mmlu_train_19096 | Is a mouse that can speak acceptable? How about a dog with human hands or feet? Scientists, the people with the know-how to make such things happen, are now thinking about whether such experiments are morally right or not. On Nov. 10, Britain's Academy of Medical Sciences launched a study on the use of animals with human materials in scientific research. The work is expected to take at least a year, but its leaders hope it will lead to guidelines for scientists in Britain and around the world on how far _ can go mixing human genes into animals in search of ways to fight human diseases. "Do these constructs challenge our idea of what it is to be human?" asked Martin Bobrow, a professor of medical genetics at Cambridge University and chair of a 14-member group looking into the issue. "It is important that we consider these questions now so that appropriate boundaries are recognized." Using human material in animals is not new. Scientists have already created monkeys that have a human form of the Huntingdon's gene so they can study how the disease develops; and mice with livers made from human cells are being used to study the effects of new drugs. However, scientists say the technology to put ever greater amounts of human genetic material into animals is spreading quickly around the world --- raising the possibility that some scientists in some places may want to go further than is morally acceptable. Last year in Britain there was a lively debate over new laws allowing the creation of human-animal embryos for experiments. On one side of the debate were religious groups, who claimed that such science interferes with nature. Opposing them were scientists who pointed out that such experiments were vital to research cures for diseases. The experts will publish reports after the end of the study, in which they will give definitions for animal embryos with human genes or cells, look at safety and animal welfare issues, and consider the right legal framework to work within.

mmlu_train_89102 | Penguins live together, but each pair has a little piece of ground of their own. When a penguin wants to walk through its neighbor's ground, it must ask for permission . If it does not, it will have to fight. Penguins come and go all day. They fight for fish and look after their children. All penguins are good parents--the male penguins are perhaps the best parents in the world. They choose their wives in the dark They can only hear them--not see them. Then the female penguins lay their eggs and go away for about two months. The males look after the eggs. If the eggs get cold, there will be no chicks. There is no food. The snow falls and the wind blows--sometimes at 150 kilometers an hour. The penguins do not move. When the females return from the sea, they will not remember their husbands. It doesn't matter. Only one thing-- their eggs. Male penguins never fight--unless a penguin leaves a chick for a minute. Then they fight because they all want it. They are strange and wonderful birds.

mmlu_train_17864 | Most academics would view a post at an elite university like Oxford or Harvard as the crowning achievement of a career--bringing both honour and access to better wine cellars. But scholars desire such places for reasons beyond glory. They believe perching on one of the topmost branches of the academic tree will also improve the quality of their work, by bringing them together with other geniuses with whom they can collaborate and who may help spark new ideas. This sounds reasonable. Unfortunately,as Albert Laszlo Barabasi of Northeastern University,in Boston (and also, it must be said, of Harvard), shows in a study published in Scientific Reports, it is not true. Dr Barabasi and his team examined the careers of physicists who began publishing between 1950 and 1980 and continued to do so for at least 20 years. They ranked the impact of the institutions these people attended by counting the number of citations each institution's papers received within five years of publication. By tracking the association of individual physicists and counting their citations in a similar way, Dr Barabasi was able to work out whether moving from a low to a high-ranking university improved a physicist's impact. In total, he and his team analysed 2,725 careers. They found that, though an average physicist moved once or twice during his career, moving from a low-rank university to an elite one did not increase his scientific impact. Going in the opposite direction, however, did have a small negative influence. The consequence is that elite university do not,at least as far as physicists are concerned,add value to output. That surprising conclusion is one which the authorities in countries such as Britain, who are seeking to concentrate expensive subjects such as physics in fewer, more elite institutions--partly to save money, but also to create what are seen as centers of excellence--might wish to consider. On what basis did Dr Barabasi's research team draw conclusions that getting a post at a higher-rank university won't help scholastic impact? | [

mmlu_train_90539 | An astronaut's work may sound exciting, but living in space isn't as fun as you think. The website www.space.com lists the disadvantages of living in space. Here are some of them. When astronauts work outside the station during spacewalks, they have to wear special gloves. The gloves are very tight. They can hurt the astronauts' fingernails and even make them fall off. In space, you don't have many choices in what you eat. It's hard to get fresh fruits and vegetables. It is not OK to eat bread because it leaves crumbs . Crumbs could fly around everywhere. In space, it is impossible to have a good shower because water can fly all over the ship and break the machines. Astronauts have to use a special water-shooting gun and a washcloth. Astronauts lose their bone strength quickly during their stay in space. So far, there is no way to solve this problem. They do exercise while they're in space to try to keep their bones strong as long as possible. Perhaps the hardest part of life in space is the feeling of loneliness.

