Which _ is the most talkative? No matter what you answer, you are partially right. A recent Gallup Poll show that both man and women believe that women possess the gift of talking and some even believe women are biologically built for conversation, but all of this is challenged in research published in the November issue of "Personality and Social Psychology Review". In recent research by Campbell Leaper and Melanie Ayres, they collected all of the available evidence from decades of scientific study and systematically combined the findings into an overall picture of the differences between men and women regarding talkativeness. They found a small but reliable tendency for men to be more talkative than women in certain cases, such as when they were conversing with their wives or with strangers. Women talked more to their children and to their college classmates. The type of speech was also explored in the research. The researchers discovered that, with strangers, women were generally more talkative when it came to using speech to ensure her connection to the listener, while men's speech focused more on an attempt to influence the listener. With close friends and family, however, there was very little difference between genders in the amount of speech. Talking with strangers, _ .

When a person travels over long distances, the place may not be the only change. When his or her body rhythms get thrown off, he or she suffers from jet lag -- it's hard to sleep and eat at the right times in the new location. Humans and animals have a biological clock in their body that tells them when to sleep, and when to wake. When someone comes to a different place far away, this biological clock takes a while to match the day and night time of the new place. In a new study, reported in November's Science News, researchers at the University of California, Berkeley tested the effects of jet lag on hamsters . They wanted to know how serious jet lag would affect the brain and thinking habits of the animals. They think what happens to hamsters may happen to humans, too. In their experiments, the researchers first moved the hamsters' schedules forward by six hours. The animals' eating schedules, for example, were changed. If a hamster was often fed at noon and 4 pm, then it ate at 6 pm and 10 pm on the new schedule. People who travel from China to Europe experience the same shift, since the two regions are about six hours apart, half the shift between China and the USA. After three days, the scientists did it again - they shifted the hamsters' schedules forward by another six hours. Three days after that, they did it again; and then again three days later. For a full month, the scientists changed the hamsters' routines every three days. During the study, the hamsters slept the same amount every day as they did before the study. However, their sleep patterns had a hard time keeping up with the changing schedule. What's more, they seemed to feel low. The researchers also found that the hamsters had trouble with basic learning exercises during the study. The animals' thinking problems didn't go away when the experiment was over. A month after they went back living on a normal schedule, the hamsters still had trouble with basic mental tasks, such as learning and memory. The scientists concluded that serious jet lag has serious side effects, including stupidity . They are now trying to find out how jet lag is causing these problems, and then it will be possible for them to work out a solution. What time is it in France when it is 2 pm in China?

American researchers have developed a technique that may become an important tool in fighting AIDS virus from attacking its target-cells in the body's defense system.When AIDS virus enters the blood,it searches for blood cells called T4 lymphocytes .The virus connects to the outside of T4 lymphocytes.Then it forces its way inside.There it directs the cells' genetic material to produce copies of the AIDS virus.This is how AIDS spreads. Researchers think they may be able to stop AIDS from connecting to T4 ceils.When AIDS virus finds a T4 cell,it actually connects to a part of the cell called CD4 protein. Researchers want to fool the virus by putting copies or clones of the CD4 protein into the blood.This way the AIDS virus will connect to cloned protein instead of the real ones.Scientists use genetic engineering methods to make the clones.Normally a CD4 protein remains on the T4 cell at all times;the AIDS virus must go to it. In a new technique,however,the cloned CD4 protein is not connected to a cell.It floats freely,so a lot more can be put into the blood to keep the AIDS virus away from real CD4 protein on T4 cells.One report says the.AIDS virus connects to cloned protein just as effectively as it connects to real protein.That report was based on tests with blood cells grown in labs.The technique is just now beginning to be tested in animals.If successful,it may be tested in humans within a year. When the AIDS virus enters the blood,it is reproduced by _ .

Living a healthy lifestyle lies in forming the right eating habits. Here are some of the good habits you can develop when it comes to healthy eating. Drink plenty of water. You must drink at least 8 glasses of water a day. You may need even more water if you are in a hot environment or if you are exercising. Eat breakfast. Breakfast is the most important meal of the day. A recent study has shown that those who eat breakfast will consume an average of 100 calories less during the day than their colleagues who skipped breakfast. They will also be able to concentrate better. Don't skip lunch. If you do so, your blood sugar level will drop and your metabolism will slow down. When you get home you are starving and eat everything you can find. We all need to snack from time to time, but please choose your snacks carefully. In fact, it's a good idea to eat two healthy snacks besides your three main meals. Choose healthy snacks like fruits and vegetables, low fat yogurt, cottage cheese with apple sauce, and so on. Eat your fruit and vegetables. We should eat at least 5 servings of fruits and vegetables a day. Take a piece of fruit for a snack, add some banana and _ to your favourite breakfast cereal, have a salad with lunch, and eat at least one vegetable at dinner each night. Do not eat your dinner too late. Try to eat dinner at least 3 hours before you go to bed. This will give your body a chance to digest most of the food before you rest for the next 8 hours. Plan dinner for the week ahead of time and make sure you have everything you need in the house so other family members can get a head start on dinner if you have a late meeting at the office. Who is this passage intended for?

For most Chinese university students, the prefix = st1 /USis a favorite destination for further education. But apart from obstacles such as the GRE and TOEFL exams, choosing a good graduate school is no easy task. Admission is very competitive for international students, so it is important to apply to a number of institutions to have a reasonable chance of acceptance. Since the application to most universities requires a certain fee, Chinese students usually choose seven to 17 universities according to their own financial circumstances. Wang Yuwei, a Zhejiang University graduate, sent applications to 15 USuniversities. When the 24-year-old began looking for a USgraduate school in her senior year, she took time to compare the various schools and find the ones most suiting her needs. Now, studying at theUniversityofWashington, she knows that her hard work paid off. "To broaden your chances, at least one third of the applications should be to less selective schools," said Wang. "Applicants shouldn't limit their choices to the most famous institutions." Furthermore, one shouldn't rely on too much on college rankings such as the Gorman Report or US News & World Report's annual league tables. The right school is the one that best meets your own personal needs and interests, rather than someone else's assessment of an institution's prestige . "Usually choices are based on one's personal interests and academic background, but it is important to make sure that your chosen subject is satisfied," said Wang. The author believes that the right school is the one that _ .

We all know that food gives us energy, but sometimes it can make us much happier when we feel bad. Studies show that foods such as sea fish, bananas, pumpkins and chicken can help fight against bad moods. How can they affect our moods? Studies show that people living by the sea appear much happier than other people, because the fresh sea air helps them clear their minds and they eat a lot of sea fish. Bananas have something that is full of Vitamin B6. Having more bananas can help us make a quick decision, and become more confident. Eating pumpkins can also help people get into a good mood because it's rich in Vitamin B6 and iron and it will make us happier. Are you in a bad mood? If you are , don't sit alone. Go to eat such happy food with your friends. Maybe you'll be better. What food can make us more confident?

A young man from a village called Nawalapitiya married a young woman from Maliyuwa, a nearby village. They lived with the man's big family--his parents, his brothers, their wives and children. The family kept an elephant, in which the young woman soon took a great interest. Every day she fed it with fruit and sugar. Three months later the woman went back to her parents' home, having quarreled with her husband. Soon the elephant refused to eat and work. It appeared to be ill and heart-broken. One morning after several weeks the animal disappeared from the house. It went to the woman's home. On seeing her, the elephant waved its trunk and touched her with it.

The Morning After Robot From today's newspaper, I know that in 2014 you might get a Morning After Robot. It will clean your house after a party. The Robot can take picture of your room before the party. After the party, the robot will go around the room, and it will pick up bottles and trash. After that it will compare the room with the picture and put things back according to its original shape. Such robots are being studied in a lab at Stanford University. That sounds pretty cool! If we can see the robot and have enough money, we must buy them. Robot Roomba Mothers' Day is coming. You can give Robot Roomba as a gift to your mother. The Roomba is a great gift for two reasons. On the one hand, it's really cool as a useful robot. It can actually clean your floor. Maybe not as fast or well as a person does, but it is a lot more fun cleaning the floor by the Roomba than cleaning the floor yourself. On the other hand, it shows the family life is very modern.

