally lively face that appears on a computer display. Visitors have to type on a keyboard to communicate with her. And she understands only simple questions. Eventually her creators would like to install face recognition so people don't have to insert an identity card for her to remember them. And people won't have to type their questions on a keyboard if they can solve the problem of voice recognition in a crowded hall. Valerie will tell the story of a robot living in a human world.

Now satellites are helping to forecast the weather. They are in space and they can reach any part of the world. The satellites take pictures of the atmosphere , because this is where the weather forms . They send these pictures to the weather station. So meteorologists can see the weather of any part of the world. From the pictures, the scientists can often say how the weather will change. Today, nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive new pictures, the meteorologists compare them with earlier ones. Perhaps they may find that the clouds have changed during the last few hours .This may mean the weather on the ground may soon change, too. In their next weather forecast, the meteorologists can say this. So the weather satellites are a great help to the meteorologists. Before satellites were invented, the scientists could forecast the weather for about 24 or 48 hours. Now they can make good forecasts for 3 or 5 days. Soon, perhaps , they may forecast the weather for a week or more ahead Satellites travel _ .

Bamboo is one of nature's most surprising plants.Many people call this plant a tree,but it is a kind of grass. Like other kinds of grass,a bamboo plant may be cut very low to the ground,but it will grow back very quickly.A Japanese scientist reported one bamboo plant which grew 1.5 meters in 24 hours ! Bamboo grows almost everywhere in the world except Europe.There are more than 1,000 kinds of bamboo. Not all bamboo looks the same.Some bamboo plants are very thin.They may only grow to be a few centimeters wide while others may grow to more than 3 0 centimeters across.This plant also comes in different colors,from yellow to black to green. Bamboo has been used to make things such as hats and kitchen tools.Because it is strong, bamboo is also used to build buildings. Many Asian countries have used bamboo for hundreds of years.They often use bamboo for buildings and supporting new buildings and bridges while they are being built. In Africa ,poor farmers are taught how to find water using bamboo.These African countries need cheap way to find water because they have no money ,and their fields often die from no rain and no water.Bamboo pipes help poor farmers bring water to their fields without spending a lot of money. How is bamboo like grass?

Have you ever felt that you want more friends? Have you found that you don't know how to make friends? Don't worry. It's easier than it looks. Start with small actions. If you're uncomfortable with long conversations with people, start by just saying "hi" and asking what the person is doing. Even if you do more listening than talking in the beginning, people will usually still like you. When it comes to conversations, remember "F.O.R.". It stands for family, occupation and recreation . You are most likely to be asked about these three topics when you meet someone new. Most people feel comfortable talking about the three topics. The great thing is that you also can communicate with someone new in these three areas. Honesty is the best policy. In friendship, "honesty" is the fundamental quality that one must have. One should always be honest with his or her friends. Don't laugh at people's fault. Praise them honestly and openly. Say you are sorry if you hurt your friend. Give more than you take. Be there when they need you, encourage them; we all need encouragement now and then. Encourage their dreams. Life seems meaningless without them. Wish your friends good luck. Examine your purpose before you "help out". Love and never forget them. Which would be the best title for this passage?

Food is very important.Everyone needs to eat well if he wants to have a strong body.Our minds also need a kind of food.This kind of food is knowledge . When we are very young,we start getting knowledge.Kids like watching and listening.Color pictures especially interest them.When kids are older,they enjoy reading.When something interests them,they love to ask questions. Our minds,like our bodies,always need the best food.Studying on our own brings the most knowledge. If someone is always telling us answers,we never learn well.When we study correctly and get knowledge on our own,we learn more and understand better. Everyone needs to eat well because it can help people _ .

Every country has its own way of cooking. American people have their way of cooking, don't they? Most people in the United States like fast food, but if you think that American people don't like cooking, you are wrong. It's true that most Americans eat fast food for their breakfast and lunch, but they also think cooking is interesting. Parents see the importance of teaching their children how to cook, and most Americans say that home cooked meals are the best. Americans have their own way of cooking. For example, baking is the most popular way of cooking in America. Most American families have ovens. American cooks pay attention to the balance of food. In planning a big meal, they try to cook meat, a few vegetables, some bread and often some sweet food. They also like to make the meal look beautiful. There are many kinds of food of different colors, so the meal is healthy and looks beautiful, too. Which is right according to the passage?

Since the 1970s, scientists have been searching for ways to link the brain with computers.Brain-computer interface(BCI) technology could help people with disabilities send commands to machines. Recently, two researchers, Jose Millan and Michele Tavella from the Federal Polytechnic School in Lausanne, Switzerland, demonstrated a small robotic wheelchair directed by a person's thoughts. In the laboratory, Tavella operated the wheelchair just by thinking about moving his left or right hand.He could even talk as he watched the vehicle and guided it with his thoughts. "Our brain has billions of nerve cells.These send signals through the spinal cord to the muscles to give us the ability to move.But spinal cord injuries or other conditions can prevent these weak electrical signals from reaching the muscles," Tavella says."Our system allows disabled people to communicate with external world and also to control devices." The researchers designed a special cap for the user.This head cover picks up the signals from the scalp and sends them to a computer.The computer interprets the signals and commands the motorized wheelchair. The wheelchair also has two cameras that identify objects in its path.They help the computer react to commands from the brain. Prof.Millan, the team leader, says scientists keep improving the computer software that interprets brain signals and turns them into simple commands."The practical possibilities that BCI technology offers to disabled people can be grouped in two categories: communication, and controlling devices.One example is this wheelchair." He says his team has set two goals.One is testing with real patients, so as to prove that this is a technology they can benefit from.And the other is to guarantee that they can use the technology over long periods of time. BCI is a technology that can _

A recent survey made by BUPA, an international healthcare provider, shows that 54 percent of Chinese people aged between 45 and 54 consider themselves old, while 28 percent say that the thought of getting old upsets them. 25 percent are afraid of getting old, and a third worry about life in old age. BUPA made the survey among 12,262 people from 12 countries over 2 months, starting in June 2010. The survey shows that 72 percent of international participants aged over 65 don't feel old and that 67 percent still feel healthy. On the other hand, 65 percent of Chinese feel old even before reaching 60. About one third of those surveyed in China said they have enough savings , and 46 percent are insured . Around 60 percent of the Chinese participants hope they will be taken care of by family members. According to the survey, the French hold the most positive attitude towards getting old, with 32 percent of them considering age 80 and up old. 17 percent of Brazilians look forward to old age, compared with 3 percent globally. Indians are not bothered by old age, as 70 percent said that they don't feel that they will be affected by old age and 71 percent say they have already made preparations for this stage of life. The illnesses that most people around the world are worried about are cancer and Alzheimer's disease. According to the survey, many Chinese people surveyed feel old before they are _ .

