mmlu | Question:
The loneliest chimp in the world just got the best surprise--a hug from a new friend.Ponso has been by himself for nearly three years,finding himself alone after his wife and children died on the island where they were abandoned by a medical testing company many years ago. For years a nearby villager named Germain has been Ponso's only company,visiting him so often to bring bananas and bread--the chimp's only source of food on the tiny island.It was clear how much Ponso missed companionship when he was recently visited by Chimpanzee Conservation Centre Director Estelle Raballand.The chimp immediately embraced Estelle Raballand in a huge hug and laughed as she reached out for him,with his smile from ear to ear. For those who know Ponso's backstory,his immediate ease and trust in humans might be surprising.Ponso was one of 20 chimps,all between the ages of 7 to 11 years old,relocated to an island off the Ivory Coast after being used for testing by the New York Blood Centre.After the tests were completed in 2005,the lab reportedly transferred the chimps to a string of islands,occasionally dropping off food and water because there was none in the chimps' new homes. Disease and hunger soon left only Ponso,his mate and their two children standing.But at the end of 2013 they died within days of each other and Ponso was now completely alone. A group called SOS PONSO is trying to raise money for the poor lonely chimp,already achieving its goal of $20,000--all of which will be used for Ponso's care. What can be inferred from the text?
Choices:
A. Germain won't visit Ponso any more.
B. A new lab will be built on the island.
C. Many people show concern for Ponso.
D. More chimps will be brought to the island. | C |

One summer when I was sixteen, I planted a vegetable garden. I wanted a bunch of different vegetables, so I planted seven tomato plants, three pepper plants, six corn plants, and two cucumber plants. My mom loves zucchini so I also planted ten zucchini plants. I watered the garden daily with a watering can. When weeds started to take over, I pulled them back. About a month in, I started getting fresh vegetables every day. I walked to the garden with a big basket every morning and picked the vegetables that were ready. Sometimes I ate them right off the vine. One day I walked down to the garden and saw that the zucchini plants were taking over. Each of my ten plants had many zucchini, giving me hundreds of zucchinis each week. I didn't know what to do with the zucchini so I gave some to my neighbor. I gave some to my parents to take to their friends. Then I went door to door and gave zucchini to everyone in the neighborhood. Who did I give the zucchini to?
Choices:
A. my neighbors and my friends
B. my neighbors, my parents' friends, and everyone in the neighborhood

A cancer-stricken British teenager said on Thursday she had been moved by messages of support from around the world after writing an online "Bucket List" of things she wanted to do before dying. Alice Pyne, 15, created an Internet blog in which she described her fight against a cancer of the white blood cells. "I've been fighting cancer for almost four years and now I know that the cancer is gaining on me and it doesn't look like I'm going to win this one," she wrote. For her list, at the site www. alicepyne. blogspot. com, she has included making everyone sign up to be a bone marrow donor , swimming with sharks, meeting boy band Take That and getting a purple iPad computer. Messages of support and offers of help quickly flooded her webpage and it became one of the most talked about subjects on Twitter. "Oh dear! And I thought that I was just doing a little blog for a few friends!" she wrote after her site attracted huge attention. "Thank you so much for all your lovely messages to me." Alice, who lives with her family in the northwest English town of Ulverston, said the manager of Take That had arranged for her to see the band after reading her blog. A group of local lawmakers have also made efforts with the Anthony blood cancer charity to encourage people to join its stem cell projects. About Alice Pyne's "Bucket List", which is NOT true?

mmlu | Question:
Yawning sends out certain messages -either "Oh,this movie is so boring" or "I probably need to get some sleep". But did you know that a yawn can also help your brain to cool down when it is overheated? A new study, led by a research team at Princeton University, has indicated that yawning could be the brain's natural way of regulating temperature. People yawn more often when the temperature outdoors is lower than their body temperature but are less likely to yawn when it is hotter outdoors, according to Sciencedaily. com. The research team did an experiment on 160 people, 80 in summer and 80 in winter, to examine how often they yawned at different air temperatures. The study found that people yawned more often in winter than in summer. Scientists say that when the air temperature is lower outside the body, there is heat exchange between the overheated brain and the cool air. But when the air temperature is higher than or equal to the body, people are less likely to yawn because the hot air they breathe in will make the brain even hotter. When people yawn, their jaw is also stretched,which increases blood flow and may also help cool the brain The study showed that the amount someone yawned could be related to the amount of time they spent outside. The longer they spent outside in summer, the less they yawned. Nearly 40 percent of participants yawned within their first five minutes outside, but after that the percentage was reduced to less than 10 percent. However, the result was the opposite in winter. The number of people who yawned increased when they spent more than five minutes outdoors. But the change was only slight compared to summertime. According to Gallup, this is the first report to show that yawning frequencies change depending on season. This could help us to understand better the way our brains work. It may also help us understand the reason why frequent yawning can sometimes be a sign of brain disease. The purpose of the experiment is _ .
Choices:
A. to find the frequency of people's yawning
B. to indicate brain can regulate temperature naturally
C. to prove people yawn in winter and in summer equally
D. to show the real reason why people yawn | A |

mmlu | Question:
Should people be allowed to use cellphones while driving? Alejandra Pachecho from Venezuela: No. Why not? That is because in this world some people drive very crazily. Also, most people who use cellphones to talk in the car usually pay more attention to what they are talking about than to driving. One of the reasons that I feel this way is that ny friend had a car accident while using a cellphone. He lost his life and his friends did, too. Rodrigo Cruz from Colombia: That depends. The a dvantages of using a cellphone while driving are that you can call the police if there is a car accident, call for help when somebody's car breaks down, and call when somebody needs something before arriving home or at the office. The disadvantages is that people get distracted when they are driving at the same time they are talking on a cellular phone. It can cause car accidents. Carl Khalid from Saudi Arabia: No. I would recommend if you want to use a cellphone while you're driving, pull over and take your time. You will avoid a lot of trouble. There are many advantages of using cellphones in cars. In emergencies such as accidents, a flat tire or engine problem, the cellphone is useful for calling 911 for help. Using the cellphone while driving can save time, but using it while driving can alsocause a lot of problems such as missing a red light or signs, not observing cars, or not paying attention to the speed limit. It causes a lot of problems. All these problems could cause loss of concentration. Mirna Hazim: Yes. A cellphone is helpful; it is one of the most important communication devices. For example, if you want to talk with somebody for an important reason, you can. One time when I was coming back from work at 10 o'clock at night, I had a problem with my car. It wouldn't move. I was scared to go into a store to call my brother because I didn't know the places there. I thought it could be dangerous. That night, I found out that owning a cellphone is important. What do you think of cellphone? Send your opinion to our website. Which of the following groups have the same view about using cellphones while driving?

