mmlu | Question:
Soon computers and other machines will be able to remember you by looking at your eyes! The program works because everyone's eyes are different. So in the future you won't have to remember a number when you want to use a machine or take money out of a bank. You'll just have to look at the machine and it will be able to tell who you are. The eye-recognition program is already being tested in shops and banks in the USA, Britain and France. Soon, this technology will change all other ways of finding out who people are. However, scientists are working on other systems. Machines will soon be able to know you from the shape of your face or hands or even your smell! We already have machines that can tell who you are from your voice or the mark made by your fingers. Eye-recognition is better than other kinds because your eyes don't change as you get older, or get dirty like hands or fingers. And even twins have different eyes, so the program can be up to 94% correct, depending on how good the technology is. Some programs may only be right 51% of the time. In Britain, it was found that 91% of people who had tried it said that they liked the idea of eye-recognition. In the future your computer will be looking at you in the eye. So smile! How does the eye-recognition program work?
Choices:
A. You type a number.
B. You look at the machine.
C. The machine listens to your voice.
D. You need to walk with the machine. | B |

"Fingers were made before forks." When a person gives up good manners, put aside knife and fork, and dives into his food, someone is likely to repeat that saying. The fork was an ancient agricultural tool, but for centuries no one thought of eating with it. Not until the eleventh century, when a young lady from Constantinople brought her fork to Italy, did the custom reach Europe. By the fifteenth century the use of the fork was wide-spread in Italy. The English explanation was that Italians were unwilling to eat food touched with fingers, "seeing all men's fingers are not alike clean. Anyone who used a fork to eat with was laughed at in England for the next hundred years. Not until the late 1600's did using a fork become a common custom. The custom of eating with a fork was _ .
Choices:
A. brought to Europe from America
B. begun when forks first invented
C. brought to Europe from Constantinople
D. thought of by the Italians | C |

Global Positioning Systems (GPS) are now a part of everyday driving in many counties.These satellite-based systems provide turn-by-turn directions to help people get to where they want to go. But, they can also cause a lot of problems, send you to the wrong place or leave you completely lost. Many times, the driver is to blame. Sometimes a GPS error is responsible. Most often, says Barry Brown, it is a combination of the two. Barry Brown is with the Mobile Life Centre in Stockholm, Sweden. The center studies human-computer interaction, or HCI, especially communications involving wireless devices. He told us about an incident involving a friend who had flown to an airport in the eastern United States. There he borrowed a GPS-equipped car to use during his stay. "And they just plugged in an address and then set off to their destination. And, then it wasn't until they were driving for thirty minutes until they realized they actually put in a destination back on the West Coast where they lived. They actually put their home address in. So again, the GPS is kind of 'garbage in garbage out'." Mr. Brown says this is a common human error. But, he says, what makes the problem worse has to do with some of the shortcomings, or failures, of GPS equipment. "One problem with a lot of the GPS units is they have a very small screen and they just tell you the next turn. Because they just give you the next turn, sometimes that means that it is not really giving you the overview that you would need to know that it's going to the wrong place." The Mobile Life Centre in Sweden foruses on the research into _ .
Choices:
A. computer-computer interaction
B. human-computer interaction
C. satellite-satellite system
D. human-satellite system | B |
mmlu | Question:
The Post Office in Britain is famous for getting letters and parcels to places to which they should be sent. The problem is that we the public have to observe the rules. For example, we must put a stamp on a letter. If we don't, the receiver will have to pay double. We often see the sign ALL LETTERS MUST BE CORRECTLY ADDRESSED. These days, this means having to use postcodes. If you didn't use a postcode, it's no good complaining that your letter should have arrived sooner. Parcels are a problem because they must be correctly packaged. If Aunt Sophie is going to send you a jar of your favorite jam, she will have to wrap it up well. The most important thing we have to do is to address our letters and parcels legibly and correctly. This means clear handwriting and correct spelling. What we should do and what we actually do are often miles apart. Recently, the Post Office had to deliver a letter which showed a name followed by the word Arijaba. What is this, do you think? Arabic? Hiodustani ? Wrong both times! Say it out loud and you'll see it's just plain English. HARWICH HARBOUR! When we post parcels, we must _ .
Choices:
A. address them correctly
B. address them clearly
C. package them correctly
D. all of the above | D |

mmlu | Question:
A handsome man can earn a fifth more than an average-looking colleague but a beautiful woman is not paid a penny more than her average-looking colleague, new research has shown. The study by senior economists found that being good-looking meant male workers could earn 22 percent more than average-looking colleagues. Researchers said good looks did not give women a similar advantage. Andrew Leigh, a former economics professor at the Australian National University who co-authored the report, said: "Beauty can be a double-edged sword for women." "Some people still believe good looks and intelligence are incompatible in women, so a good-looking women can't be that productive, but it doesn't affect men's pay." He said that although he believed good-looking women may also earn more, the research did not support his theory. The research found that handsome men in all jobs, from manual labour to highly-paid professional careers, can earn 22 percent more than their colleagues doing the same work. Men with below-average looks face a battle in the office, with ugliness reducing a man's earnings by 26 percent compared to an average-looking worker. Former male model, Caitlan Mitchell, 28, who has a first class degree in history from Edinburgh University and now works for a cosmetics company, told theSunday Times:' It gives you confidence, and I suspect people tend to warm to you more quickly." The study, named Unpacking the Beauty Premium, was the largest exercise of its kind and repeated a survey from 1984 to see if the beauty premium had changed. Leigh said the research showed people in the workplace were "lookist "and he hoped the findings would encourage employers to remove their prejudice. What has the research found?
Choices:
A. Male workers pay more attention to their appearance.
B. Handsome men have an advantage in their jobs.
C. Appearance plays an important role at work.
D. The more beautiful a female is, the lower their intelligence is. | B |

mmlu | Question:
Findings from a new study were presented at a recent meeting of the American Psychosomatic Society. Researchers in the United States studied 100,000 women during an eight-year period, beginning in 1994. All of the women were fifty or older. The study was part of the Women's Health Initiative organized by the National Institutes of Health. The women were asked questions measuring their beliefs or ideas about the future. The researchers attempted to identify each woman's personality eight years after gathering the information. The study found that hopeful individuals were 14% less likely than other woman to have died from any cause. The hopeful women were also 30 less likely to have died from heart disease after the eight years, Hilary Tinkle from the University of Pittsburgh in Pennsylvania was the lead author of the report. She said the study confirmed earlier research that linked optimistic feelings to longer life. The researchers also gathered information about people's education, financial earnings, physical activity and use of alcohol or cigarettes. Independent of those things, the findings still showed that optimists had less of a chance of dying during the eight-year period. Some women who answered the questions were found to be hostile , or highly untrusting of others. These women were 16% more likely to die than the others. They also were 23% more likely to die of cancer. The study also found women who were not optimistic were more likely to smoke and have high blood pressure or diabetes. They were also more likely mot to exercise. Tindle says the study did not confirm whether optimism leads to healthier choices, or if it actually affects a person's physical health. She also says the study does not prove that negative emotions or distrust lead to bad health effects and shorter life. Yet there does appear to be a link that calls for more research. Researchers carry out the study to _ .
Choices:
A. decide who is more likely to enjoy a happier life.
B. gather information for the National Institutes of Health.
C. find out the link between personality and health.
D. compare each woman's personality changes. | C |
mmlu | Question:
After a day of work and play, the body needs to rest. Sleep is necessary for good health. During this time, the body recovers from the activities of the previous day. The rest that you get while sleeping enables your body to prepare itself for the next day. There are four levels of sleep, each being a little deeper than the one before. As you sleep, your muscles relax little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts back and forth from one level of sleep to the other. Although your mind slows down, from time to time you will dream. Scientists who study sleep state that when dreaming occurs your eyeballs begin to move quickly (although your eyelids are closed). This stage of sleep is called REM, which stands for rapid eye movement. If you have trouble falling asleep, some people recommend breathing very slowly and very deeply. Other people believe that drinking warm milk will help make you drowsy. There is also an old suggestion that counting sheep will put you to sleep. A good title for this passage is _ .
Choices:
A. Sleep.
B. Good Health
C. Dreams
D. Work and Rest | A |

Holding doors open, picking up rubbish, thanking people ... these acts of kindness seem very small. But students at Tibbett Middle School know that it's the small acts that make the world a better place. Eighth-graders from New Mexico, US, took part in the Random Acts of Kindness Week from Feb 10 to 14. During the week, they tried their best to do kind things for others, or for the environment. Celeste Murray, an English teacher at the school, started the activity. "I believe the world is changed by little things," she told the local newspaper. Over the week, Murray said she has seen changes in her class. Previously, she asked her students to push the chairs in after class. Now, the students do it by themselves. "The teachers will have less work," said Elisa Castaneda, one of Murray's students. Jordan Marshall, another eighth-grader, spent the week giving out praise . "It makes that person's day ," she said. "Besides helping others, the activity made students feel that they can make a difference," Murray said. Eighth-grader Haley Echols decided to continue to do at least one act of kindness every week. She believes her acts could encourage others. Random Acts of Kindness Week was started by _ .

