mmlu_train_18349 | More and more mainland high school graduates are considering attending universities in Hong Kong. They feel that attractive scholarships, the high quality of education and a chance to experience a different culture present a good opportunity. At Fudan University's prefix = st1 /Handancampus, nearly 800 local high school graduates have attended an admission interview for Hong Kong University (HKU). The candidates have already passed the national college entrance exam and an HKU written test. HKU applicants in the mainland are 10,000 students this year, more than doubling last year's applicants. "Most of the applicants are excellent high school graduates with outstanding performance in the national college entrance exam," Cui Jijia, an official with HKU's Shanghaioffice, said. Excellent freshmen from the mainland will be awarded a scholarship ranging from HK$30,000 (US$3,862) to HK$100,000 this year, as HKU has set aside a total scholarship budget of HK$55 million for first-year students. One HKU applicant says that entering a university in Hong Kong provides access to jobs in Hong Kong in the future. "I'll choose HKU if I receive an offer from both a local school and HKU," he says. Besides HKU, some other universities from Hong Kong also hold admission interviews for students from mainland high schools. They expect to enroll more than 1,300 mainland students.

mmlu_train_12677 | There are two kinds of changeschemical change and physical change. In a chemical change, there is always a new substance formed. Breaking up water into hydrogen and oxygen is a chemical change. In each of the chemical change at least one new substance is formed. A change is not a chemical change if it doesn't form a new substance. Physical changes are very common, too. There are many examples. You can make a physical change by tearing a piece of paper into two, or by cutting a piece of iron with lathe . Here paper is still paper, and the iron is still iron. Another way of making physical change is dissolving something in water. When you dissolve salt in water, the salt disappears. You may think that a new substance has been formed. But really there is no new substance. The salt is still salt. You can still taste it. So the dissolving of anything is a physical change. When water freezes, the change is also a physical one. The water changes from liquid to solid, but it is still the same substance. That is why the freezing of anything is a physical change. We can separate a chemical change from a physical one by _ . | [

mmlu_train_86759 | Nowadays, many children spend hours a day looking at computer screens or other digital products. Some eye care doctors say all the screen time has caused more children to have what they call computer vision syndrome . Nathan Warford is an optometrist in the US. He says he has seen more children having eye problems. "More children come into my office because their parents have noticed that they have headaches or red eyes, or because their degree of short-sightedness appears to be increasing very fast and they're worried," he said. Dr. Warford says part of the problem is that even if their eyes start to feel uncomfortable or they start to get a headache, some children don't tell their parents, because they don't want their games or the computer to be taken away. Another part of the problem is that people blink less often when they look at the screen.A person who uses a computer or a digital product blinks about a third as much as we normally do in everyday life. If eyes can't stay wet or are too tired, they will not be protected like normal. People blink about _ as they normally do when they use computers. | [

mmlu_train_17032 | In the Pacific Northwest there is a kind of owl that serves as a unique piece to the Northwest habitat -- the northern spotted owl. Northern spotted owls are known to be curious. When seeing you, these owls will come down close and check you out. The northern spotted owl has been a savior of old-growth forests. Old-growth forests are forests that have been around for a long time without significant disturbances. One way the spotted owl has become a protector of old-growth forests is simply by being there. The northern spotted owl has become endangered, and so to protect them from dying out, the government has to protect their habitat. So now any destruction of old-growth forests is illegal. Another way the owls help their habitat is by eating small animals. This helps create a balance in the forest. So, if the northern spotted owl is in a habitat that is protected by laws, why are they still endangered? Unfortunately, a cousin of the northern spotted owl has moved into its neighborhood. The bigger, more aggressive "barred owl" has grown in population and due to loss of the forests they lived in on the East Coast of the United States, they have begun to move to the west coast. These owls are taking the food source and pushing northern spotted owls out of their own home. Although the barred owl is able to live in different habitats, the northern spotted owl can only live in old-growth forests. Many government officials have been at a loss to find an answer to the difficult question, "What do we do with the non-native barred owls?" Some methods include shooting them. It is a difficult problem to deal with. Can you think of any possible solutions? The northern spotted owl _ . | [