People eat different things in different parts of the world. In south China we eat rice every day. Sometimes we eat it two or three times a day, for breakfast, lunch and supp-er. We usually eat it with fish, meat and vegetables. The Japanese eat rice, too. They also eat a lot of fish. They sometimes eat raw fish. In Africa, maize is the most important food. People there make maize into flour .From this flour they make different kinds of bread and cakes. In western countries such as Britain, Australia and the U.S.A, the most important food is bread or potatoes. People there usually make their bread from wheat flour. They cook the potatoes in different ways. In England the most popular food is fish and chips. Sometimes people cook this food at home, but usually they buy it at the shop. They eat this food at home, in their work place, in the park or on the road. People call it "take-away" food. The most important food for African people is _ .

I was born in Brooklyn. My father was a small-business man and we never had much money. He supported the family, moved us to Merrick on Long Island, when I was 11. He just recently died at age 96. He was still driving and playing golf right to the end. He was the only guy I knew who at age 90 could shoot under his age. I guess that taught me something about perseverance. I went to the University of Michigan as an engineering student in 1960. I was standing outside the student union building when Senator John F. Kennedy made a campaign speech that essentially announced his plan for the Peace Corps. He talked about how students could provide service for the country. It was an important moment for me. After I graduated, I worked as a computer programmer for I.B.M. for two years. By then, the Vietnam War was in full swing and the draft had accelerated. I didn't agree with the war and was interested in finding alternatives. I.B.M. applied for a delay for me twice but the application failed. I went to work at M.I.T.'s Instrumentation Labs on a project designed to create a rescue vehicle for lost submarines . I thought this job would keep me out of the draft, but M.I.T. hadn't put in the proper paperwork and I got called in for my physical. The day before my physical, I broke my ankle playing tennis and, of course, my draft board didn't believe a word of it. I had to provide X-rays. I had tears in my eyes from the pain, but a smile on my face. I started John Snow Inc. in 1978 (Dr. Snow is considered the father of modern epidemiology because he traced the source of a cholera epidemic in the 1850s). We had a very clear vision of what we would be. It would not be about making the most money but having the most impact. My goal was to attract talented people who had that passion to focus on primary care, women's health, child health, and to do great work. I also run a nonprofit called World Education, which focuses on literacy. What motivates me is going to the field, either in the United States or overseas, and seeing the people whose lives we affect. I didn't grow up rich but had the advantage of growing up in the United States and getting a good education. I couldn't have started J.S.I. in many other places. And I believe there is a duty to try and assist people who are struggling against tough situations. According to the passage, we know that _ .

Developing healthy eating habits starts from childhood, therefore it is important for parents to teach and provide children with a healthy diet. DPHSS administrator of the Bureau of Nutrition Services, Charlie Morris told KUAM News, "A healthy diet for a child consists of a lot of fruits and vegetables in the diet limiting the amount of simple sugars in the diet and high fat food and highly processed food." This means staying away as much as possible from food such as chips, cookies, candies and sugary drinks, as all children need to have meals which involve a well-balanced diet. Community nutritionist Thelma Romoso said, "The fruit, the vegetable, the grain, the protein, and also the milk, the diary product, so for the fruits it's easy for a mother to go into the two plus three concept of fruits and vegetables or five a day." This concept means that there are at least two servings of fruits a day, three servings of vegetables a day which can be served for lunch and dinner. As for protein parents can make a variety of dishes from chicken, beef, fish or even dried beans to pledge the child gets three servings a day. Morris said that the child's hunger level controls how much is eaten and the parent controls what and when the meal is offered, saying, "Mom needs to ensure that the food offered is good food for the child to eat and throughout the day depending on how active they are, snacks are not a bad thing, so the mom should offer good kinds of snacks." When it comes to preparing your child's lunch and snacks for school, make sure to keep in mind that the food you provide should not only be a source of energy but also be nutritionally beneficial such as fresh fruits, and whole grain bread. But parents must be sure to remember that a good nutritional diet must be balanced with physical activity, namely it is important that children get outside and run around and play and get activity in addition to eating a good diet. What does the author intend to tell us in the passage?

Reseachers at the University of Kansas say that people can accurately juage 90 percent of a stranger's personality simply by looking at the person's shoes."Shoes convey useful information about their wearers,''the authors wrote in the new study published in the Journal of Research in Personality. Lead researcher Omri Gillath said the judgments were based on the style,cost,color and condition of someone's shoes.In the study,63 University of Kansas researchers looked at pictures showing 208 different pairs of shoes worn by the study's participants.Volunteers in the study were photographed in their most commonly worn shoes,and then filled out a personality questionnaire. Some of the results were expected:People with higher incomes most commonly wore expensive shoes,and flashier shoes were typically worn by outgoing people.However,some of the more specific results are strange enough.For example,"practical and functional'' shoes were generally worn by more "pleasant" people,while ankle boots were more linked with ''aggressive'' personalities.The strangest of all may be that those who wore' 'uncomfortable looking" shoes tend to have "calm" personalities.And if you have several pairs of new shoes or take extreme care of them,you may suffer from "attachment anxiety",spending lots of time worrying about what other people think of your appearance.There was even a political calculation in the mix with more liberal types wearing "shabbier and less expensive" shoes. The researchers noted that some people will choose shoe styles to mask their actual personalities,but researchers noted that volunteers were also likely to be unaware that their footwear choices were showing the deep side of their personalities. Which of the results is beyond people's expectation?

The message what the "Eat up All on Your Plate" campaign tries to convey is not new. Our ancestorshad poems about the importance of frugality in the consumption of food. But it makes a lot of sensewhen many are yet to have the awareness that food waste borders on a crime. The campaign has been started online and thousands of people have answered the call. Manyrestaurants have joined the program by announcing that customers are encouraged to order half a dish andtake home what they can't finish. However, it is estimated that 50 million tons of grain are wasted every year in China, enough tofeed 200 million people for a year. True, official banquets paid with public money contribute much to such waste. But it isimportant that everyone thinks about how they can do their bit to reduce food waste. We need to developthe habit of never ordering or cooking more than we can eat and feeling guilty when we dump ourleftovers. Many people have a bad habit of entertaining guests with more than enough food, believing that theyhave not satisfied their guests' appetites if there is no food left on the table. In fact, to be a good host theyorder more than their guests can possibly eat and their guests eat more than they want out of politeness. Such a mentality needs to change. People need to be made aware that it is impolite to force guests toeat more than they are comfortable with and it is insensible and uncivilized to waste food. Even if one iswealthy, ordering more than one can eat is a bad way to show off one's wealth. The problem of food waste can be handled only when _ .

Preface to the fourth edition A practical English Grammar is intended for intermediate and post-intermediate students. We hope that more advanced learners and teachers will also find it useful. The book is a comprehensive survey of structures and forms, written in clear modern English and illustrated with numerous examples. Areas of particular difficulty have been given special attention. Differences between conversational usage and strict grammatical forms are shown but the emphasis is on conversational forms. 1. Explanation and examples have been brought up to date. 2. There is now more information on countable and uncountable nouns, attributive and predicative adjectives, adverbs of places, sentence adverbs, cleft sentences, prepositions, conjunctives, modal verbs, perfect tenses, infinitive constructions, the passive, purpose clauses and nouns. In the fourth edition the main changes are as follows. 3. Some material has been rearranged to make comparisons easier. For example, parts of chapters on can, may, must etc. are now grouped by functions; verbs of liking and preference have a chapter to themselves; suggestions and invitations have joined the chapter on commands, requests and advice. 4. The contents list now summaries every edition heading, and there is a new index containing many more entries references. In this edition the sign "~" is frequently used to show a change of speaker in examples of dialogue. Note also that although the sign "="sometimes connects two words or expressions with the same meaning, it is often used more freely, e.g. to indicate a transformation from active to passive or direct to indirect speech. We wish to thank all at Oxford University Press who have assisted in the preparation of the fourth edition. We would also like to thank Professor Egawa of Nihon University, Japan, Professor Rene Dirven of Duisburg University, West Germany and other colleagues for their friendly and helpful suggestions.