Thomas Edison was one of ten said to be the greatest genius of his age. There are only a few men in all of the history, who have changed the lives of other men as much as the inventor of the first useful electric light. But Edison could never be happy only because someone said he was a genius." There is no such thing as genius," Edison said. He said that what people called genius was mostly hard work. But Edison was a dreamer as well as a worker. From his earliest days as a child he wondered about the secrets of nature. Nature, he often said, is full of secrets. He tried to understand them; then, he tried to learn what could usefully be done with them. Edison enjoyed thinking. He knew that most people will do almost anything instead of the difficult work of thinking, especially if they do not think very often. But he knew, too, that thinking can give men enjoyment and pleasure. Edison could not understand how anyone could be uninterested in life. As he loved to think, he also loved to work. On the day he became 75 years old, someone asked him what ideas he had about life. "Work," he answered. "Discovering the secrets of nature and using them to make men happier." He said he had enough inventions in his mind to give him another 100 years of work. Edison thought _ .

"Heaven is where the police are English, the cooks are French, the mechanics are German, the lovers are Italian and everything is organized by the Swiss. Hell is where the police are German, the cooks are English, the mechanics are French, the lovers are Swiss, and everything is organized by the Italians." Obviously the national stereotypes in this old joke are generalizations , but such stereotypes are often said to "exist for a reason". Is there actually a sliver of truth in them? Not likely, an international research team now says. "National and cultural stereotypes do play an important role in how people see themselves and others, and being aware that these are not dependable is a useful thing," said study author Robert McCrae of the National Institute on Aging. "These are in fact unfounded stereotypes. They don't come from looking around you," McCrae said. If national stereotypes aren't rooted in real experiences, then where do they come from? One possibility is that they reflect national values, which may become known from historical events. For example, many historians have argued that the spirit of American individualism has its origins in the experiences of the pioneers on the Old West. Social scientists such as psychologist Richard Robins have given several other possible explanations for stereotypes and why they may be incorrect. Robins notes that some stereotypes may have been correct at one point in history and then remained unchanged while the culture changed. We may be _ , to some degree, to keep incorrect stereotypes, since we are less likely to notice and remember information that is different from our stereotypes. Generally, according to Robins, when we meet people who are different from our stereotypes, we see them as unique individuals rather than typical national or cultural groups. National stereotypes are not always correct because _ .
Choices:
A. they are formed by individual historians
B. what was true in the past may not be true at the present
C. generalizations are made through personal experience
D. people tend to have false idea about other cultures | B |

My son was a second-grader. He went to school by bus every day. He was the first student on in the morning, as we were farthest from school, and the last student off in the evening. I was a teacher myself and it was a comfort to realize the school staff were all working as hard as I was to provide a safe learning environment. One day I came home from work and waited for my son to get home for a long time. Then I called the school. "Perhaps he's just a bit late," said the secretary. "I will call the driver to see if those children are home." A few minutes later, I answered the phone to hear that the other students were home. Then I called his friends' parents, to see if perhaps he had gotten off at their stop to play. The answers were all "No." By that time, it was dark and I was scared. My home was in the mountain areas, and it was said that a wolf had come up somewhere. My husband wasn't at home, so I forced myself to calm down and decided to go out to look for him. I was about to go out when the telephone rang; it was from the driver. "He's okay," I heard. "He was asleep on the seats in the back, under a couple of jackets. Since it's dark, can he spend the night with my family?" I was relieved and agreed. Since my son had a great adventure, the school started giving a copy of the list to the driver, so he could check off the children's names when they got off the bus. I think highly of the school for taking the cautionary step ahead; it is a sign of their concern for students, parents, and staff. The author's son probably spent the night _ .

A. in the bus
B. at his own home
C. at the driver's home
D. in the secretary's office | C |
mmlu | Question:
The English policeman has several nicknames but the most frequently used are "copper" and "bobby". The first name comes from the verb to "cop", meaning to "take" or "capture", and the second comes from the first name of Sir Robert Peel, the nineteenth-century politician, who was the founder of the police force as we know it today. An early nickname for the policeman was "peeler", but this one has died out. Whatever we may call them, the general opinion about the police seems to be a good one except, of course, among the criminal part of the community where the police are given more bad nicknames which came from America, such as "fuzz" or "pig". Visitors to prefix = st1 /Englandseem, nearly always, to be very impressed by the English police. It has, in fact, become a standing joke that the visitor toBritain, when asked for his views of the country, will always say, "I think your policemen are wonderful." Well, the British bobby may not always be wonderful but he is usually a very friendly and helpful sort of character. A music-hall song of some years ago was called, "If You Want To Know The Time, Ask A Policeman". Nowadays, most people own watches but they still seem to find plenty of other questions to ask the policemen. In London, the policemen spend so much of their time directing visitors about the city that one wonders how they ever find time to do anything else! Two things are noticeable to the stranger, when he sees an English policeman for the first time. The first is that he does not carry a gun and the second is that he wears a very special type of helmet . His helmet, together with his height, enables an English policeman to be seen from a long distance, a fact that is not without its usefulness. From time to time it is suggested that the policeman should be given a gun and that his helmet should be taken from him, but both these suggestions are not accepted by the majority of the public and the police themselves. In London, what do the policemen often do during their work-time nowadays?
Choices:
A. Direct anyone in the city
B. Tell others the time
C. Nothing
D. Show visitors the right way in the city | D |

As part of a comprehensive federal aid-to-education program, Congress included the following provisions as conditions for state receipt of federal funds: (1) Whenever textbooks are provided to students without charge, they must include no religious instruction and must be made available on the same terms to students in all public and private schools accredited by the state educational authority. (2) Salary supplements can be paid to teachers in public and private schools, up to 10 percent of existing salary schedules, where present compensation is less than the average salary for persons of comparable training and experience, provided that no such supplement is paid to any teacher who instructs in religious subjects. (3) Construction grants can be made toward the cost of physical plant at private colleges and universities, provided that no part of the grant is used for buildings in which instruction in religious subject matters is offered."Federal taxpayer Bates also challenges the construction grants to church-operated private colleges and universities. The most likely result is that the construction grants will be
Choices:
A. sustained, because aid to one aspect of an institution of higher education not shown to be pervasively sectarian does not necessarily free it to spend its other resources for religious purposes.
B. sustained, because bricks and mortar do not aid religion in a way forbidden by the establishment clause of the First Amendment.
C. held unconstitutional, because any financial aid to a church-operated school strengthens the religious purposes of the institution.
D. held unconstitutional, because the grants involve or cause an excessive entanglement with religion | A |