mmlu_train_6134 | Too much TV-watching can harm children's ability to learn and even reduce their chances of getting a college degree, new studies suggest in the latest effort to examine the effects of television on children. One of the studies looked at nearly 400 northern California third-graders. Those with TVs in their bedrooms scored about eight points lower on math and language arts tests than children without bedroom TVs. A second study ,looking at nearly 1000 grown-ups in New Zealand, found lower education levels among 26-year -olds who had watched lots of TV during childhood. But the results don't prove that TV is the cause and don't rule out that already poorly motivated youngsters may watch lots of TV. Their study measured the TV habits of 26-year-olds between ages5 and 15. These with college degrees had watched an average of less than two hours of TV per week night during childhood, compared with an average of more than 2 1/2 hours for those who had no education beyond high school. In the California study, children with TVs in their rooms but no computer at home scored the lowest while those with no bedroom TV but who had home computers scored the highest. While this study does not prove that bedroom TV sets caused the lower scores, it adds to accumulating findings that children shouldn't have TVs in their bedrooms What would be the best title for this text? | [

On 17 July, a piece four kilometers wide enters the Earth's atmosphere with a massive explosion. About half of the piece is destroyed, but the remaining part hits the South Atlantic at 200 times the speed of sound. The sea boils and a huge hole is made in the sea bed. Huge waves are created and spread outwards from the hole. The wall of water, a kilometer high, rushes towards southern Africa at 800 kilometers an hour. Cities on the African coast are totally destroyed and millions of people are drowned. Before the waves reach South America, the second piece of the comet lands in Argentina. Earthquakes and volcanoes are set off in the Andes Mountains. The shock waves move north into California and all around the Pacific Ocean. The cities of Los Angeles, San Francisco and Tokyo are completely destroyed by earthquakes. Millions of people in the southern half of the earth are already dead, but the north won't escape for long. Because of the explosions, the sun is hidden by clouds of dust, temperatures around the world fall to almost zero. Crops are ruined. The sun won't be seen again for many years.

mmlu_train_21402 | Girls really prefer pink and boys prefer blue, recent research shows. The reasons could have its origins in the hunt for food on the African savannah thousands of years ago. Evolution may have developed women's preference for pink, perhaps because it helped to find ripe fruit and healthy men with reddish faces, while both men and women have a natural desire for blue, according to scientists at prefix = st1 /NewcastleUniversity. " Everyone in today's western culture, from parents to toy manufactures, seems to assume that little girls like pink." Said Prof. Anya Hulbert, who wanted to find out whether the reason was cultural or to do with biology. A love of salmon, _ and coral does seem to be rooted into females, rather than picked up from their mothers. The participants in the study were Chinese and British. The Chinese students showed a marked preference for red, " Culture may contribute to this natural female preference," said Pro. Hulbert. In her experience, 208 young adult men and women were asked to select, as rapidly as possible, their preferred color1. Hulbert and her colleague Dr. Yazhu Ling marked the results and found that while men preferred blue, women tended to choose pink. Hulbert said she could only prefer about the preference for blue: " Here again, I would favor evolutionary arguments. Going back to our savannah days, we would have a natural preference for a clear blue sky, because it signaled good weather. Clear blue also signals a good water source."

mmlu_train_38756 | Big trees are incredibly important ecologically. For a start, they provide food for countless other species and shelter for many animals. With their tall branches in the sun, they capture vast amounts of energy. This allows them to produce massive crops of fruit and flowers that sustain much of the animal life in the forest. Only a small number of tree species have the genetic ability to grow really big. The biggest are native to North America, but big trees grow all over the globe, from the tropics to the forests of the high latitudes . To achieve giant size, a tree needs three things: the right place to establish its seedling, good growing conditions and lots of time with low adult death rate. Lose any of these, and you will lose your biggest trees. In some parts of the world, populations of big trees are dwindling because their seedlings cannot survive. In southern India, for instance, an aggressive non-native bush, Lantana camara, is invading the floor of many forests. Lantana grows so thickly that young trees often fail to take root. With no young trees to replace them, it is only a matter of time before most of the big trees disappear. Without the right growing conditions, trees cannot get really big and there is some evidence to suggest tree growth could slow in a warmer world, particularly in environments that are already warm. Having worked for decades at La Selva Biological Station in Puerto Viejo de Sarapiqui, Costa Rica, David and Deborah Clark and colleagues have shown that tree growth there declines markedly in warmer years. "During the day, their growth shuts down when it gets too warm, and at night they consume more energy because their metabolic rate increases," explains David Clark. With less energy produced in warmer years and more being consumed just to survive, there is even less energy available for growth. The darks' theory, if correct, means tropical forests would shrink over time. The largest, oldest trees would progressively die off and tend not to be replaced. According to the Clarks, this might cause a destabilization of the climate; as older trees die, forests would release some of their stored carbon into the atmosphere, causing a cycle of further warming, forest shrinkage and carbon emissions. Besides, big trees face threats from elsewhere. All the following factors are a must for making big trees EXCEPT _ . | [

