mmlu | Question:
Koalas are found only in prefix = st1 /Australia. Even if called koala bear, this animal has nothing to do with the actual bear; it is not even a mammal , but a marsupial , like the kangaroo. Its closest living s are the wombats . A koala is about 60-80cm long and weighs 5-14kg. The name "koala" means "no drink", and refers to the koala's ability to go for days without water. Koalas get the water content they need from the eucalyptus leaves on which they feed. The koala is the only mammal with a digestive system that can feed only on eucalyptus leaves--incidentally, these leaves are highly poisonous if eaten by humans. One individual consumes about 5kg of eucalyptus leaves daily and it may never drink water! The koala is a _ mammal. They prefer to move around just after sunset, spending daytime sleeping in the fork of a tree. A koala spends sleeping 75% of its time. The eucalyptus leaves they eat are rich in fiber and poor in proteins and fats. The adult must detoxify leaves with energy expense, while fiber is hard to break down. Because of this poor diet, koalas save energy by sleeping most of the day, while their movements are very slow. Koalas only have one young per year. In summer, baby koalas are born about a month after mating. The female takes it with her mouth and places it into her poach. In 6 months, the young can get out and feed on leaves. There are probably around 2,000 to 8,000 wild koalas in Australiaat present. The extremely fine gray fur is the reason why koala has been heavily hunted in the past. Koalas are killed every year by dogs, cats, dingoes, eagles and owls. They also die of disease and accidents. Why does the koala spend most of its time sleeping?
Choices:
A. To escape from natural enemies.
B. To save its energy.
C. To protect itself from the sun.
D. To detoxify eucalyptus leaves. | B |

"I'm a little worried about my future."said Dustin Hoffman in The Graduate.He should be so lucky.All he had to worry about was whether to have an affair with Mrs. Robinson.In the sixties,that was the total sum of post-graduation anxiety. Hoffman's modem peers are not so fortunate.The Mrs. Robinsons aren't sitting around at home any more.They are out in the workplace,doing the high-powered jobs the graduates want,but cannot get.For those fresh out of university,desperate for work but unable to get it,there is a big imbalance between supply and demand.And there is no narrowing of the gap in sight. Parents feel as badly let down as the young people themselves.Middle-class families see their graduate offspring on the dole queue and wonder why they bothered paying school fees.Working-class families feel an even keener sense of disappointment.For many such families,getting a child into university was the fulfillment of a lifelong dream.It was proof that they were living in a dynamic,economically successful country.That dream does not seem so rosy now.Graduate unemployment is not,ultimately,a political problem.Job-creation for graduates is very low down in the government's schedule.If David Cameron's Conservatives had a brilliant idea for guaranteeing every graduate a well-paid job,they would have presented it by now.It is a social problem,though a more deep-seated social problem than people perhaps realize. The main purpose of the passage is to _ .

A. criticize the government
B. present a current severe situation
C. publicize a movie
D. display the success of the country | B |

mmlu | Question:
Do you know anything about the history of weather? Don't look at the sky. Don't look for old weather reports. Looking at the tree rings is more important. Correct weather reports date back only one century, but some trees can provide an exact record of weather even further back. It is natural that a tree would grow best in a climate with plenty of sunlight and rainfall. It is also expected that little sunlight or rainfall would reduce the growth of a tree. The change from a favorable to an unfavorable climate can be found out by the reading pattern of rings in a tree trunk. To find out the weather of ten years ago, you can count the rings of a tree trunk from the outside to the inside. If the tenth ring is far from the other rings, then it is certain that plenty of sunny and rainy weather occurred. If the rings are close together, then the climate was bad for the tree. Studying trees is important not only for the history of weather, but also for the history of man. In an area of New Mexico you can find only sand -- no trees or people. However, many centuries ago a large population lived there. They left suddenly. Why? A scientist studied the pattern of the rings of dead trees that had grown there. He made up his mind that the people had to leave because they had cut down all the trees. Trees were necessary to make fires and buildings. So, after the people destroyed the trees, they had to move. In this example studying tree rings uncovered an exciting fact about the history of man. By studying the rings of dead trees in an area of New Mexico, the scientist found _ .
Choices:
A. what the people had to eat
B. where the people had to go
C. why the people had to leave
D. how the people left | C |
mmlu | Question:
What doomed the Titanic is well known, at least in outline. On a moonless night of April 15, 1912, the ship hit an iceberg in the North Atlantic ,with 1,500 lives lost. A century later many people presented new theories to explain the real reason for the disaster. Now two new studies argue that rare states of nature played major roles in the disaster. The first says Earth's nearness to the Moon and the Sun -- a proximity not matched in more than 1,000 years -- resulted in record tides that help explain why the Titanic met with so much ice, including the fatal iceberg. Recently, a team of researchers found an apparent explanation in the heavens. They discovered that Earth had come unusually close to the Sun and Moon that winter, enhancing their gravitational pulls on the ocean and producing record tides. The rare orbits took place between December 1911 and February 1912 -- about two months before the disaster came about. The researchers suggest that the high tides refloated masses of icebergs traditionally stuck along the coastlines of Labrador and Newfoundland and sent them adrift into the North Atlantic shipping lanes. And a second, put forward by a Titanic historian from Britain, contends that the icy waters created ideal conditions for an unusual type of mirage that hid icebergs from lookouts whose duty was to watch carefully for danger ahead and confused a nearby ship as to the liner's identity, delaying rescue efforts for hours. Most people know mirages as natural phenomena caused when hot air near the Earth's surface bends light rays upward. In a desert, the effect prompts lost travelers to mistake patches of blue sky for pools of water. But another kind of mirage occurs when cold air bends light rays downward. In that case, observers can see objects and settings far over the horizon. The images often undergo quick distortions -- not unlike the wavy reflections in a funhouse mirror. Now, scholars of the Titanic are debating these new theories. Some have different opinions on it. Over all, though, many experts are applauding the fresh perspectives. (words:353) This passage is organized generally in the pattern of _ .

mmlu | Question:
Though chopsticks are used in many Asian countries, they have their beginning in China. Chinese history says that the Chinese had chopsticks as far as the Xia Dynasty (about 4, 00 years ago). In the Spring and Autumn Period copper and iron chopsticks appeared. With the Han Dynasty lacquered chopsticks came, followed by gold and silver chopsticks still later. Today we have chopsticks made of plastics. The most expensive are made of part of tusks of elephants and hard green stone. Chopsticks tell Chinese tradition in their way. In ancient times the rich used hard green stone or gold chop-sticks to show their wealth . In history many kings used silver chopsticks to take their food to see if it was poisonous . It was said that if it was, the silver chopsticks would turn colour. Chopsticks are traditionally given to a daughter when she marries to show that they should have a son very soon, for "Chopsticks" in Chinese is pronounced like "quick a son"! Tianzhu chopsticks from Hangzhou, wooden chopsticks from Shanyang of Shanxi Province, and Beijing's chopsticks are well-known. Many westerners, businessmen, tourists put aside their knives and forks in favour of chopsticks in China. Chopsticks appeared in the old Chinese story: an old man teaches his sons a lesson by showing how he could easily break a single chopstick but not a number of them. In China, chopsticks are connected with good luck. So on the country's New Year's Eve many families will lay out new chopsticks at dinners as a way of making requests for luck. Copper and iron chopsticks appeared in _ .

mmlu | Question:
Have you ever wondered? 1. Why do airplanes take longer to fly west than east? It can take five hours to go west-east from New York (NY) to London but seven hours to travel east-west from London to NY. The reason for the difference is an atmospheric phenomenon known as the jet stream. The jet stream is a very high altitude wind which always blows from the west to the east across the Atlantic. The planes moving at a constant air speed thus go faster in the west-east direction when they are moving with the wind than in the opposite direction. 2. What would happen if the gravity on Earth was suddenly turned off? Supposing we could magically turn off gravity. Would buildings and other structures float away? What happened would depend on how strongly the things were attached to the Earth. The Earth is moving at quite a speed, moving at over a thousand miles per hour. If you turn something around your head on a string , it goes around in a circle until you let go of the string. Then it flies off in a straight line. 'Switching off' gravity would be like letting go of the string. Things not attached to the Earth would fly off in a straight line. People in buildings would suddenly _ upwards at a great speed until they hit the ceiling. Most things outside would fly off into space. Where can we most probably read this text?

mmlu | Question:
The expression "Go for it!" is a way of encouraging someone to try something. "Go for it!" means you should not worry about failure or be too careful. You should take a chance, be brave, and act firmly. "Go for it!" gets name from football. Not football as it is played in most countries such as England, Egypt or Japan, but the kind of football played in the United States and Canada. One of the most exciting times in football comes when a team has failed, after three attempts, to move the ball forward ten yards. The team must make a critical decision. The conservative choice is to kick the ball and accept temporary defeat in order to gain a good position for your team the next time it gets the ball. The more exciting choice, however, is to try a fourth and final time to gain the remaining yards needed. In the nineteen eighties, people began using this expression in many kinds of situations to encourage someone to act bravely. There is no guarantee that the action you "Go for it!" will succeed. But that is the chance you take when you decide to go for it. You put your fears behind. You choose courage over safety. You hold your breath and go for it. In which of the following situations should we use the expression nowadays?
Choices:
A. We decide to avoid trouble or danger for the future.
B. We try to improve our English for better education.
C. We need to make a quick decision at the last moment.
D. We have to make a choice between success and failure. | C |

Science has a lot of uses. It can reveal laws of nature, cure diseases, make bombs, and help bridges to stand up. Indeed science is so good at what it does that there's always a temptation to drag it into problems where it may not be helpful. David Brooks, author ofThe Social Animal, The Hidden Sources of Love, Character, and Achievement, appears to be the latest in a long line of writers who have failed to resist the temptation. Brooks gained fame for several books. His latest bookThe Social Animal, however, is more ambitious and serious than his earlier books. It is an attempt to deal with a set of weighty topics. The book focuses on big questions: What has science revealed about human nature? What are the sources of character? And why are some people happy and successful while others aren't? To answer these questions, Brooks surveys a wide range of subjects. Because of this, you might expect the book to cover a variety of facts. But Brooks has structured his book in an unusual, and perhaps unfortunate way. Instead of introducing scientific theories, he tells a story, within which he tries to make his points, perhaps in order to keep the reader's attention. So as Harold and Erica, the hero and heroine in his story, live through childhood, we hear about the science of child development and as they begin to date we hear about the theory of sexual attraction. Brooks carries this through to the death of one of his characters. On the whole, Brooks's story is acceptable if uninspired. As one would expect, his writing is mostly clear and, to be fair, some chapters stand out above the rest. I enjoyed, for instance, the chapter in which Harold discovers how to think on his own. While Harold and Erica are certainly not strong characters, the more serious problems withThe Social Animallie elsewhere. These problems partly involve Brooks's attempt to translate his tale into science. The author mentions the functions of science at the beginning of the passage to _ .
Choices:
A. show the value of Brooks's new book
B. show where science can be applied
C. remind the reader of the importance of science
D. explain why many writers use science in their works | D |

