mmlu_train_43059 | Many children would start school hungry without breakfast clubs, teachers have claimed. A new survey suggests these clubs are the only way many students can get a meal before lessons. About 54% of the 552 school staff questioned by the Association of Teachers and Lecturers(ATL)said their school provides a breakfast club for pupils. The biggest reason for them to attend these clubs is that their parents or carer goes to work early, cited by 76.8% of those questioned. About 22.6% said children attended due to lack of money at home because parents or carers are unemployed and 15.2% said lack of money at home due to changes or cuts to benefits. About 17.6% said pupils mainly attend breakfast clubs to socialize. The survey found that teachers believe that offering breakfast to pupils often helps improve their concentration and ability to learn. One primary school teacher said: "Although there is a charge for our breakfast club, we have accessed funding for those pupils on free school meals and the breakfast club had an effect on their attendance, concentration and being in school for the start of lessons. ATL general secretary Dr Roper said a nutritious meal at the start of the day has a huge impact on pupils' ability to learn. "Many schools do everything they can to ensure children eat well during school term-time. But there are many children living in poverty, who we fear won't be getting a decent meal a day in the holidays and this is something the government needs to address," she said. A Department for Education spokesman said: "We know how important it is for children to have a good breakfast. We want schools and local authorities to use their budgets to best meet the needs of their children. Many provide breakfast clubs which offer a free meal to children from poorer families. The Pupil Premium, which will double to PS 2.5 billion in 2014-2015, targets extra money to help schools to provide support such as this to the most disadvantaged children. The free school meal scheme also ensures that these children have access to a nutritious lunch every day. By getting breakfast offered by breakfast clubs, pupils can _ . | [

mmlu_train_20667 | Washington: NASA has announced evidence that Jupiter's largest moon, Ganymede, has a saltwater ocean under its icy surface. The ocean seems to have more water than all the water on Earth's surface, according to new Hubble observation. New Hubble observations of Ganymede's magnetic field strongly suggest that the moon, which is the largest in our whole solar system, is home to a subsurface ocean. Scientists estimate the ocean is 95 kilometres thick, which is about 10 times deeper than Earth's oceans. But unlike our salty waters, Ganymede's ocean is buried under 150 kilometres of ice. While scientists have speculated since 1970s about the presence of an ocean on Ganymede------the largest moon in our solar system------ until now the only observational evidence came from a brief flyby by the Galileo spacecraft, which didn't observe the moon long enough to confirm a liquid ocean. This discovery marks an important milestone, highlighting what only Hubble can accomplish. In its 25 years in orbit, Hubble has made many scientific discoveries in our own solar system. A deep ocean under the icy surface of Ganymede opens up further exciting possibilities for life beyond Earth. Scientists have already confirmed the existence of an ocean on Europa, another moon orbiting Jupiter, and NASA has announced plans to send an unmanned mission there searching for the life that might come with liquid water. Hubble is a telescope that orbits Earth, but because of its impressive gravitational analyses it can be used to study the inside of far distant planets. Using these same principles, scientists could theoretically detect oceans on distant planets as well. What can we learn about the Ganymede from the passage? | [

Do different stars have planets? We can see the planets round our own sun. But we haven't seen any more. The stars are too far away from us. Stars give out light, but the planets don't have any light of their own. So we can't see them. They're too far, and too dark. Still, we can tell that some stars have planets. While a big planet goes round, it pulls its star to one side. And sometimes we can see this, Then we know that the star has a planet. For example, Barnard's Star is a small red star.

mmlu_train_17417 | You may have heard the popular saying, "there are always more fish in the sea". But as many new studies show, fish populations are changing, and not necessarily for the better. Consider the case of big, predatory fish. These giants, like sharks and cod , eat other smaller fish. Big fish are an important part of the marine ecosystem because they keep down the numbers of smaller fish. Without fish that eat other fish, populations of smaller swimmers would increase, eating more plants, and leaving less vegetation for other creatures, including future fish. As fierce as predators can be, they're no match for fishing technology. Many people love to catch predatory fish like sharks, cod and tuna, and new studies suggest that over-fishing is threatening these creatures near the top of the marine food chain. In one study, Villy Christensen and his colleagues looked at 200 past studies of marine life to learn how fish populations have changed over time. Christensen reported that between 1910 and 1970, the numbers of big predators decreased slowly, and that in 1970 their populations really started to drop. Around that time, fishing ships began using new tools that led to more fish being caught. The numbers have been falling quickly ever since. Reg Watson looked at the problem from the perspective of the fishermen. In the middle of the 20thcentury, Watson reported, fishing boats didn't go far from home, and most fish were caught near the shore. That was no longer true by the 1980s. By then, fishing had moved farther from shore, into the open oceans, and was helped by the development of new technologies. But since the 1990s, something has changed. Despite new technologies and more efforts, fishing operations have not continued to develop. Scientists study historical data to understand the present, and this research is needed to forecast the future of fish and fishing. And the forecast doesn't look good: large predator fish are becoming harder to find, and soon may disappear. Which of the following would scientists most probably agree with? | [
"It may soon be difficult to find large predator fish.",
"It will cost much more in the future to catch big fish.",

