mmlu | Question:
Everyone has got two personalities-the one that is shown to the world and the other that is secret and real. You don't show your secret personality when you're awake because you can control your behavior, but when you're asleep, your sleeping position shows the real you. In a normal night, of course, people frequently change their positions. The important position is the one that you go to sleep in. If you go to sleep on your back, you're a very open person. You normally trust people and you are easily influenced by fashion or new ideas. You don't like to displease people. So you never express your real feelings. You're quite shy and you aren't quite sure of yourself. If you sleep on your stomach, you are a rather secretive person. You worry a lot and you're always easily upset. You always stick to your own opinions or judgment, but you don't raise your hopes too much. You usually live for today not tomorrow. This means that you enjoy having a good time. If you sleep curled up, you are probably a very nervous person. You have a low opinion of yourself and so you're often defensive. You're shy and you don't normally like meeting people. You prefer to be on your own. You're easily hurt. If you sleep on your side, you have usually got a well--balanced personality. You know your strengths and weakness. You're usually careful. You believe in yourself. You sometimes feel anxious, but you don't often get sad. You always insist on what you think even if it makes people rather angry. According to the passage, a person, who is not willing to change his mind and hard to deal with, probably sleeps _ .
Choices:
A. on his side
B. on his back
C. curled up
D. on his stomach | A |
mmlu | Question:
The majority of Indian women wear a red dot between their eyebrows. While it is generally taken as an indicator of their marital status, the practice is primarily related to the Hindu religion. The dot goes by different names in different Hindi dialects, and "bindi" is the one that is most commonly known. Traditionally, the dot carries no gender restriction: Men as well as women wear it. However, the tradition of men wearing it has faded in recent times, so nowadays we see a lot more women than men wearing one. The position of the bindi is standard: center of the forehead, close to the eyebrows. It represents a third, or inner eye. Hindu tradition holds that all people have three eyes: The two outer ones are used for seeing the outside world, and the third one is there to focus inward toward God. As such, the dot serves as a constant reminder to keep God in the front of a believer's thoughts. Red is the traditional color of the dot. It is said that in ancient times a man would place a drop of blood between his wife's eyes to seal their marriage. According to Hindu beliefs, the color red is believed to bring good fortune to the married couple. Today, people go with different colors depending upon their preferences. Women often wear dots that match the color of their clothes. Decorative or sticker bindis come in all sizes, colors and variations, and can be worn by young and old, married and unmarried people alike. Wearing a bindi has become more of a fashion statement than a religious custom. Why did people in India start wearing a red dot on their forehead?
Choices:
A. To indicate their social rank.
B. To show their financial status.
C. To show their religious belief.
D. To highlight their family background. | C |

Opera |BooingattheRoyalOperaHouse Audience love to make a noise. They will cough, laugh or clap. Disrupting an event satisfies our sense of narcissism . The booing of a violent scene in the Royal Opera House's new production ofGuillaumeTellmay have been justified, but it set a bad beginning.

mmlu | Question:
Every year, British newspapers report on the stranger questions asked in Oxbridge (Oxford & Cambridge) interviews. Often, though, these questions are not as strange as they first seem. And they are all designed to give applicants a chance to think. Arriving for her first Oxford interview, my sister Jen saw that there was only one chair in the waiting room. On the chair was a large fork. Jen had heard about the strange things in Oxbridge interviews, and believed that this was a test. "What if they're watching me?" she thought. "If I move the fork, it will show initiative ; if I don't move it, it will show that I can easily fit into new situations." In the end, she sat uncomfortably on the edge of the chair! Applicants must be prepared for the unexpected. Now it was Jen's turn. She was handed a monkey skull and asked to talk about it. At first, this seemed unfair --- what could she say? But she soon calmed down, started thinking, and found that there was plenty to talk about. Oxbridge interviews are designed to find out how you think, not just what you think. And there are no wrong answers. Jen learnt that, and she passed the interview. What advice does she give? " Don't be nervous, and be prepared for the unexpected!" Jen learned that it was very important to _ in order to pass the Oxbridge interviews.
Choices:
A. make up new situation
B. show how one thinks
C. describe what one hears
D. talk about various monkeys | B |
mmlu | Question:
One of the biggest challenges facing students and their families is what career they should enter and what is the best path for them to take. I was talking to someone the other day who told me he first studied accounting because that was what everyone was studying several years ago. It was and some say still is a reliable career. However, then he told me that he was now studying financial investment because again--- that's what everyone was studying now and it was needed if he wanted to get ahead in the company. And I asked him what he was actually interested in and then-- well the conversation kind of died. So I asked why he had bothered studying accounting in the first place and he explained that it was his parents' idea. Finally I asked what his passion was and he wasn't too sure because he never thought about it. And so it is-- lifelong learning-- or the continual need to make ourselves marketable in a world that appears to be more competitive as time goes by. Is there a secret to help us so we can live a life of quality? Regardless or not at this stage in world history with increasing connection between people, ideas and markets -- the ability to match the needs and desires of the day with your own skills and products is a tremendous and vigorous challenge. Many have gone into English or foreign language study because it was encouraged at the time when China was entering the WTO. Or maybe they were interested in international affairs or working abroad. Upon graduation they then faced the reality that there was a limit to how many jobs they could apply for. Perhaps some then studied further doing courses for work such as a tour guide or translator/ interpreter. Many may have decided that going into teaching was more rewarding or stable. Others would have gone into media or advertising or conference management and acquired new skills along the way. This constant quest to remain ahead of the game makes many upset and exhausted. Some futurists who examine technology have even predicted that people should expect to change careers six or seven times during their lifetime! So if you are concerned by the nature of change, why not start spending more time looking at the most modern leading economies, institutions and their publications. A whole lot of changes are starting to happen yet there is no reason why this cannot be enjoyable, exciting and also rewarding. Our attitude, approach and willingness to continually learn and update our skills must remain strong. My tip is to track the work that our government is setting about to achieve. In particular, look at the people who have been chosen as the key support team and try to read behind the light surface news and look at their career development and examine the recent reports that they are now recommending the government move towards. Key industry development, new ways of dealing with information and new demands are creating opportunities for the students and workers of tomorrow -- if we stay prepared. In the writer's opinion, to make yourself competitive in the changing world today is _ .
Choices:
A. exhausting
B. disappointing
C. unbelievable
D. necessary | D |

mmlu | Question:
I could fill a book with embarrassing situations I've been in over the years. These moments used to haunt me and my face would turn as red as a big tomato. It wasn't until I was in my late teens, working at a hotel that things changed for me. I took a year off in between high school and university, because like many people my age I had ly no idea what I wanted to do, and I didn't want to waste $ 5,000 on a university tuition . I tried to keep silent at my new job, avoiding the other employees. All of them didn't care about me except for one girl. She kept at me, telling me stories of her weekend and how she loved snowboarding, something I was interested in as well. She was the type of warm personality where people were immediately drawn to her, and soon enough I found myself looking forward to our coffee breaks and snowboarding after work. The more I hung out with her, the more I realized that this girl, who seemed to have it all together, was in fact just like me, except for one major difference. She laughed at herself. One night after work we were snowboarding and she fell down carelessly resulting in a mouth full of snow. Instead of getting embarrassed she jumped right up laughing loudly at how ridiculous she must have looked. As time went on, her warm personality began to wear off on me and soon enough I had a mini-breakthrough. I'm not saying that I no longer find myself in embarrassing situations; I've just learned how to handle them differently. Just a few months ago I walked out of a bathroom unaware of the fact that my skirt was tucked in my underwear. But instead of rushing back to the bathroom I calmly pulled it out and continued on my way shaking my head and smiling. When she fell down carelessly resulting in a mouth full of snow, the girl _ .
Choices:
A. just laughed and joked about herself
B. tried to hide her pain through laughing
C. was quite upset and didn't know what to do
D. couldn't help becoming excited | A |
mmlu | Question:
Vacation is a time for refreshment. In work, we are often called to think. Sometimes, it's good to give our brains a rest. Without a break, we may not be able to perform up to our potential. This can be a problem, not only for the employee, but for the employer as well. "The main benefit of vacation is for the worker to come back energized," says Weaver. "If they haven't had a break, then they're not coming back with new energy. They haven't had a chance to step back and get perspective , and come back with renewed enthusiasm." Long working hours without a break, insecurity about one's job, and other work-related worries can lead to burnout and stress. Humans can usually adapt to pressure, but not for a limitless amount of time. "It is a problem of relating good workers and having them loyal to the firm while they're _ ," says David Maume, PhD, professor of sociology at the University of Cincinnati. He says burnout can also affect employees' productivity, creativity, and effectiveness. In addition, high levels of stress are likely to be precursors to depression, which can hit both the employer and employee's pocketbook. Even people who manage to remain productive at work can have problems. If they're always at work, then they're not with their family and friends. If they're working while on vacation, for the time that they're on the job, they're not really present. An unbalanced emphasis on work can strain family and social life. When you come up for air, you may see that you're alone, or that your relationships have gone on without you. Which of the following is the best title for the passage?
Choices:
A. Why Workers Need Vacation
B. Why Workers Need New Energy
C. How to Deal with Daily Pressure
D. How to Spend Vacation Effectively | A |

