mmlu_train_47826 | Preventing obesity and smoking can save lives, but it doesn't save money, reported researchers. "It was a small surprise, for it is against the common belief," said Pieter Van Baal, who led the study. "But it makes sense. If you live longer, then you cost the health system more." The researchers found that from age 20 to 56, obese people racked up the most expensive health costs. But on average, healthy people lived 84 years. Smokers lived about 77 years, and obese people lived about 80 years. Smokers and obese people tended to have more heart disease than healthy people. Therefore in the long run, the thin and healthy group cost about $417, 000, from age 20 on. Smokers cost about $326, 000 and obese people $371, 000. "The result throws a bucket of cold water onto the idea, based on guesswork, that obesity is going to cost trillions of dollars," said Patrick Basham, a professor of health politics. "If we're going to worry about the future of obesity, we should stop worrying about its financial impact," he said. "The benefits of obesity prevention may not be seen immediately in terms of cost saving in tomorrow's budget, but there are long-term gains," said Van Baal. "These are often immeasurable when it comes to people living longer and healthier lives." In the meanwhile, he said that governments should recognize that successful smoking and obesity prevention programs mean that people will have a longer chance of dying of something more expensive later in life. "Lung cancer is a cheap disease to treat because people don't survive very long. But if they are old enough to get Alzheimer's one day, they may survive longer and cost more. We are not advising that governments stop trying to prevent obesity," Van Baal said. "But they should do it for the right reasons." Among middle-aged people, who may cost the health system most? | [

mmlu_train_35926 | In China, more and more middle school students are getting shorter sleeping time than before. Most students sleep less than nine hours every night, because they have much homework to do. Some homework is given by their teachers, and some by their parents. Also, some students don't know how to save time. They are not careful enough while they do their homework, so it takes them a lot of time. Some students spend too much time watching TV or playing computer games. They stay up very late. Some students have to get up early every morning on weekdays to go to school in time by bus or by bike. It may be a long way from home to school. Schools and parents should cut down some of the homework so that our children can enjoy more than nine hours of sleep every night for their health. For children, we should make best use of our time.

mmlu_train_23347 | In today's congratulatory phone call to the team behind NASA's Mars Curiosity rover , President Barack Obama made sure that if the mission discovers Martians, he'll be one of the first to know. "If in fact you do make contact with Martians, please let me know right away," Obama said during the call, "I've got a lot of things on my plate, but I expect that that will go to the top of the list. Even if they're just microbes , it will be pretty exciting." Obama also said he was impressed by the attention that's been paid to flight director Bobak Ferdowsi, the "Mohawk Guy" whose star-spangled haircut and warmhearted behavior during Curiosity's Aug. 5 landing won him Internet fame. "I, in the past, thought about getting a Mohawk myself," Obama joked. "But my team keeps on discouraging me. And now that he's received marriage proposals and thousands of new Twitter followers, I think I'm going to go back to my team and see if it makes sense." The congratulatory phone call is a tradition for the White House. But it was clear that Obama particularly enjoyed congratulating the scientists and engineers behind the amazingly successful landing of NASA's newest Mars exploration. He also said the achievement reflected the American spirit, and he gave his personal promise to protect these critical investments in science and technology. "This is the kind of thing that inspires kids across the country," he said. "They're telling their moms and dads they want to be part of a Mars mission, maybe even the first person to walk on Mars. And that kind of inspiration is the byproduct of work of the sort that you guys have done." The Curiosity rover's $2.5 billion mission focuses on studying billions of years' worth of geology on Mars and determining whether the planet was ever potentially suitable for people to live in. The mission is not specifically designed to explore life, even on the range of microbes, but it could point the way for future life-exploration experiments.

mmlu_train_50589 | Still waiting for little green men to make contact? _ . A leading astronomer has concluded there probably aren't any aliens out there - meaning we are absolutely alone in the universe. Even though there may be tens of thousands of other distant planets similar in size to Earth, the conditions on them are likely to be too hard to support life-forms such as ET. Dr Howard Smith, a senior astrophysicist at Harvard University, believes there is very little hope of discovering aliens and, even if we did, it would be almost impossible to make contact. So far astronomers have discovered a total of 500 planets in distant solar systems - known as extrasolar systems - although they believe billions of others exist. But Dr Smith points out that many of these planets are either too close to the sun or too far away, meaning their surface temperatures are so bad that they could not support life. Others have unusual orbits which cause vast temperature variations, making it impossible for water to exist - the most important thing for life. Dr Smith said, "We have found that most other planets and solar systems are wildly different from our own. It means it is highly unlikely there are any planets with intelligent life close enough for us to make contact." But his suggestions contradict other leading scientists who have claimed aliens almost certainly exist. Only last month Professor Stephen Hawking said the fact that there are billions of galaxies out there made it reasonable to think there were other life-forms in the universe. Researchers from the University of London have recently suggested that aliens could be living on as many as 40,000 other planets. But Dr Smith said: "Any hope of contact has to be limited to a relatively tiny space around the Earth, reaching maybe 1,250 light years out from our planet, where aliens might be able to pick up our signals or send us their own. But communicating would still take decades or centuries." By saying "don't hold your breath", the author advised the reader not to _ . | [