mmlu_train_71539 | Can you imagine that someone could cure all the diseases in the world? It seems like an impossible job, But Priscilla Chan wants to make it come true. Chan, 31, is from the United States. Many people may know her as a wife of Mark Zuckerberg , the founder of Facebook. But Chan herself has done a lot to help people. Chan and Zuckerberg said in September that they would give out $3 billion , that's about Y=20 billion in the next 10 years to help deal with all of the world's diseases. As a doctor for children, Chan was a big driver in this decision. "By investing in science today, we hope to build a future in which all of our children can live long and meaningful lives," she said. She cares about not only children's health but also their education. Before becoming a doctor, Chan taught science to the 4th and 5th graders at a school in California for a year. That year she started a project called The Primary School. It provides education for children from kindergarten to the 12th grade. Chan herself knows how important education is to a child. She has a Chinese father and a Vietnamese mother. Her parents didn't come to the US with much. But they worked hard to make sure Chan and their other two daughters had the best opportunities possible. Chan went to Harvard University in 2003 and now works as a doctor. "I realized that I was so lucky to be what I was," said Chan. "It drives me to make sure others, no matter what background they have, can have their opportunities, to reach their dreams and their full potential ."

mmlu_train_68975 | If a snake bites you, take a photo with your mobile phone! It save your life. This is the surprising advice of a British cook. One day Henry Jackson was working in a restaurant kitchen. He picked up a dish from a table, and suddenly a snake appeared and bit him on the hand. A few days earlier, the snake came to the restaurant from Asia in a box of bananas. It climbed out of the box and hid under the dish. " I tried to pick it up and it bit me. I threw it away, but it landed in the fridge. So I closed the door." Jackson said. Anyway, Jackson was cool and he took a photo of the snake with his mobile phone. Soon his hand began to ache and he went to hospital. Then his chest began to hurt. Doctors couldn't say what was wrong because they didn't know what kind of snake it was. Then Jackson remembered his mobile phone photo. The doctors sent it to London Zoo. When they knew the kind of snake, they could give Jackson the right medicine, and he left hospital the next day. " So my advice is this: If a snake bits you, pick up your phone. Take its photo first and then call the hospital. Show the photo to the doctors," suggests Mr. Jackson. " Oh, and if the snake doesn't smile for its photo, don't worry!" The text tells us if we are in danger and have a phone with us, it will help us to do _ thing. | [

mmlu_train_17315 | While football fans feel strongly angry and shocked about mistakes made by referees because they cannot see clearly what has happened, a small German company is quietly pleased. For Carlos Technologies, mistakes made by referees are the kind of advertising that money cannot buy. The company has developed a tiny chip that fits inside a football and determines whether the ball has crossed the goal line, by being able to discover its exact location on the field. The world football organization, FIFA, has shown interest in the technology. It is very possible that the new technology will be used in the 2018 World Cup in Russia. "We've been testing the technology at the main soccer stadium in Nuremberg for some time and more recently in an under-17 FIFA Cup in Peru," said Gunter Rohmer, a director of the company. "The technology has performed well, and we're pretty optimistic that it will be used at the games in Russia." The chip only weighs 12 grams, and is placed in the center of the football. It sends 2,000 signals a second to a receiver network of 12 antennas ,placed around the field. The receivers then send information about the ball's location to a central computer, and because it works in real time, it can immediately tell the referee whether a goal has been scored. The chip even can tell when the ball crosses the line in mid-air. Oliver Braun, one of the inventors of the chip, says that feedback from German referees was generally positive. Germany sports-wear giant Adidas is also optimistic about using this kind of chip in other ball sports. FIFA aims to test the technology later this year at another game in Japan before deciding whether or not to introduce it in all 12 stadiums in Russia for next World Cup.

mmlu_train_10382 | It is common for older people to forget things. Now an American study has found that memory starts to fail when we are young adults. People younger than thirty years of age usually do not know that they are starting to forget information. But scientists from the University of Michigan say the loss of memory has usually already started. Researchers say people do not observe this slow reduction in mental ability until the loss affects their everyday activities. Denise Park led the new study. She directs the Centre for Aging and Cognition at the Institute for Social Research at the University of Michigan. Her team studied more than 350 men and women between the ages of twenty and ninety years. The study identified people in their middle twenties with memory problems. She says young adults do not know they are forgetting things because their brains have more information than they need. But she says that people in their twenties and thirties are losing memory at the same rate as people in their sixties and seventies. Ms. Park says people between the ages of sixty and seventy may note the decrease in their mental abilities. They begin to observe that they are having more trouble remembering and learning new information. The study found that older adults are more likely to remember false information as being true. For example, they remembered false medical claims as being true. Younger people remembered hearing the information. But they were more likely to remember that it was false. Ms. Park is now using modern imaging equipment to study what happens in the brains of people of different ages. She is studying what parts of the brain older adults use for different activities compared to younger adults. Ms. Park says mental performance is a direct result of brain activity and brain structure. She says keeping the brain active is important. She hopes future studies will identify ways to improve the operation of our aging minds. Which of the following statements is NOT TRUE? | [

However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment. ks5u Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas. ks5u There are many environment-friendly sport. Power walking is one of them that you could take up today. You don't need any special equipment except a good pair of shoes;and you don't have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control. ks5u Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be "green gyms". They are better replacements for traditional health clubs and modern sports centers.