mmlu_train_18585 | For many workers trying to lose weight, the weekend is a chance to do some exercise and eat something healthier than a supermarket sandwich at their desk. But some slimmers take a slightly different approach -- consuming more than half their weekly calorie intake from Friday night to Sunday. Away from the daily routine at work that helps them keep control of what they eat, they are snacking and drinking their way to a shocking 10,000 calories, a survey has found. Almost three-quarters of people trying to lose weight admit to over-eating at the weekend. A meal with friends or family, complete with alcohol, as well as a late-night snack before bed, can lead to adults consuming up to 3,500 calories in one day, a survey found. Men typically need 2,500 calories a day and women 2,000 calories. Consuming this amount would see men and women get through half their weekly calorie intake over the course of a 'bad' weekend. Women were found to eat less on a Sunday because of guilt over their consumption over the previous two days. Men had fewer doubts about a third day of excess. The biggest weekend diet danger comes from snacking between meals, the survey found. Some say they will often spend Saturday night in front of the TV with their families -- combining watching their favorite shows with crisps and biscuits. And seven in ten people admitted to having fattening takeaways at weekends, with pizza the most popular. Alcohol is another big factor in weekend bingeing.Around 70 percent still like to have a roast on a Sunday or a big meal with family or friends and a third of those will have second helpings. A spokesman from Forza Supplements, the diet company that conducted the survey, said, "We all have bad weekends where we have a lot of fun, but dieting goes out of the window."

mmlu_train_44666 | There is a very special wolf that lives in Africa. They are actually called, the African wild dog, of painted dogs. These animals live in open woodlands, or in the plains of Africa. Today, however, most of the animals can be found in eastern or southern Africa. These animals are beautiful. They have rounded ears instead of pointed like most dogs, and they have four toes on each of their four feet, also a unique characteristic because other dogs have five. Their fine fur is always different from each other. The fur is usually a combination of black, brown, red, and white, and sometimes even yellow. No wonder they're called the painted wolf. The African wild dog is a very social animal. They live in groups and have numbers from five to about twenty. The members of a group are always very close to one another. They communicate in their own language or body language. When someone is very old or sick, the others will help, and they are willing to share the food with the elders and with those who are weak, which is what we should learn from. The family does everything together, from raising young, to sleeping together, to hunting. When they hunt, they will work together suing team work to kill animals that are larger than them. They sometimes hunt farm animals. This is unfortunate, because both poachers , and people who own farms shoot the painted dogs who are just trying to survive. Before, there used to be many large groups throughout the land, but now the African wild god is very rare. They are also losing their population because of their own loss of habitat thanks to human's farming and forest cutting. According to the author, what should we learn from African wild dogs? | [

mmlu_train_25779 | Smart Exercise Doctors are starting to find more and more information that suggests a connection between exercise and brain development. Judy Cameron, a scientist at Oregon Health and prefix = st1 /ScienceUniversity, studies brain development. According to her research, it seems that exercise can make blood vessels, including those in the brain, stronger and more fully developed. Dr. Cameron claims this allows people who exercise to concentrate better. As she says: "While we already know that exercise is good for the heart, exercise can literally cause physical changes in the brain." The effects of exercise on brain development can even be seen in babies. Babies who do activities that require a lot of movement and physical activity show greater brain development than babies who are less physically active. With babies, even a little movement can show big results. Margaret Barnes, a pediatrician , believes in the importance of exercise. She thinks that many learning disabilities that children have in elementary school or high school can be traced back to a lack of movement as babies. "Babies need movement that stimulates their five senses. They need to establish a connection between motion and memory. In this way, as they get older, children will begin to associate physical activity with higher learning," says Margaret. Older people can beef uptheir brains as well.CornellUniversitystudied a group of seniors ranging in age from seventy to seventy-nine. Their study showed a short-term memory increase of up to 40 percent after exercising just three hours a week. The exercise does not have to be very difficult, but it does have to increase the heart rate. Also, just like the motion for infants, exercise for older people should involve some complexity. Learning some new skills or motions helps to open up memory paths in the brain that may not have been used for a long time. For most people, any type of physical activity that increases the heart rate is helpful. The main goal is to increase the brain's flow of blood. And your brain can benefit from as little as two to three hours of exercise a week. Margaret Barnes thinks that a lack of movement in infancy can | [