Edward Sims was born in 1892. He was the fifth child and only son of Herbert and Dora Sims. Herbert was a blacksmith , and had a thriving trade making horseshoes. He was determined that his first-born son would follow him into the blacksmith. For this reason, Edward had to leave school at the age of 12,and worked with his father. However, Edward was _ a blacksmith. Although he has an athletic body, he didn't have strong arms like his father, and he felt dizzy in the heat of the smithy. When he tried to find alternative employment, he found it difficult because he had never learnt to read or write. One day, he went for an interview at a solictior's office. The job was a runner, taking documents from the office to other offices in the city. The solicitor was pleased to see that Edward was physically fit, but when he discovered that the young man couldn't read or write, he decided against employing him. "How can you deliver documents to other offices," he asked, "if you can't read the addresses on them?" Bitterly disappointed, Edward left the building and went to wait for a tram to take him back to the suburb where his father's smithy was. Next to the bus stop, a man was selling newspapers from a stand . "Excuse me, son?" he said. "Would you look after my stand for a moment?" For the next 20 minutes, Edward sold newspapers, lots of them. When the man came back, he was so delighted with his new assistant's honesty, that he offered him a job. Edward took it immediately. In the next few months, the two men progressed from working on newspaper stands to selling newspapers, tobacco,confectionery and other goods in a shop. Then they opened a second shop, and a third. Eventually, they had a chain of 25 shops in three cities. Edward became very rich, so he employed a tutor to teach him to read and write. The tutor was amazed at what Edward had achieved. "Imagine what you could do if you'd been able to read and write when you were younger!" he said. "Yes!" said Edward. "I could have run myself to exhaustion delivering documents for a solicitor!" When Edward applied for the job as a runner for a solicitor, _ .

mmlu | Question:
The black robin is one of the world's rarest birds. It is a small, wild bird, and it lives only on the island of Little Mangere, off the coast of New Zealand. In 1967 there were about fifty black robins; in 1977 there were fewer than ten. These are the only black robins left in the world. The island has many other birds, of different kinds, large and small; these seem to multiply very happily. Energetic steps are being taken to preserve the black robin. Detailed studies are going on, and a public appeal for money has been made. The idea is to buy another island nearby as a special home, a "reserve", for threatened wild life, including black robins. The organizers say that Little Mangere should then be supplied with the robin's food--it eats only one kind of seed. Thousands of the required plants are at present being cultivated in New Zealand. The public appeal is aimed at the conscience of mankind, so that the wild black robin will not die out and disappear form the earth in our time at least. Is all this concern a waste of human effort? Is it any business of ours whether the black robin survives or dies out? Are we losing our sense of what is reasonable and what is unreasonable? In the earth's long, long past, hundreds of kinds of creatures have evolved, risen to a degree of success--and died out. In the long, long future, there will be many new and different forms of life. Those creatures that adapt themselves successfully to what the earth offers will survive for a long time. Those that fail to meet the challenges will disappear early. This is nature's proven method of operation. The rule of selection--"the survival of the fittest"--is the one by which human beings have themselves arrived on the scene. We, being one of the most adaptable creatures the earth has yet produced, may last longer than most. You may take it as another rule that when, at last, human beings show signs of dying out, no other creature will extend a paw to put off our departure. On the contrary, we will be hurried out. For nature, tough fair, is a hard-hearted mistress. She has no favorites. Life seems to have grown too tough for black robins. I leave you to judge whether we should try to do something about it. The writer's attitude towards the protection of the black robins is _ .

A. passive
B. active
C. unconcerned

mmlu | Question:
When scientists accidentally killed what turned out to be the world's oldest living creature, it was bad enough. Now, their mistake has been worsened after further research found it was even older - at 507 years. The ocean quahog, a type of deep-sea clam, was dredged alive from the bottom of the North Atlantic near Iceland in 2006 by researchers. They then put it in a fridge-freezer, as is normal practice, unaware of its age. It was only when it was taken to a laboratory that scientists from Bangor University studied it and concluded it was 400 years old. The discovery made it into the Guinness Book of World Records. However, by this time, it was too late for Ming the Mollusc , named after the Chinese dynasty when its life began. Unfortunately researchers who calculated Ming's age killed it instantly by opening its shell. The researchers opened the ancient clam up to judge its age by counting growth rings inside. But the rings were so close together that scientists ended up having to count the rings on the outside to be accurate, leading CBS journalists to point out that if scientists had just started there, Ming could have lived on. Now, after examining the quahog more closely, using more advanced methods, the researchers have found the animal was actually 100 years older than they first thought. Dr Paul Butler, from the University's School of Ocean Sciences, said: "We got it wrong the first time and maybe we were a bit hasty publishing our findings back then. But we are absolutely certain that we've got the right age now." The mollusc was born in 1499 - just seven years after Columbus discovered America and before Henry VIII had even married his first wife, Catherine of Aragon in 1509. A quahog's shell grows by a layer every year, in the summer when the water is warmer and food is plentiful. It means that when its shell is cut in half, scientists can count the lines in a similar way that trees can be dated by rings in their trunks. Jan Heinemeier, associate professor at the University of Denmark, who helped date Ming, told Science Nordic: "The fact that we got our hands on a 507-year-old animal is incredibly fascinating, but the really exciting thing is of course everything we can learn from studying the mollusk." Which of the following is NOT true?
Choices:
A. The researchers have got the right age of the ocean quahog.
B. The mollusc was born after Columbus discovered America.
C. The ocean quahog was named after the Chinese dynasty.
D. A quahog's shell grows by a layer every season. | D |

Some people would have you believe that being fat is the worst thing you can be. They think that if a person is fat they have no life, no love, no reason to want to look good in their clothes. The sad thing is that many people who are fat do feel the same loathing toward themselves and others who are overweight or obese. I know what I'm talking about because I have been there. I have been that fat girl who wore big T-shirts to cover my "sins". Forget style. Forget fashion sense. I absolutely had none. I didn't even bother getting haircuts for years, just wore my hair long and straight, pulled back in a ponytail, I have to wonder if the reason the fashion industry has ignored plus sized women and children for so long is because plus sized people, feeling they couldn't possibly look great, didn't bother shopping for new clothes, and therefore no profit was to be found by producing those sizes. For me, the change that improved my outer look actually started with my outlook on life. I started by being grateful for all I do have, like great health, a stable family, a steady income, freedom, a decent home, the ability to see the trees turn orange in the fall, to hear my grandson humming in the back seat, to remember the great times I've had in my life. I started to focus on all the positive aspects of the life I already had. I actually started to feel the beauty of the Universe all around me and to realize that I am part of that perfection. The self loathing stopped. I noticed all the people in my life who loved me in spite of my size. I got off the pity pot and smiled at myself. I acknowledged my shame and embarrassment and moved through that too. The author is probably _ .

WASHINGTON---Think you're savvy about food safety? That you wash your hands well, scrub away germs, cook your meat properly? Guess again. Scientists put cameras in the kitchens of 100 families in Logan, Utah. What was caught on tape in this middle-class, well-educated college town suggests why food poisoning hits so many Americans. People skipped soap when hand-washing. Used the same towel to wipe up raw meat juice as to dry their hands. Made a salad without washing the lettuce. Undercooked the meat loaf. One even tasted the marinade in which bacteria-ridden raw fish had soaked. Not to mention the mom who handled raw chicken and then fixed her infant a bottle without washing her hands. Or another mom who merely rinsed her baby's juice bottle after it fell into raw eggs---no soap against the salmonella that can lurk in eggs. "Shocking," was Utah State University nutritionist Janet Anderson's reaction. Specialists call this typical of the average U.S. household: Everybody commits at least some safety sins when they are hurried, distracted by fussy children or ringing phones, simply not thinking about germs. Even Anderson made changes in her kitchen after watching the tapes. The Food and Drug Administration funded Anderson's $50,000 study to detect how cooks slip up. The goal is to improve consumers' knowledge of how to protect themselves from the food poisoning that strikes 76 million Americans each year. "One of the great barriers in getting people to change is they think they're doing such a good job already," said FDA consumer research chief Alan Levy. Surveys show most Americans blame restaurants for food-borne illnesses. Asked if they follow basic bacteria-fighting tips---listed on the Internet at www.fightbac.org---most insist they're careful in their kitchens. Levy says most food poisonings probably occur at home. The videotapes suggest why. People have no idea that they're messing up, Anderson said. "You just go in the kitchen, and it's something you don't think about." She described preliminary study results at a food meeting last week. Having promised the families anonymity, she didn't show the tapes. For $50 and free groceries, families agreed to be filmed. Their kitchens looked clean and presumably(perhaps) they were on their best behavior, but they didn't know it was a safety study. Hoping to see real-life hygiene, scientists called the experiment "market research" on how people cooked a special recipe. Scientists bought ingredients for a salad plus either Mexican meat loaf, marinaded halibut or herb-breaded chicken breasts with mustard sauce---recipes designed to catch safety slip-ups. Cameras started rolling as the cooks put away the groceries. There was mistake No. 1: Only a quarter stored raw meat and seafood on the refrigerator's bottom shelf so other foods don't get contaminated by dripping juices. Mistake No. 2: Before starting to cook, only 45 percent washed their hands. Of those, 16 percent didn't use soap. You're supposed to wash hands often while cooking, especially after handling raw meat. But on average, each cook skipped seven times that Anderson said they should have washed. Only a third consistently used soap---many just rinsed and wiped their hands on a dish towel. That dish towel became Anderson's nightmare. Using paper towels to clean up raw meat juice is safest. But dozens wiped the countertop with that cloth dish towel---further spreading germs the next time they dried their hands. Thirty percent didn't wash the lettuce; others placed salad ingredients on meat-contaminated counters. Scientists checked the finished meal with thermometers, and Anderson found "alarming" results: 35 percent who made the meat loaf undercooked it, 42 percent undercooked the chicken and 17 percent undercooked the fish. Must you use a thermometer? Anderson says just because the meat isn't pink doesn't always mean it got hot enough to kill bacteria. Anderson's study found gaps in food-safety campaigns. FDA's "Fight Bac" antibacterial program doesn't stress washing vegetables. Levy calls those dirty dish towels troubling; expect more advice stressing paper towels. Anderson's main message: "If people would simply wash their hands and clean food surfaces after handling raw meat, so many of the errors would be taken care of." What prevents many Americans practicing better food safety in their kitchen?

