第31篇：(Unit 8, Passage 3)
For four lonely years, Evelyn Jones of Rockford, Illinois, lived friendless and forgotten in one room of a cheap hotel. “I wasn’t sick, but I was acting sick,” the 78-year-old widow says. “Every day was the same—I would just lie on my bed and maybe cook up some soup.” Then, six months ago, she was invited to “The Brighter Side”—Rockford’s day care center for the elderly. Every weekday morning since then, she has left her home to meet nine other old people in a church for a rich program of charity work, trips, games, and—most important of all—friendly companionship.
Just a few years ago, there were few choices for the elderly between a normal life in their own homes and being totally confined in nursing homes. Many of them were sent to rest homes long before they needed full-time care. Others like Mrs. Jones, were left to take care of themselves. But in 1971, the White House Conference on Aging called for the development of alternatives to care in nursing homes for old people, and since then, government-supported day-care programs like The Brighter Side have been developed in most big American cities.
“This represents a real alternative to the feared institution and makes old people believe they have not left the world of living,” says Alice Brophy, 64, director of New York City’s Office for the Aging. “They do well at the centers, and I hate it when people describe us as elderly playpens.” New York’s 138 centers encourage continuing contact for the aged with the community’s life. The centers serve more than 15,000 members, and volunteer workers are always looking for new ones. If someone doesn’t show up at the center for several days in a row, a worker at the center calls to make sure all is well. And although participation in the center is free, those who want to can pay for their lunches.
No normal studies have been made of these centers for the elderly, but government officials are enthusiastic. In the future, the Public Health Service will do a study to decide if the programs can receive federal Medicare money. And the old people themselves are very happy with the programs. “There is no way,” says Evelyn Jones, smiling at her new companions at the Brighter Side, “that I will ever go back to spending my day with all those loses at the hotel.”
1.What is the main idea of the article?
A.Day care centers may be able to receive federal Medicare money.
B.Day care centers can make life better for elderly people.

第32篇：(Unit 8, Passage 4)
Drunken driving--sometimes called America’s socially accepted form of murder--has become a national epidemic. Every hour of every day about three Americans on average are killed by drunken drivers, adding up to an incredible 250,000 over the past decade.
A drunken driver is usually defined as one with a 0.10 blood alcohol content or roughly three beers, glasses of wine or shots of whisky drunk within two hours. Heavy drinking used to be an acceptable part of the American macho image and judges were lenient in most courts, but the drunken slaughter has recently caused so many well-publicized tragedies, especially involving young children, that public opinion is no longer so tolerant.
Twenty states have raised the legal drinking age to 21, reversing a trend in the 1960s to reduce it to 18. After New Jersey lowered it to 18, the number of people killed by 18-20-year-old drivers more than doubled, so the stat
[1] [2] [3] [4] [5] [6] [7] [8] [9] 下一页
e recently upped it back to 21.
Reformers, however, fear raising the drinking age will have little effect unless accompanied by educational programs to help young people to develop “responsible attitudes” about drinking and teach them to resist peer pressure to drink.
Though new laws have led to increased arrests and tests and, in many areas already, to a marked decline in fatalities. Some states are also penalizing bars for serving customers too many drinks. A tavern in Massachusetts was fined for serving six or more double brandies to a customer who “obviously intoxicated” and later drove off the road, killing a nine-year-old boy.
As the fatalities continue to occur daily in every state, some Americans are even beginning to speak well of the 13 years of national prohibition of alcohol that began in 1919, what President Hoover called the “ noble experiment.” They forgot that legal prohibition didn’t stop drinking, but encouraged political corruption and organized crime. As with the booming drug trade generally, there is no easy solution.
1.Drunken driving had become a major problem in America because ___.
A.most Americans are heavy drinkers.
B.Americans are now less shocked by road accidents.
C.accidents attract so much publicity.
D.drinking is a socially accepted habit in America.
2.Why has public opinion regarding drunken driving changed?
A.Because detailed statistics are now available.
B.Because the news media have highlighted the problem.
C.Because judges are giving more severe sentences.
D.Because drivers are more conscious of their image.
3.Statistics issued in New Jersey suggested that ___.
A.many drivers were not of legal age.
B.young drivers were often bad drivers.
C.the level of drinking increased in the 1960s.
D.the legal drinking age should be raised.
4.Laws recently introduced in some states have ___.
A.reduced the number of convictions.
B.resulted in fewer serious accidents.
C.prevented bars from serving drunken customers.
D.specified the amount drivers can drink.
5.Why is the problem of drinking and driving difficult to solve?
A.Because alcohol is easily obtained.
B.Because drinking is linked to organized crime.
C.Because legal prohibition has already failed.
D.Because legislation alone is not sufficient.