mmlu_train_26606 | My friend Jennie gave her bone marrow( )to a 50-year-old woman, a woman she has never met. At the end of March, the Red Cross called back. Six different blood elements were tested ; Jennie matched five completely and was about a 3/4 match of the six. So she was the best match. In April, Jennie went for a complete physical exam by one of the doctors who would perform the surgery. The doctor had to make sure that it would be no tread to her. The doctor told her that the surgery would need to have two quarts of bone marrow from her hip bones. Jennie would probably be released the same day the surgery took place and should expect to be painful for a couple of months. "I didn't think it was that big a deal until I realized I was a match," Jennie said. "There was not a question in my head. It didn't seem like something that was going above and beyond. " Jennie was left with two very small scars on her lower back from the surgery and was giving medication to help reduce the pain. She still felt a great deal of pressure on her lower back. "Being only 21, I felt like I am not old enough to significantly impact someone's life," Jennie said. " It seems strange to me that I could possibly save this woman's life which was being cut short by cancer. " Three weeks after the surgery, Jennie received a car from the Red Cross representative who told her the transplant was successful. "I feel good, and I think it will actually work for her. " She said, "So many people say that they'd only donate if it was for a family member or close friend. This woman was someone's family and someone's friend. Obviously no one she knows is a match, and the fact that you'd be able to help a perfect stranger is greater. " Jennie gave her bone marrow to _ . | [

mmlu_train_61132 | The Olympic Games are seen as the greatest test of an athlete's ability and are supposed to celebrate the spirit of fair play. But in fact, sportsmen have been using drugs to cheat their way to victory since the Games first began. In the early years, athletes ate mushrooms and plant seeds to improve their performance. Nowadays, this kind of cheating has a name doping . Just last month, Britain's top sprinter Dwain Chambers and several American athletes tested positive for the drug THG. Until a coach secretly gave a sample of THG to scientists, no one knew how ho test for it. "We're like cops chasing criminals--athletes are always adapting and looking for areas we haven't investigated," said Jacquew de Ceaurriz, a French anti-doping expert. Since the first drugs test was carried out at the 1968 Olympics in Mexico City, many cheats have been caught out. The most famous case in history is that of Canadian sprinter Ben Johnson. He broke the 100 meters world record in winning gold at the 1988 Seoul Olympics. But days later, he tested positive for drug use, lost his gold medal and was banned from the sport. Five years later, he returned to action--only to be found positive again and banned forever. China has also had problems with drug cheats. At the 1994 Asian Games, 11 Chinese athletes--seven of them swimmers--tested positive for banned drugs. Sports organizations promised that cheating on this scale would not happen again. Experts are also worried that doping can damage a person's health. It is believed to increase the risk of liver and kidney diseases, and women may experience reproductive problems. As long as they can stay ahead of the scientists, it is unlikely the cheats will stop. But experts say there is a limit to what can be achieved and that athletes will not be able to change their bodies using gene technology. "For the moment, genetic doping does not exist," said de Ceaurriz. "Even in 10 or 15 years it will not be done easily--the scientific community will not let it happen." Which of the following is not the way that some athletes cheat to their better sports achievements? | [

mmlu_train_59500 | Switching telephone providers used to be the only way homeowners could save money on telephone bills. Now thanks to new technology, comsumers have another choice-making phone calls over the internet. And this can be completely free if you call another person with an internet phone set-up. The technology is called voice over internet protocol , or VoIP. In 2005, consumer demand for VoIP dramatically grew. In the US, where popularity has grown faster than here in the UK, 8.4 million are predicted to subscribe this year. For the past couple years, VoIP pioneers such as Skype have accounted for the majority of internet phone subscribers. VoIP is attractive to consumers because it's cheaper than traditional phone services. With the basic equipment of PC, microphone and headset, and VoIP software and broadband internet for optimum voice quality, consumers can save a fortune chatting for free to other internet phone owners and save money calling regular landlines . But, as the saying goes, . Many of these services suffer from uncontinuous lapses in quality. While some users may tolerate echoes or a dropped call, improved quality is needed to attract more customers. Computing has examined the benefits of using a PC as a telephone with VoIP in how easy they were to set up, how effective they were and the range of their features. Skype(www. skype.com) came top for its bother-free approach, easy set-up and exceptional voice clarity. Sipgate (www. sipgate. co. uk), MSN(www. messenger. msn. co. uk) and Yahoo! Messenger (uk. messenger. yahoo. com) provide an audio "wizard" that improves sound levels. Google Talk (www. google. com/ talk) was less helpful and Babble. net (www. babble. net) was let down by its poor help files. Yahoo!

