mmlu_train_5597 | Turns out we aren't good at walking and talking at the same time, according to a study of pedestrians on their cell phones. Nearly one-third of pedestrians (29.8% ) were distracted by their mobile devices while crossing the street, say researchers of a study published online in the journal Injury Prevention. Just as drivers who text, talk on cell phones, or adjust MP3 players increase their risk of losing control of their vehicles, pedestrians distracted by their conversations or their devices also put themselves at higher risk of getting into an accident. During the summer of 2012, scientists in Seattle, Wash. , studied 1,102 pedestrians at 20 crossroads seeing the city * s highest number of pedestrian injuries over the past few years. They watched how pedestrians crossed the street @ whether they looked both ways or obeyed the crossroad signal @ and also recorded how long it took pedestrians to do so.Distractions included listening to music with headphones, using a cell phone or earpiece to talk on a cell phone, text messaging, and talking with another person. Overall, researchers found the most common distraction among pedestrians was listening to music (11.2%), followed by text messaging (7.3%), and using a handheld phone(6.2%). But the most absorbing distraction was texting. Compared to pedestrians who were not distracted, those who were texting took 1.87 seconds longer to cross and were four times more likely to not look where they were going, disobey traffic lights, or cross outside of the crosswalk. While the study did not track injuries related to these trends, previous studies have linked such activities to a higher risk of being injured while crossing the street. Combined with the rise in the use of mobile devices, especially smart phones, the results raise concerns that multi-tasking while walking may be a rising concern for pedestrians. And that danger may only climb, as the number of wireless devices has already _ the population of the United States. Last year, roughly 1,152 people wound up in the emergency room to treat injuries caused by using a cell phone or electronic device, the Consumer Product Safety Commission told the Associated Press in July. Those numbers may be underestimated, however, because patients may not always admit that they were using their phones along with other activities such as walking or driving when they were hurt.

mmlu_train_21912 | Carrot juice, because of its many healthy benefits, is commonly called the "magic juice". It has been found that adding carrot juice to people's diets greatly improves their health. And its delicious taste makes it popular with all members of the family as a beverage. Carrot juice is one of the richest sources of vitamin A that can be used in the daily diet. Lack of vitamin A can cause dryness and damage to the skin, nails and hair. Drinking carrot juice to increase the vitamin A in the diet is said to be good for many parts of the body, including the bones and teeth. Drinking carrot juice is thought to be extremely helpful to the liver , because vitamin A helps to clean the liver and reduce fat in it. And it is suggested that drinking carrot juice should be done regularly, rather than just from time to time. Drinking carrot juice is also thought to improve the eyesight because of the vitamin A in the juice. Lack of vitamin A can lead to night blindness, which can be very dangerous, especially when the person is driving a car. An easy way to find out if you are lacking in vitamin A is to walk from a bright room into a dark room. Your eyes may have some trouble in getting used to the change of light if you are lacking in vitamin A. How can you make carrot juice? Wash some carrots well in cold water. Scrape them lightly, but do not peel them, as this will take away valuable vitamins and minerals that lie close to the skin. Lack of vitamin A can lead to _ . | [

mmlu_train_64777 | Living near the beach may come with an extra perk : better health. A new study analyzed information from more than 48 million people in England and found that the nearer they lived to the coast, the more likely people were to report good health within the past year. Living near the coast may be associated with better health because the seaside environment reduces stress, the researchers said. They pointed to another British study that found that people who took trips to the coast experienced more feelings of calmness and relaxation than those who visited urban parks or the countryside. The difference from living near the coast was relatively small. But a small effect, when applied to an entire population, can have a substantial impact on public health, said study researcher Ben Wheeler of Peninsula College of Medicine and Dentistry in Exeter, England. However, it's too soon to advise people to hit the beach to improve health, Wheeler said. The study only found an association, not a cause-effect link, and it's possible that other factors could explain the results. For instance, it could be that people who are wealthier, and therefore healthier, are more able to move to desired locations such as the coast, Wheeler said, a phenomenon known as the migrant effect. But the study did find that the association between coastal living and better health was strongest for those living in the poorest areas, which perhaps indicates that wealth cannot explain the results, Wheeler said. Because the study looked at only England--an island country in which everyone lives within 72 miles of the coast--it's not clear whether the findings would apply to other populations. Far from England, a health expert not involved in the study said that while the British research certainly doesn't prove that people's health and the place they live are linked, it's possible that _ to the seas does something for our bodies. If future studies confirm the results, the next step would be to find out it is what coastal environments that can benefit health. Wheeler said it may then be possible to bring those benefits to people living in other areas, through virtual environments, for instance. What Ben Wheeler said means _ . | [

