Born in 1936 in Oak Park, Illinois, the American Richard Bach is the direct descendant of J.S. Bach, the famous composer. He attended Long Beach State College in 1955. As an airplane pilot, Bach got married to his first wife and had six children, but divorced later and then left his family because he didn't believe in marriage. Everything concerning airplane was his field, including an aviation technical writer and flight instructor. Though aviation was his true love, Bach always wanted to write. During his high school years, one of his teachers made him realize his potential. In 1959 he had this idea of a bird learning to pass beyond the walls of limitations--Jonathan Livingston Seagull. In almost all his books he used airplanes as a way to pass the message. In Running from Safety, Bach shares with us his childhood: at age 8, he lost one of his brothers: Bobby. In 1970, Jonathan Livingston Seagull, a story about a seagull who flew for the sake of flying rather than merely to catch food, was published by Macmillan Publishers after the manuscript was turned down by many other publishers. The book, which included unique photos of seagulls in flight, became a best-seller. In 1973, the book was turned into a movie. It's said that Bach charged the production with changing the movie without his permission. In fact, those who saw the movie noticed that his name wasn't mentioned. Bach used to be all the following EXCEPT _ .
Choices:
A. a pilot
B. a writer
C. an instructor
D. a fighter | D |

Money is the root of all evil and new study claims there may be some truth behind the saying.Scientists at the University of California, Berkeley, US,announced on February 27 that rich people are more likely to do unethical things, such as lie or cheat, than poorer people. The scientists did a series of eight experiments. They published their findings online in the Proceedings of the National Academy of Sciences (PNAS,<<>> ). They carried out the first two experiments from the sidewalk near Berkeley. They noted that drivers of newer and more expensive cars were more likely to cut in on other cars and pedestrians at crosswalks. Nearly 45 percent of people driving expensive cars ignored a pedestrian compared with only 30 percent of people driving more modest cars. In another experiment, a group of college students was asked if they would do unethical things in various everyday situations. Examples included taking printer paper from work and not telling a salesperson when he or she gave back more change. Students from higher-class families were more likely to act dishonestly. According to the scientists, rich people often think money can get them out of trouble. This makes them less afraid to take risks. It also means they care less about other people's feelings. Finally,it simply makes them greedier."Higher wealth status seems to make you want even more,and that increased want leads you to bend the rules or break the rules to serve your self-interest," said Paul Piff, leading scientist of the study. Piff pointed out that the findings don't mean that all rich people are untrustworthy or that all poor people are honest. He said the experiments were to show how people living in different social situations express their instincts and values in different ways. What does the article really want to show us?
Choices:
A. Money is the root of all evil.
B. The rich are more likely to act badly.
C. The saying is unreasonable.
D. All rich people are untrustworthy. | B |

mmlu | Question:
Ever wondered how one person could save the planet from the effects of climate change? A British-made computer game on trial release on Monday creates different ways of doing just that. "Fate of the World"puts the Earth's future in players' hands, placing them in charge of an international environmental body which could save the world from the effects of rising greenhouse gas emissions or let it destroyed by more emissions. Through different scenes, players can explore options such as geoengineering and alternative energy sources to save the planet from rising temperatures, decreasing natural resources and a growing population over the next 200 years. An improved version of the game will be followed by a three-month feedback period from players, with final release due in February next year. Created by Oxford-based games developer Red Redemption, the game is different from other mainstream action games mainly by using data from real climate models and advice from scientists and economists. "Science data is often inaccessible and we are trying to put players in a position of power and connected with the issues," Gobion Rowlands, Red Redemption's founder and chairman said. This year, a series of apparent errors in climate science and the failure of UN talks to reach an international deal to cut greenhouse gas emissions appeared to weaken the public's interest in climate change. However, games centered on sustainability and human rights have been growing in popularity and are welcomed by green groups as a way of raising awareness. Using climate change as inspiration for entertainment shows the issue has affected global culture, which can only be a good thing.Friends of the Earth's head of climate Mike Childs said."We need creative industries to work with these big issues as the results can be extremely powerful and can help us to understand what a sustainable future looks and feels like,"he added. Which of the following can NOT the players experience while playing the new game?
Choices:
A. Challenging the climate change in an unreal world
B. Understanding what a sustainable future looks and feels like
C. Enjoying the power to decide the earth's fate
D. Predicting what will happen in 200 years | D |

mmlu | Question:
We all enjoy the beautiful show of color1s as leaves change each autumn. But did you ever wonder how and why this happens? To answer the question, first you have to understand what leaves are and what they do. Leaves are nature's food factories. Plants take water from the ground through their roots. And they take a gas called carbon dioxide from the air. Plants use sunlight to turn water and carbon dioxide into glucose . Glucose is a kind of sugar. Plants use glucose as food for energy and as a building block for growing. The way plants turn water and carbon dioxide into sugar is called photosynthesis . That means, "putting together with light". A chemical called chlorophyll helps photosynthesis. Chlorophyll is what gives plants their green color1. As summer ends and autumn comes, the days get shorter and shorter. This is how trees "know" to begin getting ready for winter. During winter, there is not enough light or water for photosynthesis. Trees rest during this time and live off the food they stored during the summer. They begin to shut down their food-making factories. The green chlorophyll disappears from the leaves. As the bright green fades away, we begin to see yellow and orange leaves. Small amounts of these color1s have been in the leaves all along. We just can't see them in the summer, because they are covered up by the green chlorophyll. The bright reds and yellows we see in leaves are made mostly in autumn. In some trees, like maples, glucose is caught in the leaves after photosynthesis stops. Sunlight and the cool nights of autumn turn this glucose into a red color1. The brown color1 of trees like oaks is made from waste left in the leaves. It is the mixture of all these things that makes the beautiful color1s we enjoy during autumn. What's the author's purpose of writing the passage?
Choices:
A. To explain the process of trees' photosynthesis.
B. To encourage readers to protect the environment.
C. To analyze the reasons why leaves change color1s.
D. To help readers understand what leaves and trees are. | C |

LONDON(Reuters)--Quiet please--Britain's Queen Elizabeth is preparing to have her swans counted. Buckingham Palace has announced that the annual Swan Upping, a tradition dating back to the 12th century which involves a counting of the swan population on the River Thames, will be conducted by the Queen's official Swan Marker from July 20 to July 24. "With the assistance of the Queen's Swan Warden, Professor Christopher Perrins of the University of Oxford, the swans and young cygnets are also assessed for any signs of injury or disease," Buckingham Palace said in announcing the count. The process involves the Swan Marker, David Barber, rowing up the Thames for five days with the Swan Warden in traditional wooden boats while wearing special scarlet uniforms and counting, weighing and measuring swans and cygnets. It may seem strange, but it is very important to the Queen. According to custom, Britain's queen or king owns all unmarked, mute swans in open water, but the Queen now exercises the right only on areas of the Thames and its nearby _ In medieval times, the Swan Marker would not only travel up the river counting the swans, but would catch as many as possible as they were sought after for banquets and feasts. This year, the Swan Marker and the Swan Warden are particularly keen to discover how much damage is being caused to swans and cygnets by attacks from dogs and from abandoned fishing tackle . It is also an important year because Queen Elizabeth has decided to join her team of Swan Uppers for part of the census. She will follow them up the river and visit a local school project on the whole subject of swans, cygnets and the Thames. "Education and conservation are essential to the role of Swan Upping and the involvement of school children is always a rewarding experience," Buckingham Palace said. We can infer from the passage that the process of counting the swans _ .

A. remains almost unchanged in the past years
B. involves a lot of royal members
C. sometimes lasts longer than before

Tigers are the largest wild cats in the world. They usually go out to hunt for food when it is dark. When a tiger sees an animal, it moves quickly and then jumps on the animals to kill it. Sometimes it can take the tiger several days to finish eating its food. When the tiger is full, it will cover the dead animal with leaves. Later, when the tiger is hungry again, it comes back to eat some more. Tigers are different from others in the cat family: they like water and often jump into rivers to swim. Some tigers live in very cold places in North Korea, Russia and China. Other tigers live in warmer places--in India and parts of Southeast Asia. But now all tigers are in danger. Some people kill tigers to use their skins for clothes, and their bodies for medicine. There is also less and less land for tigers to live in. ,. Tigers mainly live in _ .

mmlu | Question:
Isn't it interesting how we expect others to behave in a certain way so we can feel good about ourselves? And then when people don't behave as we want them to, we feel so disappointed and angry --- when really, most times, we're not actually surprised at their actions? We just want those actions to be different --- actions we'd be more comfortable with. This week I shared a friend a wonderful home-cooked meal and a bottle of wine. About the time we got to the freshly-baked cookies, the conversation turned to her somewhat crazy sister. I had to smile, just a little, since her sister-stories had had much the same theme for the last two decades.When her frustration was just about to peak over her sister's latest unbelievably selfish act, I suggested she begin trying "The Law of Patient Acceptance." "How can I possibly accept her behavior?" my friend asked. "Acceptance doesn't necessarily mean tolerance," I shared. "It just means that you accept the person for who they are and you stop knocking yourself out trying to change them." Everyone has these difficult people in their lives from time to time. "Think of it this way," I said. "If you were to go out and buy an ottoman today, thinking you were buying a chair, you'd be really angry that the ottoman was such a pathetic chair. But once you realize what you're dealing with, once you accept the ottoman for what it is and you stop trying to turn it into a chair, your anger largely goes away." You have to accept people for who they are. Even when you've had high hopes that they might have been able to be someone else. "You can't change people," my Mother always said. And she was right. The best we can do is to see people as clearly and objectively as possible. For they rarely change. By mentioning the example of buying an ottoman, the writer intends to explain _ .
Choices:
A. how "The Law of Patient Acceptance" works
B. what the meaning of "The Law of Patient Acceptance" is
C. why greed and selfishness exist
D. when we should use "The Law of Patient Acceptance" | A |