mmlu | Question:
December usually marks the start of humpback whale season in Hawaii. But experts say the animals have been slow to return. The giant whales are an iconic part of winter on the islands and a source of income for tour operators. But officials at the Hawaiian Islands Humpback Whale National Marine Sanctuary said they've been getting reports that the whales have been difficult to spot so far. "This isn't a concern. But it's of interest. One theory was that something like this happened as whales increased. It's a product of their success," said Ed Lyman. He is a Maui-based resource protection manager and response coordinator for the sanctuary. "What I'm seeing out there right now is what I expected a month ago," said Lyman. He said he was surprised by how few of the animals he saw while responding to a call about a distressed calf on Christmas Eve. "We've just seen a handful of whales." It will be a while before officials have hard numbers. That is because the annual whale counts don't take place until the last Saturday of January, February and March. This is according to former sanctuary co-manager Jeff Walters. "They don't necessarily show up in the same place at the same time every year," Walters said. More than 10,000 humpback whales make the winter journey from Alaska to the warm waters off Hawaii. There, they mate and give birth. Lyman said the whales' absence could just mean they're spending more time feeding in northern waters. That's possibly because of El Nino disruptions. Or it may be because their population has gone up. "With more animals, they're competing against each other for that food resource, and it takes huge energy reserves to make that long migration over 2,000 miles," he explained. What is the passage mainly about?
Choices:
A. The migration habit of whales.
B. Why the whales are slow to return.
C. How El Nino slows whale migration down.
D. Worries about the slowdown of whale migration. | B |

mmlu | Question:
The British are being encouraged to holiday at home as a major tourism drive offering Olympic themed discounts is launched next week. A new campaign offering 20. 12% discounted bills at participating venues will be announced publicly for the first time by Culture Secretary Jeremy Hunt on Wednesday to encourage "staycations". The scheme includes hotel accommodation, meals, guided tours and entry to attractions, with discounts funded by the industry. Government officials said more than three million hotel rooms were already lined up under the project, which is being backed by a range of companies, including Butlins. Attractions, such as the London Eye and Alton Towers, are also taking part. Reduced prices will also be offered on stays on the Royal yacht Britannia, now harboring in Leith, Edinburgh, and visits to Chatsworth, the historic house in Derbyshire. Tourists will be able to take advantage of the discount by using a dedicated website before the end of the Paralympics on September 9 to make bookings for this year and 2013. Mr. Hunt said, "With the Diamond Jubilee and the 2012 Olympic Games, this year is the perfect opportunity for more of us to holiday in the UK " Mr. Hunt has travelled the UK, urging companies to take part in the scheme, telling them, _ We will never have a year like 2012 to show the world that this is, quite simply, the most exciting, vibrant, cosmopolitan city on the planet. The unavoidable complaints in the run up to an Olympics must not cloud the scale of the opportunity --including our biggest ever tourism marketing campaign to make sure we get a lasting benefit from being in the global spotlight. " The scheme will be promoted by a PS3 million television advertising campaign -- the first of its kind in the UK. The government hopes the " Holidays at Home are Great" campaign -- launched by Visit England -- will create 12, 000 jobs, create 5.3 million extra short overnight breaks, and generate PS480 million in extra spending over three years. What Mr. Hunt said indicates that _ .
Choices:
A. he has no interest in the scheme
B. he supports the idea of staycation
C. he doubts the benefit of the scheme
D. he cares most about London tourism | B |
mmlu | Question:
Is war unavoidable? Can war be prevented? History tells that there were wars, great or small, in every century, in every decade. Throughout the ages, from the Stone age to the Atomic Age, men have been fighting, first with swords and shields , then with guns and cannons, and now, hydrogen bombs and missiles are used for military purpose. But, in spite of all these, it is still my belief that war can be prevented and peace can be won, but it requires the effort of every one of us. I am sure that we would not like to experience another world war. If it ever happens, two-thirds of the world and much of the civilization which men have gained through time, patience and effort will be destroyed. Will then the remaining one-third of the world be able to survive on its own? Our task now is not to blame the past, but to plan for the future. If there is peace in the world, men can use their rockets to explore the mystery of space, their submarines to explore the depth of the sea, their missiles to deliver mails and their fine equipment to penetrate the jungles of Africa, instead of using them military. Governments can use their money to build more schools, so that more children can be educated to be useful citizens. Scientists can use atomic energy to propel steamships and planes. They can also design new machines to increase the production of goods and thus improve the way of living of the people. How can a peaceful world be achieved? It requires, in my opinion, the understanding and friendship between all people from all nations. Let no one suffer discrimination by reason of color, race, religion, or national origin. Let the rich support the poor and the strong help the weak. We know that neither peace nor such a dream world can come true in a day or a month. It may even take decades or centuries. But let us plan and begin now. Which word can best describe the writer's picture of the future of the world?
Choices:
A. Optimistic
B. Pessimistic
C. Imaginative
D. Disappointing | A |