mmlu | Question:
It came with devastating force,a natural disaster of strange intensity that shocked the world and killed tens of thousands.The waters have now receded,but disease and food and water shortages trouble a number of countries around the Indian Ocean.Millions of survivors face serious problems. The number of survivors in need of food aid after the Indian Ocean disaster has climbed to 5 million people.They stretch from Somalia to Thailand,and the figure could rise further,the United Nations has said. Relief teams hope to reach all of the estimated 700 000 hungry in Sri Lanka within three more days.It could take longer before enough food aid gets to the nearly 1 million people in need in hard-to-reach parts of Indonesia.Another serious problem is the need for purified water. Although aid had poured in from all over the world to the disaster areas,"Logistics is the big problem here--just getting the stuff out to people who need it,"said Ron Libby,emergency management specialist at the USA agency for International Development. Relief efforts are hindered by the difficulty of delivering aid to the more than 1000 islands scattered across hundreds of kilometers of ocean. For those who survived the tsunami's force,disease is now the No.1 problem.Five million people are short of water,food and basic sanitation across the region.World Health Organization(WHO) crisis chief David Navarro said 50 000 more people could die from disease and other causes,as has been the case in previous humanitarian emergencies. WHO said it had already received a handful of reports of malaria and dengue fever and hundreds of reports of diarrhea and infected wounds.It said millions of water purification tablets had been sent to Asia,along with sanitation engineers to rebuild water sanitation infrastructure. Psychologists are warning that mental health problems caused by the tsunami could prove harder to resolve than the physical damage. Some survivors say they are plagued by recurring nightmares about walls of water.Many locals are afraid to return to beachside homes.Officials also warn that suicide rates could rise dramatically as parents struggle with guilt at losing children. Psychologists estimate that 20 to 30 per cent of people who face traumatic events eventually develop symptoms,such as alcohol abuse,lack of concentration at work and an inability to develop close relationships. Although the Thai Government has offered to build temporary beachside housing,many refugee families are refusing to come down from the hills.Others are afraid to go back to jobs on the sea. Over 150 000 people were killed by the tsunami,but hundreds and thousands more have been left with no means to earn a living. In the village of Akirapettai in India,all that is left is the twisted wreckage of the fishing fleet.Dakshina Murti,a fisherman,not only lost three family members,but also lost his boats,his nets,everything. "Everything's gone,"he says.With no government aid so far,all he has is a wreck.There are several million people who suffered the same experience.Homes have been destroyed,as well as wharves,docks,and sheds. For now,rebuilding the economy remains a distant concept. This passage is mainly about _ that happened around the Indian Oceans.
Choices:
A. the causes of the tsunami
B. the result after the tsunami
C. the sign of the tsunami
D. the warning of the tsunami | B |

mmlu | Question:
"Food in France is still primarily about pleasure,"says Mark Singer, technical director of cuisine at Le Cordon Bleu in Paris."Cooking and eating are both pastimes and pleasure."The French might start their day with bread, butter, jam, and perhaps something hot to drink -- it's a time of the day when the whole family can be united. Singer, born in Philadelphia, has lived in France for more than 40 years. "Although things have changed greatly in the past 20 years when it comes to food in the country,"he says,"and what was a big affair with eating has been slowly softened up, there are still events in the year, like birthdays and New Year's Eve and Christmas Eve that are still really anchored in traditional food and cooking. But it's not every day." Some people think French food life may be a performance, adds Jennifer Berg, director of graduate food studies at New York University."They want to believe that France is this nation where people are spending five hours a day going to 12 different markets to get their food. The reality is most croissants are factory-made, and most people are buying convenience food, except for the very small group of people in high society. But part of our identity relies on believing that myth." In Italy, as in France, takeout is still ly rare."Eating fast is not at all part of our culture,"says Marco Bolasco, editorial director of Slow Food and an Italian food expert. Our meals are relaxed, even during a lunch break. Food in Italy is love, and nutrition, and pleasure, he says. An Italian child's first experience with food is not small round cakes or rice or eggs, but probably ice cream, notes Bolasco. Status and wealth play less of a role in food. How have things about French food changed?
Choices:
A. People prefer to cook at home.
B. More people choose to eat out.
C. Traditional food is less frequently cooked.
D. People eat faster than before. | C |

mmlu | Question:
"Linda, if beating yourself up were an Olympic sport, you'd win a gold medal!" Annabel, my close friend, stunned(...)me with that frank observation after I told her how I had mishandled a situation with a student in a third-grade class where I was substituting . "I should never have let him go to the boy's room without a pass! It was my fault he got into trouble with the hall monitor! I'm so stupid!" My friend burst out laughing, and then made her "Olympic" comment. After a brief period of reflection I had to admit that she was right. I did put myself down an awful lot. Why, just during the previous day I had called myself "a slob" for having some papers spread out on my desk, "ugly" when I left the house without makeup and "an idiot" when I left the house for an emergency substitute job without my emergency lesson plan. In a more reflective tone, Annabel said, "I once took a workshop at church where the woman in charge had us list all the mean things we say about ourselves." "How many did you have on your list?" I asked. "Fifteen," she confessed. "But then the teacher said, 'Now turn to the person next to you and say all the items on your list as if you were speaking to that person!' " My jaw dropped,"What did you do?" "Nothing. Nobody did. We all just sat there, until I said, 'I could never say these things to anyone else!' " "And our teacher replied, 'Well, if you can't say them to anyone else, then don't ever say them to yourself!' " My friend had a point. I would never insult a child of God---and I'm God's child, too! God, today let me be as kind to myself as I would be to another of Your children. What can we learn about Annabel?
Choices:
A. She used to put herself down a lot.
B. She often goes to church.
C. She was in charge of a workshop.

mmlu | Question:
Why do earthquakes happen? Scientists explain that the outside of the earth is made of a number of different plates . For example, at San Francisco the Pacific Plate which is moving towards the northwest meets the North American Plate. The Pacific Plate is moving very slowly-at 5. 3 centimetres a year. Sometimes these two plates stop and do not move for years. Then suddenly, they jump and an earthquake is felt. As the movement of these plates, West America near the sea has always been a bad place for earthquakes. When the 1906 earthquake happened, the Pacific Plate jumped 5-6 metres to the north. We cannot stop earthquakes, but we can do things to make sure they don't destroy the whole of cities. First ,it is not a good idea to build houses along the lines, where two of the earth's plates join together. Second, if you think there may be an earthquake, it is better to build houses on rock not on sand. Third, you must make the houses as strong as possible. Weak buildings will fall down in an earthquake, but strong ones may stay up. We can't stop _ .

B. earthquakes

Our sun is a star, and nine worlds move round it. Worlds like these are planets . But there are other stars, other suns. Not only thousands of them, but millions of them. Do different stars have planets? We can see the planets round our own sun. But we haven't seen any more. The stars are too far away from us. Stars give out light, but the planets don't have any light of their own. So we can't see them. They're too far, and too dark. Still, we can tell that some stars have planets. While a big planet goes round, it pulls its star to one side. And sometimes we can see this, Then we know that the star has a planet. For example, Barnard's Star is a small red star. And it is the quickest star in the universe. But sometimes it moves slower, and then quicker again. We have know Barnard's Star for many years, and now we are sure it has a planet. Which of the following is not true?