mmlu_train_31419 | A food additive is any substance that is added to food. Many people are put off by the idea of "chemicals in food". The truth is that all food is made up of chemicals. Natural substances like milk, as well as man-made ones like drinks on sale in the market, can be described by chemical formulas . Some chemical substances are indeed harmful, but a person who refused to consume any chemicals would find nothing to eat. The things we eat can be divided into natural and man-made substances. Some people feel that only natural foods are healthy and that all man-made ingredients are to be avoided. But many natural chemicals, found in plants and animals, are harmful when eaten, and some laboratory----made substances increase the nutritional value of food.Other chemicals have natural and man-made forms that are exactly alike: vitamin C is vitamin C, whether it comes from a test tube or from an orange.Like "chemical", "man-made" doesn't necessarily mean "not fit to eat". Food additives are used for many reasons. We add sugar and salt and other things to foods we prepare at home to make them taste better. Food producers have developed a range of additives that stabilize, thicken, harden, keep dry, keep wet, keep firm, or improve the appearance of their products. Additives can make food more convenient or nutritious, give it a longer shelf life, and make it more attractive to the consumer, thus increasing the sales and profits of the producers. Food additives are presently the centre of a storm of serious argument. Food producers have been known to use additives that have not been proved safe; some substances in common use have been proved unsafe and have been taken off the market. Many people feel there's a risk of eating food to which anything has been added. But food additives are now regulated by the FDA of the federal government, and new additives are subjected to strict testing before they can be placed on the market. For most people, the chances of developing serious side effects from the long-term use of presently approved food additives are very slim. From the passage we can learn that _ . | [

mmlu_train_8718 | A British dog-lover has invented a high-tech way of feeding his pet by Twitter( ,). Computer expert Nat Morris ,30, has designed a system to give his pet a "tweet treat" by sending him a Twitter message. His dog Toby gets some delicious dog biscuits from a computer-controlled food machine whenever Nat sends a message to "@ feedtoby". Nat often works away from home and isn't always able to feed Toby by hand. But his new invention allows Nat to feed his dog from anywhere in the world. Nat said, "Toby ly loves it. At first he didn't know what was going on. Now he sits underneath the machine, wagging his tail and waiting for the food to drop." Nat fills the food machine with small pieces of dog biscuits, but not too many in case four-year-old Toby gets too many messages. And Nat has even equipped his house with an online camera so he can see Toby enjoying the food at his home. But one problem is that friends and family have been so amazed with the "tweet treat" machine that they have started sending tweets to Toby too. So Nat has had to restrict feeding time to make sure Toby doesn't turn into Tubby. "People have been sending him tweets at all hours of the day, so I had to limit it to between 9a.m. and 9 p.m. . I'm thinking of doing an updated one which can measure his weight before he is fed, just to make sure he's not putting on too much puppy fat," explained Nat. How Nat's Twitter Feeder works: When a message is sent to @ feedtoby, it is received by a mini -computer that is linked to the feed machine. When the mini-computer receives the message, a bell rings and Toby comes running over and sits in front of the feeding machine. Next, the machine's motor pulls open a trap door which releases a serving of food. The doggy biscuits then drop into Toby's food bowl. Finally a digital camera takes a photo of him and sends it back to Nat on Twitter -- so he knows Toby has been fed. Nat has invented a high-tech way to feed his dog because he _ . | [

mmlu_train_35078 | Scientists have always been interested in the high level of organization in ant societies. American researchers have watched ants build life-saving rafts to keep afloat during floods. They also have documented how ant colonies choose their next queen--the female whose job is to produce eggs rather than seek food for others. New technology is helping to improve researchers' understanding of the insects. But there is still a lot to be learned. Fire ants living in Brazilian forests are perfectly at home in an environment where flooding is common. To save themselves, the insects connect their legs together and create floating rafts. Some ant rafts can be up to 20 centimeters wide. David Hu who is a mechanical engineer with the Georgia Institute of Technology, also known as Georgia Tech, says, "If you have 100 ants, which means 600 legs, 99 percent of those legs will be connected to a neighbor. So they're very, very good at maintaining this network." David Hu and other Georgia Tech researchers want to study ants and the secret of their engineering. They freeze ant rafts and then look at them with the help of computed technology, or CT, images. The pictures show that larger ants serve in central positions to which smaller ants hold. The larger ants form pockets of air that keep the insects afloat. Scientists say small robots or materials that can change shape could be programmed in a similar way, working towards a shared goal. Researchers at North Carolina State University are also studying ants. They examined how Indian jumping ants choose the leader of the colony when they lose their top female or queen.