I still clearly remember that day. I was on the side of the road for close to four hours with my big Jeep. I put signs in the windows that said, "NEED A JACK ". Right as I was about to give up, a truck stopped and a man got off. He sized up the situation and went back to take a jack. After about two hours, we finished the job with sweats. We were both dirty. His wife produced a large water jug for us to wash our hands in. I tried to put $20 in the man's hand, but he wouldn't take it, so instead I went up and gave it to his wife as quietly as I could. I thanked them up one side and down the other. I asked the little girl, their daughter, where they lived, thinking maybe I'd send them a gift. She said they lived in Mexico. They were in Oregon now so Mommy and Daddy could pick cherries for the next few weeks. After that, they were going to pick peaches, and then go back home. After I said my goodbyes and started walking back to the Jeep, the girl called out and asked if I'd had lunch. When I told her no, she ran up and handed me a tamale . I thanked them again and walked back to my car. When I opened the tamale, what did I find inside? My $20 bill! I ran to the van and the guy rolled down his window. He saw the $20 in my hand, started shaking his head smiling, and with what looked like great concentration said in English: "Today you, tomorrow me." Then he rolled up his window and drove away, with his daughter waving to me from the back. This family, working on a seasonal basis where time is money, took a couple of hours to help a stranger while others passed by quietly. Since then I've helped many people like the Mexican family. I didn't accept money. But every time I was able to help, I felt as if I was putting something in the bank. From the passage we know that _ .

mmlu | Question:
I have had just about enough of being treated like a second-class citizen, simply because I happen to be that unfairly treated member of society --- a customer. The more I go into shops and hotels, banks and post offices, railway stations, airports and the like, the more I am convinced the things are being run merely to suit the firm, the system, or the union. There seems to be a deceptive new motto for so-called "service" organizations --- Staff Before Service. How often, for example, have you queued for what seems like hours at the Post Office or the supermarket because there was not enough staff on duty to manage all the service grilles or checkout counters? Surely in these days of high unemployment it must be possible to hire cashiers and counter staff. Yet supermarkets, hinting darkly at higher prices, claim that uncovering all their cash registers at any one time would increase operating costs. And the Post Office says we cannot expect all their service grilles to be occupied "at times when demand is low". It is the same with hotels. Because waiters and kitchen staff must finish when it suits them, dining rooms close earlier or menu choice is cut short. As for us guests, we just have to put up with it. There is also the nonsense of so many friendly hotel night porters having been thrown out of their jobs in the interests of "efficiency" and replaced by coin-eating machines which offer everything. Not to mention the tea-making kit in your room a kettle with a mixed collection of tea bags, plastic milk boxes and lump sugar. Who wants to wake up to a raw teabag? I do not, especially when I am paying for "service". Can it be stopped, this worsening of service, this growing attitude that the customer is always a trouble? I angrily hope so because it is happening, sadly, in all walks of life. Our only hope is to hammer home our anger whenever and wherever we can and, if all else fails, bring back into practice that other, older slogan --- Take Our Deal Elsewhere. According to the writer, long queues at counters are caused by _ .
Choices:
A. not having enough male staff on duty
B. difficulties in hiring more efficient staff
C. not providing enough staff on purpose to reduce budget
D. lack of cooperation between staff members | C |
mmlu | Question:
Elshijh, an Egyptian doctoral candidate at Beijing Language and Cultural University, said he felt fairly excited when he learned that Mo Yan had won the literary prize. "Mo's winning of the prize is pushing Egypt to translate more of his works into Arabic," Elshijh said, adding that there is already an Arabic edition of "Red Sorghum," but Egypt's Ministry of Culture recently announced that it will translate another of Mo's works from Chinese to Arabic. Although Chinese literature is getting more attention around the world, translated versions of Chinese works remain in small supply in places like the United States and Europe. Jonathan Chuck, an American who has been working in social media for three years in China, has read some ancient Chinese classics in Englishand can name several ancient poets such as Li Bai. Chuck said works of Chinese literature are hard to get in the United States, as bookstores simply don't carry many English translations. "Besides, China is considered a mysterious country and far away from our daily life." Chuck said when he was in school, pupils mostly studied Western literature translated from French, German and Portuguese, not literature translated from Asian languages. "China's Nobel prize will inspire more Westerners to notice Chinese literature, and I may read some of Mo's works," he added. Li Ling, a professor at Beijing Language and Cultural University, said Chinese literature has less of a market than English-language literature because Western culture is the dominant culture. Moreover, it is difficult to fully express some Chinese words in English, which can limit Chinese literature to a Chinese-literate audience, Li added. "Western readers are more picky about what they read," he said, explaining that if a Chinese book is not translated well, it would be " _ " to recommend it to Western readers.

Throughout seafaring history, ships and sailors have been lost to storms, accidents and war. Until recently, most of these ships were weak wooden sailing vessel , their skeletons quickly eaten away by sea creatures. Now, large vessels made of steel float on the seas. Thousands of these huge ships have been lost in times of war and in times of peace. The bones of great metal ships, unlike the wooden vessels of old, survive the destruction of the sea long enough to become home and harbor for underwater life of all kinds. Shipwrecks often provide the only hard surface and structure at the sandy bottom of the sea, something many sea creatures need. The ship has been underwater for only five days. Its surface is still clean. Six weeks later, the wreck is covered with a slimy layer of algae , but it is still recognizable as a ship. Soon, animals that need to attach themselves to a hard surface, like the feather duster worms, make the wreck their home. In warm waters, coral polyps settle on the wreck and begin the process of building a rock-like _ on the ship. Small fish are attracted on all of these creatures. Larger fish come to feed on these small fish that hide in the wreckage. Eventually, the largest animals are attracted to the rich life on the shipwreck. Shipwrecks give us valuable information about how sea plants and animals develop. We know exactly how long this wreck has been under water and how long sea life has been growing on it. Yet even the strongest steel shipwreck will finally be destroyed by the flows of water. But long after this wreck has been broken apart, it will still act as a reef . Layer upon layer of sea life has formed a structure that is now more natural than artificial, and will remain an island of life under the sea. Which of the following is NOT TRUE about shipwrecks?
Choices:
A. Most ships in ancient times sank easily and become shipwrecks.
B. Shipwrecks, for scientists, are worth researching to get valuable information.
C. The skeletons of old wooden shipwrecks will exist for quite a long time.

When I saw a big handmade signboard "Welcome Yuxin" at the airport,I knew I had found a caring family at the other side of the world -- the United States. My host mom had already decorated my room for me. There was a doll on one side of the room,and a bookcase full of books on the other -- they had heard I loved reading. Mom had also prepared a keyboard for me,since she knew that I played the piano. My life in the family did not go so well at first. Because I am the only child in my family in China,I was not used to having two younger kids -- Zachary and Grace--running around me yelling all the time. Mom had a serious talk with me about this problem on a Sunday afternoon. She told me,"You can't just come home from school every day,go to your room and do your homework. You need to be a part of this family. You need to play with my kids for at least an hour. " This rule was very annoying at first. I did not have much experience playing with children. However,the more time I spent with the kids,the more I grew to love them. We played games and read books together. I even taught them Chinese. Thanks to Mom's rule,I began to feel like I was really part of the family. Mom also inspired me to live a healthier life. She got up early every morning to go running. On weekends,she took the whole family to visit parks or go camping. I did not like sports much when I was back home,but now I love to join all kinds of sports. I am healthier and more confident too. With my American family,I found joy and laughter. I learned to live with energy and optimism ,thanks to the care and responsibility of my loving American parents.

mmlu | Question:
If English is not your first language, it is a good idea to take English language classes to improve your written and spoken communication skills. There are many ways to learn English. You can learn from a book, a DVD, on the Internet or by attending classes. One of the most successful ways to improve your English is to join a course in a country where English is widely spoken. The more you practice, the more you will learn. But why learn the English language? English is an important language for anyone who is planning to travel or become involved in business. Many people love travelling, but if their English is poor, it can be difficult to understand signs, read directions and make themselves understood. Before travelling, it is important to understand the culture and customs of the places you visit. Learning basic English before you travel will help you to understand these customs and avoid mistakes that could be embarrassing. When you are travelling, you will also enjoy meeting new people. If you can speak English, you will have a better chance of being able to communicate with the people you meet. Many of your new friends will speak English and others will have English as a second language. Without English, your friendships will be limited as you travel around the world. If you are involved in business, it is important to be able to communicate in English. The Internet, world travel and modern communication systems have made the world seem like a much smaller place. These days business people interact with customers and other business people from all over the world. That makes your English language skills more important than ever.

mmlu | Question:
Recently,I came across an interesting article on the differences between British English and American English. I had a lot of fun reading it and thinking of as many differences as I could as an American. Their cars have "bonnets ", while ourselves have "hoods". They park their cars in a "car park" while we leave ours in a "parking lot". Our "cookies" are their "biscuits", while their "rubbers" are our "erasers". Then there are the food words. Would you want to eat something called "Toad in the Hole" or "Bangers and Mash" or "Spotted Dick"? I'm here to report they are all very tasty. There are American equivalents ,of course. We've got "Shoofly Pie", "Chicken Fried Steak" and "Mississippi Mud Pie". What they call "crisps" is what we call "potato chips" and when we ask for "chips" in England we will get what we know at home in America as "French fries". They find it _ that we call the "toilet" the "bathroom" and they really double over with laughter when we ask for the "restroom". American ladies in England who ask for the "little girl's room" or the "powder room" will be met with blank stares. A "fag" is a "cigarette" in the UK, which can lead to endless confusion for British visitors looking for a cigarette in America. Americans on the other hand are endlessly confused by English signs put up over doorways saying "Way Out". We Americans walk on the sidewalk not the pavement. "Pavement" in America is the actual cement the sidewalk is made of. The examples given at the end of the passage mainly show that _ .