A blog lets you post on the Internet without having to know web design or be technical. You are given an environment to make dated entries on the topic of your choice which are "published", so other people can read them. Authoring a blog, maintaining a blog or adding an article to an existing blog is called "blogging". Blogging has revolutionized Internet publishing in the last several years because it gives everyone with Internet access the opportunity to become an online writer. Objects, such as "text and photos" in a blog can be called "blog posts", "posts", or "entries". The person who posts these entries is called a "blogger". Now, somewhere around the world, a blog is created almost every 6 seconds. Because it's great potential, Bill Gates views it as important as e-mail, BBS, and MSN. He's trying to make blogs the important tools for future business communications. Who is a blogger? | [

mmlu_train_13208 | Their cheery song brightens many a winter's day. But robins are in danger of wearing themselves out by singing too much. Robins are singing all nightas well as during the day, British-based researchers say. David Dominoni, of Glasgow University, said that light from street lamps, takeaway signs and homes is affecting the birds' biological clock, leading to them being wide awake when they should be asleep. Dr Dominoni, who is putting cameras inside nesting boxes to track sleeping patterns, said lack of sleep could put the birds' health at risk. His study shows that when robins are exposed to light at night in the lab, it leads to some genes being active at the wrong time of day. And the more birds are exposed to light, the more active they are at night. He told people at a conference, "There have been a couple of studies suggesting they are increasing their song output at night and during the day they are still singing. Singing is a costly behaviour and it takes energy. So by increasing their song output, there might be some costs of energy." And it is not just robins that are being kept awake by artificial light. Blackoiids and seagulls are also being more nocturnal. Dr Dominoni said, "In Glasgow where I live, gulls are a serious problem. I have people coming to me saying `You are the bird expert. Can you help us kill these gulls?'.During the breeding season, between April and June, they are very active at night and very noisy and people can't sleep." Although Dr Dominoni has only studied light pollution, other research concluded that robins living in noisy cities have started to sing at night to make themselves heard over loud noise. However, some birds thrive in noisy environments. A study from California Polytechnic University found more hummingbirds in areas with heavy industrial machinery. It is thought that they are capitalising on their predators fleeing to quieter areas. What is the researchers' concern over the increase of birds' song output? | [

mmlu_train_38026 | Australia's koalas could be dying out within 30 years, unless urgent measures is taken to stop the losing in population, according to researchers. They say development, climate change and bushfires have all related to reduce the number of wild koalas sharply. The Australian Koala Foundation said a recent survey showed the population could have dropped by more than half in the past six years. Previous estimates put the number of koalas at more than 100,000, but the latest figures suggest there could now be as few as 43,000. The foundation collected field data from 1,800 sites and 80,000 trees to calculate the numbers. In one area in northern Queensland estimated to have 20,000 koalas a decade ago, a team of eight people could not find a single animal in four days of searching. The foundation said besides problems caused by cutting down forests, hotter and drier conditions because of global warming had reduced the nutritional value of their staple food, eucalyptus leaves, leading to poor nutrition for them. Koalas, which live in the forests in Australia's east and south, are very particular about what types of the leaves they eat. Foundation chief Deborah Tabart said: "The koalas are missing everywhere we look. It's really no tree, no me. If you keep cutting down trees you don't have any koalas."She is hoping the new figures will persuade the government's Threatened Species Steering Committee (TSSC) to list the koala as threatened. But committee chairman Bob Beeton said a decision was not likely recently and the koala's status as one of the country's favorite animals would not be a factor. "There's a number of species which are attractive and people have special feelings towards them. We don't consider that," Mr. Beeton was reported as saying by the AFP agency.

mmlu_train_91394 | Some people believe that classes, teachers and school buildings will no longer be necessary in the near future because of the Internet and other new technology. Perhaps this will be true one day, but if the world has no schools, I can't imagine how our society will be. In fact, we should learn how to use new technology to make schools better. We should invent a new kind of school connected to libraries, museums, science centers, labs and even companies. Technological companies should create learning programs for schools. Scientists could give talks through the Internet. TV networks and local stations could develop programs about things students are studying in school. Labs could set up websites to show new technology, so students could see it on the Internet. Is this a dream? No. There have been many cities where this is beginning to happen. Here the whole city is connected to the Internet, and learning can take place at home, at school, and in the office. Businesses provide programs for the schools and the society. The schools provide computer labs for people without their own computers at home. Because everyone can go on the Internet, older people use it as much as younger ones, and everyone can visit faraway libraries and museums as easily as nearby ones. How will this new thing of school change the usual way of learning? It is a little early to be sure, but it is very exciting to think about it.

mmlu_train_17554 | Daniel Hillel developed drip irrigation techniques. The techniques make farming possible in places where there is not enough water. Because of this, he won this year's World Food Prize. Hillel is using the techniques in his orchards near his home in Israel. Irrigating drop by drop -- called drip irrigation -- has changed agriculture by greatly reducing the amount of water needed. Farmers now rely on it in places from Spain, to Africa, to America. "We in California grow about 50 percent of the fruits and vegetables of the continental United States," says Jan Hopmans from University of California at Davis. "And these drip irrigation techniques make it possible." Hillel got his start in dry land farming in Israel's Negev Desert in the 1950s. "The key was making good use of water," he says. "There's much land. Water is limited." These farmers did not have the advantage of running irrigation water through channels to their crops. So Hillel and others gave plants just what they needed and just where they needed it. "The idea is to use water little by little," Hillel says. It worked so well that Hillel was soon traveling around the world, showing others how to do it. Experts say drip irrigation's importance is growing, as climate change and rising population make water supplies become few in many parts of the world. "This is where water use, climate change and crop production all meet at one point," Hillel says. "And this has been really the essence of my career."