mmlu_train_16428 | Fish species are expected to shrink in size by up to 24% because of global warming, say scientists. The scientists argue that failure to control greenhouse gas emissions will have a greater effect on marine ecosystems than previously thought. Previous research has suggested that changing ocean temperatures would affect both the distribution and the reproductive abilities of many species of fish. This new work suggests that fish size would also be heavily affected. The researchers built a model to see how fish would react to lower levels of oxygen in the water. As ocean temperatures increase, so do the body temperatures of fish. But, according to lead author, Dr William Cheung, from the University of British Columbia, the lower level of oxygen in the water is key. Warmer waters could decrease ocean oxygen levels and greatly reduce fish body weight. On the other hand, rising temperatures directly increase the metabolic rate of the fish's body function. This leads to an increase in oxygen demand for normal body activities. So the fish will run out of oxygen for growth at a smaller body size. The research team also used its model to predict fish movements as a result of warming waters. The group believes that most fish populations will move towards the Earth's poles at a rate of up to 35km per decade. "So in, say, the North Sea," says Dr Cheung," one would expect to see more smaller-body fish from tropical waters in the future." Taking these factors into consideration, the research team concludes that fish body size will shrink between 14% and 24%, with the largest decreases in the Indian and Atlantic oceans. When compared with actual observations of fish sizes, the model seems to _ what's actually happening in the seas. The researchers looked at two case studies involving North Atlantic cod and haddock. They found that recorded data on these fish showed greater decreases in body size than the models had predicted. Dr Alan Baudron, from the University of Aberdeen, UK, believes smaller-sized fish could seriously affect the ability of fish to reproduce. "Smaller fish produce fewer and smaller eggs which could affect the reproductive potential of fish stocks," he said. What's the main idea of the passage? | [

mmlu_train_42594 | The Nobel Prizes in physiology or medicine, physics and chemistry are the most respected prizes in science. But talk to scientists in private, and many will complain why (besides jealousy, perhaps) are some scientists unhappy with the Nobels? One reason is that the committees can often be slow to recognize achievement. Alfred Nobel specified in his will that the prizes should reward work done in the previous year. But experience soon showed that this was risky, as medals were given out for discoveries that later proved questionable. So a degree of caution is probably advisable. Sometimes, though, it can lead to strange results. Subrahmanyan Chandrasekhar, for instance, had to wait until 1983 to win a prize for work he had done in the 1930s on the structure of stars. However, Albert Einstein never won a prize for his theory of relativity. Even though some pretty suggestive evidence had been produced by Arthur Eddington in 1919, relativity, which has later passed every experimental test ever thrown at it, was still considered somewhat risky and obscure. Another criticism concerns the tradition that no more than three people can share a prize. Science is rarely this clear-cut. Take this year's physics prize, which recognised Peter Higgs for predicting the existence of the mass-bestowing particle that now bears his name. Dr Higgs was only one of several people with a claim. Two other teams---- Rober Brout and Francois Englert, as well as Gerald Guralnik, Carl Hageh and Tom Kibble----- submitted papers on the same idea to the same journal that published Dr Higgs's work, all within a few months of each other. Science often works like this, with different people coming up with similar ideas at similar times. In the event, the committee decided to honour Dr Engler (Brout is dead, therefore unqualified), whose paper was earlier than Dr Higgs's but did not explicitly predict a particle, over Dr Guralnik and his collaborators, who were more comprehensive but published a few weeks later. Who was it that received the Nobel Prize for physics this year? | [

His hiccups began one Sunday lunch time and continued day and night for two weeks. After the first week, Harry's parents took him to hospital, but it took another week for the doctors to cure his attack. Harry, who is now back at school, described what happened to him. "When I began to hiccup, I drank a glass of water but that didn't do any good. That evening I had hiccups every four seconds. We tried everything to stop them. I held my breath and drank cold drinks. My father even tried to give me a shock but that didn't work either." After a week of sleepless nights, he went to hospital. The doctors took an X-ray of his chest but they couldn't find anything wrong.