TOKYO (Reuters) - "Who played the father in the movie 'Kramer versus Kramer'?" That's one of the 50 questions Japanese men could face in a "daddy exam", meant to raise awareness about fatherhood in a country where men tend to work long hours and leave their wives in charge of childcare and household work. Even men who remember Dustin Hoffman struggling as a father in the movie may have a hard time answering questions ranging from baby food to politics. Tetsuya Ando, director of Fathering Japan, a Tokyo non-profit organization that came up with the test and will offer it to eager dads from next March, said the exam was an attracting way to get fathers into parenting. "There just isn't enough information about parenting for fathers. Through the exam, we want men to realize that they don't know anything about bringing up kids," he said. For the price of 3,900 yen ($34), fathers can find out whether they qualify as a "Super Dad," or are in need of more effort as a "Challenge Dad." "We have received inquiries from fathers, single men, to-be-dads, grandfathers ... even an aunt who was concerned that her nephew is too busy with work to notice the fun of parenting," Ando said. The image of fathers is gradually changing in Japan as younger men _ their own dads' hands-off way in favor of closer involvement, and a wave of new parenting magazines for male readers has been hitting newsstands. But it is still hard for Japanese fathers to cut down on their work hours and spend more time with their families. Only 0.5 percent of employed men in Japan took parental leave in 2011, compared with 14 percent in the United States and 12 percent in Britain in 2000. The magazines for male readers are popular most probably because many men _ .

During my free time one day, I wandered down a lonely path into the woods and sat against a tree. Then I saw one of the camp _ approaching me. "Oh great," I thought, since counselors were always trying to cheer you up or make you laugh. "Hey," he said, "mind if I have a seat?" I shrugged . I wasn't going to encourage him, but I couldn't exactly stop him, either. He sat down alongside me and extended a hand. "I'm Gary," he said, "and you're Erica, right?" I nodded. "You don't exactly look like you're having a good time," he began. I crossed my arms and gritted my teeth. "Look," I said, "I didn't want to come to camp, I don't like it, I'm not having fun, and it basically stinks." I glared at Gary. "So there's nothing here at all for you, huh?" he asked. "Nothing," I answered. "Let me show you something," said Gary. He got up, and I followed him along the path until I heard a sound like a roaring freight train. "What's that?" I asked. "Wait and see," he replied, with a small smile. When we rounded the corner, I couldn't believe what I saw. There was the biggest waterfall I could ever imagine, right in front of me. "Cool!" I said, and I could feel my eyes getting bigger and a smile tugging at my mouth. "Still think there's nothing here for you?" asked Gary. "Because there's a whole lot more of this kind of 'nothing' around here." I had to admit, the waterfall was impressive. "Look," said Gary, "camp is what you make it. You can be sullen and closed-minded and have a rotten four weeks, or you can take a look around you and see some of the incredible sights and appreciate the opportunity. It would be useless for me to try to make you have fun. You can only do that for yourself. But if you loosen up a little, you might actually have a good time." With that, he turned and walked away, leaving me on the path. That night, by the campfire, I found myself singing along with everyone else. By the time the four weeks were up, I didn't want to leave. I'd seen some amazing things and made some great friends. Beauty is where you find it. Life is what you make it. I think it's going to be a good year this year.

Dear Tommy, I'm writing to you on your third birthday. I want to tell you something about your grandma's time. I was born sixty-eight years ago in a small village. Transportation used to be a big problem. When we travelled from village to village, we used to walk or ride horses. Shopping was not an easy job, either. There were no supermarkets in the neighborhood. We used to grow most of our own food: rice and vegetables. We kept things cool in a special underground room. The biggest difference is that you have electricity. We didn't have electricity until very late in our small village. We didn't have any televisions of course. We used to perform our local music and enjoy it very much. Life used to be very hard, but I was not upset. I would like you to know about the old days and be happy about what you have.

A deadly strain of avian flu may have passed between people for the first time, experts believe.The avian influenza A (H7N9) virus is thought to have been transmitted between father and daughter in eastern China, according to research published online by the British Medical Journal (BMJ). The findings provide the strongest evidence yet of H7N9 transmission between humans since its discover in February, but its ability to transmit itself _ "limited and non-sustainable" by the Chinese researchers behind the study.At the end of June 133 cases had been reported, including 43 deaths. Most infections have been among people visiting markets, selling live birds or among those who had contact with live poultry in the seven to 10 days before becoming ill. The latest study examined the case of a 60-year-old father who regularly visited a live poultry market and became ill five to six days after his last visit in March. He was admitted to hospital with fever, cough and shortness of breath. Despite intensive care treatment he died of multiple organ failure on 4 May. His 32-year-old daughter, who was previously healthy, looked after him at his bedside before he was admitted to intensive care. She had no known exposure to live poultry before falling ill with a very high temperature, cough and fever. The daughter developed symptoms six days after her last contact with her father and was admitted to hospital where she died of multiple organ failure on 24 April. Follow-up investigations uncovered almost genetically identical virus strains from each patient, suggesting transmission from father to daughter. Another 43 people were also tested who had had close contact with the father, daughter or both. Dr Peter Horby, senior clinical research fellow at the Oxford University Clinical Research Unit in Hanoi, Vietnam, said of the study: "The most likely source of infection for the daughter was her father, during the period that she cared for him while he was ill. "He said "limited person to person transmission had been reported for other strains like H5N1 , H7N7, and the pig origin flu virus H3N2. Those strains had been around for more than a decade but have not progressed any further down the path towards a world-wide virus." "Limited human-to-human transmission of H7N9 virus is therefore not surprising, but strengthening to monitor it was still needed," Dr Horby added. Which of the following is Wrong about H7N9 transmission?
Choices:
A. It was limited and non-sustainable
B. It was person to person transmission
C. It wasn't progressed any further down the path towards a world-wide virus.
D. It happened between father and daughter . | D |

Patients and doctors alike have long believed in the healing power of humor.It is claimed that humor not only affects patients' moods, but can actually help them recover faster. Several studies seem to support this.Patients in better spirits are known to have higher immune cell counts.Some have even claimed to have healed themselves of serious illnesses by reading comics and watching comedies. Despite all this, many researchers are not convinced.They point out the fact that many sufferings have been known to disappear naturally, with or without a daily dose of laughter.They also say that while optimism in general does seem to be related to better health, it is hard to tell which comes first. Humor in times of stress, however, clearly makes us feel better.On one level, it takes our minds off our troubles and relaxes us.On another, it releases powerful endorphins, a chemical produced by your body that reduces pain. There are cases where the appreciation of a good joke is indeed directly related to a person's health.It can show, for example, whether a person has suffered damage to one particular area of the brain: the right frontal lobe . Scientists confirmed this by having people read jokes and asking them to choose the funniest endings from a list.Subjects with normal brains usually chose endings that were based on a relatively complex synthesis of ideas.Subjects with specifically located brain damage, however, responded only to slapstick endings, which did not depend on a particular context.When pressed, the brain-damaged subjects saw the logic in the correct endings.They simply did not find them funny. Of course, humor is largely an individual matter.Next time your friend does not get one of your jokes, there is no need to accuse him of being a lamebrain.However, you might suggest that he lighten up--for the health of it. Which of the following statements is NOT true?
Choices:
A. Many researchers are not convinced of the healing power of humor.
B. Patients in bad moods are known to have higher immune cell counts.

Cycling isn't always easy. Busy streets and few bike lanes and parking areas can make it a battle. But not even these difficulties can stop Europeans' love for cycling. According to Reuters, more bicycles have been sold than cars in 26 of the European Union's 28 states this year. In some European countries, people really love bicycles. "People ride to work and take their bikes to the grocery store", Bill Strickland, editor of Bicycling magazine, told the reporter from Reuters. So what has led to cycling's growing popularity in Europe? Cycling is "a safe, clean, healthy, inexpensive way to get around town," the Daily Star concluded. "It not only reduces traffic problems and pollution, but also contributes to public health." Bike-friendly rules have also been made. Dozens of cities have joined a European Union initiative to make bicycles a form of city transport, like cars. Quite a few cities such as Stockholm, London, Florence and Munich now offer special bike lanes. Copenhagen takes it a step further by keeping bicycles and cars separated as much as possible. On these _ , traffic lights are designed to the rhythms of bicycles, not cars. For people living far from city centers, getting to work by bicycle alone may take too much time. That's why many European countries now allow cyclists to bring their bicycles onto subway trains. Europeans are also creative in solving parking problems. Amsterdam has come up with a high-tech solution: you lock your bike to a rack , which then goes underground. When you want your bike back, it is brought back to the surface. Which of the following can be the best title for the passage?

Last year, Jin Yucheng'sFanHuawas taken to Salon du livre, France's largest book fair, along with other contemporary Chinese literary works such as Bi Feiyu'sSubeiYouth"DonQuixote". The two books attracted the attention of Editions Philippe Picquier, a French publisher that specializes in translating books from China, Japan, South Korea, India, Vietnam and other countries in Asia. This publisher reportedly purchased the copyright ofSubeiYouth"DonQuixote", a non-fiction work about the writer's childhood in East China's Jiangsu province, for 130,000 euros ($143,000). Editions Philippe Picquier was also interested inFanHua, but didn't follow up owing to translation issues. The book is Jin's debut novel, which is set in Shanghai and tells stories of two decades: the 1960s and the 1990s. There are no major plots, but excerpts from the lives of its different characters, threaded by dialogues. There are detailed depictions of streets, entertainment activities and relationships in the representative times in Shanghai, covering the"Cultural Revolution"(1966-1976) and the"Reform&Opening Up"phases. As Hong Kong-based film director Karwai Wong put it, the novel is full of a"rich and strong"flavor of local people's lives. In May 2011, when Jin, then an editor at a literary magazine in Shanghai, started to post interesting stories he heard about Shanghai on the local website longdang.org, little did he realize that it would become more than just fun. His stories soon attracted more readers whose comments urged him to post more. In five months, Jin, then 59, wrote more than 330,000 characters online. The novel was first titledShanghaiAbaoafter its major character Abao. The following year, Jin started serializing his novel inHarvest, one of China's leading literary magazines. Finally, Jin's efforts resulted in a book in 2013, and with it came lots of awards, including the 9th prestigious Mao Dun Literature Prize. Some critics compare it with fellow Shanghai-based author Eileen Chang's novels andDreamoftheRedChamber, calling Jin's book one of the best novels based on Shanghai. Wong also announced that he would adapt Jin's book for cinema by 2020. By August, before the Mao Dun Literature Prize winners were announced,FanHuahad sold nearly 300,000 copies. Key features of the novel include the use of the local Shanghai dialect for the narrative and focus on the characters' external responses to events rather than their psychological profiles. The copyright manager forFanHuaat Shanghai Literature and Art Publishing House says,"According to my knowledge, Editions Philippe Picquier gave up because the translation work is expensive and they worry that the sales in the French market may not be able to cover the cost."For instance,ChanghenGe(TheSongofEverlastingRegret) by Wang Anyi was also introduced by Editions Philippe Picquier to French readers. The translation work took one and a half years, and the publisher spent three years completing the French edition ofit."But we have soldFanHua'scopyright of the traditional Chinese edition to Hong Kong, Taiwan and Macau. Also Humanist Publishing House from South Korea has purchased the copyright for the Korean edition. Cultural difference is another barrier apart from language. In Asia, we have more in common when it comes to culture." What can we learn aboutFanHuaandSubeiYouth"DonQuixote"?

