In many European countries it is normal to have a long break in the middle of the day when all members of the family return to their houses to eat together. This is not very common in Britain because normally it is a long way from the place of work or school to the home. Consequently the British people tend to have a big breakfast before they go to work and the meal at midday is not spent with the members of the family but with workmates or schoolmates. Lunch is normally eaten between 12: 30 p.m. and 1: 30 p.m. Most people finish work at five thirty. It often takes at least an hour to get home from the school or workplace so people tend to eat their evening meal or "dinner" between 6: 30 p.m. and 8 p.m. On Sundays people don't have to work, so they take the opportunity to eat together with their family. Sunday lunch is usually the best meal of the week and many of the meals which are considered typically British are eaten for Sunday lunch. For example roast beef and Yorkshire pudding. This is a typical British family eating together on Sunday. After lunch the father will smoke his pipe and read the newspaper sitting on his favorite armchair while his wife washes the dishes. The children will play traditional English games such as hopscotch, skipping or doctors and nurses. Although everyone in Britain understands that "breakfast" is the first meal of the day, there is a lot of confusion about the words for other meals such as "dinner, lunch, tea, high tea, brunch and supper" and if you ask a British person what these words mean, most of them will give you a different answer according to what part of the country they are from or what social class they are from. Another example of this is the pronunciation of the word "scones" (a type of cake eaten with Devonshire clotted cream, strawberry jam and cups of tea, known as a "cream tea") During the workday, the Europeans eat lunch together with the family while the British eat _ .

Sometimes, you feel down or unhappy and it is hard to come back to your high spirit. So if you're having a bad day and need a boost,then help is just a click away. A website is trying to offer people positive messages from strangers to cheer them up. It announces to be"the nicest place on the Internet",where happy people can present their positive thoughts and feelings to those who are in low spirits. The website, thenicestplaceontheinter.net, lets people post videos of themselves blowing kisses and leaving positive and encouraging messages to lift visitors' spirits. The website was created by Jeff Lam and is considered to help many people out when they feel low. The well-known artist who lives in San Francisco said he came up with the idea when he and his friend Lauren were having one of those bad days. "We tried to become cheerful,but none of the usual methods seemed to be working. Not music. Not food. What we hoped was something positive, honest and good.So with only a camera and work-free weekend, we created'The Nicest Place On The Internet," he explained on his website. One user of the site, Joseph Meehan, 27, from Birmingham, said,"it's a fun and exciting website. I visit every once in a while when I'm missing my friends or family. I think it could really be a help to people that are feeling down or sad. It may even stop them from doing something stupid. You can also post your video to the website, and they add it to the series. It's very easy to share the love." Mr. Lam is now working on a new project that allows people to leave positive voicemails for strangers. The idea is that strangers send an audio diary by leaving a voicemail and then anyone can listen to it. The website was created in order to _

It seems that politicians around the world are thinking about the health of their countries. While in China, Chen Zhu has announced his plans for a universal health service and reform across health services. Gordon Brown, the UK Prime Minister, has also announced he is planning to make some changes in our health service. The crux of Mr. Brown's proposals are related to giving the NHS (National Health Service) a greater focus on prevention, rather than just curing patients. He is planning to introduce increased screening for common diseases such as heart disease, strokes, and cancer, for example, breast cancer. In Britain there are 200,000 deaths a year from heart attacks and strokes, many of which might have been avoided if the condition had been known about. Initially, the diagnostic tests will be available for those who are vulnerable, or most likely to have the disease. One example is a plan to offer all men over 65 an ultrasound test to check for problems with the main artery , a condition which kills 3,000 men a year. The opposition have criticized Mr. Brown's proposals, saying that they are just a trick, and claiming that there is no proper timetable for the changes. They also say that Mr. Brown is reducing the money available for the treatment of certain conditions while putting more money towards testing for them. The NHS was founded in 1948, and is paid for by taxation. The idea is that the rich pay more towards the health service than the poor. However in recent years there has been a great increase in the use of private healthcare, because it's much quicker. NHS waiting lists for operations can be very long, so many people who can afford it choose to pay for medical care themselves. According to the passage, the purpose of the health reform plan in the UK is to _
[ "encourage more private healthcare.", "focus on the prevention rather than on curing the patient.", "deal with the main artery problems.", "fight against the opposition in the UK." ]

Alzheimer's disease is a major national health problem. Nearly 2 million Americans over the age of 65 have Alzheimer's disease. It is a leading cause of death among the elderly. But Alzheimer's disease is not confined to the aged. There may be a million or more people under the age of 65 suffering from the disease. At one time, people suffering from the disease were said to be "getting old". The disease was thought to be a natural part of growing old, but it is now known that Alzheimer's disease strikes young and old alike. It is an organic disease that destroys brain cells. Alzheimer's disease affects the patient's memory, speech, and movement. In the beginning stages of the disease, the patient may seem slightly confused. He may have trouble speaking, then the patient's memory begins to fail. He may forget dates, numbers, names and plans. As the disease progresses, the patient may not recognize family and friends. These symptoms often cause terrible anxiety in the patient. He may feel lost and frightened. Sometimes the patient reacts with wild and bad behavior. In the last stages of the disease, the patient may not be able to take care of himself. He may have lost the ability to speak and walk. Scientists don't know exactly what causes Alzheimer's disease. It may be caused by a virus .It may be caused by a poisonous substance in the environment. At present, there is no cure for the disease. But there are ways to slow its progress. Exercise and physical treatment can help the patients of this disease. All of the following are symptoms of Alzheimer's disease EXCEPT _ .

Some scientists have suggested that it might in some cases be ethically acceptable to clone existing people. One possibility is generating replacement for a dying . All such possibilities, however, raise the concern that the clone would be treated as less than a complete individual, because he or she would likely suffer from limitations and expectations based on the family's knowledge of the genetic "twin." Those expectations might be false, because human personality is only partly determined by genes. The clone of an extrovert could have a quite different way of behavior. Clones of athletes, movie stars, or scientists might well choose different careers because of chance events in early life. Some people have also put forward the belief that couples in which one member is infertile might choose to make a copy of one or the other partner. But society ought to be concerned that a couple might not treat naturally a child who is a copy of just one of them. Because other methods are available for the treatment of all known types of infertility, the traditional choice seems more appropriate. None of the suggested uses of cloning for making copies of existing people is ethically acceptable to my way of thinking, because they are not in the interests of the resulting child. It should go without saying that I am strongly opposed to allowing cloned human embryos to develop so that they can be tissue donors. In spite of this, it seems clear that cloning from cultured cells will offer important medical opportunities. Predictions about new technologies are often wrong: societal attitudes change; unexpected developments occur. Time will tell. But biomedical researchers looking into the potential of cloning now have plenty to do. It can be inferred from the text that a clone will _ .

Genzeb Tibeb is very bright. At only 11 years old, her future is looking promising. She is ranked 2nd Out of 56 students at her govemment school in Addis Ababa, Ethiopia where she has been seleeted for a special program because of her talent. She knows she is special and proudly shows off her certificate and book signifying her accomplishments in this special program. But her future hasn't always looked so bright. While her mother, Bekelech, sacrificed immensely for Genzeb, she would not have been able to continue sending her to school. When her husband died, Bekelech was the sole provider for their five children. In order for them to survive, she began the daily routine of walking approximately 8-10 miles a day collecting sticks to sell near her 8' x 10' home in Kichene. It wouldn't have been long before Genzeb would have been, forced to quit school in order to help her mom. But Bright Future changed all that. Genzeb has been at Bright Future for 3 years. Since Ethiopian schools let out early, Genzeb walks to the facility right after lunch. Because of her high ability, she even helps teach the younger children there, building confidence and locking in important foundational academic skills. There's also other meaningful opportunities Genzeb experiences which allow her eyes to be opened to the different opportunities that are available to her if she completes her studies. Field trips are one of her most favorite activities of all. She especially loved the one to Addis Ababa University. She knows it goes beyond fun trips, though. "I am happy because I get extra help for school from Bright Future," Genzeb shares. At so many levels, her involvement with Bright Future allows her to receive a better education, which she values. For one day she wants to help people in need by becoming a doctor. And now she knows, that with a lot of hard work, that dream might just become a reality. From the text we can leam _ .