"We had a hard time calming down students who were shocked at the suicides," said Zhang Jingyuan, head of HUST's center for research and guidance for students' development. "Media coverage may arouse some students' negative emotions again. Suicide can be contagious ," Zhang said. The university reacted promptly to the first suicide on October 23. Advisors and class leaders conducted dorm-to-dorm checks to find students suffering depression. Then psychologists offered one-on-one counseling to them. Notice boards publicizing tips for identifying peers' mental problems and offering help were set up in front of dorm buildings. Leaflets carrying similar information were handed out to each dorm. However, the second suicide came seven days later. Both students were described as men of few words. Their schoolmates didn't see anything to indicate suicide. Zhang revealed that the two students had been bothered by mental disorders. But the school didn't know this until the students' close friends outside school and their parents unveiled the truth after the suicides. According to Zhang, there are only three full-time counselors working in the university's counseling center for its 60,000 students. He complained: "It's unrealistic to rely only on counselors to detect students' mental problems." Some universities in the US may be able to offer solutions to Zhang's worries. They have established programs to train students to be the bridge between troubled friends and counselors. At Worcester Polytechnic Institute, at Worcester, Massachusetts, US, young people in the Student Support Network role play to learn how to detect SOS signals from their schoolmates. They also practice how to gently persuade emotionally troubled students to go for professional help. To develop such empathy , many universities in China have organized campus events to popularize knowledge about mental health. But these are not that attractive to students. Ke Juanjuan, 24, is pursuing a master's degree in English translation at HUST. Ke has found that few of her peers will pay attention to activities about mental health when they are not troubled by it. Rather than bombard students with the words "mental health", Ke suggested the school organize lectures and workshops concerning study, job-hunting and relationships. She explained: "Students care about these topics. They tend to have problems in these areas and may thus get stuck in depression. "By helping students better deal with these problems, the school can effectively prevent self-inflicted injury and suicide among students." Effective prevention comes from long-term education for life instead of temporary intervention to meet an emergency, said Hu Yi'an. Hu delivers a course of lectures on life and death at Guangzhou University. He worries that universities have paid little attention to education for life. "Education for life helps students respect and love life so they won't resort to ending their lives when they have difficulties," said Hu. According to Hu, the principles can be incorporated into everyday teaching. Which one of the following sentences is NOT true? | [

mmlu_train_42570 | Women turn to online shopping Women have jumped ahead of men for the first time in using the Internet to do their holiday shopping, according to a study published last week in the US. For years men have been more likely to shop on the Internet than women, but during the 2004 holiday season, 58 percent of those making online purchases were women. "It shows how mainstream the Internet is becoming," said Lee Rainie, director of the Pew Internet and American Life Project group, which carried out the study. Rainie said it was only a matter of time before women shoppers caught up with men. This is because women traditionally make decisions about spending. Users were more likely to shop online to save time. Internet users between the ages 18 and 29 were responsible for some of the most dramatic increase in the online gift-buying population this time around. However, three- quarters of the US Internet users did not buy holiday gifts online in 2004. They worried about credit card security, or just compared online prices with off-line prices, then dashed off to the shops to get the best deals. " But even if shoppers don't buy online , websites are becoming promotion tools for stores," said Dan Hess, vice president of ComScore Networks Inc. Hess said that actually most stores' websites can make customers fully believe the security of their credit card numbers. And most are able to ensure that gifts arrive on time. " It's all about making the shopping experience more efficient, more reliable and more comfortable." Hess said. What can we know from the passage? | [

mmlu_train_36979 | A recent survey by the Royal College of Nursing (RCN) found that about a third of nurses inprefix = st1 /UKplanned to give up their jobs in the next two years because of the amount of worries and unhappiness with their pay. Among those under 40, the percentage of nurses planning to leave their employers increased from 32% in 2005 to 36% in 2007. The survey also found that 71% of nurses believed they could be paid more for less effort if they left nursing, compared to 60% in 1997. The research was published as the RCN hosted a meeting for nurse leaders to deal with the growing concerns of the nurses. Josie Irwin, an RCN expert, said, " Many nurses say that changes in junior doctors' hours have resulted in an increase in their workload. Nurses are under more and more pressure." Ms Irwin added, "Only 22% of all nurses disagree that they are under too much pressure." She also said that 27% of nurses had a second job, with the main reason that they needed some extra income. "Nurses have made it clear that while they enjoy their work, they have more to do than ever and are not being paid enough to do it." She added. " For this reason, the RCN is calling for a pay increase for nurses to bring their pay into line with others." The survey of 4,795 nurses found that some important changes to the profession had taken place in recent years. The average age of the nurses questioned was 42 ---compared to an average of 33 in 1987. The RCN said that the age increase was because people were now becoming nurses later. In the 1960s, the average age of a nurse on the completion of training was 21, but over the last 5 years it has been an average of 29. Which of the following is TRUEaccording to the passage? | [

On the Internet there are many powerful computers called "servers" to help people send and receive emails. The sending and receiving servers are just like post offices. If you want to use the email service, you have to open at least an email account called a "mailbox", just like we set up a mailbox in a post office. Some mailboxes are provided free of charge by ISPs, which you can get when you open an Internet account. Most widely used mailboxes are provided free by the ISPs, and anyone can apply for one even if he has no ISP account. How to apply for a free mailbox? First you have to connect to the Internet and go to the homepage of the ISP providing free mailboxes. Then you'll find an icon showing "apply for a free mailbox", click the icon, an agreement about the rules for using the free mailbox will appear. If you want to go on, click the icon "I agree". Then you have to fill in a form about your basic personal information, and the name and pin of the mailbox. The pin is the key to the mailbox. After finishing these, you'll get a mailbox like this: your name @ mail server, for example: jack@ 163. com. The mailbox is separated into two parts by a separator "@", which is read as "at". The former part is the name of the mailbox. The latter is the domain name of the mail server. All mails to you will be received by the server and put into your mailbox. You can read this mail on any computer in the world as long as you have the name and pin of the mailbox. If you want to send or receive an email, you should first _ . | [