The program is introduced by Fran Levine. 9:00 PM Discovery When a 10 -year -old boy gets a first class degree in mathematics or an 8-year- old plays chess like a future grand master, they are considered as geniuses. Where does the quality of genius come from? Is it all in the genes or can any child be turned into a genius? And if parents do have a child who might become a genius in the future, what should they do ? In this 30-minute film, Barry Johnson, the professor at School of Medicine, New York University will help you discover the answer. 10:00 PM Science/Health Is it possible to beat high blood pressure without drugs? The answer is "yes", according to the researchers at Johns Hopkins and three other medical centers. After a study of 800 persons with high blood pressure, they found that after 6 months, those devoted to weight-loss exercise and eating a low-salt, low-fat food lost about 13 pounds and became fitter. Plus, 35% of them dropped into the "normal" category. This week, Dr. Alan Duckworth will tell you how these people reduce their blood pressure to a level similar to what's achieved with Hypertension drugs. From Outlook, you can get a great deal of information about _ .

What we eat, when we eat or how we eat is usually considered to be an everyday eating habit. Good eating habits are very important for our health. Most of us would rather eat sweets and ice-cream than meat and rice. Sweets and ice-cream are not bad for the stomach if we eat them at the end of a meal. But we should also know that if we eat them before a meal, they will spoil our appetite . It is a good habit for us to eat our meal at the same time each day. When we feel hungry, it is a sign that our body needs a good supply. When we feel angry or excited, we may not want to eat. A long time ago, in England some judges used to decide whether a man was telling the truth by giving him some dry bread. If he could not swallow the bread, it was a sign that he wasn't telling the truth. He was telling lies. Although this seems very strange and rather foolish, it is indeed an excellent way of finding out the truth. A man who is worrying about something has difficulty in swallowing anything dry. Because he is worrying, he loses his appetite and does not want to eat. Why do we have to develop good eating habits? Because _ .

Qian Xuesen is one of the greatest scientists who devoted all their lives to China's science and technology. In 1911, he was born in Hangzhou, eastern China. Qian received a mechanical engineering degree in 1934 in Shanghai and went to the United States on a scholarship to study aeronautical engineering at MIT at the age of 23. As a student at MIT, and later as a scientist and teacher at the California Institute of Technology, Mr.Qian played a central role in early United States' efforts to develop jet aircraft and rocketry technology. Mr. Qian served on the United States government's Science Advisory Board during World War II. His teacher and colleague, the Caltech physicist Theodore von Karmon, praised him as "a brain whose work will change the world greatly". In the 1940s Qian wrote an article for a famous magazine on a winged space plane that led to develop NASA's new space shuttle. In 1955 he came back to his motherland from the US. Under his leadership, China produced its first missile called Long March, and in 1970, launched its first satellite. He was considered as the father of the country's first ballistic missiles, first satellite and the Silkworm anti-ship missile. In 2009, he died in Beijing. Qian Xuesen was a _ , when he was at MIT.

The world's biggest Internet search engine, Google, has proven once again to be King of the Web. Users can download "Google Wi-Fi" software and then enjoy free Wi-Fi service available in some US cities since last Tuesday. Wi-Fi is short for "Wireless Fidelity" . It allows laptop computers and personal digital assistants to the Internet at high speed by radio signal. A person with a Wi-Fi enabled computer can connect to the Internet when near one of the network's access points. The place covered by one or several access points is called a hotspot. Google has already set up two "hotspots" in the US city of San Francisco which provide a free Wi-Fi service. The Wi-Fi technology even allows users to enjoy a free Internet phone service. Some scientists argue that Wi-Fi may replace mobile phone networks. Wi-Fi is still limited to a few cities, where there are "hotspots". But its capability of sending information has already done better than that of the mobile phone network, even that of 3G(Third Generation Telecommunication Technology). Some scientists have started to call Wi-Fi 4G. In addition to a high speed Internet connection, Wi-Fi has other advantages compared to mobile phones. Wi-Fi is global. The same Wi-Fi system works in different countries around the world. Different from using cell phones, you don't need to change computers to use Internet phones when you go to other places and most importantly, many Internet phones cost you nothing at all.

Computers can help many workers. They can also help thieves. There was one thief who worked in a bank of the United States. He paid for everything he needed by check . Then he told the computer not to take any money from his account for the checks he wrote. The bank's computer did what he said. And it did not take any money from his bank account. One day the computer broke down. People had to do the computer's work. They soon found out what was happening. Another thief, who worked for a bank saw people filling in deposit forms . Many of these people did not know their account numbers, so they wrote only their names on the forms. They left empty places for their account numbers. The thief wrote his own account number in this place. When the computer read these forms it looked only at the account numbers. It did not look at the customers' names. It paid the money on these deposit forms into the thief's account . Then there was the bank worker who told the bank computer to take ten cents off every customer's account each month and put it into his own account. For a long time the bank's customers did not notice that they were losing ten cents every month. But then someone did notice and told the bank. That was the end of that little game!

More and more, the operations of our businesses, governments, and financial institutions are controlled by information that exists only inside computer memories. Anyone clever enough to modify this information for his own purposes can get big reward. Even worse, a number of people who have done this and been caught at it have managed to get away without punishment. It's easy for computer crimes to go undetected if no one checks up on what the computer is doing. But even if the crime is detected, the criminal may walk away not only unpunished but with a glowing recommendation from his former employers. Of course, we have no statistics on crimes that go undetected. But it's disturbing to note how many of the crimes we do know about were detected by accident, not by systematic inspections or other security procedures. The computer criminals who have been caught may have been the victims of uncommonly bad luck. Unlike other lawbreakers, who must leave the country, commit suicide, or go to jail, computer criminals sometimes escape punishment, demanding not only that they not be charged but that they be given good recommendations and perhaps other benefits. All too often, their demands have been met. Why? Because company executives are afraid of the bad publicity that would result if the public found out that their computer had been misused. They hesitate at the thought of a criminal boasting in open court of how he juggled the most confidential records right under the noses of the company's executives, accountants, and security staff. And so another computer criminal departs with just the recommendations he needs to continue his crimes elsewhere. What may happen to computer criminals once they are caught?

Americans eat breakfast and lunch quickly unless it is a social business or family occasion. The evening meal is usually longer and a time for families to gather together. Rushing through daytime meals is part of the fast pace in America. Another reason for rushing through daytime meals is that many people eat in restaurant that are usually crowded with people waiting for a place so that they can be served and return to work at the proper time. So each one hurried to make room for the next person. As there are busy people everywhere, there is a real difference with meals that are eaten in a hurry and those that can be enjoyed slowly with friends.

On Tuesday,a new study published in the American Heart Association's journal Circulation:Heart Failure revealed that women who ate five or more dishes of baked fish a month had a thirty percent lower risk of heart failure in comparison to women who ate less than one dish a month. Researchers examined the diets of 84,493 women,whose ages ranged from 50 to 79.The women who had eaten lots of baked fish like salmon ,were more healthy than those who mostly ate tuna or white fish. Eating baked fish also appeared to provide a protection against high blood pressure. The study also found that those women who ate more baked fish were likely to have a lower weight,exercise more and eat more fruits and vegetables in comparison to those who ate fried fish. Researchers noted that past research had discovered the fatty acids in fish probably decreased the risk of high blood pressure by improving blood pressure along with heart and blood functioning. This study showed the link between eating fish and heart failure risk but it was not designed to show cause and effect. This study also showed that just by eating one dish of fried fish a week led to a 49% greater risk of heart failure,and eating fried fish led to lower fiber intake and higher calorie intake. The American Heart Association suggested eating a minimum of two dishes of fish especially fatty fish each week. According to this passage,which one is correct?