Busy as I am every day, I always open my computer and check my email. Most of the time I am simply doing finger exercises, another form of piano practice without beautiful tones. Sometimes, however, I receive a gift, reminding me of the gifts in my life. The following passage is one of those gifts. Peter Jones is a 92-year-old, short, calm and proud man. Every morning he is fully dressed by eight o'clock, with his hair fashionably combed and face perfectly shaved even though hi is unable to see anything. He would move to a nursing home today. His wife of 70 years old has recently passed away, making the move necessary. After hours of waiting patiently in the entrance hall of the nursing home, he smiled sweetly when told his room was ready. As he moved his walking stick skillfully to the elevator, the nurse provided a visual description of his tiny room. "I love it," he stated with enthusiasm. "Mr. Jones, you haven't been the room," said the nurse. "That doesn't have anything to do with it," he replied. "Happiness is something you decide on ahead of time. Whether I like my room or not doesn't depend on how the furniture is arranged...it's how I arrange my mind. I have already decided to love _ It's a decision I make every morning when I wake up. I have a choice: I can spend the day in bed complaining of the difficulty I have with the parts of my body that no longer work, or get out of bed and be thankful for the ones that do." Each day is a gift, and as long as we are alive. We'll focus on the new day and all the happy memories we've stored just as Mr. Jones does. What do we know about Mr. Jones ?

If you are sitting down listening to what I'm going to say, stand up. Move your legs. Touch your toes, if you can. Do anything but sit. If you cut down on the time you spend sitting, you might live longer. New research shows that sitting less than three hours a day might extend your life by two years. Just the opposite, says Peter Katzmarzyk. He is a scientist at the University of Louisiana in the southern United States. He says that sitting is _ in our lives. "We sit while we're eating; we sit in the car; we sit while we watch TV. Many of us sit for many hours at work. " But, he adds, that does not make sitting good for us. The human body is designed to move. But modern lifestyles and office jobs rarely give us the chance to move around. Exercise is important. So is not sitting. "We can't throw away physical activity. It's extremely important. We have 60 years of research showing us that. Even if you exercise for 30 minutes a day, what goes on in the other 23-and-a-half hours a day is also very important." Mr. Katzmarzyk and his co-workers are part of a new generation of researchers studying how sitting all day affects length of life. This is a relatively new area of study--studies that have assessed the relationship between sitting and mortality or television viewing and mortality. Making uses of the few studies available to them, they found that cutting television time to less than two hours a day could add one-point four years to life. New desk designs are helping Change is already coming to some offices, especially in the design of desks. A "standing desk" lets people stand while they work. Another new design is called the "treadmill desk." A treadmill is an exercise machine that lets you walk in one place. That's one of the strategies that many companies are using now. Some companies may equip their employees with a "standing desk" or a "treadmill desk". Other companies may not buy one for everybody, but they'll have a bank of these desks where people can go for an hour a day and answer their emails or talk on the phone. Even some U.S. schools are beginning to experiment with such desks to keep children moving. Mr. Katzmarzyk says studying this problem has inspired his team to make a few changes in their own lives. "As a university professor, you know, it is a very sedentary occupation. We're chained to a desk in terms of writing papers and doing research. We really try to limit the amount of time we spend doing that." Suggestions for sitting less If you work in office job or have a sedentary job, Mr. Katzmarzyk and his team suggest a few simple changes: get up from your desk as often as you can take walks at lunch time walk to your colleagues' offices and talk directly instead of emailing them All these activities may help you live longer. What might be the best title for the passage?
Choices:
A. Take exercise, keep fit.
B. Change more, achieve greater.
C. Talk directly, improve relationship.
D. Sit less, live longer. | D |

In order to increase their job chances after college, Chinese students are turning to a special practice--Eiffel Tower nose jobs . The latest trend in plastic surgery promises to create a nose that is similar to the curve of the Eiffel Tower. Surgeon Wang Xuming said: "We are influenced by the beauty of the Eiffel Tower. We are not content to just add something to the nose; we reconstruct it." The surgery costs about US$ 10,000 and involves the enlarging of the nose using tissue from the forehead. Hundreds of posters advertising the procedure are put up all over Chongqing city, where surgeon Xuming runs his private practice. They show a western-looking woman with an almost-too-perfect nose, against an outline of the Eiffel Tower. Interestingly, many young women in China are eager to achieve a western appearance, as they believe it will give them an advantage in the highly competitive job market. "Some students face a lot of employment pressure after graduation. If their facial features are good, they'll have more chances of finding a job," said surgeon Xuming. "We've had students getting the Eiffel Tower nose; it's helped them a lot." Apparently, Chinese employers are quite particular about appearances and prefer attractive candidates. Some of them even go as far as putting height and weight requirements in their employment ads. Plastic surgeons across the country are reporting an increase in the number of students choosing beauty "improvement". According to a Mr. Li, hospital manager at surgeon Xuming's clinic, most of their customers are female and the bill is taken care of by the family. "They usually come in with their mothers, and tend to be from well-off backgrounds." he said. Personally, I don't think it so important to "improve" our appearance as long as we are skilled at our jobs. We can't decide how we look, but we can decide how well we live and work. Why do Chinese college students choose to have a nose operation?
Choices:
A. To have more chances of getting a job.
B. To gain a real westerner appearance.
C. To Take good care of their family.
D. To look like the Eiffel Tower. | A |

She was born to wealth and power in a time when money and politics were left to the men. Later, as The Washington Post's publisher, Katharine Graham became one of America's most powerful women. Despite a privileged background, Katharine had to deal, while growing up, with the high demands her mother placed on her children.Katharine's love of journalism, which she shared with her father, led to her career after college at The Washington Post, the newspaper her father bought in 1933.At the Post, Katharine met Phil Graham, a young, charming lawyer who became her husband.When, in 1945, Katharine's father chose Phil over her to take over his struggling paper, Katharine didn't object and stayed at home as a wife and mother of four. While Phil's successful efforts to restore the Post to fame made the Grahams popular members of the Washington social scene, Katharine privately suffered great pain from her husband's increasingly harmful behavior caused by severe depression.When Phil committed suicide , the 46-year-old Katharine found herself thrown into a new job, that of newspaper publisher.But determined to save the family paper for her children, Katharine rose to the challenge of running the Post, attending meetings in every department, working endlessly to prove herself to her critics, and becoming the toast of Washington. In 1971, Katharine ordered the Post to print a copy of the Pentagon Papers, the top-secret documents telling the truth about the United States' involvement in the Vietnam War.What's more, her courageous decision and support for her journalists prepared the Post to break the most important political story in modem history: Watergate , one of the greatest scandals in American political history.Katharine managed to keep control over the most disorganized situation when it was reported, all the time insisting the news stories be accurate and fair.Watergate made the Washington Post an internationally known paper and Katharine was considered as the most powerful woman in America. .Katharine Graham was born in a time when _ .

The expression "a thirst for knowledge" may soon have a new meaning for millions of people who have no way to get clean water. Researchers have developed a book with specially treated pages that can turn dirty water into clean and drinkable water. They say their invention could improve the lives of many in the developing world. About 700 million people around the world are at risk of disease or even death because their drinking water is not clean. The water is polluted by harmful bacteria. The book contains 25 pages. Each page is about one millimeter thick. The pages contain very small particles of silver. The pages can be used as filters to remove harmful microorganisms that can pollute drinking water. The filter kills the organisms that pass through it. Pictures on the pages show the dangers of dirty water and how to use the book for those unable to read. The pages are made of filter paper. They are designed to be torn from the book. Water can be poured through the paper to be cleaned. Ms. Dankovich, the inventor, says each page can treat up to 100 liters of water. She recently presented her invention at the meeting of the American Chemical Society in Boston, Massachusetts. She was asked whether she had considered adding classic literature on the book's pages. "The idea of classic texts--that's of interest maybe later. We have discussed a little bit more exciting text. But we really haven't had the time to go through _ " she says.

mmlu | Question:
Our love of music and appreciation of musical harmony is learnt and not based on natural ability, a new study by University of Melbourne researchers has found. The researchers said previous theories about how we appreciate music were based on the physical functions of sound, the ear itself and a born ability to hear harmony. The study shows that musical harmony can be learnt, and it is a matter of training the brain to hear the sounds. So if you thought that the music of some foreign culture (or Jazz) sounded like the crying of cats, it's simply because you haven't learnt to listen by their rules. The researchers used 66 volunteers with a range of musical training and tested their ability to hear combinations of notes to determine if they found the combinations familiar or pleasing. They found that people needed to be familiar with combinations of notes. If they couldn't recognize the notes, they found the notes _ . This finding put an end to centuries of theories claiming that physical functions of the ear determine what we find attractive. The study found that trained musicians were much more sensitive to unpleasant notes than non-musicians. When they couldn't find the note, the musicians reported that the sounds were unpleasant, while non-musicians were much less sensitive. This shows the importance of training or nurturing the brain to like particular sound of combinations of notes, like those found in jazz or rock. Depending on their training, a strange chord sound was pleasant to some musicians, but very unpleasant to others. This showed us that even the ability to hear a musical note is learnt. To confirm this finding, they trained 19 non-musicians to find the notes of a random selection of western chords. Not only did the participants' ability to hear notes improve rapidly; the chords they had learnt sounded more pleasant--regardless of how the chords were played. The question of why some combinations of musical notes are heard as pleasant or unpleasant has long been debated. " We have shown in this study that for music, beauty is in the brain of the beholder ," a researcher said. What is the best title for the passage?