An aspirin a day keeps the doctor away. Aspirin has long been praised as a wonder drug and has been in your family since you can remember. Not only does it cure pain, it also lowers the risk of heart attack and stroke . But taking the pills daily may not work for everyone. Although taking an occasional aspirin or two is safe for most adults to use for headaches,body aches or fever, daily use of aspirin can have serious side effects. Up to 60 per cent of us,both healthy people and those being treated for all types of heart disease, may have some level of resistance to aspirin' s benefits. Aspirin keeps platelets from sticking, lowering the risk of clotting . People who are aspirin - resistant still get pain relief but not the full blood - thinning effects. How do you know whether you' re resistant? New blood tests can help your doctor decide whether to give you a different medicine, especially if you' re at risk or are being treated for heart disease. The tests aren' t yet widely available, but it doesn' t hurt to ask. People taking aspirin daily should limit the amount of alcohol they drink because of its additional blood - thinning effects and potential to upset your stomach. Thus you should not have more than one drink if you' re a woman or two dr/nks a day if you' re a man. Does daily aspirin treatment differ between men and women? Recent studies have focused on the effects of aspirin in women, finding that its effects differ between the sexes, and for women, between age groups. All in all, aspirin is still an effective, affordable and simple option for many people at risk of heart attack and stroke. Though it is readily available, always check with your doctor before starting daily aspirin treatment. We can/cam from the passage that _

Children who are raised in households with dogs during their first year of life may have a lower risk of asthma a few years later, a new study suggests. In the study, the researchers looked at early exposure to dogs and farm animals and the rate of asthma among about 276,000 school-age children in Sweden. Among the school-age kids in the study, those who had been exposed to dogs during their first year of life were 13 percent less likely to have asthma at age 6. The researchers said they don't know for sure what exactly may explain the relationship between early exposure to animals and a reduced risk of asthma."It might be due to a single factor, or more likely, a combination of several factors related to a dog ownership lifestyle or dog owners' attitudes, such as kids' exposure to household dirt and pet dust, time spent outdoors or being physically active,"Fall told LiveScience."As a parent in a dog-and-baby household, it is nearly impossible to keep everything clean, and maybe this is a good thing for your baby's future health." Currently, one of the main hypotheses that aim to explain the link between a lower risk of asthma and early exposure to pets is that"kids in animal environments breathe air that contains more bacteria and bacterial fragments, which actually could lower their risk of asthma,"she said. Previous research on having pets and the risk of asthma in kids has mixed results. For example, the results of a 2001 review of previous studies suggested that exposure to pets was linked to an increased risk of asthma in children. But a 2012 review suggested that exposure to pets, especially dogs, was tied to a decreased risk of asthma and allergies in childhood. "My take-home message from this study is that parents at this point do not need to worry about keeping their dog when expecting a baby for fear of asthmatic disease,"Fall said."I do want to be clear that this recommendation is valid only for families without a child already having allergies. If they already have a furred-animal-allergic child, we do not recommend them to get a furred pet." According to this hypothesis, being exposed to bacteria early in life is crucial for shaping a healthy immune system, and may play a role in modifying a person's risk of developing asthma and allergies."As to allergies and asthma, it is partially genetic, but studies like this do show us that your environment does play a key role in the development of your immune system, and the development of allergies and asthma,"Parikh told LiveScience. According to the passage, the school-age kids exposed to pets .

Depression is a serious problem today.Depression causes workers to be unproductive,causing companies and countries to lose billions of dollars.One expert says that depression is like cancer because it is "widespread,costly and deadly".Depression hits one person in five around the world. Although people have believed depression to be a problem among the rich and educated,studies show that depression is a problem among everyone. Over any six-month period,between five to seven percent of the world's population will be suffering from a serious depression. suicide rates among people suffering from the disease in its extreme,or clinical form were 80 percent higher than in the population at large,and sufferers were four times more likely to have heart attacks. People who suffer from depression often have problems sleeping,getting up on time,and doing work productively. Depression,which researchers agree has its origin in the genes ,brings loss of confidence and ability to concentrate-making it impossible for employees and managers to work efficiently. Depression is made more serious in China by Chinese's inability to face it.Many people believe that depressed people are either weak or lazy. Besides,there is no good treatment,with few specialists available. "Most patients in China just don't get help,"a Chinese doctor says."In my hospital.I have to see 30 or 40 patients in a morning,just have time to say "Hello how do you feel?" In Western countries,people are not afraid to admit that they have depression,but most do not tell it to their boss,because they fear that their boss would fire them. "In my experience,aging bosses are the most willing to admit they have it. Because they feel the most secure about themselves,"an American doctor says. Hopefully,in the near future,people around the world will be able to admit that they have depression so that they can get the right treatment. Compared to normal people,the depressed people are likely to be###.

Huzhou, May 10 (Huzhou Daily)--A city eye examination has showed that Huzhou primary and high school children's eyesight has been getting worse. It showed test results were lower than those from the last examination in 2010. Only 10% of the tested students had good eyesight, but more than 30 percent in 2010. The examination covered 1,770 students from 54 classes. They were from primary and high schools in 5 districts. According to the test results of the junior high school group, children from Anji District scored an average of four, much lower than 4.8. Below four is classed as short-sightedness. None of the students from Deqing District tested above 4.8. Huzhou would adopt measures to improve children's eyesight. Most importantly, students should be freed from the burden of exams and relax their eyes more often every day. Which of the following is classed as short-sightedness according to the passage?

Internet use appears to cause a drop in psychological health, according to a research at Carnegie Mellon University. Even people who spent just a few hours a week on the Internet experienced more depression and loneliness than those who used Internet less frequently, the two-year study showed. And it wasn't that people who were already feeling bad spent more time on the Internet, but that using the Net actually appeared to cause the bad feeling. Researchers are puzzled by the results, which were completely the opposite to their experiences. They expected that the Net would prove socially healthier than television, since the Net allows users to choose the information and to communicate with others. The fact that Internet use reduces time available for family and friends may explain the drop-in well-being, researchers supposed. Faceless, bodiless "virtual" communication may be less psychologically satisfying than actual conversation, and the relationships formed through it may be shallower. Another possibility is that knowing the wider world via the Net makes users less satisfied with their lives. "But it's important to remember this is not about the technology; it's about how it is used," says psychologist Christine Riley of Intel, one of the study founders. "It really points to the need for considering social factors in terms of how you design applications and services for technology." The best title of the passage probably is _ .