Even with parents and doctors working together without schools' help, it is very hard to get rid of the disability. Sadly, even today, there are many schools that don't know how to deal with the children with these disabilities. Fairfield Primary School is a good place for children that have been diagnosed with ADHD. The teachers really care about all of their students and they are willing to work with parents and doctors in order to help these children.

mmlu_train_44213 | This is the SCIENCE IN THE NEWS, I'm Barbara Klein. Animal experts say one of the world's most beautiful and rare kinds of big cat is close to disappearing from the wild. A study earlier this year found that about thirty Amur leopards still live free. The cats are also called Far Eastern leopards. Recently, their number has been reduced by one, Some person shot a female Amur, then beat her to death. The animal's body was discovered last month in the Barsovy National Wildlife Refuge in eastern Russia. An official of the World Wildlife Fund, Darron, said this was the third such killing in the area in the past fives years. Mr, Collins said the death of even one adult female is a huge loss for the endangered cat, He noted that the killing reduces the possibility for cubs or young. It is not clear how many Amur leopards still live free. One population count was performed in February and March. Wildlife expert Dmitry Pikuuov led this study. It found evidence of seven to nine males. The study identified three to seven females without cubs, Four leopards were identified as females with cubs. In all, five or six cubs were recorded, Six to eight animals could not be identified. Most of the land where the Amur leopard once lived was in China.New roads and climate change there threatened the animals. So did hunters who kill big cats for their body parts. Mr. Pikuuov says adult Amurs need about five hundred square kilometers with good forests to survive. He said they also need a large and continuing supply of animals like deer for food. He believes the answer to saving the Amur leopard is for governments to provide protected spaces for wildlife. According to the experts the Amur leopards _ . | [

So Leon's father, Paul, created a prosthesis ,using a 3D printer. Now Leon has fingers that open and close."It was a do-it-yourself, father and son adventure," says raw. When Leon was a baby, his doctor advised his parents not to give him a prosthetic hand until he was in his early teens. "The doctor said Leon should first learn to get full use out of the hand he was born with," says Paul. As Leon got older, his father looked into buying a prosthetic hand, which can cost as much as $30,000. Paul found a more affordable solution. One day, Paul discovered a video on the Internet about Robohand, a prosthesis created with a 3Dprinter. He downloaded the free instructions and called Robohand's creators for advice. They told him all he needed was a 3D printerwhich costs around $2,000- and some materials. Luckily, Leon's school had recently purchased a 3D printer and it offered to help Paul build the hand for Leon."We used a soccer shin guard ,cardboard, and tape. They cost about$10," says Paul.

mmlu_train_28210 | When was the last time your family sat down together to have a dinner? The speed at which we live today no longer allows for slow eating habits. Most people work long hours. There is lots of fast food and eating out is now on the increase. Often, food is eaten in front of the television in silence, or a child eats alone in front of the computer. When I was a child, every evening around the same time, one of the children would be asked to set the table, and then we'd go and wash our hands: before the meal. This was the time of day when we would talk about our day at school. But now things have changed a lot. A family environment plays an important role for children in learning to communicate with others and understanding table manners, such as waiting for others to finish before leaving the table and not speaking with a mouth full of food. Parents' likes and dislikes of a certain food will also influence a child's own likes and dislikes. Studies have shown that children who often eat with their families have better results at school than children who eat with their families less than twice a week. Regular meal times give children the chance to discuss their problems with family members. They can also learn to respect others around the table. Talking to your children over dinner is the best way of having their-trust. Children learn good eating habits from their parents at a very young age. Family meals are important.

In the past, women all over the world had to fight to get the same chance as men in education and jobs. Many people said that women should not receive much education because they would not do as well as men when they went to work. One woman who showed that women should have the same chance was Marie, a scientist. In the 1800s scientists knew that a metal, uranium, gave off radiation. They also knew how much radiation came from his element. But they didn't know what this radiation was like; they wondered why and how uranium gave off radiation. Marie Curie set out to answer these questions. In one of her experiments she was studying a certain material which, she knew, contained uranium, But it gave off 4 times as much radiation as usually does. What could explain this fact? Marie Curie thought that there must be another source of radiation in this material. In 1898 Marie Curie set out to find out this new source of radiation, which she named "radium". Her husband, who was also a scientist, helped her. They set up a laboratory in an old building behind a school. For four years Curies searched, doing many experiments, And one morning in 1902 Marie found the source of the radiation. Marie Curie proved to the world that there was element that gave off radiation. And she also proved to the world that, if women are given truly equal chance, they can really help society.