A. Improve Your Brain By Listening to Music
B. You Can Be a Musician Without Being Trained
C. Music Can't be Taught

They may be just passing your office, computer bag slung over one shoulder. Or they may be sitting in a car outside it, causally tapping away at a laptop. They look like innocent passers-by. In fact, they are stealing your corporate secrets. Drive-by hacking is the trendy term given to the practice of breaking into wireless computer networks from outside the buildings that house them. A recent study in the UK, sponsored by RSA Data Security, found that two-thirds of organizations with wireless networks were risking their data in this way. Security experts patrolled several streets in the City of London seeking evidence of wireless networks in operation. Of 124 that they identified, 83 were sending data without encrypting them. Such data could readily be picked up by a passer-by armed only with a portable computer, a wireless modem and a few pieces of software that can be freely downloaded from the Internet. The data could include sensitive company documents containing valuable information. Or they could be e-mail identities and passwords that could be used by hackers to log into corporate networks as if they were legal users. Most companies using wireless networking technology do not take even the simplest of measures to protect their data. Nearly all wireless network technology comes with some basic security features that need only to be activated in order to give a minimum level of security, for example, by encrypting the data being passed over the network. Raymon Kruck, business development manager at Check Point Software, a security technology specialist, believes this could be partly a psychological problem. People see the solid walls of their building as safeguards and forget that wireless networks can extend up to 200 meters beyond physical walls. Companies without any security at all on their wireless networks make it ridiculously easy for hackers to break in. Switching on the security that comes with the network technology should be automatic. Then there are other basic steps a company can take, says Mr. Kruck, such as changing the passwords on the network from the default setting. Companies can also install firewalls, which form a barrier between the internal network and the public Internet. They should also check their computer records regularly to spot any abnormal activity, which might betray the presence of a hacker. According to the study sponsored by RSA Data Security, two thirds of the subjects _ .
Choices:
A. had most of their company data stolen
B. depended on wireless computer networks
C. were exposed to drive-by hacking
D. were unaware of the risk of wireless hacking | C |

Farmers could grow more rice and shaky Internet communications could work better someday, thanks to prize-winning discoveries by teenage scientists showed at a national science fair on Monday. High school scientists from across the United States showed off work in genetics, molecular biology, mathematics and other fields that judges said rose to the professional level. "It just blows me away. They're all just unimaginable," said Joel Spencer, aprefix = st1 /New YorkUniversityprofessor who served as judge at the Sidemen's Westinghouse Competition in Math, Science and Technology. Research done by finalists in the nationwide competition could lead to faster Internet speeds, more effective antibacterial drugs and better energy conservation. One team researched black holes in outer space, while another examined more than 700 fossils to better understand why dinosaurs died out. Juliet Girard and Roshan Prabhu won $ 100,000 scholarship for their work proving genes that help some kinds of wild rice flower earlier than others. Drawing on a database that described the genetic makeup of rice, the two students, fromJersey City,New Jersey, identified two genetic sections that directed wild rice to blossom an average of 10 days earlier than the ordinary short-grain rice that feeds much of the world. Their discovery could allow genetic engineers to develop a new strain that would take less time to reach maturity, allowing farmers to produce more and extending the growing region into colder climates. Steven Byrnes of Lexington,Massachusetts, took the top individual prize for his theory describing outcomes in a two-player game called Chomp. _ competed at the national science fair.

mmlu | Question:
The behavior of a building's users may be at least as important as its design when it comes to energy use, according to new research from the UK Energy Research Centre (UKERC). The UK promises to reduce its carbon emissions by 80 percent by 2050, part of which will be achieved by all new homes being zero carbon by 2016. But this report shows that sustainable building design on its own--though extremely important--is not enough to achieve such reductions: the behavior of the people using the building has to change too. The study suggests that the ways that people use and live in their homes have been largely ignored by existing efforts to improve energy efficiency, _ instead focus on architectural and technological developments. "Technology is going to assist but it is not going to do everything,"explains Katy Janda, a UKERC senior researcher, "consumption patterns of building users can defeat the most careful design." In other words, old habits die hard, even in the best designed eco home. Another part of the problem is information. Households and bill payers don't have the knowledge they need to change their energy use habits. Without specific information, it's hard to estimate the costs and benefits of making different choices. Feedback facilities, like smart meters and energy monitors, could help bridge this information gap by helping people see how changing their behavior directly affects their energy use; some studies have shown that households can achieve up to 15 percent energy savings using smart meters. Social science research has added a further dimension, suggesting that individuals' behavior in the home can be personal and cannot be predicted--whether people throw open their windows rather than turn down the thermostat , for example. Janda argues that education is the key. She calls for a focused program to teach people about buildings and their own behavior in them. As to energy use, the new research from UKERC stresses the importance of _ .

A. zero carbon homes
B. the reduction of carbon emissions

NEW YORK (AP) -- The investigation into the disappearance of 6-year-old Etan Patz has gone through decades and countries, from basements to rooftops and seemingly everywhere in between. No one has ever been charged criminally -- and the little boy with sandy brown hair and a toothy grin was declared dead in 2001. This week, the six-year-old boy who went missing from the Soho area of New York City in 1979 is back in the news. Police and the FBI are investigating a possible lead into the 33-year-old case of Etan Patz, the first missing child to appear on the side of a milk box. The child disappeared on the way to school on the morning of May 25, 1979. It was the first time he was allowed to walk the two blocks to the bus stop alone. A tip seemed to have led officials to the basement of a building on the corner of Prince and Wooster streets, about a block and a half from where Etan had lived with his family. The name Etan Patz has become a hot topic on Twitter as people _ . Shirley Brady noted: "As mom to a 6 years old in Soho, it's still held out by locals as cautionary tale ." Another wrote, "Boy who disappeared on his way to school in 1979 has been REOPENED! Crazy." One wondered, "Why is FBI and NYPD searching for a kid that disappeared in 1979?" Good question. This is a case that Stuart Gra Bois, as an assistant U.S. lawyer under Rudolph Giuliani, followed for years. It became the most famous missing-person case in New York City, turned a nationwide spotlight on missing children, and created headlines around the globe. No one was ever stated guilty of the crime. The case led to the creation of National Missing Children's Day, marked on May 25, the day the blond-haired, blue-eyed child went missing. The case has even pointed to a suspect, charged with child molester Julio Antonio Ramos, who is currently in prison. Patz's babysitter had been dating the man, and Ramos did know the kid, but has denied taking him away. New evidence in the case suggests another suspect who lived in the apartment at the time: a local handyman named Othniel Miller, who gave Etan $1 for helping him the night before the disappearance. The man's name had come up in an earlier investigation, but he was a friend of the Patz family, and the NYPD did not follow the lead. Investigators plan to be at the site, 127 B Prince St., which is now a Lucky Brand jeans store, for the next two to three days to search for human remains. The Associated Press reports that the excavation has been the result of a recently ordered review of the case by Manhattan's police. Which of the following statements is true in the text?
Choices:
A. The National Missing Children's Day was created on May 25, 1979.
B. The search for human remains will be carried out at 127 B Prince Street.
C. The NYPD didn't follow the lead of Julio Antonio for he had been dating Patz' babysitter.
D. Othniel Miller, a local handyman assisted Etan and gave him $1 before the disappearance. | B |

