mmlu | Question:
In the old days, children were familiar with birth and death as part of life. Now this is perhaps the first generation of American youngsters who have never been close by during of the birth a baby and have never experienced the death of a family member. Nowadays when people grow old, we often send them to nursing homes. When they get sick, we send them to a hospital, where children are forbidden to visit terminally in patients-- even when those patients are their parents. This deprives the dying patient of family members during the last few days of his life and it deprives the children of an experience of death, which is an important learning experience. Some of my colleagues and I once interviewed and followed about 500 terminally in order to find out what they could teach us and how we could be of more benefit, not just to them but to the members of their families as well. We were most impressed by the fact that even those patients who were not told of their serious illness were quite aware of its potential outcome. It is important for family members, and doctors and nurses to understand these patients' communication in order to truly understand their needs, fears and fantasies . Most of our patients welcomed another human being with whom they could talk openly, honestly, and frankly about their trouble. Many of them shared with us their great need to be informed, to be kept up - to - date on their medical condition and to be told when the end was near. We found out that patients who had been dealt with openly and frankly were better able to cope with the coming of detach and finally to reach a true stage of acceptance before death. The need of a dying patient for people to accompany him shows _ .
Choices:
A. his wish for communication with other people
B. his fear of death
C. his unwillingness to die
D. he feels very upset about his condition | A |

mmlu | Question:
American cities are similar to other cities around the world.In every country, cities reflect the values of the culture.American cities are changing,just as American society is changing. After World War II,the population of most large American cities decreased;however, the population in many Sun Belt cities increased.In the late 1940s and early 1950s,city residents became wealthier.They had more children so they needed more space.They moved out of their apartments in the city to buy their own homes.They bought houses in the suburbs . Now things are changing,the children of the people who left the cities in the 1950s are now adults.Many, unlike their parents,want to live in the cities.They continue to move to Sun Belt cities and older ones of the Northeast and Midwest.Many young professionals are moving back into the city.They prefer the city to the suburbs because their jobs are there;or they just enjoy the excitement and possibilities that the city offers. This population shift is bringing problems as well as benefits.Countless poor people must leave their apartments in the city because the owners want to sell the buildings or make apartments for sale instead of for rent.In the 1950s,many poor people did not have enough money to move to the suburbs;now many of these same people do not have enough money to stay in the cities. Only a few years ago,people thought that the older American cities were dying.Some city residents now see a bright,new future.Others see only problems and conflicts.One thing is sure:many dying cities in America are alive again. Why did American city residents want to live in the suburbs after World War II?
Choices:
A. Because older American cities were dying.
B. Because they were richer and needed more space.
C. Because cities contained the worst parts of society.
D. Because they could hardly afford to live in the city. | B |

mmlu | Question:
7 ways a government shutdown will affect your daily life (CNN) -- Democrats and Republicans were unable to resolve their differences over Obamacare and now the government is shut down. The two previous shutdowns -- 1995 and early 1996 -- cost the country $1.4 billion. But what will the shutdown mean for you? Here are 7 ways the government shutdown will affect you. 7. Vacation all I ever wanted: Need to get away? Well, you can't. At least not to national parks. Or to national zoos. Or to national museums. They'll be closed. Were you thinking more along the lines of a trip to France? If you don't already have a passport, you might not get your blue book in time. The last time the government shut down, 200,000 applications for passports went unprocessed. 6. If you drive a car, I'll tax the street: You may be thinking, "No functioning government, no need to pay taxes." Think again. The Man would continue to collect taxes. U.S. bonds would still be issued. And other essential banking functions will go on. 5. Wait a minute, Mr. Postman: You know that whole "Neither snow, nor rain, nor heat, nor gloom of night" thing? Apparently, the U.S. Postal Service works through shutdowns as well. Sorry, you won't catch a break from the junk mail. 4. I want a new drug: Oh, the irony . Republicans still want to _ delay or otherwise withdraw gradually at Obamacare in exchange for funding the government. But the health care act at the center of this storm would continue its process during a shutdown. That is because its funds aren't dependent on the congressional budget process. 3. Pass the ammunition : Not so fast. A shutdown would affect the Bureau of Alcohol, Tobacco, Firearms and Explosives. Translation: That gun permit you wanted processed won't happen anytime soon if this goes on for a while. 2. Money (that's what I want): Well, if you owned a small business and needed a loan from the government, you would have to wait, depending on how long this lasts. If you were planning to buy a house and needed a federal loan, you would have to wait. 1. I'm proud to be an American: Perhaps the biggest hit would be to the collective psyche . America is the largest economy in the world and a beacon for how democracy ought to work. A recent CNN Research Corporation found that 51% would blame Republicans for the shutdown. The United States has operated without a budget since 2009 and has avoided a government shutdown with last-minute deals. Not only did the government run out of money on Tuesday, but the nation is set to hit its borrowing limit and potentially default on its debt in mid-October. Together, they serve as a double whammy . According to the essay, what led to the shutdown of the American government?
Choices:
A. The government of America ran out of money.
B. The government of America is on debts.
C. America is set to hit the borrowing limit of its debts.
D. The American government ran out of money and may fail in repaying its debts. | D |
mmlu | Question:
When I was 11, 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 this as long as I could. In the end, I became so angry that I ran to my father with tears in my eyes. He listened to me quietly, then he asked. "Are the things she says true or not? Janet, didn't you ever wonder what you're 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 go to fairly clear picture of myself. I brought the list back to Dad. He refused to take it." That's 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'll 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 what you know is the right thing to do." Daddy's advice has returned to me at many important moments. In my life, I'veneverhadabetterpieceofadvice. Why did her father listen to her quietly?
Choices:
A. Because he wasn't quite sure which girl was telling the truth.
B. Because he had been so angry with his daughter's shortcomings that he wantedto show this by keeping silent for a while.
C. Because he knew that his daughter would not listen to him at that moment.
D. Because he believed that what her daughter's "enemy" said was mostly true. | D |
mmlu | Question:
CHICAGO --Bill Clinton's eagerly awaited memoir , My Life, will be published this June, and is sure to ignite a firestorm of interest in an already politically charged election year. Bill Clinton said that most presidential memoirs are thought to be "dull and self-serving, but I hope mine is interesting and self-serving." My Life, which is being published by Knopf and will sell for $ 35, is expected by many industry watchers to rise to the top of the best-seller lists. Clinton said the book tells the story of his life from his birth and childhood in Arkansas to his years in the White House. From the book readers can have a look at his successes and _ . He tells the story "as it happens to me, so you see what it's like to be president ... to see how everything happens at once." Without offering specifics or mentioning Monica Lewinsky, Clinton said, "I don't spare myself" in the book. "I have no idea if this is a great book," he said, "but it's a pretty good story. " Clinton was reportedly paid an advance of $10 million for the book, which was supposed to be done a year ago. "The minute that book goes on sale, people will be lined up buying the book," said Bob Wietrak, a vice-president and chief merchant for Barnes & Noble. Some predict the 957-page book will be one of the few presidential memoirs to fly off shelves. Booksellers have already taken pre-orders.