mmlu_train_8833 | In meditation ,people sit quietly and focus their attention on their breath .As they breathe in and out ,they attend to their feelings .As thoughts go through their minds. They let _ go. Breathe .Let go .Breathe .Let go . According to a recent study at the Insight Meditation Society in Barre,Massachusetts. Three months of training in this kind of meditation causes a market change in how the brain allocates attention. It appears that the ability to let go thoughts that come into mind frees the brain to attend to more rapidly changing things and events in the outside world. Expert mediators are better than other people at catching such fast-changing stimuli( ),like facial expressions. The study provides evidence for changes in the workings of the brain with mental training. People can learn and improve abilities of all sorts with practice, everything from driving to playing the piano. The study has shown that meditation is good for the brain. It appears to reduce pressure and promote a sense of well-being. In an experiment, 17 volunteers with no meditation experience in the experimental group spent three months meditating 10 to 12 hours a day .A control group also with no meditation experience meditated for 20 minutes a day over the same period .Both groups were then given the tests with two numbers in a group of letters. As both group looked for the numbers , their brain activity was recorded. Everyone could catch the first number .But the brain recordings showed that the less experienced mediators tended to grasp the first number and hang onto it, so they missed the second number .Those with more experience gave less attention to the first number .as if letting it go ,which led to an increased ability to grasp the second number ,This shows that attention can change with practice. Just ask Daniel Levision , who meditated for three months as part of the study ."I am a much better listener," he said . " I do not get lost in my own personal reaction to what people are saying." In the experiment ,volunteers doing meditation for longer hours _ . | [

mmlu_train_62019 | If you see someone drowning, speed is very important. Once you get him out of the water, if he isn't breathing, you have four minutes before his brain is completely destroyed. Support his neck, move his head back and press his chin upwards. This stops the tongue blocking the airway in the throat and is sometimes enough to get him breathing again. If that doesn't work, start mouth-to-mouth breathing. Press his nostrils (the two holes at the end of your nose, through which you breathe and smell things) together with your fingers. Open your mouth and take a deep breath. Blow into his lungs until his chest rises, then remove your mouth and watch his chest fall. Repeat twelve times a minute. Keep doing until professional help arrives. To bring a child back to life, keep your lips around his mouth and gently blow into his mouth. Give the first four breaths as quickly as possible to fill the blood with oxygen. If, in spite of your efforts, he starts turning a blue-grey colour, and you can feel no pulse , then pressing is the last chance of saving his life. With arms straight, rock forwards, pressing down on the lower half of the breastbone. Don't be too hard or you may break a rib.

mmlu_train_82015 | You've heard of 3D printing from newspaper and TV programs. It can "print" in plastic, metal, nylon, and over a hundred other materials. 3D printing technology has been around since the 1980s, it was not widely used until the early 2010s. The first working 3D printer was created in 1984 by Chuck Hull. 3D printers use many different types of technologies, but they all share one thing in common: they create a three-dimensional object by building it layer , by continuing layer, until the whole object is completed. Imagine a baker lay down each layer one at a time until the whole cake is formed. 3D printing is somewhat similar, but just a bit stricter. How can 3D printers work so well? The most important thing-a program, a 3D printer also needs to have instructions for what to print from a computer. It needs a file as well. The file which is a Computer Aided Design (CAD) paper is created with the use of a 3D modeling program. The program creates a paper that is sent to the 3D printer. Along the way, software pieces the design into hundreds, or more likely thousands of layers. The 3D printer builds up one layer at a time, from the bottom to the top, until the object is done. 3D printings can be used for making many kinds of things such as machine parts, daily life objects, even human organs using a person's own cells.

mmlu_train_39522 | The next time you try for a high-ranking post, you could let your possible boss listen to a recommending phone call "made" by US President George W Bush or British Prime Minister Tony Blair. Of course, neither of them could really do that for you-you would just "borrow" their voices. AT & T labs will start selling speech software that it says is so good at reproducing the sounds of a human voice that it can recreate voices and even bring the voices of long-dead famous people back to life. The software, which turns printed text into speech, makes it possible for a company to use recordings of a person's voice to say things that the person never actually said. Possible customers for the software, which is priced in the thousands of dollars, include telephone call centers, companies that make software that reads digital files aloud, and makers of automated voice devices . The advances raise several problems. Who, for example, owns the rights to a famous person's voice? (Some experts even believe that new contracts will be drawn that include voice-licensing clauses.) And although scientists say the technology is not yet good enough to commit fraud , would the synthesized voices at last be able to trick people into thinking that they were getting phone calls or digital audio recordings from people they know? Even Mr Fruchterman, one of AT & T lab's possible first customers, said he wondered what the new technology might bring. "Just like you can't trust a photograph anymore."