mmlu_train_55043 | It seems like every day there's some new research about whether our favorite drinks are good for us. One day, science says a glass of red wine a day will help us live longer. The next day, maybe not. It seems journalists are pretty interested in wine research and the same might be said for coffee. Now there's been a lot of research into whether coffee's good for our health "the results have really been mixed",admits Neal Freedman who led the coffee study and published his findings in a medical journal recently. "There's been some evidence that coffee might increase the risk of certain diseases and there's also been maybe more recent evidence that coffee may protect against other diseases as well". Freedman and his colleagues undertook the biggest study yet to look at the relationship between coffee and health. They analyzed data collected from more than 400,000 Americans ages 50 to 70 participating in the study. "We found that the coffee drinkers had a modestly lower risk of death than the non-drinkers, he said. Here's what he means by "modestly": those who drank at least two or three cups a day were about 10 percent or 15 percent less likely to die for any reason during the 13 years of the study when the researchers looked at specific causes of death, coffee drinking appeared to cut the risk of dying from heart disease, lung disease injuries, accidents and infections. Now, Freedman stressed that the study doesn't prove coffee can make people live longer .A study like this can never prove a cause-and-effect relationship. All it can really do is to point researchers in the right direction for further investigation. And even if it turns out that coffee is really good for you, scientists have no idea why.

Scientists have found that if people listen to MP3 players at a very high volume for more than five hours a week, they could lose their hearing in five years. High-volume music can keep people excited, so young people would like to keep their players high. It's too bad for the ears. So the MP3 listeners should keep the player within safe volume levels, no higher than 60~70 of full capacity .

mmlu_train_38682 | 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." Indeed, he adds several cautions about how the findings should be understood. "For one thing, people eat these fats in foods all of the time. That is likely to be a lot more than would be consumed from indoor dust," he said. What's the best title for the text? _ | [

Watch out for walkers and other bicyclists, and always use your lights in dark conditions. Theft Prevention Always securely lock your bicycle to a bicycle rack -- even if you are only away for a minute. Register your bike with the University Department of Public Safety. It's fast, easy, and free. Registration permanently records your serial number, which is useful in the possible recovery of the bike stolen. Equipment Brakes Make sure that they are in good working order and adjusted properly. Helmet A necessity, make sure your helmet meets current safety standards and fits properly. Lights Always have a front headlight -- visible at least 500 feet in front of the bike. A taillight is a good idea. Rules of the Road Riding on Campus As a bicycle rider, you have a responsibility to ride only on streets and posted bicycle paths. Riding on sidewalks or other walkways can lead to a fine. The speed limit for bicycles on campus is 15 mph, unless otherwise posted. Always give the right of way to walkers. If you are involved in an accident, you are required to offer appropriate aid, call the Department of Public Safety and remain at the scene until the officer lets you go.

Hirta has plenty of grass for the sheep to eat, and no natural predators of the sheep live on the island. Some sheep have dark wool, and some have light wool. The sheep with dark wool tend to be much larger and stronger than the sheep with light wool. However, researchers have found that in the last 20 years, the sheep with light wool have increased in number. Usually, strength and size help animals survive and breed.

mmlu_train_30082 | The earth is not the only body that travels around the sun. With it are eight other planets, fellow members of the sun's family. Two of them, Mercury and Venus, are nearer while the other six, namely Mars, Jupiter, Saturn, Uranus, Neptune and Pluto, also in their given order from the sun, are farther from the sun than the earth is. The farther they are, the longer trips they make around the sun. People noticed long ago that these traveling bodies moved around in the sky in definite paths. It is a force called gravity that holds them in their paths. We know that every little bit of matter in the universe pulls upon every other bit of matter. The pull between two bodies is proportional to the product of their masses. Because the sun is so large the pull between the sun and the planets are thus great. If it were not for this pull, the planets would fly off into space. In the same way there exists a pull between the earth and the moon, which keeps the moon traveling in its orbit around our planet, the earth. Gravity holds you to its surface, and pulls back to it the ball which you throw into the air. Of course the ball also pulls on the larger earth but the earth is so much larger that the pull is not noticed. Now remember that large bodies exert a greater pull than smaller ones which contain less material. But each object in the universe, no matter how small, pulls on all other objects to some degree. From the passage we can see _ | [

mmlu_train_62709 | If you're a male and you're reading this, congratulations: you're a survivor. According to statistics, you are more than twice as likely to die of skin cancer as a woman, and nine times more likely to die of AIDS. Assuming you make it to the end of your natural term, about 78 years for men in Australia, you'll die on average five years before a woman. There are many reasons for this--typically, men take more risks than women and are more likely to drink and smoke--but perhaps more importantly, men don't go to the doctor. "Men aren't seeing doctors as often as they should," says Dr. Gullotta. "This is particularly so for the over-40s, when diseases tend to strike." Gullotta says a healthy man should visit the doctor every year or two. For those over 45, it should be at least once a year. Two months ago Gullotta saw a 50-year-old man who had delayed doing anything about his smoker's cough for a year. "When I finally saw him it had already spread and he has since died from lung cancer," he says. "Earlier detection and treatment may not have cured him, but it would have prolonged his life." According to a recent survey, 95% of women aged between 15 and early 40s see a doctor once a year, compared to 70% of men in the same age group. "A lot of men think they're undefeatable," Gullota says. "They only come in when a friend drops dead on the golf course and they think, 'Geez, if it could happen to him, ...'" Then there's the ostrich approach. "Some men are scared of what might be there and would rather not know," says Dr. Ross Cartmill. "Most men get their cars serviced more regularly than they service their bodies," Cartmill says. He believes most diseases that commonly affect men could be addressed by preventive check-ups. Regular check-ups for men would inevitably place strain on the public purse, Cartmill says. "But prevention is cheaper in the long run than having to treat the diseases. Besides, the ultimate cost is far greater: it is called premature death." What does Dr. Ross Cartmill mean by "the ostrich approach" (Line 1, Para.9)? | [