第三十三篇：(Unit 9,Passage 1)
Fresh water life itself, has never come easy in the Middle East. Ever since the Old Testament(旧约圣经) God punished man with 40 days and 40 nights of rain, water supplies here have been dwindling. The rainfall only comes in winter, Inshallah ----- Good willing –and drains quickly through the semiarid land, leaving the soil to bake and to thirst for next November.
The region’s accelerating population, expanding agriculture, industrialization, and higher living standards demand more fresh water. Drought and pollution limit its availability. War and mismanagement squander it. Says Joyce Starr of the Global Water Summit Initiative, based in Washington, D.C.” Nations like Israel and Jordan are swiftly sliding into that zone where they are suing all the water resources available to them. They have only 15 to 20 years left before their agriculture, and ultimately their food security, is threatened.”
I came here to examine this crisis in the making, to investigate fears that “water wars “are imminent, that water has replaced oil as the region’s most contentious commodity. For more than two months I traveled through three river valleys and seven nations -----from southern Turkey down the Euphrates River Syria, Iraq, and on to Kuwait; to Israel and Jordan, neighbors across the valley of the Jordan; to the timeless Egyptian Nile.
Even amid the scarcity there are haves and have – notes. Compared with the United States, which in 1990 had a freshwater potential of 10000 cubic meters(2.6 million galloons) a year for each citizen, Iraq had 5 500, Turkey had 4 000, and Syria had more than 2 800. Egypt’s potential was only 1 100. Israel had 460, Jordan a meager 260. But these are not firm figures, because upstream use of river water can dramatically alter the potential downstream.
Scarcity is only one element of the crisis. Inefficiency is another, as is the reluctance of some water – poor nations to change priorities from agriculture to less water – intensive enterprises. Some experts suggest that if nations would share both water technology and resources, they could satisfy the region’s population, currently 159 million. But

in this patchwork of ethnic and religious rivalries, water seldom stands alone as an issue. It is entangled in the politics that keep people from trusting and seeking help from one another. Here, where water, like truth, is precious, each nation tends to find its own water and supply its own truth.
As Israeli hydrology professor Uri Shamir told me :” If there is political will for peace, water will not be a hindrance. If you want reasons to fight, water will not e a hindrance. If you want reasons to fight, water will give you ample opportunities.”
1.Why “for next November” (para.1)? Because________.
A.according to the Ole Testament fresh water is available only in November
B.rainfall comes only in winter starting form November
C.running water systems will not be ready until next November
D.it is a custom in that region that irrigation to crops is done only in November
2.What is the cause for the imminent water war?
A.Lack of water resources B.Lack of rainfall
C.Inefficient use of water D.All the above
3.One way for the region to use water efficiently is to _______
A.develop other enterprises that cost less water
B.draw a plan of irrigation for the various nations
C.import water from water – rich nations
D.stop wars of any sort for good and all
4.Uri Shamir’s viewpoint is that ________.
A.nations in that region are just fighting for water
B.people there are thirsty for peace instead of water
C.water is no problem as long as there is peace
D.those nations have every reason to fight for water
5.The author’s tone in the article can be described as ______-.
A.depressing B.urgent C.joking D.mocking