mmlu_train_50811 | No one knows why we sleep, but it's certain that we need to. People who are prevented from sleeping begin to suffer obvious effects after a few days--they think less clearly, and they fall asleep during the working hours; some may have hallucinations . There are no rules about sleep. Generally speaking, grown-ups sleep about 7 and a half hours each night and probably more than 60 per cent get between seven and eight hours. But perhaps eight per cent are quite happy with 5 hours or less, and four per cent or so find that they want ten hours or more. If you feel all right, you're probably getting enough sleep. The important thing is not to worry how much other people get--their needs may be different. Exercise doesn't seem to increase the need for sleep--office workers, for example, sleep for about as long as people doing physically active work. Children sleep more than grown-ups--perhaps 14 to 18 hours soon after birth, going down to grown-up levels by early teenage. Sleep patterns also tend to be different in the elderly, who may sleep less at night than they did when younger, find sleep getting more broken, and often make it a rule to sleep during the daytime.

mmlu_train_62739 | American beekeeping operations have been hit hard by what scientists call colony collapse disorder(C.C.D.). Almost half of their worker bees have disappeared during the past season. C.C.D. has also been reported in Israel, Europe and South America. Bees fly away from the hive and never return. Sometimes they are found dead; other times they are never found. Many crops and trees depend on pollination by bees to help them grow. A new report says virus may be at least partly responsible for the disorder in honey bee colonies in the United States. This virus is called Israeli acute paralysis virus. It was first identified in Israel in 2004. Ian Lipkin at Columbia University in New York and a team reported the new findings in Science magazine. Doctor Lipkin says the virus may not be the only cause. He says it may work with other causes to produce the collapse disorder. The team found the virus in colonies with the help of a map of honey bee genes that was published last year. They examined thirty colonies affected by the disorder. They found evidence of the virus in twenty-five of them, and in one healthy colony. The next step is further testing of healthy hives. The researchers suggested that the United States may have imported the disorder in bees from Australia. They say the bees may carry the virus but not be affected. The idea is that unlike many American bees, the ability of Australian bees to fight disease has not been hurt by the varroa mite . This insect attacks honey bees, which could make the disorder more likely to affect a hive. Australian bee producers reject these suspicions. And some researchers suspect that bee production in the United States is down mainly because of the weather. Honey bees gather nectar from flowers and trees. The sweet liquid gives them food and material to make honey. But cold weather this spring in the Midwest reduced the flow of nectar in many flowers. Many bees may have starved. Dry weather in areas of the country could also be playing a part. Wayne Esaias is a NASA space agency scientist who keeps bees in his free time. He lives in central Maryland, where he has found that flowers are blooming a month earlier than they did in 1970, which may be partly responsible for the disorder. Wayne Esaias is organizing a group of beekeepers to document nectar flow around the country. How many possibilities may be involved in the bee disorder according to the passage? | [

mmlu_train_39600 | Europeans should try to stay indoors if ash from Iceland's volcano starts settling, the World Health Organization warned Friday as small amounts fell in Iceland, Scotland and Norway. WHO spokesman Daniel Epstein said the tiny ash is potentially dangerous for people when it starts to reach the Earth because particles taken in by people can enter the lungs and cause breathing problems. And he also said Europeans who go outside might want to consider wearing a mask. Other experts, however, weren't convinced the volcanic ash would have a major effect on peoples' health and said WHO's warnings were " _ ." They said volcanic ash was much less dangerous than cigarette smoke or pollution. Volcanic ash is made of fine particles of fragmented volcanic rock. It is light gray to black and can be as fine as talcum powder . During a volcanic eruption, the ash can be breathed deep into the lungs and cause irritation (,) even in healthy people. But once it falls from a greater distance -- like from the cloud currently hovering above Europe -- its health effects are often minimal, experts say. "Not all particles are created equal," said Ken Donaldson, a professor at the University of Edinburgh, "In the great scheme of things, volcanic ash is not all that harmful." And he said most Europeans' exposure to volcanic ash would be ignored and that only those in the near districts of the Icelandic volcano would likely be at risk. Dr. Stephen Spiro, a professor of the British Lung Foundation, said the further the particles travel, the less dangerous they will be. "The cloud has already passed over northern Scotland and we haven't heard of any ill effects there," he said. Spiro said to wear masks or stay indoors to avoid volcanic ash was "over the top" and "a bit hysterical." The text is mainly about _ . | [