A study involving 8,500 teenagers from all social backgrounds found that most of them are ignorant when it comes to money. The findings, the first in a series of reports from NatWesl that has started a five-year research project into teenagers and money, are particularly worrying as this generation of young people is likely to be burdened with greater debts than any before. Universitytuition fees are currently capped at PS3,000 annually, but this will be reviewed next year and the Government is under enormous pressure to _ In the research, the teenagers were presented with die terms of four different loans but 76 per cent failed to identify the cheapest. The young people also predicted that they would be earning on average PS 31.000 by the age of 25, although the average salary for those aged 22 to 29 is just PS 17,815. The teenagers expected to be in debt when they finished university or training, although half said that they assumed the debts would be less than PS 10.000. Average debts for graduates are PS 12,363. Stephen Moir, head of community investment at the Royal Bank of Scotland Group which owns NatWest, said. "The more exposed young people are to financial issues, and the younger they become aware of them, the more likely they are to become responsible, forward-planning adults who manage their finances confidently and effectively." Ministers are deeply concerned about the financial pressures on teenagers and young people because of student loans and rising housing costs. They have just introduced new lessons in how to manage debts. Nikki Fairweather aged 15 from St Helens, said that she had benefited from lessons on personal finance, but admitted that she still had a lot to learn about money. What can we learn from the passage?
Choices:
A. Many British teenagers do not know money matters well
B. Teenagers in Britain are heavily burdened with debts.
C. Financial planning is a required course at college.
D. Young people should become responsible adults. | A |
mmlu | Question:
Everyone hates to wait in lines. We get that anxious feeling that our precious life is slipping away while we're doing something so meaningless. But it's not always the length of the wait we find so unbearable. Some people camp outside Apple stores for an entire night just to get their hands on the latest product. But waiting 10 minutes in a grocery store just to buy a drink? Forget it. Our behavior when waiting is only partly decided by the length of the wait. "Often the psychology of queuing is more important than the statistics of the wait itself," notes the MIT researcher Richard Larson. One apparent aspect of queuing psychology is that we get bored when we wait in line. This issue is solved in many ways, from magazines in hospital waiting rooms to mirrors in elevators so that we can check our appearance. We really hate it when we expect a short wait and then get a long one. But studies show that we are much more patient when we are given an idea of how long we'll be waiting. Walt Disney Co knows this better than anyone else. It posts estimated waiting times for attractions in its theme parks. But according to Larson, these times are overestimated so that visitors get to the front of the queue more quickly than they expect. It keeps them happy. But perhaps the biggest influence on our feelings about waiting in a line has to do with our sense of fairness. When it comes to queues, the universally acknowledged standard is first come, first served. Any departure from this principle is regarded as unfair and can lead to violent queue anger. You've probably experienced mild queue anger yourself in fast food restaurants, watching people in the other line zoom ahead of you, cursing yourself for having chosen the "wrong" line. In order to solve this problem, the serpentine line was invented. The serpentine line guides all customers into one big snaking queue, separated by ropes or barriers. When you reach the head of the queue, you are directed to the next available server, or teller, or customs official. The serpentine line isn't always faster than multi-lines before an array of cash registers. But it offers important comfort: you absolutely never have to see someone arrive after you and get served before you. In life, waiting is inevitable. But a better understanding of the psychology of waiting can help make it a bit more bearable. When all else fails, bring a book or a smart phone will also do. The main purpose of the passage is _ .
Choices:
A. to explain the advantages of serpentine line
B. to introduce ways of saving time in queuing
C. to offer an explanation of the psychology of queuing
D. to analyze the psychology of people queuing for Apple products | C |

Lombard Street (San Francisco, USA) Known as "the world's most-crooked street," Lombard Street was first built in 1922 to reduce the hill's natural 27 % grade ,which was too steep for most vehicles. Lombard Street owns the record as the street with the most switchbacks in a single block. With eight steep and sharp turns, Lombard Street looks like a giant dizzy snake lying on the road. This famous street in San Francisco is known as the most-challenging street of all. Parliament Street (Exeter, England) This street in England is over a hundred years old today, but what makes it as an urban wonder is not its age but its unbelievable narrow size. Usually, a street is where a vehicle can conveniently pass, but that will never happen in the Parliament Street, as the street measures just 25 inches wide which is just enough for a ly medium-built person to pass. King Fahd's Fountain (Jeddah, Saudi Arabia) The fountain was donated to the city by King Fahd. Being the world's tallest fountain, it deserves to be an urban wonder. It was constructed between 1980 and 1983. This fountain shoots water in an incredible 1023-foot (312m) height which is greater than the height of the Eifel Tower. Because of its seemingly unreachable height, the waters of the King Fahd's Fountain can be sighted even if the visitors are miles apart. Damanhur Temple (Northern Alps of Italy) The underground of the modest homes of Italy's northern Alps is where a massive, richly -decorated temple is found. The Damanhur Temple was secretly constructed in the 1970s. Decorated with impressive murals and vividly-color1ed stain glass, the temple was once seized by the Italian government due to illegalities. After some time, it was returned to Oberto Airaudi, the builder and founder of Damanhur. Why was Lombard Street built that way?
Choices:
A. To ease the traffic.
B. To challenge citizens.
C. To attract visitors.
D. To set a record. | A |
mmlu | Question:
When I walk through the streets, I pass strange rooms where people are doing strange things. Some are biking madly. Others are holding metal bars to keep them from dropping down. Still others are jumping around while someone is shouting at them. It looks like something out of Dante's Inferno (<<>> <<>> ). But what is the most amazing is that people pay for these sufferings! The strange rooms are gyms. It is reported that some 41 million Americans are gym members. 12% of the memberships are born in January, as they are determined to knock off the holiday fat. Maybe it is good to exercise in the gym. However, should they know they can keep in good shape, spending little money, would they still agree with its necessity? At the age of 23, I joined a gym. I lifted weights twice a week in Muscle's Gym. I paid as little as $200 per year. You can't find such gyms in every city any more. Too often, the gym is fancy with lots of equipment. If you ask how much it costs to join it, the person at the front desk often won't tell you straight. Instead, he'll let you meet with a fitness consultant , who will provide you with a great number of reasons and suggestions, such as losing weight and getting healthier, just in order to put pressure on you to spend much money joining the gym and becoming a member there. Working out with the help of equipment at home has problems, too. In the early 2000's, I bought a spinning bike at a cost of $700 for home use. I tried a few times only to find that it brought me a neck problem. Now I'm back to my old way. I do Yoga every morning and evening. Total cost: $60 for an exercise mat . I'm enjoying fitness. From the text we can infer that _ .
Choices:
A. many Americans put on weight after Christmas and New Year's Day

Many young people want to become pop-stars. It is their great ambition in life. They think pop-stars earn a lot of money, they lead interesting and exciting lives, thousands of fans love them, and they become famous! Yes, but first they must become stars. Most performers star life with a group. This is the pattern nowadays. But there are many groups and competitions are hard. Groups appear and disappear almost overnight. Only a small number survive. Almost without exception they have to work very hard before they reach the top. And very few reach the top and stay there. In England there are perhaps thirty or so groups at the top.

He is the key person in their lives and takes about 20% of their earnings-perhaps more. Then there are their clothes, their instruments and their van. Sometimes they are still playing for the last two items. And don't forget, they have to travel a great deal-sometimes 2,000 miles in one week. At times they even sleep in their van instead of a hotel, just to save money. So now, what do you think? Are pop-stars so rich? And do they have such exciting lives?

mmlu | Question:
Today, bicycles are elegantly simple machines that are common around the world. Many people ride bicycles for recreation, whereas others use them as a means of transportation. The first bicycle was invented in Germany in 1818. Because it was made of wood, it wasn't very strong nor did it have pedals .Riders moved it by pushing their feet against the ground. In 1839, Kirkpatrick Macmillan, a Scottish blacksmith, invented a much better bicycle. Macmillan's machine had iron-covered wheels to keep them from getting worn down. He also used foot-operated levers, similar to pedals, so his bicycle could be ridden at a quick pace. It didn't look much like the modem bicycle, though, because its back wheel was substantially larger than its front wheel. Although Macmillan's bicycles could be ridden easily, they were never produced in large numbers. In 1861, Frenchman Pierre Michaux and his brother Ernest invented a bicycle with an improved pedal mechanism. They called their bicycle a velocipede,but most people called it a "bone shaker" because of the effect of the wood and iron frame. Despite the impolite nickname, the velocipede was a hit. After a few years, the Michaux family was making hundreds of the machines annually, mostly for fun-seeking young people. Ten years later, James Starley , an English inventor, made several innovations that revolutionized bicycle design. He made the front wheel many times larger than the back wheel, put a gear on the pedals to make the bicycle more efficient,and lightened the wheels by using wire spokes. Although this bicycle was much lighter and less tiring to ride, it was still clumsy, extremely top-heavy,and ridden mostly for entertainment. It wasn't until 1874 that the first truly modern bicycle appeared on the scene. Invented by another Englishman, H. J. Lawson, the safety bicycle would look familiar to today's cyclists. The safety bicycle had equal-sized wheels, which made it easier to ride. Lawson also attached a chain to the pedals to drive the back wheel. By 1893,the safety bicycle had been further improved with air-filled rubber tires, a diamond-shaped frame, and easy braking. With the improvements provided by Lawson;bicycles became extremely popular and useful for transportation. Today, they are built, used, and enjoyed all over the world. The information about bicycles in this passage is arranged according to _ .
Choices:
A. importance
B. time
C. place
D. Interest | B |
mmlu | Question:
As you climb into the hill country, the roads get dustier and rougher, and fewer cars can be seen. Phonxay is one of the poorest districts of Laos, and many of its villages are only accessible by footpath. Our destination this hot morning is a concrete water tank that can be found just off the road. A UK organization helped to build it six years ago, and in the nearby village of Thapho, where clean drinking water is scarce, it has made a big difference. The tank feeds six taps which in turn give water to over 800 people---it has improved things for almost every family, from schoolchildren to grannies. But lately, we were told, the clean water supply has come under pressure from new arrivals, people who have come down from the hill areas, and there are concerns that there will not be enough clean water to go round. There are also serious worries about resources in Laos. The Chinese are building a 400km railway link, which could transform the landlocked country. About 150,000 Chinese workers will be involved. What will this do to local clean water supplies? How will the workers be fed? The vast majority of Laotians live on farms. But with foreign investors wanting to buy up land, local people will have to be moved to make room for them. Heavily dependent on both foreign aid and foreign investment, Laos still falls well behind its neighbours, although its economy has grown at about 6% a year in the last decade. Its biggest economic problem is the lack of locally trained skilled workforce. But there are reasons to be hopeful for the future. Laos is beautiful, and foreign tourism continues to grow: fortunately so far the fast-food chains and coffee bars common elsewhere are nowhere to be seen. Although all local media are government-run, the Internet is not controlled and the BBC and CNN are available to those with satellite dishes. The government has also achieved impressive results in rural development, with communities benefiting not just from cleaner water but the construction of new schools and regular visits from medical teams. Poverty will not be history in Laos within the next decade, but with small steps forward and a bit of outside help, the country could find itself out of the UN's least-developed category by 2020. What is the best title for the passage?
Choices:
A. Laos: slow-developing nations
B. Laos: small steps forward
C. Laos: least-developed land
D. Laos: landlocked country | B |