You may have heard about the many benefits of yoga, but a recent New York Times story, has stirred up more than a little controversy in the yoga community. "How Yoga Can _ Your Body," by science writer William J. Broad, quotes a long-time yoga teacher who "...has come to believe that 'the vast majority of people' should give up yoga altogether. It's simply too likely to cause harm." He goes on to describe a number of cases where people have been injured doing yoga, including himself. The research in the article isn't groundbreaking: doing any form of exercise you could potentially hurt yourself. If you look at the injury rates of other physical activities, the number of injuries sustained from yoga would pale in comparison. Practicing yoga is just like anything in life: You have to push yourself in order to grow. But you also have to know your limits and when you're breaking them. If you stick to your comfort zone, you'll never be able to increase your flexibility. If you push to the point where you're not only uncomfortable, but in real pain, you'll likely injure yourself. The reasons that yoga causes "serious injury", according to the Times story, range from students' physical weaknesses to inexperienced teachers pushing too hard to the growing number of inflexible "urbanites who sit in chairs all day" trying hard to twist themselves into difficult postures. Yoga is called a "practice" for a reason. You don't have to be perfect. You don't have to tackle every pose. It doesn't matter if you can touch the floor with your palms during your first forward bend or your thousandth, or if you never get there. We go to the mat to learn to better listen to what our bodies are telling us, and to better hear that quiet inner voice drowned out by the noise of our busy lives. It's a shame to discourage the majority of people from practicing yoga and missing out on all of the mind-body benefits that going to the mat has to offer. Which is not mentioned among the reasons for yoga being likely to cause injury?

A primary school in Wuhan has used new desks and chairs to prevent students from getting short sight. The desks and chairs make students have the correct posture, especially when reading and writing. Each desk has an adjustable steel bar. The bar can help students keep their eyes at least 30cm from books. Zhang Jianming is headmaster of the primary school. She said the new desks and chairs were provided by an eye care centre in the city. The school carried out a survey last September. It showed that about 7 percent of its 1,093 students said they suffered from short sight. The new desks and chairs have already improved the students' posture, but both teachers and students might need more time to get used to them. Yang Lihua is head of the Wuhan Youth Eye Care Center. She said the desks and chairs were introduced to 19 schools on a trial basis. "During our research into short sight, we noticed that the number of students with short sight was increasing. This is because parents are teaching their children to read and write at a very early age without paying enough attention to their posture," she said. Feng Junying is a doctor at Beijing Jingshan School. "I think the new desks and chairs in Wuhan will certainly be helpful," she said. "But bad reading habits at school are not the only reason for short sight. Children are using mobile phones and iPads when they are very young. This can be another reason for short sight at a young age." According to the passage, the adjustable steel bar can help the students keep their eyes _ from books.

Too much TV-watching can harm children's ability to learn and even reduce their chances of getting a college degree, new studies suggest in the latest effort to examine the effects of television on children. One of the studies looked at nearly 400 northern California third-graders. Those with TVs in their bedrooms scored about eight points lower on math and language arts tests than children without bedroom TVs. A second study ,looking at nearly 1000 grown-ups in New Zealand, found lower education levels among 26-year -olds who had watched lots of TV during childhood. But the results don't prove that TV is the cause and don't rule out that already poorly motivated youngsters may watch lots of TV. Their study measured the TV habits of 26-year-olds between ages5 and 15. These with college degrees had watched an average of less than two hours of TV per week night during childhood, compared with an average of more than 2 1/2 hours for those who had no education beyond high school. In the California study, children with TVs in their rooms but no computer at home scored the lowest while those with no bedroom TV but who had home computers scored the highest. While this study does not prove that bedroom TV sets caused the lower scores, it adds to accumulating findings that children shouldn't have TVs in their bedrooms According to the California study, the low-scoring group might _ .

Colleges may try to do a lot to prepare students for study abroad - telling about culture shock, warning about homesickness, recommending books about the country. But when it comes to adjusting to campus life when they return, schools haven't done as much, even though the transition is sometimes almost as difficult. "They can feel disoriented and depressed. They find things are not exactly the way they were when they left," said Antonio Jimenez, director of the Center for International Affairs at California State University Channel Islands in Camarillo, California, US. "They find that people don't care much about their experiences." Some colleges are now rethinking their approach to study abroad, recognizing that students might need almost as much help adjusting to life back home as they did getting ready to leave: students experience a sort of reverse culture shock when they return to the US. They might be troubled by the wealth and waste they see back home or they might feel homesick for their new country and its customs. And when they try to talk about their experiences, people quickly lose interest, especially if they haven't lived abroad themselves. Down the road, they also might find it difficult to translate their time abroad into experience that an employer finds attractive. Some California universities have organized conferences to help students make the most of their time abroad. During a one-day event, students learn how to adjust after living abroad, talk about their experiences and incorporate them into their lives and future careers. Blythe Cherney, 22, a senior who has studied in Thailand and Britain, found the _ helpful. "Any experience abroad does have an effect on you," Cherney said. "When you come back, it's important to talk about it, especially with people who know what you've been through." Yet most universities focus more on preparation than reorientation. When students return, they might have a welcome home reception. But for the most part, universities figure students can fend for themselves. The wrier is _ the help colleges offer for the students when they return from studying overseas?

Teachers and parents usually call attention to the pictures when they read storybooks to pre-school children. But a new study suggests that calling attention to the words and letters on the page may lead to better readers. The two-year study compared children who were read in this way in class with children who were not. Those whose teachers most often discussed the print showed clearly higher skills in reading, spelling and understanding. These results were found one year and even two years later. Shayne Piasta, an assistant professor of teaching and learning at Ohio State University, was an author of the study. She says most pre-school teachers would find this method manageable and would need only a small change in the way they teach. They already read story-books in class. The only difference would be increased attention to the printed text. "If you get children to pay attention to letters and words, it makes sense that they will do better at word recognition and spelling." But she says research suggests that very few parents and teachers do this in a systematic way. More than 300 children aged four and five were observed in classrooms. They came from poor families and were below average in their language skills. For thirty weeks, the children took part in a program called Project STAR--- Sit Together and Read. The project is based at Ohio State. It tests the short-term and long-term results of reading regularly to pre-school children in their classrooms. There are different ways that adults can talk to children about print. They can point to a letter and discuss it, and even trace the shape with a finger. They can point out a word and discuss the meaning of the print or how the words tell the story. And they can talk about the organization of the print--- for instance, showing how words are written left to right in English. What do we know about the ways pre-school children are usually taught?

[
"More attention is paid to the pictures ,with words and letters being ignored.",
"Preference is given to the shape of letters and the organization of the print.",
"The focus of the teaching is on bringing them up to be good readers.",

Feel tired lately? Has a doctor said he can't find anything wrong with you? Perhaps he has sent you to a hospital, but all the advanced equipment there shows that there is nothing wrong with you. Then, consider this: you might be in a state of sub-health. Sub-health, also called the third state or gray state, is explained as a borderline state between health and disease. According to the investigation by the National Health Organization, over 45 percent of sub-healthy people are middle-aged or elderly. The percentage is even higher among people who work in management positions as well as students around exam-week. Symptoms include a lack of energy,depression,slow reactions,insomnia,anger,and poor memory.Other symptoms include shortness of breath,sweating and aching in the waist and legs. The key to preventing and recovering from sub-health,according to some medical experts,is to from good liwing habits,alternate work and rest,exercise regularly,and take park in open air activities. As for meals,people are advised to eat less salt and sugar.They should also eat more fresh vegetables,fruits,fish because they are rich in nutritional elements--vitamins and other elements that are important to the body.Nutrition experts point out that it is not good to eat too much at one meal because it may cause unhealthy changes in the digestive tract. They also say that a balanced diet is very helpful in avoiding sub-health. The key to preventing you from falling into a state of sub-health is that you should _ .

Cars are lots of fun, but they could also be dangerous. We have to be careful when we drive them or ride in them. It's always a good idea to put on your seat belt when you're in a car. Why? Think about this example: You put an egg on a skateboard and give it a push. If the skateboard hits a stone, it will stop, but the egg won't. It will fly through the air, hit the ground and break. Now, think what would happen if you tied the egg to the skateboard. When the skateboard hits a stone, the egg won't go flying; it will stay safely on the skateboard. Volvo, a famous Swedish carmaker, was the first to use seat belts in 1849. Air bags are also very important for car safety, because sometimes a seat belt isn't enough. If the car is going really fast and runs into something, seat belts could even hurt the people who wear them. Most new cars have air bags in front of and next to the seats. When a car hits something, its air bags will come out quickly in less than one second to keep the people inside safe. The passage mainly tells us _ .