A Battery's Nightmare Portable electronics that can be carried about easily are only as good as their batteries and, let's face it, batteries aren't very good, especially when compared with, say, petrol, which packs 100 times a battery's energy into an equal space. That's why a large group of mechanical engineers (centered at the Massachusetts Institute of Technology, but with partners at other universities and companies) are hard at work in an effort to replace batteries with a tiny engine that runs on fuel. Imagine a battery-free life! When the fuel runs out in your mobile phone, you just fill up and go. The engine---about the size of a ten-cent coin---starts with a combustion chamber that burns hydrogen. Its tiny parts are etched onto silicon wafers in the same manner that computer parts are etched onto integrated circuits . The first engine is made up of five wafers. And since these wafers could be produced in much the same way as computer chips, they could probably be produced quite cheaply. But the _ in all this nice detail is efficiency. Tiny engine parts don't always behave like the bigger parts of the first engine. Something between the parts can slow down the works, according to Columbia University Professor LucFrechette, one of the engine's designers. Extreme heat from the combustion chamber is also a problem, often leaking to other parts of the engine. The scientists' goal is to create an engine that will operate 10 times better than batteries operate. Frechette says that a complete system, with all parts in place and working, will be set up in the next couple of years, but commercial models aren't likely until at least the end of the next ten years. According to the passage, the title suggests that _ .

Work Your Mind Here's something to think about the next time you ask your teacher for help: struggling with schoolwork on your own can help you learn. According to a recent study, the more you struggle while you are learning new information, the better you can remember it later. This theory might surprise you. When teachers are presenting new information, they often give students lots of help. But a new study shows this may not be the best way to support learning. "Don't be too quick to get help when learning something new," education expert Manu Kapur told TFK. "Try to work on it yourself even if it means trying different ways." Kapur came up with the idea that struggling can lead to better learning. Then he tested it out on students in Singapore. He separated students into two groups. In the first group, students were asked to solve math problems with the teacher's help. In the second group, students were asked to solve the same problems by helping one another, instead of getting help from the teacher. With the teacher's help, students in the first group were able to find the correct answers. Students in the second group did not solve the problems correctly. But they did come up with a lot of good ideas. The students were then tested on what they had learned. The group without any help from a teacher scored much higher than the group who had help. Kapur said working to find the answers helped students understand the process, not just the solution. Kapur's advice for kids is to put a lot of effort into learning something new rather than going to your teacher for help. "Simply doing a little work or nothing at all won't work," says Kapur. "The struggle needs to be a genuine attempt to figure out or solve a problem in as many ways as possible." How did Kapur check his idea on better learning?

If you've ever washed your hair just before going to the salon to get another better look, you will be told by the stylist, freshly washed and dried hair isn't as easy to work with as hair that was washed a day or two ago. Your color will last longer. If you color your hair, washing daily can _ your color and lead to more trips to the salon. Keep your hair looking bright by only washing every other day. When you wash your hair, do so with a shampoo so that you can make sure the color doesn't lose. It will be healthier. The more you wash your hair, the more you're removing your hair's natural oil. That's right - too much time with the shampoo can really mean your hair become less soft and shining. Over-washing can dry hair out, which isn't a good idea. Keep your hair healthy by avoiding washing your hair every day. Washing and drying take a lot of time for those of us with long hair.

Not all think laughter is the best medicine, but it seems to help.So scientists carried on a new study of diabetes patients who were given a good dose of humor for a year to prove it. Researchers divide 20 high-risk diabetic patients into two groups.Both groups were given standard diabetes medicine.Group L viewed 30 minutes of humor of their choice, while Group C, the control group, did not.This went on for a year of treatments. By two months into the study, the patients in the laughter group had lower level of the hormones epinephrine , considered to cause stress, which is known to be deadly.After the 12 months, _ rises 26 percent in Group L but only 3 percent in Group C.In another measure, C-reactive proteins, a maker of heart disease, drop 66 percent in the laughter group but only 26 percent in the control group. "The best doctors believe that there is a physical good brought about by the positive emotion, happy laughter," said study leader Lee Berk of Loma Linda University.And other research has found that humor makes us more hopeful.Still, more study is needed, Berk said.The research by Berk found that humor can bring about similar changes in body chemistry, which was proved in the new study.The research result will be presented this month at the meeting in the US.Research at the University of Maryland School of Medicine shows that laughter causes the inner lining of blood vessels to expand, increasing blood flow in a way thought to be healthy. "Lifestyle choices have an important effect on health and these are choices which we and patients should pay attention to, rather than prevention and treatment," Berk said in a statement this week. Why did the scientists carry on the new research?

Karl Fleming joined the military because he needed a change in his life. He had a successful career with a shipping company but he wanted to do something more. He found that something in the U.S. army. Fleming began his service in 2009 and never looked back. A few years later, Fleming volunteered to go to Afghanistan. There, he worked as a bodyguard for the U.S. Army Corps of Engineers. He enjoyed it, except for the almost-nightly rocket attacks. Karl was never hit directly by a rocket, but he didn't need to be to feel its effects. The rockets caused severe shaking, shaking so bad that Fleming was left with many injuries. He was also diagnosed with concussions and Post-Traumatic Stress Disorder(PTSD). Fleming said he was down but not out. Once he returned from Afghanistan, Fleming underwent one test after another. At first, Fleming said he thought he could recover or be able to return to duty and realize his dream of becoming an officer. But then came the news he had never imagined: Fleming would never be an officer because he was too injured to continue. Fleming said he was depressed after learning his military career was over. Add that to the memory loss, extreme anxiety and the many painful medical procedures he was already experiencing. He rarely ventured outside on the weekend. Instead, he preferred to sleep in. All that changed, however, with Fleming's service dog, Kuchar. Fleming said he had heard dogs could help people suffering from PTSD, so he started doing research. Karl eventually selected K9s for Warriors, which is where he met Kuchar, a yellow lab. Fleming and Kuchar trained together for weeks, before returning to Fort Benning. K9s for Warriors provided Fleming with Kuchar and the training for free. Life with Kuchar has been life-changing. Fleming doesn't sleep in any more because Kuchar won't let him. Instead, they venture out into a world Karl was once afraid of -- a world for Fleming that now seems impossible to imagine without Kuchar by his side. The passage is mainly about Fleming's _ .

Below is a selection from a popular science book. If blood is red, why are veins blue? Actually, veins are not blue at all. They are more of a clear, yellowish colour. Although blood looks red when it's outside the body, when it's sitting in a vein near the surface of the skin, it's more of a dark reddish purple colour. At the right depth, these blood-filled veins reflect less red light than the surrounding skin, making them look blue by comparison. Which works harder, your heart or your brain? This question depends on whether you're busy thinking or busy exercising. Your heart works up to three times harder during exercise, and shifts enough blood over a lifetime to fill a supertanker. But, in the long run, your brain probably tips it, because even when you're sitting still your brain is using twice as much energy as your heart, and it takes four to five times as much blood to feed it. Do old people shrink as they age? Yes and no. Many people do get shorter as they age. But, when they do, it isn't because they're shrinking all over. They simply lose height as their spine becomes shorter and more curved due to disuse and the effects of gravity . Many (but not all) men and women do lose height as they get older. Men lose an average of 3-4 cm in height as they age, while women may lose 5 cm or more. If you live to be 200 years old, would you keep shrinking till you were, like 60 cm tall, like a little boy again?No, because old people don't really shrink!It is not that they are growing backwards--their legs, arms and backbones getting shorter. When they do get shorter, it's because the spine has shortened a little. Or, more often, become more bent and curved. Why does spinning make you dizzy ? Because your brain gets confused between what you're seeing and what you're feeling. The brain senses that you're spinning using special gravity and motion sensing organs in your inner ear, which work together with your eyes to keep your vision and balance stable. But when you suddenly stop spinning , the system goes out of control, and your brain thinks you're moving while you're not! Where do feelings and emotions come from? Mostly from an ancient part of the brain called the limbic system. All mammals have this brain area--from mice to dogs, cats, and humans. So all mammals feel basic emotions like fear, pain and pleasure. But since human feelings also involve other newer bits of the brain, we feel more complex emotions than any other animal on the planet. What is the main purpose of the selection?