Gateway Academy Pre-Sessional Courses Our pre-sessional courses are ideal for students who have a conditional place at a British university, but who need to achieve a certain level of English in order to be accepted. The course aims to provide students with the English language and study skills that they need in order to be successful at university or another academic establishment. It is important to note that completion of the course does not guarantee students' entrance into a university. It is necessary for students to show during the course that they have understood the information and skills that they have been taught, and can apply them to their work. Pre-sessional students at Gateway Academy will benefit from: * Small class sizes (no more than 10 students per class) * Twenty three hours of tuition per week * Individual support and tutorials * Regular guest lecturers * The use of the Academy's study and recreational facilities, including the Language Library, the computer suite, and the academy's sports facilities. * A varied social programme including evening entertainments and weekend excursions to popular tourist attractions and cities such as Stonehenge, Oxford and Stratford-on-Avon. The course offers an all-around approach to learning, and covers reading, writing, speaking and listening skills. During the course, students will receive instruction on important techniques such as summary-writing, analysing essay titles, organising writing, note-taking in lectures, giving seminars and making presentations. Students will gain experience in working both individually and in groups. As part of the course, all students will work towards a 5000-word project in their own field of study. Students will receive guidance from their tutors on how best to conduct research and write it up effectively. Students will also work towards a presentation on the same subject. There is no final examination. The attendance, successful completion of assignments and participation in class will be taken into account. Students will be given a full report on their progress at the end of the course. Students need to be aware that the course involves a great deal of coursework, which will require students to manage their time effectively. The passage is written in order to _ .

Cell phones: is there a cancer link? Could your cell phone give you cancer? Whether it could or not, some people are worrying about the possibility that phones, power lines and Wi-Fi could be responsible for a range of illnesses, from rashes to brain tumors. Some say there is evidence to support the growing anxieties. David Carpenter, a professor of environmental health sciences at the university at Albany, in New York, thinks there's a greater than 95 percent chance that power lines can cause childhood leukemia . Also there's a greater than 90 percent chance that cell phones can cause brain tumors. "It's apparent now that there's a real risk, " said Carpenter. But others believe these concerns are unjustified. Dr Martha Linet, the head of radiation epidemiology at the US National Cancer Institute, has looked at the same research as Carpenter but has reached a different conclusion. "I don't support warning labels for cell phones, " said Linet. "We don't have the evidence that there's much danger. " Studies so far suggest a weak connection between EMFs and illness-- so weak that it might not exist at all. A multinational investigation of cell phones and brain cancer, in 13 countries outside the US, has been underway for several years. It's funded in part by the European Union, in part by a cell phone industry group. The final report should come out later this year, but data so far don't suggest a strong link between cell phone use and cancer risk. By saying "I don't support warning labels for cell phones, " Dr Martha Linet has the idea that _ .

The National Geographic Channel has unearthed a time capsule buried by late Apple chairman and co-founder Steve Jobs thirty years ago. The time capsule was buried in Aspen .Colorado .in 1983, shortly after Jobs attended the International Design Conference being held in that city. Organizers called the device the Aspen Time Tube and contributed items like Rubik's cubes and some iconic music. Jobs added his own items to the capsule ,including the " Lisa" ( also known as an "Apple" )"mouse he used for his presentation at the conference. ' Younger readers may not recognize the name but the Lisa Apple mouse was one of the first commercial mice released to consumers. The mouse was specially designed for the Apple Lisa computer. It's also the first personal computer to offer users a graphical user interface Initially ,the plan was to dig up the time capsule in the year2000,but organizers forgot its exact location. Recently .they brought in researchers working with the National Geographic Channel show Diggers to find the device. Eventually they came across the 13-foot-long.1. 5-foot-diameter tube. inside they found a lot of 1980s artifacts that are still being catalogued. "When the end came off .literally things just poured out ."noted Diggers host Tim Saylor "There must be literally thousands of things in there." "They had the foresight to put a bunch of stuff in plastic bags." Saylor said ."I could see at least a dozen plastic bags and other items. But I know for sure there got to be photographs in there. People had hand-written things on the back of the photographs ,so there will be some really interesting things inside." Among the artifacts researchers expect to discover inside :a Steve Jobs speech in which the Apple visionary outlines his predictions for future technologies. We should know more about the researchers ,discoveries once the Diggers program airs this fall. The best title for the passage might be _ .

Monitoring the mood of a pet dog could be used as an early warning sign that an elderly owner is struggling to cope, a new report has claimed. Researchers placed movement sensors on dogs to track their behaviour and identified 17 distinct activities, including chewing, barking, sitting and digging. This allowed them to map the normal behaviour of a healthy, happy dog, which means any changes can be monitored and could indicate an issue with their owner. Nils Hammerla, part of the team from Newcastle University, said, "Humans and dogs have lived together in close relationships for thousands of years, which has led to strong emotional and social mutual bonds." "A dog's physical and emotional dependence on their owner means that their well-being is likely to reflect that of their owner. Any changes such as the dog being walked less often, perhaps not being fed regularly, or simply demonstrating "unhappy" behaviour could be an early indicator for families that an older relative needs help. This is the first system of its kind which allows us to remotely monitor a dog's behaviour in its natural setting." The team of academics, who presented their findings at the 2013 UbiComp conference in Zurich, created a hi-tech, waterproof dog collar for the study. Dr Cas Ladha, who led the study, said: "A lot of our research is focused on developing intelligent systems that can help older people to live independently for longer. But developing a system that _ family and carers that an older relative is well without intruding on the individual's privacy is difficult. This is just the first step but the idea behind this research is that it would allow us to support people without the need for cameras." A range of dogs was used for the study, as the team needed to map distinct behaviours that correlated between different breeds. Which of the following is an advantage of the intelligent system mentioned in the text?
[ "It can indicate that people aren't well.", "It can identify different activities of dogs.", "It monitors an elderly owner without disturbing his privacy.", "It lets people see the dog's behavior clearly." ]

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

Steve Sparks was a young successful lawyer when a bruise on one of the legs of his 3-year-old daughter changed his life. The bruise led to a doctor's visit. The doctor said his daughter was suffering from leukemia . Steve said that in a moment his life changed from what restaurant he was going to take his clients to lunch to whether his daughter Katie was ever going to see her fourth birthday. For three years Katie received a lot of treatment at the Nemours Hospital for Children in Wilmington, Delaware and with the help of wonderful doctors, kind nurses, whom Steve and his wife Michelle called heroes, Katie's leukemia was cured . Forever changed by the experience and encouraged by the heroes at Nemours who saved his daughter's life, Steve felt he couldn't go back to business as usual. He felt there was something else he was meant to do and that something else led him to join the Nemours Foundation at the age of 28. The job change came with a 65% pay cut from what he was making as a lawyer, but Steve thought he was right and it was more important to help those who need help. Steve is glad to have made such a choice. Katie is now a healthy 20-year-old college student and Steve is one of the leaders of the Nemours Foundation. In three weeks Steve will have a party for Katie's 21st birthday, and give big thanks to the Nemours by riding his bicycle from Nemours in Jack-sonville, Florida to Wilmington, Delaware. He'll ride 900 miles in 9 days and raise $100,000 for the Nemours Foundation with the hope of saving more children's lives.

Teenagers who drink alcohol are at higher risk of becoming victims of violence, a Cardiff University study has found. A team from the School of Dentistry's Violence Research Group studied drinking habits in children aged 11 - 16 in England. They found not only a link between drink and violence but also that children who drank were more likely to be hit, even if they weren't violent themselves. The researchers are now calling for measures to prevent alcohol misuse to reduce injury risk. Current policy focuses on reducing aggression but this research shows that there should be equal effort to reduce victimization. More than 4,000 children were surveyed at 13 schools at four local authorities in the North, the Midlands, London, and the South. The study found that 25% of 11-year-olds were drinking monthly and 3.6% daily, with 12.8% admitting to getting drunk 3 to 5 times a year. By the age of 16, 40% were drinking weekly and 6.2% were drinking every day. The research also showed 22.6% of 16-year-olds were getting drunk more than 21 times a year. The study, which has just been published in the Journal of Adolescence, found a strong link between frequency of drinking and frequency of hitting other people. However, children who reported drinking monthly were also three times more likely to be hit. Adolescents who drank but didn't get into fights were more likely to be hit than those who did fight. Professor Jonathan Shepherd, who led the research, said a lot of previous alcohol-related violence work had focused on the offenders rather than the victims. His team is calling for more prevention work from parents and teachers in the first two years of secondary school by taking advantage of the "teachable moment", that is, immediately after a student has missed school because of drunkenness. Previous work by Professor Jonathan Shepherd has shown drinkers may be more at risk of violence because of reduced physical co-ordination, poor decision-making in threatening situations and isolation while out late at night. He said, "This new study seems to be the first to show a direct link between alcohol misuse and victimization. There now needs to be much more effort put into reducing alcohol misuse in order to reduce injury." The main idea of the passage is that teenagers who drink alcohol _ .