mmlu | Question:
The First of May is a Bank Holiday--the first public holiday of the year in England. Most people consider it a special day ,the beginning of summer ,a day when the light lasts long into the evening ,and when we can look for warm weather .We don't always get it .We feel disappointed ,but not surprised if there are cold winds and frosts at night in May .Winter should be over .Most people know that in the past ,when farming occupied almost everyone ,the changing seasons were of great importance .In that older time there was every reason to celebrate May Day .Customs of those celebrations remain. Of these customs ,the best known is the choosing of a May Queen and the dancing round Maypole .Even these customs are little more than memories now--but in the last century it was quite common in villages and small towns ,and even in schools and colleges ,for a pretty and popular girl to be chosen Queen of the May .It was a great honour to be chosen .For a day she wore a light and flowery dress, carried garlands ,and was ceremonially crowned with flowers .She presided over a procession ,as a rule with a number of attendants ,and over the Maypole dancing and all kinds of entertainment .The Maypole was slender tree trunk ,cut off its branches, with beautiful ribbons fastened to the top .The dancing was designed in such a way that the dancer's movements move the ribbons into a pattern. This, as you can imagine ,required skill from the dancer ,and was not achieved without practice . It's the Celtic people who celebrated the First of May as a spring festival .Their celebration seems to have had little to do with taking pleasure in early ,beautiful flowers and in warmer weather! They called it Beltane--the fire of the god Bel .They lit fires ,in the expectation that their blaze would help the sun in its struggle to regain its strength. They drove their cattle between banks of flame in the expectation that the terrified beasts would be purified and protected from disease .A tree ,which must have been blackened with smoke ,stood in the middle of the fires ,and is thought to have been the origin of the Maypole .Their priests made sacrifices to the goods in the hope of good harvests and sufficient store of food for the winter. There was dancing certainly ,but it was noisy and cheerful ,since its purpose was not to weave a pattern of colored ribbons ,but to drive out evil spirits from the earth and to arouse those kind spirits. According to the passage ,which sentence is NOT true?
Choices:
A. In the old days they celebrated May Day for the changing of the seasons.
B. In England summer begins at the first of May.
C. The custom of the choosing of a May Queen still exists in the present May Day celebration.
D. The Celtic people celebrated the first of May as a spring festival. | C |
mmlu | Question:
Koala bears as pets might be appealing to many of us. However, there are quite a few points to consider even before thinking of adopting one. Koala bears are one of the most lovely Australian animals. In certain cases where the koala has been raised by hand, they have turned out to be quite affectionate pets. These people tied a piece of fur to a pillow and placed it beside a joey (a baby kola) as a substitute for the mother koala. This trick seemed to work well with the baby koala. However, it is a known fact that human handling causes stress to koalas. In my personal opinion, this aspect clouds the fact that koala bears can be tamed . In Australia the koala is a priority animal as far as conservation status assessment is concerned. It was hunted to near extinction for its fur. In fact the koala had been wiped out from South Australia in the 1920s. However, rehabilitation efforts have brought the animal back in the state. As for the Australia government, the koala is not a threatened animal, but the US government does list the koala as one. Although they may live in 40 to 60 kinds of eucalyptus trees, they prefer only 10 to 14 specific kinds. Koalas sleep for most part of the day, which is about 16 to 18 hours, and for most of their waking hours all they do is eat. Koala bears eat the leaves of eucalyptus trees. A full-grown koala can eat almost 2 to 3 pounds of leaves in a day. Despite their slow movements and sweet look, koala bears can be _ when hungry. Other than this, there are the stress caused to koalas due to human handling and the fights that start in koalas. Almost everyone finds koalas lovely in the zoo. However, as far as having koala bears as pets is concerned, there are legal issues to consider. Other than that, being able to provide for its diet and habitat is another point that needs some attention before any law legalizing their adoption as pets is passed. What's the author's attitude towards people raising the koala?
Choices:
A. Optimistic.
B. Grateful.
C. Cautious.
D. Enthusiastic. | C |
mmlu | Question:
I am an English dictionary. I can still remember the day my ex-owner bought me. He had stood in front of the shelf for around half an hour before finally picking me. Originally, he chose my neighbor. But because she had some ink on the cover, he put her down and chose me instead. I may sound arrogant . But please forgive me. I am so proud of my vocabulary. With 100,000 entries and 300,000 examples, I think no scholar can be more knowledgeable than me. My only weakness is that I can't speak. But that is not my fault. I was not designed to speak in the first place. My ex-owner was supposed to read the phonetic symbols clearly printed beside each word, which were also my selling point. I should have been respected but have ended up lying next to a piece of used toilet paper inside the rubbish bin. It is all because of the electronic dictionary. He is the bad guy because he takes advantage of my one weakness. And I just don't understand why he can be so slim. He also has about 100,000entries but 450,000 examples! But I know this was not the reason why my ex-owner was attracted, for he was not a very diligent student and seldom read the examples listed. The main reason was that the bad guy had so many games in him. My ex-owner always pretended to be working hard while actually he was playing games. My ex-owner put me on his bookshelf because of my awesome English name "Advanced English Dictionary". He wanted people to think that he was an advanced learner. I wanted to tell him that it would be better if he hid the comic books standing next to me. But, you know, I can't speak. I stood there for years. I was so bored. So I talked to the comic book next to me. Under normal circumstances, I wouldn't have talked to him because I was educated and he was not. But who else could I choose? He told me that my ex-owner had read him once only and then put him there. I was upset because he had never read me from page one to page 1,000. Was I not a better book than the comic book? I wanted to challenge his honesty but before I did so, he was thrown away. I give up. My pages are absorbing waste water. There is no way people will use me again. Suddenly, I want to talk to the comic book. Would he talk to me if we met? The dictionary thinks that its ex-owner put it on the bookshelf because he _ .
Choices:
A. thought that it could match the comic books
B. wanted his friends to study English
C. just wanted to show off
D. had to use it sometimes | C |

Is your TV connected to the Internet? What about your chair,or your fridge? Probably they are not. But in the future, most things in your home may be connected, thanks to the so-called "Internet of things". The Internet of things may be coming sooner than you think. Earlier this year, A Samsung CEO spent a lot of time talking about the Internet things. He said that five years from now,every Samsung product will be part of the Internet of things,no matter whether it's a remote control or a washing machine. So, how do household objects that are part of the Internet of things work? Well,think of a common chair. When connected to the Internet, the chair warms up when it knows the user has just walked into the room and is feeling cold. An Internet-connected camera could help people feel safer in their homes. It can know people's faces and has an infrared sensor ,so even if it's dark it can see when someone passes by and send you a message on your smartphone to let you know who's there. If the person is someone you don't know,it can tell you that ,too. But according to MIT Technology Roview, whether companies are connecting dog food bowls or security systems to the Internet, there may be some problems. For example, many early connected-home objects don't have much built-in security, which means they could be hacked . Morever, it could be difficult to get these new machines to work together especially when they are made by different companies. To fight this ,many companies have joined the Open Interconnect Consortium, which had 45 menbers by late 2014. So, picture this: you enter your home.The temperature changes to make you feel comfortable. Your favorite music starts playing for you. Do you think that this would be a good thing? I t may happen sooner than you think. What does the article mainly talk about?
Choices:
A. Advantages of living with the Internet
B. Disadvantages of living with the Internet
C. The coming " Internet of things"
D. The imposslble " Internet of things" | C |
mmlu | Question:
A volcanic eruption in Iceland has sent ash across northern Europe. Airlines have stopped or changed the flights across the Atlantic Ocean, leaving hundreds of passengers stuck in airports. Grimsvotn is one of the largest and most active volcanoes in Europe. What makes Grimsvotn different is that it lies under a huge glacier of ice up to 12 metres thick. The hot volcano heats up the ice above it, which then forms a layer of water between glacier and the volcano, keeping it stable. As the water flows out from under the glacier, the pressure lifts. The lava from the volcano then comes up to the surface. This is exactly what is happening today. Now airlines have to make changes to their flights so as not to fly through the clouds of volcanic ash. According to KLM, one of Europe's biggest airlines, airplanes cannot go under the cloud or over it. Going through the cloud can result in ash getting stuck in the airplane's engines, causing damage to the plane. The eruption has also caused problems for animals in Iceland. The volcano left ash and sharp, glass-like rocks all over the countryside. Farmers are keeping their animals inside to stop them eating ash-covered grass or the sharp objects. What keeps Grimsvotn still?
Choices:
A. The slow flow of water..
B. The thick glacier.
C. The water pressure.
D. The low water temperature. | C |

Think on your feet. Use psychology," Andrew spoke with diffidence overwhelmed by his father's criticism. "You've been in this shop for six months and you haven't succeeded in selling a single computer. I tell you what. I'll give you one more chance. I'll give you another three more weeks. If you still can't make one sale, I'll call in your elder brother to replace you. He will also take over the shop when I retire. There.