mmlu_train_9203 | Dr. Jack M. Gwaltney, Jr. a professor at the University Of Virginia School Of Medicine infected six student volunteers with virus, the most common cause of colds. A few days later, when they were coughing and sneezing, he gathered 37 more people and divided them into three groups. Group 1 members spent three days and nights in the same room with one of the infected students, separated by a screen so they couldn't touch one another. Group 2 sat around a table while an infected volunteer talked, coughed and sang to them. Group 3 held hands with an infected student for ten seconds, and then touched their own noses or eyes. Although most scientists at the time, the mid-70s, believed colds were spread by virus-laden droplets spread through the air when infected people coughed or sneezed, Gwaltney suspected physical contact might play an important role. Sure enough, of the 15 people who had touched a student volunteer, 11 became infected--compared with only one of those who had been sitting at the table, and none who had spent three days and nights together. "The best evidence we have is that hand-to-hand contact is the most efficient way of transmitting virus," says Gwaltney. The study was one of a series that helped establish Gwaltney's reputation as a leading authority. Dr. Robert Couch says, "It would not be inappropriate to call him Mr. Common Cold." When Gwaltney is asked how close scientists are to finding a cure, he replies: "If you mean 'get rid of', I don't think we're going to be able to do that with cold viruses any time soon. But if you look in the dictionary, you'll see that 'cure' is explained as a successful treatment. And we're not just getting more effective at treating the symptoms --we're getting at the root cause too.

mmlu_train_36135 | Living in the wild can be hard. Finding food and staying safe aren't easy. Each day, animals struggle to survive in their habitats. Not all animals get by on their own. Some animals form a close partnership with other kinds of animals. These pairings are called symbiotic relationships. In a symbiotic relationship, the animals depend on each other. One animal helps the other meet its needs. Sounds good, right? Not always. Some animals are not very kind to their partners. In some cases, one animal meets its needs but hurts its partner. Take ticks, for example. These insects suck blood to live. To get blood, they attach themselves to other kinds of animals. Ticks can pass germs that cause disease instead of helping their hosts. In other relationships, animals don't treat their partners so poorly. Both animals benefit from living with the other animal. Small animals called cleaner shrimps have found a way of helping fish at coral reefs. As their name suggests, the shrimps clean the fish. They hang out at what scientists call a cleaning station. A fish stops by. Then a shrimp climbs onto the fish and even steps into the fish's mouth. The shrimp uses its tiny claws to pick stuff off the fish's body. That can include dead skin, tiny pieces of food, and wee creatures that can hurt the fish. The fish gets a nice cleaning. The shrimp enjoys a tasty meal of fish trash. Small birds called plovers are also in the cleaning business. They have big customers-crocodiles. Crocs have long snouts filled with sharp teeth. Cleaning them is tricky. When a croc opens its mouth, the plover hops right in. The croc does not snap its snout shut.Instead, it lets the plover eat small, harmful animals attached to the crocodile's teeth.

These young people really showed the promise of how rewarding physical activities are! We disabled can - and should be -- as active as anyone else. When we get and stay active, we will feel better, be able to do more, have healthier bodies, and look better. It is a fact that exercise actually produces energy and builds on itself. The more we exercise, the fitter our bodies are, and thus the more energy we have to enjoy recreation and the pleasure of life. Not everyone is cut out to be a competitive athlete, but there are things that we can do to strengthen our physical well-being. Experts recommend that spending as little as 30 minutes each day on physical activities provides benefits including lower risk of heart disease, cancer, high blood pressure, diabetes and other serious diseases. Taking steps to become physically fit does not have to mean acquiring expensive training equipment or a gym membership. Exercise can include simple walking and running, gardening, cleaning the house, swimming, tennis, bicycling (stationary or on the road) and so on. The key is to do it on a regular basis. Healthy lifestyles also require good nutritional habits. When choosing foods, nutritionists advise whole grains, flesh fruits and vegetables, fish, and lean cuts of poultry and meat. The benefits of drinking eight full glasses of water a day are also _ . Water provides the means for nutrients to travel to all our organs, improves skin tone , regulates body temperature and contributes to muscle strength and control, which is confirmed by scientists. Fitness results in completing the tasks of daily living, working a full day, and still having energy to participate in recreational activities. By being fit, you'll find that you enjoy recreational activities even more because you won't be tired or suffer from gore muscles. It is time, folks, to get moving.