A. They were both translated into French.
B. They became famous on a French book fair.
C. They were both well-known to film directors.
D. They were both noticed by Editions Philippe Picquier. | D |

The rainbow lorikeet is a kind of parrot in the northeast of Australia. It is the most colorful and noisy bird in the world. The bird has green, orange, blue, red, yellow, purple and grey colors on its body. Rainbow lorikeets are small birds. They are usually 11 to 12 inches long and weigh 120g to 140g. It is said that they can live for over 20 years in the wild. They usually live in groups. At night, they sleep in the trees in a big group. But during the daytime, they move in much smaller groups (about 20 birds). Late in the evening, you can sometimes see a larger group flying back home. These birds spend a lot of time looking for food. Most of their food comes from trees, like flowers, nuts and fruit. But sometimes they eat insects. They can get water from the leaves that they eat or drink water directly. Rainbow lorikeets usually start to have families when they are around two years old. When they have baby birds, both the parents help to feed them. Which of the following is TRUE according to this passage?

mmlu | Question:
A relationship is defined as a state of connectedness between people. Although in today's society with its crazy rhythm of everyday life, when people tend to live in thickly populated cities, spending most of their time in the office and hardly knowing their neighbor's name, we still find ourselves in some kinds of relationships-with friends, family, or colleagues. Family relationships are the first relationships people enter. Parents and relatives influence our emotional development by creating a model that we are sometimes bound to follow all our lives, often subconsciously . In day-care, at school, then in the office we spend a lot of time among fellow students and co-workers. We learn to keep business relationships, to work in a team environment, then form smaller groups of like-minded people and finally select some of them as our friends. What is a true friendship? How does it start? Are we destined to become friends with certain people or can we actually plan whom to be friends with? "Everybody's friend is nobody's." said Arthur Schopenhauer. Unlike a companionship based on belonging to the same team or group, friendship is a very personal and selective type of relationship. It calls for trust, sincerity, and emotional bonds. Sociologists believe that most people are looking for similarities in views, social status, and interests when choosing friends. No wonder that our friends are often people of the same age, sex, and education. Another important factor is joint activity and solidarity. This is the reason why many of us befriend our colleagues and other people who work in the same field. Most people would agree that a friend is someone who always listens and understands. Understanding in this context implies a lot of meanings-compassion, sympathy, and emotional closeness. It's a process in which your friend reads your emotional state, shares your feelings, identifies himself or herself with you. Which of the following statements is NOT true?
Choices:
A. A companionship is based on belonging to the same team or group.
B. Friendship needs trust, sincerity, and emotional bonds.
C. Relationships are friendships between people.
D. Understanding is a process in which the friend reads our emotional state, shares our feelings, identifies himself / herself with us. | C |

mmlu | Question:
We might think we know which colours do what.The idea that red wakes us up or blue calms us down is deeply rooted in Western culture.But do they really change our behaviour in the ways that we assume? When it comes to scientific research, the results are mixed and at times contested.Some studies have found that people do better on cognitive tasks when faced with red rather than blue or green; others show the opposite.The idea is that if you repeatedly have a particular experience surrounded by a certain colour, then you eventually begin to associate that colour with the way you were feeling or behaving.A school career spent reading your teacher's red writing circling your mistakes forever makes you link red with danger.Blue meanwhile is more likely to be associated with calmer situations like marvelling at a big blue expanse of sky. Of course there will always be exceptions --- the comment from the teacher saying "well done" is also written in red.It is true that people do make different associations with different colours, but whether this translates into behaving in a certain way or succeeding at a particular task is a different question. In 2009 researchers tried to clarify the situation.They sat their participants at computer screens colored blue, red or "neutral" and tested them on various tasks.With a red screen people did better on tasks requiring attention to detail, but when the screen was blue they did better on creative tasks.In practice this might be tricky.In a classroom you might want to think creatively some of the time and pay attention to detail at others. However, when another team tried to repeat the study with a larger group of people in 2014, the effect of color disappeared.The initial study consisted of just 69 people.In this new, bigger study, of 263 volunteers, background color made no difference. So colors might well have an effect, but so far those effects have been difficult to demonstrate consistently and sometimes don't seem to exist at all. It can be concluded from the results of the studies in 2009 and 2014 that _ .

It might not come as a surprise that China fell behind Western countries in a recent UN report on global happiness. China was only ranked 112th happiest country out of 156 in the UN's World Happiness Report in April. The happiest country, it seems, is Denmark, closely followed by three more northern European countries- Finland, Norway, and the Netherlands. But apart from income and lifestyle differences, there are also cultural reasons for this divide. They show that Chinese people and Westerners have different perceptions of happiness. According to a survey conducted by CCTV, income levels most affected Chinese people's sense of well- being (55.5 percent), followed by health (48.9 percent) and quality of marriage or love life (32 percent). It seems that all these criteria are lagging in China, and that the obvious explanation for greater happiness in the West is higher incomes. But not so, says Professor John Helliwell, an American economist at the University of British Columbia and coauthor of the UN report. According to Helliwell, low-income individuals may experience an initial jump in happiness when their money increases, but this feeling decreases as they adapt to their new circumstances. He stresses the example of the US, where, despite GDP figures rising consistently for the past 50 years, happiness has been steadily declining. This is because people desire more than money and material wealth. "To be happy, we need to feel connection, trust and meaningful relationships," explains Helliwell. Dr Deborah Swallow, a UK expert on cultural diversity however, believes there are some differences in the perceptions of happiness in the West and China. "For North Americans and Europeans, happiness tends to be defined in terms of personal achievement, and is best predicted by self-esteem" she says. "For East Asians, happiness tends to be defined in terms of interpersonal connectedness, and is best predicted by how well involved the self is in a social network." Living standards are not necessarily the last word on happiness, as suggested by China's Urban Happiness Ranking 2012, released by the Hong Kong-based China Institute of City Competitiveness in July. According to the survey's results, Qingdao in Shandong province is China's happiest city with a score of 95.08. Surprisingly, China's first-tier cities scored ly low, with Shenzhen ranking 94th, Beijing 96th and Shanghai in 99th position. According to the passage, which of the following about happiness is Correct?
Choices:
A. Happiness has nothing to do with money.
B. A man with healthy body must have the most happiness.
C. A man who has a strong social relationship is sure to be happy.
D. People's sense of happiness is determined by many factors. | D |
mmlu | Question:
When I was about 12, I had an enemy , a girl who liked to point out my shortcomings . Week by week her list grew: I was very thin; I wasn't a good student; I talked too much; I was too proud , and so on. I tried to hear all these as long as I could. At last, I became very angry. I ran to my father with tears in my eyes. He listened to me quietly. Then he asked, "Are the thing she said true or not? Janet, didn't you ever think about what you are really like? Well, you now have that girl's opinion. Go and make a list of everything she said and mark the points that are true. Pay no attention to the other things she said." I did as he told me. To my great surprise, I discovered that about half the things were true. Some of them I couldn't change (like being very thin), but a good number I could --- and suddenly I wanted to change. For the first time I got a very clear picture of myself. I brought the list back to Daddy. He wouldn't like to take it. "That is just for you," he said, "You know better than anyone else the truth about yourself. But you have to learn to listen, not just close your ears in anger and feeling hurt. When something said about you is true, you will find it will be of help to you. Our world is full of people who think they know your duty. Don't shut your ears. Listen to them all, but hear the truth and do the right thing." Daddy's advice has returned to me at many important periods. In my life, I have never had a better piece of advice. Why did the writer's father listen to her quietly? Because _ .

A. he believed that most of what his daughter's "enemy" said was true.

mmlu | Question:
Deception is something that people do all the time ,and it plays an important role in military strategy. Now some researchers are trying to figure out how to get robots to do it, by looking at the behavior of squirrels and birds. At Georgia Tech, a team led by Ronald Arkin , a professor at the School of interactive Computing, studied the literature on squirrels hiding their acorns .Squirrels will hide their food m a certain place, but when they see other squirrels trying to steal from them, they attempt to fool the thieves by running to a fake location. Ronald Arkin and his Ph. D. student Jaeeun Shim used that as a model for robot behavior. They programmed the robot into tricking a "predator " machine by doing what ei squirrel does: showing the enemy a false location for an important resource. The team also looked at how other animals in this case,a species of bird called Arabian babbler~ drive off predators. A babbler will make an alarm call when they see a predator and other babblers will join the bird and make more calls. They then surround the predator, all the while flapping wings and making noises. The babblers don't ever actually fight the animal they want to drive off; they just make enough noises and flaps around enough so that it seems that attacking a babbler isn't worth it They found that the deception works when the group reaches a certain size--essentially, when enough birds arrive to convince the enemy that it's best to back off . Davis modeled that behavior in software using a military scene and found that it worked even if the group didn't have the firepower to confront the enemy directly. The military is interested in this because a robot that can fool an opponent is a valuable tool. It could lead an enemy down a fake trail or make itself look more dangerous than it actually is. Which of the following is NOT the way Arabian babblers drive off predators?
Choices:
A. One bird makes an alarm call and other birds will join it
B. They fight the enemy bravely face to face.
C. They make noises and flaps around the predator.
D. They force the predator aware that it isn't worthwhile to attack. | B |