While Jennifer was at home taking an online exam for her business law class, a monitor a few hundred miles away was watching her every move. Using a web camera equipped in Jennifer's Los Angeles apartment, the monitor in Phoenix tracked how frequently her eyes moved from the computer screen and listened for the secret sounds of a possible helper in the room. Her Internet access was locked - remotely - to prevent Internet searches , and her typing style was analyzed to make sure she was who she said she was: Did she enter her student number at the same speed as she had in the past? Or was she slowing down? In the battle against cheating, this is the _ and a key to encourage honesty in the booming field of online education. The technology gives trust to the entire system, to the institution and to online education in general. Only with solid measures against cheating, experts say, can Internet universities show that their exams and diplomas are valid - that students haven't just searched the Internet to get the right answers. Although online classes have existed for more than a decade, the concern over cheating has become sharper in the last year with the growth of "open online courses." Private colleges, public universities and corporations are jumping into the online education field, spending millions of dollars to attract potential students, while also taking steps to help guarantee honesty at a distance. Aside from the web cameras, a number of other high-tech methods are becoming increasingly popular. Among them are programs that check students' identities using personal information, such as the telephone number they once used. Other programs can produce unique exam by drawing on a large list of questions and can recognize possible cheaters by analyzing whether difficult test question are answered at the same speed as easy ones. As in many university classes, term papers are scanned against some large Internet data banks for cheating. Why was Jennifer watched in an online exam?

Online clothes shoppers will be told exactly what size is best. for them using new software which combines with their web camera or smart phone to form a"3D tape measure". Scientists from Surrey University and design experts from the London College of Fashion are developing a program which can take precise waist, hip, chest and other measurements from camera images. Using the person's height as a starting point,the software will be able to build up a 3D image and estimate their size at various different points on the body, based on their overall proportions. The result will be a more accurate sizing guide than previous systems based on waist size or a "small/medium/large"scale, which rely on limited measurements and the buyer's perception of their own body size. Shoppers and retailers who choose to sign up for the project could save millions of pounds a year in postage costs by removing the need to order multiple sizes of the same garment and send back ill-fitting clothes, researchers claimed. The project, sponsored by the Engineering and Physical Sciences Research Council(EPSRC), is expected to be brought to market within two years. After choosing an item, the shopper will activate the software, enter their height, stand in front of their webcam or smart phone in their underwear and take a photograph. The software will not store or transmit the image to the internet, but will use it to judge the person's dimensions at various points on their body. Philip Delamore of the London College of Fashion said:"The potential benefits for the fashion industry and for shoppers are huge. Currently, it's common for online shoppers to order two or three different sizes of the same item of clothing at the same time, as they're unsure which one will fit best." Compared with the traditional sizing system, a 3D tape measure is _ .

I was born in Tuckahoe,Talbot Country,Maryland. I have no accurate knowledge of my age,never having seen any record containing it. By far the larger part of the slaves know as little of their ages as horses know of theirs,and it is the wish of most masters within my knowledge to keep their slaves thus ignorant .I do not remember having ever met a slave who could tell of his birthday. They seldom come nearer to _ than plantingtime,harvesting,springtime,or falltime. A lack of information concerning my own was a source of unhappiness to me even during childhood. The white children could tell their ages,but I could not tell. Why the same right ought to be taken away from me!I was not allowed to ask my master about it. He considered all such questions on the part of a slave improper and impolite. The nearest estimate I can live makes me now between twentyseven and twentyeight years of age. I come to this,from hearing my master say,some time during 1835,I was about seventeen years old. My mother was named Harriet Bailey. She was the daughter of Isaac and Betsey Bailey,both colored,and quite dark. My father was a white man. The opinion was also whispered that my master was my father;but of the correctness of this opinion,I know nothing and I have no means to know. My mother and I were separated when I was but an infant--before I knew her as my mother. It is a common custom,in the part of Maryland from which I ran away,to part children from their mothers at a very early age. Frequently,before the child has reached its twelfth month,its mother is taken from it,and hired out on some farm a considerable distance off,and the child is placed under the care of an older woman,too old for field labor. How does the writer feel about not knowing his age?

Working the night shift a few nights a month can do more than leave your eyes bleary-eyed ,suggests a study on Wednesday. It just might increase your risk of color1ectal cancer .Nurses who worked the night shift at least three times a month for t5 years or more were 35%more likely to develop that type of cancer than nurses who never worked nights,Harvard University researchers report in the Journal of the National Cancer Institute. The finding,from the ongoing Nurses Health Study,is the first to link night shift work with a higher risk of color1ectal cancer,expected to kill 57,100 Americans this, according to the American Cancer Society.Another research,including a report out of the Nurses Health Study, has suggested that working night shifts increases women's breast cancer risk. The researchers asked 78,586 nurses whether they had ever worked three or more night shifts a month.The nurses indicated whether they had done so for less than 15 years or 15 years or more.The scientists followed the women to see who developed color1ectal cancer. Researchers believe that lowered levels of melatonin might increase night-shift workers' cancer risk.Melatonin levels usually reach the highest point in the middle of the night. Turn on the lights,though,and _ dropped measurably in just 10 minutes,says Richard Stevens a cancer epidemiologist at the University of Connecticut who did not take part in the new study.After two weeks of continuous nightly exposure to light,humans experience a sharp drop in melatonin production,Nurses Health Study researchers write. In the lab,melatonin appears to stop tumor growth.Other studies suggest that color1ectal cancer patients have lower blood levels of melatonin than healthy people,the authors write.However,that could be a result of the disease,not a cause of it.Stevens says. According to Nurses Health Study,which of the following statements is NOT true?

The flying fox is not a fox at all. It is an extra large bat that has got a fox's head, and that feeds on fruit. Like all bats, flying foxes hang themselves by their toes when at rest, and travel in great crowds when out flying. A group will live in one place for years. Sometimes several hundreds of them occupy a single tree. As they return to the tree towards sunrise, they quarrel among themselves and fight for the best places until long after daylight. Flying foxes have babies once a year, giving birth to only one at a time. At first the mother has to carry the baby on her chest wherever she goes. Later she leaves it hanging up, and brings back food for it to eat. Sometimes a baby bat falls to the ground. Then the older ones fly down and try to pick it up. If they fail to do so, it will die. Often hundreds of baby bats can be found lying on the ground at the foot of the tree. How do flying foxes care for their young?