mmlu_train_47256 | Across countryside, non-food crops are growing alongside wheat.Some are used in new alternatives to plastics and other materials, but others will simply be burned. Burning crops is becoming more popular because it is good for the planet.Doing so is also cheaper than burning fossil fuels.As more land is devoted to non-food crop production, the economics of crops for fuel are likely to become even more favorable. Humans have been burning such biomass--organic materials from plants or animals-- since they discovered fire.But that burning fossil fuels could have catastrophic consequences has brought biomass back into fashion. Even allowing for emissions of carbon dioxide from fuel used in planting, harvesting, processing and transporting biomass fuel, replacing fossil fuel with biomass can typically reduce greenhouse gas emissions by more than 90 percent. Power stations around the world are experimenting with forms of biomass to add to their coal or oil, with encouraging results.Indeed, power companies could profit by turning to biomass, especially when the subsidies many governments offer for using renewable energy are taken into account. Farmers can benefit from growing biomass.In Europe, the reduction of subsidies for certain crops is exposing farmers to market forces.Instead of being paid for whatever they produce, farmers must seek a clear demand for their product.Many believe that the demand for alternatives to fossil fuels could be just such a driver. But while biomass offers a variety of potential alternatives, the world's infrastructure has developed around burning fossil fuels to such a stage that switching to biomass involves a change in conception that many companies have not accepted. Also, there are problems with using biomass.Although most coal-fired power stations could take a small amount of their fuel from biomass without significant adjustment, few are built to run on biomass alone.Burning some forms of biomass also causes environmental problems.Oils and waste can be smelly, while wood produces smoke unless burned properly. The supply chains for fossil fuels are set up well, but those for biomass are just the beginning. Sources of supply for biomass rely on farm production and can therefore be less reliable. They are necessarily limited and it wouldn't make sense to turn a very large amount of valuable agricultural land away from food crops.But as the world adjusts to the need to control greenhouse gas emissions, these problems may receive more attention. What do we know about biomass? | [

For many years, Bonestell had been creating beautifully detailed paintings of the Moon and planets. Viewers of his artwork were unhappy because the real Moon did not look like Bonestell's pictures of it. As a space artist, Bonestell tried to make his drawings look exciting and as true as the Moon is. He worked closely with astronomers and scientists to get the most up-to-date scientific information available. But in the 1940s and 1950s, no one had ever seen another planet up close. Yet Bonestell's paintings looked so real that some people thought they were photographs. Even though Bonestell was interested in astronomy, he did not start out as a space artist. As a young man he studied architecture -- the art and science of designing and making buildings. In 1938 Bonestell became a special effects artist in Hollywood. It was here that he learned he could improve his paintings by following the methods used in the movies. In 1944, a popular magazine published a series of Bonestell's paintings of the planet Saturn. He drew Saturn as if it were seen by someone standing on each of the planet's moons. The results were _ . Within a few years, Bonestell's artwork was appearing regularly in magazines and books on astronomy and space flight. Many of Bonestell's artworks had been right all along. But the biggest surprise was the Moon. Someone asked Bonestell what he was thinking when he saw the first pictures from the Moon. "I thought how wrong I was!" he said. "My mountains were sharp , and they aren't on the Moon." But he shouldn't have felt bad. No space artist had ever before taken so many people to so many faraway worlds.

U.S. biochemist Ben Yu has created 'Sprayable Energy,' which claims to be the world's first caffeine - based topical energy spray. He said tired workers can spray a 'shot' of caffeine onto their skin without experiencing a strong buzz, loading up on unnecessary calories or being stuck with a nasty aftertaste like they might get from drinking energy drinks or coffee. The patent-pending caffeine spray is an odourless liquid that is absorbed through the skin and distributed through the body over a number of hours to deliver a caffeine hit that apparently lasts longer than guzzling a cup of coffee. Each small aluminum bottle of Sprayable Energy contains around 160 sprays - the equivalent amount of caffeine to 40 cups of coffee and the creators say it is a much cheaper way of getting a caffeine fix than popping to a cafe. The only active ingredient in the spray is caffeine, which can naturally enter the human body through the skin by passing through cell membranes as it is very similar to nicotine in structure. Each spritz of Sprayable Energy contains around a quarter of the amount of caffeine found in a cup of coffee, but apparently has the same effect as a full cup. The website said: 'The reason for this is our product not being ingested, isn't almost entirely metabolised by the liver before entering your system and becoming available to your body.''Thus, a smaller amount of caffeine can have just the same effect as a very large amount of caffeine ingested through an energy drink or cup of coffee. Sprayable Energy`s website recommends that users apply the spray in places where they normally spritz perfume, such as the neck or wrists, but warns users not to exceed 20 sprays a day. It claims that after spraying the product on the skin, users will feel 'awake and focused without being over-stimulated', which is common with coffee and energy drinks. We can conclude from the passage that _ | [
"Sprayable Energy can not be permitted to be used by people now.",