mmlu | Question:
When I was a child, our dining room had two kinds of chairs--two large ones with arm rests and four small ones without. The larger ones stood at the ends of the table, the smaller ones on the sides. Mom and Dad sat in the big chairs, except when one of us was away; then Mom would sit in one of the smaller chairs. Dad always sat at the end, at the "head" of the table. Sitting where he did, Dad was framed by the window through which the yard could be seen with its trees and grass. His chair was not just a place for him at the table; it was a place in which he was situated against the yard and trees. It was the holy and protected place that was his, and ours through him. After Dad retired, he and Mom moved out into a small flat. When they came to visit me at their old house. Dad still sat at the end of the table though the table was no longer his but mine. Only with my marriage to Barbara, did I hear a voice questioning the arrangement. She requested, gently but firmly, that I sit at the head of the table in our home. I realized then that I was head of the family, but I also felt unwilling to introduce such a change. How would I feel sitting in that "head" place in my Dad's presence? And how would he handle it? I was to find out on the occasion of our youngest child's first birthday. Mom and Dad arrived for lunch, and went into the dining room. Dad moved toward his usual seat in front of the window. Before he could get around the side of the table, I took a deep breath and said, "Dad, this is going to be your place, next to Mom, on the side." He stopped, looked at me and then sat down. I felt sad, and angry at Barbara for pushing me to do this. It would have been easy to say, "My mistake, Dad. Sit where you always sit." But I didn't. When he and Mom were seated, Barbara and I took our places. I don't know how Dad felt. I do know that, though removed from his usual place, he continued to share his best self with us, telling stories of his childhood and youth to the delight of his grandchildren. As I served the food, our lives experienced a change, which we continue to live with. It wasn't easy, but I sense that there is also something good in the change which has occurred. I am beginning to learn that "honoring one's father" is more than the question of which place to occupy at the dining table. It also means listening, wherever we sit and whatever positions we own, to the stories Dad longs to tell. We may then, during these magical moments, even be able to forget about whose chair is whose. What did the writer learn about "honoring one's father"?
Choices:
A. Fathers always long to tell stories about their early years.
B. Providing the fight chair is the only way to honor one's father.
C. Respect for one's father doesn't depend only on where he sits.
D. The family should dine together at the same table as often as possible. | C |
mmlu | Question:
Spending as little as $5 a day on someone else could significantly _ happiness, the team at the University of British Columbia found. Their experiments on more than 630 Americans showed they were measurably happier when they spent money on others even if they thought spending the money on themselves would make them happier. "We wanted to test our theory that how people spend their money is at least as important as how much money they earn," said Elizabeth Dunn, a psychologist at the University of British Columbia. They asked their 600 volunteers first to rate their general happiness, report their annual income and detail their monthly spending including bills, gifts for themselves, gifts for others and donations to charity. "No matter how much income each person made, those who spent money on others reported greater happiness, while those who spent more on themselves did not," Dunn said in a statement. Dunn's team also surveyed 16 employees at a company in Boston before and after they received an annual profit-sharing bonus of between $3,000 and $8,000. "Employees who devoted more of their bonus to prosocial spending experienced greater happiness after receiving the bonus, and the manner in which they spent that bonus was a more important predictor of their happiness than the size of the bonus itself," they wrote in their report, published in the journal Science. They gave their volunteers $5 or $20 and half got clear instructions on how to spend it. Those who spent the money on someone or something else reported feeling happier about it. "These findings suggest that very minor changes in spending allocations-as little as $5 may be enough to produce real gains in happiness on a given day," Dunn said. Which of the following statements is NOT true according to the passage?
Choices:
A. Those who spend more money on others can get much more bonus.
B. People usually think spending money on themselves will make them happier.
C. Very small changes in spending your money may be enough to gain happiness.
D. Researchers think that how people spend their money is at least as important as how much money they earn. | A |

We drink tea every day. But more than three hundred years ago most of the people in Europe did not know anything about tea. Some people heard about it, but very few of them know what to do with it. There is a story about an English sailor who went to countries in the east, the west and the south. He went to India and China. One day he came home and brought some tea as a present for his mother. She told her friends about the present and asked them to a "tea party". When her friends came to the "tea party", the old woman gave them brown tea-leaves. The old woman's friends began to eat them. Of course, nobody liked the tea-leaves. At that time the sailor came in. He looked at the table and said, "Mother,what did you do with the tea?" "I boiled it,as you said."

As we all know , the language is a very important tool for people to communicate with each other. In most of the languages , people usually begin their conversations by a kind of small talk -a casual form of conversation that "breaks the ice" or fills an awkward silence between people . That is to say , small talk means the little things we talk about to start a conversation . In English-speaking countries such as Britain, people often make small talk about the weather. " Nice day, isn't it?" "Terrible weather , isn't it?" However, we still have something special about small talk. It must be about something which both people have the same opinion about. The purpose of small talk is to let both people agree on something. This makes meeting people easier and more comfortable . People usually agree about the weather, so it is a safe topic for small talk. But people often disagree about religion or politics so these are not suitable topics for small talk. The topics for small talk also depend on where the conversation is taking place. At basketball matches, people make small talk about the game they are watching. "Great game , isn't it?" At train stations, people may talk about the transport system . " The train service is terrible, isn't it?" What is the favorite topic of small talk for English people ?

A. the languages

C. the game

For any person who must speak in public, to business or pleasure groups, humor is a helpful, and necessary, tool for getting your message across. Why does humor work a lot? There are several reasons. People will enjoy what you have to say if it is presented with humor. But, more importantly, if you are in a situation where important, and perhaps controversial , ideas must be presented to less than open minds, humor allows those ideas to be presented in a non-threatening manner. Abraham Lincoln was famous for his ability to relate humorous stories to make a point. Humor used carefully throughout a presentation will also keep the listener's interest high. In a word, individuals learning how to use humor in their speeches can strengthen arguments, support interesting presentations and, most of all, entertain their audience in a positive and comfortable way. While popular culture may well hold many kinds of humor, some of it has no place in presentations that are designed to educate and encourage the audience. If you want to become a professional stand-up comedian whose goal is 100% entertainment, then you may be able to use some of the reference materials like The Art of Using Humor in Public Speaking. They can help you develop your skills and sources of humor. To that _ , your participation in this study of humor will become necessary. Hopefully, you will come to appreciate the special difficulty of entertaining the audience with good and clean humor. The passage is most likely to benefit _ a lot.