The next minute he was out of the store with the shopping bag bugling with books. In his apartment (for he loves separately from his parents and little sister),he settled himself in his easy chair and devoured the contents of the books, one by one. His keen intelligence enabled him to focus the details that matter and pick out the ideas and techniques expounded.In a week his image underwent a transformation.

A. He's more convincing.
B. He's more hard-working.

D. He is more intelligence. | C |
mmlu | Question:
Researchers continue to show the power behind our sense of smell.Recent studies have found,among other things,that the smell of foods like pizza can cause uncontrollable anger in drivers on roads. The review explains that smell is unique in its effects on the brain.According to Conrad King,the researcher who carried out the review,"more than any other senses,the sense of smell goes through the logical part of the brain and acts on the systems concerned with feelings.This is why the smell of baking bread can destroy the best intentions of a dieter." Smell,which dictates the unbelievable complexity of food tastes,has always been the least understood of our senses.Our noses are able to detect up to 10,000distinct smells.Our ability to smell and taste this extremely large range of smells is controlled by something like 1,000genes ,which make up an amazing 3% of the human genome.Researchers Richard Axel and Linda Buck were together awarded a Nobel Prize in 2004for their ground-breaking research on the nature of this extraordinary sense.These two scientists were the first to describe the family of 1,000olfactory genes and to explain how our olfactory system works. According to one study in the research review,smelling fresh pizza or even the packaging of fast foods can be enough to make drivers feel impatient with other road users.They are then more likely to speed and experience uncontrollable anger on roads.The most reasonable explanation is that these can all make drivers feel hungry,and therefore desperate to satisfy their appetites. In contrast,the smells of peppermint and cinnamon were shown to improve concentration levels as well as reduce drivers'impatience.Similarly,the smells of lemon and coffee appeared to promote clear thinking and mental focus. However,the way genes regulate smell differs from person to person.A study by researchers in Israel has identified at least 50olfactory genes which are switched on in some people and not in others.They believe this may explain why some of us love some smells and tastes while others hate them.The Israel researchers say their study shows that nearly every human being shows a different pattern of active and inactive smell-detecting receptors. What is the passage mainly about?
Choices:
A. Logic and behaviour.
B. Smell and its influence.
C. Sense ability and food tastes.
D. Olfactory genes and its system. | B |

mmlu | Question:
Over the holidays, I took my three young children into a fancy chocolate shop to buy gifts. Halfway home, I noticed my 7-year-old son playing with a plastic noisemaker. Long story short: He had stolen the toy. I kept my cool -- even when he said, "but it was only $1.50, Mom!" --and explained why it was unacceptable to take things we didn't buy. A few hours later, I marched my son back to the store with two dollars from his piggy bank. He walked embarrassedly to the counter and told the clerk that he had taken something without paying for it, that he was sorry to break it and that he would pay for it now. I know exactly how terrible he was feeling. Returning to the scene of the crime is the same shame-causing punishment I received when I was five and stole something from a store. 1 remember my dad sending me back to return the item. It remains one of my clearest child- hood memories. After that day, I never stole again. My dad taught me such an important lesson 30 years ago and I saw an opportunity to do the same for my son. But now I wonder if it was the fight thing to do. "Returning to the store is absolutely the right thing to do," Laura Markham, Ph.D., a child psychologist and author of Peaceful Parent, Happy Kids, says. "Many children steal -- they' re not born knowing the rules so it' s our job to teach them." And stay calm when you set them. "If you overreact or yell, you might create a fascination with the behavior and a willful child will be more likely to fight against you," she says. Having a child physically return the stolen item helps him or her grasp the situation -- and the consequence. But don't talk about it for too long. "lf you continuously bring up the incident, the child will believe they' re a thief and that they' re bad," she says. Only time will tell if this experience will have the same powerful effect on my son as it had on me, but at the same time I can rest if I haven' t dealt with the situation badly. What does the author think of Laura Markham' s words?
Choices:
A. They are doubtful.

When Geoff Marcy was 14, his parents bought him a telescope. Every night, he would go onto the roof outside his window to see the wonders of the sky. "What excited me most was whether there were planets in other solar systems where life might exist," he says. "I decided to try to find planets orbiting other stars like our Sun." And he did. "My fellow researcher, Paul Butler, and I found our first planet in 1995," Dr. Marcy says. "We worked for ten years without finding anything! _ and our patience paid off." Since then, the two scientists have discovered 65 of the more than 100 planets found orbiting other stars. Dr. Marcy and Dr. Butler also spotted the first "family" of three planets. In June 2002 they announced another discovery: a Jupiter-like planet orbiting star 55Cancri. At first, the two researchers found only planets that orbit close to stars. Recently, the scientists found planets farther out. The planet orbiting 55Cancri is a major breakthrough: it is the first sighting of a large gas planet about same distance from the star as Jupiter is from the Sun. Why is this important ? Scientists think that life on Earth may exist because of two special features in our solar system. The first is Jupiter. "Because it's so big, Jupiter pulls comets and asteroids , or they all come and hit the Earth." Dr. Marcy explains. "Without Jupiter , life on Earth would likely have been destroyed." A second feature is that Earth is a rocky planet where liquid water, which is necessary for life , can exist. Unlike gas planets, rocky planets like Earth have surfaces where water can gather in pools and seas, which may support life. A huge space exists between the Jupiter-like planet and two other planets that lie close to 55Cancri. Is there an Earth-like planet in the space, too small for us to notice? If so, says Dr. Marcy, "We would have two striking similarities to our solar system: a Jupiter-like planet and an Earth-like planet. And there may be life!" What can we learn about Dr. Marcy from the passage?
Choices:
A. He is fond of watching Jupiter.
B. He is from a scientist family.
C. He dislikes working with Paul Butler.
D. He is interested in finding life in outer space. | D |