You know eating fruit and vegetables is virtuous. But did you know it can also make you look good? People who increased their intake over just six weeks developed a healthy glow and appeared more attractive, researchers found. Scientists at St Andrews University found eating them subtly increased yellow and red pigments in the volunteers' skin. They monitored the food intake of 35 people and took pictures of their faces, arms and hands using a sensitive camera at the start, and after three and six weeks. Increasing their intake of greens by 2.9 portions a day was found to make the person look healthier and an extra 3.3 portion could enhance their attractiveness, when their photographs were rated by others. Fruit and vegetables are rich in carotenoids , which are known to protect against cell damage from pollution and UV rays, and can also prevent age-related diseases including heart disease and cancer. But while it was known eating extreme amounts of certain vegetables such as carrots could turn skin orange, it was not known a small increase was perceptible to others and was seen as _ . A camera measured changes to the skin's redness, yellowness and lightness, and found it significantly changed in people who naturally increased their intake. These changes were not evident at three weeks. Using light sensors, the researchers showed these red and yellow hues(,) were linked with the levels of carotenoids in their skin. There are hundreds of carotenoids but those thought to have the most dramatic effect are lycopene which gives tomatoes and red peppers their red color1 - and beta-carotene found in carrots as well as broccoli, squash, and spinach. Skin color1 is also affected by chemicals called polyphenols , found in apples, blueberries and cherries, which cause blood rush to the skin surface. Among hundreds of carotenoids, which are most effective? _

In March 2004, Joe Ryan got a collection notice from a billing agency for Littleton Adventist Hospital near prefix = st1 /Denver,Colorado. The hospital wanted payment for surgery totaling $41,188. Ryan had never set foot in that hospital. Obviously there was some mistake. "I thought it was a joke," says Ryan. But when he called the billing agency, nobody laughed. Someone named Joe Ryan, using Ryan's Social Security number, had indeed been admitted for surgery. He figured clearing this up would take just a few phone calls. Two years later, Ryan continues to suffer from the damage to his credit rating and still doesn't know if his medical record has been cleared of wrong information. Joe Ryan was the victim of a little-known but frightening type of consumer fraud that is on the rise: medical identity theft, which involves using your name to get drugs, expensive medical treatment and even cheating insurance payments. As Ryan discovered, money isn't the half of it. When someone steals your name to receive health care, his medical history becomes part of your record -- and setting the record straight can be extremely difficult. That's because, in part, the information is distributed among dozens of caregivers, from doctors to medicine stores to insurance companies and labs. "I wanted to help straighten this out," says Ryan, "so I went to the hospital, and they had a three-inch-thick record for me, but they wouldn't let me see it. I showed them my ID, and they said that's not Joe Ryan's signature. Well, of course not! They had this other guy's signature." Ryan had fallen into a victim's Catch-22: If your record doesn't appear to be yours, you may not have the right to see it, much less change it. Ryan's next step was a visit to the Police Department. But the cops concluded there was not much they could do; local law enforcement has little experience with medical ID theft, and cases can end up being considered a civil matter. An even worse consequence of medical ID theft is _ .

Has anyone noticed how, with the passage of time, one's relationship with one's grown-up daughters and sons becomes changed? I've been aware of this for some time but I'm not quite sure how to deal with it. Take the kitchen sink for example. Following a family get-together at my place, I walked into the kitchen to find Kate, my daughter carefully cleaning the sink. "Don't do that; what are you doing that for?" I said, unhappy about the hidden criticism. "Mum," she said, "you really ought to put your glasses on when you clean the sink. Behind the tap here was black!" But it's not just things like kitchen sinks. Another time Kate arrived to pick me up to lunch. She looked at me and then asked, "Mum, why do you use brown eyebrow pencil when your hair is grey?" A sudden memory of her, aged 14, going to her first mixed party flooded back. She had come in to say goodbye. For a moment I thought she'd been an accident. Both eyes were black. I remember suggesting that perhaps a little less eye make-up might be more effective. Now I told her, "My hair used to be brown." "It looks absurd." "Mrs. Menzies had dark eyebrows with grey hair." "Yes, but you're not Mrs. Menzies, are you?" she said triumphantly, as if that proved her point. But a recent event made me realize that something really must be done. She had returned some for a few weeks before getting married. One evening I went out on a dinner date. By the time my companion left me at the front door, it was about 2am. As I stepped in, an angry figure in a white nightgown stopped me. "Well, what time of night is this to be coming home?" she shouted. "Where have you been? I've been worried sick!" Shades of the past come back to disturb me. But what should I do about all this? Nothing, probably. Maybe, after all, it's only a stage young people are going through. The author writes the stories to prove that_.

Many animals hide to stay alive. They hide in many ways. Some animals hide in leaves; some animals hide in snow. Usually their colors or shapes help protect them. It's hard to see an Arctic bear in snow. Its white fur helps protect it. Chameleons can hide by changing colors. Their skin turns the same color as what is around them. Some chameleons can change colors in five minutes. Many animals try to look bigger than they are to stay alive. Some animals can make other animals think they are very big. If they look very big, animals that are looking for food will run away. Bears can walk on two legs. They look very, very scary. Some animals will run away from them. Many animals try to stay around other animals. This helps them stay alive. Zebras stay close together so that they can help each other look out of danger. Seeing many stripes at once can also confuse animals that want to eat them. Some birds stay in a circle, each toward a different direction. In this way they can also help each other stay alive by looking around for animals that many want to eat one of them. Why do animals try to look bigger than they are ?

Many students attend Miami University for its zoology program, hoping to become a doctor someday, but Joseph Frame has come for a different reason -- to become a vet. "Ever since I was a little boy, I've been interested in animals," Frame said, "but when I grow up, I realized that I didn't want to just take care of dogs and cats. I wanted to work with animals you wouldn't find in your house." Before coming to Miami, Frame worked with his vet Dr. Reid. He learned about the details of being a vet from him. Working with small animals, Frame observed many procedures there. Frame also worked with another vet at Oxford University during his first year at Miami, which involved a leadership position. "I'm in charge of a high school kid," Fram said, "He sometimes needs to be motivated. I like his support system." To realize his goal, Frame began working at the Wilds in Cumberland, Ohio after he met Reid. The Wilds is a non-profit conservation center and is the home for rare and endangered animals. The Wilds combines the concepts of conservation science and education programs to mainly children. After his first year at Miami, Frame began to educate children about the animals. "I think teaching children is an enjoyable experience, especially when they're really interested in animals," Frame said. Frame also explained if a vet school didn't work out, he would be interested in working in animal education. "I would at least have a Zoology degree," Frame said, "The wilds is connected to many zoos all over the country, so I'm sure I can find a job in education." For now, Frame plans to continue working at the wilds this coming summer with a new job at hand, which involves teaching the public about the endangered animals they are protecting and doing shows with owls. While Frame is still an undergraduate student at Miami, he continues his passion for animals. Becoming an exotic vet may be a few years down the road, but Frame continues to work had for this dream, hoping it will become a great reality. What can we know about the Wilds according to the text?