mmlu_train_67103 | "China now has 350 million smokers, accounting for one-third of the world total. Chinese smokers now become addicted to nicotine at the age of 19, five years earlier than the average starting age of 24 in 1997," a report said a couple of years ago. Of the 1.1 billion smokers all over the world. more than 800 million are in developing countries. And as the world's largest developing country, China also has the largest number of smokers. Some frightening facts start to appear when we examine who China's smokers are. Of the 350 million addicts, more than 100 million are under the age of 18, while more than 50 percent of male teachers and doctors are smokers. Such a high rate of addicts among male teachers and doctors will certainly have a bad impact on the young generation. Teachers are usually expected to be role models for students who tend to consider whatever they do is right and follow their example. It is very likely that the number of teenage smokers will increase in the near future unless measures are taken to forbid teachers from smoking in front of their students or designate schools as no-smoking zones. What is truly puzzling is why so many doctors smoke. They are aware of the results of the habit, such as high blood pressure and lung cancer. Their example only helps justify the addiction of so many others. If educated people set an example by stopping smoking at least in public places. it would be much easier to drive home the notion that it is uncivilized to smoke in public places. In China, there should also be a national law to ban smoking in public places. These would make a massive contribution to cutting the number of people in China who are smoking themselves into early grave.

mmlu_train_44118 | A new study shows students who write notes by hand during lectures perform better on exams than those who use laptops . Students are increasingly using laptops for note-taking because of speed and legibility . But the research has found laptop users are less able to remember and apply the concepts they have been taught. Researchers performed experiments that aimed to find out whether using a laptop increased the tendency to make notes "mindlessly" by taking down word for word what the professors said. In the first experiment, students were given either a laptop or pen and paper. They listened to the same lectures and were told to use their usual note-taking skills. Thirty minutes after the talk, they were examined on their ability to remember facts and on how well they understood concepts. The researchers found that laptop users took twice as many notes as those who wrote by hand. However, the typists performed worse at remembering and applying the concepts. Both groups scored similarly when it came to memorizing facts. The researchers' report said, "While more notes are beneficial, if the notes are taken mindlessly, as is more likely the case on a laptop, the benefit disappears." In another experiment aimed at testing long-term memory, students took notes as before but were tested a week after the lecture. This time, the students who wrote notes by hand performed significantly better on the exam. These two experiments suggest that handwritten notes are not only better for immediate learning and understanding, but that they also lead to superior revision in the future.

mmlu_train_31195 | Forbes asked a panel of architects and campus designers to nominate their picks for the best-looking campuses in the world. These are their top choices. Kenyon College Gambier, Ohio, US Mike Evans, a principal at Norfolk, Va., design firm Hanbury Evans Wright Vlattas + Company, says to be beautiful a campus must have a "signature campus space as a carrier of the campus brand." At Kenyon College, that space is "Middle Path," a 10-foot-wide footpath that serves as the Gothic hilltop campus' central artery. More than just a trail, it's a village green for the tight-knit campus community. Sergei Lobanov-Rostovsky, who teaches 17th-century poetry at Kenyon, says the college, both isolated and pastoral, is "a small place to think big thoughts." Oxford University Oxford, England Teaching within Oxford's stone walls dates as far back as the 11th century, and the school is considered a paradigm for all college campuses. With its labyrinth of quads, cloisters, and archways, it evokes elegance and tradition at every turn. "Its monastic roots and the spectacular quality of its buildings make it an architectural wonderland," says David Mayernik, associate professor at Notre Dame's School of Architecture. Princeton University Princeton, N.J., US Princeton's style is pure Collegiate Gothic ; most of it executed in gray stone covered in, yes, ivy. As imposing as these old stone structures are, the campus keeps life on a "human scale" by preserving green spaces and walkability.Sinuous footpaths, archways, plazas - all are designed to inspire spontaneous discussion and learning. Scripps College Claremont, Calif., US The total plan of this women's college, founded in the 1920's, has always called for artistic connection between buildings and landscape. Together, architect Gordon Kaufmann, in collaboration with landscape architect Edward Huntsman-Trout, created a distinctively Southern Californian blend of Mission Revival-inspired architecture and landscape, which is lovely, evocative and intact. An expert in deciduous trees, Trout planted rows of liquid amber trees to give the students "a sense of autumn" come fall. He also peppered the campus with tulip trees, sycamores, almond and orange trees, as well as rare shrubs. Stanford University Palo Alto, Calif., US New additions like the Science and Engineering Quad manage to gracefully blend modern and technological elements with the timeless, elegant aesthetics of the campus' early California Mission Revival architecture. The campus also scores big points for its dramatic entrance via Palm Drive, its romantic Spanish red-tile roofs and myriad patches of green. Tsinghua University Beijing, China Forbe's panel of architects says natural setting plays a big part in assessing a campus' beauty. In that regard, this campus is blessed: Founded in 1925, Tsinghua sits on the former site of the Qing Dynasty's royal gardens. Many of Beijing's most notable historical sites, like the Summer Palace, are close by.

Bamboo flooring has become very popular with its rich and beautiful golden earth colors.But it is important to shop around for a good-quality bamboo flooring product that contains no formaldehydes ,which is said to be the best kind of bamboo flooring.Many brands use cheaper bamboo that may contain formaldehydes,and this can cause indoor air pollution problems as certain chemical materials in the bamboo slowly release their pollutants into the air. So,why should we turn to bamboo to save the enviroment?In fact,bamboo cannot save the environment directly,but it is an excellent replacement product for much of the hardwood species of trees that are being harvested in rainforests.Once harvested,if these hardwood trees do grow back,it can take up to 200 years!Rainforests are the lungs of our planet and they make a significant contribution to global oxygen production.