What is the hottest topic at your school recently? In Taiyuan No.55 Middle School, it's money. The school held an activity called "making money" last weekend. About 200 Junior 1 and Junior 2 students were divided into 30 teams. They went out to make money by selling things. What did they choose to sell? Some sold newspapers; some chose bottled water; some sold environmentally friendly shopping bags and bamboo baskets. Hu Qing's team decided to sell some useful books in front of the Children Activity Center. They thought parents would like to buy the books for their children. But unfortunately, they met urban management officers . The officers asked them to leave. "We played hide-and-seek with the officers for the whole morning" said Hu. "Finally we had to give up." Wang Bing and her team sold ice cream in a square. They didn't meet any officers. But few people were interested in what they were selling. The team then put up a board saying "For Country Kids". It worked. More people came to their stall . A foreigner even gave them 100 yuan. "He didn't want any change. He said he wanted to help the children," said Wang. "We were touched." Later that day they gave the 100 yuan and more to the "Project Hope" office. Meng Zhaoxiang and his team were luckier. They sold all their cakes in four hours, spending 39.5 yuan and getting back 80 yuan. They made 40.5 yuan. "It was not easy to make the money," said Meng. "Some people just looked. Others just tasted but didn't buy. Now I know how hard it is for our parents to make the money we need to lead happy lives." According to the passage the students learn _ .

AIDS' Threat to Asia Grows NEW DELHI----Just a few years ago, Mala was a typical middle-class Indian housewife. She cooked, cleaned and looked after her two small children. Last year, her life took a tragic turn. Her husband died of AIDS; she was found out HIV-positive and her mother-in-law took her children away from her, saying they would get the disease. "When friends dropped for a visit, she would introduce me, saying, 'She is my son's widow. She has AIDS,'" said Mala. AIDS is now described as "explosive " around the world. A study of a hospital in the port city of Durban in South Africa, where the world's biggest and Africa's second AIDS conference opened last Sunday, found that almost half the beds in medical wards were occupied by AIDS patients. South Africa has one of the world's fastest growing HIV infections, with 1,700 people infected daily, adding to the 4.3 million, or 10 percent of its population, living with HIV. Until now, Asia has been more successful in holding the AIDS virus than Africa, where the disease has killed about 12 million people. AIDS is now threatening to surround many of Asia's poverty-stricken countries. Countries in Asia, such as Cambodia, and Thailand, have HIV infection speeds over 1 percent. But the low speeds hide huge numbers of infected people, because of the population base. In India, for example, 3.7 million are infected, more than in any other country except South Africa. In China, an estimated 860,000 people (the actual number may be a little larger), mainly drug users, live with HIV/AIDS. Gordon Alexander, a senior advisor for UN AIDS in India, estimates that the number hit by AIDS in Asia will climb about eight million over the next five years from about six million. In many Asian countries, the battle against HIV is a social and cultural one against public discussion of sexual health put a nationwide media campaign into action to limit the speed of HIV through unsafe sex. Brenton Wong, an official for Singapore's Action for AIDS, _ . "Shame and deny is still very, very common so people are afraid to get tested and many times won't even tell their families if they test positive," said Wong. It is judged that there are _ people hit by AIDS in Asia or so.

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. Where were the tested students from? They were from _ .

Dogs can know the meaning of a human perspective, say researchers. Dogs are more capable of understanding situations from a human's point of view than has previously been recognized, according to researchers. They found dogs were four times more likely to steal food they had been forbidden, when lights were turned off so humans in the room could not see. This suggested the dogs were able to alter their behavior when they knew their owners' perspective had changed. The study, published in Animal Cognition, conducted tests on eighty-four dogs. The experiments had been trying to find whether dogs could make their behavior suitable to react to the changed circumstances of their human owners. It wanted to see if dogs had a "flexible understanding" that could show they understood the viewpoint of a human. It found that when the lights were turned off, dogs in a room with their human owners were much more likely to disobey and steal forbidden food. The study says it is "unlikely that the dogs simply forgot that the human was in the room" when there was no light. Instead it seems as though the dogs were able to differentiate between when the human was unable or able to see them. Juliane Kaminski carried out the research into how dogs are influenced by human circumstances. Dr Juliane Kaminski, from the University of Portsmouth's psychology department, said the study was "incredible because it implies dogs understand the human can't see them, meaning they might understand the human perspective". Previous studies have suggested that although humans might think that they can recognize different expressions on their dogs' faces, this is often inaccurate and a projection of human emotions. "Humans constantly attribute certain qualities and emotions to other living things. We know that our own dog is clever or sensitive, but that's us thinking, not them," said Dr Kaminski. "These results suggest humans might be right, where dogs are concerned, but we still can't be completely sure if the results mean dogs have a truly flexible understanding of the mind and others' minds. It has always been assumed only humans had this ability. This passage can be classified as _ .

Having Breakfast Or Not Will it matter if you don't take your breakfast? A short time ago, a test was given in the United States. People of different ages, from 12 to 83, were asked to have a test. During the test, these people were given all kinds of breakfast, and sometimes they got no breakfast at all. Scientists wanted to see how well their bodies worked when they had eaten different kinds of breakfast. The results show that if a person eats a right breakfast, he or she will work better than if he or she has no breakfast. If a student has fruit, eggs, bread and milk before going to school, he or she will learn more quickly and listen more carefully in class. The result is opposite to what some people think. Having no breakfast will not help you lose weight . This is because people become so hungry at noon that they eat too much for lunch. They will gain weight instead of losing it. You will lose more weight if you reduce your other meals. During the test, the people were given _ .

Be sure to book a table if the restaurant you choose is an expensive or a popular one. You will feel embarrassed to show up without booking and having to wait for a table, leaving very bad impression on your friend, especially your girl friend. Also, be sure to check to see if you need to be properly dressed and tell your friend ahead of time what to wear. When your food arrives, proper dining manners make you eat at a right pace so that you have time to talk. A good measure of how fast you should eat is to count 10 seconds between each mouthful and it's bad manners if you eat too fast and then spend the rest of the time watching your friend eat. Don't make noise when having soup and chewing, or chew with your mouth open. Your napkin should be placed on your lap at all times. Don't put it in any other place. If you have to get up, place it neatly on your seat. When eating, put your fork straight in your mouth. Don't place your fork in the side of your mouth as it increases the chances of dropping your food, which could be very embarrassing. If you get food stuck in your mouth, don't pick it out with your fingers or fork at the table. Excuse yourself and go to the restroom and get it out with a toothpick. When dining, keep your eyes on your friend at all times and try to smile between mouthfuls. Sometimes, you should make an effort to show some interest and ask questions like, "How do you like the beef?" If she needs, you are the one who is supposed to flag down the waiter by a gentle wave of the hand until someone notices you. Good eating manners do NOT include _ .

Scottish pupils recently were part of a new scheme that allowed them to take their exams online. Those examinations provided a glimpse of the future in May when 120 _ in 10 centers in Scotland sat in front of computers to take a multiple-choice online exam. Although candidates were using a computer mouse instead of a pen, in all other ways the exam was the same as normal. Exam rooms were set out to ensure that only the candidates and the teachers were able to see the individual screens. The online answers were sent directly to a safe area. According to the students at St Ninian's in East Renfrewshire who took an online French exam, it was definitely the most motivated they had ever felt when taking an exam. "I could go as fast as I wanted to, rather than as slow as everyone else wanted to," said one. "It was better than looking back and forth between the questions," said another. One pupil even described it as fun. Their head teacher, Dorothy Graham, was not so surprised, "They are so used to doing things on computers that it seems natural for them. The boys liked it because they didn't have to worry about how neat their work was." The only things that worried her were power cuts and systems' crashing. It's thought that online exams could be the norm in about five years. However, last year there were warnings about computerizing exams in England and Wales. It's thought that it could be unfair to some students if they come from homes without access to a computer. Pupils who take this kind of exam _ .