mmlu_train_38036 | Laughter healing benefits and healing with laughter have become synonymous with Norman Cousins, the man who laughed himself to wellness. Norman Cousins was the editor of SaturdayReviewfor over 30 years. His story began in 1964, when doctors found that the connective tissue in his spine was becoming worse, which is a condition known as Ankylosing Spondylitis . The doctors, one of whom was a close friend of Cousins, said that his chance of survival was approximately 1 in 500. He read about the theory that negative emotions do harm to the body, so he thought that if negative emotions were damaging to health, then positive emotions should improve health. Faced with the real possibility of his approaching death, Cousins thought long and hard and eventually did three things completely contrary to medical opinion. First he began his own research on all of the various drugs he was on. He discovered that his condition was removing Vitamin C from his body and, based on Cousins' personal research, doctors agreed to take him off several of the drugs he was on and inject him with large doses of this supplement , as Cousins felt this may be his last hope. Secondly, Cousins made a decision to check out of the hospital and into a hotel room. The third thing Cousins did was get a movie projector and a large supply of funny films. On his first night in the hotel Cousins found that he laughed so hard at the films that he was able to stimulate chemicals in his body that allowed him several hours of pain-free sleep. When the pain returned he would simply turn the projector back on and the laughter would help sleep, and he was able to measure the changes in his body by measuring his blood sedimentation rate , and found that this rate dropped by at least 5 points each time he watched one of these videos. The treatment proved to be so effective that in very little time Cousins was off all painkillers and sleeping pills. He found that the laughter relieved the pain and helped him sleep. He returned to work and wrote about his experimental treatment in his book Anatomy of an Illness. In 1989, it was finally acknowledged in the Journal of the American Medical Association that laughter therapy could help improve the quality of life for patients with chronic illness and that laughter has an immediate symptom-relieving effect. According to Norman Cousins' own research, _ may be good for his recovery. | [

mmlu_train_41128 | When many people see birds cleaning their feathers, . But, in reality, what they are doing is maintaining their wings, the instruments that they depend on for safe flight. If a bird's wings are not in perfect condition, the bird either won't be able to fly or won't be able to control its flight. That is why after a long flight and even throughout the day, you will see them cleaning their feathers. Most birds, if they get a chance, will take a bath at least once a day. They do this to get rid of the dust that has accumulated in their feathers throughout their flight s during the day. In dry or desert areas, birds will not always be able to find water in which to bath, but they still need to clean their feathers. What many birds will do is to take dust baths. They will roll around in dust until it covers their feathers. They will stand up, shaking the dust out, and then clean their feathers with their beaks as usual. Baths are important for another reason. During the course of the day and night, many parasites are attracted to birds. Bugs, mites, fleas and so on will try to reach birds and suck from their blood. Daily baths help to keep the parasites to a minimum. Some birds, especially those that spend a lot of time in or around water, have skin glands that produce oil. After bathing, these birds will squeeze the glands to spread the oil over their wings to keep them free of water. If you are a bird lover and have bird houses in your yard, it can be good to go to the extra step, providing a bird bath. Once the birds in your neighborhood discover it, you will be surprised at how popular it becomes as they periodically stop by to take their daily bath.

mmlu_train_6376 | In my first week as a graduate student at Cambridge University in 1964 I met with a fellow student, two years ahead of me in his studies; he was unsteady on his feet and spoke with great difficulty. This was Stephen Hawking. I learned that he had a bad disease and might not live long enough even to finish his PhD degree. But, amazingly, he has reached the age of 73. Even mere survival would have been a medical miracle, but of course, he didn't merely survive. He has become arguably the most famous scientist in the world for his brilliant research, for his bestselling books, and, above all, for his astonishing victory over hardship. Stephen received his "death sentence" in 1964, when I thought it was hard for him to go on with his study. Stephen went from Albans School to Oxford University. He was said to be a "lazy" undergraduate, but his brilliance earned him a first-class degree, an "entry ticket" to a research career in Cambridge and a uniquely inspiring achievement. Within a few years of the burst of his disease he was wheelchair-bound, and his speech was so unclear that it could only be understood by those who knew him well. But his scientific career went from strength to strength: he quickly came up with a series of insights into the nature of black holes (then a very new idea) and how the universe began. In 1974 he was elected to the Royal Society at the exceptionally early age of 32. The great advances in science generally involve discovering a link between phenomena that were previously conceptually unconnected -- for instance, Isaac Newton realized that the force making an apple fall to earth was the same as the force that holds the moon and planets in their orbits. Stephen's revolutionary idea about a link between gravity and quantum theory has still not been tested. However, it has been hugely influential; indeed, one of the main achievements of string theory has been to confirm and build on his idea. He has undoubtedly done more than anyone else since Einstein to improve our knowledge of gravity and he is one of the top-ten living theoretical physicists. What can we learn from the text? | [