Taste is such a subjective matter that we don't usually conduct preference tests for food. The most you can say about anyone's preference is that it's one person's opinion. But because the two big cola companies--Coca-Cola and Pepsi Cola are marketed so aggressively, we've wondered how big a role taste preference actually plays in brand loyalty. We set up a taste test that challenged people who identified themselves as either Coca-Cola or Pepsi fans: Find your brand in a blind tasting. We invited staff volunteers who had a strong liking for either Coca-Cola Classic or Pepsi, Diet Coke, or Diet Pepsi. These were people who thought they'd have no trouble telling their brand from the other brand. We eventually located 19 regular cola drinkers and 27 diet cola drinkers. Then we fed them four unidentified samples of cola one at a time, regular colas for the one group, diet versions for the other. We asked them to tell us whether each sample was Coke or Pepsi; then we analyzed the records statistically to compare the participants' choices with what mere guess-work could have accomplished. Getting all four samples right was a tough test, but not too tough, we thought, for people who believed they could recognize their brand. In the end, only 7 out of 19 regular cola drinkers correctly identified their brand of choice in all four trials. The diet-cola drinkers did a little worse----only 7 of 27 identified all four samples correctly. While both groups did better than chance would predict, nearly half the participants in each group made the wrong choice two or more times. Two people got all four samples wrong. Overall, half the participants did about as well on the last round of tasting as on the first, so tiredness, or taste _ , was not a factor. Our preference test results suggest that only a few Pepsi participants and Coke fans may really be able to tell their favorite brand by taste and price. The author's purpose in writing this passage is to _ .
Choices:
A. emphasize that taste and price are closely related to each other
B. recommend that blind tasting be introduced in the quality control of colas
C. show that taste preference is highly subjective
D. argue that taste testing is an important marketing strategy | C |

mmlu | Question:
DJs(disc jockeys) are the people who play and present music on the radio, or in nightclub. A VJ(video jockey) is a person who introduces music videos on television. VJs were first seen on television in the early 1980s when MTV went on the air. As MTV became popular, and the audience for music videos expanded, a variety of other music video channels started broadcasting. In addition to rock music, there were channels for people who had a lot of interest in alternative kinds of music, such as country music, light music, and R&B(rhythm and blues), and all of these channels needed VJs. By the 1990s, international music video channels like Channel V in Asia and VIVA in Europe had started. The VJs for the new international stations had to be chosen carefully. Although some VJs did shows that focused on small audiences and showed mostly local content, other VJs presented shows for international viewers. These VJs, and the material they presented, needed to be popular in several different cultures. One successful international VJ in Asia is Asha Gill. She is from prefix = st1 /Malaysia, but her parents and grandparents are fromIndia,FranceandEngland. She speaks three languages and has fans across Asia, fromJapanto theUnited Arab Emirates. Another VJ who has made a big hit in Asia is Lili. She is actually a computer- Animated VJ on MTV Asia. An actress wearing special computer equipment makes Lili move like a puppet . The actress also talks for Lili, and her shows can be seen in five languages. When asked what makes a good video jockey, many successful VJs have given similar answers. To be a good VJ you need to know a lot about music, you need to be funny, and you can't be shy. What do Channel V and VIVA have in common?
Choices:
A. They are both owned by MTV
B. They are music video channels in Asia
C. They have viewers in more than one country

Mr. Harris used to work in Dover, but then he changed his work, and he and his wife moved to another town. They did not have many friends there, but they soon met a lot of interesting people, and after a few weeks, they often went to dinner or to parties at other people's houses. Then Mrs. Harris said to her husband, "We've been to a lot of other people's houses, and now we must invite them to our house, mustn't we?" "Yes, certainly," answered her husband, "A big party will be the easiest thing, won't it? Then we can start to invite people to dinner in small numbers next month." So Mrs. Harris said, "Yes, I'll invite all our friends here to a big party on 5th December." "How many will that be?" Mr. Harris asked. "Don't invite too many." Mrs. Harris was beginning to write the invitations when her husband saw that she was writing, "Party. 6.30 to 8.30 p.m." "That isn't very nice, is it?" he said. "You're telling our guests that they must go at 8.30." So Mrs. Harris just wrote "Party. 6.30 p.m." A lot of guests came, and they all had a good time, so they did not go home at 8.30. In fact they were still there at mid-night when the door bell rang and a policeman arrived. He said, "You must stop making a noise, because someone has complained." Mr. Harris said he did not want to quarrel with the policeman, so everyone went home. They were sorry to have to go. When Mr. and Mrs. Harris were alone again, she said to him.

When I was small and my grandmother died, I couldn't understand why I had no tears. But that night when my dad tried to cheer me up, my laugh turned into crying. So it came as no surprise to learn that researchers believe crying and laughing come from the same part of the brain. Just as laughing has many health advantages, scientists are discovering that so, too, does crying. Whatever it takes for us to reduce pressure is important to our emotional health, and a study found that 85 percent of women and 73 percent of men report feeling better after crying. Besides, tears attract help from other people. Researchers agree that when we cry, people around us become kinder and friendly and they are more ready to provide support and comfort. Tears also enable us to understand our emotions better; sometimes we don't even know we' re very sad until we cry. We learn about our emotions through crying, and then we can deal with them. Just as crying can be healthy, not crying -- holding back tears of anger, pain or suffering -- can be bad for physical health, Studies have shown that too much control of emotions can lead to high blood pressure, heart problems and some other illnesses. If you have a health problem, doctors will certainly not ask you to cry. But when you feel like crying, don't fight it. It's a natural -- and healthy -- emotional response . According to the author, which of the following statements is TRUE?
Choices:
A. Crying is the best way to get help from others.
B. Fighting back tears may cause some health problems.
C. We will never know our deep feelings unless we cry.

Lin Xiao, 21, a student at Guangdong University, has a big family - her two parents, a younger brother and two younger sisters. Lin took her role as the "big sister" seriously. When her first sister was born, Lin took turns with her mom holding the baby late into the night. "I almost did everything that was supposed to be a parent's job, but I felt proud of myself," she said. Not all of Lin's classmates shared her experiences because of the family planning policy , a law that was carried out in China about forty years ago. But the situation is about to change. A new policy made on October 29 said all couples can now have two children. The new policy is expected to help raise the population of China. Recently, China has been facing an aging population and labor shortages because of the low birth rate . The two-child policy may also be the gift for every only child. Researchers found that growing up with a brother or sister can have good influence on one's mental health. "Brothers and sisters do matter in unique ways. They give kids something that parents don't." Laura Walker, a professor from Beijing University, told China Daily. She noted that having a brother or a sister protects teenagers against loneliness, fear and so on. Liu Fang, 20, from Shenzhen University, has a 2-year-younger sister. When her sister disagreed with parents over choosing a college major, she helped her to communicate with parents. "If necessary, I would always have her back," said Liu. "The best part of having a sister is that you have a partner, friend and supporter throughout your life." But children with brothers or sisters also have to learn to understand and look after each other, said Laura. We can infer from the article that _ .

People who have the habit of texting while walking tend to develop a robot-like posture, lose their balance, and involve themselves in traffic accidents, according to a research from the University of Queensland. Researchers said that text-walkers are in danger of walking into traffic and train tracks among others. They suggest pedestrians stop aside, type a text and then continue walking. For the study, the researchers tracked body movements of 26 young men and women while walking in a straight line over a distance of about 8.5 m ---once without a mobile phone, once while reading a text message and once while typing a message. They found that participants' body movements were greatly changed when they used their phone. The difference in their posture was more _ while sending a text than while reading a message. They further said that when those people began texting while walking, they slowed down their pace, went off course and moved their necks less than when reading a message. "We found that they 'locking' their arms, trunk and head together walked with a posture that was robot-like, all in aid of keeping their phone in their field of vision. So there is less movement between each of their body parts." Researcher Siobhan Schabrun said, Daily Mail UK reports. "In recent years, there have been many reports of people involved in traffic accidents because they were texting while walking. The number of pedestrian accidents is rising and texting has been blamed," Schabrun said. Despite such repeated accidents, only few studies have analyzed the impact of texting on body language. If more studies concentrate on walking styles adopted while texting, their findings can be used to lower whole accidents. While a few U.S. states have introduced laws on texting while driving, Fort Lee, a New Jersey town, went further ahead and recently fined some walkers an $85 for catching them texting. It is hoped that other American states and countries will follow. When texting, the pedestrians walk in a different way to _ .