Sharks are among the oldest animals on Earth. There are hundreds of kinds of sharks. Most are about two meters long. The dogfish shark, however, is less than twenty centimeters in length. A shark has an extremely good sense of smell. It can find small amounts of matters in water, such as blood, body liquids and chemicals produced by animals. These powerful senses help sharks find their food. Sharks eat fish, other sharks, and plants that live in the ocean. Sharks grow slowly. About forty percent of all sharks lay eggs. The others give birth to live young. Some sharks carry their young inside their bodies as humans do. Some sharks are not able to reproduce until they are twenty years old. Most reproduce only every two years. And they give birth to fewer than ten young sharks. For this reason, over-fishing of sharks is of special danger to the future of the animal. Sharks are important for the world's oceans. They eat injured and diseased fish. Their hunting activities mean that the numbers of other fish in ocean waters do not become too large. This protects the plants and other forms of life that exist in the oceans. People hunt sharks for sport, food, medicine and their skin. Experts say the international market for some kinds of sharks has increased because many parts of a shark are valuable.Collectors pay thousands of dollars for the jaws of a shark. Shark liver oil is a popular source of Vitamin A. The skin of a shark can be used like leather. In Asia, people enjoy a kind of soup made from shark fins. Experts say a fisherman can earn a lot of money for even one kilogram of shark fins. Sharks are among the oldest animals on Earth, but some sharks are in danger of disappearing from Earth. If too many sharks in one area are killed, that group of sharks may never return to normal population levels. Sharks eat other fish, _ .

Who are the elders in your family? The most common answer is that they are your parents, grandparents, uncles, aunts, and elder cousins ------in a word, any who is older than you. But that doesn't really answer the question, does it? In a normal family, there is a big difference between being elderly and being an elder. Elders are the storytellers, the cooks, the historians, the authorities, the knitters, and the workhorses. They are the people we respect and turn to for answers or help when we are in trouble, because of their many years of life experience. Most of all, they are the people who raised you and your loved ones and helped you growing into the people you are. For many years, they carried the burden of caring for your family and leading it to better times. Now it's your turn to dote on them. Ensuring the welfare of your elders should come as naturally to us as raising our children. Unfortunately, too many people take their parents' and grandparents' ability to care for them for granted. And in a country where so many of us live hundreds of miles from our families, looking after loved ones can be difficult. Even so, you should make sure your loved ones are taken care of no matter where they live, and try to look after the seniors living alone in your neighbor, too. Taking responsibility for the elders in our society in an important thing that all citizens should do. Which of the following opinions doesn't the author agree with?

Unlike chemists and physicists, who usually do their experiments using machines, biologists and medical researchers have to use living things like rats. But there are three Nobel prize-winning scientists who actually chose to experiment on themselves - all in the name of science, reported The Telegraph. 1. Werner Forssmann (Nobel prize winner in 1956) Forssmann was a German scientist. He studied how to put a pipe inside the heart to measure the pressure inside and decide whether a patient needs surgery. Experiments had been done on horses before, so he wanted to try with human patients. But it was not permitted because the experiment was considered too dangerous. Not giving up, Forssmann decided to experiment on himself. He anaesthetized his own arm and made a cut, putting the pipe 30 centimeters into his vein. He then climbed two floors to the X-ray room before pushing the pipe all the way into his heart. 2. Barry Marshall (Nobel prize winner in 2005) Most doctors in the mid-20th century believed that _ was down to stress, spicy food or an unusually large amount of stomach acid. But in 1979 an Australian scientist named Robin Warren found that the disease might be related to a bacteria called Helicobacter pylori. So he teamed up with his colleague, Barry Marshall, to continue the study. When their request to experiment on patients was denied, Marshall bravely drank some of the bacteria. Five days later, he lost his appetite and soon was vomiting each morning - he indeed had gastritis. 3. Ralph Steinman (Nobel prize winner in 2011) This Canadian scientist discovered a new type of immune system cell called the dendritic cell. He believed that it had the ability to fight against cancer. Steinman knew he couldn't yet use his method to treat patients. So in 2007, when doctors told him that he had cancer and that it was unlikely for him to live longer than a year, he saw an opportunity. With the help of his colleagues, he gave himself three different vaccines based on his research and a total of eight experimental therapies. Even though Steinman eventually died from his cancer, he lived four and a half years, much longer than doctors had said he would. Which of the following is TRUE according to the article?
[ "Forssmann's experiment ended in failure.", "Forssmann had the pipe pushed all the way into his heart.", "Barry Marshall succeeded by drinking some Helicobacter pylori.", "Barry Marshall's experiment on himself confirmed that most doctors' belief about gastritis was correct." ]

It is not a good idea for children to have to work hard. Children should study in school as hard as they can. They should not have to do heavy work with their bodies. When parents or others force their children to work hard, the results are never good. Many may be very bad. If a farmer makes his son work like a man, he may easily learn to hate farming. Children sometimes do too much in gardens, in shops, or even in their own homes. They soon begin to hate such work with a force, because that can destroy their happiness. But there may be a worse loss, child's love for its parents. The feeling may become something different. When that happens, the old kind of love never returns. Children should not have to do _ work with their bodies.

As for older people, some of the applications are hard to use because they didn't grow up with them. They don't have simple models of how it should work. They don't know what to do when it doesn't work. I think there is huge potential, so I have designed some for them. The ability to connect to friends, who remember the same movies, news and music, is really important, especially as people get older. They end up in retirement homes and they aren't always close to their friends. Allowing the network to help them connect with friends and family members is a really powerful thing. My wife likes using the Internet, although it took me years to get her to use e-mail. She was born with normal hearing, but lost it when she was three years old. She was totally deaf for many years until 53 when she got ear implants .They work really well. That is a big change for her. Before then, her friends couldn't call her on the phone, so they insisted that she use e-mails to communicate with them. The younger people don't even think of this as technology. It's just there, and they use it .There's been a very interesting change in communication styles between the old and the young .A woman named Sharryturkle wrote about this phenomenon .There are some kids who are now in their teens and are tending not to make phone calls. And they think of e-mail as old-fashioned and slow. The reason why teens don't make phone calls seems to be that they don't know what to say. When they call they often pause for a while. On the other hand, texting is considered proper, and it's OK if you don't answer.

Vitamins are stored in foods we eat. The kids are udner great need of vitamins for growth. As they use their energy in playing, they need lots of vitamins. Children usually choose certain foods above the others and often do not eat those with important nutrients . Sothough the food they are eating is nutritious, it may not always provide all the nutrients the child needs. One nutrient can not balance the shortage of another. Foods like grains, vegetables, fruits and meats should be eaten daily, because different foods in the child's diet can balance against taking too much or too little of any nutrient. Kids grow slower in their childhood than when they were babies or when they develop into adults. Energy output is high, with hard paly perids that include plenty of running, jumping, and testing of new physical skills. So they need a lot of vitamins. Here are some important vitamins and their functions Vitamin D in milk helps your bones. Vitamin A in carrots helps you see at night. Vitamin C in oranges helps your body heal if you get a cut. B vitamins in leafy vegetables helps your body make protein . The children, who are suffering from a sickness called cystic fibrosis, lose vitamin A, D and E. These are main body-building vitamins. Therefore, vitamin supplements may be necessary. Blood tests will telll you whether a child needs vitamin supplements. If babies over nine months of age are receiving whole cow's milk, they'll need a daily vitamin C supplement till their diet provide enough vitamin C. Vitamin D is added to all milks so babies drinking them need no extra vitamin D. Children are greatly in need of vitamin C. If you are 18 years of age or younger, you should get 115 millgrams of vitamin C per day. Those over 19 should get 120 milligrams per day. When do kids have to take a vitamin supplement?

There are rolling hills and ivy-covered brick buildings. There are small classrooms, high-tech labs, and green fields. There's even a clock tower with a massive bell that rings for special events. Cushing Academy has all the characteristics of a New England school, with one exception. This year, after having had a collection of more than 20,000 books, officials have decided the 144-year-old school no longer needs a traditional library. They have decided to give away all their books. The future, they believe, is digital. "When I look at books, I see an outdated technology," said James Tracy, headmaster of Cushing. "We're not discouraging students from reading. We see this as a natural way to shape emerging trends and use technology. Instead of a traditional library, we're building a virtual library where students will have access to millions of books on the computer. We see this as a model for the 21st-century school." _ . Liz Vezina, a librarian at Cushing for 17 years, said she never imagined working as the director of a library without any books. "It makes me mad," said Vezina, who has made a career of introducing students to books. "I'm going to miss them, and there's something lost when they are done on a computer. There's sensual side to them -- the smell, the feel, the physicality of a book is something really special." Cushing is one of the first schools in the country to give up its books. William Powers, author of a book called the changes at Cushing "radical " and "a huge loss for students". "There are modes of learning and thinking that at the moment are only available from actual books," he said. "There is a kind of deep-dive reading that's almost impossible to do on a screen. Without books, students are more likely to do the quick reading that screens enable, rather than be by themselves with the author's ideas." What is special about Cushing Academy?