Next to the face, hair is one of the main qualities people look for when they consider a woman's beauty. Whether long or short, curly or straight, hair often gets a lot of attention. Each hair on a person's head grows from a single tube-like hole in the skin called a follicle. People are born with all of the hair follicles they are ever going to have. The average person has about one hundred thousand hair follicles. _ begin to form around the third month of pregnancy. Each hair grows independently of other hairs. There are three periods of hair growth. Not all hairs experience the same period of growth at the same time. The period of active growth is called Anagen. During this period, hair grows at a rate of about three tenths millimeters a day, or one centimeter a month. About 85 percent of hair follicles are going through this process at any given time. This period can last from two to six years. The Catagen period of hair growth comes next. It is then that hair growth begins to slow down. This period usually lasts two or three weeks. Finally, hair growth comes to a complete stop and the hairs begin to fall out. This period is known as Telogen. It affects about 15 percent of all hairs at a time. On average, a person loses between 50 and 100 hairs every day. Since each hair grows at a different rate, this process is overlooked.

What is a hybrid car? Any car that uses two or more sources of power is a hybrid car. Most hybrid cars on the road right now are petrol-electric hybrids. The petrol-electric hybrid car is just what it sounds like -- a cross between a petrol-powered car and an electric car. A gas-powered car has a fuel tank , which supplies petrol to the engine. An electric car, on the other hand, has a set of batteries that provides electricity for the car. To be useful to you or me, a car should be able to run at least 300 miles (483 km) before refueling, be capable of being refueled quickly and easily and fast enough to keep up with the other traffic on the road. A petrol car meets these requirements but produces a large amount of pollution. An electric car, however, produces almost no pollution, but can only go 50 to 100 miles (80 to 161 km) between recharging . And the problem has been that the electric car is very slow and inconvenient to recharge. A petrol-electric car combines the advantages of the two power sources into one system that uses both gas power and electric power. Some experts believe that the hybrid car is "the next generation of smart cars". A hybrid car can go up to 50% further than a traditional car can on the same amount of gas!

mmlu_train_85661 | Dear Grandma, How are you? I hope you are feeling well and your leg is improving. Can you walk a bit now? Is your neighbour, Mrs Lu, bringing you enough books to read? I hope so. You'd love our school library, Grandma. There are so many books on all kinds of subjects. The other day I found a book about engineering. I couldn't really understand it but I hope to learn more about this topic sometime. This term I have three new subject classes, so I think I'll tell you about them. I study biology. It is a very interesting subject. I'm learning all about the human body, where everything is and what it does. Did you know that we have a kissing muscle? It's called 'orbicularis' and it's a circle muscle that closes your mouth and moves your lips forward. I love biology. It's so interesting! Another new subject is religion . I didn't think I would like this one, but actually it is very interesting to hear how different people worship . We are learning about lots of religions from all over the world, not only Asia. My other new subject is Spanish. It's really difficult to learn a new language but I know it will be useful for me in the future, if I want to travel around the world. Spanish is one of the official languages of the European Union and the United Nations. I've learnt that Spanish is not only spoken in Europe but in South America too. Countries like Peru, Bolivia, Chile, and Mexico also speak Spanish. You know I've always wanted to go to Mexico, so if I can speak Spanish it would be really useful. Did you study these subjects when you were at school? I suppose subject choice changes over time, doesn't it? I'll come to visit you again in the next holiday, which I think is in eight weeks' time. I'll bring you some of my new books if you like. I hope you can write back soon and tell me all the village news. I miss you very much.

mmlu_train_66023 | A farm planted levels or floors is called a vertical farm. A skyscraper type building can house a vertical farm. Since the garden is built upwards,rather than outwards,it requires much less space than a conventional farm. The world is quickly running out of room for conventional farming. Vertical farms could be a key to this situation. An 18story vertical farm could feed as many as 50,000 people,all in an area which is the size of the average city block. Vertical farms in the city could cut down on transportation costs as well. Think about the amount of fuel it takes to transport food from farmland to city. The resources saved would be surprising. Besides saving travel time,food would be delivered in fresher condition and with less damage. There is a growing concern about the use of pesticides in agriculture today. But the vertical farm would be a greenhouse type environment, avoiding the need for a large number of pesticides. Vertical farms can be built in a contained space,therefore they are an excellent solution for living well in an environment far different from our own. Hydroponics could be a big part of vertical gardening. This would reduce the amount of soil needed to grow food. Of course,not all food does well with this type of planting,but there are many crops that actually seem to do better. In some climates,a lack of sunlight creates a short growing season. The solar power option may not work as well here. The addition of grow lights would make it possible to grow crops in vertical gardens in these areas .In other words,we could grow crops in areas where we never could before. Vertical farms may just be a concept for now,but they are a concept that will solve many of our problems in the future. It can be learned from the passage that vertical farms _ . | [