Patterns of diet were old-styled, based firmly on 'meat and two vegetables' (somewhat overcooked), potatoes (of course) and large quantities of dairy produce. Now things are very different. Tourist demands for predictable, inexpensive fast-food are met, as everywhere, with hamburgers and pizzas - a better bet being fish and chips. But more sophisticated tastes have introduced wholefoods and vegetarian restaurants (almost unheard of before), and a vast number of new restaurants, often French in style, have opened in the main tourist centres. Food 'events' such as Kinsale's Gourmet festival or Galway's Oyster Festival attract large numbers of visitors and reflect the new interest in food. Whatever Irish cooking lacks in finesse , it nearly always makes up for in plenty, and ingredients are of a high quality. Home-grown produce includes rich dairy foods, beef, lamb and pork, and a great variety of seafood. One of its great specialities is soda bread. It is made with buttermilk and is served fresh and warm with every meal. Recently there has been a return to simple Irish foods such as stews and potato dishes. One of the best-value meals in Irelandis breakfast. A 'traditional Irish breakfast' is a plateful of bacon and eggs with soda and potato breads. Accommodation rates are nearly always quoted with a full breakfast included, so you might as well eat enough to keep you going all day and get your money's worth! How does the passage describe Irish cooking today? | [

mmlu_train_12966 | More and more, the operations of our businesses, governments, and financial institutions are controlled by information that exists only inside computer memories. Anyone clever enough to modify this information for his own purposes can get big reward. Even worse, a number of people who have done this and been caught at it have managed to get away without punishment. It's easy for computer crimes to go undetected if no one checks up on what the computer is doing. But even if the crime is detected, the criminal may walk away not only unpunished but with a glowing recommendation from his former employers. Of course, we have no statistics on crimes that go undetected. But it's disturbing to note how many of the crimes we do know about were detected by accident, not by systematic inspections or other security procedures. The computer criminals who have been caught may have been the victims of uncommonly bad luck. Unlike other lawbreakers, who must leave the country, commit suicide, or go to jail, computer criminals sometimes escape punishment, demanding not only that they not be charged but that they be given good recommendations and perhaps other benefits. All too often, their demands have been met. Why? Because company executives are afraid of the bad publicity that would result if the public found out that their computer had been misused. They hesitate at the thought of a criminal boasting in open court of how he juggled the most confidential records right under the noses of the company's executives, accountants, and security staff. And so another computer criminal departs with just the recommendations he needs to continue his crimes elsewhere. It can be concluded from the passage that _ . | [

Zhou Yunyun,22,a senior finance major at Jilin University,has decided that instead of traveling to Hainan province,he will kill the time by playing computer games with his online friends. "I'm used to chatting and playing with them every day.It's just fun to make friends this way,"he said."When I returned home in past years,my relatives always asked me a lot of questions about my plans after graduation.They had high expectations of me,which made me feel stressed," said Zhou.

If someone steals it, he'll get chances to steal something else. We use passwords everywhere in our life. We are so used to passwords that we don't pay any attention to them until we lose or forget one. A study of 28,000 passwords recently stolen from a popular website showed that people often do the easy thing. It found that 16% took a first name as a password. Another 14% used the easiest keyboard combinations such as "12345678"or "QWERTY". 5% of the stolen passwords were names of television shows or stars popular with young people. 3% of the passwords expressed feelings like "I don't care", "Whatever", "I love you" or their opposite, "I hate you". Robert Graham, who did the study, advises people to choose a password that is longer than eight characters with one capital letter and one symbol. Of course, safe passwords don't mean those hard to remember. Forgetting your password is sometimes a big headache for you. Maybe, the perfect password is easy for you and hard for others. ,,.

Numerous vacations help the couple to maintain their health and emotional well-being-and it's no surprise to health care professionals. "Rest,relaxation, and stress reduction are very important for people's weLl-being and health. This can be accomplished through daily activities,such as exercise and meditation,but vacation is an important part of this as well," said primary care physician Natasha Withers from One Medical Group in New York. Withers lists a decreased risk of heart disease and improved reaction time as some of the benefits from taking some time off. "We also know that the mind is very powerful and can help with healing,so a rested,relaxed mind is able to help the body heal better," said Withers. Psychologists confirm the value of vacations for the mind. " The impact that taking a vacation has on one's mental health is great," said Francine Lederer,a clinical psychologist in Los Angeles who specializes in stress and relationship management. " Most people have better life perspective and are more motivated to achieve their goals after a vacation,even if it is a 24- hour time-out. " The trips could be good for their health,good for their family and good for their .businesses. The online travel agency Expedia conducted a survey about vacation time in 2010,and according to their data the average American eamed 18 vacation days-but only used 14 0f them. France topped the list,with the average worker earning 37 vacation days and using all but two of them. Americans' responses may not be surprising in a culture where long hours on the job often are valued,but that's not always good for the individual,the family or the employer. Psychologists have also found that people who don't take enough time to relax may find it harder to relax in the future.