"I love the music-player function of 3G cellphones, " Xiaomei, a Chinese senior high school girl living in Japan, said happily. "Recently, I logged on to a website and downloaded some new Japanese songs with lyrics onto my 3G cellphone, "the girl said. "You know, it's amazing! Just like with KTV, _ 's voice can be switched-off leaving just the background music and lyrics. When no one is around, I practise singing songs like crazy. " Xiaomei's 3G cellphone almost made her a super star among her classmates. 3G was first introduced into Japan in 2001. After a slow start, it's now widely used there. High school students top the list of user groups, according to a major service provider in Japan. After years of effort, China is finally catching up. In January, China issued a 3G license to three operators--China Mobile, China Telecom and China Unicom. In 2009, the operators announced plans to expand the use of 3G cellphones. What is 3G? 3G wireless networks give users faster Internet connections. The Internet connection speed of 3G can be up to 15 to 20 times faster. This allows music and games to be downloaded more easily. E-mail can also be accessed faster. It has made watching movies and video-conferencing possible on a mobile phone. How do I use 3G? First, you must have a 3G cellphone. This year, products made by different cellphone companies will gradually appear in the marketplace. China Mobile and China Telecom users can continue using their old phone number and SIM card. China Unicom, however, has not yet decided on this matter. How much does it cost? The three operators have said that 3G fees will be similar, or slightly lower than today's 2G cellphones. According to a 3G student package, calls within the China Mobile network will cost 0.13 yuan per minute, while the fees go up to 0.23yuan per minute for calls between China Mobile and other networks. Which of the followings is NOT a benefit of 3G's high Internet connection speed?

Last night's meteor shower left many people in the community dissatisfied and demanding answers. According to Gabe Rothschild, Emerald Valley's mayor, people gathered in the suburbs of the city, carrying heavy telescopes, expecting to watch the brightly burning meteors passing through the sky. What they found instead was a sky so brightened by the city's lights that it darkened the light of the meteors passing overhead. "My family was so frustrated," admitted town resident Duane Cosby, "We wanted to make this an unforgettable family outing, but it turned out to be a huge disappointment." Astronomers--scientists who study stars and planets--have been complaining about this problem for decades. They say that light pollution prevents them from seeing objects in the sky that they could see quite easily in the past. They call on people and the government to take measures to fight against it. There is yet a population besides professional and amateur star observers that suffers even more from light pollution. This population consists of birds, bats, frogs, snakes, etc. For example, outdoor lighting severely affects migrating birds. According to the International Dark-Sky Association, "100 million birds a year throughout North America die in crashes with lighted buildings and towers." Countless more animal casualties result from the use of artificial lighting. Clearly, people enjoy the benefits of lighting their evenings. But some scientists think it can be harmful for humans, too. They worry that exposure to light while sleeping can increase a person's chances of getting cancer. Emerald Valley is only one community that is becoming aware of the negative effects of light pollution. For years, Flagstaff, Arizona, has enforced lighting regulations in its city in order to assist astronomers at the Lowell Observatory. Similar efforts have been made worldwide, and a movement is underway to remind us to turn off lights when we are not using them, so that other creatures can share the night.

First aid is the aid or the help which can be given to an injured person first, that is, before any other help comes. Nowadays there is usually a telephone not far away and the first we should do, if a serious accident happens, call the phone for an ambulance. Sometimes our quick action may save someone's life. Shock. People often suffer from shock after receiving an injury, sometimes even when the injury is very tiny. The face turns grey, and the skin becomes damp and cold. They breathe quickly. They should be kept warm. Cover them with a blanket and give them a warm drink. Broken bones. Do not move the patient. Send for an ambulance at once. Bleeding. A little bleeding doesn't harm. It washes dirt from the wound. But if the bleeding continues, try to stop it by placing a clean cloth firmly over the wound until the bleeding stops or helps arrive. Poison. A person who has taken poison should be taken to a hospital at once. With some poisons, sleeping pills, for example, it is a good thing to make the patient throw up by pressing your fingers down his throat. Remember: When an accident happens, send someone to telephone for an ambulance at once. Keep the injured person warm and quiet. Give him plenty of air. Do not let other people crowd around him. Which of the following statements is NOT true according to passage?

If you want to improve your child's results at school, you could do a lot worse than ensuring that they do plenty of exercise. Scientists have already shown that physical activity can make you brainier. But a team in America has used scans to show that an important part of the brain actually grows in children who are fit. These youngsters tend to be more intelligent and have better memories than those who are inactive. Scientists also found that one of the most important parts of their brains was 12 percent larger than those of unfit children. They believe that encouraging children to take exercise from a very young age could help them do better at school later. Researchers from the University of Illinois, in the U.S., studied the brains of 49 children aged nine and ten using a magnetic resonance imaging scan , a technique which provides very detailed pictures of organs and tissues in the body. They also tested the fitness levels of the children by making them run on a treadmill . The scientists found that the hippocampus, a part of the brain responsible for memory and learning, was around 12 percent larger in the fitter children. Professor Art Kramer, who led the study published in the journal Brain Research, said the findings had important implications for encouraging individuals to take part in sport from a young age. "We knew that experience and environmental factors and socioeconomic status all impact brain development," he said. "If you get some terrible genes from your parents, you can't really fix that, and it's not easy to do something about your economic status. But here's something that we can do something about." According to the passage, which of the following statements is NOT true?

Elderly people are growing healthier, happier and more independent, say American scientists. The results of a 14-year study to be announced later this month reveal that the diseases associated with old age are affecting fewer and fewer people and when they do suffer a stroke , it is much later in their life. In the last 14 years, the National Long-term Care Survey has gathered data on the health and lifestyles of more than 20,000 men and women over 65. Researchers, now analyzing the results of data gathered in 1994, say arthritis, high blood pressure and circulation problems -- the major medical complaints in this age group -- are troubling a smaller proportion every year. And the data confirms that the rate at which these diseases are declining continues to increase. Other diseases of old age -- dementia, strokes, arteriosclerosis and emphysema -- are also troubling fewer and fewer people. "It really raises the question of what should be considered normal ageing," says Kenneth Manton, a demographer from Duke University in North Carolina. He says the problems doctors accepted as normal in a 65-year-old in 1982 are often not appearing until people are 70 or 75. Clearly, certain diseases are beating a retreat in the face of medical advances. But there may be other contributing factors. Improvements in childhood nutrition in the first quarter of the twentieth century, for example, gave today's elderly people a better start in life than their former generations. On the downside, an increase in some cancers and bronchitis may reflect changing smoking habits and poorer air quality, say the researchers. "These may be subtle influences," says Manton, "but our subjects have been exposed to worse and worse pollution for over 60 years. It's not surprising we see some effect." One interesting correlation Manton uncovered is that better-educated people are likely to live longer. For example, 65-year-old women with fewer than eight years of schooling are expected, on average, to live to 82. Those who continued their education live an extra seven years. Although some of this can be attributed to a higher income, Manton believes it is mainly because educated people seek more medical attention. The survey also assessed how independent people over 65 were, and again found a striking trend. Almost 80% of those in the 1994 survey could complete everyday activities ranging from eating and dressing unaided to complex tasks such as cooking and managing their finances. That represents a significant drop in the number of disabled old people in the population. According to Manton, slowing the trend has saved the United States government's medicare system more than $200 billion, suggesting that the ageing of America's population may prove less of a financial burden than expected. But independence can have drawbacks. Scientists found that elderly people who felt emotionally isolated maintained higher levels of stress hormones even when asleep. The research suggests that older people live best when they feel independent but know they can get help when they need it. What is the main topic of this passage?

Tu Youyou, 84, honored with the Nobel Prize in Physiology or Medicine on Oct 5, 2015. She was the first Chinese citizen to win a Nobel Prize in science for her work in helping to create an anti-malaria medicine. In 1967, Communist leader Mao Zedong decided there was an urgent national need to find a cure for malaria. At the time, malaria spread by mosquitoes was killing Chinese soldiers fighting Americans in the jungles of northern Vietnam. A secret research unit was formed to find a cure for the illness. Two years later, Tu Youyou was instructed to become the new head of Mission 523. Researchers in Mission523 _ ancient books to find historical methods of fighting malaria. When she started her search for an anti-malarial drug, over 240,000 compounds around the world had already been tested, without any success. Finally, the team found a brief reference to one substance, sweet wormwood , which had been used to treat malaria in China around 400 AD. The team isolated one active compound in wormwood, artemisinin , which appeared to battle malaria-friendly parasites . The team then tested extracts of the compound but nothing was effective until Tu Youyou returned to the original ancient text. After another careful reading, she improved the drug recipe one final time, heating the extract without allowing it to reach boiling point. After the drug showed promising results in mice and monkeys, Tu volunteered to be the first human recipient of the new drug. "As the head of the research group, I had the responsibility." she explained. When did Ms. Tu start her malaria research?