When people think about carrots, they usually think they are a kind of long, thin, orange-colored vegetable. In fact, carrots are in many different sizes and shapes. And not all carrots are orange. Carrots should be grown in a field that does not have water for a long time. The earth also should not be too hard. To prepare your carrot garden, dig up the earth and turn it over . Weather, soil condition , and time affect the taste of carrots. Warm days and cool nights are the best time to grow great delicious carrots. The best way to decide if a carrot is ready to be harvested is by its color. Usually, the brighter the color is, the better the taste is. Most people do not know that carrots can be grown during the winter months. If the winter is not cold enough to freeze the ground, you can grow carrots the same way as you do during the summer months. Carrots are prepared and eaten in many different ways. They are cut into thin pieces and cooked with other vegetables or meat. Or, they are washed, and eaten just as they come out of the ground. _ carrots have a better taste. | [

More and more children are becoming overweight and growing less creative because they spend too much time in front of the computer according to a survey. Last week Child Protective Services in America organized an activity. The aim of the activity was to encourage children to do some outdoor activities instead of playing computer games at home. Many American children spend about 1,000 hours a year playing computer games -- more time than they spend in school. As a result, they are overweight. Some of them have very poor _ , and they can't see clearly. Everyone should pay attention to his health and try to keep healthy. The doctor says that the longer children play computer games, the more overweight they may become. And the junk food children eat while they're playing computer games makes the weight problem more serious. To keep fit, children need to take exercise regularly, play outside with friends, and explore the world around them. Can you spend two weeks without playing computer games?

"If your computer is down, just write me out a ticket." "I can't write you, out a ticket. The computer is the only one allowed to do so:" I looked down on the computer and every passenger was just star, ding there, drinking coffee and staring at the black screen.

mmlu_train_8181 | Music lessons may improve memory and learning ability in your children by promoting different patterns of brain development, a study shows. After a year of musical training, children aged between 4 and 6 performed better at a standard memory test than did children who were not taught music.The findings suggest that music could be useful for building the learning capacity of your minds. Earlier studies have shown that older children given music lessons become better at IQ tests than those who are musically untrained, but this is the first to show such a benefit in children so young. Professor Laurek Trainor, of McMaster University in Hamilton, Ontario, also found clear differences in the ways in which children's brains responded to sound after a year of musical training.'This is the first study to show that brain responses in young, musically trained and untrained children change differently over the course of a year," she said."These changes are likely to be related to the cognitive( )benefit that is seen with musical training." Professor Trainer's team looked at 12 children, 6 of whom had just started extra-curricular music lessons and 6 of whom were not being taught any music except that included as a standard part of their school curriculum . During the year all 12 children had their brains examined four times using magneto-encephalography (MEG), and each child was played two types of sound --white noise and a violin tone.The MEG measurements showed that all children responded more to violin sounds than to white noise, reflecting a preferable for meaningful tones, and their response times fell over the course of the year as their brains matured.

mmlu_train_27793 | We live in a sweet world. The average American kid consumes more than 20 teaspoons of sugar per day, and adults eat 50% more sugar today than they did in the 1970s. We all know that too much sugar isn't good for you. But did we know it could be dangerous? A team of researchers at the University of Utah used mice to conduct a study on the negative effects of sugar. They found it could have serious effects on people's health. Sugar is found not only in sweets and candies, but also in many household items like pasta and crackers. During the 58-week-long study, mice were fed a diet containing 25% more sugar. This percentage equals a healthy human diet along with three cans of soda daily. The team found that these mice were twice as likely to die as mice fed a similar diet without the sugar. Though the mice did not show signs of obesity or high blood pressure, male mice were 26% less territorial and produced 25% fewer offspring than the other mice. Scientists often use mice for research because they have a similar genetic structure to humans. "Since most substances that are dangerous in mice are also dangerous in people, it's likely that those physical problems that cause those mice to have increased deaths also work in people," says study author James Ruff of the University of Utah. Findings from this study reveal negative effects that are not as noticeable as weight gain or heart problems. Sugar can contribute to long-term changes in the body that can change development and even shorten lives. Cutting sugar out of the American diet altogether may be difficult. But making the effort to control our nation's sugar desire will provide for a truly sweeter future. From the passage we can infer _ | [