mmlu_train_38596 | On the whole, it's not something we parents shout about, but one in four of us does it. Hiring private tutors for our children is now widespread. "It's expensive, but worth it," says Ashan Sabri, whose daughter Zarreen, is having tuition in biology and chemistry in preparation for A-levels this summer. "My husband and I tried to tutor her at home, but we found all our knowledge was out of date and we were only confusing Zarreen. We also tried a group revision course but all the children were sitting in a room for different kinds of exams. On the whole, we think one-to-one tuition works best." The real reason is: does tutoring do any good? "It's not the _ ," says Professor Judith Ireson, author of a 2005 Institute of Education report on the subject. "It's still up to the child to do the learning. If he or she isn't interested, sending them to a private tutor won't do any good. However, we did find that students who had private tuition in mathematics during the two years before GCSE achieved on average just under half a grade higher than students who did not have a tutor." In which case, surely it's time to break open the champagne? Not necessarily, says Elaine Tyrrell, head of The Rowans School, Wimbledon, a preparation school which regularly gets children into the best private schools. "While we recommend private tutoring for a few children whose first language isn't English, we don't encourage it for the others. With the level of education they get here, children really ought to be able to pass the entrance exams without any extra teaching. And our worry is that they might just get used to getting help from last-minute tutoring, but, once they actually get to that school, they won't be able to cope." But Mylene Curtis, owner of Fleet Tutors, one of the biggest tutoring agencies in the country, holds a different view. "In some respects, the hurdles children have to leap in order to get into these schools are set at a higher level than the reality," says Curtis. "We often find that, once a child has got into a school, the standard of work isn't as high as was feared. The trick is to do well enough in the exam to win a place."

mmlu_train_54611 | Many students attend Miami University for its zoology program, hoping to become a doctor someday, but Joseph Frame has come for a different reason -- to become a vet. "Ever since I was a little boy, I've been interested in animals," Frame said, "but when I grow up, I realized that I didn't want to just take care of dogs and cats. I wanted to work with animals you wouldn't find in your house." Before coming to Miami, Frame worked with his vet Dr. Reid. He learned about the details of being a vet from him. Working with small animals, Frame observed many procedures there. Frame also worked with another vet at Oxford University during his first year at Miami, which involved a leadership position. "I'm in charge of a high school kid," Fram said, "He sometimes needs to be motivated. I like his support system." To realize his goal, Frame began working at the Wilds in Cumberland, Ohio after he met Reid. The Wilds is a non-profit conservation center and is the home for rare and endangered animals. The Wilds combines the concepts of conservation science and education programs to mainly children. After his first year at Miami, Frame began to educate children about the animals. "I think teaching children is an enjoyable experience, especially when they're really interested in animals," Frame said. Frame also explained if a vet school didn't work out, he would be interested in working in animal education. "I would at least have a Zoology degree," Frame said, "The wilds is connected to many zoos all over the country, so I'm sure I can find a job in education." For now, Frame plans to continue working at the wilds this coming summer with a new job at hand, which involves teaching the public about the endangered animals they are protecting and doing shows with owls. While Frame is still an undergraduate student at Miami, he continues his passion for animals. Becoming an exotic vet may be a few years down the road, but Frame continues to work had for this dream, hoping it will become a great reality. Why did Joseph Frame work with Dr. Reid? | [

mmlu_train_16509 | As the nights get lounger, those who suffer from the winter blues will be planning ways to escape to the sunshine. But there may be a much simpler way of cheering yourself up... simply shining a bright light into your ear canal. Up to one in four Britons suffer from seasonal affective disorder, with seven per cent of the population having full-blown SAD. It is caused by the brain not receiving enough daylight which is needed to trigger serotonin , a hormone that regulates mood. Symptoms range from mild lethargy to depression and insomnia, but a cure might be in sight. Two clinical trials, run by Valkee - who make a device that can shine light into your ear - and the University of Oulu in Finland, have found that carefully targeted light can help prevent the condition. Juuso Nissila, Valkee's co-founder and chief scientist said: "We presented earlier that the human brain is sensitive to light". "These two clinical trials demonstrate that channeling bright light via ear canal into brain's photosensitive areas effectively prevents and treats seasonal affective disorder." The University of Oulu reported that in their first study, 92 per cent of the patients with seasonal affective disorder achieved full remission after a month of daily eight-to-12 minute doses of light from the Valkee. Time Takala, chief physician at the Oulu Deaconess Institute said: "These two trials show that bright light channeled into the brain via ear canal is an important future method to treat seasonal affective disorder." Valkee launched its bright light headset in August 2010. It is classed as a medical device under EU regulations. The device channels bright light direct to the brain via the ear canal to prevent and cure depression, mood swings and even circadian-rhythm disorders such as jet lag. It costs PS185 and looks like an iPod - only the earphones emit light rather than sound. It can be inferred from the passage that _ . | [

The most common leaked password in 2014 was "123456," followed by "password" -- both topped the list the year before, too. While numbers were as popular as ever as passwords, sports terms like "baseball" and "football" were used more often. Birthday years were common too (especially 1989, 1990, 1991 and 1992) and names like "Michael", "Jennifer" and "Hunter" are also among the top 100 worst passwords of 2014.