It had been some time since Jack had seen the old man. College, career, and life itself got in the way. In fact, Jack moved clear across the country in pursuit of his dreams. There, in the rush of his busy life, Jack had little time to think about the past and often no time to spend with his wife and son. He was working on his future, and nothing could stop him. One day, over the phone, his mother told him that Mr. Belser died the night before and the funeral would be on Wednesday. "Oh, it's been so long since I thought of him. I'm sorry, but I honestly thought he died years ago," Jack said. "Well, he didn't forget you. Every time I saw him he'd ask how you were doing. He'd recall about the many days you spent over 'his side of the fence' as he put it," Mom told him. "I love that old house he lived in. He's the one who taught me carpentry. I wouldn't be in this business if it weren't for him. He spent a lot of time teaching me things he thought were important... Mom, I'll be there for the funeral," Jack said. Busy as he was, he kept his word. Mr. Belser's funeral was small and uneventful. He had no children of his own, and most of his s had passed away. The night before he had to return home, Jack and his Mom stopped by to see the old house next door one more time, which was exactly as he remembered. Suddenly Jack stopped. "The box is gone," he said. "What box?" Mom asked. "There was a small gold box that he kept locked on top of his desk. I must have asked him a thousand times what was inside. All he'd ever tell me was 'the thing I value most'", Jack said. "Now, I'll never know what was so valuable to him," Jack said sadly. Returning to his office the next day, he found a package from Mr. Harold Belser on his desk. Jack tore open the package. There inside was the gold box and an envelope. "Upon my death, please forward this box and its contents to Jack Bennett. It's the thing I valued most in my life." A small key was taped to the letter. His heart racing, and tears filling his eyes, Jack carefully unlocked the box. There inside he found a beautiful gold pocket watch. Running his fingers slowly over the fine cover, he opened it. Inside he found these words carved: "Jack, thanks for your time! Harold Belser." "Oh, My God! This is the thing he valued most..." Jack held the watch for a few minutes, then called his assistant and cleared his appointments for the next two days. "Why?" his assistant asked. "I need some time to spend with my son," he said. Why did Belser send Jack his gold watch?
Choices:
A. Because he thought he had to keep his word.
B. Because he had no children or s.
C. Because he was grateful for Jack's time with him.
D. Because Jack had always wanted it during his childhood. | C |

I was twenty years old, and my parents were looking forward to the day when I would be earning my own living. Unfortunately, I had absolutely no idea what I wanted my future occupation to be. The only thing I did know was that I did not want to spend the next 45 years teaching, being a nurse or sitting in an office. But that was before the postman delivered a catalogue of courses that were being offered at the local college. As I looked through it, I was attracted by a page that talked about the difficulties faced by deaf people in their everyday lives and how students could help by learning sign language. It went on to say that graduates of the course usually find work in different organizations, such as law companies, the Stock Exchange, insurance companies and banks. Then I saw something that really caught my eye: "Singer" are also needed for sporting events, concerts, theatrical performances and, believe it or not, circuses! By the time I got to the bottom of the page, I knew I had found the perfect occupation. I enrolled on the course, which to my parents' great delight was free of charge. The course was brilliant. My favourite part was the final lesson, when our teacher asked us to sign our favourite song. It was really difficult because not only did we have to sign the words, but we also had to find a way of showing whether the song was happy or sad and whether the beat was slow or fast. It was the hardest thing I have ever done--but also the most rewarding. Which of the following best describes the writer?

Once, looking for stories on the back roads of Ohio, _ . A beekeeper we'd been told about was away from home when we called on him. An amusement park where we thought we might find a story had shut down for the season. We began to get a little discouraged. When passing a farmhouse, we found a banner in the front yard. The banner said in huge letters: WELCOME HOME, ROGER! We drove on for a mile or two. Somebody said, " wonder who Roger is ?" We turned around, went back and knocked on the door. Roger was a soldier on his way home from the Vietnam War. His family knew he was coming, but weren't sure what day he was going to arrive. We asked if they 'd mind if we brought the camera into the house. Roger's mother said it would be all right if we could give her a few minutes to fix her hair. We weren't there more than an hour, talking to those people who were all excited about Roger coming home. That afternooon I wrote a simple story letting Roger represent all the soldiers coming home from war. We sent the film with the story to New York, and the anchorman put it on the Evening News. Rarely has any of our stories caused such a reaction from viewers. There were dozens of calls from people moved by it, and hundreds of letters came in, some of them suggesting that the story be repeated. That hour with Roger's family made it a good trip to Ohio, after all. I had done a lot of careful planning for the week's work, but in vain. Then along came a banner in a farmhouse yard. Back at the office, people asked , " How do you find these stories ?" "Well," I said," you do have to work at it." All you really have to do is look out of the window.

A. Roger's family were excited at the author's coming.

mmlu | Question:
The loss of a job can have a very serious impact on the individual. The immediate effect, of course, is a sharp drop in income. Unemployment benefits typically offer less than half the individual's previous earnings, and many people are not even entitled to these benefits-for example, the self-employed, recent graduates who have not held a steady job in the previous year, and people who have been unemployed for a long period. The economic pressure on the jobless is very severe, particularly for those who have young children or long-term commitments for expenses for houses and education. But the effects of unemployment are not merely financial; they are also social and psychological. As one out-of-work teacher puts it: "It's difficult when you strip away all the things that supposedly hold you together in terms of an identity. Your work, your money, whatever is power to you, whatever is responsibility, whatever means freedom and choice." I had to ask myself, "Who am I now? What will I do now?" All too often, long-term unemployment may thrust the individual into boredom, despair, ill-temper, and perhaps, conflict with other family members. Even those who keep their jobs are affected by rates of unemployment, for they begin to fear for own future. Lacking the confidence that workers have in times of full employment, they negotiate less aggressively for improvements in pay or working conditions, for they and the employers know that if they do not like the job as it is, others will gladly take it. Unemployment is always accompanied, in fact, by underemployment-the situation in which people are working either for extremely low wages or at jobs below their level of skill. By "underemployment"(Line 12, Para. 2), the writer means the situation in which _ .

Country music usually talks of everyday life and feelings. It's the spirit of America ,easy to understand ,slow and simple. Country music developed in the Southern United States. It was the folk music of American countryside. Many of songs tell about the lives of famers . They talk about love, crops or death. The life of the countryside can be hard, so the words in country music are often sad. At first, people played the music only at family parties. But it became more popular later. In the 1920s,people played country songs on the radio, and they made them into records. When people in the countryside moved to towns and cities to look for work, they took their music with them.

Most musicians agree that the best violins were first made in prefix = st1 /Italy. They were made inCremona,Italy, about 200 years ago. These violins sound better than any others. They even sound better than violins made today. Violin makers and scientists try to make instruments like the old Italian violins. But they aren't the same. Musicians still prefer the old ones. No one really knows why these old Italian violins are so special, but many people think they have an answer. Some people think it is the age of the violins. They say that today's violins will also sound wonderful someday. But there is a problem here. Not all old violins sound wonderful. Only those from Cremonaare special. So age cannot be the answer. There must be something different aboutCremonaor those Italian violin makers. Other people think the secret to those violins is the wood. The wood of the violin is very important. It must be from certain kinds of trees. It must not be too young or too old. Perhaps the violin makers of Cremons knew something special about wood for violins. But the kind of wood may not be so important. It may be more important to cut the wood in a special way. Wood for a violin must be cut very carefully. It has to be the right size and shape. The smallest difference will change the sound of the violin. Musicians sometimes think that this was the secret of the Italians. Maybe they understood more than we do about how to cut the wood. Size and shape may not be the answer either. Scientists measured these old violins very carefully. They can make new ones that are exactly the same size and shape. But the new violins still do not sound as good as the old one. Some scientists think the secret may be the varnish, which covers the wood of the violin and makes it look shiny. It also helps the sound of the instrument. No one knows what the Italian violin makers used in their varnish. So no one can make the same varnish today. There may never be other violins like the violins of Cremona. Their secret may be lost forever. Young musicians today hope this is not true. They need fine violins. But there aren't very many of the old violins left. Also, the old violins are very expensive. Recently, a famous old Italian violin was sold for about US $ 300,000!

If you're ever apart from your children, a new study says just talking on the phone will help just as much as a hug . If you're a parent who spends long hours on the job, you probably feel sorry for spending so much time away from your kids. But the results of a new study show that a mother's voice alone can be just as comforting to an anxious child as physical contact . In an experiment, researchers from the University of Wisconsin-Madison asked a group of girls between the age of 7 and 12 to solve math problems in front of judges --- a stressful situation for anyone. Before the girls were set to solve math problems, the researchers measured their levels of two hormones : cortisol, which goes up during stressful periods, and oxytocin, the "love" hormone. After they were finished, some of the girls got to meet up with their mothers right away. The mums came in and hugged the girls. Another group of the girls didn't see their mothers, but received phone calls from them, in which their mothers told them how well they'd done. The final group had no contact with their mothers, but watched an animal movie, March of the Penguins instead. Finally, the girls' hormone levels were measured again. Although the movie was interesting, it did nothing to ease the children's anxiety ---- but, surprisingly, both the physical contact and phone calls from their mothers had the same effect on easing the girls' stress levels. So, no matter how old you are, if you're feeling stressed about something in your life, a phone call to Mom might be just the key to help you feel better. According to the passage, we can infer that _ .

Annabelle Smith and her two best friends, Samantha and Kristy, loved going to Sand City School. Mrs. Lemming, their teacher, would read them a story. That Monday afternoon, Mrs. Lemming read them a story called Super Sophie Saves the Day. After school, Annabelle, Samantha and Kristy walked home together. "I decide that from now on I'm going to be a superhero like Sophie," Annabelle told her friends. "You mean heroine," Kristy said. "You're a girl, Annabelle." The next day Kristy and Samantha picked Annabelle up on their way to school. Annabelle had a red towel taped to her blue shirt. "I am Super Annabelle," Annabelle said. "I'll save someone on the way to school." Charlotte, another second-grader, walked past the girls. Her sweater was tied around her waist. She ran a little faster, and her sweater was nearly on the ground. Annabelle wondered what she would do. Giving her a dirty look, Charlotte ran away.