"Lizzie, there's a letter for you!" Emily called up the stairs to her sister. Elizabeth looked down. "Is it from Harvard? They refused my application once." Emily answered, "No, it's from Yale." Quickly, Elizabeth walked downstairs. She took the letter and opened it. "Rejected again," Elizabeth said unhappily. "Who says women can't be doctors?" "They are fools not to accept you. You can't let them stop you, Lizzie," Emily said. "I won't. I'll apply to Geneva Medical College," Elizabeth told her sister. As it turned out, the professors at Geneva Medical College were not fools. They allowed Elizabeth Blackwell to study medicine. In 1848, a year before Elizabeth would graduate, a typhoid epidemic broke out in New York. Elizabeth wrote to Emily. "There's an outbreak of typhoid, and I am going to help. It is dangerous, so if I should not survive, please do me the honor of studying medicine yourself." Emily replied, "Encouraged by your dream and success, I have decided to study in medical school, as well." Having survived the disease, Elizabeth tried to set up a private medical practice. "I graduated first in my class but no one believes a woman can be a good doctor," she said to Emily one day. "All I hear is that doctors should be men, while women should stay home to cook and clean." Emily said worriedly, "I will graduate in June with my medical degree. What shall we do?" Elizabeth thought for a while and replied, "There's a big house in the poor part of our town. We can practice medicine there for people who couldn't afford care." Soon with the help of some friends, Elizabeth and Emily bought the house and opened a hospital for poor women and children. "We'll have an all-women staff ," Elizabeth said. "And later, we'll add a medical college for women!" Emily added. At last, Elizabeth realized her dream of being a doctor. Hearing Elizabeth's words about the letter from Yale, Emily felt _ .

This might not sound so extraordinary, but I didn't just read a book in print, on an e-reader or even on a mobile phone. Instead, I read a book on dozens of devices . I was not trying to set a Guinness world record. I wanted to answer a question I often hear: which e-reader or tablet is the best for reading books? So I set out to try them all, reading a chapter on each: the Amazon Kindle, the first and second generation Apple iPads and mobile phones. To be fair, I also read a chapter in that old-fashioned form -- an old print paperback. The book I chose was The Alienist. For the first chapter, I turned to an Amazon Kindle. Shopping on Amazon for the Kindle is simple; you go to Amazon's Web site and buy the book, which is then sent to any devices with Kindle software installed . Reading on the Amazon Kindle is a joy in many aspects. The Kindle is light.Its six-inch screen is the perfect size for reading, and reading on its black and white E Ink display doesn't harm your eyes. Battery life is outstanding; on average you charge the device only once a month. My only complaint with the Kindle design is the placement of the keyboard at the bottom of the device. Amazon's CEO has noted during past product announcements that the keyboard is there to help people take notes or search. But to me,it seems like a waste of space. Despite the small screen on a mobile phone, I find reading on one to be simple and satisfactory. All of the mobile phones on which I read chapters felt somewhat similar; although screen brightness and the size of the phone's screen did vary. If I had wanted to, I could have bought my book through dozens of e-book apps in the Apple App Store. Most are free and offer access to thousands of free e-books or paid versions. But the big downside for many is that you can read them only on Apple devices. Both iPads 1&2 offer an immersive reading experience. I found myself jumping back and forth between my book and the Web, looking up old facts and pictures of New York City. I also found myself being sucked into the wormhole of the Internet and a few games of Angry Birds rather than reading my book. For the last chapters of the book, I read the paperback, which is still my favourite choice. Since we are comparing devices so I guess I need to choose one. In the end it might come down to Kindle. But if money is tight, go for print. My used paperback cost only$4 from Amazon. According to the passage, which of the following statements on the Amazon Kindle is NOT TRUE?
|
[
"Its battery can last for a long time.",
"Its keyboard is kept in the proper position.",
"It is easy to carry and the screen size is proper.",

Sometime in the next century, the familiar early-newspaper on the front porch will disappear. And instead of reading your newspaper, it will read to you. You'll get up and turn on the computer newspaper just like switching on the TV An electronic voice will distribute stories about the latest events, guided by a program that selects the type of news you want. You'll even get to choose the kind of voice you want to hear. Want more information on this brief story? A simple touch makes the entire text appear. Save it in your own personal computer if you like. These are among the predictions from communication experts working on the newspapers of the future. Pictured as part of broader home-based media and entertainment systems, computer newspapers will unite print and broadcast reporting, and offer news and analysis with video images of news events. Most of the technology is available now, but convincing more people that they don't need to read a newspaper is the next step. But resistance to computer newspapers may be stronger from within journalism. Since it is such a cultural change, it may be that the present generation of journalists and publishers will have to die off before the next generation realizes that the newspaper industry is no longer a newspaper industry. Technology is making the end of ' traditional newspapers unavoidable. Despite technological advances, it could take decades to replace newsprint with computer screens. It might take 30 t0 40 years to complete the changeover because people need to buy computers and because newspapers have established financial interests in the paper industry. Which of the following is NOT an advantage of computer newspapers?

Many people watched the lift-off of the space shuttle Columbia on March 21, 1982. But none watched more closely than eighteen-year-old Ted, as Ted's insects were on board the shuttle. The Shuttle Student Involvement Program invited students to make a science experiment. The experiment would be done by astronauts on the space shuttle. Ted had always been interested in space and flight. Insect flight especially interested him. Ted noticed that insects need gravity to take off and land. They need gravity to fly in a straight line. But in space, there is no gravity. Could insects fly in zero gravity? That is what Ted wanted to find out. Ted made an experiment called "Insect in Flight Motion Study". He entered his experiment and soon news came that _ . A large team of scientists and engineers helped Ted get his experiment ready to fly. There were many questions to be answered first. What kind of insects would Ted use in his experiment? The insects would have to be strong enough to live on the shuttle for nine days without much food. What kind of container would hold the insects? Would the insects die during the shuttle flight? After months of hard work, the "insectronauts" were chosen. A group of moths, flies, and honeybees were put into a special box and put onto the space shuttle. When Columbia flew into space, it was carrying insect passengers. On March 24, astronauts Gordon Fullerton and Jack Lousma took out the box that held the insects. They began filming the insects with a special video camera. When the space shuttle landed Ted was able to watch the video film of insects. Just as he thought, most of the insects did have trouble flying in zero gravity. The flies did well. But the moths' flight seemed "uncontrolled". They would often just hang in the air. The bees had the most trouble. They couldn't fly at all! The film showed bees spinning around in all directions. Others were just floating about in the box. Ted learned the answer to his question about insects' flight in zero gravity. But he also learned a lot more. He learned about the hard work needed in making a successful experiment. How did Ted learn the answer to his question about insects' flight in zero gravity?

Half a century after the March of Dimes (a US charity organization that collects money for children) put the 20th century's most feared childhood disease on the road to eradication , Bill Gates declared polio his important job and challenged world leaders to finish the job. India, Nigeria, Pakistan and Afghanistan now have active transmission of the disease. Gates says the biggest problem with the success of the Global Polio Eradication program in those countries and elsewhere is lack of money. The Bill and Melinda Gates Foundation plans to increase its $200 million annual contribution by $102 million this year, Gates says. Gates recently met privately with Pakistan's President in Washington, D.C., to try to persuade him to provide full support for Pakistan's eradication plan. Children in the USA also are at risk, experts say. Parents who don't vaccinate their children because they are fearful of vaccine side-effects create a large number of children who are likely to be harmed by the virus. "If you increase the number of unvaccinated children, you increase the chance that this virus will find new subjects," says David Oshinsky, Pulitzer Prized-winning author of Polio: An American Story. "We've got to get this vaccine into the mouths of children," says Bruce Aylward, head of the World Health Organization's eradication program. In 1988, when the World Health Organization launched the Global Polio Eradication program, the disease killed 350,000 children a year worldwide. By last year, the total dropped to fewer than 1,500 worldwide, Aylward says. If Gates provides the final push for polio eradication, he may be remembered as much for helping prevent polio as for founding Microsoft, Oshinsky says. "As long as there's polio anywhere, people everywhere are at risk," Aylawrd says. " According to the passage, which of the following about Bill Gates is TRUE?
|
[
"He is the founder of the Global polio Eradication program.",
"He persuades some of the world leaders to support the eradication plan.",
"His foundation contributes $302, 000 to eradicate polio every year.",