第34篇：(Unit 9,Passage 2)
The British psychoanalyst John Bowlby maintains that separation from the parents during the sensitive “attachment” period from birth to three may scar a child’s personality and predispose to emotional problems in later life. Some people have drawn the conclusion from Bowlby’s work that children should not be subjected to day care before the age of three because of the parental separation it entails, and many people do believe this. But there are also arguments against such a strong conclusion.
Firstly, anthropologists point out that the insulated love affair between children and parents found in modern societies does not usually exist in traditional societies. For example, we saw earlier that among the Ngoni the father and mother of a child did not rear their infant alone--far from it. Secondly, common sense tells us that day care would not so widespread today if parents, caretakers found children had problems with it. Statistical studies of this kind have not yet been carried out, and even if they were, the results would be certain to be complicated and controversial. Thirdly, in the last decade, there have been a number of careful American studies of children in day care, and they have uniformly reported that day care had a neutral or slightly positive effect on children’s development. But tests that have had to be used to measure this development are not widely enough accepted to settle the issue.
But Bowlby’s analysis raises the possibility that early day care has delayed effects. The possibility that such care might lead to, say, more mental illness or crime 15 or 20 years later can only be explored by the use of statistics. Whatever the long-term effects, parents sometimes find the immediate effects difficult to deal with. Children under three are likely to protest at leaving their parents and show unhappiness. At the age of three or three and a half almost all children find the transition to nursery easy, and this is undoubtedly why more and more parents make use of child care at this time. The matter, then, is far from clear-cut, though experience and available evidence indicate that early care is reasonable for infants.
1.This passage primarily argues that ___.
A.infants under the age of three should not be sent to nursery schools.
B.whether children under the age of three should be sent to nursery schools.
C.there is not negative long-term effect on infants who are sent to school before they are three.
D.there is some negative effect on children when they are sent to school after the age of three.
2.The phrase “predispose to” (Pa

ra. 1, line 3) most probably means ___.
A.lead to
B.dispose to
C.get into
D.tend to suffer
3.According to Bowlby’s analysis, it is quite possible that ___.
A.children’s personalities will be changed to some extent through separation from their parents.
B.early day care can delay the occurrence of mental illness in children.
C.children will be exposed to many negative effects from early day care later on.
D.some long-term effects can hardly be reduced from children’s development.
4.It is implied but not stated in the second paragraph that ___.
A.traditional societies separate the child from the parent at an early age.
B.Children in modern societies cause more troubles than those in traditional societies.
C.A child did not live together with his parents among the Ngoni.
D.Children in some societies did not have emotional problems when separated from the parents.
5.The writer concludes that ___.
A.it is difficult to make clear what is the right age for nursery school.
B.It is not settled now whether early care is reasonable for children.
C.It is not beneficial for children to be sent to nursery school.
D.It is reasonable to subject a child above three to nursery school.

第三十五篇(Unit 9, Passage 3)
The life story of the human species goes back a million years, and there is no doubt that man came only recently to the western hemisphere. None of the thousands of sites of aboriginal (土著的) habitation uncovered in North and South America has antiquity comparable to that of old World sites. Man’s occupation of the New World may date several tens of thousands of years, but no one rationally argues that he has been here even 100,000 years.
Speculation as to how man found his way to America was lively at the outset, and the proposed routes boxed the compass. With one or two notable exceptions, however, students of American anthropology soon settled for the plausible idea that the first immigrants came b way of a land bridge that had connected the northeast comer of Asia to the northwest corner of North America across the Bering Strait. Mariners were able to supply the reassuring information that the strait is not only narrow – it is 56 miles wide – but also shallow, a lowering of the sea level there by 100 feet or so would transform the strait into an isthmus (地峡). With little eels in the way of evidence to sustain the Bering Strait land bridge, anthropologists (人类学家) embraced the idea that man walked dryshod (不湿鞋的) from Asia to America.
Toward the end of the last century, however, it became apparent that the Western Hemisphere was the New World not only for man but also for a host of animals and plants. Zoologists and botanists showed that numerous subjects of their respective kingdoms must have originated in Asia and spread to America. These findings were neither astonishing nor wholly unexpected. Such spread of populations is not to be envisioned as an exodus or mass migration, even in the case of animals. It is, rather, a spilling into new territory that accompanies increase in numbers, with movement in the direction of least population pressure and most favorable ecological conditions. But the immense traffic in plant and animal’s forms placed a heavy burden on the Bering Strait land bridge as the anthropologists ahead envisioned it. Whereas purposeful men could make their way across a narrow bridge, the slow diffusion of plant and animals would require an avenue as a continent and available for ages at a stretch.
1.The movement of plants and animals form Asia to America indicates ______.
A.that they could not have traveled across the Bering Strait
B.that Asia and the Western hemisphere were connected by a large land mass
C.that the Bering Sea was an isthmus at one time
D.that migration was in the one direction only
2.The author is refuting the notion that _____.
A.life arose in America independently of life in Europe
B.the first settlers in America came during the sixteenth century
C.a large continent once existed which has disappeared
D.man was a host to animals and plants
3.By using the words “boxed the compass “(in Line 7) the author implies that _____.
A.the migration of mankind was from West to East
B.the migration of mankind was from East to West
C.mankind traveled in all directions
D.mankind walked from Asia to America
4.One reason for the migration not mentioned by the author is _____.
A.overcrowding
B.favorable environ