It's now recommended to pick a different password for each account you use -- you wouldn't use the same key in all of your locks, and the same goes for passwords. Companies like Facebook, Twitter and Apple are now trying to make hacking more difficult on their services by offering two-factor authentication , which is basically like double locking your door at night.

The parents of Tim Berners-Lee both worked on one of the earliest commercial computers and talked about their work at home. As a child he would build models of computers from packing material. After graduating from Oxford University he went on to the real thing. In the 1980s, scientists were already communicating using a primitive version of e-mail. While working at a laboratory in Switzerland, Tim Berners-Lee wrote a program, which let him store these messages. This gave him another idea: write a program that will let academics from across the world share information on a single place. In 1990 he wrote the HTTP and HTML programs which form the basis of the World Wide Web. The next year his programs were placed on to the Internet. Everyone was welcome to use them and improve them if they could. Programmers used this codes to work with different operating systems. New things like web browsers and search engines were developed. Between 1991 and 1994 the number of web pages rose from 10 to 100,000. In 1994 Tim Berners-Lee formed the newly formed World Wide Web consortium , or W3C. More than 200 leading companies and laboratories are represented by W3C. Together they make sure that everyone can share equally on the web. "The Web can help people to understand the way that others live and love. It helps us understand the humanity of people." he says. Scientists began to communicate using e-mail . | [

They believe that their living environment may be changing. Now, the US government is stepping in to help fight this problem. President Barack Obama has asked for $50 million(310 million yuan ) in his 2015 budget to fight this problem, and has announced the start of the Pollinator Health Task Force. This group will work on keeping the US bee population healthy and strong, and will show people what they can do to help bees. Even though many people may not like bees, they are an important part of how we grow food. As pollinators , they move from one plant to another. Through pollination, plants can grow seeds and fruit. It's said that at least 90 kinds of plants including nuts, fruits and vegetables depend on bees for pollination. The new Pollinator Health Task Force will work hard to protect bees, and build new hives for pollinators. It also plans to start a public education activity to make more people know the importance of pollinators, and actions that can be taken to protect them.

When successful matching is being experienced, our questioning of the text continues at the unconscious level. Different people converse with the text differently. Some stay very close to the words on the pages; others take off imaginatively from the words, interpreting, criticizing, analyzing and examining. The former represents a kind of comprehension which is written in the text. The latter represents higher levels of comprehension. The balance between these is important, especially for the advanced readers. There is another conversation which from our point of view is equally important, and that has nothing to do with what is read but with how it is read. We call this a "process" conversation as opposed to "content" conversation. It is concerned not with meaning but with the strategies we employ in reading. If we are advanced reader our ability to hold a content conversation with text is usually well developed but not so our ability to hold a process conversation. It is just this kind of conversation that is of importance when we are seeking to develop our reading to meet the new demands being placed upon us by studying at a higher level.

mmlu_train_35784 | Hemophilia results when a gene fails to produce the protein needed for the blood to clot ,or change from a liquid to a solid .The fault gene is passed from parents to children .People with hemophilia suffer uncontrolled bleeding .This can result in pain , tissue swelling and permanent damage to joints and muscles. One in every ten thousand males has the most common kind of hemophilia .It is extremely rare for females to have it. Patients can be treated with the missing clotting substance .They generally can lead normal lives. Scientists say gene treatment may be a possible way to cure hemophilia in the future .Researchers consider hemophilia the best disease for gene treatment because it is caused by a single fault gene .Also ,only a small increase in the missing clotting substance could provide good results .They tested gene treatment in six patients with severe hemophilia. First ,they removed skin cells from the patients' arms .The researchers grew the cells in the laboratory .They added copies of the needed gene taken from healthy people .Then they created hundreds of millions of genetically changed cells .They placed these cells into the patients' stomachs.After four months ,the amount of blood clotting substance in the blood increased in four of the six patients .Some of the patients reported a decrease in bleeding problems .However ,ten months later ,the clotting substance was no longer in the patients' blood .It is not clear if the implanted cells died or the added genes stopped working.