A written contract was entered into between Bouquet, a financier-investor, and Vintage Corporation, a winery and grape-grower. The contract provided that Bouquet would invest $1,000,000 in Vintage for its capital expansion and, in return, that Vintage, from grapes grown in its famous vineyards, would produce and market at least 500,000 bottles of wine each year for five years under the label "Premium VintageBouquet." The contract included provisions that the parties would share equally the profits and losses from the venture and that, if feasible, the wine would be distributed by Vintage only through Claret, a wholesale distributor of fine wines. Neither Bouquet nor Vintage had previously dealt with Claret. Claret learned of the contract two days later from reading a trade newspaper. In reliance thereon, he immediately hired an additional sales executive and contracted for enlargement of his wine storage and display facility. "If Vintage refuses to distribute the wine through Claret and Claret then sues Vintage for breach of contract, is it likely that Claret will prevail?

It's easy to see how to help others, but what about those whose needs aren't so obvious? This story may have happened a while back, but it was a lesson which has stayed with me and helped me ever since. It was Thanksgiving and I was volunteering with my parents at a shelter for the poor. We stood behind the counter dishing out hot food to whoever came in. most of our dinners looked like they had been having hard times, their clothes old, worn and dry. In short, they looked poor! Then, a man came in, who looked anything but poor. He was well dressed, wearing an expensive suit. I wondered what he was doing there and my jaw dropped in amazement when he joined the line for food. The closer he came to my service station, the more I muttered. What was this man doing? I wanted to know. Surely he wasn't gong to take food. Then my mother quietly took me to one side. She said, "You have assumed that the needs of the people who come here must be purely physical: hunger, inadequate shelter and needs are emotional? What if he needs comfort, friends, or just to be among other human beings?" her words hit me like a ton of bricks! I felt like I should apologize to the man, but I didn't. About a week later the shelter received a large donation from an anonymous source. I can't help but wonder if it came from that man.

mmlu | Question:
Through history, children have played with toys and they help to prepare children for adult life. But the toys are changing all the time. As science and technology have changed the way adults live, the toys children play with have changed as well. Developments in science and technology have had a big effect on the toys that children play with. Today trains and mobile phones are popular toys for young children, but there were no toys of this kind before real trains and mobile phones were invented. The materials that toys are made of have also changed. Today lots of toys are made of plastic. Plastic is a modern, man-made material that did not exist in the past. On the other hand, some other toys that you have might not be all that different from the ones children played with 1,000 years ago. Scientists have found some bone dice in Aberdeen. In medieval times dice were used for playing games as much as they are today. A recent survey found that half of all the children aged from 4 to 6 have played video games, a quarter of them regularly. The increasing use of electronic toys troubles Dr Singer, a professor at Yale. "One thing we know is that kids in early years need to be in touch with the real world," he said, "No matter how brilliant they are, they're not going to learn to walk, to move or to talk to others unless their hands or feet have a direct role in such activities." Some toy experts argue that the best toys are the ones that increase a child's creativity and imagination. Traditional toys can be used for different kinds of purposes and be used in group settings, individually , and one-to-one. They are also used differently depending on the child's age and skill level. And these toys made of natural materials are valuable for children because they teach children what the world is made of. According to Dr Singer, _ .
Choices:
A. the electronic toys are good for children if they play often enough

Movie fans know that their action hero Superman does not really fly.And, in the movie Superman Returns, another visual trick is played on viewers.The man they see flying is not real.He is what is called a virtual actor.The first step in creating this digital actor is to have a real person stand in a room called a light stage.A computer then captures the outlines and shapes of his face and records how they throw off light .Paul Debevec is with the Institute for Creative Technologies at the University of Southern California. "We can light them with very specially computer-controlled illumination and take photos of them from seven different viewpoints with high quality digital still cameras." Mr.Debevec is part of a team working to create computerized images of people, objects and environments that look and act real.The light stage permits actors to be turned into digital versions of themselves much like the blue creatures in the movie Avatar.The real world could soon be using a similar technology.Computer experts at the Institute are developing a 3-D video teleconferencing system.It would send a video image of a person into a meeting room.That image would be able to work with the people in the room, who would see it in 3-D without special eyeglasses.Paul Debevec says: "The person who is being transmitted to a remote location can actually look around at the people in the room and everybody in that room knows who they're looking at .And that's such a fundamental part of human communication."

Chinese mainland's star-making reality TV show "Happy Boy" will not be open to male applicants from Hong Kong, prefix = st1 /Taiwan, Macau or other foreign cities, said the country's top TV industry committee yesterday. Happy Boy is the male version of Super Girl, which is regarded as the Chinese version of American Idol. The girl's event, operated by central China's Hunan TV, drew an audience of 400 million for the final match in 2005. The country's State Administration of Radio, Film and Television approved the male version earlier this month. However, the regulation that only mainland's male applicants are allowed to register was released just days before the application procedure began on Wednesday inChangsha, one of the five mainland cities to hold the contest. The other four includesChengduand three undecided cities. The regulation _ Hunan TV's ambition to extend the series to the overseas market, an official with the TV station told the Hunan-based Xiaoxiang Morning yesterday. "My Hero," another star-making reality show byShanghai's SMG Dragon TV, said it was not informed of the regulation, and it is still receiving foreign applicants, said an official with Dragon TV. A previous regulation by the administration has made clear that televised talent shows can't run for more than six weeks at a time. While the first "Happy Boy" may last for five months, according to a previous report. Last year there were about 10 influential star-making TV shows across the country, among which those from CCTV, Hunan Satellite TV and SMG's Dragon TV, were the most popular. "Super Girl" ran for almost five months and "My Hero" lasted four months. While the shows have proven popular, they have also earned many complaints from people who say they are crude and not satisfactory. We can safely draw the conclusion that _ .

As a parent you might never guess all the ways a good imagination benefits your child. It helps a preschooler : Develop social skills As children play pretend, they explore relationships between family members, friends and coworkers and learn more about how people interact. Playing doctor, they imagine how physicians care for their patients. Playing house, they learn more about how parents feel about their children. Imaginative play helps develop empathy for others. If children can imagine how it feels to be left out of a game or to lose a pet, they are better able to help those in need. They become more willing to play fair, to share, and to cooperate. Build selfconfidence Young children have very little control over their lives. Imagining oneself as a builder of skyscrapers or a superhero defending the planet is empowering to a child. It helps them develop confidence in their abilities and their potential. Boost intellectual growth Using the imagination is the beginning of abstract thought.Children who can see a king's castle in a mound of sand or a delicious dinner in a mud pie are learning to think symbolically . This skill is important in school where a child will have to learn that numerals symbolize groups of objects, letters symbolize sounds, and so on. Practice language skills Kids who play pretend with their friends do a lot of talking.This helps _ their vocabulary, improve sentence structure and promote communication skills. Work out fears Playing pretend can help children work out their fears and worries. When children roleplay about the big, bad monster under the bed, they gain a sense of control over him and he doesn't seem quite so big or so bad. Imaginative play also helps kids vent confusing feelings they might have, such as anger toward a parent or compete with a new sibling . To encourage your youngster's imagination, read to him every day. Books offer children the opportunity to visit other worlds and create new ones of their own. For generations children have enjoyed reading the story of Peter Pan because Peter takes them on fascinating adventures.Reader's Digest Young Families offers a beautiful typical Disney edition of Peter Pan, which is an iParenting Media Award winner.