Reading is not the only way to gain knowledge of the work in the past. There is another large reservoir which may be called experience, and the college students will find that every craftsman has something he can teach and will generally teach gladly to any college student who does not look down upon them. The information from them differs from that in textbooks and papers chiefly in that its theoretical part -- the explanations of why things happen -- is frequently quite fantastic . But the demonstration and report of what happens, and how it happens are correct even if the reports are in completely unscientific terms. Presently the college students will learn, in this case also, what to accept and what to reject. One important thing for a college student to remember is that if Aristotle could talk to the fisherman, so can he. Another source of knowledge is the vast store of traditional practices handed down from father to son , or mother to daughter, of old country customs ,of folklore . All this is very difficult for a college student to examine, for much knowledge and personal experience is needed here to separate good plants from wild grass.The college students should learn to realize and remember how much of real value science has found in _ and how often scientific discoveries of what had existed in this area long age.

Laughter Yoga is a unique technique invented by Dr Kataria, a doctor from India, by which you can learn to "Laugh for No Reason". You don't even need a sense of humor, no funny jokes or comedy programs -- just a willingness to laugh -- and in the present climate everyone needs to laugh more. Laughter Yoga is a combination of Laughter Exercises and Yogic Breathing, so that you increase the amount of oxygen in your body while being playful, resulting in you feeling healthier, energetic and alive. This actually changes the physical conditions of your body so that you start to feel happier. Laughter Yoga is generally done in groups although it can be practiced alone. When you make eye contact with someone and you're both willing to laugh, the laughter is increased. However, we do say that you can "Fake it, fake it till you make it" because the body doesn't know the difference between fake and true laughter; as long as you're willing to laugh you'll experience the same health benefits. Laughter Yoga started in a park in Mumbai in 1995 with just 5 participants, and now there're over 6,000 laughter clubs in 60 different countries -- showing the willingness of the world to laugh together. In the UK, Julie was one of the first people to train as a Laughter Leader with Dr Kataria in June 2002. In 2006 she was awarded Laughter Ambassador for her selfless service to promote Laughter Yoga. "Yoga has been part of my life for 30 years but 7 years ago my life changed when I discovered Laughter Yoga. I believe laughter and yoga are both good for your health," says Julie. The purpose of the passage is to _ .

It's always great to hear news about wildlife returning to where they once lived. For the first time in 8 years the small blue --- British's smallest butterfly--- has been seen back at a nature reserve in Hertfordshire. This nature reserve has had a lot of work done recently in order to help butterflies. Management of the land has included bringing in sheep to keep the grass under control in a more natural way and planting wild flowers for butterfly species. The nature reserve is home to a number of butterfly species. In fact the way that this reserve has been managed means that it is probably the best reserve in Hertfordshire to see butterflies with at least 25 species now living in the area. There are a number of threats to British butterflies and the greatest threat is the loss of their habitat. Changing farming practice has affected British native butterfly species greatly with many more now being at risk. _ A wide species of butterflies will generally mean a healthy environment. The type of land management at the nature reserve in Hertfordshire offers a hope for many species of butterfly to live as usual. Butterflies need all the help they can get at the moment. Although the number of butterflies is beginning to increase, many are still at risk. Why did the butterflies fly away eight years ago?

parents usually go to malls to find new school supplies for their children. One of the most important things to get during this time is the backpack. Most students choose to bring a backpack because it allows them to have both hands free. This makes the bag less likely to hinder other activities that the person carrying it may be doing at the same time. Here are the ways parents can choose the perfect backpack for school. How many books will children be carrying to school? How many notebooks should be inside the bag? Parents should know these details before buying a bag for their children. Each situation requires a different bag so it pays to ask children about the expected load. Do children need special storage for the bag? If they will be carrying a laptop computer inside the new backpack,make sure that parents get a model that's designed specifically for laptop use. This will protect the computer from bumps and falls that might damage the device if it had less protection. Are children going to use the bag for a long time? If they want to use a bag for a long time,parents will be better off investing in a good brand that is known for quality. Parents may have to pay extra cash to get the top of the line and the best backpack in the market.[:## Count the pockets.

Looking through a magazine in a waiting room recently, I came across an article with the title "My top five most precious possessions".It was just a few lines of text with pictures, but it caught my imagination. It's interesting how inanimate objects can take on such significance and become woven into a person's, and sometimes a whole family's life history. Anyway, the article had me considering what my most precious possessions are. It was difficult to choose only five, but here are mine: An old cardboard box filled with my children's baby photos. A yellow pocketsized birthday book of special things (poems, pictures of flowers and trees, etc) given to me by my dad when I was probably about seven or eight years old. A 21st Birthday card from my mum. In it she's written her congratulations, her love, and her hopes for my future. She died not long after, when I was in my early twenties. A few ancient but very beautiful botany books that were once my great grandmother's. She was a botanist in a time when it was ly unusual for women to be qualified in this field and I think she was probably a remarkable and very interesting woman. I'd like to have known her. A brooch left to me by my muchloved grandmother. It was given to my great grandmother (her mother) by my great grandfather on his return from World War I. It is not worth anything in terms of money. However, it not only stands for a link between four generations of women, but it is also a reminder of one young man's return from World War I. How about you? I'd love to hear what you feel are your most precious possessions. According to the passage, the writer _ .

Millions of young people are writing blogs . Millions of others are reading them. The word "blog" is a short way of saying Web log. Many popular Web sites now offer free, easy ways to create personal Web pages and fill them with writings and pictures. Web sites called "Face book" and "My Space" are some of the most popular blog sites for young people. Blogs offer young people a place to show their writings and feelings.

The Hunan Satellite TV(HNTV) show "Where are we going, Dad?" is a big hit. Many famous stars brought their children to a strange village alone, and they had to spend 72 hours with their children there. The program fully showed us a modern version of the "how to be a good father". As the young parents today are too busy to take care of their children, this new form of "Lost on the way" played by nanny Daddy and cute kids triggered a lot of people's emotional resonance . Both the kids and their parents will find that their hearts are being drawn closer. But this kind of feeling has just proved that there is a big spiritual barrier between the modern parents and children. The TV shows like "Children are hard to support!", "Where are we going, Dad?", "hot mom" and "cute kids" are becoming more and more popular. All of these show the new parents' confusion in children's education and the appeal for the balance between career and family. In real life, on the one hand the young parents feel helpless because they are too busy to accompany their children under the pressures of work and life; on the other hand they continue to do so. The data collected by HNTV shows that nearly two-thirds of their audience are female, among whom 36% are aged from 25 to 34. We can imagine such a scene that one evening a young mother is watching the show with her young children, while her husband is still at work or trapped in socializing, or maybe is just playing computer games in the bedroom. The story of a child without the company of father is still going on. In fact, it is sometimes the same to mothers. In a modern family, it is often the old who take the responsibility of raising a child. The participation of mother in the children's education is also very low. It is just this kind of confusion where the parents have gone in the modern family education, and where the parents will guide their children to go that "Where are we going,Dad?" shows us. If a child wants to grow up healthily and safely into a modern citizen with independent personality and free spirit, it is very important for him or her to follow the parents who serve as their first teacher. Maybe this is the real reason why such kind of TV programs could get hot. The truth is that children will go where their parents go; and society will go where the children go. Which one is the best title of the passage?
Choices:
A. Nanny Daddy and Cute Kids
B. Modern Education is Important
C. Confusion Behind "Where are we going, dad?"
D. New Problems in Modern Children's Education | C |