mmlu_train_23468 | Albert Einstein died long ago. However, a group of researchers have created a robot which looks like the great scientist. The robotic Einstein is very special because the researchers at the University of California, San Diego (UCSD) have taught their realistic robot to smile, frown and make other complex facial expressions. Scientists believe that babies learn to control their bodies through movements, including learning to speak. "We use the same idea to work out the problem of how a robot could learn to make realistic facial expressions," said Javier Movellan, director of UCSD's machine Feeling Lab. ks5u The San Diego researchers directed the Einstein robot's head to turn in all directions. The robot could see its expressions in a mirror and then use the software to provide data for machine-learning to match facial expressions to the movements of its small motors. Once the robot learned the relationship between facial expressions and the muscle movements, it learned to make facial expressions. Its head has about 30 facial feelings, and each is moved by a tiny motor connected to ht e skin by s sting. Although we've never met Albert Einstein, we have a feeling that the new robot isn't exactly a fair representation of now of the best minds of the 20th century. The figure does not have the grace of the great man, but it can recognize human expressions and react to them in the right way. In fact, if you smile at it, it will smile right back to you.

mmlu_train_52904 | More and more Americans are showing an interest in healthy and locally-produced food. As the interest increases, raising chickens has been gaining popularity in some American cities. "Look, we get three eggs this time." Collecting eggs is a daily pleasure for the Hurst family. Naomi Hurst says her family started to raise chickens in back of their home in Maryland a month ago. "We have wanted to try having backyard chickens for a couple years now. And really just didn't have the time to build my own coop(;) and look out where to buy chickens. And then we met Rent a Coop," said Naomi Hurst. Rent a Coop is a chicken rental business. Tyler Phillips launched the company with a partner 18 months ago. It comes with a mobile coop on wheels, two egg-laying hens, feed, bedding, water bowl, feed bowl, and our 24-hour chicken hotline. You can call with any questions. The price is 185 dollars for four weeks. After the four weeks passed, individuals can extend the rental agreement, return everything or purchase the animals and supplies. Tyler Phillips designs and makes the coops. He says he wants to do as little damage as possible to the environment. "We always try to have as many recycled materials as possible. And I want the coops to be safe for kids. I want the chickens to be comfortable and they have access to the grass while being inside the coop. I want it to be easily movable, light weight," he said. Some cities require people have large pieces of land, if they want to raise farm animals. Others require an agreement with neighbors, limit the number of chickens, or, even ban the birds. Tyler Phillips expects that would change as interest in small poultry coops grows. "I see cities around the D. C. area changing laws almost monthly and different cities will change the law to being prochicken . That is happening all around the United States," he said, He believes that there will be chicken rental businesses in most American cities within five years.

The wave length of each light is different, so the quantity of heat in each light is also different. Flowers, especially their petals ( ) , are easy to be harmed by high temperature. Black flowers can take in all the light waves which cause the flowers to dry up in a high temperature. So black flowers can rarely survive sunlight.

mmlu_train_62155 | Some English words are made up of the same part and have different beginnings and different endings, such as import, export, report and transport. All these words, you can see, have the same "port", which comes from the Latin word, meaning "to carry" or "to move" from one place to another. And according to the bit at the beginning, which we call the prefix, the meaning changes. "Import" means "to carry in" or "to bring into a country"; "export", "ex" means "out of", so this word means "to carry out of the country"; "re" means "back", so the "report" means "to tell somebody, to bring back information to somebody"; "transport", "trans" means "across" and it means "to carry across one place to another". Let's look at the following words: supporter, reporter, importer and exporter. You can see that in this case these words are nouns which are made up of the verbs plus a suffix, thus meaning a person who does this thing. So "supporter" means somebody who supports.

"When we were planning our wedding, I wanted to have these big discussions at 8 a. m.,when I had been up for two hours and was fresh, but Jim would just be getting out of bed," says the 46-year-old designer from Melrose, Mass. "We ended up getting into many arguments because I thought he had no interest, when really he was just still half-asleep." The couple learned to work around their differences over the years, but their situation isn't uncommon, says Katherine Sharkey, professor at BrownUniversity. "More women tend to be larks, while men are like night owls ," she says. The question is:Why? The answer lies in each person's body clock. "The body clock is about 24 hours, thanks to Earth's 24-hour light-dark cycle," Sharkey says. "But some people have a longer natural cycle, and some are shorter." If yours is on the long side, you're more likely to be a night owl. If it runs short, you're probably an early riser. But your body clock can change over your lifetime. There's a developmental piece-school-age children are generally early birds, while teenagers tend to be night owls, and then as they age, adults gradually turn back into morning people," Sharkey says. Besides the clear problems with being a night owl if you have fl day job, "night owls tend to be more low-spirited, and have a higher dependence on coffee," Sharkey says. But the news isn't all bad. A recent study in Belgium found that night owls can stay more focused as the day goes on, compared with early risers. Morning people, however, also have advantages. "Larks generally sleep better, have more regular sleep, and have more flexible characters," Sharkey says. They also tend to be happier and feel healthier than night owls, according to a recent study from the University of Toronto. What is the purpose of the text? | [