mmlu_train_30067 | Last March, the H7N9 virus hit Shanghai, Anhui, Jiangsu, Zhejiang and so on. It seemed that most people who were infected with H7N9 had the common flu . Some people suffered from a fever or a cough. Don't be afraid--it's not easy to be infected with the virus. Here is some advice to help you protect yourself when it comes. Wash your hands. You need to wash your hands with soap and hot water before you eat, after you use the toilet, and after you touch animals, because your hands may carry viruses. Cover your nose and mouth. When someone sneezes or coughs, flu viruses can travel as far as one meter through the air, so you'd better stand a proper distance while talking to someone who has a cold. And always cover your mouth and nose with a piece of paper when you sneeze or cough, and then clean your hands. Wear a mask . Some doctors say that masks can stop the flu as much as 80%, but if you don't wash your hands often, it's no use wearing a mask. And it's necessary to wear the mask in the groups of people. Do sports often. Exercises will help make your body strong enough to resist the virus. How many ways to stop the virus are mentioned in the passage? | [

In one study, hospital patients with a view of trees had shorter hospital stays and less need for pain medications. Another study indicated that prisoners with a view of the outdoors had fewer doctor visits. "Why do we desire nature? Maybe we're programmed to need it, since our ancestors' survival was so dependent on their connection with nature," suggests biologist E.O. Wilson. Want to find out if contact with nature improves your outlook on life? Try a few of these ideas. Hang out a bird feeder and watch the birds that visit it. Sit down in the backyard or a nearby park. Close your eyes. What do you hear? Birds singing? The wind in the trees? Crickets chirping? Find an anthill. Sit down and watch the ants work. Take a walk right after a rainstorm. What looks different? Smells different? Go barefoot on a sandy beach. Open the curtains and the window, if the weather allows it. On a windy day, watch the trees.

The Skinny Player features flexible speakers allowing the user to enjoy music conveniently. When it gets dirty, the user can simply clean it using a damp cloth. No batteries either.

Of course, neither of them could really do that for you-you would just "borrow" their voices. AT & T labs will start selling speech software that it says is so good at reproducing the sounds of a human voice that it can recreate voices and even bring the voices of long-dead famous people back to life. The software, which turns printed text into speech, makes it possible for a company to use recordings of a person's voice to say things that the person never actually said. Possible customers for the software, which is priced in the thousands of dollars, include telephone call centers, companies that make software that reads digital files aloud, and makers of automated voice devices . The advances raise several problems. Who, for example, owns the rights to a famous person's voice? (Some experts even believe that new contracts will be drawn that include voice-licensing clauses.)

mmlu_train_57917 | Nuclear radiation has a certain mystery, partly because it cannot be detected by human senses. It can't be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around but we can't detect them or sense them without a radio receiver. Similarly, we can't sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things. At very high levels, radiation can kill an animal or human being outright by killing masses of cells in important organs. Even the lowest levels can do serious damage. There is no level of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be serious. This is the case when only a few cells are hit, and when they are killed outright. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They reproduce themselves in an unusual way. They can grow into cancer. Sometimes this does not show up for many years. This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the knowledge of the person at the time that damage has occurred. A person can be irradiated and feel fine, then die of cancer five, ten, or twenty years later as a result. A child can be born weak or easy to get serious illness as a result of radiation absorbed by its grandparents. Radiation can lead to serious trouble even at the lowest level _ . | [

mmlu_train_8169 | It is reported that conservation groups in North America have been arguing about the benefits and dangers of wolves. Some groups believe wolves should be killed. Other people believe wolves must be protected so that they will not disappear from the wilderness For Killing Wolves In Alaska,the wolf almost disappeared a few years ago,because hunters were killing hundreds of them for sport. However.1aws were established to protect the wolves from sportsmen and people who catch the animals for their fur.So the wolf population has greatly increased. Now there are so many wolves that they are destroying their own food supply. A wolf naturally eats animals in the deer family. People in the wilderness also hunt deer for food.Many of the animals have been destroyed by the very cold winters recently and by changes in the wilderness plant life.When the deer can't find enough food,they die. If the wolves continue to kill large numbers of deer,their prey will disappear some day.And the wolves will.too.So we must change the cycle of life in the wilderness to balance the ecology.If we killed more wolves,we would save them and their prey from dying out.We'd also save some farm animals. In another northern state,wolves attack cows and chickens for food.Farmers want the government to send biologists to study the problem.They believe it necessary to kill wolves in some areas and to protect them in places where there is a small wolf population. Against Killing Wolves If you had lived long ago,you would have heard many different stories about the dangerous wolf.According to most stories,hungry wolves often kill people for food.Even today,the stories of the "big bad wolf'"will not disappear. But the fact is wolves are afraid of people.and they seldom travel in areas where there is a human smell.When wolves eat other animals,they usually kill the very young.or the sick and injured .The strongest survive .No kind of animal would have survived through the centuries if the weak members had lived.And has always been a law of nature. Although some people say it is good sense to kill wolves,we say it is nonsense! Researchers have found wolves and their prey living in balance.The wolves keep the deer population from becoming too large, and that keeps a balance in the wilderness plant life. The real problem is that the areas where wolves can live are being used by people.Even if wilderness land is not used directly for human needs.the wolves can't always find enough food .So they travel to the nearest source, which is often a farm.Then there is danger.The "big bad wolf" has arrived!