5.We may assume that in the paragraph that follows this passage the author argues about______.
A.the contributions of anthropologist

第36篇(Unit 9, Passage 4)
There was on shop in the town of Mufulira, which was notorious for its color bar. It was a drugstore. While Europeans were served at the counter, a long line of Africans queued at the window and often not only were kept waiting but, when their turn came to be served, were rudely treated by the shop assistants. One day I was determined to make a public protest against this kind of thing, and many of the schoolboys in my class followed me to the store and waited outside to see what would happen when I went in.
I simply went into the shop and asked the manager politely for some medicine. As soon as he saw me standing in the place where only European customers were allowed to stand he shouted at me in a bastard language that is only used by an employed when speaking to his servants. I stood at the counter and politely requested in English that I should be served. The manager became exasperated and said to me in English, “If you stand there till Christmas I will never serve you.”
I went to the District commissioner’s office. Fortunately the District Commissioner was out, for he was one of the old school; however, I saw a young District Officer who was a friend of mine. He was very concerned to hear my story and told me that if ever I wanted anything more from the drugstore all I had to do was come to him personally and he would buy my medicine for me. I protested that that was not good enough. I asked him to accompany me back to the store and to make a protest to the manager. This he did, and I well remember him saying to the manager, “Here is Mr. Kaunda who is a responsible member of the Urban Advisory Council, and you treat him like a common servant.” The manager of the drugstore apologized and said, “If only he had introduced himself and explained who he was, then, of course I should have given him proper service.”
I had to explain once again that he had missed my point. Why should I have to introduce myself every time I went into a store…any more than I should have to buy my medicine by going to a European friend? I want to prove that any man of any color, whatever his position, should have the right to go into any shop and buy what he wanted.
1.“Color bar” in the first paragraph comes closest in meaning to ___.
A.a bar which is painted in different colors.
B.the fact that white and black customers are served separately.
C.a bar of chocolate having different colors.
D.a counter where people of different colors are served with beer.
2.The writer was, at the time of the story, ___.
A.a black school teacher
B.an African servant
C.a black, but a friend of Europeans
D.a rich black
3.The manager of the drugstore shouted at the writer in a bastard language because ___.
A.he hadn’t learned to speak polite English.
B.he thought the writer wouldn’t understand English.
C.that was the usual language used by Europeans when speaking to Africans.
D.that was the only language he could speak when he was angry.
4.In the third paragraph, “he was one of the old school” means ___.
A.he believed in the age-old practice of racial discrimination.
B.he was a very old man.
C.he graduated from an old, conservative school.
D.he was in charge of an old school.
5.Why didn’t the writer wait at the window of the drugstore like other black African?
A.Because he thought he was educated and should be treated differently.
B.Because he thought, being an important person, he should not be kept waiting.
C.Because he thought his white friends would help him out.
D.Because he wanted to protest against racial discrimination.