A. Americans don't like dealing with the British
B. English signs are very hard for people to understand
C. American English is very different from British English.

I opened my eyes and found the doctors were standing by my bed. They had some welcome news. I had been living in the bone marrow transplant unit of the famous cancer center for a month. The doctors told me that while my immune system was still very weak, my brother Adam's healthy cells were beginning to work in my bone marrow. I was showing signs of progress: I was able to walk around---slowly---without assistance, my blood counts were going in the right direction, and I no longer needed to be connected continuously to an IV machine. It was the"graduation"day. The doctors were sending me to the Hope Room, a halfway house sponsored by the American Cancer Society. I would live there for the next three months and would be cared for by my boyfriend, Seamus, who is again helping me write this column for Internet readers as I regain my strength. Pushed out of the hospital in a wheelchair, I took my first breath of fresh air in weeks. But before I could enjoy this moment, my mother helped me put on a mask. I gave her an annoyed look, but I knew she was right. For the immediate future, I would need to wear gloves and a mask wherever I wanted to go in public. No subways, no crowds. However, I can enjoy my freedom, even if cancer continues to limit my choices. My new freedom means not being waken up every couple of hours by a nurse with pills in her hand, not seeing doctors with their masks and their caring, and not being connected to an IV machine 24 hours a day. Freedom also means being patient with my mother and boyfriend, who try hard to cook for me in the kitchen and make sure I don't fall off my chair in the shower. Freedom is the responsibility to take medicine on time. Freedom also means returning to the hospital several times a week to receive follow-up examinations. But all is well worth. You surely know the reason. I love every one of my family and I love Seamus. The author regarded the day as"graduation"day most probably because she would _ .

C. come out of hospital and live in her own home
D. no longer need to write the column for Internet readers | B |
mmlu | Question:
Interest in pursuing international careers has risen in recent years strengthened by permanent personnel shortages that are causing companies to search beyond their home borders for talent. Professionals seek career experience outside of their home countries for a variety of reasons. They may feel the need to recharge their batteries with a new challenge. They may want a position with more responsibility that encourages creativity. Or they may wish to expose their children to another culture, and the opportunity to learn a second language. When applying for a job, one usually has to submit a resume or curriculum vitae (CV). The two terms generally mean the same thing: a one--or two--page document describing one's educational qualifications and professional experience. However, guidelines for preparing a resume are constantly changing. The best advice is to find out what is appropriate regarding the company culture, the country culture, and the culture of the person making the hiring decision. The challenge will be to include two or more cultures in one document. The following list is a good place to start. "Educational requirements differ from country to country. In almost every case of 'cross--border' job hunting, just stating the title of your degree will not be an adequate description. Provide the reader with details about your studies and any related experience. " Pay attention to the resume format you use-chronological or reverse-chronological order. Chronological order means listing your 'oldest' work experience first. Reverse-chronological order means listing your current or most recent experience first. Most countries have preferences about which format is most acceptable. If you find no specific guidelines, the general preference is for the reverse-chronological format. " If you are submitting your resume in English, find out if the receiver uses British English or American English because there are changes between the two versions. For example, university education is often referred to as 'tertiary education' in the United Kingdom, but this term is almost never used in the United States. A reader who is unfamiliar with these changes may assume that your resume contains errors. When it comes to resume writing, it is best to _ .
Choices:
A. take cultural factors into consideration
B. learn about the company's hiring process
C. follow appropriate guidelines for job hunting
D. know the employer's personal likes and dislikes | A |
mmlu | Question:
I went over my grandmother's house today and she didn't have time for me. You see, the lady's husband downstairs died and my Grandmother wanted to make some cookies for her. My grandmother did not analyze how the lady treated her, or if the lady needed any cookies, or even if the lady would like the cookies. She didn't think how much the lady has done for her. She simply began baking. My Grandmother turned 94 last week and this I believe is her secret to life. My grandmother is generous and hard-working in a way that is rare for our time. She lives by a simple belief: if someone needs your help, you help. Never mind all the analyzing and thinking whether the person deserves or appreciates the help. My grandmother doesn't sit around thinking about who might be making use of her: she simply does what is needed. At 94, she is busy in life. She is making a blanket for a new great grandchild, and worried that I don't have enough kitchen towels for my home. She is bringing soup to a sick neighbor, and teaching the new wife of her cousin (who is 88) how to cook Italian food. My grandmother had every right to give up, but she didn't -- and amazingly life did bring her good things, like a husband with twinkling blue eyes who was much ahead of his time and believed that men should do an equal amount of cooking and cleaning in the home, three beautiful children (my father and two aunts), 22 grandchildren, and five great grandchildren. My grandmother is not afraid to give someone she barely knows a bowl of soup. She never keeps herself out of the world. Which of the following is NOT true according to the passage?

A. My grandfather does not treat women in an unfair way
B. My grandmother cares for her children even some strangers.

Jack used to curse the front yard as if it were a living thing. He was the man who lived with my grandmother for thirty years.

Some time people call each other "scared-cat",but have you ever thought about this expression? When a cat is frightened,its heart starts beating faster,its muscles get tense,and there are changes in the chemicals in its bloodstream.Although the cat doesn't realize this,its body is getting ready for action.If the danger continues,the animal will do one of two things:It will defend itself,or it will run away as fast as it can. Something like this also happens to people.When we are excited,angry,scared,or aroused by other emotions (feelings),our bodied go through many physical changes.Out hearts beat faster,and our muscled get tense.All of these changes make us more alert and ready to react.We,too get ready to defend ourselves or run. Human beings,however,have a problem that animals never face.If we give way to our feelings and let them take over,we can get into trouble.Have you ever said something in anger--or hit somebody--and regretted it later? Have you ever shouted at a teacher,told somebody you were lonely,or said you were in love,and then wished later you had kept your mouth shut? It isn't always wise to express your feelings freely. Does this mean that it's smarter always to hide our feelings? No! If you keep feelings of anger,sadness,and bitterness hidden away or bottled up inside,your body stays tense.Physical illness can develop,and you can feel _ inside.It can actually be bad for your health.(It isn't good to keep pleasant feelings inside either;all feelings need to be expressed.) Feelings that you keep all bottled up inside don't just go away.It's as if you bought some bananas and stuck them in a cupboard.You might not be able to see them,but before long you'd smell them.And if you opened the cupboard,chances are you'd see little fruit flies hovering all over them.They'd be rotten.

There have been many great inventions that changed the way we live.The first great invention was one that is still very important today--the wheel.This made it easier to carry heavy things and to travel long distances.For hundreds of years after that there were few inventions that had as much effect as the wheel.Then in the early 1800's the world started to change.There was little unknown land left in the world.People did not have to explore much anymore.They began to work instead to make life better.In the second half of the 19th century many great inventions were made.Among them were the camera, the electric light and the radio.These all became a big part of our life today.

A chocolate printer that allows sweet lovers to create 3D desserts by themselves is to go on sale at a cost of 2,500 pounds. The machine squirts out chocolate and, via computer instructions, allows the user to build any shape they like out of the food. But makers Choc Edge have missed the Easter rush. Even so, they hope the printer will be snapped up by retailers immediately they come to the market. Britain's biggest chocolatiers Thornton's have already said they are interested. Because of the high cost, however, few individuals are likely to buy one. But the devicecould one day allow people to design their own 3D objects after submitting their designs on a website. Dr Hao, founder of Choc Edge came up with a prototype last year and has only just perfected it so that it can now go on sale. "We've improved and simplified the machine, so now it is really easy to use," he told the BBC. "You just need to melt some chocolate, fill a syringe that is stored in the printer, and get creative printing of your chocolate." 3D printing is a technology where a three dimensional object is created by building up successive layers of material. The technology is already used in industry to produce plastic and metal products, but this is the first time the principles have been applied to chocolate. The research has presented many challenges. Chocolate is not an easy material to work with because it requires accurate heating and cooling cycles. Dr Hao said, "What makes this technology special is that users will be able to design and make their own products. From reproducing the shape of a child's favourite toy to a friend's face, the possibilities are endless. It could be developed to help consumers design many products from different materials, but we've started with chocolate as it is easily available, low cost and harmless." "There is also no wastage as any spoilage can be eaten." Dr Hao added, "Eventually we may see many mass-produced products replaced by unique designs created by the customer."[:] EPSRC chief executive Professor Dave Delpy said, "This is a good example of how creative research can be applied to create new manufacturing and retail ideas. By combining developments in engineering with the commercial potential of the digital economy,We can see the new market prospect --creating new jobs and, in this case, the chocolate printer is called sweet business opportunities."