Many Chinese people who have been to the United States think that Americans pay a little part of their money for food each day. Yet, in the latest 13 years, food prices have gone up 30% for most American families. Everyone agrees that _ . But who is really responsible ? Many people say the farmers who produce the vegetables, fruit, meat, and eggs are responsible. But farmers say that the rise in food prices is very small compared to (...) the rise in their cost of living. Farmers think middlemen have got much more money than they do. Middlemen are those people who stand between the farmers and the people who buy and eat the food. For example, truck drivers, owners of food stores and so on. Are middlemen really responsible for higher food prices? Economists don't think so. They have found that the money that meat packers and food stores get is less than 1% in all. They say that food costs more now because modern housewives have jobs outside the home. They have less time for cooking after a day's work. They like to buy food which has already been prepared before it reaches the market. They want to buy many kinds of food that can be put on their dining tables easily and quickly. But of course they must be prepared to pay for the services of those who make their work easier. It seems that the answer to the question of rising prices is not an easy one. Quite a number of people share the responsibility for the sharp rise in food costs. What's the writer's opinion ?
Choices:
A. He agrees with the economists.
B. He doesn't think farmers are responsible.
C. He thinks the middlemen might get a lot of profit.
D. He thinks all those people should be responsible. | D |
mmlu | Question:
Focus on class SOME US parents are sad that their high school children score badly in math , science and reading compared to kids in other countries. There has been an endless series of mostly fruitless education reforms to address this gap ( ). Now comes an approach based on the insights of a group of US exchange students. They spent a year in some of the most successful high schools in the world -in Finland, Poland and South Korea. Author and journalist Amanda Ripley followed three exchange students for her new book, The Smartest Kids in the World - and How They Got That Way. She argues that to improve academics, US schools should de-emphasize sports. Instead, students should bring their passion and intensity to academics , she concludes. "High school in Finland, Korea and Poland had a purpose, just like high school football practice in America," she writes. "There was a big , important contest at the end, and the score counted." Sports are a distraction ,Ripley argues, and most countries require them to take place outside of school. Trading in US school sports culture would be a huge change for people in the US , who respect teamwork and sportsmanship as training for life. But playing down sports could pay off, as it has elsewhere, if we redirect money , focus and glory to learning. Ripley is critical of memorization in South Korean education, but she praises the system's high goals and the free-dom its students have to fail and recover through hard work. Too often , we don't ask teachers to give our kids harder assignments -and we're quick to complain about a failing grade. What's working elsewhere is to set ambitious goals for kids ,and then allow them to discover that they have it within themselves to reclaim success from failure. Each of the countries in Smartest Kids came to education reform after an economic crisis . Finland was losing jobs after graduating just 10 percent of its teens from high school in the 1950s. Today , the graduation rate is 95 percent . Poland's wakeup came in 1999, as students consistently tested below average in reading. We've tried so many "reforms" in education. Maybe what we need is a truly radical shift away from sports in favor of schooling. What is the author's attitude toward education reform in US high schools ?
Choices:
A. Indifferent.
B. Puzzled
C. Satisfied
D. Supportive. | D |

Canadian short story writer Alice Munro won the Nobel Prize for Literature. Eighty-two-year-old Munro is only the 13th woman to win the 112-year-old prize. Munro didn't publish her first collection of short stories until she was 37 years old, but her stories have always been well-received. Lots of her stories share similar themes and characters, but each story has its own twists and turns. Even though she's won Canada's most famous literary award, the Giller Prize, twice, winning the Nobel Prize for Literature is the cherry on top of Munro's career. "It brings this incredible recognition, both of her and her career, and of the dedication to the short story," said one person. Along with the well-respected title comes 1.3 million dollars.Munro said everything was "so surprising and wonderful" and that she was "dazed by all the attention and affection that has been coming my way." Munro knew she was in the running-she was named the second-most likely person to win this year's prize, after Haruki Murakami of Japan-but she never thought that she would win. Munro's win also represents the long way Canadian writers have come."When I began writing there was a very small community of Canadian writers and little attention was paid by the world.Now Canadian writers are read, admired and respected around the globe," Munro said on Thursday. She is technically not the first Canadian to win the Nobel Prize for Literature, but many like to think that she is.In 1976 Saul Bellow, who was born in Quebec but moved to Chicago when he was still a child, won the prize.Even though he was born in Canada, he is mostly considered to be an American writer. "This is a win for us all.Canadians, by our very nature, are not very nationalistic," said Geoffrey Taylor."But things like this suddenly make you want to find a flag." She wasn't sure if she would keep writing if she won the prize, saying that it would be "nice to go out with a bang.But this may change my mind." For Munro, the Nobel Prize is an award for _ .
Choices:
A. her love for Canadian culture
B. her devotion to the short story
C. her special form of writing
D. her career of editing short stories | B |

Authorities will continue to take a hard line on Internet-based rumors and punish those creating fake information, a senior official said on Thursday. Authorities have removed more than 210,000 online posts and shut down 42 websites since mid-March in their latest crackdown on online rumors, said Liu Zhengrong, a senior official with the State Internet Information Office. Fake information or rumors spread through the Internet, especially on micro blogs, have harmed social order and residents' daily lives, he said at a news briefing in Beijing. Before the crackdown, six people who allegedly fabricated rumors about "military vehicles entering Beijing" had been detained and 16 websites closed for fake online information, according to police authorities. "What we've done and will do is to make sure residents can know what they want to know, say what they think and supervise our management in a reliable and useful network environment," Liu said. Liu disagreed that the Internet can police itself against rumors, and told China Daily that some netizens can't distinguish truth from fiction, "requiring government departments and website companies to take measures". On Monday, the Internet Society of China posted a proposal calling on Internet companies and websites to strengthen self-discipline and prevent the spread of online rumors. In response, three main Internet companies in the country - Sina, Baidu and Tencent - said they will target fake information with advanced technology and invest in manpower to supervise online information. Zhao Zhiguo, deputy director of the Telecommunications Administration under the Ministry of Industry and Information Technology, said stricter self-management of websites will help banish online rumors. "Internet companies should take legal responsibility when operating their websites. They should not become a hotbed for rumors and provide opportunities for fake information," Zhao said, adding they will launch similar crackdowns to close illegal website companies and punish those responsible. Currently, people who make or spread rumors related to terrorism and securities trading, or information affecting State security and companies' commercial reputations, will face criminal punishment. Liu Honghui, a Beijing lawyer specializing in online cases, said he welcomed the government's action to curb online rumors. "Residents used online banks to shop or book flights, which needs a safe platform without fake information," he said. Yu Guofu, another lawyer from Sheng Feng Law Firm, said the key to reducing rumors is netizens themselves. "If micro-bloggers think twice before forwarding information, rumors will decrease." How many websites were shut down before mid-March in the latest crackdown on online rumors?

A. 42
B. 58

Dust on furniture may be bad news for waistlines . But it's far too early to add dusting to a weight-loss plan. Dietary fats and other materials that make up indoor dust can send a signal to human fat cells, telling them to grow. That process, in turn, might slow the body's rate of burning energy. Such changes could add to any weight problems a person might have. "We don't know what that means to long-term health and certain diseases yet," says Heather Stapleton, one of the study's authors. But she notes that her team's findings also raise a question of whether pollutants in dust might play some role in the growing, global problem of obesity . Stapleton and her colleagues collected dust from homes and offices. Studies found that some materials in the dust could turn on a protein called PPAR-gamma 1. It's found in many human tissues. Turning this protein on can cause fat cells to grow. Researchers think this protein may be involved in obesity. But a second study now finds evidence that certain fats are mostly to blame. Cooking oils may send out some of these fats into the air, where they eventually find their way into house dust. Or, the authors say, the fats might enter house dust as part of the hair or skin cells shed by people or pets. "While the findings are amazing," says Mitchell Lazar, another study author, "these findings need to be taken as very limited." Indeed, he adds several cautions about how the findings should be understood. "For one thing, people eat these fats in foods all of the time. That is likely to be a lot more than would be consumed from indoor dust," he said. What do we know about PPAR-gamma 1? _
Choices:
A. It comes from dust.
B. It leads to weight gain.
C. It can help get rid of dust.
D. It only appears in human bodies. | B |

Nutrition influences not only students' grades at school but their growth and development. Improper nutrition is one of the causes of childhood obesity. What can you do to help your child avoid childhood obesity? My first piece of advice is to look in your fridge. What are you buying at the grocery store? Think about it: if you don't buy junk food or snacks, your kids won't eat them at home. Now if you're like me -- both of your kids are at school, you'll know you can't police them every second of the day. This is the time when you'll need to talk to your children about their food choices. If you don't know the right food choices, there are so many free resources on-line to guide you. Try new things. I was very surprised to find out my 4-year-old daughter likes balsamic vinegar -- she calls it the "black sauce". She likes to have it with tomatoes and cucumbers. You just never know what your kids might like. Don't get stressed if you can't always prepare something healthy. You may sometimes leave the house and forget to take something out for dinner, or you are running late and there's no time to cook before you have to take one of the kids somewhere. However, you can still make healthy choices while dining out. Many of the fast food restaurants offer fruit and milk instead of soda. I like to buy organic frozen pizzas from the organic market -- for a quick dinner solution . All the ingredients are natural. What I do is to serve the pizza with something raw: lettuce, cucumbers, tomatoes, or fruit to try to give the kids something healthy with that meal. In closing, take baby steps. Don't try to change your family's eating habits in one go, or you'll go nuts. This passage is written mainly to _
Choices:
A. explain why today's kids are overweight
B. tell us the importance of healthy eating
C. give parents some healthy eating tips

mmlu | Question:
Burns can be caused by fire, the sun, chemicals, heated objects or fluids, and electricity. They can be minor problems or life-threatening emergencies. Distinguishing a minor burn from a more serious burn involves determining the degree of damage to the tissues of the body. If you are not sure how serious the burn is, seek emergency medical help. First-degree burns are those in which only the outer layer of skin is burned. The skin is usually red and some swelling and pain may occur. Unless the burn involves large portions of the body, it can be treated at home. Second-degree burns are those in which the first layer of skin has been burned through and the second layer of skin is also burned. In these burns, the skin reddens intensely and blisters develop. Severe pain and swelling also occur. Second-degree burns require medical treatment. Third-degree burns are the most serious and involve all layers of skin. Fat, nerves, muscles, and even bones may be affected. Areas may be charred black or appear a dry white. If nerve damage is substantial, there may be no pain at all. These burns require emergency medical attention. Follow these steps when treating minor burns at home 1) If the skin is not broken, run cool water over the burn for several minutes. 2) Cover the burn with a sterile bandage or clean cloth. 3) Take aspirin to relieve any swelling or pain. Seek emergency treatment immediately for major burns. Before an emergency unit arrives, follow these steps 1) Remove the person from the source of the burn (fire, electrical current, etc.). 2) If the person is not breathing, begin mouth-to-mouth resuscitation immediately. 3) Remove all clothing to stop further burning. If the clothing is stuck to the burn, do not attempt to remove it. 4) Cover the burned area with a cool, moist, sterile bandage or clean cloth. Do not place any creams, ointments or ice on the burned area or break blisters. 5) Monitor the patient for signs of shock, and treat accordingly. Burns are divided into different degrees according to _ .
Choices:
A. what kind of treatment they need
B. what kind of tissue of the body is damaged
C. whether there is pain and what degree of pain there is
D. which layer of skin is burned | D |

Hiking can be a pleasant as well as a not so pleasant adventure. You will have to take a number of measures so that your hike is a pleasant experience. Hiking Tip 1 -- Start Early Most hiking experts hold the opinion that it is rather sensible to start hiking at 3 or 4 in the morning, even if it is a full-day hike. Since most hikes are conducted at high altitudes, starting off early will make sure that you are back down during the afternoon hours. Hiking Tip 2 -- Be Light Since we are anyway talking about the load you will carry, another important hiking tip is to carry fewer loads. If you are going on a hiking trail on a familiar path, you will need reduced survival items, as chance that you will get lost or hurt yourself on these hiking trails is little. Hiking Tip 3 -- Reduce the Number of Breaks Once you start your hike, you should make sure you do not take too many breaks. You will need to maintain a consistent speed and minimize the number of stops which you take. Speed and rest stops help distinguish an inexperienced hiker from an expert hiker. An inexperienced hiker will have bursts of speed and energy and it will be followed by rest stops. This results in slowing down the general speed. Hiking Tip 4 -- Tip for Children Do you plan to take your kids along with you on the hiking trail? Well, then you must be looking for hiking tips for kids! You will have to educate them about nature and also get them into an exercise routine before taking them on a hike. Kids have a tendency to run in the beginning. This exhausts them and they have to be carried, which is certainly not the best of ideas. What should you do if you are going hiking on an unfamiliar trail?
Choices:
A. Carry enough survival items.
B. Keep a high speed.
C. Start hiking in the afternoon.
D. Carry fewer loads. | A |

Teofilo Stevenson was born in 1952 and grew up in a small town in Cuba.He started boxing as a teenager and, when he was 13, went to Havana to train at the national sports complex."I lost 14 of my first 20 fights," said Stevenson."I hated getting hit.What happened was that I decided I hated losing even more."