mmlu_train_60751 | Over the next 20 to 50 years, it will become harder to tell the difference between the human and the machine. All body parts will be replaceable. A computer will function like the human brain with the ability to recognize feelings and respond with emotions. They can then make fake people. We will then be able to create a machine duplicate of ourselves so we will appear to be alive long after we are dead. Maybe a few decades later, a way will be found to transfer our spirit to the new body. Then we can choose to live for as long as we want. Once one of you is duplicated, you will just have to press Ctrl + D and you will have two of you. If you want 500, select 500. Naturally, when duplicates are running around all over the place, there will be a food problem. The most practical choice would be garbage. Your modified duplicate will be made to eat garbage like a goat. But don't worry. Their taste buds and sense of smell will be changed so they will really enjoy it. They will want to eat lots of garbage. When it becomes possible to do a spirit transfer, you will be able to live within whichever duplicate you want, whenever you want and as long as you want. Just imagine what it would be like when you are with so many duplicates of yourself. You will be very busy enjoying many things. One duplicate of yourself is in the middle of doing a jigsaw puzzle and another duplicate has almost completed another puzzle.

Take a look at what Albert Einstein was doing at the age of 26. 100 years ago, Einstein was working in Switzerland. His hobby was physics. Without much money or help, he wrote five papers for a physics magazine. Three of these greatly changed the study of physics and our understanding of space, time, light and matter . His most famous work is on the Theory of Relativity . Einstein was given the Nobel Prize for his discoveries. Although he also did many other things later, the years 1905 has been called Einstein's "Year of Wonders". It has been 100 years since then. Because of this, the UN has named 05 the World Year of Physics. Today, over fifty years after Einstein's death, a question is asked, " Will there ever be another Einstein?" It may take a long time. After all, Einstein was born more than 200 years after Sir Isaac Newton, another great scientist. Besides, physics is a different field now, and education is different, too. Even if you can't be the next great scientist, it is still helpful to remember some of the things that made Einstein great. He thought independently and read widely.

mmlu_train_58302 | Ever wonder how much a cloud weighs? What about a hurricane? A meteorologist has done some estimates and the results might surprise you. Let's start with a very simple white puffy cloud -- a cumulus cloud . How much does the water in a cumulus cloud weigh? Peggy LeMone, senior scientist at the National Center for Atmospheric Research in Boulder, Colorado, did the numbers. "The water in the little cloud weighs about 550 tons," she calculates. "Or if you want to convert it to something that might be a little more meaningful ... think of elephants." The thought of a hundred elephants-worth of water suspended in the sky begs another question -- what keeps it up there? "First of all, the water isn't in elephant sized particles , it's in tiny tiny tiny particles," explains LeMone. And those particles float on the warmer air that's rising below. But still, the concept of so much water floating in the sky was surprising even to a meteorologist like LeMone. "I had no idea how much a cloud would weigh, actually, when I started the calculations," she says. So how many elephant units of water are inside a big storm cloud--10 times bigger all the way around than the "puffy" cumulus cloud? Again, LeMone did the numbers: About 200,000 elephants. Now, ratchet up the calculations for a hurricane about the size of Missouri and the figures get really massive. "What we're doing is weighing the water in one cubic meter theoretically pulled from a cloud and then multiplying by the number of meters in a whole hurricane," she explains. The result? Forty million elephants. That means the water in one hurricane weighs more than all the elephants on the planet. Perhaps even more than all the elephants that have ever lived on the planet.