第三十七篇：(Unit 10,Passage 1)
Jogging has become the most popular individual sport in America. Many theories, even some mystical ones, have been advanced to explain the popularity of jogging. The plain truth is that jogging is a cheap, quick and efficient way to maintain (or achieve )physical fitness.
The most useful sort of exercise is exercise that develops the heart, lungs, and circulatory systems. If these system
上一页 [1] [2] [3] [4] [5] [6] [7] [8] [9] 下一页
s are fit, the body is ready for almost any sport and for almost any sudden demand made by work or emergencies. One can train more specifically, as by developing strength for weight lifting or the ability to run straight ahead for short distances with great power s in football, but running trains your heart and lungs to deliver oxygen more efficiently to all parts of your body. It is worth noting that this sort of exercise is the only kind that can reduce heart disease, the number one cause of death in America.
Only one sort of equipment is needed – a good pair of shoes. Physicians advise beginning joggers not to run in a tennis or gym shoe. Many design advances have been made in only the last several years that make an excellent running shoe in dispensable if a runner wishes to develop as quickly as possible, with as little chance of injury as possible. A good running shoe will have a soft pad for absorbing shock, as well as a slightly built-up heel and a full heelcup that will give the knee and ankle more stability. A wise investment in good shoes will prevent bilisters and the foot, ankle and knee injures and will also enable the wearer to run on paved or soft surfaces.
No other special equipment is needed; you can jog in any clothing you desire, even your street clothes. Many joggers wear expensive, flashy warm –up suits, but just as many wear a simple pair of gym shoes and T-shirt; in fact, many people just jog in last year’s clothes. In cold weather, several layers of clothing are better than one heavy sweater or coat. If joggers are wearing several layers of clothing, they can add or subtract layers as conditions change.
It takes surprisingly little time to develop the ability to run. The American Jogging Association has a twelve – week program designed to move form a fifteen-minute walk (which almost anyone can manage who is in reasonable health) to a thirty-minute run. A measure of common sense, a physical examination, and a planned schedule are all it takes.
1.They main purpose of this passage is to _____.
A.discuss jogging as a physical fitness program
B.describe the type of clothing needed for jogging
C.provide scientific evidence of the benefits of jogging
D.distinguish between jogging as a “common sense “fitness program and a cult (崇拜) movement
2.The most useful kind of exercise is exercise that ______.
A.trains the body for weigh lifting
B.enables a person to run straight ahead for short distances with great power
C.is both beneficial and inexpensive
D.develops the heart, lungs, and circulatory systems
3.We can conclude from this passage that ______.
A.because of jogging, heart disease is no longer an American problem
B.jogging can be harmful if the runner is not properly prepared
C.warm-up suits are preferable to gym shoes and T-shirts
D.jogging is bad for the ankles and knees
4.The author’s tone ______.
A.skeptical B.aggressive C.approving D.purely objective
5.As used in this passage, the word “mystical “ means ________.
A.awesome B.horrifying C.a spirtual discipline D.vicious

第38篇：(Unit 10,Passage 2)
There are spectacular differences between financial markets on the Continent of Europe on the one hand, and in Britain on the other hand. In Britain, the market is really the City of London. It is a free market, and it controls most of the flow of savings to investment. On the Continent, either a few banks or government officials direct the flow of funds to suit their economic plans. In Germany the flow is directed by all-powerful banks. In Britain there is more free interplay of market forces and far fewer regulations, rules and “red tape”. A French banker summed it up this way: “On the Continent you can’t do anything unless you’re been told you can; in England on the other hand you can do everything as long as you haven’t been told not to.”
There are many basic reasons for these differences. One is that Continental savers tend to prefer gold, cash or short-term assets. They invest only 10% of their savings in institutions like pension funds or insurance companies. But in Britain 50% of savings goes to them, and they, in turn, invest directly in equity market. A far lower proportion of savings is put in the banks in the form of liquid asse
上一页 [1] [2] [3] [4] [5] [6] [7] [8] [9] 下一页
ts than on the Continent. Continental governments intervene directly or through the banks to collect savings together and transform them into medium or long-term loans for investment. The equity market is largely bypassed. On the Continent economic planning tends to be far more centralized than in Britain. In Britain it is possible to influence decisions affecting the country’s economy from within the City. It attracts a skilled and highly qualified work force. In France, on the other hand, an intelligent young man who wants a career in finance would probably find the civil service more attractive.
In Britain the market, or more accurately, money tends to be regarded as an end in itself. On the Continent it is regarded as a means to an end: investment in the economy. To British eyes continental systems with possible exception of the Dutch seem slow and inefficient. But there is one outstanding fact the City should not overlook. Britain’s growth rates and levels of investment over the last ten years have been much lower than on the Continent. There are many reasons for this, but the City must take part of the blame. If it is accepted that the basic function of a financial market is to supply industry and commerce with finance in order to achieve desired rates of growth, it can be said that by concentrating on the market for its own sake the City has tended to forget that basic function.
1.What is the best title of the passage?
A.Savings and the Growth Rate.
B.Banking and Finance: Two Different Realities.
C.Monetary Policy in Britain.
D.The European Continent and Britain.
2.What seems to be the most fundamental reason for this difference?
A.The British tend to regard money as an end, whereas Continental European consider it a means to an end.
B.The British invest only 10% of their savings in pension funds.
C.On the Continent you can’t do anything unless you have been told you can.
D.Intelligent young men who want a career tend to go to civil service on the Continent.
3.According to the passage, the Dutch way of finance and banking ___.
A.is similar to that of the French.
B.makes no difference whatever system it is compared to.
C.is perhaps resembling that of the British.
D.has a low efficiency.
4.The word “outstanding” in Line 4, Para 3___
A.beating
B.surplus
C.noticeable
D.seemingly
5.In what way does the continental system seem better?
A.The Continent maintains a higher growth rate and levels of investment.
B.It has less proportion of savings in the form of liquid assets.
C.It attracts intelligent young men.
D.In functions properly despite the fact that the British discount it.

