Passage One

It's official: Money can't buy happiness.

Sure, if a person is handed $10, the pleasure centres of his brain light up as if he were given food, sex, or drugs. But that initial rush does not translate into long-term pleasure for most people. Surveys have found virtually the same level of happiness between the very rich individuals on the Forbs 400 and the Maasai herdsmen of East Africa. Lottery winners return to their previous level of happiness after five years. Increases in income just don't seem to make people happier-and most negative life experiences likewise have only a small impact on long-term satisfaction.

"The relationship between money and happiness is pretty darned(非常)small," says Peter Ubel, a professor of medicine at the University of Michigan.

That's not to say that increased income doesn't matter at all. There is a very small correlation between wealth and happiness-accounting for about one percent of the happiness reported by people answering the surveys. And for some groups, that relationship may be considerably bigger. People who are poor seem to get much happier when their monetary prospects improve; so do the very sick. In these cases, Ubel speculates, people may be protected from negative circumstances by the extra cash. Another possibility is that the money brings an increase in status, which may have a greater impact on happiness.

Why doesn't wealth bring a constant sense of joy? "Part of the reason is that people aren't very good at figuring out what to do with the money," says George Loewenstein, an economist at Carnegie Melton University. People generally overestimate the amount of long-term pleasure they'll get from a given object.

Sometimes, Loewenstein notes, the way people spend their money can actually make them less happy. For example, people derive a great deal of pleasure from interacting with others. If the first thing lottery winners do is to quit their job and to move to a palatial(富丽堂皇的)but isolated estate where they don't see any neighbours, they could find themselves isolated and depressed.

1. The first sentence of the passage means_.

A. it is announced by government that money can't buy happiness

B. it is justified that money can't buy happiness

C. it is authoritative that money can't buy happiness

D. it is fair that money can't buy happiness

2. We can infer that if one is very sad at some time in his life,_.

A. he will be sad all his life

B. he will never be happy

C. he may be happy at other time

D. he may be influenced by the sadness all the time

3, According to Ubel,_.

A. money has much to do with happiness

B. increases in money may make people happy

C. money doesn't matter at all

D. money has no effect on happiness

4. Wealth doesn't assure one of long-term pleasure because_·

A. they don't know what to do with the money

B. they are not good at using the money

C. they generally expect more pleasure than money can bring

D. they are not content with the wealth

5. Lottery winners may not be happy—·

A. if they quit their job

B. if they move to a splendid house

C. if they spend a lot of money

D. if they are away from others

Passage Two

Transplant surgeons work miracles. They take organs from one body and integrate them into another, granting the lucky recipient a longer, better life. Sadly, every year thousands of other people are less fortunate, dying while they wait for suitable organs to be found. The terrible constraint on organ transplantation is that every life extended depends on the death of someone young enough and healthy enough to have organs worth transplanting. Such donors are few. The waiting lists are long, and getting longer.

Freedom from this constraint is the dream of every transplant surgeon. So far attempts to make artificial organs have been disappointing: Nature is hard to mimic. Hence the renewed interest in trying to use organs from animals.

Doctors in India have just announced that they have successfully transplanted a heart from a pig into a person. Pressure to increase the number of such "xenotransplants"(异种移植)seem to be growing. In Europe and America, herds of pigs are being specially bred and genetically engineered for organ donation. During 1996 at least two big reports on the subject-one in Europe and one in America- were published. They agreed that xenotransplantation was permissible on ethical grounds, and cautiously recommended they be allowed.

The ethics of xenotransplantation are relatively unworrying. People already kill pigs both for food and for sport; killing them to save a human life seems, if anything, easier to justify. However, the science of xenotransplantation is much. less straightforward.

Import an organ from one animal to another and you may bring with it any number of infectious diseases. That much is well known. However, coping with this danger is not merely a matter of screening for obvious ills such as parasites. Many diseases that could harm humans may be both undetectable and harmless in their natural hosts. Diseases that have been dormant for years may suddenly become active if they find themselves in a new environment, such as a human recipient's body. After that, they may start to infect other people.