Lichens live on rocks, branches, houses, and even metal street signs. You can find these colorful organisms almost everywhere -- from deserts to rainforests, and from Antarctica to Africa. They've traveled in outer space, and some scientists think there might even be lichens on Mars. What you probably don't realize is that a lichen is more than a single thing. It includes two different types of living organisms: a fungus and an alga . Neither of these organisms is a plant, so the lichen isn't a plant either. Through photosynthesis , the alga gets the sun's energy to make food for the fungus, which is the place for the alga to live in. However, the alga cannot leave the fungus. Around the world, scientists have found tens of thousands of types of lichens. Many may not even have been discovered yet. As scientists continue to find new kinds of lichens, they are also working to understand how they are connected to one another.

mmlu_train_61778 | Space is where our future is -- trips to the Moon, Mars and beyond. Most people would think that aside from comets and stars, there is little else out there. But, since our space journey started we have left so much trash there that scientists are now concerned that if we don't clean it up, we may all be in mortal danger. The first piece of space junk was created in 1964, when the American satellite Vanguard I stopped operating and lost its connection with the ground center. However, since it kept orbiting around the Earth without any consequences, scientists became increasingly comfortable abandoning things that no longer served any useful purpose in space. It is estimated that there are now over 500,000 pieces of man-made trash orbiting the Earth at speeds of up to 17,500 miles per hour. The junk varies from tiny pieces of paint chipped off rockets to cameras, huge fuel tanks, and even odd items like the million-dollar tool kit that astronaut Heidemarie Stefanyshyn Piper lost during a spacewalk. The major problem with the space trash is that it may hit working satellites and damage traveling spacecraft . Moreover, pieces of junk may collide with each other and break into pieces which fall back to the Earth. To avoid this, scientists have invented several ways for clearing the sky. Ground stations have been built to monitor larger pieces of space trash to prevent them from crashing into working satellites or space shuttles. Future plans include a cooperative effort among many nations to stop littering in space and to clean up the trash already there.

mmlu_train_40749 | At night, bats fly through the air, catching hundreds of insects and other small animals. But during the day, they hardly move at all. Instead, bats pass the time hanging upside down from a secret spot. There are a couple of reasons why bats rest this way. First of all, it puts them in a position for takeoff. Unlike birds, bats can't fly into the air from the ground. Their wings don't produce enough lift to take off from a dead stop, and their hind legs are so small and underdeveloped that they can't run to build up the necessary takeoff speed. Instead, they use their front claws to climb to a high spot, and then fall into flight. During the hours when most enemies are active, bats gather where few animals would think to look and most can't reach. This allows them to disappear from the world until night comes again. There's also little competition for these resting spots, as other flying animals don't have the ability to hang upside down. Bats have a unique physiological adaptation that lets them hang around this way without using any energy. For you to hold your fist around an object tight, you contract several muscles in your arm, which are connected to your fingers by tendons ;as one muscle contracts, it pulls a tendon, which pulls one of your fingers closed. A bat's talons close in the same way, except that their tendons are connected only to the upper body, not to a muscle. To hang upside down, a bat pulls its claws open with other muscles. To get the talons to take hold of the surface, the bat simply lets its body relax. The weight of the upper body pulls down on the tendons connected to the talons, causing them to hold tight. Therefore, the bat doesn't have to do anything to hang upside down. Bats hang upside down because _ . | [

mmlu_train_33524 | California has a new program called the Digital Textbook Initiative. "Starting this fall with high school math and science, we will be the first state in the nation to provide schools with a state-approved list of digital textbooks." That was Governor Arnold Schwarzenegger in June, talking about his effort to get schools to use materials available free online. He listed reasons why he thinks digital textbooks make sense. California approves traditional textbooks in six-year cycles. Digital ones can offer the latest information. They lighten the load of school bags. They save paper and trees, and make learning more fun and interactive. And above all, he said, they help schools with their finances. The state has had to make severe cuts in school spending because of deep financial problems. More than six million students attend California public schools. Earlier this year, California invited content developers to offer digital math and science materials for high schools. These had to meet at least 90% of the state's learning requirements. Specially trained teachers examined 16 textbooks and approved ten of them. Six of the ten were published by the CK 12 Foundation, a nonprofit group that had been developing digital science and math books for about two years. The foundation paid teachers and other education professionals to write and edit them. The money came from a group financed by the Khosla Family. California cannot require schools to use the digital textbooks. Individual school districts will have to decide for themselves. Susan Martimo, a California Department of Education official, says she does not expect widespread use right away. Her best guess is that some schools with a lot of technology will be the first to use them, but only in addition to their traditional books. School administrators point out that the texts may be free online, but students need a way to access them. Not everyone has a computer or electronic reader. Schools could print out copies, but that would not help the environment. Also, there is the cost to train teachers to use digital textbooks effectively. Digital textbooks are most meaningful in that they are to _ . | [