Scientists are now perfecting a way to recharge electrical equipment while on the move. Researchers from theprefix = st1 /Netherlands,FranceandPortugalannounced last week that they have developed very thin solar panels that can be put on clothes. They can also be added to furniture and rooftops. They change light from the sun into electricity. In about three years, you'll be able to wear a jacket that will recharge your phone as you walk. For camping fans, the development could lead to a tent which charges batteries all day so you can have light or music at night. The basic technology of wearable solar panels is the same as that used for traditional solar panels. Pairs of sheets of semi-conducting silicon are linked together to form the panel. But scientists made them much thinner by using different silicon. At one micrometre, they are of the same thickness as photographic film. "This technology will make it easier for people to use clean energy sources," said a physicist in theNetherlandswho led the team of scientists. But the thin panels are not as efficient as the thicker ones. While some solar panels now operate at an efficiency of about 20 per cent, the new flexible panels are only 7 per cent efficient. But the thinner panel is cheaper. An A4 sized panel put onto the back of a jacket cost less than US$13. It could charge a cellphone during a summer walk in the countryside.

The answer is easy. There are exactly hundreds of kinds of cold viruses there. You never know which one you will get, so there isn't a cure for each one. When a virus attacks your body, the body works hard to get rid of it. Blood rushes to your nose and brings congestion with it .You feel terrible because you can't breathe well, but your body is actually "eating" the virus. Your temperature rises and you get a fever, but the heat of your body is killing the virus. You also have a running nose to stop the virus from getting to your cells. You may feel miserable, but actually your wonderful body is doing everything it can to kill the cold. Different people have different remedies for colds. In the United States and sane other countries, for example, people might eat chicken soup to feel better. Some people take hot baths and drink warm liquids. Other people take medicine to stop the fever, congestion, and running nose. There is one interesting thing to note - some scientists say taking medicines when you have a cold is actually bad for you.

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

In middleincome countries, people are gaining weight as they eat fewer fruits and vegetables and more of the cheaper but less nutritious foods. The report also shows that farmers in poorer countries will be leading efforts to feed an expected 9,000,000,000 people by 2050.The outlook predicts that farmers in Latin America,the Caribbean and subSaharan Africa will drive agricultural production in the future. Angel Gurria,SecretaryGeneral of the OECD,said:"We can feed 9,000,000,000 people by 2050 on this planet. But we have to organize ourselves better." But there are plenty of challenges.Onefourth of all agricultural land is damaged. Many countries face water shortages .And experts believe climate change is driving increasingly unusual weather patterns. The report says farmers need to use more growing methods that can't cause damage to the environment.At the same time,it says governments should end economically harmful supports and spend more money to increase agricultural production.Mr.Gurria says rich and poor nations need to treat agriculture more like a business. "In many cases,agriculture is related in people's minds to the poorest. It's related to aid. It's related to very poor living conditions,etc. We have got to shake that image away,"he said.

mmlu_train_10676 | "Lizzie, there's a letter for you!" Emily called up the stairs to her sister. Elizabeth looked down. "Is it from Harvard? They refused my application once." Emily answered, "No, it's from Yale." Quickly, Elizabeth walked downstairs. She took the letter and opened it. "Rejected again," Elizabeth said unhappily. "Who says women can't be doctors?" "They are fools not to accept you. You can't let them stop you, Lizzie," Emily said. "I won't. I'll apply to Geneva Medical College," Elizabeth told her sister. As it turned out, the professors at Geneva Medical College were not fools. They allowed Elizabeth Blackwell to study medicine. In 1848, a year before Elizabeth would graduate, a typhoid epidemic broke out in New York. Elizabeth wrote to Emily. "There's an outbreak of typhoid, and I am going to help. It is dangerous, so if I should not survive, please do me the honor of studying medicine yourself." Emily replied, "Encouraged by your dream and success, I have decided to study in medical school, as well." Having survived the disease, Elizabeth tried to set up a private medical practice. "I graduated first in my class but no one believes a woman can be a good doctor," she said to Emily one day. "All I hear is that doctors should be men, while women should stay home to cook and clean." Emily said worriedly, "I will graduate in June with my medical degree. What shall we do?" Elizabeth thought for a while and replied, "There's a big house in the poor part of our town. We can practice medicine there for people who couldn't afford care." Soon with the help of some friends, Elizabeth and Emily bought the house and opened a hospital for poor women and children. "We'll have an all-women staff ," Elizabeth said. "And later, we'll add a medical college for women!" Emily added. At last, Elizabeth realized her dream of being a doctor. In 1848, Elizabeth wrote to Emily to _ . | [