Today there are twenty to twenty-five million shopping carts rolling around the world.In fact,the shopping cart is presently one of the most often used items on four wheels,second only to the automobile.Indeed,almost everybody in America will spend a part of his or her life behind a shopping cart.They will,in a lifetime,push it many miles.But few will know-or even think to ask-who it was that invented them. Mr.Sylvan N.Goldman of Oklahoma City invented the shopping cart in 1937.Mr.Goldman's invention did not make him famous.It did,however,make him very rich.When Goldman invented the cart he was in the supermarket business.Every day he would see shoppers lugging groceries around in baskets that they had to carry.One day Goldman suddenly had the idea of putting baskets on wheels.The wheeled baskets would make shopping much easier for his customers.And by lightening their chore,he would attract their business.Pondering the idea,Goldman walked into his office and sat down on a folding chair.Looking down at the chair,Goldman had another idea.The carts,he realized,should be made so they could be folded up.This would make it easier to store them when not in use. On June 4,1937,Goldman's first batch of carts was ready for use in his market.He was terribly excited on the morning of that day as customers began arriving.He couldn't wait to see them using his invention.But Goldman was disappointed.Most shoppers gave the carts a long look,but hardly anybody would give them a try.After a while,Goldman decided to ask customers why they weren't using his carts."Don't you think this arm is strong enough to carry a shopping basket?"one offended shopper replied. Day after day,the same thing happened.People wouldn't use the carts.They preferred a basket on the arm to a basket on wheels.But Goldman wasn't beaten yet.He knew his carts would be a great success if only he could persuade people to give them a try.To this end,Goldman tried something that was both very clever and very funny.Believe it or not,he hired a group of people to push carts around his market and pretend they were shopping!Seeing this,the real customers gradually began copying the phony customers. As Goldman had hoped,the carts were soon attracting larger and larger numbers of customers to his market.But not only did more people come-those who came bought more.With larger,easier-to-handle baskets,customers unconsciously bought a greater number of goods than before. Today's shopping carts are five times larger than Goldman's original model.Perhaps that's one reason Americans today spend more than five times as much money on food each year as they did before 1937-before the coming of the shopping cart. How did Goldman get customers to use the shopping cart?

America's No.1 health problem? A report published by the American Institute of Stress claims the biggest threat to health today is neither cancer nor AIDS. The report says: "It has been estimated that75-90 percent of all visits to primary care physicians are for stress related problems" It is no exaggeration to say that people today are being attacked by stress. According to the National Consumers League, " Work is the top source of stress for adults who have problems and stress in their lives (39%),followed by family (30%).Other sources include health (10%), concern about the economy (9%)and concern about international conflict and terrorism (4%)." However , stress is hardly unique to the United States .A British survey in 2013 estimated that "over half a million individuals in Britain believed in 2012 that they were experiencing work -related stress at a level that was making them ill ." As a result of "work -related stress, depression or anxiety ,"there are "an estimated thirteen and a half million reported lost working days per year in Britain ."\ The picture is no less bleak in mainland Europe .According to the European Agency for Safety and Health at Work , "work-related stress has been shown to affect millions of European Workers across all types of employment sectors ." One survey revealed that there are "about 41 million workers affected by work-related stress each year." What about Asia ? A report issued by a conference held in Tokyo concluded: " Job stress is a common concern among many countries in the world , both developing and industrialized countries ." The report observed that "several countries in East Asia , including China and Korea, have rapidly industrialized and economically grown .These countries now have a lot of concerns on job stress and its harmful effects on workers' health."

mmlu | Question:
1 always figured that comedians were the best kind of people to hang around with as a kid. They tell funny stories, make joke after joke, and happiness seems never to leave them. But time goes on, and we come to see these same people as clowns on the outside, but crying a river in the inside. Comedy from these people comes from a deep pain and sadness in their lives, or out of a deep-seated anger they have at the world around them. Look at Richard Pryor, need I say more? Richard seemed to have everything. For Superman m , he ended up getting more money than Christopher Reeve did. Yet he said while he was in his forties that the last truly happy moment he remembered in his life was when he was jumping around in the dirt while pretending to be a cowboy at the age of 10. This guy set himself on fire, and he played that for laugh while performing live at the Sunset Strip ! Comedy was his constant weapon against pain, and he never held anything back. The movie Funny People understand very well this gloomy field many comedians have to survive in. It stars Adam Sandler as George Simmons, a famous comedian in the movie. Simmons has it all: a beautiful mansion overlooking the sea, a swimming pool,great cars, and so on. But in his eyes, we see that he is a sad man who has come to truly look down upon himself for what he has become. All the wealth he has collected only serves to separate him from the rest of the world and it makes him defensive when around total strangers who cannot see him as a normal person. But now, he hears from his doctor that he has a terminal disease and has only months left to live. Simmons reacts to this news as if someone took away his blood in the heart, and it makes him clearly see just how much he hates his life. So now he has to make every minute count. Then come a series of funny stories. Comedy is just life as it is, isn't it? When was the happiest moment for Richard Pryor?
Choices:
A. When he played the part of SupermanIII.
B. When he got more money than Christopher Reeve.
C. When he pretended to be a cowboy in the childhood.

mmlu | Question:
We all, at one time or another, have pretended to be a rock star, singing and dancing along to our favorite song. Most of us have done this in the privacy of our own room when we were kids and as adults, in the privacy of our homes. Me? I love to do that when I drive! I turn on the radio, find a song that I can sing along too and pretty soon my arms are in the air and I am moving along to the rhythm. Most of the time, I do this on my way to work. Yes, that is true, I will be in my nice work clothes, jamming while driving or stopped at a traffic light I get weird looks from some people and others laugh. Personally, I love to get lost in the rhythm of a song which leads me to share with you the importance of being silly! The definition for the word silly, according to the dictionary is: stupid, foolish and nonsensical. I know many people do not want to look foolish. So they walk around all serious, which in all honesty, is foolish! No one is perfect, I repeat: no one is perfect. I don't care how educated, how thin, how beautiful, how simple, how frugal , how rich, and so on...No one is perfect! So why pretend to be something you are not? Life is so short. You never know when this beautiful journey will be over, so why waste a single second on being so full of rigidity ? Here is a quote by Souza, that I think says it all and is a great recipe for life: "Dance as though no one is watching you, Love as though you have never been hurt before, Sing as though no one can hear you, Live as though heaven is on earth." When we were kids, we had no idea of what limitations were and we had no care in the world so we could do things without worrying about how we appeared to others. However, as we grew up, we lost that childlike innocence. So don't lose the child that still lives within you. The next time you feel down, go turn on your favorite song, and sing and dance along like there is no tomorrow or watch something that makes you laugh. Laughter is the best medicine to whatever ails (......) you and nothing is better than laughing so hard that your stomach hurts. Trust me, you will feel a whole lot better, and who doesn't want to feel good? Which of the following would be the best title for the text?

It is a wonderful morning,as I write this:hot,but without being too hot. Outside my window,I can see the sunniest sky of the year reflected in a huge natural expand of water. It is the kind of sun that makes you well aware of summer's temporary nature --a reminder that if I am ever to go around to book this year's holiday,time is running out . It is now close to four years since I last took a holiday. This is because I have come to the conclusion, over the course of my adult life, that I am not very good at it. _ What could possibly be difficult about the natural act of putting your working life on hold for a couple of weeks and going somewhere to do nothing? So what is my problem? On the surface, I'm probably a bit of homebody. And I just find the pressure of being on holidy too severe: it always feels like having a gun held to my head and being forced to have fun. Somehow, packing a carefully itemized list of possessions and meeting a scheduled flight has none of the excitement of suddenly deciding to take a day off and driving somewhere for the fun of it. Thankfully, I am not alone. This summer, most of my friends have decided not to have a break. And a recent survey highlighted the downside of holidays, with the results shoeing that nearly two thirds of people found that the calming effects of a holiday wore off within 24 hours, as stress levels returned to normal. And this year's the Idler magazine published its book of awful holidays .Here you will find a list of the five most ecologically--damaging vacations it's possible to take, along with 50 horrible holidays experiences voted for on the idler website. Over the last decade, The Idler has become well known for promoting the idea of an easy, lazy life.