mmlu_train_50137 | Because plants cannot move or talk, most people believe that they have no feelings and that they cannot receive signals from outside. However, this may not be completely true. People who studied plants have found out that plants carry a small electrical charge . It is possible to measure this charge with a small piece of equipment called "galvanometer". The galvanometer is placed on a leaf off the plant, and it records any changes in the electrical field of the leaf. Humans have a similar field which can change when we are shocked or frightened. A man called Backster used a galvanometer for his studies of plants and was very surprised at his results. He found that if he had two or more plants in a room and he began to destroy one of them - perhaps by pulling off its leaves or by pulling it out of its pot - then the galvanometer on the leaves of the other plants showed a change in the electrical field. It seemed as if the plants were signalling a feeling of shock. This happened not only when Backster started to destroy plants, but also when he destroyed other living things such as insects . Backster said that the plants also knew if someone had destroyed a living thing some distance away, because they signalled when a man who had just cut down a tree entered the room. Another scientist, named Sauvin, achieved similar results to Backster's. He kept galvanometers fixed to his plants all the time and checked regularly to see what the plants were doing. If he was out of the office, he telephoned to find out about the signals the plants were sending. In this way, he found that the plants were sending out signals at the exact times when he felt strong pleasure or pain. In fact, Sauvin could cause a change in the electrical field of his plants over a distance of a few miles simply by thinking about them. Which of the following is true according to the passage? | [

mmlu_train_48663 | Watching television makes it easier for toddlers to kick and scream, according to a U.S. study. Children under two should not watch any TV. The longer they sit in front of the box, the worse their behavior becomes. Just having the TV on in the background, even if the child wasn't watching it, was also connected to troublemaking behavior although the relationship wasn't as strong, said the researchers. "Parents should be smart about TV use," researcher Jennifer Manganello from the University at Albany, New York, said. "They should limit the time that children use TV, pay attention to the content of TV programs, and consider how TV is used throughout the home." The study looked at 3,128 women from 20 U.S. cities who had a child between 2005 and 2008. While there was some diversity of education among the women, one-third hadn't graduated from high school. Two-thirds of the mothers said their three-year-old watched more than two hours of TV a day, and the average viewing time for children was around three hours. On average, the TV was on for about five additional hours on a common day. After accounting for factors such as living in a violent neighborhood, scientists also found watching TV was strongly connected to behavior such as hitting others, having angry moods, being disobedient , and screaming a lot. The researchers thought that children may see violence on TV, and spend less time on positive development tasks such as reading or playing. The American Academy of Paediatrics suggests no TV at all for children at two and younger, and two hours a day or less for older kids. Children who spend much time watching TV will _ . | [

mmlu_train_8954 | FOR most people, life without plants is unimaginable. They feed us, clean up our air and brighten up our gardens. But what if someone told you that even our smartphones can benefit from plants? Meet the scientists from the Freiburg University of Mining and Technology in Germany. According to reports from Reuters, they have come up with a way to take the important element germanium from plants. The element was first discovered in Germany (hence the name) and was used to develop the first transistor because it can transport electricity very quickly. Nowadays, silicon-germanium alloy plays an important role in making computers, smartphones and fiber-optic cables . Although germanium can be found in soil around the world, it is difficult to extract . In the traditional process, people take the material after zinc mining or burning coal. But the Freiburg scientists decided to fall back on the natural world. Biology professor Hermann Heilmeier is one of the scientists who are using common plants for this uncommon process. "Different energy crops are being planted, for example, sunflowers, corn ... we want to use them for phytomining. In German we call it 'mining with plants'." Others have used this method in the past with metals like gold and copper . But in their study, the Freiburg scientists brought germanium from the soil into the roots and shoots of the plants, harvested them and then took the element from the plants. The process did not cost too much because germanium can be taken after plants are processed for use as biogas . So many of the costs are already covered in existing biogas plants. However, there is still a lot of work to do before we can all experience the benefits. At the moment germanium can only be harvested in very small amounts, just a few milligrams per liter. Now scientists are working on different plants to improve this. "As is so often the case, industry is still waiting because they want to see everything already working. Then they say, 'We'll have it.' But of course we have to complete the step in between first," said Professor Martin Bertau, head of industrial chemistry at Freiburg University. Which of the following statements would Professor Martin Bertau agree with? | [

mmlu_train_33688 | You may complain that there are too many tests on the way to college entrance, but an increasing number of students want to take one more. That is the Scholastic Aptitude Test, or SAT, an American test for students who intend to apply for college admission. Chen Huanlu, aged 18, from Shandong Province took part in the SAT subject tests (SAT 2) in Hong Kong on June 2. She has also been scheduled to take the SAT reasoning test (SAT 1) in October. "I hope to study environmental engineering at an American university, where I may have more opportunities to get cutting-edge knowledge in this area," said Chen. However, not all SAT test takers want to apply to American universities. "I wanted to see how I would do when faced with plenty of stress and also to evaluate my scholastic level by an American standard. The SATs made my school life more diverse," said Senior 2 student Zhou Yuxiang from Sichuan Province. Zhou, aged 17, a top student in his school, was inspired by some of his friends.

mmlu_train_42980 | After a day of work and play, the body needs to rest. Sleep is necessary for good health. During this time, the body recovers from the activities of the previous day. The rest that you get while sleeping enables your body to prepare itself for the next day. There are four levels of sleep, each being a little deeper than the one before. As you sleep, your muscles relax little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts back and forth from one level of sleep to the other. Although your mind slows down, from time to time you will dream. Scientists who study sleep state that when dreaming occurs your eyeballs begin to move quickly (although your eyelids are closed). This stage of sleep is called REM, which stands for rapid eye movement. If you have trouble falling asleep, some people recommend breathing very slowly and very deeply.