I used to watch her from my kitchen window. She seemed so small as she muscled her way through the crowd of boys on the playground. The school was across the street from our home and I would often watch the kids as they played during break. I remember the first day I saw her playing basketball. I watched in wonder as she ran circles around the other kids. She managed to shoot jump shots just over their heads and into the net. The boys always tried to stop her but no one could. I began to notice her at other times, basketball in hand, playing alone. One day I asked her why she practiced so much. Without a moment of hesitation she said, "I want to go to college. The only way I can go is to get a scholarship. I am going to play college basketball. I want to be the best. My Daddy told me if the dream is big enough, the facts don't count." Well, I had to give it to her--she was determined. I watched her through those junior high years and into high school. Every week, she led her school team to victory. One day in her senior year, I saw her sitting in the grass, head in her arms. I walked across the street and sat down in the cool grass beside her. Quietly I asked what was wrong. "Oh, nothing," came a soft reply, "I am just too short." The coach told her that at 5'5" she would probably never get to play for a top ranked team--much less offered a scholarship--so she should stop dreaming about college. She was heartbroken and I felt my own throat tighten as I sensed her disappointment. I asked her if she had talked to her dad about it yet. She told me that her father said those coaches were wrong. They just did not understand the power of a dream. He told her that if she truly wanted a scholarship and that nothing could stop her except one thing -- her own attitude. The next year, as she and her team went to the Northern California Championship game, she was offered a scholarship and on the college team. She was going to get the college education that she had dreamed of. Why was the girl heartbroken?
Choices:
A. She was considered too short to be a top player.
B. Her coach stopped her training because of her height.
C. She couldn't be on a college basketball team.
D. She wouldn't be admitted by an ideal college. | A |

Toyota Motor Corp, Japan's biggest carmaker, said on Friday it will recall 1,489 Lexus sedans sold in China. "It will take us some time to ship the fuel tanks and vent pipes to China to change those in these Lexus sedans for customers free of charge, if problems are found," said Yang Hongjian, a spokes- woman of Toyota's China representative office. The expected recall will affect Lexus LS430 sedans made in Japan from July 29, 2003 to January 14, 2004, the representative office said in a statement. Toyota has not received complaints from Chinese customers, according to the statement. The move will be part of Toyota's global recall of 18,200 Lexus LS430s. It will be the third car recall in China in two weeks. Although automobile recall is a common practice in developed markets, it remains new to Chinese customers. The Chinese government published long-awaited automobile recall rules on March 15, which will be officially carried out at the beginning of October. China's auto market is forecast to reach 10 million units by 2010. Automakers, especially Chinese producers, will face greater pressure from automobile recalls, which could be very costly sometimes, and should be in full preparations, according to the expert. The Japanese carmaker sold 1, 549 Lexus vehicles on the Chinese mainland during the first five months of this year, according to Yang. Lexus sales on the mainland reached 4,000 units last year, up from 1,600 units in 2002. (China Daily July 3, 2004) The carmakers were unwilling to recall their cars in the past mainly because _ .
Choices:
A. they were not fully prepared
B. they couldn't afford the cost for their car recalls
C. their products could not meet the required standard

To Whom It May Concern: On March 5, 2012 , I bought a Perfect Muffin Kit from your store at Midfield Shopping Center. The cashier who assisted me was George. George was very friendly and told me that the Perfect Muffin Kit would live up to the guarantee on the box: "Perfect Muffins Every Time!". Unfortunately, this product did not live up to what it promised . The muffins I made were far from perfect . I followed the directions in the package very carefully . First , I removed the bag of mix from the box. Then , I poured it into a bowl. Next, I added the correct amount of water to the mix and stirred it. According to the directions, after stirring the mixture , I added half a cup of dried grapes, nuts , berries, or another favorite ingredient . My favorite ingredient happens to be hot sauce . I find that a bit of hot sauce makes pizza and soup taste very delicious. So, continuing to follow the directions, I added half a cup of hot sauce to the mix and stirred it. Finally, I poured the mix into muffin tins and baked it in the baker at 350 degrees for exactly 20 minutes. When the muffins finished baking, I was very excited to eat the "Perfect Muffins" as promised on the box. You can imagine my disappointment when, upon tasting the muffins, I discovered that they were not perfect. These muffins were , in fact , absolutely terrible. Not even my dog was interested in eating these supposedly "perfect" muffins. I would appreciate a full refund( money to be returned) of $3.99 for this product as soon as possible. Enclosed are the receipt, the empty box, and one of the un-perfect muffins so that you can experience it for yourself . Thank you for your attention to this matter.

mmlu | Question:
You are given many opportunities in life to choose to be a victim or creator. When you choose to be a victim, the world is a cold and difficult place. "They" did things to you which caused all of your pain and suffering. "They" are wrong and bad, and life is terrible as long as "they" are around. Or you may blame yourself for all your problems, thus internalizing your victimization. The truth is, your life is likely to stay that way as long as you feel a need to blame yourself or others. Those who choose to be creators look at life quite differently. They know there are individuals who might like to control their lives, but they don't let this get in the way. They know they have their weaknesses, yet they don't blame themselves when they fail. Whatever happens, they have choice in the matter. They believe their dance with each sacred moment of life is a gift and that storms are a natural part of life which can bring the rain needed for emotional and spiritual growth. Victims and creators live in the same physical world and deal with many of the same physical realities, yet their experience of life is worlds apart. Victims relish in anger, guilt, and other emotions that cause others---and even themselves---to feel like victims, too. Creators consciously choose love, inspiration, and other qualities which inspire not only themselves, but all around them. Both victims and creators always have choice to determine the direction of their lives. In reality, all of us play the victim or the creator at various points in our lives. One person, on losing a job or a special relationship, may feel as if it is the end of the world and sink into terrible suffering for months, years, or even a lifetime. Another with the same experience may choose to first experience the grief, then accept the loss and soon move on to be a powerful creative force in his life. In every moment and every circumstance, you can choose to have fuller, richer life by setting a clear intention to transform the victim within, and by inviting into your life the powerful creator that you are. What is the author's purpose in writing this passage?
Choices:
A. To define victims and creators.
B. To evaluate victims against creators.
C. To explain the relationship between victims and creators.
D. To suggest the transformation from victims to creators. | D |

mmlu | Question:
For thousands of years, the most important two buildings in any British village have been the church and the pub.Traditionally, the church and the pub are at the heart of any village or town, where the people gather together to socialize and exchange news. As a result, British pubs are often old and well preserved.Many of them have become historic sites.The most famous example is the pub in the city of Nottingham called " Ye Olde Trip to Jerusalem" , which dates back to the year 1189 AD and is probably the oldest pub in England. However, British pubs are not just for kings and queens; they welcome people from all classes and parts of society.On a cold night, the pub's landlord or landlady can always find a warm place for you by the fire.There is always honest and hearty food and plenty of drinks available at an affordable price. That's how things used to be.Things are beginning to change.It is said that the credit crunch is causing 39 British pubs in a week to go out of business.People do not have enough spare money to spend on beer.Recently, the UK government banned smoking in all pubs, and that may also have affected the number of customers going to pubs. This decline is happening despite the fact that in 2005 the UK government started to allow pubs to stay open after 11 p.m..Previously, with 11 p.m.as closing time, customers would have to drink quite quickly, meaning they sometimes got more drunk than they would if allowed to drink slowly.The British habit of drinking a lot very quickly is known as "binge drinking" , and it causes long-term health problems for people and problems with violent crime for communities. In order to save their businesses, pubs are trying to change with the market.British pubs now offer something for everyone.A lot of pubs used to be "Working Men's Clubs" , meaning that women could not usually enter.Today, however, women can freely enter 99% of pubs without experiencing any problems.Perhaps things are changing for the better after all. The passage mainly tells us _ .
Choices:
A. the long history of British pubs
B. the present situation of British pubs
C. the reason why British people go to pubs
D. the disadvantages of running pubs in Britain | B |