But what motivated me to get serious about it was turning 30. I weighed 414 pounds. I was always tired. Some of my family members have suffered from heart disease,and I was scared. I also wanted to look better. So after my birthday,I walked into the office of a weightloss doctor. She was very understanding. Her focus was on balanced meals and she wanted me to exercise. Walking was all I could do at first. I started by walking a few blocks and gradually increased the distance,until one weekend,I found myself saying,"Wow,this seems pretty easy." So I started to run. I was losing nine or ten pounds a month,and I had more energy. I started to think about the New York City Marathon. For years,I watched the runners and thought,"This looks like fun,but I could never do that." But now I realized that maybe I could. I joined the New York Road Runners. I ran a 10km,then a halfmarathon. I still wasn't confident I could run a full 26 miles. But I told myself I was going to do it,no matter what. By my 33rd birthday,I was down to 180 pounds. I started formally training for the marathon. And on the morning of November 1,I stood on the Verrazano Bridge in Staten Island with more than 40,000 other runners,waiting for the event to start. It was unbelievable to have the audience cheering me on,handing me cups of water. And I crossed the finish line. My friends sprayed (......) me with beer,as if I'd won the Super Bowl.

Teenagers with a bedroom television tend to have poorer diet and exercise habits and lower grades in school than those without one, US researchers said on Monday. While many studies have examined TV viewing habits of young people, researchers at the University of Minnesota School of Public Health said little had been known about the effects in particular for older teenagers of having a bedroom TV. They questioned 781 teenagers, aged 15 to 18, in the Minneapolis area in 2003 and 2004. Of them, 62 % reported having a television in their bedroom. Not surprisingly, those with a bedroom TV were more likely to watch it a lot, clocking four to five more hours in front of a television per week, the researchers said. Many more teens with a bedroom TV were classified as heavy TV watchers than those without one. Girls with a bedroom television reported getting less exercise -- 1.8 hours per week compared to 2.5 hours for girls without a TV. They also ate fewer vegetables, drank more sweetened drinks and ate meals with their family less often. Boys with a bedroom TV reported having a lower grade point average than boys without one, as well as eating less fruit and having fewer family meals. "It is clearly important not to allow your child to have a TV in the bedroom," said Daheia Barr-Anderson, one of the researchers. "When you upgrade your TV in the living room and you have this smaller TV that's out of date but still usable, you should really resist putting it in one of your children's bedrooms," she said in a telephone interview.

Dust on furniture may be bad news for waistlines . But it's far too early to add dusting to a weight-loss plan. Dietary fats and other materials that make up indoor dust can send a signal to human fat cells, telling them to grow. That process, in turn, might slow the body's rate of burning energy. Such changes could add to any weight problems a person might have. "We don't know what that means to long-term health and certain diseases yet," says Heather Stapleton, one of the study's authors. But she notes that her team's findings also raise a question of whether pollutants in dust might play some role in the growing, global problem of obesity . Stapleton and her colleagues collected dust from homes and offices. Studies found that some materials in the dust could turn on a protein called PPAR-gamma 1. It's found in many human tissues. Turning this protein on can cause fat cells to grow. Researchers think this protein may be involved in obesity. But a second study now finds evidence that certain fats are mostly to blame. Cooking oils may send out some of these fats into the air, where they eventually find their way into house dust. Or, the authors say, the fats might enter house dust as part of the hair or skin cells shed by people or pets. "While the findings are amazing," says Mitchell Lazar, another study author, "these findings need to be taken as very limited."

More and more Chinese mainland buyers have in the past few weeks been queuing to cross the border into Hong Kong to _ growing financial pressure led by rising food prices at home. Their shopping baskets are full of sugar, salt and even tissue paper. While prices are rising so fast, many people are worrying out ways to cut down their expenses. Du Zhenqi, an 80-year-old Beijinger, grows different vegetables in the community yard. But this year, before they turned ripe, they were all picked by his neighbors. "The prices of vegetables have gone up dramatically," said Du. "So I understand those people and it pleased me to offer them my help." Du expressed his sympathy for these who took away his vegetables without permission. The rise of food price in China has made people with low incomes feel serious financial pressure and forced them to spend wisely. A collection of practical money-saving tips is thus becoming increasingly popular among Chinese citizens. If you search "money-saving strategies" in Baidu, you will find 4.27 million entries in 0.19 seconds. The collection provides tips such as choosing local and seasonal products, avoiding buying vegetables on rainy or snowy days when higher transport costs increase prices, using websites for purchases, and planting vegetables on the balcony. Some consider buying in large quantity to stay within a tight budget. Fei Yuqin, who lives in Shanghai, frequently hurries to a farmers' market before 6 a.m. to buy large amounts of vegetables for her family and neighbors. "Instead of buying small amounts, I buy large amounts of vegetables at the market and get a 50-percent discount." With these tips, many people have become experts in cutting household expenses. However, financial pressure caused by the current round of price rising still troubles many Chinese people. Which of the following is TRUE?

If you're ever apart from your children, a new study says just talking on the phone will help just as much as a hug . If you're a parent who spends long hours on the job, you probably feel sorry for spending so much time away from your kids. But the results of a new study show that a mother's voice alone can be just as comforting to an anxious child as physical contact . In an experiment, researchers from the University of Wisconsin-Madison asked a group of girls between the age of 7 and 12 to solve math problems in front of judges --- a stressful situation for anyone. Before the girls were set to solve math problems, the researchers measured their levels of two hormones : cortisol, which goes up during stressful periods, and oxytocin, the "love" hormone. After they were finished, some of the girls got to meet up with their mothers right away. The mums came in and hugged the girls. Another group of the girls didn't see their mothers, but received phone calls from them, in which their mothers told them how well they'd done. The final group had no contact with their mothers, but watched an animal movie, March of the Penguins instead. Finally, the girls' hormone levels were measured again. Although the movie was interesting, it did nothing to ease the children's anxiety ---- but, surprisingly, both the physical contact and phone calls from their mothers had the same effect on easing the girls' stress levels. So, no matter how old you are, if you're feeling stressed about something in your life, a phone call to Mom might be just the key to help you feel better.

How do you remember the way to your house? Where do dreams come from? It is your brain that does these things. A British scientist showed that "sleep can improve one's memory." It's not a dream for students to study when they sleep. In fact, your brain is working day and night. If you learn words before bed, a certain part of the brain may help you to remember the words while you sleep. What's more, another scientist in the USA found that there was a "talent button " in the human brain. It might make a person more talented. There are more interesting things about the brain. Your brain uses less energy than a fridge light. Just two bananas can give the brain enough energy to work for a whole day. According to some scientists, yawning keeps our brains "cool", which makes us think quicker. Here are some pieces of advice to keep a good brain: Eat healthy food. Get a lot of playtime or exercise.

Cancer is among the top killer diseases in our society today and scientists have found out that stress helps to bring it on. We need to consider, therefore, what are the causes of stress in our life, and whether we can do anything about them. Are we under-employed, or overburdened with too many responsibilities? Do we have a right balance of work and leisure in our lives? Are our relationships with family, friends or fellow workers all that they should be? All these things can be a cause of stress, and it is best to face them directly, and to bring our frustrations into the open. People who have a good _ and then forget it are doing their health more good than those who bottle up their feelings. If our self-examination has brought any causes of stress to light, let us consider what we can do about them. It is possible to change jobs. We can make more leisure and fill it more happily, if we will accept a different living standard. We can improve our personal relationships by a different attitude. It is we who allow other people to make ourselves unhappy. Often the little things that disturb us are not worth an hour's anger. The teaching in the Bible "Let not the sun go down upon your wrath " is good advice from the health point of view as well as religion. Which of the following statements is true?