mmlu | Question:
The Erie Canal was the first important national waterway built in the US. It crossed New York from Buffalo on Lake Erie Troy to Albany on the Hudson River. It joined the Great Lakes with the Atlantic Ocean. The canal served as a route over which industrial goods could flow into the west, and materials could pour into the east. The Erie Canal helped New York develop into the nation's largest city. The building of the canal was paid for entirely by the state of New York. It cost $ 7 143 789, but it soon gained its price many times over. Between 1825, when the canal was opened, and 1882, when toll charges were stopped, the state collected $121 461 891. For a hundred years before the Erie was built, people had been talking about a canal which could join the Great Lakes and the Atlantic Ocean. The man who planned the Erie Canal and carried the plan through was De Witt Clinton. Those who were against the canal laughingly called it "Clinton's Ditch ". Clinton talked and wrote about the canal and drew up plans for it. He and Governor Morris went to Washington in 1812 to ask for help for the canal, but they were unsuccessful. Clinton became governor of New York in 1817, and shortly afterwards, on July 4, 1817, broke ground for the canal in Rome, N.Y. The first part of the canal was completed in 1820. As the canal grew, towns along its course developed fast. The length of the canal is 363 miles. Which of the following is true according to the passage?
Choices:
A. The Erie Canal brought profits of over $114, 000, 000.
B. It's 363 miles from the Great Lakes to the Atlantic Ocean.
C. The West was more advanced than the East when the canal was built.

"Today is Mom's birthday, Mosh," Nick said. "Let's make her favorite banana bread and surprise her."Nick took out a cookbook. "I'll read the recipe, and you follow it. Get out a bowl and a spoon while I turn on the oven." Nick read from the cookbook. "First, mash the bananas in the bowl." The robot put the bananas into the bowl and was going to mash them with its hands. "Stop!" Nick said. "Let's try this again. Peel the bananas, put them in the bowl, and mash them with the spoon." Nick watched when Mosh peeled the bananas and put the peel into the bowl. Again, Nick told Mosh to stop. Then he showed the robot which part of each banana should go into the bowl. Then Nick read, "Add the eggs. No, wait," he said right away. Nick cracked the eggs into the bananas. "Last, add flour , milk and sugar," Nick said. "Mix everything together. Then pour the batter into the bread pan." Mosh followed Nick's orders while Nick read the cookbook. "I'll put this in the oven," Nick picked up the pan. Just then Kelly came into the room. "What happened in here?" she felt surprised. Nick answered, "Mosh and I are making banana bread for Mom's birthday. It is a lot of work, but I think she will be surprised." "If you want it to be a good surprise for Mom," Kelly laughed, "you need to give Mosh one more order. Clean up!" Why did Nick decide to make banana bread?

A. Because his robot liked it a lot.
B. Because it was his favorite food.
C. Because it was his mother's birthday.
D. Because no one else cooked dinner for him. | C |
mmlu | Question:
Scientists have always been interested in the high level of organization in ant societies. American researchers have watched ants build life-saving rafts to keep afloat during floods. They also have documented how ant colonies choose their next queen--the female whose job is to produce eggs rather than seek food for others. New technology is helping to improve researchers' understanding of the insects. But there is still a lot to be learned. Fire ants living in Brazilian forests are perfectly at home in an environment where flooding is common. To save themselves, the insects connect their legs together and create floating rafts. Some ant rafts can be up to 20 centimeters wide. David Hu who is a mechanical engineer with the Georgia Institute of Technology, also known as Georgia Tech, says, "If you have 100 ants, which means 600 legs, 99 percent of those legs will be connected to a neighbor. So they're very, very good at maintaining this network." David Hu and other Georgia Tech researchers want to study ants and the secret of their engineering. They freeze ant rafts and then look at them with the help of computed technology, or CT, images. The pictures show that larger ants serve in central positions to which smaller ants hold. The larger ants form pockets of air that keep the insects afloat. Scientists say small robots or materials that can change shape could be programmed in a similar way, working towards a shared goal. Researchers at North Carolina State University are also studying ants. They examined how Indian jumping ants choose the leader of the colony when they lose their top female or queen. The author takes fire ants as an example to tell us .

Tu Youyou, the 85-year-old Chinese pharmacologist ,received the Nobel Prize for medicine in Stockholm on December 10,2015. Tu is the first Chinese Nobel winner in physiology or medicine. Also, in 2011, she became the first Chinese person to receive the US-based Lasker Award for clinical medicine. Based on a fourth-century Traditional Chinese Medicine (TCM) text, together with her team, she managed to get artemisinin from sweet wormwood through trial and error and developed an important drug that has significantly reduced death rates among patients suffering from _ . Tu delivered a speech titled Artemisinin is a Gift from TCM to the World. She has urged more research into the benefits of traditional Chinese medicine and called for joint efforts worldwide to fight against malaria and develop more potential uses for TCM, which she called a "great treasure" with thousands of years' history and empirical knowledge. She said that by combining TCM with modem scientific technologies, "more potential can be discovered in searching for new drugs " . According to the WHO, more than 240 million people in sub-Saharan Africa have benefited from artemisinin, and more than l. 5 million lives are estimated to have been saved since 2000 thanks to the drug. Apart from its contribution to the global fight against malaria, TCM played a vital role in the deadly outbreak of SARS across China in 2003. Besides treating viruses, TCM has been most effective in diagnosing diseases, cultivating fitness, treating difficult multisource illnesses, and using nonmedical methods such as acupuncture and breathing exercises. However, TCM, which is based on a set of beliefs about human biology, is seldom understood or accepted by the West. Tu's success will bring more recognition and respect for TCM, experts say. The Western world should learn to appreciate the value of the treasures of TCM, which will lead to more basic scientific research into ancient TCM texts and ways to explore research findings worldwide. What can we learn from the passage?
Choices:
A. This success may encourage Easterners to learn more about Chinese medicine.
B. Nothing remains to be done in researching into TCM theories and texts.
C. More research into the value of TCM should be carried out worldwide.
D. TCM only contributes to the fight against malaria and SARS in China. | C |
mmlu | Question:
Decision-making can be extremely difficult. Decision-making styles are significantly different in different cultures. In any approach to a problem and in any negotiations, the Western world turns to the"I to you" approach while Japan,the "you to you" approach. The former means both sides present their arguments openly from their own point of view. Naturally, often comes a conflict situation, which Westerners are very skillful in dealing with.The latter is based on each side trying to understand the other person's point of view. Thus, the direction of the meeting is a mutual attempt to reduce confrontation and achieve harmony. Besides, Western decision-making goes mostly from top management and often does not consult middle management or the worker. However, in Japan great consideration is given to the thoughts and opinions of everyone at all levels. Based on "bottom-up direction", ideas can be created at the lowest levels, travel upward through an organization and have an effect on the final decision. Difference in decision-making also comes from different communication styles. The Japanese business person works to achieve harmony, even if the deal fallsthrough, and will spend whatever time is necessary to determine a "you to you" approach, communicating personal views only indirectly. They put a thorough job above the Western deadline approach. So the Japanese are thorough in their meetings. Thus Americans are often annoyed by the many meetings in many Japanese businesses. But where the American is pressingfor a specific decision, the Japanese is trying to think up a rather broad direction. On the other hand, once a given agreement is made, it is the Japanese who sometimes wonderat the slow pace in which Westerners carry out the decision. The Japanese are eager to move forward and Westerners, perhaps, fall behind as they take the time for in-depth planning. The author's attitude towards Japanese decision-making is _ .