1. Despite transplant surgeons' work, every year many people die because_.

A. they are unlucky patients

B. organ transplantation is unreliable

C. there are not enough proper organs for transplantation

D. few people are willing to donate their organs after death

2. Which of the following is NOT a limitation of organ transplantation?

A. The organ donor must be young enough.

B. The organ donor must be healthy enough.

C. The organ donated must deserve transplanting.

D. The organ donated must be removed from one body.

3. Attempts to make artificial organs fail because_，

A. it is difficult to make artificial organs as natural as body organs

B. it is difficult to imitate the human world

C. the production process is complicated

D. the production is limited by nature

4. The danger of transplanting animal organs into humans is that_，

A. it is considered ethically wrong

B. it may bring diseases into human bodies

C. it brings parasites into human bodies

D. it does more harm than good to humans

5. The word "dormant" (Line 4, Para. 5) means_

A. hidden

B. inactive

C. potential

D. devil

大学英语四级模拟试题四(附含答案解析)

大学英语四级模拟题四 Part One Reading Comprehension (2’×10 = 20’) Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A), B), C) and D). You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the centre. Passage One Air pollution can spread from city to city. It even spreads from one country to another. Some northern European countries have had “black snow”from pollutants that have traveled through the air from other countries and have fallen with the snow. So air pollution is really a global problem. Air pollution can kill babies, older people, and those who have respiratory（呼吸的）diseases. As found in cities, air pollution increases the risks of certain lung diseases. Air pollution can cause both airplane and car accidents because it cuts down visibility （能见度）. There are other possible health dangers from air pollution that we don’t know much about. For example, scientists are trying to find out whether chemicals that reach us from the air may cause changes in our cells. These changes might cause babies to be born with serious birth defects. Scientists are trying to learn how all the many chemicals are apt（易于的）to take into our bodies from air, water, food, and even medicines act together to affect our health and the way our bodies work. That is another reason why it is so important to begin to control pollution now instead of waiting until we learn all the answers. Air pollution costs us a lot of money. It corrodes（腐蚀）our buildings. It damages farm crops and forests. It has a destructive effect on our works of art. The cost of all this damage to our government is great. It would be much more worthwhile, both for us and for the government, to spend our tax dollars on air pollution control. 1. Air pollution may lead to airplane accidents because . A. it may cause pilots to be ill B. engines may fail from the air-borne dirt C. visibility is reduced D. it brings a lot of black snow 2. Scientists are trying to find a link between pollution and . A. intelligence levels B. birth problems C. man’s behavior D. the nervous system 3. Scientists have not yet determined . A. all of the effects of pollution on the human body B. how pollution can be controlled successfully C. when the atmosphere first became polluted D. how some snow becomes black 4. The author suggests that before air pollution becomes more serious, . A. factories will be forced to stop operating B. buildings should be protected C. the earth will begin to grow colder D. more money should be spent to solve the problem 5. We can conclude that . A. civilization may be ruined if pollution is not controlled B. pollution is more serious in Europe than it is in America C. most people do not know that pollution is a serious problem D. we should learn all the answers before we begin to control pollution Passage Two Stiletto heels could be banned from the workplace because of health and safety reasons, according to British Trade Union bosses. The Trade Union Congress, predominantly male, has proposed a motion arguing that high heels are disrespectful to women while they also contribute to long term injuries. They propose instead that women wear “sensible shoes”with an inch heel limit in an attempt to avoid future foot and back pain as well as injuries. The motion is due to be debated at next month’s conference. The motion states: “Congress believes high heels may look glamorous on the Hollywood catwalks but are completely in appropriate for the day-to-day working environment. Feet bear the burden of daily life, and for many workers prolonged standing, badly fitted footwear, and in particular high heels can be a hazard. Around two million days a year are lost through sickness as a result of lower limb disorders. Wearing high heels can cause long-term foot problems and also serious foot, knee and back pain and damaged joints. Many employers in the retail sector force women workers to wear high heels as part of their dress code. More must be done to raise awareness of this problem so that women workers and their feet are protected.” Nadline Dorries, the Tory Member of Parliament, however criticized the motion and said the extra height heels give women can help them when in the workplace. “I’m 5ft 3in and need every inch of my Christian Louboutin heels to look my male colleagues in the eye,”she said. “If high heels were banned in Westminster, no one would be able to find me. The Trade Union leaders need to get real, stop using obvious sexist tactics by discussing women’s