Something in chocolate could be used to stop coughs and lead to more effective medicines, say UK researchers. Their study found that theobromine , found in cocoa, was nearly a third more effective in stopping coughs than codeine, which was considered the best cough medicine at present. The Imperial College London researchers who published their results online said the discovery could lead to more effective cough treatment. "While coughing is not necessarily harmful it can have a major effect on the quality of life, and this discovery could be a huge step forward in treating this problem," said Professor Peter Barnes. Ten healthy volunteers were given theobromine, codeine or placebo, a pill that contains no medicine, during the experiment. Neither the volunteers nor the researchers knew who received which pill. The researchers then measured levels of capsaicin, which is used in research to cause coughing and as a sign of how well the medicines are stopping coughs. The team found that, when the volunteers were given theobromine, the capsaicin needed to produce a cough was around a third higher than in the placebo group. When they were given codeine they needed only slightly higher levers of capsaicin to cause a cough compared with the placebo. The researchers said that theobromine worked by keeping down a nerve activity , which cause coughing. They also found that unlike some standard cough treatments, theobromine caused no side effects such as sleepiness. We learn from the text that volunteers in the experiment _ .

When I arrived, it was early morning and it was raining. I looked to the east--the sky was becoming grey. I got out of the car, went through a gate and walked along a dark path. There was nothing to see, but I knew it was there. After about a mile, a stranger appeared beside the path. "Am I going the right way?" I asked. He knew where I was going. "Yes," he replied. "you'll get there in five minutes." Finally, I came to some rocks and stopped. I looked over them, but it was silent and there was no sign of it. Suddenly, the rain stopped and the clouds cleared. The sun rose behind me and shone on the rocks. Far below me, the ground fell away and down to a river. I was looking across one of the wonders of the natural world -the Grand Canyon. I looked down to the Colorado River, a silver stream nearly one mile below me. If you put the two tallest buildings in the world on top of each other at the bottom of the canyon, they still would not reach the top. Then I looked across to the other side of the canyon. It was about fifteen miles away, maybe more. Finally, I looked to my left and to my right, and on both sides the canyon went far away for more than 200 miles. The Grand Canyon was not just big. It was huge! I remained by the canyon for about half an hour, and I asked myself, "Is the Grand Canyon the greatest wonder of the natural world?" I certainly know the answer. What do you think? Why was there nothing to see?

mmlu | Question:
My life suffered a lot in summer five years ago. My father died in a car accident,leaving my mother,my two younger brothers and I alone. At that time,I was a senior high school student. After my father's funeral,I had no choice but to drop out of school and work in a factory. I really wanted to return to school and wanted to go to college,but I couldn't. I only hoped to bring up my two young brothers. Life was not easy for me,for I can't afford their tuition even if I worked from day to night without stopping. Without my father's protection,I thought I was a slave to the fate. Later on,something changed my life. I still remember that it was a rainy day. I put myself in the rain and walked slowly in the street. Suddenly the rain stopped!I raised my head and found "the sky" was in fact a dark blue umbrella. Then I noticed a middleaged man with one leg on crutch standing behind me. He said to me,"Why not run without an umbrella?If you didn't run,you would get drenched." The man told me that he was a promoter. He once dreamed of being a policeman,but an accident ruined his dream. Though his present job was not suitable for his legs,it was a wonderful start to him. He was very happy that he didn't lose heart and still "ran" on the road of life... I was encouraged by the man's words. I went to a big city and became an assurance representative. After two years' running,I did well and my family condition turned better little by little. Later I returned to school and succeeded in my entrance to university. Life is like this. When you are in rainy days in your life,if you couldn't find a way to prevent you from being wet,you would be overwhelmed. But if you decide to get rid of it,you'll discover that the rainy days last not so long as you imagine. What's the best title of the passage?

An average 30-year-old person who has eaten three meals a day since birth has eaten more than 30,000 meals to date. Even if you've only eaten half that much, you have to admit this: you've let some of that breakfast, lunch or dinner go to waste. And it turns out that we're all to blame for this shaming fact: 30% of all food produced in the world each year is wasted or lost. That's about 1.3 billion tons, according to a new report by the U.N. Food and Agriculture Organization. That's the weight of more than 8.6 million full-grown blue whales, the largest creatures on earth. That's the weight of more than 2.3 million Airbus A380s, the largest planes in existence. That's as if each person in China, the world's most populous country with more than 1.3 billion people, had one ton mass of food they could just throw into the dustbin. It's almost _ ,isn't it? Setting aside that big number, we find the people with the most money are the ones who waste the most. Per capita( ), European and North American countries waste between 95 and 115 kilograms of food. Sub-Saharan African, South Asian and Southeast Asian countries waste much less -- between 6 and 11 kilograms per person. Here's another statistic: all the food that the world's richest countries waste is about equal to all the food that sub-Saharan Africa produces. The numbers: 222 million tons and 230 million tons, respectively( ). Basically, the wasted food of the rich could feed much of the African continent. And these numbers come as we've just been reporting about rising food prices around the world in the past week. And my own personal tip: if I eat at a restaurant and can't finish it all, I ask for a doggie bag. I used to be a waiter years ago and will never forget the amounts of food I saw left on the table after the bill was paid. There's no reason to waste food. It's up to all of us to use our common sense to eat and shop just a bit more wisely. What is the purpose of this article?
Choices:
A. To show the author's opinion of food.
B. To let us live more wisely and not waste food.
C. To show the amount of wasted food a year.
D. To ask the richest countries to help African people. | B |
mmlu | Question:
In many businesses, computers have largely replaced paperwork, because they are fast, and do not make mistakes. And they are honest. Many banks say that their business is "untouched by human hands" and therefore safe. But they have no thought that the growing number of computer crimes show they can be used to steal. Computer criminals don't use guns. And even if they are caught, it is hard to punish them because there is often no proof. A computer cannot remember who used it. It simply does what it is told. The head teller at a New York City bank used a computer to steal more than one and a half billion dollars in just four years. No one noticed this because he moved the money from one account to another. Each time a customer whose money he had stolen questioned the balance in his account, the teller said it was a computer mistake, then replaced the missing money from someone else's account. This man was caught at last. Some workers use the computer's power to punish their bosses they consider unfair. Recently, a large company fired its computer record assistant for reasons that were connected with her personal life rather than her job. She was given thirty days notice. In those thirty days, she stole all the company's computerized records. Most computer criminals have been common workers. Now police wonder if this is "the tip of iceberg". As one official says, "I have the feeling that there is more crime out there than we are catching. What we are seeing now is all so poorly done. I wonder what the real experts are doing--the ones who really know a computer works." Business in many banks is declared to be safe because _ .

Stoven, who owned Craigmont in fee simple, mortgaged Craigmont to Ulrich to secure a loan of $100,000. The mortgage was promptly and properly recorded. Stoven later mortgaged Craigmont to Martin to secure a loan of $50,000. The mortgage was promptly and properly recorded. Subsequently, Stoven conveyed Craigmont to Fritsch. About a year later, Fritsch borrowed $100,000 from Zorn, an elderly widow, and gave her a mortgage on Craigmont to secure repayment of the loan. Zorn did not know about the mortgage held by Martin. The understanding between Fritsch and Zorn was that Fritsch would use the $100,000 to pay off the mortgage held by Ulrich and that Zorn would, therefore, have a first mortgage on Craigmont. Zorn's mortgage was promptly and properly recorded. Fritsch paid the $100,000 received from Zorn to Ulrich and obtained and recorded a release of the Ulrich mortgage. The $50,000 debt secured by the Martin mortgage was not paid when it was due, and Martin brought an appropriate action to foreclose, joining Stoven, Fritsch, and Zorn as defendants and alleging that Martin's mortgage was senior to Zorn's mortgage on Craigmont. If the court rules that Zorn's mortgage is entitled to priority over Martin's mortgage, which of the following determinations are necessary to support that ruling? I. Ulrich's mortgage was originally senior to Martin's mortgage. II. Zorn is entitled to have Ulrich's mortgage revived for her benefit, and Zorn is entitled to be subrogated to Ulrich's original position as senior mortgagee. III. There are no countervailing equities in favor of Martin.