My 13-year-old daughter Lisa remembers birthdays, makes people cards when they are sick, and sends encouraging notes written in colored pens in her neat, artistic hand. One day I got a call from her principal, "I called to tell you that in 20 years of teaching I have seen nothing like what Lisa did today", he said I held my breath again as I thought, my Lisa? My sweet daughter? She must be the wrong kid. What could she have done? My silence made him go on. "I've never seen a student do anything so nice for anyone who needed it more." "What did she do?" I asked. He explained to me about the cupcakes . When Lisa came home from school that afternoon, I told her the principal from her school had phoned me. "Yeah", she answered, "I got called out of math class to go to his office. Everyone thought I was in trouble, but he just wanted to know what was going on at lunch." Lisa and Ashley had sat with Jordan, a boy who is in special classes. They talked about birthdays, and Lisa asked Jordan when his birthday was. He told her it was coming up but that he lives in a group home and they don't celebrate birthdays there. "I remembered his birthday was today, so I made the cupcakes yesterday," Lisa explained. "Ashley bought a two-liter bottle of soda and some birthday cups, plates, and napkins left over from her little brother's party, and we got some other kids together at lunch today to sing 'Happy Birthday' to Jordan." "The principal wanted to know why they were having a birthday party for Jordan at school. When they told him, he just shook his head, took off his glasses, and rubbed his eyes," Lisa told me. "Finally, he said he was going to tell my parents that I wasn't in trouble, he was proud of what I did, and I could go back to math class." How different my daughter was from me. Better, in fact! I wouldn't have ever known how to help out disadvantaged kids like that. But my wise daughter knew how-- all it took was cupcakes and adventurous , independent , kind spirit. What can we know from the school principal's phone call?

The Linguistic Habits of a New Generation In the year of 1914 a young girl named Monica Baldwin entered a convent ,remaining there until 1941 when she returned to the outer world. During these twenty-eight years wars and revolutions had come and gone in Europe. Her uncle, Stanley Baldwin, had led his country for some time. Technical developments had changed the conditions of everyday life almost beyond recognitions, but all these events had left as a matter of fact untouched the small religious community to which she had belonged. In 1949 Miss Baldwin published her impressions of those bewildering years of her return to a world in which the motorcar had replaced the horse and carriage and where respectable women showed their legs and painted their faces. Yet it was not only these odd sights that surprised her, for she was more puzzled by what she heard. During a railway journey the term "luggage in advance" meant nothing to her, so in desperation she asked the porter to do as he thought best. Reading the newspapers made her feel very stupid, because the writers of reviews and leading articles used words and phrases such as Jazz,prefix = st1 /Hollywood, Cocktail and Isolationism. These and many others were quite incomprehensible to Miss Baldwin, who was really bewildered when friends said: "It's your funeral or Believe it or not." This is a rare and valuable reminder to the rest of us that the English language does not stand still. All language changes over a period of time for reasons which are imperfectly understood. Or rather since speech is really a form of human activity, it is more exact to say that each successive generation behaves linguistically in a slightly different manner from its predecessors(,). In his teens the young man likes to show how up-to-date he is by the use of the latest slang , but as the years go by some of his slang becomes standard usage and in any case he slowly grows less receptive to linguistic novelties(,),so that by the time he reaches his forties he will probably be unware that some of the expressions and pronunciations now being used were frowned upon by his own parents. In this respect language is a little like fashions in people's dress. The informal clothes of one generation become the everyday wear of the next, and just as young doctors and bank clerks nowadays go about their business in sports jackets, they are allowed into their normal vocabulary expressions which were once limited to slang and familiar conversation. By the time a man is forty, he will_.
Choices:
A. be speaking the same language as his parents do
B. have changed his way of speaking
C. not use the slang he liked to use when young
D. be using less new slang in speech and writing | D |

More than a hundred years ago, an American produced a game. He called it indoor tennis. The Americans were not interested in it at first so he sent it to his London friends and it became very popular in Britain. The game was then played across the dining-room table or on the floor with the net hung between two chairs. In the early days ,the balls were made of cork or rubber. The bats were made of wood. A few years later a hollow ball like the one we use today was invented. The game then quickly spread all over the world. An Englishman once made a bat covered with rubber. He first played the game in England and called it "ping - pong". "Ping" was the sound of the bat when it hit the ball, and "pong" was the sound of the ball when it hit the table.