Losing weight comes with a lot of health benefits--including making your brain sharper. Yes, it turns out that overweight may damage cognitive functions such as memory and attention. There have been few studies of overweight and cognitive functioning, possibly because it is generally believed that it is not a primary risk cause for poor cognitive performance. Losing weight, therefore, may help improve these mental functions, according to a new research led by John Gunstad, assistant professor of psychology at Kent State University. Growing evidence suggests that being fat is linked to cognitive deficits . So Gunstad and his team guessed that losing weight might improve mental function. For their study, they measured memory and attention in a group of 150 overweight participants, some of whom had some kind of operation for weight loss and some did not. All of the volunteers completed mental skills tests to assess their abilities of memory and attention at the beginning of the study, and again 12 weeks later. To begin with, about 24% of the patients showed damaged learning and 23% showed signs of poor memory when tested. At the end of the study, those who had lost weight after operation improved their scores into the average or above average range for cognitive functions. Scores for the volunteers who didn't lose weight dropped even further. The study helped Gunstad to find out whether losing weight had any effect on mental function. Now that he's seen the positive effect that weight loss can have on memory and attention, he says he will next study those who choose to lose weight by the traditional way--eating healthier and getting more active. He expects that losing weight in this way will have a similarly positive effect on the brain. "If we can improve the condition with operations, then we can probably produce the same change with behavioral weight loss as well," he says. What is Gunstad planning to prove next in his research?
Choices:
A. Slim people are smarter than overweight people.
B. Healthy diet is better than exercise in losing weight.
C. Traditional ways of losing weight are better than operation.
D. Overweight people will get smarter by taking more exercise. | D |

mmlu | Question:
Napoleon Bonaparte died on May 5, 1821, on the island of St. Helena off the coast of Africa. He was 51 years old at the time. When doctors examined Napoleon's body, they said that the former emperor of France had died from cancer of the stomach. That was the cause of death recorded in the official report. However, other doctors disagreed. One doctor who was present during the examination of the body said that Napoleon died of hepatitis. Other historians and medical experts have suggested that Napoleon died of syphilis, tuberculosis, or perhaps malaria. Now, after careful research, a British chemist thinks that Napoleon might have been poisoned -- not by a person, but by his wallpaper. Napoleon was sent to the island of St. Helena in 1815 after he lost the battle of Waterloo. He was a prisoner on the island. Although he had servants to attend to him, he had to live in one small building. St. Helena is a very wet island, so the walls of the building were always covered with mold. Napoleon became ill from spending too much time inside his house. Almost constantly he had a fever, chills, and felt sick to his stomach. He often felt pain in his shoulders and in his side. His skin turned yellow. He got frequent headaches, and he would become dizzy and vomit . None of the medicine that the doctors gave Napoleon seemed to help. They were not sure what was the matter. Finally, Napoleon was too weak to leave the house. One night, while he was sleeping, he went into a coma and died. Many doctors who later reviewed the reports of Napoleon's illness found that the symptoms did not show a man who suffered from stomach cancer. It seemed obvious that Napoleon had died from some other cause. In 1961, a Swedish doctor examined some of Napoleon's hair and found a high level of arsenic, a chemical poison. Was Napoleon murdered? It is doubtful. Arsenic was used in many types of medicine during Napoleon's time, so he might have taken the arsenic as a cure for his illness. Then, in 1982, Dr. David Jones from England began to look into the mystery and suggested that Napoleon might have breathed in arsenic which was in the air of his house. In the 1700s and 1800s, arsenic was used to make a kind of green paint used on cloth and wallpaper. If the paint was used on a wet wall, the arsenic would go into the air. A person in the room might breathe that air. After studying the wallpaper in the room where Napoleon died, Dr. Jones found high levels of arsenic in the green paint on the walls. Why did Napoleon live on St. Helena?
Choices:
A. He owned the island.
B. He was a prisoner there.
C. His family lived there.
D. He liked the island. | B |

Adam's car sustained moderate damage in a collision with a car driven by Basher. The accident was caused solely by Basher's negligence. Adam's car was still drivable after the accident. Examining the car the next morning, Adam could see that a rear fender had to be replaced. He also noticed that gasoline had dripped onto the garage floor. The collision had caused a small leak in the gasoline tank. Adam then took the car to Mechanic, who owns and operates a body shop, and arranged with Mechanic to repair the damage. During their discussion Adam neglected to mention the gasoline leakage. Thereafter, while Mechanic was loosening some of the damaged material with a hammer, he caused a spark, igniting vapor and gasoline that had leaked from the fuel tank. Mechanic was severely burned. Mechanic has brought an action to recover damages against Adam and Basher. The jurisdiction has adopted a pure comparative negligence rule in place of the traditional common-law rule of contributory negligence. In this action, will Mechanic obtain a judgment against Basher?
Choices:
A. No, unless there is evidence that Basher was aware of the gasoline leak.
B. No, if Mechanic would not have been harmed had Adam warned him about the gasoline leak.
C. Yes, unless Mechanic was negligent in not discovering the gasoline leak himself.
D. Yes, if Mechanic's injury was a proximate consequence of Basher's negligent driving. | D |

mmlu | Question:
People in the United States honor their parents with two special days: Mother's Day, on the second Sunday in May, and Father's Day, on the third Sunday in June. Mother's Day was proclaimed a day for national observance by President Woodrow Wilson in 1915. Ann Jarvis from Grafton, West Virginia, had started the idea to have a day to honor mothers. She was the one who chose the second Sunday in May and also began the custom of wearing a carnation. In 1909, Mrs. Dodd from Spokane, Washington, thought of the idea of a day to honor fathers. She wanted to honor her own father, William Smart. After her mother died, he had the responsibility of raising a family of five sons and a daughter. In 1910, the first Father's Day was observed in Spokane. Senator Margaret Chase Smith helped to establish Father's Day as a national commemorative day, in 1972. These days are set aside to show love and respect for parents. They raise their children and educate them to be responsible citizens. They give love and care. These two special days are celebrated in many different ways. On Mother's Day people wear carnations. A red one symbolizes a living mother. A white one shows that the mother is dead.Many people attend religious services to honor parents. It is also a day when people whose parents are dead visit the cemetery. On these days families get together at home, as well as in restaurants. They often have outdoor barbecues for Father's Day. These are days of fun and good feelings and memories. The author's purpose of writing this passage is to _

On Easter Day, 1722, Dutch explorers landed on Easter Island . It was the first time that Easter Islanders had met people from the outside world. The strangers were about to discover something very strange themselves --that they were on an island with hundreds of huge stone statues . The Dutch explorers wondered where the Islanders had come from and why and how they had built the statues. Now science is putting together the story. The first people to arrive on the island came there around A.D. 700. The society that developed there was based on fishing and farming to feed the population, which grew to 12,000. Its success showed itself in a way that has become the island's trademark : hundreds of huge stone figures --the moai. None of the moai was standing when scientists first arrived. People put them back up later; but how had a Stone Age society ever made, moved and set them up there in the first place? And why? There are nearly 900 moai on Easter Island, and while the questions about them remain unanswered, no one doubts the years of effort that must have gone into making them. The real killer of the Easter Islanders came from across the ocean. After 1722, it became popular for explorers to visit Easter Island, bringing diseases. The final blow came in 1862, when slave traders came from Peru and took away 1,500 people, one-third of the population. Before the Dutch explorers arrived on Easter Island, _ .

When a tornado hit the small town of Otwell, Indiana years ago, Kathryn Martin, 32, who lived 60 miles away in Evansville, couldn't get the news out of her mind. "I kept thinking, 'Those poor people. Somebody's got to help them,'" she says. She knew firsthand what they were going through. Six months earlier, a tornado had struck her town, taking the lives of her 2-year-old son, C.J. and her mother-in-law. "It was the most terrible experience of my life," she says. "That _ will never go away, and it broke my heart to think about what these families were going through in Otwell." So Kathryn loaded her car with juice boxes, snacks and toys and drove to Otwell. She gave the items to the Red Cross, and as she was leaving, she saw a couple sorting through the ruins of their home while their children were watching. So Kathryn stopped and gave a few toys to the kids and played with them for a while. "The parents couldn't thank me enough for what I did for their children," she says. On the drive back to Evansville, Kathryn came up with an idea to help more kids. She talked her family, friends and neighbors into joining her and spent the next few months organizing fundraisers. Finally, in August 2007, she showed C.J.'s Bus, a 35-foot school bus that was turned into a mobile playroom. In the following years, stocked with video games and DVDs, toys, crafts, books and more, the bus traveled to disaster-torn towns, giving the children there a safe place to play. So far, C.J.'s bus has traveled to three states affected by tornadoes or floods, cheering up more than 756 children, aged 3-13. What do we know about C.J.'s Bus?