For Americans, a mosquito bite is an itchy bother. But for many in Africa, a tiny bite can be deadly. One million people die each year of malaria, a disease spread by infected mosquitoes. Most of these people live in Africa, and are under age 5. Malaria can be prevented and treated. However, many African nations don't have the funds to fight it. Nothing but Nets (NBN) hopes to change that. The United Nations Foundation created the campaign in 2006. The aim is to prevent malaria by covering sleeping areas with nets. Hanging bed nets treated with insecticide is the simplest way to stop mosquitoes from biting at night. The chemicals last four to five years. For $10, anyone can send a net to Africa and help save a life. So far, NBN has raised $19 million and delivered 700,000 nets to seven countries. Families are taught how to use the nets. Kids also get vaccines and vitamins. "Women line up for miles to get the medicine for their kids," says NBN director Elizabeth McKee Gore. "They understand the importance." So do kids in this country. "They get so excited thinking of ways to raise money," says NBN spokesperson and basketball star Ruth Riley. NBN's biggest fund-raiser is Katherine Commale, 7. She's been spreading the information about bed nets for the past two years. To show how they work, she and her brother made a video. "We teach that bed nets can save lives," she said. Katherine has raised $42,000 for NBN. "She just wants those who need a net to have one," says her mom, Lynda. "It's pretty simple to her." To find out how you can help, visit nothingbutnets.net.

Musa Kayairanga of Rwanda is a traditional healer. He uses natural medicines to treat his patients. He learned how to use computers at a rural telecommunications center in his country. Musa Kayairanga says he exchanges information with doctors as far away as Canada. He also says the computer has improved his knowledge of using plants to treat diseases. Many people in rural areas are now able to communicate with the rest of the world. This is one example of how technology is changing life in developing countries. Andrew Burns is an economist at the World Bank in Washington, D.C. He led a recent study of technology in developing countries. The study found that technology has spread faster in such countries than in rich nations. It also found that technological progress has helped raise wages in developing countries. And it reduced the percentage of people living in extreme poverty from twenty-nine percent in 1990 to eighteen percent in 2004. Progress in communications technology has aided the growth of call centers in developing countries. Call centers are offices where most telephone calls for a business can be answered. For example, a woman in the United States who calls her computer company about a problem might speak with someone in India or Pakistan. Call centers serve businesses in local and international markets. And they have added to economic growth by providing well-paid jobs and new skills for workers who might not have had such employment. Ahsan Saeed is a young call center worker in Karachi, Pakistan. He says the job improves his language skills, his sales skills and his ability to deal with people.( from VOA Special English ) Since Musa began to use the computer , he _

From our smartphones to our latest weaponry, the technology that underpins modern life would be impossible without rare earth metals. The importance of rare earths has only grown as emerging markets increase their demand for technologies made with it, as does the renewable energy industry. The 17 metallic elements are common in the earth-s crust, but the technique used to extract and refine them is labor-intensive, environmentally hazardous and increasingly costly. Thomas Gradael, a professor of geology and geophysics at the Yale School of Forestry Environmental Studies, explains that thecriticality" of rare earths was only recently understood after China, which dominates the world-s supply of the minerals, cut exports by 40% in 2010, citing concerns over how polluting the rare earth industry was. Along with colleagues at Yale, Gradael decided to investigate the metals used in modern technologies to determine if there were viable substitutes."Twenty or thirty years ago electronics were being made with 11 different elements," explains Gradael. "Today's computers and smartphones use something like 63 different elements." Their findings showed that there were no "readily apparent" substitutes for a metal that would not compromise on quality or performance. However increased mining for these scarce resources can have some nasty side effects for the environment. China, which has intensively mined for rare earths with little regulation, allowing it to dominate the global industry since 1990, has acknowledged the incredible environmental harm caused by the process. "Excessive rare earth mining has resulted in landslides, clogged rivers, environmental pollution emergencies and even major accidents and disasters, causing great damage to people's safety and health and the ecological environment," read a white paper issued by the Chinese cabinet in June last year. Recycling metal has been advocated by some as a possible way of managing these precious resources-the European Parliament adopted a law curbing dumping of electric waste in 2012. But Gradael says that for rare earths, recycling will have little impact. Which one of the following can be used in the blank?
Choices:
A. It is in China that rare earths are fully understood.
B. Despite the name, rare earth metals are not in fact rare.
C. There is a growing concern over the rare earth industry.
D. Rare earth metals are difficult to collect though important. | B |

mmlu | Question:
I credit my typing skill to so many hours of chatting online. Unfortunately, as my typing speed increased on the Internet, all grammatical rules _ You see instant messages have their own shorthand language and grammar isn't important, of which even a newbie is aware. They can leave out articles, subjects , pronouns, etc. They can misspell or "respell" almost any word. They often ask "A/S/L" when they first chat. Abbreviations and capitalizations are particularly important. English-speaking instant messengers also refuse to burden themselves with punctuation and capitalization. After I came back China, I discovered not one but two instant messaging crazes. The first, which brought back memories of my previous addiction to the computer, was QQ. I can see evidence that the Chinese have the same kind of separate instant messaging language, even when they chat in English. My first word in this language, for example, was "ft". This abbreviation for "faint" is used whenever there is a need to express surprise. I also discovered that Chinese use the same kind of abbreviation for a laugh. And there is an extraordinary number of smileys to the "vomit" and "army soldier" smileys. There is even a SARA smiley. After QQ, there is another, perhaps more widespread messaging trend. You guessed it --- cell phone text messaging. I now understand how useful text messaging is and why it is so common. I admit that I have been guilty of sending text messages while walking outside or sitting on the subway. Who hasn't ? No matter where I go, I see people on their cell phones, messaging. In fact, it's rare to see someone actually talking on their phone! So it looks as if there is no escape from the instant messaging crazes, no matter where in the world I go. And that's plainly not going to change. In the end, though, I can't complain: instant messaging is quick, it's cheap, it's easy and it's extremely fun too. And after all, everyone's doing it. Which might be the main idea of the passage?

C. Chatting online is good for your typing skill.

We have to accept the truth: Sometimes, we just want to shout out loud. For example, we all have days like this: our dog has made a mess on the floor we just cleaned, or our friend called to tell us he or she couldn't come at the last minute when we had cooked dinner for him or her. We may be really angry but we tried to bear things like those. According to ancient Chinese wisdom, we should shout in a loud voice instead of keeping silent. In fact, it's good for our health. "Chinese people have passed on the practice from ancient times to now as a part of traditional medicine," said Mrs. Li, a 60-year-old woman from Hangzhou. "My parents taught me to do this. It's a part of our folk culture. " Mrs. Li is a member of a group of people who love shouting. Each morning, she and some of her friends climb to the top of a hill and let out loud shouts before starting their daily exercise. They believe that shouting is good exercise for their lungs and it brings them a lot of fun. "Sometimes I shout out and other shout back," said Mrs. Gu, another shouting lover. "It makes you happy. You laugh and then you feel very comfortable. " Dr. Peter Calafiura, an American doctor, agrees that shouting can have a positive influence on people's health.

A young man approached the foreman of a logging crew and asked for a job. "That depends," replied the foreman. "Let's see you fell this tree." The young man stepped forward and skillfully felled a great tree. Impressed, the foreman said, "You can start Monday." Monday, Tuesday, Wednesday, Thursday went by -- and on Thursday afternoon the foreman approached the young man and said, "You can pick up your wages on the way out today." Shocked, the young man replied, "I thought you would pay me on Friday." "Normally we do," said the foreman. "But we're letting you go today because you've fallen behind. Our daily felling charts show that you've dropped from first place on Monday to the last place today." "But I'm quite hardworking," the young man disagreed. "I am the first to arrive and the last to leave and even have worked through my coffee breaks!" The foreman thought for a minute and then asked "Have you sharpened your axe?" The young man replied, "No, sir. I've been working too hard to take time for that!" Our lives are like that. We sometimes get so busy that we don't take time to "sharpen" the axe. In today's world it seems that everyone is busier than ever, but less happy than ever. Why is that? Could it be that we have forgotten how to stay sharp? There's nothing wrong with hard work. But we shouldn't get so busy that we ignore the truly important things in life. We all need time to relax, to think, to learn and to grow. If we don't take time to sharpen the axe, we will become dull and lose our effectiveness. What can we learn about the young man?