Movie Extras Would you mind lying in a coffin ? Would you shave your head? Are you willing to take out your false teeth? These are just a few of the questions Anne Marie Stewart and her staff sometimes ask the "talent" who serve as non-speaking "extras" in special films, television series, and made-for-TV movies produced in Toronto. Of course, the majority of extra calls are for more ordinary people, and Stewart has a list of about 650 registered extras. Crowd scenes, which are common, call for everyday people of all ages, ethnic backgrounds, and sizes. Over at Movie People, last-minute requests are not unusual. "We got a request once for an entire brass band of 30 people. They wanted it within the hour," said manager Yvonne McCartney. Another time, the company got a last-minute request for a newborn baby. "We found a baby that was three weeks premature," said Jonathan Aiken, an owner of the company. Then there was the worried call from a casting director whose "Star" got doggone stubborn one day and decided to just lie down and not work. The director needed a replacement dog, fast. "We got them two in one hour." said Aiken. "It was a matter of good connections and fast phone work." The eight phone lines needed to make 350 to 400 calls a day are one of Movie People's major expenses. Phone lines are the only way to stay in touch with casting directors and extras; but the latter are a group not necessarily interested in a long-term relationship. Most extra jobs pay only $7 an hour (with a six-hour minimum), while most agencies charge an annual $75 registration fee and get 10 to 15 per cent of extras' earnings. It's no wonder that the _ rate is fairly high. Some people who are between jobs do extra work as a temporary measure, said McCartney. But professionals, such as lawyers, also do the work because it's interesting. Others with flexible jobs have a desire to do something different. Some homemakers want to get out of the house and onto a movie set. Money's not the motivating reason. "One of the first things I say to people who walk in and ask about being an extra is, 'You have to be available,' "said a person at Karen Clifton Agency. Inc. "The next thing I say is, 'You can't make a living at this.' " Why do white collar workers most probably like to be movie extras?

A. They want to make more money.
B. They want to start a career in acting.
C. They think their regular job is boring.

mmlu | Question:
There is one foreign product the Japanese are buying faster than others and its popularity has caused an uneasy feeling among many Japanese. That product is foreign words. that come from outside - have been part of the Japanese language for centuries. Mostly borrowed from English and Chinese, these terms are often changed into forms no longer understood by native speakers. But in the last few years the trickle of foreign words has become a flood, and people fear the increasing use of foreign words is making it hard for the Japanese to understand each other and could lead to many people forgetting the good qualities of traditional Japanese. "The popularity of foreign words is part of the Japanese interest in anything new,"says University Lecturer and Writer Takashi Saito."By using a foreign word you can make a subject seem new, which makes it easier for the media to pick up." "Experts often study abroad and use English terms when they speak with people in their own fields. Those terms are then included in government white papers," said Muturo Kai, president of the National Language Research Institute."Foreign words find their way easily into announcements made to the general public, when they should really be explained in Japanese." Against the flow of new words, many Japanese are turning back to the study of their own language. Saito's is one of many language books that are now flying off booksellers' shelves. "We were expecting to sell the books to young people," said the writer, "but it turns out they are more popular with the older generation, who seem uneasy about the future of Japanese." What advantages do foreign words have over traditional Japanese terms?
Choices:
A. The ideas expressed in foreign words sound new.
B. Foreign words are best suited for announcements.
C. Foreign words make new subjects easier to understand.
D. The use of foreign words makes the media more popular. | A |
mmlu | Question:
Susan Sontag (1933 ------ 2004) was one of the most noticeable figures in the world of literature. For more than 40 years she made it morally necessary to know everything----- to read every book worth reading, to see every movie worth seeing. When she was still in her early 30s, publishing essays in such important magazines as Partisan Review, she appeared as the symbol of American culture life, trying hard to follow every new development in literature, film and art. With great effort and serious judgment, Sontag walked at the latest edges of world culture. Seriousness was one of Sontag's lifelong watchwords , but at a time when the barriers between the well-educated and the poorly-educated were obvious, she argued for a true openness to the pleasure of pop culture. In Notes Camp, the 1964 essay that first made her name, she explained what was then a little-known set of difficult understandings, through which she could not have been more famous. Notes on Camp, she wrote, represents "a victory of 'form' over 'content', 'beauty' over 'morals'". By conviction she was a sensualist , but by nature she was a moralist, and in the works she published in the 1970s and 1980s, it was the latter side of her that came forward. In Illness as Metaphor ------published in 1978, after she suffered cancer ------ she argued against the idea that cancer was somehow a special problem of repressed personalities, a concept that effectively blamed the victim for the disease. In fact, re-examining old positions was her lifelong habit. In America, her story of a 19thcentury Polish actress who set up a perfect society in California, won the National Book Award in 2000. But it was as a tireless, all-purpose cultural view that she made her lasting fame. "Sometimes," she once said, "I feel that, in the end, all I am really defending... is the idea of seriousness, of true seriousness." And in the end, she made us take it seriously too. According to the passage, Susan Sontag would agree to the ideas except _ .
Choices:
A. We should try hard to follow every new development in literature, film and art.
B. Cancer can be defeated because it is a special problem of repressed personalities.
C. 'Form' should be over 'content', 'beauty' should be over 'morals.
D. We should defend the idea of seriousness, of true seriousness. | B |

Lines around the eyes mean the aging process in the body. Though aging is considered as one of the most unavoidable occurrence in one's life, it is not entirely the thing. You just need to know that you can deal with it in your life. For example, if you are willing to spend a considerable amount of money to make yourself look young again, then you can try eye lifts. However, if you are more of the money-conscious type, then you should decide to go for eye creams which bring the same results but with lower prices. Despite of the advantages of using eye creams, however, there is a disadvantage in trying them. This is due to the hundreds of brands o eye creams being marketed at present.

Some of my friends are making big decisions in their life: Which universities should they apply to? I also notice that many high school students in China are thinking of studying at universities abroad. Unluckily, from what I've seen, the information given by some websites and other media about studying abroad is very limited and sometimes even wrong. There was once a Chinese girl who hoped that she could go to Columbia University in the US because she wanted to major in journalism. However, they have no journalism program at the undergraduate level! What's more, in both Canada and the US, it's not suggested that students throw themselves into journalism right after high school. School say that students should take in more knowledge about the world and writing before entering that field. The University of Waterloo, a Canadian university famous for its engineering program, is another example. The emphasis of engineering in this school may go beyond your expectations. According to our teachers, this university spent millions of dollars building a library just for engineering students. The school's computer science, mathematics and accounting are also great programs for students. But, to be honest, according to my friends who have visited this university, the campus and the food are not very nice. Maybe this is because the school stresses its academic( )strengths too much, thereby paying little attention to personal comforts. Now you see, choosing a university is really not that easy. We need to do good research and consult as many people as possible before making a decision. What's the best title for the passage?