Many more babies will be born before the Year of the Horse ends, because many couples in China try to avoid having babies in the Year of the Sheep, which starts on Feb 19, 2015. The reason: traditionally it is believed that "sheep babies" lead a difficult and suppressive life. The truth is, there is no evidence to prove that people born with the zodiac sign of sheep are destined for a difficult life. Apple co-founder, the late Steve Jobs, and movie stars Chow Yunfat and Zhang Ziyi were all born in the Year of the Sheep. Superstition, as its dictionary description says, is an unreasonable belief that an object, action or circumstance not logically related to a course of events influences its outcome. Many people regard black cats as unlucky when they are unlucky only for mice. The number 13 is considered unlucky in the West, but it was quite an lucky number in ancient China. The "rich" number " 8 " is viewed as lucky in China, yet it doesn't look different from any other number in the West. But such is the influence of superstition on some people that they undergo cesarean section , even without going into labor, to give birth before the onset of a year they consider unlucky. Doctors warn that premature cesarean section is a violation of the laws of nature which could affect the baby's brains and health, but some people ignore their advice. On the social side, the sudden increase in the number of births in one year will make it even more difficult for children to get admission to schools and drastically raise the demand for jobs when they grow up. Ironically, children born in a baby boom year can become a liability because they will be locked in a tougher competition for educational, natural and material resources. In more sense than one, their competition begins even before they are born, because their mothers have to wait longer for their regular medical check-ups and to secure a bed in a hospital for childbirth. In China where more often than not parents guide (or even force) their children to choose the subjects to study and the vocations to compete for, zodiac signs are of least or no importance. The real important thing is to encourage children to let their imagination fly and develop their unique skills. The writer uses facts from the following fields EXCEPT _ to support his point of view.
Choices:
A. culture
B. science
C. politics
D. economy | C |

A survey shows that the number of fires in government buildings each year is small compared to home fires. This is probably because such buildings are taken good care of and managed. However, at home after work fire safety is your own duty. For most of us who live in high-rise buildings, the safety of you and your family depends on how much you know to do with an emergency . When a fire happens, there is usually little time to decide what to do or how to act. The best thing is to make your emergency plan as soon as possible. Sit down with the family and prepare a careful escape project. Do remember that every fire is _ . Fire and smoke can move very quickly and the situations in any part of the building may change very quickly. Smoke is usually more dangerous than fire. It can spread throughout the building and enter your house when the fire is many floors away. Some information says it is best to leave your house immediately when there is a fire. Others say it is safer to stay there. Which is correct? Usually the best thing to do is to leave the building as soon as possible. However, do not try to leave your house a long time after the fire alarm has sounded. There is a higher chance that heavy smoke has already spread into stairways and hallways. Never travel through smoke. You must stay inside your house and place wet towels at the bottom of the door to stop smoke from entering. Call the Fire Services Department by dialing "119", tell them where you are and then move to the most smoke-free room. Open the window there to let in fresh air if possible. Hang a sheet from the window to show fire fighters where you are. If it is a long time since the fire alarm sounded, the proper thing to do is _ .
Choices:
A. to try to put out the fire
B. to stay inside the house
C. to leave the house at once
D. to sit down with the family | B |

Because of the stress and strains of modern life folks today would rather watch television than get together with neighbors. Their behavior doesn't mirror TV soaps like Coronation Street and East Enders. The Street's Ashley Peacock and Toyah Battersby know all their neighbors. But the Royal Mail survey shows that real-life under35s wouldn't dream of popping next door for a chat or to borrow a cup of sugar. Three out of ten say they wouldn't know their neighbors if they saw them in the street. The same proportion would only offer to help neighbors if absolutely necessary, while thirty-onepercent don't want to get to know them better. Twenty-six percent rarely or never speak to the person next door. Thirty-five percent only talk to neighbors occasionally, and six percent actively dislike them. The older generation are still sociable, with seventy percent of over55s taking time to chat to people next door. The report says: "In the past, the British tradition of village green gossip between neighbors was celebrated worldwide. But there's been a clear shift away from local links by the young generation." Londoners are least likely to be neighbors, with a third rarely or never chatting over the garden fence. People in the Midlands--where 65 percent often speak to their neighbors are most friendly. Sociologist Jane Blakeman said: "People are working longer hours than ever before, and are traveling further to work. It leaves them far less time at home." Gossip among neighbours is still common among _ .

In Google's vision of the future, people will be able to translate documents instantly into the world's main languages with machine logic, not expert linguists, leading the way. Google's approach, called statistical machine translation, differs from past efforts in which it does without language experts who program grammatical rules and dictionaries into computers. Instead, they feed documents humans have already translated into two languages and then rely on computers to decide patterns for future translations. Though the quality is not perfect, it is an improvement on previous efforts at machine translation, said Franz Och, 35, a German who heads Google's translation effort at its Mountain View headquarters south of San Francisco. "Some people who have been in machine translations for a long time see our Arabic-English output, and then they say, that's amazing; that's a breakthrough ." Said Och. "And then other people who have never seen what machine translation was read through the sentence and they say, the first mistake here in Line Five-it doesn't seem to work because there is a mistake there." But for some tasks, a mostly correct translation may be good enough. Speaking over lunch this week in a Google cafeteria famed for offering free, healthy food, Och showed a translation of an Arabic Web news site into easily digestible English. Two Google workers speaking Russian at a nearby table said, however, that a translation of a news site from English into their native tongue was understandable but a bit awkward. Och, who speaks German, English and some Italian, feeds hundreds of millions of words from parallel texts such as Arabic and English into the computer, using United Nations and European Union documents as key sources. Languages without considerable translated texts, such as some African languages, face greater obstacles. "The more data we feed into the system, the better it gets." said Och, who moved to the United States from Germany in 2002. The program applies statistical analysis, an approach he hopes will avoid diplomatic embarrassing mistakes in diplomatic situations, such as when Russian leader Putin's translator annoyed then German Chancellor Gerhard Schroeder by calling him the German "Fuhrer ("leader" in English)," which is forbidden in that context because of its association with Adolf Hitler. "I would hope that the language model would say, well, Schroeder is...very rare but Bundeskanzler Gerhard Schroeder is probably 100 times more frequent than Fuhrer and then it would make the right decision." Och said. Statistical analysis in this passage is conducted by _ .
Choices:
A. hiring people who speak different languages
B. counting how frequently a word is used in the language
C. using the computer with its own grammatical rules

If you go to an American middle school on Wednesday morning, you will hear kids talking about the American idol show from the night before. Some have called it the most influential show in the history of television. American Idol has been extremely successful in the country since 2002. The show was number one for six years! The most popular episode had nearly 38 million _ . But why is the show so popular? The idea of the show is this: everyday people get a chance to show their singing talents to the world and become an "American Idol", a famous pop star. Anyone in the country(between the ages of 15 and 28) can have a try--a chance of becoming world famous. In fact, everyday people are the ones who are allowed on the show.

mmlu | Question:
EACH of us fails from time to time. If we are wise, we accept these failures as a necessary part of the learning process. But all too often we convey to our children either by words or by actions that failure is something to be ashamed of, that nothing but top performance meets our approval. Donnie was my youngest third-grader. His fear of failure kept him from classroom games that other children played excitedly. He seldom answered questions - he might be wrong. He seldom finished his work because he repeatedly checked with me to be sure he hadn't made a mistake. I tried my best to build his self-confidence. But nothing changed until midterm, when Mary Anne, a student teacher, was assigned to our classroom. She was young and pretty, and she loved children. My pupils, Donnie included, adored her. But even enthusiastic, loving Mary was _ by this little boy who feared he might make a mistake. Then one morning we were working math problems. Donnie had copied the problems with painstaking neatness and filled in answers for the first row. Pleased with his progress, I left the children with Mary. But when I returned, Donnie was in tears. He'd missed the third problem. Mary looked at me in despair. Suddenly her face brightened. From the desk we shared, she got a canister filled with pencils. "Look, Donnie," she said, "I've got something to show you." She removed the pencils and placed them on his desk. "See these pencils, Donnie?" she continued. "They belong to Mrs. Lindstrom and me. See how the erasers are worn? That's because we make mistakes too. Lots of them. But we erase the mistakes and try again. That's what you must learn to do, too." She kissed him and continued: "I'll leave one of these pencils on your desk so you'll remember that everybody makes mistakes, even teachers." Donnie looked up with love in his eyes and just a glimmer of a smile. The pencil became Donnie's prized possession. That, together with Mary Anne's frequent encouragement and praise for even Donnie's small successes, gradually persuaded him that it's all right to make mistakes - as long as you erase them and try again. Which of the following words best describe Mary Anne as she is shown in the article?
Choices:
A. Patient and inspiring.
B. Creative and modest.
C. Determined and strict.