Philip is a school boy. On his twelfth birthday, he decided to give up eating meat. "I don't think it's right to eat animals," he said. "They live on the Earth just like us and they are our friends." Philip's parents were not happy about that. "You are a growing boy," his mother said. "You need meat. Do you want to stay short and be weak?" His mother put some beef, rice and carrots in front of him. "I want you to eat all your food now," she said. "Don't leave anything." Philip didn't want to make his mother sad. But he ate only the rice and the carrots. "You're a silly boy!" said his father. "I'm getting very angry at you." "I'm sorry, Mum and Dad," answered Philip. "I don't want you to be sad or angry. But I really don't want to eat any meat." "Then have some fish, dear," said his mother. "Oh no, I can't!" cried Philip. "Fish are living things too."

MSF stands for Medicines Sans Frontiers. It's also known as Doctors Without Borders . Medicines Sans Frontiers is French. This organization was set up by some French doctors in 1971. Since then, MSF has sent trained doctors all over the world to help people who have suffered from disasters, such as wars and illness. Now, about 3,000 doctors and nurses work for MSF. And over 27,000 doctors have volunteered for MSF so far. The organization received the Nobel Peace Prize in 1999. All kinds of doctors can volunteer for MSF. They need to be ready to go almost anywhere in the world and, of course, they should face difficulties. Most of MSF's work is in Africa. When MSF chooses doctors for a task, they have to go for at least six months. When doctors have completed a few tasks and become experienced, they might be sent on an emergency task following a disaster, such as an earthquake. But why would doctors leave a comfortable life and a good pay to join MSF? Some of them say the experience they have is a great help in their life. And they say that it's great to give others a helping hand. MSF needs support. They get donations from the government and businesses. But 80% of its donations come from doctors themselves.

From babies to body builders, we all have muscles. They grow, they bulge , they stretch they stretch and sometimes they even painfully pull. But for all the work they do for us, we are still unable to crown one as "the strongest muscle." Instead, a few muscles could claim the title, depending on how strength is measured. If the title goes to the muscle that can exert the most force, the victor would be the soleus , according to Gray's Anatomy . Without this muscle, we wouldn't be able to stand, walk, run or shake our bodies on the dance floor. If the soleus was not continuously pulling, we would always be falling over ourselves (although some of us tend to do that from time to time anyway). But perhaps the title should go to the muscle that exerts the most pressure. Pressure is different from force -- pressure takes into account the area over which a force is exerted. The muscle that takes the prize for delivering the greatest amount of pressure is the masseter, or the jaw muscle, according to the book "Clinical Oral Science" (Reed Educational and Professional Publishing, 1998). In 1986, Richard Hofmann of Lake City, Fla., achieved a bite strength of 975 pounds (442 kilograms) for two seconds, setting a Guinness Record. Talk about jaw dropping! The jaw is able to clench and chew because of the masseter muscle. Others may argue the muscles used in childbirth are the most powerful. When it comes to versatility, perhaps the tongue is the strongest muscle. Its combination of elasticity and forcefulness gives us the ability to speak, eat and kiss - all things very desirable on a first date. However dexterous it may be though, its power does not match that of muscles such as the soleus. If slow and steady wins the race, the heart is certainly a _ for the title. When it contracts, the muscle pumps about 2 ounces (59 milliliters) of blood, and is constantly working over a lifetime. Beating about 40 million times a year, a person's heart will beat approximately 2.5 billion times by the time of their 70th birthday. Which would be t he best title for the passage?

Millions of people die of hunger in southern Africa every year, but when Zambia was offered thousands of tons of free maize by the US, the government politely said no. "We don't know whether the food is safe," said Zambia's commerce, Trade and Industry Minister Dipak Patel. His worries are shared by countries around the world that are in two minds about America's genetically modified(GM,)crops.Just last week, EU member nations were discussing whether or not to import GM sweet corn from the US. Ever since people started farming, they have tried to crossbreed plants to make them stronger or better tasting. At one time, only related plants could be crossed with each other. But when GM techniques were developed in the 1970s, scientists were able to put a single gene from a living creature into an unrelated creature. This means they can make crops more productive and resistant to disease by adding genes from other species.They can also create food with special characteristics, such as "golden rice", which is enriched with vitamin A. But many people believe GM foods are a health risk. At the moment, the official argument is that GM foods "are not likely to present risks for human health". But there are still many questions to be answered as the foods are produced in different ways. Some experts believe the genetic material added to plants can transfer to humans and give damage to our bodies. Further harm could be caused by the genes from GM plants crossbreeding with naturally produced crops. People in China are also getting worried about GM foods. More than 70 percent of the country's soybean oil is produced from imported GM soybeans. Meanwhile, an investigation last November found that 12 of 60 famous foods sold across the country were GM products. The government has begun to introduce a marking system for GM goods so that people can choose whether or not to eat them. Which of the following statement is TRUE?

Astronaut Zhai Zhigang became the first Chinese man to walk in space on Saturday, climbing out of prefix = st1 /China's Shenzhou VII spacecraft in a technological feat that made the Chinese people excited. "I'm feeling quite well. I greet the Chinese people and the people of the world," Zhai said as he climbed out of the craft at around 16:40 Beijingtime, a historic achievement telecast live on CCTV. Tens of millions of Chinese viewers gathered before TV screens to watch the moment. Chinese President Hu Jintao and other top leaders had appeared at the BeijingAerospaceControlCenterto watch the live transmission of Zhai's spacewalk. Zhai, 42, chosen by an expert team for the first "extra-vehicular activity". unveiled a red national flag, helped by colleague Liu Boming, who also briefly popped his head out of the capsule. Zhai slowly made his way towards a test sample of solid lubricant outside the capsule, took a sample and handed it to Liu. Zhai safely returned inside the craft after about 20 minutes. The walk marked the high point of China's third manned space journey, which has received widespread media coverage. Zhai wore a$4.4 million Chinese-made suit weighing 120kg. Liu wore a Russian-made one and acted as a back-up. The third crew member, Jing Haipeng, monitored the ship from inside the re-entry module. The risky manoeuvre is a step towards China's longer-term goal of assembling a space lab and then a larger space station, analysts said. "On this flight, Chinese people's footprints will be left in space for the first time," said a commentary by the Xinhua News Agency. The astronauts embarked on their walk after receiving a clean bill of health from doctors on the ground at mission control in Beijing, Xinhua said. Zhai's suit has 10 layers and takes up to 15 hours to assemble and put on. China's first manned spaceflight was in 2003. A second, two-manned flight followed in 2005. The only other countries that have sent people into space are Russiaand theUnited States. According to the text,China's goal of its space program is .