Autumn and winter are cold and flu seasons. Will the old advice about dressing warmly help prevent a cold, or if you get sick, should you follow the old saying, "feed a cold and starve a fever?" And what about that fever? Should you take medicine to reduce your temperature, or is it better to let the body treat the fever itself? Everyone seems to have an answer. But is popular wisdom valuable? Doctor Nelson knows a lot about cold and flu seasons. Nelson says research may be just starting to provide proofs for long-held beliefs. For example, scientists for years were against the idea that getting cold and wet might cause colds or flu. But recent studies have shown that cold temperatures cause stress on the body, and that stress can create conditions more inviting to viruses. So maybe it does make sense to wrap up warmly before going outside. And what about feeding a cold and starving a fever? Nelson says if you have a cold and are hungry, you should eat. But a fever, especially a high one, suggests a more serious problem. He says people are usually not hungry when they have a high fever. Eating might even make a person sick. But drinking enough water is important. A fever easily makes the body lose water. Finally, when should you treat a fever? Nelson says a fever should be treated if it stays at 40degC or above for a day or more. A high temperature can damage brain cells. The doctor also believes in treating a fever if it prevents a person from sleeping. Medicine like aspirin, for example, can be used to reduce pain and fever. But aspirin should not be given to children because it can cause serious problems. We can learn from the passage that Doctor Nelson _ .

The reason why women love to spend hours in shops while men prefer to be in and out of the high street in minutes can trace back to their hunter-gathering past, find scientists. While women spent their days gathering food, often with children, men were hunters who made plans about how to catch and kill their prey . These two ways of getting food in the past show how we shop in modern times, the study believes. Women would spend hours trying to find the right things, because they had in the past spent ages trying to find the best quality and health-giving food. Men, on the other hand, decided in advance what animal they wanted to kill and then went looking for it. Once it was found and killed, they returned home. Daniel Kruger, professor of the University of Michigan, said the study could be the answer to why there are a lot of _ when couples go shopping together. He said it could also help couples to avoid fights in the shops if they understood the reasons why each sex had different ways of deciding on the perfect present. "In modern times, women are much more likely than men to know when a specific type of item will go on sale. Women also spend much more time choosing the perfect color and texture." Professor Kruger said his study was important because if men and women understood each other's shopping habits they could avoid arguments while shopping. What has decided the different shopping habits of men and women?

"Teenager" is the new term being used in the UK to describe kids at either 8--12 or 10--13 years old. More and more companies are beginning to create products and services for teenagers. The Disney Company sells music and film to teenagers and their parents. You can get everything from lunchboxes and mobile phone covers, to monthly fan magazines and clothing. It's all about sales, which suggests that teenagers must have more money, freedom and influence upon their parents than they've ever had before. Most kids in the UK today get more pocket money than kids did ten years ago. Parents have more money to give their kids than before, since parents are having fewer children. In addition, the divorce rate in the UK is continually rising and parents spend less time with their children than they used to, so many parents try to please their children by buying them presents. It's a bad habit for both parents and kids to get into, but parents are under pressure from commercial marketing and the pleas of their children. UK kids today are very media and computer-literate. A lot of kids have a TV, if not a computer, in their bedrooms. They have easy access to much more information about life and the world. They may have experienced a lot in life as well, since 24% of UK kids live in single-parent families, so people now say that "kids are getting older younger". With such maturity at such a young age, it's no wonder teenagers are able to influence their parents and have more freedom than previous generations. UK teenagers never used to be worried about spending money on clothes. That's changed. Now, they are much more fashion conscious and concerned about their image . Many of them outgrow the bright colors and fashions of kids years ago and go for something darker and more rebellious . Surely none of the above is a good thing. The UK government is certainly concerned, and for that reason has strict laws preventing companies from marketing their products and services at children.

What would it take to persuade you to exercise? A desire to lose weight or improve your figure? To keep you away from diseases? To live to a healthy old age? You'd think any of those reasons would be enough to get Americans exercising. Yet a vast majority of Americans have thus far failed to swallow the "exercise pill". Now a research by psychologists strongly suggests it's time to think of current well-being and happiness as motivators for exercise instead of future health, weight loss and body image. Dr. Segar, one of the researchers, believes that immediate rewards are more motivating than distant ones. "People who say they exercise for the quality of life exercise more over the course of a year than those who say they value exercise for its health benefits." He said. ' Other studies have shown that what keeps people moving depends on age, sex and life circumstances. For those of college age, physical attractiveness typically heads the list of reasons to begin exercising, although what keeps them going seems to be the stress relief that a regular exercise program provides. The elderly, on the other hand, may get started because of health concerns. But often what keeps them exercising are the friendships and sense of community that may otherwise be missing from their lives. Improving daily well-being is the most influential factor for the women. Men indicate they are motivated by more distant health benefits, but this may be because men feel less comfortable discussing their mental health needs. "Exercise should be encouraged but the emphasis on weight loss, disease prevention and healthy aging should be reduced." Dr. Segar concluded. "Exercise can make people feel more energetic, less stressed and, yes, happier." What is the author mainly arguing in the passage?

Xinhua Sept.25,2008 JIUQUAN, Gansu---China launched successfully its third manned spacecraft on Thursday with three astronauts on board to attempt the country's first-ever space walk. The spaceship Shenzhou VII blasted off on a Long March II-F carrier rocket from the Jiuquan Satellite Launch Center in the northwestern Gansu Province at 9:10pm.after a breathtaking countdown to another milestone on China's space journey. On board pilots Zhai Zhigang, Liu Boming and Jing Haipeng are expected to orbit the earth for three days, when one of them will float out of the cabin about 343 kilometers above the earth. When they make it, China will become the third country in the world who is able to conduct extravehicular activity (EVA) in space following the former Soviet Union and the United States. President Hu Jintao watched the historic moment at the launch center, joined by Chinese experts and other work staff. Hu briefly met the trio astronauts before they entered the spacecraft Thursday afternoon, wishing them "a complete success in this glorious and sacred mission". "During the mission, you will carry out China's EVA with homemade EVA space suit, which is a great leap for China's space technology." said Hu. Other tasks of the Shenzhou VII crew include the release of a small monitoring satellite and a trial of the data relay of the satellite Tianlian-I. If successful, the mission would be of great significance to the country's future plans to build a space lab and a space station, said ZhangJianqi, deputy chief commander of the manned space project. What is the great leap for China's space technology during the space journey?

When dinning in restaurants, Americans usually order drinks first, then soup, salad, main course or entree , and dessert at last. This is somewhat a different order way from that in Europe. Until about the middle of the nineteenth century, Americans didn't have to worry about whether the salad came before or after the main course since they didn't eat salad at all. Chomping on greens was once considered sissy , and Americans preferred to get their greens indirectly, after they had been processed by rabbits or deer. The shift of public taste toward the salad may be attributed to New York's Delmonico brothers, who originally introduced smorgasbord from Europe, and served it in their restaurant. Such novelties became so popular that by the end of the nineteenth century, the Waldorf salad has swept the country. Europeans still chomp on greens after the main course, as a way of clearing the palate , and being ready for the cheese. Why Americans eat their salad first is uncertain. The following joking suggestions might make sense: The custom may be related to the slimming craze, for "salad first" may fill you up without any worry about fattening; to avoid customers' impatience with waiting, the restaurant serves salad first to keep them busy while the main courses are being prepared; eating raw food while one is waiting for the cooked food may be a way of announcing that one is not wasting time, which is seen as a virtue; probably unfair to the restaurant, this custom has been encouraged by the merchant as trick-the meagerness of a meal is less noticeable if it comes after "free" salad-after all, rabbit food is much cheaper than the rabbit. Before the middle of the nineteenth century, _ .