mmlu_train_12017 | An oral drug, named ERDRP-0519, was invented. It is specifically designed to protect people who got infected measles from spreading the virus to others. Like the flu, measles spreads through the air by breathing, coughing or sneezing. There is typically a time, about two weeks, between becoming infected with the virus and the beginning of symptoms like skin rash , runny nose, heavy cough and high fever. "This therapy application determines the desired characteristics of the drug, which are orally available, cost-effective manufacture and high stability," Richard Klemperer, professor of Georgia State University, told reporters last Wednesday. "With these criteria in mind, we have developed a small drug that blocks the measles virus over the past years, which is essential for copy of the virus." The researchers tested the drug in rats infected with canine distemper virus , which is a close relative of measles virus. They found that all of the infected rats treated with the drug survived the deadly infection, showed no clinical signs of disease and developed a strong protective immune response. The drug could be used to treat friends, family and other social contacts of a person infected with measles virus, which have not developed symptoms yet but are at risk of having caught the disease, Klemperer said truthfully. "The emergence of strong antiviral immunity in treated animals is particularly encouraging, since it suggests that the drug may not only save an infected individual from disease but contribute to closing measles immunity gaps in a population," Klemperer said. The researchers emphasized the drug is not intended as a substitute for vaccination, but as an additional weapon to get rid of the measles. They planned to test the drug's safety in larger animals, before moving into clinical trials in humans. "If our next series of studies confirms that the human situation mirrors what we have seen in rats, then this drug may make a major contribution to getting rid of measles by preventing local outbreaks" Klemperer said. Despite the existence of an effective vaccine, annual measles deaths worldwide have remained constant at around 150,000 since 2007. The reasons for this are the highly infectious nature of the virus, in the developing world largely due to issues of resources, and in many developed countries in particular in the European region due to parental concerns regarding vaccination safety.

mmlu_train_7069 | In a few years,you might be able to speak Chinese,Korean,Japanese,French,and English-and all at the same time. This sounds incredible,but Alex Waibel,a computer science professor at US's Car-negie Mellon University (CMU) and Germany's University of Karlsruhe,announced last week that it may soon be reality. He and his team have invented software and hardware that could make it far easier for people who speak different languages to understand each other. One application,called Lecture Translation,can easily translate a speech from one language into an-other. Current translation technologies typically limit speakers to certain topics or a limited vocabulary. Us-ers also have to be trained how to use the programme. Another machine can send translations of a speech to different listeners depending on what languagethey speak. "It is like having a s _ translator right next to you but without disturbing the person next to you,"Waibel said Prefer to read? So- called Translation Glasses transcribe the translations on a tiny liquid-crystal display(LCD) screen. Then there's the Muscle Translator. Electrodes capture the electrical signals from facial muscle movements made naturally when a person is mouthing words. The signals are then translated into speech.The electrodes could be replaced with wireless chips implanted in a person's face,according to research-ers. During a demonstration held last Thursday in CMU's Pittsburgh campus,a Chinese student named Sang Jun had 11 tiny electrodes attached to the muscles of his cheeks,neck and throat. Then he mouthed-without speaking aloud- a few words in Mandarin to the audience. A few seconds later,the phrase was displayed on a computer screen and spoken out by the computer in English and Spanish: "Let me introduce our new prototype." This particular instrument,when fully developed,might allow anyone to speak in any number of lan-guages or,as Waibel put it,"to switch your mouth to a foreign language". "The idea behind the universi-ty's prototypes is to create'good enough' bridges for cross- cultural exchanges that are becoming more common in the world,"Waibel said. With spontaneous translators,foreign drivers in Germany could listen to traffic warnings on the radio; tourists in China could read all the signs and talk with local people;leaders of different coun-tries could have secret talks without any interpreters there. What's the final destination of inventing the language translators? | [

mmlu_train_69924 | When you are learning English, you find it not clever to put an English sentence, word for word, into your own language. Take the sentence "How do you do?" as an example. If you look up each word in the dictionary, one at a time, what is your translation ? It must be a wrong sentence in your own language. Languages do not just have different sounds, they are different in many ways. It's important to master the rules for word order in the study of English, too. If the speaker puts words in a wrong order, the listener can't understand the speaker's sentence easily.Sometimes when the order of words in an English sentence is changed, the meaning of the sentence changes. But sometimes the order is changed, the meaning of the sentence doesn't change. Let's see the difference between the two sentences:"She only likes apples. " "Only she likes apples. " When you are learning English, you must use it as the English speaker does. From the passage we know that _ when we are learning English. | [