When a caterpillar feeds on a tomato leaf , the plant moves rapidly to meet with a defensive response , systematically releasing " proteinase inhibitors " -- proteins that interfere with the caterpillar's digestion -- throughout the plant , especially in the leaves . But how does the message get from the wounded leaf to the rest of the plant ? Most scientists believed the alarm was spread by chemical messengers until a team of researchers headed by David Weldon-- a biologist at the University of East Anglia in Norwich , England -- made a shocking discovery . An injured leaf , the researchers found , sends an electrical signal to warn neighboring leaves of upcoming danger . It's a " terribly tiny current " driven by an electrical potential difference of only 20 millvolts , says Weldon , who measured the voltage after electrodes were attached to the plant's surface . " Right now , all we can say is that there is a correlation , " Weldon notes . " If you wound the plant , you'll see an electrical signal accompanied by a biochemical response . " To learn more about the reaction , Weldon's team plans to insert electrodes within the pant tissue ( rather than on the surface ) to determine what's going on at the cellular level . The findings may help explain other mysteries surrounding plants . For example , many plants start to flower in springtime , as days grow longer , but plants sense the change in the day length through their leaves , while flowers begin to bloom at the buds . " There must be a signal from the leaf to the growing points , " Weldon says . " So far , no one has come up with a convincing chemical mechanism . Maybe an electrical signal is involved . " What is the function of the " proteinase inhibitors " in tomato plants ?

The moon looks bigger than the stars at night. But in fact, it is smaller than any of them. The moon looks big to us, because it is closer to us than any star. The moon goes around the earth. It makes one trip about four weeks. The moon is a round ball and looks beautiful. Don't you think so? Now people know quite a lot about the moon. There is no air or water on the moon so there are not any trees or animals, or people on the moon. The moon gets its light from the sun, but some places on the moon are quite dark. Then days on the moon get hotter than boiling water. The nights get colder than the North Pole on the earth. The sun _ to the moon.

Tang Zhou and his wife are planning to have their second child, a test-tube baby. His wife had a natural delivery when she was 34 and their first child, a boy, is now 7. The couple are now hoping to have a daughter through _ in the US. "My wife couldn't bear another delivery because of her heart condition and her age. Surrogacy helps avoid the risks to older mothers," Tang said, "Moreover, our second child will be born in the US and become a citizen there. That is not a bad choice." The couple spent weeks researching their move, looking for a reliable agency that provides surrogacy services overseas. Surrogacy is still illegal in many countries, including China. "We will be taking much higher risks by relying on a surrogate mother in China because we are not protected by any regulation or law. You pay a lot of money but may meet with many problems," Tang said. "You might not even get your baby back." Tang and his wife are part of an increasing number of Chinese couples who are turning to surrogacy services. Tang also considered surrogacy in Thailand but dropped the idea after recent reports about a baby with Down Syndrome who was delivered through surrogacy and said to have been deserted in Thailand by the biological parents from Australia. Instead, Tang chose the California Surrogacy Center agency as his first option after reading the detailed introduction on its website. Compared with many other agencies that he could contact only via e-mail, the center has a consulting office in Beijing, Tang said. The center is in San Diego, California, and has satellite offices in Los Angeles and Beijing. According to Liu, the center has been operating for more than eight years, and about 100 surrogate mothers live in California. A surrogate mother refers to a mother who _ .

Women are friendly. But men are more competitive. Why? Researchers have found it's all down to the hormone oxytocin . Although known as the love hormone, it affects the sexes differently. "Women tend to be social in their behavior. They often share with others. But men tend to be competitive. They are trying to improve their social status," said Professor Ryan. Generally, people believe that the hormone exytocin is let out in our body in various social situations and our body creates a large amount of it during positive social interaction such as falling in love or giving birth. But in a previous experiment Professor Ryan found that the hormone is also let out in our body during negative social interactions such as envy. Further researches showed that in men the hormone oxytocin improves the ability to recognize competitive relationships, but in women it raises the ability to recognize friendship. Professor Ryan's recent experiment used 62 men and women aged 20 to 37. Half of the participants received oxytocin. The other half received placebo . [( )] [( :Love my Dog.)] After a week, the two groups switched with participants. They went through the same procedure with the other material. Following each treatment, they were shown some video pictures with different social interactions. Then they were asked to analyze the relationships by answering some questions. The questions were about telling friendship from competition. And their answers should be based on gestures, body language and facial expressions. The results indicated that, after treatment with oxytocin, men's ability to correctly recognize competitive relationships improved, but in women it was the ability to correctly recognize friendship that got better. Professor Ryan thus concluded: "Our experiment proves that the hormone oxytocin can raise people's abilities to better distinguish different social interactions. And the behavior differences between men and women are caused by biological factor that are mainly hormonal." What can we learn from Professor Ryan's previous experiment?

Put a little love in your life I remember growing up, my mom always said, "Half the fun of doing anything is sharing it with others." It is so true. Friends and mates allow us to enjoy our success and our joys, comfort us in our challenging moments, and provide a mirror for us to learn more about ourselves. I've always looked at friends as the family we choose. They enrich our lives. As Robert Louis Steven once said, "A friend is a present which you give yourself." To be a good friend or partner, it's importable be a good listener. Hear what your friend or mate has to say first rather than jumping to conclusions or getting defensive. Sometimes it is useful to be their mirror, for when they hear their words repeated back to them, it can help them to realize that what they said was not exactly what they meant to say. Patience, compassion and empathy are also important traits in being a good friend or partner. You know the old golden rule, "Care for others the way you would like them to care for you." The support of a friend during a tough time could make the difference between success and failure. Encouragement and confidence are priceless gifts that can help change a person's life. Take care, though, with whom you choose to have close relationship, for they can have a tremendous impact on your self-esteem and life path. As someone once told me,"the attitude of your friends are like the buttons on an elevator. They will either take you up or down." In order to make good friends, you should do the following except

If you remember taking class notes in longhand , there's a good chance you also remember more about a variety of topics than today's students do. A study investigated whether taking notes by hand helps you learn better than taking notes on a laptop. It was no contest. Study authors and psychologists Pam A. Mueller of Princeton University and Daniel M. Oppenheimer of the University of California- Los Angeles conducted three separate experiments involving a total of 327 students. All students got the same lectures, but some used laptops, and others took notes by hand. When it came to learning the concepts, the handwriters won. When it came to retrieving facts, the groups were comparable, except when given time to go home and look at their notes, at which point the handwriters did better. "Even when allowed to reviewnotes after a week's delay, participants who had taken notes with laptops performed worse on tests of both factual content and conceptual understanding," the study states. Learning suffered not because of "multitasking" or the distraction available to students using Wi-Fi- enabled laptops. In the lab, scientists allowed no extraneous activity. Students who paid attention and took deep notes on their laptop still didn't learn as well--in fact, the study suggests the thoroughness of their notes contributes to the problem. Laptop users tend to record long, _ quotes, which they type mindlessly. Handwriters are more selective. They "wrote significantly fewer words than those who typed," according to the study. By processing and selecting the more important information, they studied more efficiently, said researchers. Here's what's a bit frightening: When the laptop students were instructed to cut down or eliminate the verbatim note taking, they couldn't. The study adds to a ton of evidence that for learning, writing is better and that the hand has a "unique relationship with the brain when it comes to composing thoughts and ideas." Of course, the chance of persuading students to put away their laptops is probably zero. Many of them can't write longhand, a forgotten subject in many American schools, itself a source of controversy. So are we stuck with traditional classrooms and learning techniques if we want the brightest pupils? Perhaps not: Another possibility, some have suggested, is apps that permit handwriting on tablets, a compromise that students might accept. What can be inferred from the passage?