mmlu_train_22964 | Contrary to people's previous knowledge, it's food shortage not dietary preference that motivates birds to migrate thousands of miles back and forth between breeding and nonbreeding areas each year, a new research shows. "It's not whether you eat insects,fruits or candy bars or where you eat them that counts,but how reliable that daytoday food source is," said the study leader W.Alice Boyle of the University of Arizona. To figure out the underlying pressure that drives some birds to leave home for the season,Boyle examined 379 related species of New World flycatchers and compared their sizes,food types, habitats, migratory behaviors and whether or not they fed in flocks. To compare the birds,the researchers constructed a "supertree" showing the exact evolutionary relationships among different species. A computer analysis then determined whether a particular species was migratory because it ran in the "family" or whether something in the bird's environment was forcing it to leave each season.Boyle and her colleagues found that food shortage was the number one issue that predicted a species' migratory behavior. "Food availability is the underlying pressure, not diet and habitat," Boyle said. An alternative strategy that the birds use to handle food shortage is to hunt in flocks, since a group is more likely to find a new source of food than an individual. "If you suffer from food shortage, you have two options," Boyle said."You can either hunt with other birds or you can migrate." Birds were thought to migrate in order to _ . | [

mmlu_train_83853 | It is reported by Chinese Xinhua News that students waste more food than the national average. So the campaign on school food waste is getting popular across the country. The move is part of a national campaign started by students at different schools. At East China University of Science, students who finish their food in the school dining hall get a special card when they return their plates after meals. Students can collect cards and exchange them for small gifts, such as books, schoolbags, magazines and umbrellas. "It's been such a surprise," said Liang Zhaoyun, 19, a student in Shanghai. "It has given us one more motivation to eat up our food." "The purpose of the campaign is not only to encourage students to finish their food. We hope it can also teach students to choose a more environment-friendly and healthy lifestyle," said Tao Siliang from University of Traditional Chinese Medicine. Other schools also pay attention to the quantity of food. At Nanjing No.9 Middle School, rice is divided into three different-sized bowls that students can choose from according to their own need. "It's great because I can try different dishes at half price and don't waste so much food," said Fan Peng, 15, a student from this middle school. What if you really can't finish all your food? At Changchun Normal College, they provide a take-away service. "If you can't finish all your food, you can get a box to take the left food home. Even if you feed the cat, it's not wasted," said Zhou Zeyong, a student who learns Chinese education. "I'm happy that we've cut down waste since joining the school 'eat-up' meeting. But some food is poorly cooked, meaning that students are not willing to finish it all. Some schools have taken note of this. So if we hope students try to waste less food, we should also improve the service and keep an eye on the meal quality on weekdays at school.

mmlu_train_18286 | Every hour spent in watching TV, DVDs and videos as an adult reduces life expectancy by almost 22 minutes, a study suggests. And viewing TV for an average of six hours a day can cut short your life by five years. The research claims that a sedentary lifestyle is as bad for health as smoking and obesity, because of the dangers caused by inactivity and the greater opportunities _ offers for unhealthy eating. The academics conducting the study set out to calculate the overall risk to life expectancy from watching television. Their research involved more than 11,000 people over the age of 25. Writing in the British Journal of Sports Medicine, they concluded. "TV viewing time may be associated with a loss of life, which is similar to other major chronic disease risk factors such as physical inactivity and obesity." The researchers, from the University of Queensland, used information from the Australian Diabetes, Obesity and Lifestyle Study, together with population and death rate data. But they said: "Although we used Australian data, the effects in other industrialized and developing countries are likely to be similar, considering the large amounts of time spent watching TV and similarities in disease patterns." In the United Kingdom, the average amount of time spent watching TV is four hours a day, compared with five hours in the United States. Earlier this year, a separate study suggested the risk of developing type 2 diabetes and heart disease, or dying early, rises by as much as 20 percent after just two hours a day in front of the box. England's Chief Medical Officer, Sally Davies, said: "Physical activity offers huge benefits and these studies back what we already know - that a sedentary lifestyle carries additional risks.

mmlu_train_10780 | Bicycles, roller skates and skateboards are dangerous. I still have scars on my knees from my childhood run-ins with various wheeled devices. Admittedly, I was a foolish kid, but I'm glad I didn't spend my childhood trapped indoors to protect me from any injury. "That which does not kill us makes us stronger." But parents can't handle it when teenagers put this theory into practice. And now technology has become the new field for the age-old battle between adults and their freedom-seeking kids. Locked indoors, unable to get on their bicycles and hang out with their friends, teens have turned to social media and their mobile phones to gossip and socialize with their friends. What they do online often mirrors what they might otherwise do if their mobility weren't so heavily restricted in the age of helicopter parenting. Social media and smartphones have become so popular in recent years because teens need a place to call their own. They want the freedom to explore their identity and the world around them. Instead of climbing out of windows, they jump online. As teens have moved online, parents have projected their fears onto the Internet, imagining all the potential dangers that youth might face. Rather than helping teens develop strategies to deal with public life and the potential risks of interacting with others, fearful parents have focused on tracking, monitoring and blocking. These approaches don't help teens develop the skills they need to manage complex social situations. "Protecting" kids may feel like the right thing to do, but it denies teens the chances of learning as they come of age in a technology-soaked world. The key to helping youth in the modern digital life isn't more restrictions. It's freedom -- plus communication. Urban theorist Jane Jacobs used to argue that the safest neighborhoods were those where communities collectively took interest in and paid attention to what happened on the streets. Safety didn't come from surveillance cameras or keeping everyone indoors but from a collective willingness to watch out for one another and be present as people struggled. The same is true online. What makes the digital street safe is when teens and adults collectively agree to open their eyes and pay attention, communicate and work together to deal with difficult situations. Teens need the freedom to wander the digital street, but they also need to know that caring adults are behind them and supporting them wherever they go. The first step is to turn off the tracking software. Then ask your kids what they're doing when they're online -- and why it's so important to them. When he was a child, the writer _ . | [