A. I and II only.

Can people change their skin color1 without suffering like pop king Michael Jackson? Perhaps yes. Scientists have found the gene that determines skin color1. The gene comes in two versions, one of which is found in 99 percent of Europeans. The other is found in 93 to 100 percent of Africans, researchers at Pennsylvania State University report in the latest issue of science. Scientists have changed the color1 of a dark-striped zebrafish to uniform gold by inserting a version of the pigment gene into a young fish. As with humans, zebrafish skin color1 is determined by pigment cells, which contain melanin . The number, size and darkness of melanin per pigment cell determine skin color1. It appears that, like the golden zebrafish, light-skinned Europeans also have a mutation in the gene for melanin production. This results in less pigmented skin. However, Keith Cheng, leader of the research team, points out that the mutation is different in human and zebrafish genes. Humans acquired dark skin in Africa about 1.5 million years ago to protect bodies from ultra-violet rays of the sun , which can cause skin cancer. But when modern humans leave Africa to live in northern latitudes, they need more sunlight on their skin to produce vitamin D. So the related gene changes, according to Cheng. "Asians have the same version of the gene as Africans, so they probably acquired their light skin through the action of some other gene that affects skin color1," said Cheng. The new discovery could lead to medical treatments for skin cancer. It also could lead to research into ways to change skin color1 without damaging it like chemical treatment did on Michael Jackson. ks5u The reason why Europeans are light-skinned is probably that _

A. they are born light-skinned people

As a professor at a large American university,there is a phrase that I hear often from students:"I'm only a 1050."The unlucky students are speaking of the score on the Scholastic Aptitude Test(SAT),which is used to determine whether they will be admitted to the college or university of their choice,or even if they have a chance to get a higher education at all.The SAT score,whether it is 800,1100 or 1550,has become the focus at this time of their life. It is obvious that if students value highly their test scores,then a great amount of their self-respect is put in the number.Students who perform poorly on the exam are left feeling that it is all over.The low test score,they think,will make it impossible for them to get into a good college.And without a degree from a _ ,they fear that many of life's doors will remain forever closed. According to a study done in the 1990s,the SAT is only a reliable indicator of a student's future performance in most cases.Interestingly,it becomes much more accurate when it is set together with other indicators-like a student's high school grades.Even if standardized tests like the SAT could show a student's academic proficiency ,they will never be able to test things like confidence,efforts and willpower,and are unable to give us the full picture of a student's potentialities .This is not to suggest that we should stop using SAT scores in our college admission process.The SAT is an excellent test in many ways,and the score is still a useful means of testing students.However,it should be only one of many methods used. Students' self-respect is influenced by their _ .

Some people like to get up early, but some do not. In fact, it is really good for us to get up early every day. Maybe those who don't like getting up early will not believe this, but it is true. Scientists made a survey in about one thousand people, and then they found that early rising people had less disease than late rising people, and early rising people also look healthier than late rising people, and so on. So we may know early rising is helpful in more than one way. First, it helps to keep us healthy. We all need fresh air. But air is never so fresh as early in the morning. Besides, it is useful to do morning exercises. Secondly, early rising helps us in our studies. In the morning we learn more quickly and find it easier to understand what we learn. Thirdly, early rising can give us a plan of our work for the day. We cannot work well without a good plan. Fourthly; early rising gives us enough time to get ready for our work, such as to wash our hands and faces and eat our breakfast. Late risers may find it difficult to form the habit of early rising. They have to make an effort to do so. As the English proverb says, "Early to bed and early to rise makes a man healthy, wealthy and wise. " If a man always likes to get up late, it's _ for him to form the habit of getting up early.

People around the world drink about 180 billion liters of soda a year. That translates to more than 29 liters per person. Experts say the amount of carbonated soft drinks we consume is growing. New research from the American Heart Association finds that drinking soda, even diet soda, may significantly increase your risk for heart disease. Dr. Ramachandran Vasan led the study. "Drinking just one or more sodas a day may not be as innocuous as people think." In a large study of 9,000 people, doctors discovered that those who drank one or more sodas a day had a 30% increased risk for obesity , a 25% increase in the risk for abnormal blood sugar levels, and a 32% increase in the odds of having low levels of good cholesterol . All of these factors increase the risk for heart disease. And there was no difference in the results for those who drank diet soda over regular soda. It's something that surprised even the researchers. Critics of the study say diet soda may not be the cause of increased risk of heart disease. Connie Diekman is president of the American Dietetic Association. "It does not conclusively say that this will cause that." In other words, it could be that unhealthy people like soda. Dr. Vasan found those who drink soda generally tend to have greater caloric intake. They eat more saturated fat and trans fats. They also eat less fiber and exercise less. Diet soda drinkers may also share this unhealthy lifestyle. Dr. Vasan agrees that the link he found between heart disease risk and diet soda needs additional study. What can be inferred from the passage above?
Choices:
A. All the experts agree with the results of the study.
B. Sodas of any kind are certain to increase the risk for heart disease.
C. People have expected the results of the research.
D. More studies are needed to prove the results. | D |

Perhaps the only test score that I remember is the 55 when I was in high school. The test was the final for a course. I remember waiting anxiously as my teacher Mr. Right passed out our papers one by one. It was a rather difficult test. I heard my classmates groaning , and I could tell by the groans that the scores weren't looking good. Mr. Right put my paper on my desk. There in big red numbers, circled to draw attention, was my score, 55! I lowered my head, and covered the score up quickly. A 55 is not something that you wanted your classmates to see. "The scores were not very good, none of you passed," Mr. Right said. "The highest score in the class was a 55." A 55. That's me! Suddenly my sad look didn't look so bad. I had the highest score. I felt a lot better. I walked home alone that day with the low but high score. My father knew that I had a big test that day and asked me as soon as I got home, "How did you do in your test?" "I made a 55," I said. A frown now stood on my father's face. I knew I had to explain immediately. "But Dad, I had the highest score in the class," I proudly stated. I thought that explanation would make a difference. "You failed!" my father replied. "But it's the highest!" I insisted. "I don't care what scores others had, but you failed. What matters is what you do!" my father firmly said. For years, my father was always that way. It didn't matter what others did, it only mattered what I did and that I did it excellently. We often don't understand the wisdom of good parents until we ourselves stand in the parents' shoes. My father's words have carried me throughout life.

One day in the Reform Club, Phileas Fogg, a wealthy gentleman, accepts a wager for PS20,000, which he will receive if he travels around the world in 80 days. Phileas Fogg sets off immediately, with his servant Passepartout. They reach Suez quickly. While landing in Egypt, he is watched by a British detective named Fix, who is in search of a bank robber. Because Fix mistakes Fogg for the criminal, he follows secretly, as they are getting on a ship to Bombay.