Not all think laughter is the best medicine, but it seems to help.So scientists carried on a new study of diabetes patients who were given a good dose of humor for a year to prove it. Researchers divide 20 high-risk diabetic patients into two groups.Both groups were given standard diabetes medicine.Group L viewed 30 minutes of humor of their choice, while Group C, the control group, did not.This went on for a year of treatments. By two months into the study, the patients in the laughter group had lower level of the hormones epinephrine , considered to cause stress, which is known to be deadly.After the 12 months, _ rises 26 percent in Group L but only 3 percent in Group C.In another measure, C-reactive proteins, a maker of heart disease, drop 66 percent in the laughter group but only 26 percent in the control group. "The best doctors believe that there is a physical good brought about by the positive emotion, happy laughter," said study leader Lee Berk of Loma Linda University.And other research has found that humor makes us more hopeful.Still, more study is needed, Berk said.The research by Berk found that humor can bring about similar changes in body chemistry, which was proved in the new study.The research result will be presented this month at the meeting in the US.Research at the University of Maryland School of Medicine shows that laughter causes the inner lining of blood vessels to expand, increasing blood flow in a way thought to be healthy. "Lifestyle choices have an important effect on health and these are choices which we and patients should pay attention to, rather than prevention and treatment," Berk said in a statement this week. After 12 months into the study, _ .
Choices:
A. C-reactive proteins increase 66 percent in Group C
B. the level of the hormones epinephrine stays the same in both groups

Chinese scientist Tu Youyou on October 5 won the Nobel Prize in physiology or medicine amongst a trio for discovering parasite therapies . 85-year-old Tu is awarded this world-renowned prize for her contribution to reducing the death rate of malaria, minimizing patients' suffering and promoting mankind's health. This is what science is all about. Tu's finding has saved millions' lives during the 40 years. This also proves the value of her research product. The reward is never too late in that aspect. The moment of joy and satisfaction came when she discovered the artemisinin( ) after all kinds of failures in experiments. As the first Chinese mainland Nobel Prize Winner of natural science award, Tu's winning completely surprised Chinese people, who have long been wondering when the first Chinese Nobel laureate in natural science would appear. Let's backtrack to 40 years ago. Tu accomplished the breakthrough findings without access to any advanced equipment, communication with outside world and papers to research. However, over the 40 years, improvements and innovations have transformed everything. Nowadays, Chinese scientists have the passion to invent. As Premiere Li Keqiang mentioned in his letter, "Tu's winning the prize signifies China's prosperity and progress in scientific and technological field". Tu's record-breaking winning serves as a reminder to those who are too eager for instant success. Science is never about instant success. There is no way to measure how much you spend on scientific research and compare it with how much reward you get. Which magazine this passage may be mostly selected from?

What is the definition of "happiness?" Is it material wealth filled with fancy cars, a dream house or jewelry? Or does happiness simply mean having a roof over your head? Food in the fridge? Having a swimming pool? A designer Gucci bag? Love? Money? A perfect job? Do you recall a time----let's say when you were about 5 years old-----what defined happiness back then? Was it getting a puppy for Christmas? Or maybe, you were a child of divorce; and all you wanted was for Mom and Dad to get back together again? Then as you got older, you were hoping that someone would ask you to the party that would have made your day. During college, good grades made you happy, but it was short-lived. Because in the real world, you had to look for a job, and competition was fierce. But then, you got a perfect job, could you be happy? We like having and accumulating things. We work so we can pay our rents, credit card debts, school loans, car payments... The list goes on and on. And at some point, we realize that apart from having most of what we want, we still aren't happy. Now since we've learned to adapt to new standards which we've created for ourselves, we find that we have less time, less patience, less sleep, which leads to more stress and more anxiety. Therefore, don't stupidly make a conclusion that happiness is just based on "things". Sometimes, we trade our lives for not only basic necessities, but for excessive items and services as well. Certainly, you've heard of individuals trying to "find themselves", or to "rediscover themselves". But the point has been missed: happiness is already there. Disappointments and tragedies in life will come and go, but happiness never leaves you. We can lose our jobs, but be grateful for those who love us. We can lose our homes to nature, but be thankful to be alive. If we think we are happy, we are indeed happy. Happiness is merely a perception of each individual. Happiness is part of love, and love is an ocean. Go dive in and get some, and then share it with everyone, which can be an endless supply. But sharing happiness with people around demands skilful techniques. The author puts forward a lot of questions to _ .

Chocolate was a box turtle. Lauren found her one day on the side of the road, hiding in her old, worn shell, frightened by the cars going by. Lauren picked Chocolate up to help her cross the street, because Lauren knew that turtles are very slow and cars are very fast. After Lauren got Chocolate to the other side of the road, Chocolate peeked her head out of her shell and looked at the little girl. Lauren saw that not only was Chocolate's shell worn, one of her eyes was shut. Lauren thought Chocolate needed more help from her, so Lauren took the turtle home.

My Garden -----by Nelson Mandela In early 1977, the authorities announced the physical labour and arranged some kind of work for us to do in the courtyard. The free time also allowed me to hunt what became two of my favorite hobbies in Robben Island---gardening and tennis. To survive in prison, one must develop ways to take satisfaction in one's daily life. One can feel fulfilled by washing one's clothes so that they are particularly clean. Just as one takes pride in important tasks outside of prison, one can find the same pride in doing small things inside prison. Almost from the beginning of my sentence on Robben Island, I asked the authorities for permission to start a garden in the courtyard. For years, they refused without offering a reason. But finally they gave in, and we were able to cut out a small garden in the prison. The soil in the courtyard was dry and rocky. In order to start my garden, I had to remove a great many rocks to allow the plant room to grow. The authorities supplied me with seeds. At first, I planned tomatoes and onions, because these plants did not require rich earth or constant care. The early harvests were poor, but they soon improved. I began to order books on gardening. I studied different gardening techniques and types of fertilizers . For a time, I tried to grow peanuts, and used different soils and fertilizers, but finally I gave up. It was one of my few failures. A garden was one of the few things in prison that one could control. The processes of planting a seed, watching it grow, taking care of it and then harvesting it offered a simple but long-lasting satisfaction. The sense of being the owner of the small patch of earth offered a small taste of freedom. Why did Mandela wash his clothes especially clean although he was in prison?
Choices:
A. To show he could do it as well as others.
B. To get some sense of pride and satisfaction from it.
C. To show others that he preferred to be clean.
D. To gain the authorities' permission to start a garden. | B |

Since Edmund Hillary and Tenzing Norgay climbed Mount Everest, Mount Qomolangma's peak is no longer a lonely place and is turning into a trash heap. So far, more than 350 climbers have successfully reached the peak. And they have complained about waiting for hours in the bottlenecks on the way to the peak, a situation that isn't just uncomfortable -- it's cold and windy up there -- but downright dangerous. If bad weather strikes, climbers can and do die. As a matter of fact, the dangerous crowds aren't the only problem on Qomolangma. All those climbers need to bring a lot of _ --and much of them ends up being left on the mountain, sometimes even the peak itself. Mount Qomolangma is becoming the world's largest dump. Here's mountaineer Mark Jenkins writing in National Geographic about the state of Qomolangma: "The two standard routes, the Northeast Ridge and the Southeast Ridge, are disgustingly polluted with oxygen cans and torn tents everywhere." But the good news is that some mountaineers are taking it upon themselves to clean up Qomolangma. Mountianeer Paul Thelen and his friend Eberhard Schaaf are part of the annual Eco Everest Expedition, which has been cleaning up rubbish from base camps to the peak since 2008. So far they've collected over 13 tons of garbage. Some of that rubbish is even being used for a higher purpose. As part of the Mount Everest 8844 Art Project, a group of 15 artists from Nepal collected 1.5 tons of garbage brought down the mountain by climbers. They've transformed the cans and oxygen tanks--and in one case, part of the remains of a helicopter--into 74 pieces of art that have already gone on exhibition in Nepal's capital. Part of the profit from sales will go to the Everest Peakers Association, which has helped collect tons of rubbish on the slopes of the mountain. What can be the best title for the text?

Do you suffer from cybersickness? The rise of mobile phones has been blamed for a number of social ills, but your smart phone may also be making you physically sick as well. Scientists have identified a condition called "cybersickness", which they say is the digital version of motion sickness. The phenomenon, which affects up to 80 percent of the population who own smart phones or tablets, leads to feelings of sickness and unsteadiness. It is caused by seeing fast motion on a screen, which covers anything from a car chase in a film to scrolling through web pages on your phone. The more realistic the visual content appears to you, the higher your chances of getting cybersickness are . The condition was identified in a piece in the New York Times in which British and US experts said that it needed solving. Motion sickness leaves sufferers feeling ill because they feel movement in your muscles and your inner ear but do not see it. The mismatch in digital sickness is the opposite--you see movement on the screen but do not feel it. The effect is the same and the symptoms include a headache, wanting to throw up, confusion and the need to sit down. Often cybersickness shows itself in a subtle way and sufferers put it down to stress or eyestrain. Steven Rauch, a professor of otolaryngology at Harvard Medical School, said: "Your sense of balance is different from other senses in that it has lots of inputs. When those inputs don't agree, that's when you feel dizziness and sickness. " Some studies that have been carried out into cybersickness found that women are more _ than men, the New York Times reported. Those who have Type A' personalities--meaning they are confident and determined--are more likely to suffer from cybersickness as well. Among those who have reported experiencing the condition have been video gamers who spend hours playing fast paced games. Engineers at Oculus VR, the virtual headset manufacturer, have admitted that digital motion sickness is one of their biggest problems. This passage is most probably _ .

Coupons to spend "How did you spend your coupons?" On their first day back to school, many students in Hangzhou greeted each other this way. The coupons referred to the 100 yuan coupons each student received form the city government before the Spring Festival holidays. Over 260,000 primary school and middle school students were given coupons. They could use them in local stores and supermarkets, or to see movies and buy books. The same coupons have also been given to low income families in Hangzhou. Other cities, including Chengdu and Nanjing, also gave coupons to their citizens. More cities are expected to follow their lead. Why are local governments doing this? These programmes are all part of a broader effort in China to increase domestic demand in the face of the global financial crisis. The crisis has seriously affected China's exports and investments . Many factories in southern cities have been closed down. Some companies are laying off workers or reducing their pay. The stock market and real estate market have been falling. In a time of financial crisis, people usually respond by saving money. They are uncertain about the future and are afraid that more difficult times may be ahead. Now many people are choosing not to spend money carelessly. Major chain stores have seen a sharp slowdown in sales, analysts say. But spending keeps an economy healthy. If people don't spend, there will be too many products in the market. Then shops will stop buying products from factories. When factories receive no orders, they close down. The workers there accordingly lose their jobs. Also, if people don't spend, the service industry suffers. The total result is that the whole economy breaks down. Issuing coupons is a practical and effective way to increase domestic demand in the current situation, said Jiang Zengwei, vice-minister of China's Ministry of Commerce. Hangzhou reported a rise in customers in local markets during Spring Festival holiday. However, issuing coupons is only a temporary measure. To increase consumers' confidence, the government needs to establish a sound secure social system in the long term. When people don't have to worry about education, health care and their pension, they will be more willing to spend instead of saving. Why are local governments issuing coupons?
Choices:
A. To increase domestic demand in the face of the global financial crisis.
B. To enable students to use them in local stores and supermarkets, or to see movies and buy books independently.
C. To help those low income families in the global financial crisis.