However, you can also find many weather signs among wildlife, because of their highly developed senses. Drops in air pressure produce an effect on small animals in many ways. Mice and deer are good weather indicators. People who spend a lot of time outdoors have observed that, before a storm, field mice come out of their holes and run around, Deer leave high ground and come down from the mountains. Birds are especially good weather indicators because they also show the effect of a pressure drop in many ways. For example, some birds become irritable and quarrelsome and will fight over a piece of bread. Other birds chirp and sing just before a storm. It seems they know they won't get another chance for an hour or two. Birds also seek safe places before a storm, You will sometimes see birds settling in trees or gathering together on a wire close to a building.

mmlu_train_62494 | BEIJING - By the end of 2011 China-made supercomputers will say goodbye to foreign microchips and start using their own "Chinese core ", according to one of the country's leading scientists, Hu Weiwu. Hu told reporters on Saturday that the "Dawning 6000" supercomputer, developed by the Institute of Computing Technology of CAS and the Dawning Information Industry Company (DIIC), will adopt Loongson microchips for the first time as its core parts. It will have a computing speed of more than 1,000 trillion operations a second. Making supercomputers with Chinese microchips is one of the nation's major science and technology projects. Three organizations - the Institute of Computing Technology of CAS, Jiangnan Institute of Computing Technology and the National University of Defense Technology (NUDT) - have their own supercomputer projects. According to their schedules, all three institutions will need to meet the target of using domestically developed microchips by the end of this year. Hu said the new supercomputer will use fewer than 10,000 Loongson microchips, and will also be more energy-efficient. Tianhe-1A, developed by NUDT in Hunan's provincial capital Changsha, is the fastest supercomputer in the world. However, Tianhe-1A largely runs on 14,336 CPUs made by Intel, and 7,186 GPUs (processing units) from Nvidia, two US chip-makers. Hu said there will be difficulties ahead as there is little _ equipment specially developed for these supercomputers. "We have enough supercomputers in China but still can't make full use of them," He said. Hu added that although the China-made CPUs have improved since they were first produced in 2002, they have a long way to go to compete with US chip-makers such as Intel.

mmlu_train_49563 | Stephen Hawking knew what he wanted to do by the time he was eight years old. His parents lived in London where his father was researching medicine. He did not want to follow his father as his parents hoped. Mathematics was not available at University College, so he did physics instead. Stephen was interested in studying the universe. When he was 21, however, he was told that he had ALS --an incurable nerve disease, which affects walking, speaking, breathing, swallowing, and many other things. The doctors predicted that he had only a few years to live, but he didn't die. Instead, as his physical condition became worse, Hawking became more well-known in scientific circles. Hawking himself said that his disease was a big reason why he focused his attention on what turned out to be his real strength: theoretical research. "What the doctors said made me determine to get the most from life, and life was no longer boring for me," Hawking says today, speaking from his wheelchair through a computer. In 1988, Stephen Hawking published a book called A Brief History of Time. The book tries to explain many of Hawking's physical and mathematical ideas and calculations without using maths. The book became a best-seller. His later books are Black Holes and Baby Universes and Other Essays and most recently in 2001, The Universe in a Nutshell. Of the three, the first one was made into a film in 1991. Hawking says, "Nowadays, muscle power is out of date. What we need is mind power --and disabled people are as good at that as anyone else."

In 1930, Neumann visited Princeton University for a year and then became a professor there.His first book was published in 1932.In 1933, the Institute for Advanced Study was formed, and he became one of the 6 full-time people in the School of Mathematics (Einstein was one of the others). World War II hugely changed Neumann's areas of interest.Until 1940 he had been a great pure mathematician.During and after the war, he became one of the best mathematicians who put mathematics theories into practice.During the last part of the war he became interested in computing machines and made several contributions.After the war, Neumann continued his work with computers, and was generally very active in government service.He received many awards, was president of American Mathematical Society and was a member of the Atomic Energy Commission.He died in 1957 of cancer.