Calculate for a moment what could be done with even a part of those hours. Five thousand hours, I am told, are what a typical college undergraduate spends working on a bachelor's degree. In 10,000 hours you could have learned enough to become an astronomer or engineer. You could have learned several languages fluently. If it appealed to you, you could be reading Homer in the original Greek or Dostoyevsky in Russian. If it didn't, you could have walked around the world and written a book about it. The trouble with television is that it discourages concentration. Almost anything interesting and rewarding in life requires some constructive, consistently applied effort. The dullest, the least gifted of us can achieve things that seem miraculous to those who never concentrate on anything. But Television encourages us to apply no effort. It sells us instant gratification(满意). It diverts us only to divert, to make the time pass without pain. Television's variety becomes a narcotic(麻醉的), nor a stimulus. Its serial, kaleidoscopic (万花筒般的)exposures force us to follow its lead. The viewer is on a perpetual guided tour: 30 minutes at the museum, 30 at the cathedral, 30 for a drink, then back on the bus to the next attraction—except on television., typically, the spans allotted arc on the order of minutes or seconds, and the chosen delights are more often car crashes and people killing one another. In short, a lot of television usurps(篡夺;侵占) one of the most precious of all human gifts, the ability to focus your attention yourself, rather than just passively surrender it. Capturing your attention—and holding it—is the prime motive of most television programming and enhances its role as a profitable advertising vehicle. Programmers live in constant fear of losing anyone's attention—anyone's. The surest way to avoid doing so is to keep everything brief, not to strain the attention of anyone but instead to provide constant stimulation through variety, novelty, action and movement. Quite

Material culture refers to what can be seen, held, felt, used -what a culture produces. Examining a culture’s tools andtechnology can tell us about the group’s history and way of life. Similarly, research into the material culture of mus ic can help us to understand the music-culture. The most vivid body of material culture in it, of course, are musical instruments. We cannot hear for ourselves the actual sound of any musical performance before the 1870s when the phonograph (留声机) was invented, so we rely on instruments for important information about music-cultures in the remote past and their development. Here we have two kinds of evidence: instruments well preserved and instruments pictured in art. Through the study of instruments, as well as paintings, written documents, and so on, we can explore the movement of music from the Near East to China over a thousand years ago, or we can outline the spread of Near Eastern influence to Europe that resulted in the development of most of the instruments in the symphony orchestra（交响乐）. Sheet music（乐谱）or printed music, too, is material culture. Scholars once defined folk music-cultures as those in which people learn and sing music by earrather than from print, but research shows mutual influence among oral and written sources during the past few centuries in Europe, Britain, and America. Printed versions limit variety because they tend to standardize any song, yet they stimulate people to create new and different songs. Besides, the ability to read music notation（乐谱）has a far-reaching effect on musicians and, when it becomes widespread, on the music-culture as a whole. One more important part of music’s material culture should be singled out: the influence of the electronic media-radio, record player, tape recorder, television, and videocassette, with the future promising talking and singing computers a nd other developments. This is all part of the “information revolution”, a twentieth-century phenomenon as important as the industrial revolution was in the nineteenth. These electronic media are not just limited to modern nations; they have affected music-cultures all over the globe. 31. Research into the material culture of a nation is of great importance because ____. A) it helps produce new cultural tools and technology B) it can reflect the development of the nation C) it helps understand the nation’s past and present D) it can demonstrate the nation’s civilization 32. It can be learned from this passage that ____. A) the existence of the symphony was attributed to the spread of Near Eastern and Chinese music

大学英语四级考试模拟试卷及参考答案(第一套） Part II Reading Comprehension (35 minutes) Directions: There are 4 reading passages in this part. Each passage is foll owed by some questions or unfinished statements. For each of them there are fou r choices marked A), B), C) and D). You should decide on the best choice and ma rk the corresponding letter on the Answer Sheet with a single line through the center. Passage One Questions 21 to 25 are based on the following passage. There is a difference between science and technology. Science is a method o f answering theoretical questions; technology is a method of solving practical problems. Science has to do with discovering the facts and relationships betwee n observable phenomena in nature and with establishing theories that serve to o rganize these facts and relationships; technology has to do with tools, techniq ues, and procedures for implementing the finding of science. Another distinction between science and technology has to do with the progr ess in each. Progress in science excludes the human factor. Scientists, who seek to comp rehend the universe and know the truth within the highest degree of accuracy an d certainty, cannot pay attention to their own or other people's likes or disli kes or to popular ideas about the fitness of things. What scientists discover m ay shock or anger people-as did Darwin's theory of evolution. But even an unple asant truth is more than likely to be useful; besides, we have the choice of re fusing to believe it! But hardly so with technology; we do not have the choice