A. He is optimistic.
B. He is a little dishonest.
C. He is intelligent.
D. He is hardworking. | D |

It is a truth universally acknowledged that . However little known the feelings or views of such a man may be on his first entering a neighborhood, this truth is so well fixed in the minds of the surrounding families that he is considered the rightful property of someone or other of their daughters. "My dear Mr. Bennet," said his lady to him one day. "have you heard that Netherfield Park is let at last?" Mr. Bennet replied that he had not. "But it is, " returned she, "for Mrs. Long has just been here, and she told me all about it." Mr. Bennet made no answer. "Do you not want to know who has taken it?" cried his wife impatiently. "You want to tell me, and I have no objection to hearing it." This was invitation enough. "Why, my dear, you must know, Mrs. Long says that Netherfield is taken by a young man of large fortune from the north of England; that he came down on Monday in a chaise to see the place, and was so much delighted with it, that he agreed with Mr. Morris immediately; that he is to take possession before Michaelmas, and some of his servants are to be in the house by the end of next week." "What is his name?" "Bingley." "Is he married or single?" "Oh! Single, my dear, to be sure! A single man of large fortune; four or five thousand a year. What a fine thing for our girls!" How so? How can it affect them? "My dear Mr. Bennet," replied his wife, "how can you be so tiresome! You must know that I am thinking of his marrying one of them." "Is that his design in settling here?" "Design! Nonsense, how can you talk so! But it is very likely that he may fall in love with one of them, and therefore you must visit him as soon as he comes." "I see no occasion for that. You and the girls may go, or you may send them by themselves, which perhaps will be still better, for as you are as beautiful as any of them. Mr. Bingley may like you the best of the party. " The sentence "... a single man in possession of a good fortune must be in want of a wife" means that _ .
Choices:
A. a single man without money needn't a wife
B. women want to get married to financial stable men
C. a single man who is financially stable needs a wife
D. once man becomes rich, he must want to get a wife | C |

Nodira, 18, lives in the Tashkent region of Uzbekistan. She was born with a rare disease and is now paralyzed from the waist down. Her life is confined to a wheelchair but _ Her hopes for the future include attending university, riding in her father's car and being able to walk like other children. Nodira, which means 'unique' in Uzbek, is one of five children in a poor family. Every morning, after reciting her prayers, Nodira feeds the hens and goats from her wheelchair. The rest of her day is spent knitting for other people and helping her mother with the household chores. Nodira has never been to school because it is too far from her home and inaccessible for her wheelchair. A local teacher used to come and _ her at home and, as a result, she was able to finish third grade. After that, her parents moved to another town and the tutor could not visit as much. Despite the many difficulties in Nodira's life she is lucky to be living with her family. The stigma attached to the children living with disabilities, combined with the lack of wheelchair access in schools and the economic difficulties faced by many Uzbek families, have led many parents to place children with disabilities in special institutions. These days, Nodira does homework exercises at home and reads as much as she can. Still, it is unlikely that she will be able to finish her primary education, much less attend university. While missing out on an education is a great disappointment to Nodira, her greatest wish, for a true friend, can still come true. "What I want more than anything is a friend who also has a disability," she says. "Somebody will not feel sorry for me or make fun of me, and will understand what my life is like." Nodira does all the following every day EXCEPT _ .

When I was at University I studied very hard. But a lot of my friends did very little work. Some did just enough to pass exams. Others didn't do quite enough. Fred Baines was one of them. He spent more time playing than working in the library. Once at the end of the term, we had to take an important test in chemistry. The test had a hundred questions. Beside each question we had to write "True" or "False". While I was studying in my room the night before the test, Fred was watching TV. Fred usually worried a lot the night before a test. But on that night he looked perfectly calm. Thenhe told me of his plan. "It's very simple. There are a hundred questions and I have to get fifty correct to pass the test. I'll just toss the coin to decide the answers. That way, I'm sure I'll get half the questions right." The next day, Fred came happily into the exam room. As he sat tossing a coin for half an hour he marked down his answers. Then he left, half an hour before the rest of us. The next day, he saw the chemistry professor in the corridor. "Oh, good," he said to the teacher, "Have you got the result of the test?" The teacher reached into his pocket and took out a coin. He threw it into the air, caught it in his hand and looked at it. "I'm terribly sorry, Fred," he said, "You failed!" This story mainly wants to tell us _ .

mmlu | Question:
In the animal kingdom, weakness can bring about aggression in other animal. This sometimes happens with humans also. But I have found that my weakness brings out the kindness in people. I see it every day when people hold doors for me, pour cream into my coffee, or help me to put on my coat. And I have discovered that it makes them happy. From my wheelchair experience, I see the best in people, bur sometimes I feel sad because those who appear independent miss the kindness I see daily. They don't get to see this soft side of others often. We try every way possible to avoid showing our weakness, which includes a lot of pretending. But only when we stop pretending we're brave or strong do we allow people to show the kindness that's in them. Last month, when I was driving home on a busy highway, I began to feel unwell and drove more slowly than usual. People behind me began to get impatient and angry, with some speeding up alongside me, horning or even shouting at me. At the moment I decided to do something I had never done in twenty four years of driving. I put on the car flashlights and drove on at a really low speed. No more angry shouts and no more horns! When I put on my flashlights, I was saying to other drivers, "I have a problem here. I am weak and doing the best I can." And everyone understood. Several times, I saw drivers who wanted to pass. They couldn't get around me because of the stream of passing traffic. But instead of getting impatient and angry, they waited, knowing the driver in front of them was in some way weak. Sometimes situations call for us to act strong and brave even when we don't feel that way. But those are few and far between. More often, it would be better if we don't pretend we feel strong when we feel weak or pretend that we are brave when we are scared. The author has discovered that people will feel happy when _ .
Choices:
A. they offer their help
B. they receive others' help
C. they feel others' kindness
D. they show their weakness | A |

Do you like to eat sushi ? Many people are afraid to eat it, because they think the bacteria in it might make them sick. However, a new study shows that sea bacteria are good for people. The study finds that a special enzyme from sea bacteria is helpful to humans. It helps people to get more energy from food. To people's surprise, the enzyme is present only in the Japanese. The Japanese traditionally like to eat food rich in seaweed . And the seaweed is rich in this kind of enzyme. However, the enzyme isn't present in all the Japanese. During the study, just 5 out of 14 Japanese had the enzyme. All the Americans studied didn't have the enzyme. "The number is small," said researcher Mirjam Czjzek. "But we can say that this enzyme is present only in the Japanese and not in the North Americans." Then some people think that maybe other people are able to get the enzyme if they eat a lot of seaweed. The study suggests that they collect uncooked seaweed to make their sushi. Restaurant sushi is often cooked, which will destroy the enzyme. So, if you want to get that enzyme, you can travel to Japan to have a taste of the real sushi. Sea bacteria are _ for people.
Choices:
A. helpful
B. harmful
C. important
D. necessary | A |

In my twenty-six years as a free writer, I have worked for newspapers, magazines and the Internet sites. I have reviewed the famous people, and criticized the political characters. Yet along my journalistic journey there have been several interviews that remain deeply in my memory. For not only did the characters of those specific people impress me, they actually influenced my life. Lynn R. Taylor is such a special person. Born in Buffalo, New York, on May 2, 1962, Lynn Taylor was just like all the other kids in her neighborhood. At the age of three she was diagnosed with Wilms Tumor, a cancer of the kidneys. Given a "no-chance" prediction, doctors completely removed one of Lynn's kidneys and part of another. They then predicted that if she survived to the age of five, she might possibly make ten. In the decade that followed, Lynn Taylor met and surpassed all medical experts' gloom-and-doom predictions. At the age of fourteen she was in full remission , and by seventeen, she was considered cured. Yet in this case, Lynn's medical history was far from closed. Over the next twenty-three years, Lynn earned her undergraduate degree and master's degree in economics. Then she was awarded a scholarship to study at the University of Sussex in England. There she was invited to teach and earned her second master's degree. Upon returning to Buffalo, the successful young woman engaged in a variety of high level jobs, including head of Multicultural Affairs at a local college. Recently Lynn has added a new activity to her schedule----that of a cancer hospital volunteer. It is her wish to provide living proof for patients that cancer is not necessarily a death sentence but rather, as she has proved, something to overcome. When Lynn Taylor was diagnosed with cancer, the doctors _ .