Mom was right!If you say thank you,for even the smallest gift or slightest show of kindness,you'll feel happy. Gratitude ,says Robert A.Emmons,a professor of psychology at the University of California,is an important element of happiness.In his recent book,Thanks!,Emmons uses the first major study on gratitude to prove mom's point.In acknowledging and developing this muchignored expression of thankfulness,he explains how people have benefited--even improved their health. As one of the leading scholars of the positive psychology movement,he admits gratitude may be difficult to express.He advises you to begin by admitting that life is good and full of events and elements that make daily existence a wonder.Second,recognize that the source of life's goodness is more than just you.That source may be your mom,a friend,partner,child,colleague at work or play,or any combination of these. Gratitude is always otherdirected,notes Emmons.You can be pleased or angry with yourself and feel guilty about doing something wrong,but you can never be grateful to or for yourself. Expressing gratitude shouldn't be a reaction;it should be a state of mind.To feel grateful when life is a breeze and you have more than you need is easy.To feel grateful in time of crisis--anger,hatred and bitterness--is easier.Also,too many people are aware of life's blessings only after these are lost.The voices expressing gratitude from his studies of individuals are many. It's crisis and chaos--danger,disease,disability and death--that bring many individuals to realize just how dependent they are on others.Yet it's the way each of us begins life and ends it.It's too bad that so many people waste those decades in between labouring under the illusion they are selfsufficient,says Emmons. To enable and embrace gratitude,Emmons encourages the readers of Thanks! to keep a gratitude diary.He even provides easytofollow directions on how to practise and develop gratitude. I'm not a reader or advocate of selfhelp books,but I am thankful for the reference I found in a newspaper article to the research Emmons was conducting on gratitude involving organ donors and recipients .The chance discovery led me to this book. Mom implied that kindness seems to find its way back to the giver because life really is all about giving,receiving and repaying.So I'll pay attention to her professional advice and say:Thank you,professor Emmons. What is the text mainly discussed?
Choices:
A. There are many ways of being thankful.
B. Gratitude is important to happiness.
C. Mom is great for her being thankful.
D. Being thankful will keep you fit. | B |
mmlu | Question:
Satellites play big roles in modern life. Some look downward to monitor environmental conditions on Earth.Others look outward in search of major solar flares that can trouble the transmission of electrical power to homes and businesses. Some spy on our enemies. Others relay communications around the globe. But all of these million-dollar wonders of technology can be knocked out by a collision with space junk ---debris ( )from satellites and other earthly technology orbiting high above the planet. Now,a teen from Jordan has designed a satellite to chase down space junk , collect it and then deal with it. Even bits of space junk as small as dots of paint pose a threat , says Dana. That's because this debris orbits our planet at speeds up to some 28,200 kilometers per hour. Such high speed explains why tiny paint dots have damaged the windshields of space shuttles so badly that they needed to be replaced. Researchers have come up with many ideas for getting rid of space junk. Some have suggested vaporizing small bits with lasers. Others have proposed launching satellites to collect the debris. Dana's design falls into this category. Here's how hers would work : A radar system aboard the satellite would scan and find a piece of space junk.Then,thrusters would change the satellite's orbit so that it could chase down _ . As the satellite closed in on its prey, cameras would keep it on target. At the last minute,a door that leads to a container would open. This container needs to be strong so that it doesn't break apart when the satellite swallows the space junk,Dana explains. Finally,when the trash container was full,it would be lowered toward the earth on a kilometer-long cable and its contents released into the upper atmosphere. There, the space junk would harmlessly burn up just like a meteor does. Meanwhile, her satellite would roll the container back up so that it could collect more trash. Why can small pieces of space junk threaten satellites?
Choices:
A. They travel at a very high speed.
B. They are difficult to track by satellites.
C. They can blow up into millions of pieces.
D. They are as soft as a ball in the air. | A |
mmlu | Question:
in order to know a foreign language thoroughly , four things are necessary. Firstly, we must understand the language when we hear it spoken. secondly, we must be able to speak it ourselves, with confidence and without hesitation . Thirdly, we must do much reading. Finally, we must be able to write it. We must be able to make sentences that are correct in grammar. There are no shortcuts to succeed in language learning. A good memory is a great help, but it is not enough only to memorize the rules from a grammar book. it is not much learning by heart long lists ( ) of words and their meanings, studying the dictionary and so on. We must learn by using the language. If we are pleased with a few rules we have memorized, we are not really learning the language. We must "learn through use". Practice is important. We must practice speaking and writing the language whenever we can. Someone hears and writes English very well, but he speaks it very badly. This is because _ .
Choices:
A. he doesn't understand the language when he hears it spoken
B. he doesn't have a good memory.
C. he always remembers lists of words and their meanings
D. he often hesitates to practice speaking it. | D |
mmlu | Question:
How often one hears children wishing they were grown-ups, and old people wishing they were young again. Each age has its pleasures and its pains , and the happiest person is the one who enjoys what each age gives him without wasting his time in useless regrets . Childhood is a time when there are few responsibilities to make life difficult. If a child has good parents, he is fed, looked after and loved, whatever he may do. It is impossible that he will ever again in his life be given so much without having to do anything in return. What's more, life is always giving new things to the child--- things that have lost their interest for older people because they are too well-known. But a child has his pains: he is not so free to do what he wishes to do; he is repeatedly being told not do something or being punished for what he has wrongly done. When a young man starts to earn his own living, he can no longer expect others to pay for his food, his clothes, and his room, but has to work if he wants to live comfortably. If he spends most of his time playing about in the way he used to as a child, he will go hungry. And if he breaks the laws of society as he used to break the laws of his parents, he may go to prison. If, however, he worked hard, keeps out of trouble and has good health, he can have the greatest happiness of building up for himself his own position in society. What is the main idea of the passage?
Choices:
A. Life is not enjoyable since each age had some pains.
B. Young men can have the greatest happiness if they work hard.
C. Childhood is the most enjoyable time in one's life.
D. One is the happiest if he can make good use of each age in his life. | D |

"Your homework is to collect sounds and take them down," Mrs. Olson said before class was over. She handed out sheets of paper shaped like giant ears. On his way home, Colin glared out of the school-bus window. Not fair, he thought. How could he collect enough sounds on his family's farm? If only he lived in the town. He got off the bus when it stopped at his mailbox. But he wasn't in the mood to wave as it drove away. "I'm home!"Colin called when he pushed open the gate. He threw his schoolbag down on a kitchen chair. "How was school?" His mother asked, walking in with his baby brother on her shoulder. "I've got homework," Colin complained. "Eat something before _ " His mother gave him the animal biscuits. Colin ate two tigers, three lions, and a seal, then drank some milk.

He quickly hopped off his bed and went to eat his breakfast. His mom had made pancakes, waffles, and eggs, but the boy felt like eating cereal. His mom had laid out his soccer clothes and after he was done with his breakfast, he couldn't wait to put them on.

mmlu | Question:
Will it matter if you don't take your breakfast? A short time ago, a test was given in the United States. People of different ages, from 12 to 83, were asked to have a test. During the test, these people were given all kinds of breakfasts, and sometimes they got no breakfast at all. Scientists wanted to see how well their bodies worked when they had eaten different kinds of breakfasts. The results show that if a person eats a right breakfast, he or she will work better than if he or she has no breakfast. If a student has fruit, egg, bread and milk before going to school, he will learn more quickly and listen more carefully. The result is opposite to what some people think. Having no breakfast will not help you lose weight. This is because people become so hungry at noon that they eat too much for lunch. They will gain weight instead of losing it. You will lose more weight if you your other meals. During the test, the people were given _ .
Choices:
A. no breakfast at all
B. different foods or nothing
C. very rich breakfast
D. little food for breakfast | B |

Friedrich Dobl, a Yugoslav working in Germany, was fed up with traffic jams. At long weekends and holiday times when he wanted to get him quickly he always found himself behind hundreds of other cars moving slowly along the notorious foreign workers' route through Germany and Austria. How easy it all was for police and emergency services. A siren, a flashing light? And like magic everyone was out the way. Going home from work one night he passed a garage. And there in front of him was the answer to his problems. An old ambulance was for sale. The red cross had been removed. But not the flashing light, and the siren. He tried the light. It flashed magnificently. He tried the siren. That too sounded impressive. He bought the ambulance and opened up for himself a dream world of motoring. It began early in the morning, all his luggage in the back of the ambulance and motorway in Germany looking reasonably clear. Soon, as always, a long line of traffic appeared ahead.

In record time he crossed the border into Austria. The big bluff was working. Police even waved him through the confusion caused by an accident. But then the Yugoslav made his big mistake. Until then he had only stopped for petrol. Now he was driving past a real accident, lights flashing , to late realize that it was not another traffic jam as he assumed. They stopped him, and after hearing the story of his ride across two countries fined him 12. 5 pounds. At long weekends and holidays Friedrich Dobl used to _ .

Mr. Hadley was my 6th grade teacher. At that time I was a short girl weighing 70 kilograms. Boys always laughed at me because of it. So I became an extremely shy young lady. One day Mr. Hadley told us that we would be required to come to the front of the class and read the reports that we had completed. When my turn came, I refused to stand in front of all those students and open up to their tricks. Mr. Hadley handed me my report and asked me to read it. I gave it back to him. He walked to the front and said,"Martha has a very good report here and I think everyone needs to hear her read it. If you make strange noises or make fun of her in any way, I will let you fail right here and now. OK?" Mr. Hadley walked back to me and handed me the paper again, asking me to go to the front of the class. I walked there on legs that were shaking and I felt a rabbit in my chest. Everyone was all quiet, including those boys. I stood there trying to be calm. Mr. Hadley walked over to me and put his arm around me,"You can do it. I have confidence in you!" His words helped me calm down. I read the report and instead of the kids laughing at me and making fun of me, they all stood up and clapped their hands. From that day on the kids never made fun of me any more and some actually made friends with me. I continued to be quite shy all through school but I knew if I had to stand up in front of the class, I could do it. From the passage we know that_.