第39篇：(Unit 10, Passage 3)
The gift of being able to describe a face accurately is a rare one, as every experienced police officer knows to his cost. As the Lancet put it recently:” When we try to describe faces precisely words fail us, and we resort to identikit (拼脸型图) procedures.”
Yet, according to one authority on the subject, we can each probably recognise more than 1,000 faces, the majority of which differ in fine details. This, when one comes to think of it, is a tremendous feat, though, curiously enough, relatively little attention has been devoted to the fundamental problems of how and why we acquire this gift for recognizing and remembering faces. Is it an inborn property of our brains, or an acquired one? As so often happens, the experts tend to differ.
Thus, some argue that it is inborn, and that there are “special characteristics about the brain’s ability to distinguish faces”. In support of this these they note how much better we are at recognizing a face after a single encounter than we are, for example, in recognizing an individual horse. On the other hand, there are those, and they are probably in the majority, who claim that the gift is an acquired one.
The arguments in favour of this latter view, it must be confessed, are impressive. It is a habit that is acquired soon after birth. Watch, for instance, how a quite young baby recognises his member by sight. Granted that his other senses help – the sound other voice, his sense of smell, the distinctive way she handles him.
But of all these, sight is predominant. Formed at the very beginning of life, the ability to recognize faces quickly becomes an established habit, and one that is, essential for daily living, if not necessarily for survival. How essential and valuable it is we probably do not appreciate until we enc

A.it is unusual for a person to be able to identify a face satisfactorily
B.the ability to recognize faces unhesitatingly is an unusual gift

A.people have the tremendous ability to recognize more than 1,000 faces
B.people don’t think much of the problem of how and why we acquire the ability to recognize and remember faces
C.people don’t realize how essential and valuable it is for them to have the ability to recognize faces

Scattered through the seas of the world are billions of tons of small plants and animals called plankton. Most of these plants and animals are too small for the human eye to see. They drift about lazily with the currents, providing a basic food for many larger animals.
Plankton has been described as the equivalent of the grasses that grow on the dry land continents, and the comparison is an appropriate one. In potential food value however, plankton far outweighs that of the land grasses. One scientist has estimated that while grasses of the world produce about 49 billion tons of valuable carbohydrates each year. The sea’s plankton generates more than twice as much.
Despite its enormous food potential, little effort was made until recently to farm plankton as we farm grasses on land. Now marine scientists have at last begun to study this possibility, especially as the sea’s resources loom even more important as a means of feeding an expanding world population.
No one yet has seriously suggested that “planktonburgers” may soon become popular around the world. As a possible farmed supplementary food source, however, plankton is gaining considerable interest among marine scientists.
One type of plankton that seems to have great harvest possibilities is a tiny shrimplike creature called krill. Growing to two or three inches long, krill provide the major food for the giant blue whale, the largest animal ever to inhabit the Earth. Realizing that this whale may grow 100 feet and weigh 150 tons at maturity, it is not surprising that each one devours more than one ton of krill daily.
Krill swim about just below the surface in huge schools sometimes miles wide, mainly in the cold Antarctic. Because of their pink color, they often appear as a solid reddish mass when viewed from a ship or from the air. Krill are very high in food value. A pound of these crustaceans contains about 460 calories—about the same as shrimp or lobster, to which they are related.
If the krill can feed such huge creatures as whales, many scientists reason, they must certainly be contenders as new food source for humans.