mmlu | Question:
"Community" is not a concept that is easy to define . In this essay I will examine what turns individuals into a community, and discuss some different types. I will also look at what all communities have in common, the benefits they offer and draw conclusions about their increasing importance. The word "community" may make you think of traditional communities in the developing world, where large families live together. We may also imagine the neighbours as people who are happy to help out whenever it is needed. The stereotypical view is that of a village, where people have little but can feel very rich because everyone takes responsibility for the welfare of the others. On the other hand, there are other types of communities: ultramodern ones, where the community members are unlikely to have actually met each other. These are online communities, where people blog or chat about particular issues that are important to them. They come across others on websites and may develop a relationship there with like-minded people, discussing the same topics. The view is often that these are artificial connections between people who are, in fact, still isolated strangers. In reality, the connections are real. Moreover, there are many types of communities in between these extremes: people who join clubs, who sign up with voluntary, political or other organizations, or who take part in group discussions in their local area. They may be campaigning about issues or simply getting together for companionship and support. Human beings are social by nature, so it should not be a surprise that we organize ourselves in groups. However, there is more going on: these groups provide something that we cannot achieve on our own. The main benefit of being part of a larger group is strength in numbers. For example, we can access and share more information, we can take part in team sports, we can complain and campaign more effectively and even if we are just having a chat, online or in person, we can feel supported in whatever we do. Whatever forms communities take, what defines them is the sense of identity and safety that they provide for their members: the knowledge that there are people who we have something in common with and who can be relied on when we need each other. In traditional communities, people _ .
Choices:
A. live in a large family
B. are wealthy but unhappy
C. are isolated and don't have connections
D. help and care about each other | D |

Expert say that students usually need eight to ten hours' sleep at night, but most Chinese students do not get enough sleep. Some Chinese parents are usually glad to see their children studying late. They will think their children work very hard, but not all parents are happy about this. Once a mother told us tat every morning her 10-year-old boy put up one finger with his eyes still closed, begging for one more minute to sleep.

Brown suffered from the delusion that he was a special agent of God. He frequently experienced hallucinations in the form of hearing divine commands. Brown believed God told him several times that the local Roman Catholic bishop was corrupting the diocese into heresy, and that the bishop should be "done away with." Brown, a devout Catholic, conceived of himself as a religious martyr. He knew that shooting bishops for heresy is against the criminal law. He nevertheless carefully planned how he might kill the bishop. One evening Brown shot the bishop, who was then taken to the hospital where he died two weeks later. Brown told the police he assumed the institutions of society would support the ecclesiastical hierarchy and he expected to be persecuted for his God-inspired actions. Psychiatrist Stevens examined Brown and found that Brown suffered from schizophrenic psychosis, that in the absence of this psychosis, he would not have shot the bishop, and that because of the psychosis, Brown found it extremely difficult to determine whether he should obey the specific command that he do away with the bishop or the general commandment "Thou shalt not kill." Brown was charged with murder. If Brown interposes an insanity defense and the jurisdiction in which he is tried has adopted only the M'Naghten test of insanity, then the strongest argument for the defense under that test is that

IKEA is the world's largest furniture retailer, and the man behind it is Ingvar Kamprad, one of the world's most successful entrepreneurs.Born in Sweden in 1926, Kamprad was a natural businessman.As a child, he enjoyed selling things and made small profits from selling matches, seeds, and pencils in his community.When Kamprad was 17, his father gave him some money as a reward for his good grades.Naturally he used it to start up a business--IKEA. IKEA's name comes from Kamprad's initials (I.K.) and the place where he grew up ('E'and 'A').Today IKEA is known for its modern, minimalist furniture, but it was not a furniture company in the beginning.Rather, IKEA sold all kinds of miscellaneous goods. Kamprad's wares included anything that he could sell for profits at discounted prices, including watches, pens and stockings. IKEA first began to sell furniture through a mail-order catalogue in 1947.The furniture was all designed and made by manufacturers near Kamprad's home.Initial sales were very encouraging, so Kamprad expanded the product line.Furniture was such a successful aspect of the business that IKEA became solely a furniture company in 1951. In 1953 IKEA opened its first showroom in Almhult, Sweden.IKEA is known today for its spacious stores with furniture in attractive settings, but in the early1950s, people ordered from catalogues.Thus response to the first showroom was overwhelming: people loved being able to see and try the furniture before buying it.This led to increased sales and the company continued to thrive.By 1955, IKEA was designing all its own furniture. In 1956 Kamprad saw a man disassembling a table to make it easier to transport.Kamprad was inspired.The man had given him a great idea: flat packaging.Flat packaging would mean lower shipping costs for IKEA and lower prices for customers.IKEA tried it and sales soared.The problem was that people had to assemble furniture themselves, but over time, even this grew into an advantage for IKEA.Nowadays, IKEA is often seen as having connotations of self-sufficiency.This image has done wonders for the company, leading to better sales and continued expansion. Today there are over 200 stores in 32 countries.Amazingly, Ingvar Kamprad has managed to keep IKEA a privately-held company.In 2004 he was named the world's richest man.He currently lives in Switzerland and is retired from the day-to-day operations of IKEA.IKEA itself, though, just keeps on growing. The passage is developed primarily in terms of _ .

It has been two years since China Daily last interviewed 31-year-old Zhang Chao.The micrograph enthusiast still wears the same hair style, even the same coat. But one thing is very different: He's become a celebrity in cyberspace almost overnight, after his pictures, which show what the smog in Beijing looks like under his microscope, spread like a virus on China's major micro-blogging site Sina Weibo, since he posted them last Friday.Now the media is always interviewing him. Zhang's apartment is on the eighth floor, which he says is perfect for capturing the thickest levels of smog. As a Beijing native, Zhang explains his original purpose is to _ and expose its mystery." People have higher and higher standards for the environment," he says," When I was a child, I was annoyed by the frequent sandstorms, so I feel Beijing's air seems much better now all in all because there are hardly any sandstorms in recent years.Now, we've noticed PM2.5, which has long been neglected." Although he graduated as a science major from Beijing Normal University, Zhang says it is difficult for him to give an exact definition of what smog is in Beijing. Under his scope, which magnifies the sample 1,000 times, the smog is found to contain minerals, fragments of animal fur and insects, seeds and burnt dust.But many are compounds, he says, which are more difficult to identify. Zhang realizes that he may have disappointed the public because he can't show the inner construction of PM2.5 , today's most notorious(.) element in smog. It is beyond the capacity of his microscope and camera to explore such tiny grains, " You cannot imagine how splendid the micro world is" ! says Zhang Chao. From the passage we can infer that _ .

As a young child, I was quiet and shy. I was also sick for a long time. My parents worked, and I spent a lot of time at my grandparent's home. While my grandmother cleaned the house and cooked, my grandfather played with me. I was six when my grandfather died. A few months before he died, he gave me a beautiful blue and white blanket . I loved the blanket very much because it made me think of my grandfather. But after a few years, the blanket didn't look very good. It had holes and was dirty. I didn't want to throw the blanket away, so my mother made the blanket into a book bag. I was proud of the book bag, and I used it to carry my books to school every day for a few years. Then the book bag was broken. I begged my mother to make something out of it. She made it into a pencil-box. After a few months, the pencil-box was broken, too. By then I could sew , and I made the pencil-box into a small wallet. I used it for three years, but one day I lost it. I felt sad. My friends and family said, "Forget about it, Paul.

mmlu | Question:
In promising to fuse media as diverse as television, telephone communication, video games, music and data transmission, the era of digital convergence goes better than yesterday's celebrated "information superhighway." Yet achieving this single technology is far from straightforward. There are currently three major television broadcast standards, and they are all incompatible with each other. But this is nothing compared to the many technologies supporting the Internet, each with a different bandwidth and physical media. The problems faced in designing platforms and communication systems that will be accepted across the world can appear insuperable. Even once global standards are assured, however, a further obstacle lies in wait. The Internet is plagued by long, erratic (,) response times because it is a pull-technology, driven by patterns of user demands. Push-technology, on the other hand, reverses the relationship: servers simply send information to passive users, as in television and radio. But if some form of combination between one-way television flow and interactive Internet is to be the basis of our future media, it is hard to see how it could be operated. Moreover, the problem of fusing Internet with television is also one of defining the services offered. Information, entertainment and relaxation appear at first to be quite different needs. Serious doubts remain over whether consumers will be interested in having to make the sort of mental effort associated with computing while also settling down in front of a sitcom . Besides the issue of consumer habits, infrastructurecosts are set to be immense, and will have to be met by national states or the private sector before being passed on to users. Platforms do not necessarily have to be expensive. The mobile phone is a good example of how something that is technologically sophisticated can almost be given away, with its cost recovered through service charges. Users are then coercedthrough clever marketing to upgrade to newer phones with more features to reinforce their dependence. Whatever the outcome, it is obvious that technology will play an increasing part in our everyday lives. Beyond technology, digital convergence embraces the services, industrial practices and social behavior that form modern society. We have in our hands the technology to construct the most sophisticated machines ever built, but if they are unusable, simply because of their operating instructions, then recent lessons have taught us they will not survive. Whatever we design must be simple, reliable and useful. Perhaps this is where artificial intelligence will come in. What is pull technology?
Choices:
A. It is the Internet system affected by long, uncertain response times.
B. It is the way of business operation driven by user demands.
C. It is the technology to send information to passive users.
D. It is a way to blend one-way television with interactive Internet. | B |