mmlu | Question:
What shapes a man's ability and skill was always a question to psychologists until a few decades ago when findings show that they for the most part come from practice ---- repetitive and endless practice. The psychologist K. Anders Ericsson of the University of Florida and his team, based on a survey of a violin class in a college of music, have found that the students whose levels are rated as "A" have spent on average over 10,000 hours on violin-practice, those with level B a bit less than 8,000 hours, and those with average or lower levels no more than 5,000 hours. The result of the survey is widely preferred because it suggests that practice makes perfect, that is, the distinction between "excellent" and "good" lies more in hard work than in natural intelligence. Malcolm Gladwell points out in his latest book Outliers: The Story of Success: "Practice isn't the thing you do once you're good. It's the thing you do that makes you good." Besides, he thinks IQ plays little part in the formation and development of ability. "When one has an IQ of 120," writes he, "what is beyond it does not make an evidential difference in real life." However, scientists' experimental results are quite different from the psychologists'. Their findings show success in many areas depends on intelligence --- and not a little. David Lubinski and Camilla Benbow of Vanderbilt University, with their research group, carried out a milestone research. They selected from Youth Talented Search 2000 teenagers of or under 13 whose SAT results ranked top1%. After tracking the achievements the 2,000 "wonder children" made in academy and career, Lubinski and Benbow's group found that those ranking top 1% have more possibility (averagely by two to four times) to get a doctor's degree, a certificate, and publish academic theses and works than those ranking top 9%. As a conclusion, it's a great advantage in the real world to have a high IQ. Psychologists' conclusion is popular among people probably because _ .
Choices:
A. everyone sees a chance to succeed through practice
B. hard work plays as important a part in success as IQ
C. they are told that IQ makes no difference in real life
D. there is no difference between "excellent" and "good" | A |

BAGRAM, Afghanistan: A transport helicopter packed with US soldiers crashed near a military base just north of the capital, killing at least five of them and wounding seven others, the US military said yesterday. The cause of Sunday's crash, about 11 kilometers east of Bagram Air Base, was not immediately known. The US military said it was investigating, and it refused to take journalists from the base to the crash site. But after a long search, reporters found the wreckage in a remote area yesterday afternoon. It was broken into three pieces, some of which had fallen into a mostly dry riverbed. About 15 US soldiers were guarding the site. A statement sent by email from Central Command, in Tampa, Florida,on Sunday said,"Early reports indicate seven service members were killed," when the US military helicopter went down. At Bagram Air Base yesterday morning, US military spokesman Major Richard Sater said the plane was an MH-53 transport helicopter and confirmed that it was involved in all ongoing military operation, dubbed Mountain Resolve, taking place in the east of the country. He referred all other questions, including the numbers of casualties and the cause of the crash, to Central Command officials. Bagram Air Base, just north of the capital, is home to most of the peacekeepers patrol Kabul. In another development, three US soldiers were killed on Sunday in Iraq. Gunmen in Mosul shot two American soldiers driving through the city center, sending their vehicle crashing into a wall. About a dozen swarming teenagers dragged the men out of the wreckage and beat them with concrete blocks, witnesses said. In recent weeks, attacks against US troops and their Iraqi allies--such as policemen and politicians working for tile interim Iraqi administration--have increased in the region surrounding Mosul. In Baqouba, just north of Baghdad, insurgents detonated a roadside bomb as a 4th Infantry Divison convoy passed, killing one soldier and wounding two others, the military said on Sunday.

Long ago in a small village, there was a place. It is famous for the House of 1000 Mirrors. A small, happy little dog learned of this place and decided to visit. When he arrived, he jumped happily up the stairs to the doorway of the house. He looked through the doorway with his ears lifted high and his tail wagging as fast as it could. To his great surprise, he found himself looking at 1000 other happy little dogs with their tails wagging just as fast as his. He smiled a great smile, and was answered with 1000 great smiles just as warm and friendly. As he left the house, he thought to himself, "This is a wonderful place. I will come back and visit often." In the same village, another little dog, who was not quite as happy as the first one, decided to visit the house. He slowly climbed the stairs and hung his head low as he looked into the door. When he saw the 1000 unfriendly-looking dogs looking back at him, he _ at them and was afraid to see 1000 little dogs growling back at him.

mmlu | Question:
Who do you feel closer to -- your mom or your dad? In almost every culture in the world, mothers are thought to be more important than fathers during children's development and more likely to build strong bonds with their children. This belief had existed for a long time until scientists started asking a new question: What do fathers contribute to their children besides their genes? They must mean something, or they would have disappeared from children's lives at an earlier time in evolution . So, a new science of fatherhood was born. American journalist Paul Raeburn collected the discoveries over the years and put them into his new book, Do Fathers Matter? What Science Is Telling Us About the Parent We've Overlooked, hoping to make people better see the many ways that fathers influence their children. For example, Ronald Preston Rohner, a scientist at the University of Connecticut, US, spent several years studying how being accepted or rejected by parents influences children's personality. He found that children who are accepted by both their parents are usually independent and hold a positive worldview while those who feel turned down by either parent may turn out hostile and negative. Melanie Horn-Mallers, a psychologist at California State University, found that sons who have happy memories of their fathers are better able to handle day-to-day stress after growing up. Another study, by Richard Koestner at McGill University, Canada, focused on how children develop empathy . After looking at various possible factors, Koestner found one to be more important than others -- how much time their fathers spend with them. "We were amazed to find that how affectionate parents were with their children didn't matter much to the development of empathy," said Koestner. "And we were astounded at how strong the father's influence was." Indeed, evidence shows that fathers make unique contributions to their children's happiness. However, that doesn't mean that children in families without fathers are definitely going to become failures. Just look at US President Barack Obama. He is a great example of what can be achieved by people who grow up in single-mother households. It's been discovered by scientists that children feeling refused by their parents _ .

A. often shape their own ideas
B. are less likely to be successful
C. usually manage to live with stress

I was on the escalator in a market. There was an old man who was about five or six people in the front of me. People behind him were all in a hurry and saw him as a rock. The old man knew these clearly and tried hard to step aside. I remember...Sometimes when walking or driving behind an older person, I've gotten impatient and upset. "I'm sorry. Please forgive me!" said the old man, "I don't mean to hold you up." He then tried his best to get off the escalator. I suddenly saw this in a whole new light. I felt sick to my stomach. The old man was apologizing to everyone, when we should have helped him to calm his fears. One by one, people went around him quickly. By the time I got to him, I asked, "Sir, can I help you?" The man thought for a while, then said, "Well, yes, thank you!" I placed my hand under his left arm and walked away from the rush of people quickly. "So what are you shopping for, sir?" "Oh, today is Mother's Day. I want to buy something for my neighbor. She's a single mother and she is always so nice to me." he said, stopping suddenly as he searched his pocket. "Oh, it's here! I always carry them with me," he said. Then he took out some business cards and handed me one which read: "John Smith. Friend to all...enemy to no one! I said a prayer today and you were the answer.

Passage 3 A smile will tell people around you that you are a kind and friendly person. However, many people don't smile because they think they have ugly teeth. For example, one of my classmates, Mike, doesn't have very nice teeth, so that is why he seldom opens his mouth. He even says that he has lost confidence because of his teeth. So it is very important for us to look after our teeth. In fact, a lot of people have this problem. Some people inherit teeth problems from their parents, while others' teeth are damaged because of bad habits, like heavy smoking, eating too much sugar or not brushing teeth often. If your teeth are in bad shape, you should see a dentist and ask for help. They can help improve your teeth and tell you how to take care of them. Smiling can help you to feel more confidence and make people think of you as a more friendly person. If you want to keep healthy, you should not only smile but also laugh. An Indian doctor called Kataria said that young children should laugh about 30 times a day, while adults should laugh between 7 and 15 times a day. So please take this chance to smile and laugh now. What can a dentist do according to the passage?

A friend asks you to be a volunteer. Your husband asks you to glance over an e-mail he is writing to his boss. You say you'd love to. Really! But..."I don't have time". It seems plausible( ). We're all busy these days, right? But there are reasons not to use these four words, at least with yourself. Here's the big one: _ is not true. You tell yourself "I don't have time" to exercise, but we all have 168 hours a week. If someone offered to pay you $100,000 a week to go to the gym for 5 of those 168 hours, you would probably find the time to do it. Since that isn't going to happen, this is a more exact description: " It's not a priority ." There are a million things we could be doing with our time; some are priorities and some are not, even if it's wrong to say so. Try it. "I'm not going to read to you tonight, sweetie, because it's not a priority. Daddy's present priority is to check my e-mails." Using the words "I don't have time" keeps us from admitting to the fact that how we spend our time is a choice. It puts the responsibility for our lives on someone else: a boss, a client or a family member. Better to be truthful: "I have another volunteer job on which I am focusing my energy right now. It is the cause that is most important to me." Or, to your husband "I wish you had mentioned this earlier. Right now, my priority is to get our children dressed and out of the door for school. I will be available around lunch time if you would like to talk". Which would be the best answer if your friend asks you to be a volunteer?