Rivers are one of our most important natural resources . Many of the world's great cities are located on rivers, and almost every country has at least one river running through it that plays an important part in the lives of its people. Since the beginning of history, people have used rivers for transportation. The longest one in the United States is the Mississippi. The lifeline of Egypt is the Nile. To the people of India, the Ganges is great, but it is also important for transportation; ships can travel along it for a thousand miles. Other great rivers are the Congo in Africa and the Mekong in southeastern Asia. The greatest of all for navigation , however, is the Amazon in Brazil . It is so wide and so deep that large ships can go about two thousand miles up it. Besides transportation, rivers give food to eat, water to drink, water for crops, and chances for fun. In order to increase the supply of water for crops, engineers sometimes build a dam across a river and let a lake form behind the dam. Then people can use the water not only to irrigate their fields but also to make electricity for their homes and industries. However, large cities and industries that are located on rivers often cause problems. As the cities grow in size and industries increase in number, the water in the rivers becomes polluted with chemicals and other materials. People are learning the importance, however, of doing more to keep their rivers clean if they want to enjoy the benefits of these natural resources. Most water in rivers is polluted with _ .
Choices:
A. people's drinking water too much
B. people's swimming in the river too much
C. chemicals and other materials
D. people's building a dam across a river | C |

Different countries and different people have different manners. We must find out their customs, so that they will not think us ill-mannered. Here are some examples of the things that a well-mannered person does or does not do. If you visit a Chinese family you should knock at the door first. When the door opens, you'll not move before the host says "Come in, please." After you enter the room, you wouldn't sit down until the host asks you to take a seat. When a cup of tea is put on a tea-table before you or sent to your hand, you'll say "Thank you" and receive it with your two hands, not one hand, or they'll think you are ill-mannered. Before entering a house in Japan, it is good manners to take off your shoes.In European countries, even though shoes sometimes become very dirty, this is not done.In a Malay house, a guest never finishes the food on the table. He leaves a little to show that he has had enough. In England, a guest always finishes a drink or the food to show that he has enjoyed it. This will make the host, especially the hostess pleased. In a Malay house, a guest leaves a little food to show that _ .

mmlu | Question:
Simply, language is what people and animals use to communicate their thoughts, ideas and feelings. Of course, animals communicate with each other differently from humans, and each type of animal communicates differently. For example, a bee uses a dance to tell the rest of the bees in the hive where there is food, while whales communicate through the use of pleasant-sounding sounds. One could say then, that animals use different languages. Like animals, people also use different languages. Each culture has its own words and symbols that are used by people within that culture to communicate with others in the same culture. For example, a person living in Japan will use the Japanese language to communicate with other Japanese. Unlike animals though, some cultures use more than one language. People within these cultures are said to be either bilingual or multilingual . One such place is Canada. It is very likely that a person living in Canada may speak both French and English. Likewise, a person living in Switzerland may speak Italian, German and French. Not only do people use different languages to communicate, but languages also have different dialects. A dialect is a difference of a language which uses words and grammar somewhat differently from the standard form of the same language. For example, people who live in Manchester, England speak a dialect that is a little different from people who live in London, England; however, people in both cities speak English. There are also some people who don't use a spoken language at all. These people use their hands to communicate. This type of language is called sign language and is most commonly used by people who are deaf. Now that we know how people communicate, we are faced with a question. Are we part of a certain culture because of the language we speak, or do we speak a particular language because we are part of that culture? To put it more simply, is a Chinese person Chinese because he speaks Chinese, or does he speak Chinese because he was born in China? What part does language play in the definition of culture? The examples of bees and whales are used to show _ .
Choices:
A. animal languages are simple to learn
B. people can understand animal languages
C. different animals use different languages
D. animals communicate with each other | C |

YOUR mom might cook a bowl of noodles for you on your birthday. But in the US, a mom makes a cupcake for her children on their birthday. Cupcakes are small, round cakes topped with frosting . It has been an American tradition that moms bring cupcakes to the classroom to celebrate their child's birthday. But recently some doctors have called for this to be banned. They believe cupcakes contribute to child obesity. Despite their good intentions, however, some people believe that experts are interfering with American culture. The cupcake is seen as American as apple pie -- only prettier. According to Marion Nestle, a professor of nutrition at New York University, the cupcake is the most democratic of desserts. As they are small enough for one person, you don't have to share your cupcake with anyone -- it's all yours. They are also all the same size, so there can't be any cries of "she got the bigger piece!" Each bite can taste different depending on how much icing you have. It is a lesson in self-determination. Some people eat only a little of the frosting every time, others have it all in just one bite. In recent years, eating a cupcake has become as _ as having a cup of Starbucks coffee. Democratic presidential candidate Hillary Clinton jokingly promised on a talk show that if she was elected president, she would give everyone a cupcake on her birthday. Ruth Reichl, editor-in-chief of Gourmet magazine, explains that the rise of the cupcake is very much about going back to American national identity in food, which is all about comfort. "People want to think about when they and their country were innocent," she said. Why did the writer mention Hillary Clinton and Ruth Reichl?
Choices:
A. To arouse the readers' attention.
B. To show that cupcakes are becoming a popular to show kindness and comfort.
C. To make a comparison between them.
D. To give readers a general idea of cupcakes. | B |

One of the odd things about some business organizations is that they spend so much money attracting new customers but spend so little keeping them. It just doesn't make sense. However, taking customers for granted is a routine in some business organizations. Loyal customers are an organization's only protection against bankruptcy , and losing them because of neglect or indifference is really wrong. Not only do satisfied customers continue to buy by themselves, but they often encourage others to buy. This is advertising that doesn't cost a penny. Although there are always problems in giving good service to customers, maintaining their business isn't all that difficult. It's a matter of attitude, of believing that everyone who buys from you is entitled to the best treatment you can deliver. Plus giving just a little more than you have to. There are always problems in giving good service to customers. The reason, of course, is that no organization is perfect, and there's many a slip: unreasonable delays in filling orders, shipping the wrong goods, failing to answer letters promptly, and so on. Sometimes these errors or failures can't be helped. For example, if you can't get parts because of material shortages or a transportation strike, customers may be denied the goods they've ordered. No matter who is at fault, customers whom you value highly should generally be given the benefit of the doubt. The old saying that _ . Customers who repeatedly place large orders and pay for them will naturally, get more attention than those who buy infrequently and have to be badgered to pay what they owe. However, you have to make the assumption that all customers are good unless proved otherwise. What does the author imply by saying "all customers should be treated alike is a myth"?
Choices:
A. It's not true that all customers are treated equally
B. It is an old story that customers receive equal treatment
C. It is possible that customers should enjoy the same treatment
D. It's a rule that customers should share equal and fair rights | A |

On February 3, a Laysan albatross , a large seabird, named Wisdom, which is 62 years old, hatched a healthy chick on a Pacific island near Hawaii,. It was the sixth year in a row this bird has hatched a chick. Wisdom's species normally lives only 12 to 40 years, while she is able to hatch healthy chicks into her 60s. At breeding time, the Laysan albatross will dig out a shallow nest in the ground. The female then lays a single egg. Both she and her mate will take turns incubating the egg until it hatches. More than seven out of every 10 Laysan albatrosses' nests are on just one island -Midway Atoll. That's Wisdom's home. But her species spends most of its time in the air. In fact, biologists observe that after learning to fly, these birds may not set foot on land for the next three to five years. Albatrosses are powerful gliders , With their six-foot, nearly two-meter, wingspan, Laysan albatrosses can ride wind currents for hundreds of miles or more. Biologists now estimate that Wisdom has flown for an unusually large number of miles-between two million and three million. That is equivalent to traveling from Earth to the moon and back-four to six times! And in the months when these birds are not breeding, they stay in the air, and even sleep there. Wild albatrosses often die long before they come close to Wisdom's age. Some are eaten. Others starve, get sick or suffer life-threatening injuries from people's fishing boats. Clearly, Wisdom is special. She may have raised as many as 35 chicks in her life. Which of the following would be the best title for the text?
Choices:
A. Albatrosses-Powerful Gliders.
B. Laysan Albatrosses' Paradise-Midway Atoll.
C. Endangered Birds-Laysan Albatrosses.

Many private institutions of higher education around the country are in danger. Not all will be saved, and perhaps not all deserve to be saved. There are low-quality schools just as there are low-quality businesses. We have no duty to save them simply because they exist. But many promising institutions that deserve to continue are threatened. They are doing a fine job educationally, but they are caught in a financial squeeze, with no way to reduce rising cost or increase income significantly. Raising tuition doesn't bring in more income, for each time tuition goes up, the enrollment goes down, or the amount that must be given away in student aid goes up. Schools are bad businesses, whether public or private, not usually because of mismanagement but because of the nature of the enterprise. They lose money on every customer, and they can go bankrupt either from too few students or too many students. Even a very good college is a very bad business. It is such colleges, promising but threatened, that I worry about. Low enrollment is not their chief problem. Even with full enrollment, they may _ . Efforts to save them, and preferably to keep them private, are a national necessity. There is no basis for arguing that private schools are inherently better than public schools. There are many examples to the contrary. Anyone can name state universities and colleges that rank as the finest in the nation and the world. It is now inevitable that public institutions will be dominant, and therefore diversity is a national necessity. Diversity in the way we support schools tends to give us a healthy diversity in the forms of education. In an imperfect society such as ours, uniformity of education throughout the nation could be dangerous, In an imperfect society, diversity is a positive good. Supporters of public higher education know the importance of sustaining private higher education. According to the author's opinion schools are bad businesses because of _ .