In the next five years, STEM (science, technology, engineering and mathematics) jobs are projected to grow twice as quickly as jobs in all other fields according to the U.S. Bureau of Statistics. While all jobs are expected to grow by 10.4 percent, STEM jobs are expected to increase by 21.4 percent. By this measure, future STEM jobs represent a huge opportunity to today's students. But, in fact, of the 3.8 million ninth graders in the U.S., only 233,000 end up choosing a STEM degree in college, according to the National Center for Education Statistics. This means only 6 percent of ninth graders will become STEM graduates. And of these graduates, women will be even more underrepresented in most STEM fields. These are alarming statistics. How do we get more young boys and girls to be interested in STEM-related fields? It isn't an easy task. Schools do not always adequately prepare students for these severe subjects, and college programs are designed to get rid of those who are less persistent. Nationally, only 41 percent of initial STEM majors who begin a degree in STEM-related fields complete their degree in less than six years. In addition, social pressures continue to cast a shadow over girls who might otherwise consider the STEM fields. A couple of years ago, I met amazing parents, both of whom had a background in engineering and hoped their 10-year-old daughter would follow in their footsteps. They encouraged her to take an after-school science / robotics program. When she got there, she found she was outnumbered 6:1 by boys in the class. As the only girl, she came home crying much of the time because she was teased and told that geeky girls are not welcome in the boys' club. Ironically, by the time young boys are entering college programs in STEM fields, many complain about the lack of girls. Starting at an early age, even as young as kindergarten, we need to encourage and help the next generation leaders to consider taking up science, computing, math and technology. We also need to realize that for young girls to be inspired to take and stick with this educational path and later career field, they will benefit from the support of the people that surround them: parents, teachers, friends and family members. The STEM statistics are used in the passage mainly to show that _ .

Two days later, Mary and her little sister were searching the snow banks. "Finders are keepers" was my first thought. I didn't want to hand them out even though Susy was already crying.

Steve knew he'd been adopted as a baby, and when he turned 18, in 2003, he decided he'd try to track down his birth mother. The agency from which he'd been adopted gave him his mother's name: Tallady. But online searches didn't turn up any results about it, and Steve had to let it go. In 2007, though, he searched for the name again online. This time, the search results included a home address near the Lowe's store where Steve, then 22, worked as a deliveryman. When he mentioned the coincidence to his boss, his boss said, "You mean Tallady, who works here?" Steve and Tallady, a cashier, had said hello to each other a few times at the store, but they'd never really talked. He hadn't even known her name. Steve thought there was no possible way she was his mother though they shared the same name. For a few months, Steve avoided Tallady. "I wasn't sure how to approach her," he told a local reporter. Finally, the agency volunteered to arrange their reunion. When Tallady realized that the nice guy she'd been waving at was his son, she sobbed. She'd always hoped to meet her birth son one day. Later that day, mother and son talked for almost three hours at a nearby bar. She'd given him up for adoption in 1985, when she was 23. "I wasn't ready to be a mother," she told him.

At the age of 16, Clara Barton was advised to become a teacher, since she was quite shy. She taught in Massachusetts for ten years, and was invited to Bordentown, New Jersey, to teach in a private school. She saw personally that these communities needed free education for their citizens, and she responded by creating a free school, one of the first in her state. Later, officials ignored her and appointed a male as principal instead. She resigned and moved to Washington DC, becoming the first woman employed by the U. S. Patent Office. Clara Barton was forever changed by her experience with the troops in the Civil War. She saw surgeons dressing wounds with cornhusks , since they had nothing else. The medical supplies for the Army were well behind the troops, who were moving faster than their medical supply lines. She brought in a wagon of bandages and medical supplies that she had collected personally beforehand. Barton continued to work on the battlefields throughout the war. She helped in the identification process of 13,000 dead Union soldiers. Afterward, she was an important figure in a campaign to identify missing soldiers from the Civil War. This non-stop work _ her, and upon recommendation by her physicians, she traveled to Europe to recover herself. While in Europe, and still in poor health Miss Barton was moved by the hardship on civilians brought about by the France-Prussia war. She helped in their relief effort, and in that work she was inspired to create the Red Cross, which served all troops and civilians. Clara Barton returned to America and then began the establishment of the American Red Cross. The US government did not think there would ever be another war, after the horror of the Civil War. But she convinced them that the Red Cross would be valuable to serve in times of natural disasters, as well. This was her lasting legacy , an agency that still provides aid to victims today. What is the greatest contribution made by Clara Barton?
Choices:
A. She set up a free school.
B. She collected supplies for the army.
C. She identified missing soldiers.
D. She set up the American Red Cross. | D |

mmlu | Question:
How men first learned to invent words is unknown, in other words, the origin of language is a mystery. All we really know is that men, unlike animals, somehow invented certain sounds to express thoughts and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters, which could be combined to represent those sounds and which could be written down. Those sounds, whether spoken, or written in letters, we call words. The power of words, then, lies in their association--the thing they bring up before our minds. Words become filled with meaning for us by experience; and the longer we live, the more certain words recall to us the glad and the sad events of our past; and the more we read and learn, the more the number of words that mean something to us increase. Great writers are those who not only have great thoughts but also express these thoughts in words which appeal powerfully to our minds and emotions. This charming and telling use of words is what we call literary style. Above all, the real poet is a master of words. He can _ his meaning in words which sing like music and which by their position and association can move men to tears. We should, therefore, learn to choose our words carefully and use them accurately, or they make our speech silly and impolite. Where does the real power of the words come from?
Choices:
A. From the words themselves.
B. From their characteristics.
C. From their curiosity.
D. From their association. | D |