The 45-year-old from southern Sweden was found on Friday, February17, too weak to say more than a few words. He was found not far from the city of Umea in the north of Sweden by snowmobilers who thought they had come across a ruined car until they dug their way to a window and saw movement inside. The man, who was lying in the back seat in a sleeping bag, said he had been in the car since December 19. "Just incredible that he's alive considering that he had no food, but also since it's been really cold for some time after Christmas." a rescue team member told regional daily Vasterbottens- Kuriren, which broke the news. Ebbe Nyberg, duty officer at the Umea police, said police saw no reason to doubt that the man had been stuck in the car for a very long time. "We would not make up something like this.

Umea University Hospital, where the man is recovering after being rescued by police and a rescue team, said in a statement he was doing well considering the circumstances.

In African countries, the WHO says the number of over-weight or obese children is twice as high as it was 20 years ago. Around the world, about 43 million children under the age of five were overweight in 2013. Overweight and obese children are more likely to become overweight and obese adults. The condition can _ serious health problems like heart diseases. Francesco Branca is the director of the WHO Department of Nutrition for Health and Development. He says urban lifestyle makes people eat processed food more often ,which has a high sugar ,fat and salt content. He also says people are gaining weight because of their lack of activities. They travel in cars or other vehicles more than on foot. The WHO experts say to lower obesity rates is especially complex in countries that also deal with high rates of infectious diseases. The WHO has some basic solutions for individuals and countries. The organization says you should lower your intake of fat, sugar, salt and processed food and eat more fruits,' vegetables and increase physical activity. The WHO says these actions are especially important for children. And WHO expert Branca says mothers should breastfeed their babies for at least the first six months of life, if possible. More importantly, governments should consider providing vitamins for children and educational campaigns about problems linked to obesity would also help. In his view, government policies should deal with how food is marketed to children and food producers must balance quality and taste with the dangers of sugar, fat and salt.

mmlu_train_55172 | It's time you started eating sensibly. Experts at the first Chinese Students Nutrition and Health Festival in Kunming last week listed eight bad eating habits. *Watching television while having meals or snacks. Doing this means you don't pay attention to your food, forget how full you are, and so overeat. It can also cause digestion diseases. One way to avoid this is only to eat in certain areas of your home. * Replacing meals with snacks. Many students think that eating small snacks can help them diet. But it often results in overeating and health problems related to a lack of vegetables, carbohydrates ,proteins and vitamins. Snacking only works if it is well planned and includes healthy foods such as nuts, vegetables, fruit and yogurt. *Having drinks rather than water. Fizzy drinks and fruit juice are usually high in calories and sugar, which can cause weight problems. Water is important in making your brain cells and every organ in your body work properly. For your body to burn fat, it needs at least eight glasses of pure water a day. Liquids like soda and coffee actually take water away from your body. *Refusing to drink milk. Milk is the best natural food--it provides you with protein, which makes your bones strong and teeth healthy. * Choosing meat and certain vegetables over others. Different foods provide different kinds of nutrition. If you don't have a balanced diet, this can result in malnutrition and a weaker body. *Eating in front of the computer and staying there after meals. Take a walk after eating and it helps your stomach digest the meal. *Buying from roadside snack bars. If you shop at these places, be careful--many are not clean enough. * Eating throat tablets as if they were sweets. If you eat throat tablets when you have no throat disease, they may affect the bacteria in your mouth and cause real throat problems. _ can possibly cause digestion problem. | [

mmlu_train_49214 | A team of researchers from Oxford University has demonstrated a self-driving car that is different from such cars being tested by Audi, Ford, etc. It' s much cheaper because it's based on off-the-shelf technology and controlled by an ordinary iPad. Instead of using GPS to understand the location, the car learns routes when a person is driving, and then asks after it's got it down, if the driver would like the computer to take over. As time passes, it's becoming very clear that people believe computers would be better drivers than humans. This has been proven by extensive research that indicates that computers are able to react more quickly to driving conditions, make smarter decisions, don't take risks, and don't make mistakes in concentration. They don't drink either, of course, which means accidents due to drunk driving could be reduced dramatically if the computer could take over when someone needs to get home from the bar. And the team says drivers don't need their cars to know everything about every road, condition or possible danger. Instead, they just need to know how to get from one point to another, and to do a good job of it when asked. To that end, the researchers have added cameras, lasers, a central computer to process information and a regular iPad. In practice, the car would learn how to get to and from places that the driver frequents, such as their work place, the local pub or grocery store. Once it has it down, the computer asks the driver if they' d like a rest. If so, they simply tap the iPad, and the car takes over. It' s very simple and doesn't require nearly the same number of devices as those being tested by other car companies. The researchers say people might be able to get the total price of the system below a hundred dollars. And of course, the iPad can be lifted out and carried away for other purposes when not being used as a driver assistant. In which column of a newspaper can we find this passage? | [