A. mismanagement
B. too few students
C. too many students
D. the nature of schools | D |
mmlu | Question:
How men first learnt 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. These letters 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 associations---the things 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 sad events of our past; and the more we read and learn, the more the number of words that mean something to us increases. 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 convey 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 will make our speech silly and vulgar . Which is TRUE about the origin of language?
Choices:
A. Men, as well as animals, in vented certain sounds to express thoughts.
B. The origin of language is a complicated question.
C. Words did not haven written form, at first.
D. Words were invented to represent meanings. | C |

mmlu | Question:
Can we turn negative thoughts like "I never do anything right" into positive ones like "I can succeed"? Is there power in positive thinking? Researchers in Canada just published a study in the journal Psychological Science that says trying to get people to think more positively can actually have the opposite effect: it can simply emphasize how unhappy they are. The study's authors, Joanne Wood and John Lee of the University of Waterloo and Elaine Perunovic of the University of New Brunswick, begin by referring to older research showing that when people get feedback which they believe is overly positive, they actually feel worse, not better.If you tell your friend that he may be an Einstein, _ In one 1990s experiment, a team including psychologist Joel Cooper of Princeton asked participants to write passages opposing funding for the disabled.When they were later praised for their sympathy, they felt even worse about what they had written. In this experiment, Wood, Lee and Perunovic measured 68 students' self-esteem .The participants were then asked to write down their thoughts and feelings for four minutes.Every 15 seconds, one group of students heard a bell.When it rang, they were supposed to tell themselves, "I am lovable." Those with low self-esteem didn't feel better after the experiment.In fact, their moods turned significantly darker than those of members of the control group, who weren't urged to think positive thoughts. The paper provides support for newer forms of psychotherapy that urge people to accept their negative thoughts and feelings rather than fight them.In the fighting, we not only often fail but can make things worse.Meditation techniques, on the contrary, can teach people to put their shortcomings into a large, more realistic perspective .Call it the power of negative thinking. What do we learn from the experiment of Wood, Lee and Perunovic?
Choices:
A. It is important for people to continually improve their self-esteem.
B. Thinking positively can bring a positive change to one's mood.
C. People with low self-esteem seldom write down their true feelings.
D. Forcing a person to think positive thoughts may lower their self-esteem. | D |

Last year, my boyfriend suggested that I should run the London marathon, and I laughed. He laughed too, but he laughed too long and too loud. That made me think. I realized that he didn't believe that I could do it. That made me angry, and determined. Now he knows that I can! Training wasn't easy, but I kept going. I didn't need special training but I did need to buy very good shoes. Each day, I went a little further. By the end of three months, I was running five days a week. Sometimes in the evenings I ran 10 km; on Sunday mornings, I sometimes ran about 30 km. I used to come home, have a shower and eat my breakfast. I felt wonderful! On the day of the race in London, I lined up with about 30,000 other runners. The faster runners were at the front, while slower runners like me were placed further back. In that way, the professional runners and club runners were not slowed down by the amateurs. At first, there were so many runners close together that we were almost falling over each other. We could only run very slowly but that was a good thing because it meant that we didn't rush off too quickly. Gradually the runners spread out and there was more space. There were thousands of people watching us along the route and they cheered and clapped everyone, even the slowest runner. It was wonderful! For the first 10 km I felt very happy and my legs felt very comfortable. However, at 15 km I got a pain in my side and running became difficult, but I kept going and the pain disappeared. At the 30 km mark, I felt extremely tired, and wanted to stop, but I kept on going. I covered another 3 km and then I began to feel better again. By the time I reached the 35 km mark, I knew I was going to get to the end of the course. Somehow that confidence made me feel lighter and faster and it seemed as if my legs flew over the last few kilometers. I passed hundreds of slower runners, some of whom had passed me earlier, and I felt wonderful! As I came round the last bend and saw the finishing line, I could see three runners ahead of me. I raced past all of them to finish the race in just under four hours. The winner had completed the race in 2 hours and 10 minutes, but I didn't care! I had run 42 km and completed my first marathon! When the race began _ .

mmlu | Question:
There are two kinds of people in the world. Those of the first kind are born idlers , taking interest in nothing. It seems what they live for is to pass time idly. They simply don't know why they have to do so, nor will they bother to ask. The other kind are those who take things seriously and never wish to idle away their life. But only a part of the second group are eager enough to make success. All the others fail to make enough effort to make their dreams come true. Why do things so happen to them? What are the reasons? I later find out that some people are determined. They are "igniters" that catch fire of their own, giving light and heat. But that's not the case with others. They may be fuels but not igniters. As pieces of wood or coal, they need a match or a lighter to make them burn so that their energy can be released to give off light and heat. The majority of people need some igniter to light them. Thus igniter becomes a must for those people to succeed. Unless a suitable igniter comes their way, they will always remain idle like cold unused firewood or coal. Fortunately, such an igniter is not difficult to meet. One may find it in an instructive book, a film story, a few words of a close friend, some advice of a good teacher, a pleasant journey, or an unexpected love. Any of these, coming at the right time, can serve as an igniter to start one's enthusiasm for learning or for a better career, to turn him from a passive state of waiting to an active state of pursuing, to lend him strength to go ahead bravely. In that case, what he has prepared for years will be quickly turned into fruitful reality. Such an igniter may turn up of itself, but most likely we have to find it ourselves. Never let a chance slide away, for it is the key to your success. According to the writer, what do most people definitely need to succeed?
Choices:
A. Storing a lot of energy.
B. Great interest in everything.
C. An igniter coming at the right time.
D. Wonderful dreams about a bright future. | C |

Are you carrying too much on your back to school? I'm sure lots of your age will say "Yes". Not only the students in China have this problem, but children in the United States also have heavy school bags. Doctors are starting to worry about that younger and younger students are having problems as a result of school bags being too heavy for them. "It's hard for me to go upstairs with my bag because it's so heavy," said Rich Hammond, an 11-year-old student in the US. Rich is among students who have common school bags with two straps to carry them, but many other choose rolling bags. But even with rolling bags, getting up stairs and houses is still a problem for children. Many of them have hurt backs and necks because of the heavy school bags. But how much is too much? Doctors say students should carry no more than 10% to 15% of their own body weight. Scott Bautch, a black doctor, said children under Grade 4 should stay with 10%. But it is also important that older children don't stay with over 15%, because their bodies are still growing. "Children are losing their balance and falling down with their school bags," he said. Parents and teachers are starting to tell children to only take home library books that they will be reading at night. Some teachers are using pieces of paper or thin workbooks for students to take home. One of the best answers is, as some children said, to have no homework at all. If a child carries a heavy school bag, _ .

A. his back and neck will be hurt
B. his head and arms will be hurt

Speaking two languages can actually help offset some effects of aging on the brain, a new study has found. Researchers tested how long it took participants to switch from one cognitive task to another, something that's known to take longer for older adults, said lead researcher, Brian Gold, a neuroscientist at the University of Kentucky. Gold's team compared task-switching speeds for younger and older adults, knowing they would find slower speeds in the older population because of previous studies. However, they found that older adults who spoke two languages were able to switch mental activities faster than those didn't . The study only looked at life-long bilinguals, defined in study as people who had spoken a second language daily since they were at least 10 years old. Gold and his team asked 30 people, either bilingual or monolingual , to have a series of tests. They found that bilingual people were not only able to switch tasks faster, they had different brain activity than their monolingual peers. Kristina called bilingualism "a beautiful natural experiment", because people grow up speaking two languages,and studies have shown that they get certain cognitive benefits from switching between languages and determining which to respond with based on what's going on around them. Gold said he grew up in Montreal, where he spoke French at school and English at home, prompting relatives to question whether his French language immersion would somehow hinder his ability to learn English. "Until very recently, learning a second language in childhood was thought of as dangerous," he said. "Actually, it's beneficial. " What's the main idea of the passage?
Choices:
A. Researchers found that speaking two languages is important.
B. Researchers found that bilingual people respond slowly.
C. Researchers found that bilingual people can slow down the speed or aging on the brain and respond fast.
D. Researchers found that bilingual people are great. | C |
mmlu | Question:
Today, I'm going to talk about the invention of the camera and photography. The camera is often thought to be a modern invention. But as early as 1727, a German physicist discovered that light darkened silver salt, a chemical compound. Using as a camera, a big box with a small hole to let the light in, he made temporary images on the salt. Silver salt is still the base of film today. Then a French scientist made the first permanent picture by using a special piece of metal sensitized(...)with silver salt. A photograph he made in 1826 still exists. The painter Daguerre improved on the process by placing common salt, the kind we eat, on the metal. This was in 1839, the official date of the beginning of photography. But the problem was the printing of the photographs. And it was not until other scientists developed the kind of paper we now use that good printing was possible and photography became truly common. In the 1860s, Mathew Brady was able to take his famous pictures of the American Civil War, thus making portrait poses very popular. In the 20thcentury, George Eastmen of theprefix = st1 /United Statessimplified film-developing film, and Dr. Edwin Land invented the so-called instant camera with self-developing film. If we say that the photography came into existence in 1839, it follows that it has taken more than one hundred years for the camera to reach the present condition of technical refinement . What does the writer regard as the official date of the beginning of photography?

A. The use of common salt in the process of making pictures.
B. The first permanent picture made by a French scientist.

Two men were sitting together on a ship. They were on a long travel. One of them was a professor. The other was a farmer. They sat without talking for a while, and then the farmer said, "Let's do something to pass the time." "What do you want to do?" the professor asked. "We can ask each other riddles." The farmer said, "You start." "Let's make the rules first," the professor said. "That's not fair. You are a professor with much knowledge. You know more things than I do. I am just a farmer." "That's true." The professor said. "What do you want we should do?" "If you don't know the answer to a riddle, you pay me $100. And if I don't know the answer, I'll pay you $50." The farmer said.