But did you know that there are ways to make your brain healthier and smarter? Studies show that when the brain is _ to do something new, it creates new neural pathways . The more pathways you have, the faster you can think and the better memory you will have. Ten steps toward a smarter brain Limit your TV time Watching an average TV show requires very little brain power and brings the same result as neglecting physical exercise. Your brain will become weak just as your muscles do. If you watch TV, choose something educational and informative. Travel Traveling to a new country forces you to see and do things in a new way, providing stimulation to the brain. Learn a new language Acquiring a new language involves different learning methods. Learning a language sharpens your brain and helps prevent memory problems in later years. Master a new subject Each week, select an animal, a bird or a fish, and read everything you can about it. Stretch your brain as you become an expert on the subject. Use your non-dominant hand If you are right-handed, use your left hand for everyday activities, or use your right hand if you are left-handed. Doing familiar things in a new way will cause your brain to create new neural networks. Read often As you read, take the time to look up people or places that aren't familiar. Reading expands your vocabulary if you search for words and definitionsthat you don't know. Do puzzles According to the Mayo Clinic, doing sudoku and crossword puzzles keeps the brain sharp into your senior years. Calculate while you shop As you put things in your grocery cart, total everything in your head. See how much close you get to the actual total. Play video games Studies have found that certain video games force you to use critical decision-making skills and can even improve students' math scores.

mmlu_train_59441 | A little under one-third of U.S. families have no Internet access and do not plan to get it, with most of the holdouts seeing little use for it in their lives, according to a survey released on Friday. Park Associates, a Dallas-based technology market research firm, said 29 percent of U.S. families, or 31 million homes, do not have Internet access and do not intend to subscribe to an Internet service over the next 12 months. The second annual National Technology Scan conducted by Park found that the main reason why potential customers say they do not subscribe to the Internet is because of the low value to their daily lives rather than concerns over cost. Forty-four percent of these families say they are not interested in anything on the Internet, versus just 22 percent who say they cannot afford a computer or the cost of Internet service, the survey showed. The answer "I'm not sure how to use the Internet" came from 17 percent of participants who do not subscribe. The response "I do all my e-commerce shopping and YouTube-watching at work" was cited by 14 percent of Internet-access refuseniks. Three percent said the Internet doesn't reach their homes. The study found U.S. broadband adoption grew to 52 percent over 2006, up from 42 percent in 2005. Roughly half of new subscribers converted from slower-speed, dial-up Internet access while the other half of families had no prior access. "The industry continues to chip away at the core of non-subscribers, but has a long way to go," said John Barrett, director of research at Parks Associates. "Entertainment applications will be the key. If anything will pull in the holdouts, it's going to be applications that make the Internet more similar to pay-TV," he predicted.

mmlu_train_77040 | What's the strongest part of your body? Your head? Bones? It's your teeth. There is a special thing called enamel in teeth. It is the hardest thing in the human body and keeps bacteria away. However, teeth are hurt easily to problems and disease. September 20 is National Teeth-loving Day in China. Let's pay attention to the health of our teeth. Teeth problems are common around the world. Most children and young adults have tooth decay . A study which come out on China Health Monthly magazine this year showed that 40.74% of a sample of 1,306 Chinese students under age 15 has decayed teeth. Food that is rich in sugar increases the risk of tooth decay. After you eat, bacteria go crazy over the sugar on your teeth. The bacteria turn sugar into acids that eat away at tooth enamel. This causes holes in your teeth. Another common problem is crooked teeth . When your new teeth begin to grow and the old teeth haven't fallen out, there isn't enough space for the new ones. This causes crooked teeth. Don't worry. Here are some ways to keep your teeth healthy. *Brush at least twice a day in the morning and in the evening. *Learn to use dental floss . The floss gets rid of food that's hidden where your toothbrush can't get it. *Visit a dentist. He or she can check if you have any dental problems and help you clean your teeth. *Pay attention to what you eat. It's better to eat lots of fruit and vegetables instead of fries and drink water instead of soda. *Wear braces to make your teeth straight and beautiful.