My daughter Allie is leaving for college in a week. Her room is piled with shopping bags filled with blankets, towels, jeans, sweaters. She won't talk about going. I say, "I'm going to miss you," and she gives me one of her looks and leaves the room. Another time I say, in a voice so friendly it surprises even me: "Do you think you'll take your posters and pictures with you, or will you get new ones at college?" She answers, her voice filled with annoyance, "How should I know?" My daughter is off with friends most of the time. Yesterday was the last day she'd have until Christmas with her friend Katharine, whom she's known since kindergarten. Soon, it will be her last day with Sarah, Claire, Heather... and then it will be her last day with me. My friend Karen told me, "The August before I left for college, I screamed at my mother the whole month. Be prepared." I stand in the kitchen, watching Allie make a glass of iced tea. Her face, once so open and trusting, is closed to me. I struggle to think of something to say to her, something meaningful and warm. I want her to know I'm excited about the college she has chosen, that I know the adventure of her life is just starting and that I am proud of her. But the look on her face is so mad that I think she might hit me if I open my mouth. One night -- after a long period of silence between us -- I asked what I might have done or said to make her angry with me. She sighed and said, "Mom, you haven't done anything. It's fine." It is fine -- just distant. Somehow in the past we had always found some way to connect. When Allie was a baby, I would go to the day-care center after work. I'd find a quiet spot and she would nurse -- our eyes locked together, reconnecting with each other. In middle school, when other mothers were already regretting the distant relationship they felt with their adolescent daughters, I hit upon a solution: rescue measures. I would show up occasionally at school, sign her out of class and take her somewhere -- out to lunch, to the movies, once for a long walk on the beach. It may sound irresponsible, but it kept us close when other mothers and daughters were quarrelling. We talked about everything on those outings -- outings we kept secret from family and friends. When she started high school, I'd get up with her in the morning to make her a sandwich for lunch, and we'd silently drink a cup of tea together before the 6:40 bus came. A couple of times during her senior year I went into her room at night, the light off, but before she went to sleep. I'd sit on the edge of her bed, and she'd tell me about problems: a teacher who lowered her grade because she was too shy to talk in class, a boy who teased her, a friend who had started smoking. Her voice, coming out of the darkness, was young and questioning. A few days later I'd hear her on the phone, repeating some of the things I had said, things she had adopted for her own. But now we are having two kinds of partings. I want to say good-bye in a romantic way. For example, we can go to lunch and lean across the table and say how much we will miss each other. I want smiles through tears, bittersweet moments of memory and the chance to offer some last bits of wisdom. But as she prepares to depart, Allie has hidden her feelings. When I reach to touch her arm, she pulls away. She turns down every invitation I extend. She lies on her bed, reading Emily Dickinson until I say I have always loved Emily Dickinson, and then she closes the book. Some say the tighter your bond with your child, the greater her need to break away, to establish her own identity in the world. The more it will hurt, they say. A friend of mine who went through a difficult time with her daughter but now has become close to her again, tells me, "Your daughter will be back to you." ks5u "I don't know," I say. I sometimes feel so angry that I want to go over and shake Allie. I want to say, "Talk to me -- or you're grounded!" I feel myself wanting to say that most horrible of all mother phrases: "Think of everything I've done for you." Late one night, as I'm getting ready for bed she comes to the bathroom door and watches me brush my teeth. For a moment, I think I must be brushing my teeth in a way she doesn't approve of. But then she says, "I want to read you something." It's a brochure from her college. "These are tips for parents." I watch her face as she reads the advice aloud: " 'Don't ask your child if she is homesick,' it says. 'She might feel bad the first few weeks, but don't let it worry you. This is a natural time of transition. Write her letters and call her a lot. Send a package of candies...' " Her voice breaks, and she comes over to me and buries her head in my shoulder. I stroke her hair, lightly, afraid she'll run if I say a word. We stand there together for long moments, swaying. Reconnecting. I know it will be hard again. It's likely there will be a fight about something. But I am grateful to be standing in here at midnight, both of us tired and sad, toothpaste spread on my chin, holding tight to--while also letting go of--my daughter who is trying to say good-bye. Why is there a period of silence between the author and Allie one night?

People diet to look more attractive.Fish diet to avoid being beaten up,thrown out of their social group,and getting eaten as a result.That is the fascinating conclusion of the latest research into fish behavior by a team of Australian scientists. The research team have discovered that subordinate fish voluntarily diet to avoid challenging their larger competitors."In studying gobies we noticed that only the largest two individuals,a male and female,had breeding rights within the group," explains Marian Wong."All other group members are nonbreeding females,each being 5-10% smaller than its next largest competitor.We wanted to find out how they maintain this precise size separation." The reason for the size difference was easy to see.Once a subordinate fish grows to within 5-10% of the size of its larger competitor,it causes a fight which usually ends in the smaller goby being driven away from the group.More often than not, _ is then eaten up. It appeared that the smaller fish were keeping themselves small in order to avoid challenging the boss fish.Whether they did so voluntarily,by restraining how much they ate,was not clear.The research team decided to do an experiment.They tried to fatten up some of the subordinate gobies to see what happened.To their surprise,the gobies simply refused the extra food they were offered,clearly preferring to remain small and avoid fights,over having a feast. The discovery challenges the traditional scientific view of how boss individuals keep their position in a group.Previously it was thought that large individuals simply used their weight and size to threaten their subordinates and take more of the food for themselves,so keeping their competitors small. While the habits of gobies may seem a little mysterious,Dr.Wong explains that understanding the relationships between boss and subordinate animals is important to understand how hierarchical societies remain stable. The research has proved the fact that voluntary dieting is a habit far from exclusive to humans."As yet,we lack a complete understanding of how widespread the voluntary reduction of food intake is in nature," the researchers comment."Data on human dieting suggests that,while humans generally diet to improve health or increase attractiveness,rarely does it improve long-term health and males regularly prefer females that are fatter than the females' own ideal." When a goby grows to within 5-10% of the size of its larger competitor,it _ .

Most of us think that when we step under a shower we're getting clean.We are, but we're also giving a home to lots of tiny little creatures we didn't even know about. A showerhead carries thousands of bacteria called Mycobacterium.These can cause problems like coughs and tiredness, and a general feeling of poorliness .When you turn on the water, the bacteria go from the showerhead onto and into your body. This is a finding of Norman R.Pace and his team at the University of Colorado, in the US.The scientists investigated bacteria in all kinds of human environment, including showers. Pace's team looked at 45 showerheads in nine American cities.They discovered that 30 percent of them had large amounts of flying Mycobacterium. But Pace said that they pose few threats to the health.Only those with a frail immune system might need to worry. He told the New York Times that the bactertia are not as unpleasant as might be thought.He said that having a shower is no more dangerous than anything else we do in the morning. But for those who feel sick about the idea of all those microorganisms , he had some advice. Let the water run for 30 seconds before getting into the shower.Why? The number of bacteria is smaller than when the water is just turned on.If that seems like a waste of water, he added that you could also change your showerhead every few months. But Pace had good news too.He has also been testing the air in US subways.Apart from iron particles , which are ground off the track by the wheels of trains, subway air is fresh.The reason is that a train's movement pumps fresh outdoor air into the tunnels . Pace explained that he wanted to understand the natural microbial environments of public places.This kind of knowledge might help _ the microbes to be used in a bioterrorist attack.

I smiled and told her,"It's OK."Then I talked to the boy,"Hi,I'm Dory Kramer. How are you?" He studied me from head to toe,and asked,"Are you a little mommy?" "Yes,I have a son," I answered. "Why are you so little?"he asked. "It's the way I was born," I said."Some people are little. Some are tall. I'm just not going to grow any bigger."After I answered his other questions,I shook the boy's hand and left. My life as a little person is filled with stories like that. I enjoy talking to children and explaining why I look different from their parents. It takes only one glance( ) to see I'm different. I stand three feet nine inches tall(="1.14" metres).I was born adwarf.In spite of this,I did all the things other kids did when I was growing up. I didn't realize how short I was until I started school. Some kids called me names .Then I knew. I began to hate the first day of school each year. But I learned to smile and face the fact that I was going to be noticed my whole life.What I lacked in height,I made up for in personality.When people are rude,I remind myself,"Look what else I have-a great family,nice friends." Why did the mother say sorry to Dory Kramer?

"An apple a day keeps the doctor away." Similarly, if we drink a little more water ever day, we may find that we need to go to the doctor a lot less often. A healthy diet is made up of water and a great many different kinds of foods. We know that healthy foods like fruits, vegetables and fish, are important as they provide us with energy and fibre, without giving us too much fat and sugar. But why is water important? The human body needs water to survive. Water is important as it carries poisons and waste out of our bodies. However, doctors advise us to drink plenty of water, much more than the small amount we need to stay alive. Some doctors believe that water is important for our health in all kinds of ways. They believe that a great many illnesses and health problems stars as a result of dehydration--a lack of water in the body. Most people are dehydrated at least some of time, although they probably don't know it. It is surprising to learn that if we feel thirsty, we are already in the first stages of dehydration. In fact, we are advised to drink water before we feel thirsty. These doctors think that health problems such as headaches, high blood pressure and asthma could be helped if people drink more water. They also believe that drinking more water can help people who are overweight. Water contains no calories so it will not make us put on weight. If we drink water, we will probably drink less sugary soft drinks such as Coca-cola. Doctors also believe that drinking more water may stop people from overeating. They say that many people think that they are hungry when they are, in fact, thirsty. Doctors suggest, therefore, that we eat less food and drink more water. There are still many health problems that cannot be solved by drinking water, so we should not stop going to seeing the doctor completely. However, if we make a decision to drink water every day, we may find that we need to go to the doctor a lot less often. Lack of water caused people to put on weight too much because _ .