There are some very good inventions which, for one reason or another, don't become popular. These inventions should be better known, even though I think that some of them are crazy. Let's have a look at some of these inventions and see if you agree that they should be more successful. The Australians had a great idea to stop people from drinking and driving. The idea was that if a driver wanted to start the car, she or he would have to blow into a bag first. If there was too much alcohol in their breath, the car wouldn't start. It sounded like a great idea to me, but people said that they might need to drive the car in an emergency even if they had drunk too much alcohol. Another idea I liked was an invention by a scientist who thought his children watched too much TV. He connected the TV to an exercise bike so that the electricity to power the TV was produced by the bike. If the children wanted to watch a lot of TV, they had to pedal very hard. I found another invention on the Internet which encouraged good habits. Believe it or not, this invention was an ashtray which spoke to you when you lit a cigarette! The "voice" of the ashtray was started by the heat from the cigarette and reminded you how dangerous it is to smoke. One of the strangest inventions I have come across is a bicycle which can cross rivers! The idea was that when you came to a river, you could _ a huge plastic ball all around the bike. You would then get into the ball which would float on the river while you pedaled the bike inside the ball! Why not use a bridge instead? A friend of mine at school once bought a strange pair of football shoes. On the bottom of the shoes there was a rotating pad of studs . The idea was that you would change direction more quickly if the studs rotated with you. The problem was that every time you stopped you changed direction whether you wanted to or not! I think he wore those shoes twice! One thing I would like is a baseball cap with a built-in radio so you can listen to sport all day with your hands free. While we are on the subject of sport, the Americans invented a kind of robot for sports fans. If you were watching your team on TV on your own, you could press a button and the robot would do "high fives" with you! Fantastic! I wonder if you have any good ideas for inventions like these. What can we know from the passage?
Choices:
A. The father used his invention to stop children watching too much TV.

mmlu | Question:
Once upon a time, science fiction was just a style among other styles. There were crime stories, there were horror stories, there was literary fiction-and there was science fiction. But today science themes dominate these other styles. It's difficult to think of much modern crime, horror or "serious" fiction that doesn't involve science. And it's not just books. With every second movie and computer game having a sci-fi element, science fiction seems to have controlled our entire entertainment culture. It's clear that if we want to define science fiction we should relate it to the role that science plays in our lives. Perhaps the place to start is by noting when it began. Although some experts have claimed to be able to trace sci-fi back to ancient times, it is more plausible to find it in initial form in the 19th century, when industrial societies arose. One of the features that set industrial societies apart from other kinds was the increasing part that science played in everyday life. Factories with vast machines turned out huge quantities of goods, which were transported by trains, motor vehicles and ships all over the world. Cities were built on the back of technology, with electricity in homes and hospitals helping everyone to lead healthier, more convenient lives. All of these changes had great effects not only on people's real lives, but on their imaginative ones. Writers began to articulate these changing physical and mental landscapes, eventually giving science fiction a large and devoted fan base of especially young readers, who found that it spoke to their curiosity about the future that science would create. But sci-fi reflected fears about science more than it did hopes. These typical early science fiction novel might be a UK novel like H.G. Wells' The War of the Worlds (1897). With great skill, Wells played upon the fears of technology by imagining Earth under threat by a civilization -that of men from Mars. The science fiction of today expresses the impact of the computing revolution, robotics and our environmental challenges, while it is less concerned with "little green men from Mars" and other themes of past sci-fi. Given that science, technology and politics are always intertwined , contemporary science fiction often has a great deal to say about power. Many recent novels - like American Cory Doctorow's Little Brother (2008) - are concerned with government and security service "conspiracies " against the people, particularly as the revelations of whistleblowers like Edward Snowden sink in. This can give sci-fi writing a "skeptical" feel. This underlines one of the features that remains constant between the beginnings of the empire of science fiction and its state today. As then, so now: We want to read about how fearful the future will be, not how it will be a paradise . What is mostly conveyed in contemporary science fiction?
Choices:
A. Our earth is threatened by aliens from Mars.
B. Modern crime and horror are involved in science.
C. Power is a very important element to ensure security.
D. Entertainment culture and environmental issues are crucial. | C |

An eight-year-old child heard her parents talking about her little brother. All she knew was that he was very sick and they had no money. Only a very expensive operation could save him now and there was no one to lend them the money. When she heard her daddy say to her tearful mother, "Only a miracle can save him now," the little girl went to her bedroom and pulled her money from its hiding place and counted it carefully. She ran to a drugstore with the money in her hand. "And what do you want?" asked the salesman. "It's for my little brother," the girl answered. "He's really, really sick and I want to buy a miracle." "Pardon?" said the salesman. "My brother Andrew has something bad growing inside his head and my daddy says only a miracle can save him. So how much does a miracle cost?" "We don't sell a miracle here, child. I'm sorry," the salesman said with a smile. "Listen, if it isn't enough, I can try and get some more. Just tell me how much it costs." A well-dressed man heard it and asked, "What kind of a miracle does your brother need?" "I don't know," she answered with her eyes full of tears. "He's really sick and mum says he needs an operation.

mmlu | Question:
Alone in the wilderness. Nothing but jungle. A world of shadow with the rays of light falling like blonde hair from the crowns of the giant trees. Jungle in the midday sun. Everything motionless. Not a sound from sky or earth. Complete silence. Only some coconuts falling, at long intervals, very far away. The world reduced to the soft touch of cool grass along my naked back, and a sweet smell of rich soil and vegetation. Stretched out with closed eyes beside my heavy burden of fruit and firewood, I enjoyed the feeling of fresh blood streaming through every part of my body and fresh jungle air filling every corner of my lungs. Resting motionless, I could see the sun through my closed eyelids, alone in the sky, as lonely as I, and as motionless and silent as everything else. The earth had surely stopped turning and somewhere on this planet there was supposed to be roaring traffic in busy streets. What a crazy, unbelievable thought! Another coconut fell, to make the world come to a complete standstill. I had to roll over onto my stomach to feel that at least I could move and make noises. Then I found company. A little brown ant was struggling to find its way with a bit of dry straw through the jungle of leaves and grass below my nose. I wondered if I could give the little fellow a lift with its burden, but it showed not the slightest sign of tiredness and struggled on with all six legs, head first or head last, waving its feelers energetically as if the trip had just started. Who ever saw a tired ant? Tiredness, disagreeable tiredness, is restricted to hunted animals, slaves and modern man. It is as great an effort for an office clerk to walk five blocks with a loaded brief-case as it is for a jungle-dweller to cross a valley with a goat on his back. It is as hard to get up and climb or run when you have been seated for years as it is to get up and walk when you have been in bed for months. The body is strange. Spare it, and you get really tired for almost nothing; use it, and almost nothing makes you really tired. I rose to my feet. I had heard a horse neighing down in the valley. Above me, on the open highland plains, there were wild horses. But down in the valley there was never a horse unless there was a man on it. Somebody was making his way up the valley and my wife was alone. How does the author feel about the ant?
Choices:
A. He admired its attitude toward work.
B. He was amazed at its tireless efforts.
C. He showed sympathy for the little ant.
D. He was content to have it as a companion. | A |

mmlu | Question:
Not long ago, the only time you could see a robot was when you were reading a novel or watching a movie such asStar Wars . Today, however, a lot of things in science stories have been science facts. Robots are starting to appear in our everyday lives. These robots have different sizes, shapes, and colors. But they all have the same type of man-made "brain". Leading the robot revolution are industrial robots that work in factories. Industrial robots can do different kinds of jobs that are often boring and sometimes dangerous. Robots are also coming to American homes, though not as quickly as they are entering factories. These robots aren't as friendly and bright as those you saw in Star Wars.But, their makers say, today's home robots "walk", sense objects in their way (and sometimes knock into them), and even carry objects (which they sometimes drop). Well, nobody is perfect. We may laugh at home robot today, but some day they may see and hear better than humans do. We humans can only see certain wavelengths of light, and hear certain sounds. That's because the abilities of our eyes and ears are limited. Robots, however, need not have the same limits as we have. Robot may also be equipped with devices that pick up information humans can't. To understand what their sensing devices pick up is a hard job. Remember, man--made brains handle information, including all kinds of data, as zeroes and ones. Imagine the difficulty in trying to explain to a robot what a football looks like--using only zeroes and ones. The development of robots suggests that _ .
Choices:
A. science and technology are developing fast
B. people are interested in new inventions
C. machines are more capable than humans
D. robots can be very interesting | A |
mmlu | Question:
Experts estimate that one out of every five fish sold was caught illegally. It threatens food security and hurts the environment. Officials are using new observational technology to fight illegal fishing. "Thank you for taking the time to join us here in Harwell (UK) in the Operations Center to what we call 'Project Eyes on the Seas.'" says Tony Long, who leads the Ending Illegal Fishing program for Pew Charitable Trusts. The group created Project Eyes on the Seas. Large three-dimensional images of a globe can be seen on a video. "It looks different from what you might expect because this globe only shows you the boats that are coming into this system from a live automated information system or AIS." The screen shows 120,000 fishing boats have AIS. They are required to have the technology. But those who are fishing illegally often turn it off. The technology does not tell observers when that happens. Project Eyes on the Seas combines satellite information with secret government records on every ship's past activities. Mr. Long says that permits researchers to understand exactly where the fishing boats are operating. The Pew team gives the information it gathers to port officials to help them decide if they should take action against a ship. Tony Long says he would like to be able to provide port officials all over the world with clear lists. They would inform the officials about ships to inspect, ships to bar from entrance, and ships to permit entrance for trade activities. The Pacific island nation of Palau was an early user of the technology. Palau has one of the richest fishing areas in the world. Last year, it announced a plan to ban commercial fishing in a 630,000 square kilometer area. K.B. Sakuma is a special adviser to the president of Palau. He says Palau is trying to deal with a recent increase in illegal, unsupervised and unreported fishing. "And it's come to a head in the last year or two. From our southern island in the evening you can see on the horizon just dotted lights of these illegal fishermen that come into our waters, fill their ships with our fish, our resources, our food security..." According to the estimation, what is the percentage of illegal fishing?
Choices:
A. 1%
B. 5%
C. 23.5%
D. 20% | D |