mmlu | Question:
Do you feel lucky? You probably don't. You may think you've got where you are today through willpower and hard work. We tend to overlook luck's role,and this seems to get worse the richer we get; surveys show that the wealthiest are least likely to owe their fortunes to good fortune. Many such people oppose taxation and government spending: why should others get a handout if they don't need one? More often than not,they vote against the very policies that helped them get lucky to begin with. In a recent Atlantic essay,Robert Frank,an economist who has studied attitudes to chance,quoted EB White: "Luck is not something you can mention in the presence of self-made men." However, if we see this just as a problem of the super-rich people,we may let the rest of us off too easily. Anyone living in a highly developed economy in 2016 is already the one who benefits from luck--for example,not living in the modern-day Central African Republic, where few people can live a long life. In fact,we are lucky to have been born human. You might have been a battery hen,or a mayfly with only one day to live. Our blindness to such truths isn't only because we're self-absorbed but also we attach more significance to things that are easier to call to mind. It's not hard to recall countless times when you put in the effort to succeed: struggling through university finals,preparing for job interviews,tolerating a long-distance travel to work. On the other hand,it's rather difficult to realize you're privileged--like not being born in a war zone,or before antibiotics ,and so forth. According to the author,you are fortunate if you are not_.

mmlu | Question:
I was born in Tuckahoe,Talbot Country,Maryland. I have no accurate knowledge of my age,never having seen any record containing it. By far the larger part of the slaves know as little of their ages as horses know of theirs,and it is the wish of most masters within my knowledge to keep their slaves thus ignorant .I do not remember having ever met a slave who could tell of his birthday. They seldom come nearer to _ than plantingtime,harvesting,springtime,or falltime. A lack of information concerning my own was a source of unhappiness to me even during childhood. The white children could tell their ages,but I could not tell. Why the same right ought to be taken away from me!I was not allowed to ask my master about it. He considered all such questions on the part of a slave improper and impolite. The nearest estimate I can live makes me now between twentyseven and twentyeight years of age. I come to this,from hearing my master say,some time during 1835,I was about seventeen years old. My mother was named Harriet Bailey. She was the daughter of Isaac and Betsey Bailey,both colored,and quite dark. My father was a white man. The opinion was also whispered that my master was my father;but of the correctness of this opinion,I know nothing and I have no means to know. My mother and I were separated when I was but an infant--before I knew her as my mother. It is a common custom,in the part of Maryland from which I ran away,to part children from their mothers at a very early age. Frequently,before the child has reached its twelfth month,its mother is taken from it,and hired out on some farm a considerable distance off,and the child is placed under the care of an older woman,too old for field labor. How does the writer feel about not knowing his age?

Bulgaria is famous for its roses and produces about 85 percent of all the rose oil in the world. Rose oil is called liquid gold and is used in making soaps, chocolates, perfumes and so on. The first records about growing roses on Bulgarian land go back many centuries. The Rose Valley developed in the area between the cities of Kazanlak and Karlovo in central Bulgaria. The roses seem to love the soil and weather there. The rose is the most important plant grown in Bulgaria, which could be called the country on the roses. The rose plantations in the Rose Valley are the largest in the world. Much of the population in the Rose Valley works in the rose industry. In Bulgaria, we produce rose oil, rose water and other products. Rose oil is used in high-quality perfumes produced in many countries. The main flower grown is the Kazanlak rose, which is famous around the world. The oil is prepared by distillation .

So you can understand why it is so expensive and is called liquid gold. Each year on the first weekend in June, during the harvest, there is a Festival of Rose in Kazanlak with many performances. Judges choose the Queen of Roses as part of the summer festival. After this, she honors the most skillful picker of roses in the harvest.

How can you help kids cope with stress? Proper rest and good nutrition can improve coping skills, so can good parenting. Make time for your kids each day. Whether they need to talk with you or just be in the same room with you, make yourself available. Even as kids get older, quality time is important. It's really hard for some people to come home after a tiring day of work, get down on the floor, and play with their kids or just talk to them about their day -- especially if they've had a stressful day themselves. But expressing interest in your kids shows that they' re important to you. Help your child deal with stress by talking about what may be causing it. Together, you can come up with a few solutions. For example, he should cut back on after-school activities, spending more time talking with his parents or teachers, developing an exercise plan or keeping a journal. You can also help by predicting potentially stressful situations and preparing kids for them. For example, let a child know ahead of time, but not too far ahead of time, that a doctor's appointment is coming up and talk about what will happen there. Keep in mind, though, that younger kids probably won't need too much advance preparation. Too much information can cause more stress. Remember that some level of stress is normal, Let kids know that it's OK to feel angry, scared, lonely, or anxious and that other people share those feelings, too. When kids can't or won't discuss these problems, try talking about your own concerns. This shows that you're willing to handle tough topics and are available to talk with when they're ready. If a child shows symptoms that concern you and is unwilling to talk, consult a counselor or other mental health experts. Most parents have the skills to cope with their children's stress. The time to seek professional attention is when any change in behavior continues to exist, when stress is causing serious anxiety, or when the behavior is causing significant problems in functioning at school or at home. You are advised not to talk too much about a stressful situation in advance because _ .
Choices:
A. it does no good to your kids
B. it doesn't work in practice
C. your kids may not feel stressed
D. your kids don't want to listen | A |