Almost a decade after the hit Finding Nemo made clownfish seem totally warm and lovable, environmentalists are now looking for a real-life sequel: Saving Nemo. In the United States, a request has been made to extend the protections of the Endangered Species Act to marine species including the clownfish. But before you start shedding tears for Nemo and his buddies, keep in mind that this request is not based on any evidence of a decline in the clownfish population. Instead, what has sparked concern is the worsening health of coral reefs, which more than one million aquatic species including the clownfish depend on to thrive, even survive. In ways it makes more sense to move to protect a species when its habitat declines rather than its actual population. The most important mission of the Endangered Species Act is the protection of species' habitats; without their habitats, there's almost no hope of saving endangered animals, except perhaps in a zoo. Earlier this year, alarming news came about the world's largest coral reef system, Australia's Great Barrier Reef (GBR,). A study has shown the Reef is in sharp decline, with half of its coral cover gone in the past 27 years. Katharina Fabricius, an Australian coral reef ecologist co-authoring the study, has been diving and working on the GBR since 1988--and has watched the decline. "There are still a lot of fish ... but not the same color1 and diversity as in the past," she said. The study team used information from more than 2,000 surveys to determine the rate of decline between 1985 and 2012. That overall 50-percent decline, they estimate, is a yearly loss of about 3.4 percent of the Reef. If the trend continued, the coral cover could halve again by 2022. Several main factors are responsible for the decline, the study found. Intense tropical cyclones , believed to be fueled by global warming, have caused massive damage to reefs in the central and southern parts of the Reef. Meanwhile, population explosions of the coral-consuming crown-of-thorns starfish have affected coral populations along the length of the Reef. Two severe coral bleaching events, caused by ocean warming, have also had major damaging impacts in northern and central parts of the GBR. A request has been made in the United States to save the clownfish because _ .

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. According to the passage, some people think that if you don't have breakfast, you will _ .

Have you ever been talking to somebody at the party? Do you focus entirely on the person you are speaking with or does your attention keep jumping around the room to all the other people there? Generally speaking, if the person is someone you really want to talk to you will focus on them. Most other people will only get about half of your attention. You may think that this is OK, because if you don't really want to talk to them then what does it matter if you don't give them your full attention? Consider two things. First, you may just not realize the importance of that conversation. If you are at a networking meeting and you hope to meet the CEO of Company X but you end up talking to someone who has a low-level job at a different company, then you may let your attention wander as you speak to him. But maybe you don't realize that this person has already met the CEO and could introduce you. Do you think he will do that if he feels you don't really care about speaking to him? This doesn't mean you need to spend the entire time talking to him. Five or ten minutes of real attentive conversation can be worth 30 minutes to an hour of partial attention interaction. Second, whether you want to speak to someone changes based on the situation. You love your spouse , but if he or she tries to talk to you while you are watching something you like on TV, where is your attention going? Make your own decision, but if you want them to feel valued, give them your 100% attention. "The nice thing is that in many cases you can give them your attention for a few minutes and then return to what you were doing. You miss very little, they feel valued, and all is good." Generally speaking you would like to focus on someone _ .

How to Beat On-line Credit-card Thieves The Internet has led to a huge increase in credit-card fraud. Your card information could even be for sale in an illegal web site. Web sites offering cheap services should be regarded with care. On-line shoppers who enter their credit-card information may never receive the goods they thought they bought. The thieves then go shopping with your card number--- or sell the information over internet. Computers hackers have broken down security systems raising questions about the safety of cardholder information. Several months ago, 25,000 customers of CD Universe, and on-line music retailer , were not lucky. Their name, addresses and credit-card numbers were posted on a web site after the retailer refused to pay US $157,828 to get back the information. Credit-card firms are now fighting against on-line fraud. Master-card is working on plans for Web-only credit card, with a lower credit limit. The card could be used only for shopping on-line. However, there are a few simple steps you can take to keep from being cheated. Ask about your credit-firm's on-line rules. Under British law, cardholders are responsible for the first US $78 of any fraudulent spending. And shop only at secure sites: Send your credit-card information only if the web site offers advanced secure system. If the security is in place, a letter will appear in the bottom right-hand corner of your screen. The web site address may also start the extra "s" stands for secure. If you still have any doubt, give your credit-card information over the telephone. Keep your password safe: Most on-line sites require a user name and password before placing an order. Treat your password with care. What do most people worry about the Internet according to this passage?

I have two kids, a boy and a girl. I don't worry about my girl; I'm sure she'll be well trained in mixed martial arts. I worry about my son. I'm pretty sure he's going to be feminine . Sorry to say that, but let's face it. No dad wants his son to go feminine. At the rate we're moving in a couple of years you won't be able to tell the difference between boys and girls. Sound extreme? Think about this. In every movie where advanced time-traveling beings come to our planet, there's one constant: You can't tell the male aliens from the female aliens! But that's the future. Kids today are soft and fat. People ask why. Is it junk food? No. Junk food has been around for fifty years. Is it video games? No. Video games have been around for thirty years. None of the kids playing them back in the day were terribly obese. We're all scratching our heads trying to figure out what we've introduced to society to ruin our kids. But it's not anything we've added that has ruined our kids. It's stuff we've gotten rid of. Take the gym rope for example. Remember that thing that stretched from the floor to the ceiling in your gym class that you could never climb? Most of the kids couldn't make it to the top. But that wasn't the point; the point was you had to try while some middle-aged guy who couldn't make it up a flight of stairs shouted at you. We should have put our son on that rope, and given him a head start. But we didn't want to shame the boy, so we took it down. Taking down the rope would be a good idea if there were no ropes in life. But they're everywhere. You just can't see them. They're in every goal unrealized and expectation not met. The point everyone missed about the rope is you weren't supposed to make it to the top. It was there to create a fire that burned in the oversize belly of every kid. What causes kids today to be soft and fat?

Alzheimer's disease affects millions of people around the world. American researchers say the disease will affect more than one hundred million people worldwide by the year twenty fifty. That would be four times the current number. Researchers and doctors have been studying Alzheimer's patients for a century. Yet the cause and the cure for the mental sickness are still unknown. However, some researchers have made important steps towards understanding it. Several early signs of the disease involve memory and thought processes. At first, patients have trouble remembering little things. Later, they have trouble remembering more important things, such as the names of their children. There are also some physical tests that might show who is at risk of developing Alzheimer's disease. The tests look for proteins in brain and spinal cord fluid. The proteins appear to be found only in people with the disease. The protein tests correctly identify the presence of the disease in about ninety percent of patients. Now, a much simpler physical test to predict Alzheimer's risk has been developed. Researchers found that trouble with the sense of smell can be one of the first signs of Alzheimer's. Using this information, they developed a test in which people were asked to identify twelve familiar smells. These smells included cinnamon, black pepper, chocolate, paint thinner, and smoke. The study continued for five years. During this period, the same people were asked to take several tests measuring their memory and thought abilities. Fifty percent of those who could not identify at least four of the smells in the first test had trouble with their memory and thinking in the next five years. Another study has shown a possible way to reduce a person's chances of developing Alzheimer's disease in old age. Researchers in Chicago found that people who use their brains more often are less likely to develop Alzheimer's disease. Those who read a newspaper, or play chess or word games are about three times less likely to develop the condition. Researchers say they still do not know what causes Alzheimer's disease. But they say these findings might help prevent the disease in the future. Whats the main idea of the passage?

As we all know, getting benched in sports is usually a bad thing. But at one school in Florida, a girl has taken a bench and turned it into something entirely different - a place to find friends. It's called the Friendship Bench. And it's the brainchild of a sixth grader at Palm Bay Elementary - a girl named Acacia Woodley. Acacia's attitude toward life might be summed up best by a question she recently asked members of the Brevard County School Board - "what if we spend as much time putting the spotlight on kindness as we do on cruelty?" It's a philosophy Acacias has learned to live her own life -despite having a lot of people would consider a handicap. She was born without a right hand. And her left hand did not form properly. But Acacia says that she has not stopped her from achieving her goals. "You need to believe in your dreams. If you don't believe in you dreams, I can definitely tell you that they are not going to come true." She said. Acacia came up with the idea for the Friendship Bench after seeing kids getting bullied at school. She says she has also experienced bullying herself - kids whispering about her or picking on her because she is different. "Some people say they feel sorry for me. I tell them not to," she said. "I don't care that I'm different. I like being different." The Friendship Bench looks like a lot of other benches. It has arm sets and a place to lean on. But there are also words painted on it - words such as "hope", "respect", "listen" and "dream". Acacia put the benches together with the help from her mother and brother. Any time a kid feels he or she needs a friend, all that kid needs to do is sit on the bench. It is then up to the other kids - or grown-ups - to fill that need. "It's a perfect idea," Palm Bay Elementary Principal Lori said. "It's something we've needed so badly." The Friendship Bench has been such a success at Palm Bay Elementary that other schools are now interested in installing one too. "There's a saying in my teacher's classroom," Acacia said. "It says, 'it you can dream it, you can achieve it.'" What can be learned about Acacia from the passage?
[ "She is disabled but leads an active life.", "She has a deep understanding of life.", "She finds it difficult to achieve her goals.", "She finds herself always in need of help." ]