mmlu_train_23463 | Almost anyone who has read a travel brochure about Africa has heard of a story ----- that elephants can get drunk by eating the fermented marula fruit rotting on the ground. Books have even been written to prove the truth of the phenomenon. But a study published in the journalPhysiological and Biochemical Zoologytells a very different story. Steve Morris, a biologist at the University of Bristol in England and an author of the study, says there is nothing in the biology of either the African elephant or the marula fruit to support the stories. Morris says, "People just want to believe in drunken elephants." The marula tree, a member of the same family as the mango , grows widely in Africa. Its sweet, yellow fruit is used for making jam, wine and beer. "The first mistake of the drunken-elephant theory is that it's unlikely that an elephant would eat the fruit if it were rotten," Morris says. "Elephants eat the fruit right off the tree, not when it's rotten on the ground," he explains. Other experts add that if an elephant were to eat the fruit on the ground, it wouldn't wait for the fruit to ferment. Michelle Gadd, an African wildlife specialist, says that elephants and many other animals, including birds and monkeys, are too fond of marula fruit to let it rot. If fermented fruit on the ground is out of the question, so is the concept that the fruit could ferment in the stomach of elephants, according to the study authors. Food takes between 12 and 46 hours to pass through an elephant's digestive system, the authors point out, which is not enough for the fruit to ferment. Supposing that _ happened, it's still highly improbable that the food would produce enough alcohol to make an elephant drunk. Through calculations of body weight, elephant digestion rates, and other factors, the authors conclude that it would take about 1.9 litres of alcohol to make an elephant drunk.

mmlu_train_8778 | Why Laughter Matters Although most people believe that laughter is one of the nature's great treatments for a whole range of mental and physical diseases, it is still a serious scientific subject that researchers are trying to figure out. "Laughter above all else is a social thing," says Baltimore neuroscientist, Robert Provine, who has studied laughter for decades. "All laughter groups laugh 'ha-ha-ha' basically the same way. Whether you speak Mandarin, French or English, everyone will understand laughter. There is a pattern generator in our brain that produces this sound." Laughing is our first way of communicating. Babies laugh long before they speak. No one teaches them how to laugh. They just do. People may laugh at a prank on April Fools' day. But surprisingly, only 10 to 15 percent of laughter is the result of someone making a joke. Laughter is mostly about social responses rather to a joke. Deaf people laugh without hearing and people on cell phones laugh without seeing, showing that laughter isn't dependent on single sense but on social interactions. And laughter is not just a people thing. Chimps tickle each other and even laugh when another chimp pretends to tickle them. Jaak Panksepp, a Bowling Green University Psychology professor, studies rats that laugh when he tickles them. It turns out rats love to be tickled--they return again and again to the hands of researchers tickling them. By studying rats, scientists can figure out what's going on in the brain during laughter. Northwestern University biomedical engineering professor, Jeffrey Burgdorf has found that laughter in rats produces a chemical that acts as an antidepressant . He thinks the same thing probably happens in humans, too. This would give doctors a new chemical target to develop drugs that can fight depression. Even so, laughter itself has not been proved to be the best medicine, experts said. Margaret Stuber, a professor at University of California, studied whether laugher helped patients. She found that distraction and mood improvement helped, but she could not find a benefit of laughter alone. "No study has shown that laughter produces a direct health benefit," Provine said, largely because it's hard to separate laughter from just feeling good. But he thinks it doesn't really matter: "Isn't the fact that laughter feels good when you do it enough?" The most important finding of Robert Provine's research is that _ . | [

mmlu_train_70992 | Peter is a sixth-grader at Woodland Primary School. He is only 12 years old but has been smoking for three years. John, 15, is a Junior 2 student at Woodland Secondary School. He began smoking four years ago. "Smoking is part of my life," John said. Peter and John are not those boys' real names. But their problem, smoking, is a very real problem. In many countries, smoking is becoming a bigger problem for young people. Most smokers start in their teens or earlier. A study of 8,000 London students shows that smoking is a problem for many British kids. More than 21% of middle school students and 6% of primary school pupils said they smoked. "If young people start smoking early, it will be very hard for them to give up later on," said a professor. Every year, about four million people die because of smoking. And if people keep smoking that number will go up to about ten million a year by 2030 the World Health Organization (WTO) says. So we have to learn and tell others about dangers of smoking. ,.

mmlu_train_64958 | AC/DC have postponed their US tour after singer Brian Johnson was warned by doctors that he was at risk of "total hearing loss". This is unsurprising, given the decades that the Australian band has been pumping out the hard rock decibels . But deafness isn't only a concern for rock musicians. In recent years it has become clear that anyone around music a lot has reason to be equally worried. When exposed to music, risk to hearing arises from a combination of how loud the sound is and how long you're exposed to it. If you visit a nightclub that is thumping out music on the dance floor at 100 dB, then after only 10-15 minutes the exposure is potentially damaging. In a quieter part of the club, but where the music is still loud enough that you have to shout at your friends, then you could be there for a couple of hours before having to worry about your hearing. Of course music frequently exceeds 80-85 dB, but what counts most in assessing the risk to hearing is the average exposure. Exposure to high noise levels often causes temporary deafness - something many people have experienced after going to a nightclub. While hearing usually recovers after a few hours or days, repeated loud exposure leads to permanent hearing damage. Initially, this damage is subtle and unlikely to be noticed by the listener. Problems only becomes significant in middle age when the noise-induced hearing loss combines with the natural loss of hearing due to ageing. Improved technology means that the number of musicians having to give up performing could decrease, but student musicians need to be educated about the dangers of noise-caused hearing loss. The increasing use of headphones will also work against this - for musicians and everyone else. Unless people are careful with the volume level on their portable music players, hearing loss caused by music will increase.