Can eating a chocolate bar every day really prevent age-related memory loss? No. But a new research shows that large amounts of flavones, substances found in cocoa, tea and some kinds of vegetables, may improve age-related memory failure. Dr. Scott Small is a professor of neurology at Columbia University in new York City He is the lead writer of a research paper describing the effects of cocoa flavones on brain activity His study involved 37 volunteers aged between 50 and 69. Researchers gave them a high-level flavones drink made from cocoa beans or a low-level flavones drink. For a period of three months, some subjects got 900 milligrams of flavones a day. The others got 10 milligrams of flavones each day. Brain imaging and memory tests were given to each study subject before and after the study Dr. Small says that the subjects who had the high-level flavones drink showed much improvement on memorytests. The researchers warn that more work is needed to be done because this study was performed only on a small group. Dr. Joann Manson is the lead researcher of a four .year study involving 18,000 adults. This study will use flavones capsules The study subjects will be divided into two groups and will take two pills per day. The capsules used will all Look the same. But one group's capsules will contain flavones, while the other group will take capsules made of an inactive substance, or placebo Dr. Manson says it's not necessary for people to start eating more chocolate, because 3 person would have to eat a huge amount of chocolate to get the same level of flavones given to the Lest subjects. He adds many manufacturers have planned to remove the flavones from their chocolate products. Similarity, Dr. says a cocoa-based flavones extract may be developed in the future But he says that more studies are needed to see how much flavones is good for our health Why will Dr. Manson carry out the four-year study?

A. To prove the first experiment is wrong
B. To carry out the experiment further
C. To test how much flavones can improve our memory.

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. What is the main idea of the passage?
Choices:
A. Animals' behaviors are researched to be applied to the study of military robots.
B. Robots, fooling tricks are applied to the study of animals'behaviors.
C. Birds and squirrels are the animals that are good at deception.

In England,factory holidays come mostly in the period between mid-July and mid-August. State schools usually only have six weeks off, from about mid-July to the end of August.

Some boardinghouse keepers give all meals to their guests, others provide breakfast only. The British may refuse to change the times at which they take their holidays, but they have shown themselves very ready to go to new places. Every year, more Englishmen, women and children go to some parts of Europe. Many take their cars, crossing the channel by ship.

mmlu | Question:
Emotional eating is when people use food as a way to deal with feelings instead of to satisfy hunger. We've all been there, finishing a whole bag of chips out of boredom or eating cookie after cookie while _ for a big test. But when done a lot -- especially without realizing it -- emotional eating can affect weight, health, and overall well-being. Not many of us make the connection between eating and our feelings. But understanding what drives emotional eating can help people take steps to change it. One of the biggest myths about emotional eating is that it's prompted by negative feelings. Yes, people often turn to food when they're stressed out, lonely, sad, anxious, or bored. But emotional eating can be linked to positive feelings too, like the romance of sharing dessert on Valentine's Day or the celebration of a holiday feast. Sometimes emotional eating is tied to major life events, like a death or a divorce. More often, though, it's the countless little daily stresses that cause someone to seek comfort or distraction in food. Emotional eating patterns can be learned: A child who is given candy after a big achievement may grow up using candy as a reward for a job well done. A kid who is given cookies as a way to stop crying may learn to link cookies with comfort. We're all emotional eaters to some extent. But for some people, emotional eating can be a real problem, causing serious weight gain or cycles of binging and purging. The trouble with emotional eating (apart from the health issues) is that once the pleasure of eating is gone, the feelings that cause it remain. And you often may feel worse about eating the amount or type of food you did. That's why it helps to know the differences between physical hunger and emotional hunger. Next time you reach for a snack, check in and see which type of hunger is driving it. The passage is mainly about _ .
Choices:
A. what emotional eating is and its harm
B. the differences between physical hunger and emotional hunger
C. how to have a healthy diet
D. the relationship between eating and feelings | A |

mmlu | Question:
Reading to oneself is modern activity which was almost unknown to the learned in the early days of the history, while during the fifteenth century the term "reading" undoubtedly meant reading aloud. Only during the nineteenth century did silent reading become popular. One should be careful, however, of supposing that silent reading came about simply because reading aloud is distraction to others. Examination of reasons connected with the historical development of silent reading shows that it became the usual mode of reading for most adult reading tasks mainly because the tasks themselves changed in character. The last century saw a gradual increase in literacy and thus in the number of readers. As readers increased, so the number of listeners dropped, and thus there was some reduction in the need to read aloud. As reading for the benefit of listeners grew less common, so came the popularity of reading as a private activity in such public places as libraries, trains and offices, where reading aloud would disturb other readers in a way. Towards the end of the century there was still heated argument over whether books should be used for information or treated respectfully, and over whether the reading of material such as newspapers was in some way mentally weakening. Indeed this argument remains with us still in education. However, whatever its advantages, the old shared literacy culture had gone and was replaced by the printed mass media on the one hand and by books and magazines for a specialized readership on the other. By the end of the century students were being advised to have some new ideas of books and to use skill in reading them which were not proper, if not impossible, for the oral reader. The social, cultural, and technological developments in the century had greatly changed what the term "reading" referred to. Educations are still arguing about _ .
Choices:
A. the amount of information provided by books and newspapers
B. the importance of silent reading
C. the value of different types of reading material
D. the effects of reading on health | C |

With everything in order, the pastor was ready to leave when the young woman suddenly remembered something very important to her. "What's that?" asked the pastor. "I want to be buried with a fork in my right hand." The pastor stood looking at the young woman, not knowing what to say. "That surprises you, doesn't it?" the young woman asked. "Well, to be honest, I'm puzzled by the request," said the pastor. The young woman explained, "In all my years of going to church meetings and dinners, I remember that when the dishes of the main course were being cleared, someone would always lean over and say, 'Keep your fork.' It was my favorite part because I knew that something better was coming, like chocolate cake or apple pie,some dessert like that. Something wonderful! I just want people to see me there in that casket with a fork so that when they ask you why I have a fork, you can tell them: 'Keep your fork--the best is yet to come.'" The pastor hugged the young woman good-bye. He knew that the young woman had a better grasp of heaven than he did. She had a better grasp of what heaven would be like than many people twice her age, with twice as much experience and knowledge. At the funeral people were walking by the young woman's casket and they saw the pretty dress she was wearing and the fork placed in her right hand. Over and over, the pastor heard the question "Why does she have a fork?" And over and over again he smiled. So the next time you reach down for your fork, let it reminded you of this young woman gently.