Certain animals know without analysis the difference between a number of objects and a smaller number. In his book The Natural History of Selbourne (1786), the naturalist Gilbert White tells how he _ removed one egg a day from a kind of bird Plover's nest, and how the mother laid another egg each day to make up for the missing one. He notes that other kinds of birds ignore the loss of a single egg, but if more than one egg has been removed, they will give up their nests. It has also been noted that a certain type of bees always provides five--never four, never six--caterpillars for each of their eggs so that their young have something to eat when the eggs have hatched out. Research has also shown that both mice and pigeons can be taught to distinguish between odd and even numbers of food pieces. These have led some people to think that creatures can actually count. They also point to dogs that have been taught to respond to questions about numbers with the correct number of barks. Animals respond to quantities only when they are connected to survive as in the case of the eggs, or survive as in the case of food. They can "count" only when the objects are present and only when the numbers involved are small--no more than seven or eight. In lab experiments, animals which are trained to count one kind of objects were unable to count any other type. What interests them are the objects, not the numbers. Animals' achievements simply are not equal to evidence of counting. They only show the results of clever, careful training. The author mentions all of the following are aware of quantities in some way EXCEPT _ .

University of Maryland student Ben Simon and his friends couldn't stand to see good food thrown out on their campus."We basically noticed that some of the extra food from the dining hall was going to waste at the end of the day.And we met with the dining services and asked them whether it would be okay if instead of throwing out the food we would donate it.And they were on board," he said. So 18 months ago,the students began what they call the Food Recovery Network.Each night,volunteers would show up at a campus dining hall to pick up leftovers and deliver them to area shelters and food banks.So far,they have donated more than 23 000 kilos of food that would otherwise have been thrown out. Nationwide,$165 billion worth of food is wasted each year,according to the National Resources Defense Council.Spokesman Bob Keefe says that is about 40% of the country's entire food production."If we can reduce our waste in this country by 15%,we can feed 25 million hungry Americans.That is a huge benefit.That is what programs like this Food Recovery Network are doing," he said. Christian Life Center is one of the beneficiaries of the students' efforts.Ben Slye,the senior pastor ,said,"It has been just amazing to see these students take their own time,their own vehicles and own gas money and be able to make an effort like this.Each week we are able with this food probably to feed over hundred people." The University of Maryland's Food Recovery Network now has 200 volunteers and the program has expanded to 18 schools across the country."I want to grow 18 chapters to a thousand chapters within five years.And once we get to the Food Recovery Nation being at every college campus in America,we want to expand to restaurants and farms." said Simon. The volunteers are committed to making that happen. The dining services in University of Maryland _ .

Oxford University students think about the collegiate system as follws: *"The collegiate system is exactly what I expect, lots of students all living together, with the JCR(Junior Common Room) acting to support students and organize parties and social events." 2nd year undergraduate, Archaeology and Anthropology *"Most of all, I like the collegiate structure, which appeals to me as it is less of an imposing 'body' to get involved with. This allows you to play sports and do other things similarly at any level that you like. I play football and cricket for my college and also play recreational rugby and tennis where I can fit it in." 2nd year undergraduate, Biochemistry *"I choose to study at Oxford firstly because I want to study at the highest level and stretch my mind;I felt that the Oxford tutorial system is the best environment to achieve this. Secondly because the collegiate system seems to offer a friendlier atmosphere than a large campus..." 2nd year undergraduate, Mathematics *"Not only is Oxford one of the top universities in the world...students here have the benefit of the social support of a small college community." 3rd year undergraduate, Medicine *"The aspect of Oxford that I appreciate the most is the sense of belonging that the collegiate system offers. If you choose to accept it, your college will provide you with the social scaffolding to ensure that both your weeks and weekends are fun.." DPhil student, Inorganic Chemistry *"The college system and the amazing sports opportunities make the experience of Oxford even better because there is so much more to do once you leave the lab..."

A new study suggests that early exposure to germs strengthens the immune system. That means letting children get a little dirty might be good for their health later in life. The study involved laboratory mice. It found that adult mice raised in a germ-free environment were more likely to develop allergies, asthma and other autoimmune disorders. There are more than eighty disorders where cells that normally defend the body instead attack tissues and organs. Richard Blumberg,who led the study,is a professor at Harvard Medical School in Boston,Massachusetts. He says,in 1989,medical researchers who sought to explain these diseases, first discovered that the increasing use of antibacterial soaps and other products, especially early in life, could weaken immune systems. Now, Dr. Blumberg and his team have what is the first biological evidence to link early exposure to germs to stronger adult immune systems. They say this exposure could prevent the development of some autoimmune diseases. In the adult germ-free mice, they found that inflammation in the lungs and colon was caused by so-called killer T cells. These normally fight infection. But they became overactive and targeted healthy tissue--an autoimmune condition seen in asthma and a disease called ulcerative colitis . Dr. Blumberg says the mice raised in a normal environment did not have the same reaction. He says their immune systems had been "educated" by early exposure to germs. Rates of autoimmune disorders are rising worldwide, but mostly in wealthier, industrialized countries. According to Dr. Blumberg, it might be high time that people were warned to be more careful with the early use of antibiotics and the prescription from their doctors. Rob Dunn is a professor of ecology and evolutionary biology at North Carolina State University in Raleigh. He says the new study does not mean people should stop washing. "Wash your hands , but don't do it with antibacterial soap. Let your kids play in a reasonable amount of dirt and get outside and get exposed to a diversity of things", says Rob Dunn. Who first found immune systems might get harmed by overly using antibacterial products?

In meditation ,people sit quietly and focus their attention on their breath .As they breathe in and out ,they attend to their feelings .As thoughts go through their minds. They let _ go. Breathe .Let go .Breathe .Let go . According to a recent study at the Insight Meditation Society in Barre,Massachusetts. Three months of training in this kind of meditation causes a market change in how the brain allocates attention. It appears that the ability to let go thoughts that come into mind frees the brain to attend to more rapidly changing things and events in the outside world. Expert mediators are better than other people at catching such fast-changing stimuli( ),like facial expressions. The study provides evidence for changes in the workings of the brain with mental training. People can learn and improve abilities of all sorts with practice, everything from driving to playing the piano. The study has shown that meditation is good for the brain. It appears to reduce pressure and promote a sense of well-being. In an experiment, 17 volunteers with no meditation experience in the experimental group spent three months meditating 10 to 12 hours a day .A control group also with no meditation experience meditated for 20 minutes a day over the same period .Both groups were then given the tests with two numbers in a group of letters. As both group looked for the numbers , their brain activity was recorded. Everyone could catch the first number .But the brain recordings showed that the less experienced mediators tended to grasp the first number and hang onto it, so they missed the second number .Those with more experience gave less attention to the first number .as if letting it go ,which led to an increased ability to grasp the second number ,This shows that attention can change with practice. Just ask Daniel Levision , who meditated for three months as part of the study ."I am a much better listener," he said . " I do not get lost in my own personal reaction to what people are saying." Meditations manage their daily tasks better because they _ .

The space shuttle Discovery has had a long and busy career. For 27 years, it has worked for NASA, carrying astronauts to space and back on 39 missions. On March 9, 2011, after returning from its final voyage, the world's most traveled spaceship was retired. A crowd of shuttle workers, reporters and schoolchildren waited to greet Discovery at Kennedy Space Center in Cape Canaveral, Florida. Three minutes before noon, they watched as the shuttle appeared in the sky and made one last touchdown. "For the final time: wheels stop," Discovery's commander Steven Lindsey said when the shuttle rolled to a stop. Discovery's final trip was to the International Space Station (ISS), a giant space lab in the sky. Discovery's crew took care of the last U.S. construction project at ISS. They delivered 10 tons of supplies for the ISS. The six-person crew also dropped off an unusual companion for ISS's researchers: a human-like robot named Robonaut 2. Astronauts will assemble R2 at the ISS over several months. Now, NASA is its shuttle programme. NASA is to begin work on new spaceships that can travel longer distances. Discovery's retirement is the first of three. Endeavor, another shuttle, is scheduled to make its final voyage soon. And Atlantis's last trip is planned for the end of June. Museums across the country have requested the retired shuttles. The Smithsonian's Air and Space Museum, in Washington, D.C., was the lucky recipient of Discovery. The museum's collection contains hundreds of NASA artifacts. Where will the other shuttles go? You'll have to wait to find out. NASA will announce its decision on April 12, the 30 anniversary of the first space shuttle launching. Stay tuned! As part of the final mission, Discovery's crew _ .