The American political class has long held that higher education is vital to individual and national success. The Obama administration has labeled college as "the ticket to the middle class", and political leaders all have praised higher education as the best way to improve economic opportunity. Yet despite such advice, total college enrollment has fallen by 1.5% since 2012. What's causing the decline? While a shortage of birth in the mid-1990s accounts for some of the shift, big foreign enrollment makes up for that lack. The answer is simple: The benefits of a degree are declining while costs rise. A key measure of the benefits of a degree is the college graduate's earning potential and on this score, their advantage over high-school graduates is fading. Since 2006, the gap between what the median college graduate earned, compared with the median high-school graduate, has narrowed by $1,387 for men over 25 working full time, a 5% fall, women in the same category worse, losing 7% of their income advantage. A college degree's declining value is even more noticeable for younger Americans. According to data collected by the College Board, for those in the 25-34 age range the difference between college graduate and high school graduate earnings fell 11% for men, to $18,303 from $20,623. The decline for women was an extraordinary 19.7%. Meanwhile, the cost of college has increased 16.5% in 2012 since 2006, according to the Office of Labor Statistics' higher education tuition-fee index. Tuition discount from universities has slowed down the rise, but not enough to balance the clear increase adjusted to the inflation . Underemployment has arisen with this situation. The 2013 College Affordability and Productivity Report showed explosive growth in the number of college graduates taking ly unskilled jobs. In 1970 less than 1% of taxi drivers had college degrees. Four decades later, more than 15% do. This is only partly the result of the economic depression and public policies that have failed to produce employment growth. It's also the result of an academic arms race in which universities have spent large sums on elegant dormitories and campus expansion. More significantly, it's the result of sending more high-school graduates to college than professional fields can accommodate. In 1970, when 11% of adult Americans had bachelor's degrees or more, degree holders were viewed as the nation's best and brightest. Today, with over 30% with degrees, a significant part of college graduates are similar to the average American --- not apparently smarter or more well-organized. Declining academic standards and grade inflation add to employers' opinions that college degrees say little about job readiness. Underemployment occurs mainly because _ .

Last month I had a health problem and had to see a doctor. After examining me, The doctor said to me, "The result isn't too bad ." But you must excise often and have healthy food every day. In fact, I'm a lazy person. I never get up early to exercise. And I often have junk food because I like it. In order to be healthy, I decided to change my lifestyle. Now I get up at 6:00 am every day. Then I go out to run for about an hour. I go to a gym on Wednesday and Saturday afternoon. And I hardly have junk food. I have healthy food, like milk and fish. I often eat vegetables and I have an apple every day. You know, " An apple a day keeps the doctor away " I also have about eight glasses of water. And I usually go to bed by ten. All these things make me healthy. Why was I ill?

Which is safer --- staying at home, traveling to work on public transport, or working at the office? Surprisingly, each of these carries the same risk, which is very low.However, what about flying compared to working in the chemical industry? Unfortunately, the former is 65 times riskier than the latter! In fact the accident rate of workers in the chemical industry is less than that of almost any of human activity, and almost as safe as staying at home. The trouble with the chemical industry is that when things go wrong they often cause death to those living nearby.It is this that makes chemical accidents so newsworthy.Fortunately, they are extremely rare.The most famous ones happened at Texas City (1947), Flixborough (1974), Seveso (1976), Pemex (1984) and Bhopal (1984). Some of these are always in the minds of the people even though the loss of life was small.No one died at Seveso, and only 28 workers at Flixborough.The worst accident of all was Bhopal, where up to 3,000 were killed.The Texas City explosion of fertilizer killed 552.The Pemex fire at a storage plant for natural gas in the suburbs of Mexico City took 542 lives, just a month before the unfortunate event at Bhopal. Some experts have discussed these accidents and used each accident to illustrate a particular danger.Thus the Texas City was caused by tons of ammonium nitrate, which is safe unless stored in a great quantity.The Flixborough fireball was the fault of management, which took risks to keep production going during essential repairs.The Seveso accident shows what happens if the local authorities lack knowledge of the danger on their doorstep.When the poisonous gas drifted over the town , local leaders were incapable of taking effective action.The Pemex fire was made worse by an overloaded site in an overcrowded suburb.The fire set off a chain reaction of exploding storage tanks.Yet, by a miracle, the two largest tanks did not explode.Had these caught fire, then 3,000 strong rescue team and fire fighters would all have died. Which of the following statements is TRUE?

Elderly adults who regularly drink green tea may stay more active and independent than their peers over time,according to a Japanese study that covered thousands of people. Green tea contains antioxidant chemicals that may help _ the cell damage that can lead to disease.Researchers have been studying green tea's effect on everything from cholesterol to the risk of certain cancers,with mixed results so far. For the new Japanese study,researchers decided to examine the question of whether green tea drinkers have a lower risk of frailty and disability as they grow older. Tomata and his colleagues followed nearly 14,000 adults aged 65 or older for three years. They found those who drank the most green tea were the least likely to develop "functional disability",or problems with daily activities or basic needs,such as dressing or bathing. Specifically,almost 13 percent of adults who drank less than a cup of green tea per day became functionally disabled,compared with just over 7 percent of people who drank at least five cups fl day. The study did not prove that green tea alone kept people active as they grew older. Green-tea lovers generally had healthier diets,including more fish,vegetables and fruit,as well as more education.lower smoking rates,fewer heart attacks and strokes,and greater mental sharpness. They also tended to be more socially active and have more friends and family to rely on. Although it's not clear how green tea might offer a buffer against disability,Tomata's team did note that one recent study found green tea extracts seem to increase leg muscle strength in older women. While green tea and its extracts are considered safe in small amounts,they do contain caffeine and small amounts of vitamin K,which means it could block drugs that prevent blood thickened. Tomata and his colleagues wanted to _ .