"They spend about thirteen hours every week online,"said Qian Hulin,an Internet expert . Doctor Song in Beijing Xuanwu Hospital said about 14% of Chinese netizens who are teens often lasted over ten hours to play online games. The main reasons why teenagers surf the Web are to search for information,to communicate with others and to have fun. On the Internet,teenagers can find out almost everything. And surfing the Web can help students with their homework and widen their knowledge. Li Dong,a teacher at No. 41 Middle School in Shijiazhuang,likes her students to use the Internet.

mmlu_train_61892 | "Keep out or I'll chase you out! This is my property!" You hear this every spring. It is a long musical sound --- a bird song! Birds use their songs to communicate different messages to one another. People who study bird sounds are learning their meanings. Usually it is the male that sings. Early in spring he sings to say that he has picked out a piece of property. He sings to attract a female of his same kind. Together they will raise a family in his territory . He sings to tell all other birds of his kind to keep out. Each kind of bird has its own type of song. Cardinals sing something that sounds a little like "What cheer, cheer, cheer." Towhees sing, "Drink your tea." Most of the time, birds pay attention only to the songs of birds of their own kind. Cardinals answer cardinals, and song sparrows answer song sparrows. A cardinal knows that a song sparrow will not try to steal its mate. So you can see one reason why a cardinal may chase away another cardinal but will not bother a song sparrow. Most different kinds of birds eat different things. To find enough to eat, a bird needs a big piece of land to search in. Many kinds of birds have some ways of dividing up the land into territories. Song sparrows, cardinals ovenbirds, and white-throated sparrows are some of the birds that have territorial systems. Especially in early spring, birds work out the boundaries between their territories by singing "keep out" threats and by chasing and fighting each other. The birds continue singing to tell females that they have set up territories. Neighboring birds seem to agree that there are make believe fences between their pieces of property. Then they do not have to waste energy chasing each other instead of taking care of their young. Scientists guessed that some birds could recognize their neighbors by small differences in their songs. Two scientists who studied white-throated sparrows found that these birds can even tell the difference between songs of individual birds of their own kind. White-throated sparrows have songs that seem to say "I'm your neighbor" or "I'm a stranger" or "I'm your neighbor to the west." Other kinds of birds could tell neighbors from strangers by their songs, too. What is the article mainly about? | [

mmlu_train_20574 | We can express our feelings and needs by using body language. Cats can do that too. The ways that cats use their tails to show their feelings and needs are interesting. Unlike dogs, which generally wave their tails to express good feelings, cats use their tails to send a lot of signals. When a cat waves its tail strongly from side to side, it may be a sign for us to leave it alone, or we may get scrathed . Throwing a little toy for the cat to play with can get it relaxed. When a cat holds its tail upwards with a slight move, it means the animal is very happy to see its owner. We all like to cuddle inside our bed, and cats do that thing, too. Much as little children like to wrap (......) their arms around their Teddy Bears, cats like to wrap their own tails around their bodies to get a sense of safety while asleep. If we notice a cat sleeping in such a position, we should not break its peace. Usually the tip of the cat's tail doesn't draw our attention. But its particular position may also show the cat's feelings. For example, a cat holding the tip of its tail pointed downwards may try to say that it is not feeling comfortable. So at this point, the cat not only feels angry, but also unsafe. This may again be a sign for us not to upset the cat in any way.

mmlu_train_26349 | The scene in the Hollywood movie The Day After Tomorrow, when global warming could soon turn the global climate into a new ice age, may never occur, according to a new research. The next ice age could be 15,000 years away, say European scientists who last month announced a continuous record of 740,000 years of climate data obtained from the Antarctic ice. Scientists from 10 nations have now almost completely drilled through a 3,000-meter depth of ice high in the Antarctic mainland. They figure out that the area, where summer temperatures can fall to - 40degC, has at least 900,000 years of snowfalls, kept as neatly as the growth rings of a tree. And the ice and air caught in each layer have begun to answer questions about the climates in the past.. The results show that there have been eight ice ages in the past 740, 000 years and eight warmer periods. And by comparing the pattern of global conditions today with those of the past, the researchers reported in Nature that the present warm period could last another 15, 000 years. Research suggests that there is a very close connection between greenhouse gas levels and global average temperatures. It also shows that carbon dioxide levels are the highest for at least 440,000 years. "If people say to you: 'the greenhouse effect is a good thing because we would go into an ice age otherwise,' our data say no, a new ice age is not hanging over our heads," said Eric Wolff from the British Antarctic Survey. "Now we have eight examples of how the climate goes in and out of ice ages... and you can learn what the rules are that go into the climate models that tell us about the future." Scientists found that whenever temperatures rose in the frozen record, so did carbon dioxide level. "In 440,000 years we have never seen greenhouse gas get as thick as it is today," said Dr Wolff.