"Beauty is only skin deep." This expression means that beauty is only a temporary surface quality. Some beauty products can cause lasting damage that goes far below the surface of the skin. In America,many people use sunlight and non-natural light to darken their skin. Health experts advise against what is called"tanning"because of its links to akin cancer. In the African country of Senegal ,some women take health risks trying to do just the opposite. An average beauty supply shop in Dakar has many kinds of skin-lightening creams and soaps. The World Health Organization says that 25%of Senegalese women use skin-lightening production a usual basis. These products can contain chemicals,like mercury ,hydroquinone ,etc. These are dangerous ingredients that can cause cancer and possibly other physical damage to the akin. They can actually burn the eyes and skin. Shop worker Adama Diagne advises her visitors to avoid the stronger products that promise fast results. She users a cream that is made from carrots,not the strong chemical,hydroquinone. She says that it is a personal choice and that no one pressures her. Some women want to be black every day,but for her,she likes to be a shade of brown. Women in Senegal say they lighten their skin for the same reason that women all over the world make changes to their appearance. They say they want to look beautiful,to find a husband, to stand out in a crowd or simply to look great for a special event. This thinking troubles Senegalese film-maker Khardiata Pouye Sall. So,she made"This Color That Bothers Me",a film about the subject of skin lightening. She said,"I used the most shocking images so that women would see the dangers. It is hard to understand why a woman says that dark skin is not beautiful. It is in their heads. They want to please a man,to he loved or they want to please society,to succeed." Ms. Sall says that the government needs to better control the marketing and the sale of skin-lightening products. But she adds that education is the best way to persuade people against using them. We can infer that women in Senegal _ .

B. don't consider dark skin to be beautiful
C. find it hard to understand the true beauty

Follow these tips to adjust to your new life rapidly and make the most of your college experience. * To save time and money, use the college' s bus system. Taking the bus to school is quick, easy and free in most college towns. You won' t have to locate or afford a place to park either.

We knew Sylvia and Jack had problems with their flats, but we hadn't been told the details. Not until they came for a weekend in October, that is. At dinner on the Friday evening Kitty said, "You wrote that the flat wasn't quite what you expected. Of course it could be too small. You're sharing with another couple, aren't you?" "Were sharing. Mother." Sylvia replied. "It really wasn't necessary." Jack explained proudly, "I've had a big rise, and we can easily manage. It's much better to be independent." "Oh, much," I agreed "What was the trouble?" Kitty asked, impatient and unwilling to let her go. "Nothing much." Sylvia said, "The flat is fine. It was the other couple. Sally and Tom Ford. You've never seen such an untidy pair. We shared the sitting room and the kitchen and the bathroom and got fed up with the mess of it all." "And what made it worse," Jack put in. "was that they accused us of the same sort of thing. Tom and I nearly came to blows when he locked up some of their wedding presents we were all using, as they used ours, naturally." "You take a chance when you make a sharing arrangement." Kitty said. "I am in my own flat." Sylvia said, "Sally and Tom left a month ago." "We could have left instead," Jack said, "But why we should leave? After all, the flat was in out names, not theirs. We were glad to see the back of them." Two weeks later Kitty and I retuned their visit for lunch on Sunday. It was the first time we had been to their flat.

LONDON---The International Table Tennies Federation(ITTF) plans to work with Bill Gates, the chairman of Microsoft Corporation, to promote table tennis in the United States, ITTF President Adham Sharara said. The plan was put forward after Gates came to London to watch the game between US teen player Ariel Hsing and Chinese Li Xiaoxia on Sunday, Sharara told Xinhua in an interview. Sharara didn't disclose the details, but said that Gates offered to help after watching Hsing's match, in which the 16-year-old girl nearly pulled off one of the biggest upsets in Olympic table tennis history, pushing No. 2 seed Li to the limit before losing 4-2 in six tight sets. "Gates was surprised to see the young American girl played so well. He asked me what he can do to help promote table tennis in the United States. I think we'll work with him. If the United States becomes very strong in table tennis, it's also good for China," Sharara said. Sharara said the case is a "good example" which shows that ITTF's efforts in promoting the popularity. The ITTF has changed its rules for the London Games, allowing only two players from one nation to enter the singles events. Three players from each National Olympic Committee(NOC) were allowed to enter the singles in previous Games. "The reason we do this is to help more NOCs to join in our game. If we give more chances to the top countries, someone like Hsing will not come to the Olympic Games. They have no chance. But if we give them the chance, we can see what they can do," Sharara said. Sharara said the change increased the pressure on strong teams, like China, Japan, South Korea and Germany. "But they understand now because they saw other NOCs attending. Some countries before had no chance to play in table tennis, but now they are joining in table tennis." Other changes made to the Olympic Games include the color of floor (from red to blue) and new table design. "As far as presentation is concerned, we try to change all the time, especially in the Olympic Games. We hope to give audiences something new, exciting and cool." Table tennis has long been the strengths of Asia, especially China. Since the sport was introduced into the Olympics in 1988, China has taken 20 of 24 gold medals available. Four years ago in Beijing, it claimed six medals in the men's and women's singles. Talking about the development of table tennis, Sharara said, "China has the responsibility to promote the sport. Of course, China has done a lot." What gave Gates more confidence to promote table tennis in the United States?
Choices:
A. The Olympic spirits.
B. The popularity of table tennis.
C. Sharara's patient persuasion.
D. Ariel Hsing's wonderful performance. | D |

mmlu | Question:
Japanese doctors have used thin sheets of tissue from people's cheeks repair damaged corneas . A team from Osaka University transplanted thin layers of cheek cells onto the eyes of four patients with a rare and painful eye condition,reports BBC online. Patients whose vision had been cloudy could see well afterwards,and the"new corneas"remained clear more than a year after the operation. Doctors can also take cells from a healthy eye and grow them in a dish to produce a new cornea,or they can transplant corneas from donors . But these techniques may not work when both eyes are too badly damaged by accident or disease. The team hope their work may help solve the problem and lead to other types of grow-your-own tissue transplants. The cornea is the clear layer of cells on the surface of the eye. It can be damaged by trauma or by a range of diseases. The team worked with four patients who had a painful condition that causes cloudy corneas and dry eyes. Often the eye can regenerate cornea cells but none of the four patients had this ability. The researchers took a 3 mm-wide square of tissue from inside the mouth(cheeks)and grew it into a thin layer in the lab. They used a special low temperature technique to separate a very thin sheet off each batch. They then laid that onto the patient's eye. The cell layers stuck onto the eye and developed into tissue that looked and acted like a healthy cornea. However,long-term follow-up and experience with a large series of patients is needed to assess the benefits and risks this method. Yet,"it does offer the potential of treating severe eye diseases that are resistant to standard approaches,"said the head of the research,Kohji Nishida. If both eyes are too badly damaged,we can treat them _ .
Choices:
A. only by using mouth tissue
B. by taking cells from a healthy eye and growing them in a dish

Some of the greatest problems we face today are the destruction of our environment. Brown clouds, polluted water,endangered wild animals.... these problems seem so huge. So my family does what we can. We take cloth bags to stores instead of using plastic bags. We walk where we don't have to drive... But does it do any good? When I am the only one in line at the market with cloth bags, am I doing any good? Does my walking to stores make any real difference to the world? I recently learned something about flamingos which like to get together in groups of a thousand or more. Every year, when the time comes for migration ,a few of them first take off from the lake. But none of the others seem to notice. So the small group returns. However, the next day they try again. This time a few more fly along with them, but most of them still pay no attention, so they return again. They try for several times. Every time a few more birds join in but, since thousands of the others still take no notice, the great migration plan is once more stopped. Then one day something changes. The same small group of birds once again starts flying and a small number more join in just as before. then more. Finally, they all take flight and the migration really begins. What a _ sight it must be -- thousands of flamingos taking off into the sky at once ! A few can make a difference. Even if you're the one to take the first step, and continue trying, others will someday take notice and together we will solve even our greatest problems. Where would you most probably read this passage?