Since the 1990s, education has been required for all South Africans from age seven to fifteen. Last December, the government announced that 70% of students passed their final examination to finish high school. In 2008, the pass rate was about 63%. There have been increases each year since then. Professor Shireen Motala says basic education is no longer a problem in South Africa. Most children stay in school until they are about sixteen. The problem is that large numbers of them leave without completing high school. Students take an examination known as the "matric" in Grade Twelve. Professor Motala says, "Less than half of the children who started school in 2000 sat for the matric last year. Many dropped out of school, so only around 45% took the matric. And the worry is where those students actually go." Those who drop out have to compete with better educated people for jobs. Educational researchers also point to another problem. South African schools do not produce enough students with the skills for higher education in maths and science. Many schools are not well-equipped. Children do not see laboratories, and, as a result, their science marks are not very good. They do not have libraries at school. Also, many teachers do not have the skills or training to do their jobs. In South Africa, a number of teachers were poorly trained before. Secondly, teachers have been confused by the many educational reform efforts in the last fifteen years. Finally, language differences in the classroom have not got as much attention as they should, which is a huge problem. Subjects such as maths and science are taught in English starting at about the age of ten. But South Africa has eleven official languages. South Africa's minister of basic education promises a number of improvements. Angie Motshega says teacher development efforts will focus on subject and content knowledge, making sure that the correct teachers are in the correct jobs. South African students perform poorly in science for all of the following reasons, EXCEPT _ .

A. they don't work hard enough
B. their schools do not have laboratories
C. they cannot get help from libraries

Your glasses may someday replace your smartphone, and some New Yorkers are ready for the switch. Some in the city can't wait to try them on and use the maps and GPS that the futuristic eyewear is likely to include. "I'd use it if I were hanging out with friends at 3 a. m. and going to the bar and wanted to see what was open," said Walter Choo, 40, of Fort Greene. The smartphone-like glasses will likely come out this year and cost between $250 and $600, the Times said, possibly including a variation of augmented reality, a technology already available on smartphones and tablets that overlays information onto the screen about one's surroundings. So, for example, if you were walking down a street, indicators would _ showing you the nearest coffee shop or directions could be plotted out and come into view right on the sidewalk in front of you. "As far as a mainstream consumer product, this just isn't something anybody needs," said Sam Biddle, who writes for Gizmodo.com. "We're accustomed to having one thing in our pocket to do all these things," he added, "and the average consumer isn't gonna be able to afford another device that's hundreds and hundreds of dollars." Google publisher Seth Weintraub, who has been reporting on the smartphone-like glasses since late last year, said he is confident that this type of wearable device will eventually be as common as smartphones. "It's just like smartphones 10 years ago," Weintraub said. "A few people started getting emails on their phones, and people thought that was crazy. Same kind of thing. We see people bending their heads to look at their smartphones, and it's unnatural," he said. "There's gonna be improvements to that, and this is a step there.

Can you imagine traveling to work in a one-man submarine? Scientists believe that someday one-man submarines will be as numerous as automobiles today. One says," One day soon, men will walk on the ocean floor as they do on the street. " Perhaps during your life time, people will travel, work and live under the sea. Ships carrying oil and articles of trade will move beneath the ocean. Passenger ships will be built to travel underwater, where storms cannot delay them or make people seasick. Special underwater ships will be designed for mining, fishing, and exploring unknown areas. For military use, there may be submarines that can fly and then dive underwater to approach the battle area without being seen. First, however, the human problems associated with living in the ocean will need to be studied in detail. Many of these problems are the same as the problems of living in outer space: pressure, lack of oxygen, and weightlessness. Already scientists have begun to study these problems. In 1963 and 1964 scientists and Navy divers lived and worked underwater for several days in two projects which were called Sealab I and Sealab II. The Sealab II experiment kept the scientists and divers 215 feet below the surface for thirty days, studying marine biology, temperature, pressure, currents, and ocean bottom geology. Many puzzling questions remain unanswered, however. Man's warm blood makes it difficult for him to live long in the sea without some kind of warmth. Can our blood be changed to fit new water surroundings? What will happen to our muscles if we live in the water very long? Will they become soft away from our usual land existence? Will bones become weak and our blood pressure change? Scientists are searching for answers. By studying plants and animals deep in the ocean, scientists may find a cure for some of our most serious human diseases. We may learn to use plants to increase our world food supply. Engineers may learn to use the power of the sea by building huge walls to catch the force of the tides. According to the author,in future,passenger ships might be the ones that can _

Lee Kuan Yew, former prime minister of Singapore, died on Monday, March 23, 2015, at the age of 91, according to a statement released by the Prime Minister's Office. Lee, a Cambridge-educated lawyer, is widely credited with building Singapore into one of the world's wealthiest nations. He co-founded the People's Action Party (PAP), which has ruled Singapore since 1959 and led the newly born country when it was separated from Malaysia in 1965. In Beijing's eyes, Lee Kuan Yew, the late founding father and leader of Singapore, was not only "an old friend of the Chinese people", but also "the founder of China-Singapore relations", according to China's previous official news releases about his visits. Chinese media estimated that he had been to China more than 20 times, and he was known for his good personal relations with China's top figures, especially former leader Deng Xiaoping. Zhang Jiuhuan, the Chinese ambassador to Singapore from 2000 to 2004, noted that "it was a _ case" at the time that a foreign prime minister would visit China, as Lee did in 1976, in the absence of diplomatic relations between the two nations. Deng then paid back the visit, going to Singapore in 1978, in what Zhang described as a sensational trip. Jin Canrong, a professor of international relations at Renmin University of China in Beijing, noted that Lee's No 1 contribution to China was his efforts in "sharing Singapore's successful experience in governance", adding that "China has benefited a lot" from this. The China-Singapore Suzhou Industrial Park, inaugurated in February 1994 in Jiangsu province in East China, was proposed by Lee, who even went to the city in 1992 to inspect the site for the park. Now, with the park serving as a role model for China's economic cooperation with foreign countries, more such industrial parks hosted or co-hosted by China have been established domestically and abroad. According to the passage, which of the following is FALSE?
Choices:
A. Lee passed away at the age of 91.
B. Lee visited China in 1976.
C. Lee had a good personal relation with Deng Xiaoping.
D. The opening of the China-Singapore Suzhou Industrial Park was in February 1992. | D |

Over the years, I missed Linda very much, I wanted to share happiness of my children and then grandchildren , And I needed to share my sadness when my brother and then moth-er died, There was an empty place in my heart that only a friend like Linda could fill. One day, I was reading a newspaper when I noticed a photo of a young woman who looked very much like Linda and whose last name was Wagman --Linda's married name."There must be thousands of Wagmans."I thought, but I still wrote to her. She called as soon as she got my letter, "Mrs , Tobin!"she said excitedly, "Linda Ev-ans Wagman is my mother." Minutes later I heard a voice that I recognized at once, even after 40 years ,We laughed and cried and caught up on each other's lives, Now the empty place in my heart is filled, And there's one thing that Linda and I know for sure; We won't lose each other again! They haven't kept in touch _ .

mmlu | Question:
One day, President Lincoln went to a party. At the gathering, a man called Douglas was repeatedly talking about Lincoln's low position in life and saying that he first met Lincoln when he was a shop assistant at a village shop. Finally he said, "And Mr. Lincoln was a very good waiter too." People burst into laughter, but they quieted down when Mr. Lincoln said quietly. "Gentlemen, what Mr. Douglas has said is true. I did keep a grocery , and I did sell cotton, candles and cigars, and sometimes whiskey . But I remember that in those days Mr. Douglas was one of my best customers. I often stood on one side of the counter and sold whiskey to Mr. Douglas on the other side, but the difference between us now is: I have left my side of the counter, but Mr. Douglas still sticks to his as firmly as ever."

A. By telling about his low position in life in his early days.
B. By making fun of Douglas' low position now.