There was no doubt that I had a great deal of energy, and therefore I was always talking with my classmates and not paying attention to the lessons, which my teacher _ to see. If you don't believe me, the comments on my report cards every year can tell the story. In my third year in elementary school, my teacher wrote, " Neil should tend to have a more serious attitude towards his schoolwork." And in my fifth year in elementary school, my teacher wrote, " Neil is not a bit strict with his work, his compositions as well as his notebook and so on. He has to be encouraged and urged by his parents or teachers." After only a few months, my sixth-grade teacher wrote, " Less social involvement and more academic diligence is in order." Later that same school year, my sixth-grade teacher noticed that all my book reports were about the universe. Knowing that I had a lot of extra energy, she recommended that I should take advanced after-school classes about the universe at the Hayden Planetarium. From then on, my love of the universe became stronger and stronger. Instead of killing my time in class, I focused my extra energy on the subject that would be bound to become my career.

mmlu_train_59313 | Avalanches are one of those natural disasters that can cause great damage and only Mother Nature knows when and where they are going to occur. Even with modern technology it is still impossible to know exactly when or where one is going to occur. Mountain climbers are wise to be careful, as avalanches kill many of them each year. The physics of how and why an avalanche occurs is complex. There are times of higher probability. During the year, the transition( from winter to spring will cause some snow and ice to melt, which may trigger avalanches. Also at daybreak there is a higher probability due to the temperature change . While climbers hike up slopes, some distance between the climbers should be kept. If an avalanche occurs, then there will be fewer lives lost and a higher probability that someone will be able to seek help. Since an accident is more likely to happen when a top layer of snow is loose, avoid areas where heavy snow or rain has recently occurred. Try to choose areas that you are familiar with and stay in areas with rocks, bushes and trees. Trees and bushes allow snow to pile up and keep the layers stable. If an avalanche occurs, trees will take the impact of the snow, so there is a better chance of being safe. Climbers must pay attention to the degree of the slope. Avalanches won't occur on level ground and there is little snowfall on very steep areas. The greatest danger is in areas where the slope is between 25 and 40 degrees. Remember that, if you get stuck in an avalanche, there is no car hire available to take you to the nearest airport. Why is there a higher probability that an avalanche occurs at daybreak? | [

mmlu_train_50521 | Regularly staying late at the office significantly increases the risk of having a stroke or heart attack, researchers have found, working just an hour extra each day pushes up stroke risk by 10 per cent, according to a huge review of working patterns. And people who work an extra three hours a day--or 55 hours a week--are 33 per cent more likely to have a stroke, the scientists found. The research, published in the Lancet medical journal, is based on health records of more than 500, 000 people across Europe, the US and Australia. Scientists led by University College London warned that people who work longer hours tend to do less exercise, sit at a computer for hours at a time and drink more than people with a better work-life balance. Repeated stress may also be to blame for greater health problems, the scientists think. They looked at the combined result of 17 previous studies, in which 529, 000 people were tracked over an average of seven years. Experts stressed that the study had only found a link between hours worked and heart problems---it had not proved what had actually caused each death. But they warned people to take note of the findings. Dr Tim Chico, consultant cardiologist at Sheffield Teaching Hospitals, said "For many people, reducing their working hours would be difficult or impossible, and this study does not show that it would reduce the risk of stroke." Most of us could reduce the amount of time we spend sitting down, increase our physical activity and improve our diet while working and this might be more important the more time we spend at work.

mmlu_train_76723 | There is an old saying in English, "Laughter is the best medicine". Until recently, few people took the saying very seriously. Now however, doctors have begun to study laughter and the effects it has on the human body. They have found evidence that laughter really can improve people's health. Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their heart rate, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise. It increases blood pressure, the heart rate and the rate of breathing. It also works several groups of muscles in the face, the stomach and even the feet. If laughter exercises the body, it must be helpful. Other tests have shown that laughter appears to make the effect of pain on the body less. In one experiment doctors produced pain in groups of students who listened to different radio programs. The group which could bear the pain for the longest time was the group which listened to a funny program. The reason why laughter can make pain less seems to be that it helps to produce endorphins in the brain. These are natural chemicals which make both stress and pain less. There is also some evidence to suggest that laughter helps the body's immune system that is the system which fights infection . In an experiment, one group of students watched a funny video while another group served as the control group -- in other words, a group with which to compare the first group. Doctors checked the blood of the students in both groups and found that the people in the group that watched the video had an increase in the activity of their white blood cells that is the cells which fight infection. As a result of these discoveries, some doctors and psychiatrists in the United States now hold laughter clinics, in which they try to improve their patients' condition by encouraging them to laugh. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce good effects similar to those caused by laughter.