Tattoos and body piercings have moved up on the trend list in recent years. Around Western schools lots of teens are sporting new holes and flesh ink. Like all other subjects, we'll surely be faced with such situation. To get a better view of what has happened in the West, let's sit down and hear what they say. Kerstin Otto from Washington: The hotter it gets and the more layers of clothing disappear, the more tattoos and piercings appear on various places of the human body, I wouldn't be caught dead with a snake tattooed on my ankle or with a piece of metal stuck in my belly button. Erin from Indiana: I think body piercing is cool. In most situations, you don't really have to worry about it getting torn out. I go to Noblesville High School. I am a sophomore (that is the l0th grade). Body piercing can be cool, only if it is not taken to too much of an extent. I would not want to get my nose pierced, just because I think I'll look bad. But that is my personal opinion. I guess that type of thing is a cultural difference. Tiara from Indiana: I personally think body piercing is sickening. If there were supposed to be holes in your body, you would have been born with them. I do, however, think that ear piercing, is not wrong. There is a difference between ear piercing and belly button piercing. Ear piercing is not nearly as dangerous. I would be sick if someone stuck a needle in my belly button. Lee from Illinois: Hi! I live in Illinois. I am 23. I have 12 tattoos and three piercings. I love my tattoos and consider myself an art collector. You would be surprised at who has given me the thumbs-up on my art work. People on the street stop me to look at that on my leg. Most of them don't know what it is. They just think the work itself is great. Subotai from California: I'm not prohibitive of self-expression, but when I see high school students getting these piercings, I really wonder. In some cases, the drive is deeper and darker than mere fashion. A friend of mine tried piercing her own tongue with a safety pin. It got infected and she had a tongue the size of a cow's. Nagib from Washington: I wanted an earring. My friends had them and it looked like a cool thing. I wanted to get a nose ring, but my mum wouldn't let me. Now I'm glad I didn't get it. I just wanted a little stud, but I wouldn't have looked good with it. Jackson from Ohio: I don't think it's wrong, but when people do it all over the place like their face and everything --I think that's ridiculous. People who get the big dragons that cover your whole body--I don't think that's necessary. When I see naked chicks on guys, I think. "You have no respect for women." Brittney from New York: You don't want to do stuff to your body. You don t need to do that because you were made perfect. You don't need to add piercings. If it will make you feel beautiful and you really feel like you need to do it for yourself, then okay. If it really makes a big difference impacting your self-esteem and how you are towards others, then do it. But otherwise, don't mess with what you got. Maybe you should try something more substantial to find beauty in yourself. Who is wholeheartedly lost in tattoos and piercing?

The Chang'e-3, named after a Chinese goddess, is China's first spacecraft to make a soft landing on the moon. It includes a lander and a moon rover called Yutu. The Chang'e-3 spacecraft is the second phase China's lunar rogramme, which includes orbiting, landing and returning to Earth. It follows the success of the Chang'e-1 and Chang'e-2 spacecraft in 2007 and 2010. The launch of Chang'e-3 was successful. The Chang'e-3 is one of the most difficult tasks in China's space programme, the news says. The news adds that exploring the universe and seeking peaceful use of space are dreams of Chinese for thousands of years. With a lander and the moon rover Yutu, Chang'e-3 soft-landed on the moon at 9:11 p.m. Saturday. Yutu later separated from the lander and ran to the moon surface earlier Sunday. China has chosen the name Yutu for its first moon rover, after a worldwide online vote attracted people to come up with names. In Chinese folk tale, Yutu is the white pet rabbit of Chang'e, the moon goddess. Chang'e took her pet and flew towards the moon. She became a goddess and has lived there with the white animal ever since. From this passage, how many spacecraft have flown to the moon successfully.

When Lady Gaga releases a new, pleasing and easily remembered single, it quickly goes around the world. Now scientists have discovered the same thing happens with the songs of another creature----the humpback whale. The mammals become absorbed by new tunes just like people do, and the most popular original whale songs spread globally like hit singles. Male humpback whales are famed for the loud, long and complicated songs they make during the mating season. Each song lasts for 10 to 20 minutes and the males can sing nonstop for 24 hours. At any one time, all the males in a population sing the same song. But a study shows that this song changes over time and spreads around the oceans. Dr. Ellen Garland of Queensland University, said: "Songs move like cultural communication from one population to another, causing all males to change their song to a new version." Researchers recorded songs from six neighboring populations of whales in the Pacific over a decade. They found that new versions of the songs appear over time and always spread from west to east. It takes two years for songs that appear in the waters off Australia to be heard in French Polynesia. Most of the new songs contain material from the previous year mixed with something new. " It would be like getting an old Beatles song together with U2," she said. " Occasionally they completely throw the current song out of the window and start singing a completely new song". Dr. Garland believes that a small number of whales may migrate to other populations carrying the new songs with them, or that they are heard by passing whales. The researchers suspect whales adopt new songs to make themselves distinct. Dr. Garland said: " we think this male search for new songs is in the hope of being that little bit different and perhaps more attractive to the opposite sex." According to the text, we can learn that _

When did you see a polar bear ? On a trip to a zoo, perhaps ? If you had attended a winter activity in New York a few years ago, you would have seen a whole polar bear club. These "Polar Bears" are people who meet frequently in the winter to swim in freezing cold water. That day, the air temperature was 3 degrees. And the water temperature was a little higher. The members of the Polar Bear Club at Coney Island, New York are usually about the age of 60. Members must satisfy two requirements. First, they must get along well with everyone else in the group; this is very important because there are so many different kinds of people in the club. Polar Bears must also agree to swim outdoors at least twice a month from November through February. Doctors don't agree about the medical effects of cold-water swimming. Some are worried about the dangers of a condition in which the body's temperature drops so slow that finally the heart stops. Other doctors, however, point out that there is more danger of a heart attack during summer swimming because the difference between the air temperature and the water tempreature is much greater in summer than in winter. The Polar Bears themselves are satisfied with the benefits of cold-water swimming. They say that their favorite form of exercise is very good for the circulatory system because it forces the blood to move fast to keep the body warm. Cold-water swimmers usually turn bright red after a few minutes in the water. A person who turns blue probably has a very poor circulatory system and could not try cold-water swimming. The main benefits of cold-water swimming are probably mental. The Polar Bears love to swim all the year round; they find it fun and relaxing. As one 70-year-old woman says, "When I go into the water, I pour my troubles into the ocean and let them float away." Doctors _ .

ARE you creative, shy, outgoing? Our personalities reveal a lot about who we are. But what's surprising is that our personality can also say something about our health. That's according to researchers at Duke University, US. During an experiment on 1,000 people, scientists assessed their personalities in two ways: by asking someone they knew, such as a family member or friend; then by asking someone they had just met, such as a nurse. The study found that those who were careful at age 26 were in better health after 12 years. Being careful means that people tend to have a lot of self-control, and are less likely to smoke, the scientists said. Careful people are also more likely to have an active lifestyle and healthy diet. From those who were least careful, 45 percent developed health problems by the age of 38. Such health issues included gum disease and high blood pressure . To compare, only 18 percent of careful people went on to develop health problems. Another positive personality was called "openness to experience", meaning curious and imaginative. People who have more of this personality have higher IQ scores. So they'd be more likely to know how to find medical help to prevent disease. According to the report, if doctors assessed our personalities, it could help doctors to find which young adults need advice on how to live a healthy lifestyle. What's surprising is that stress didn't play a big part on a person's health. Even though stress and anxiety are usually linked to bad health. But can a doctor who knows our personality really improve our health? Or should doctors be kept away from knowing something so personal? Which personality type may be better for our health, according to the research?
