一、阅读理解（共 4 道试题，共 40 分。）V 1.     People living on parts of the south coast of England face a serious problem. In 1993, the owners of a large hotel and of several houses discovered, to their horror, that their gardens had disappeared overnight. The sea had eaten into the soft limestone cliffs on which they had been built. While experts were studying the problem, the hotel and several houses disappeared altogether, sliding down the cliff and into the sea.
    Erosion（侵蚀）of the white cliffs along the south coast of England has always been a problem but it has become more serious in recent years. Dozens of homes have had to be abandoned as the sea has crept farther and farther inland. Experts have studied the areas most affected and have drawn up a map for local people, forecasting the year in which their homes will be swallowed up by the hungry sea.
    Angry owners have called on the Government to erect sea defenses to protect their homes. Government surveyors have pointed out that in most cases, this is impossible. New sea walls would cost hundreds of millions of pounds and would merely make the waves and currents go further along the coast, shifting the problem from one area to another. The danger is likely to continue, they say, until the waves reach an inland area of hard rock which will not be eaten as limestone is. Meanwhile, if you want to buy a cheap house with an uncertain future, apply to a house agent in one of the threatened areas on the south coast of England. You can get a house for a knockdown price but it may turn out to be a knockdown home.
1). What is the cause of the problem that people living on parts of the south coast of England face?
A. The rising of the sea level.
B. The experts’ lack of knowledge.
C. The washing-away of limestone cliffs

D. The disappearance of hotels, houses and gardens.

      满分：2  分
3). The experts’ study on the problem of erosion to __________.
A. warn people whose homes are in danger
B. provide an effective way to slow it down
C. head to its eventual solution
D. lead to its eventual solution
      满分：2  分
4). It is not feasible to build sea defenses to protect against erosion because __________.

B. it is too costly and will endanger neighbouring areas

C. the government is too slow in taking action

2.  If we were asked exactly what we were doing a year ago, we should probably have to say that we could not remember. But if we had kept a book and had written in it and account of what we did each day, we should be able to give an answer to the question.
    It is the same in history. Many things have been forgotten because we do not have any written account of them. Sometimes men did keep a record of the most important happenings in their country, but often it was destroyed by fire or in a war. Sometimes there was never any written record at all because the people of that time and place did not know how to write. For example, we know a good deal about the people who lived in China 4,000 years ago, because they could write and leave written records for those who lived after them. But we know almost nothing about the people who lived even 200 years ago in central Africa, because they had not learned to write.
    Sometimes, of course, even if the people cannot write, they may know something of the past. They have heard about it from older people, and often songs and dances and stories have been made about the most important happenings, and these have been sung and acted and told for many generations. For most people are proud to tell what their fathers did in the past. This we may call “remembered history”. Some of it has now been written down. It is not so exact or so valuable to us as written history is, because words are much more easily changed when used again and again in speech than when copied in writing. But where there are no written records, such spoken stories are often very helpful.

1).  Which of the following ideas is not suggested in the passage?
A. “Remembered history”, compared with written history, is less reliable.
B. Written records of the past play the most important role in our learning of the human history.

C. A written account of our daily activities helps us to be able to answer many questions.

D. Where there are no written records, there is no history.
      满分：2  分
2). We know very little about the central Africa 200 years ago because _______.
A.  there was nothing worth being written down at that time
B. the people there ignored the importance of keeping a record

C. the written records were perhaps destroyed by a fire

D.  the people there did not know how to write
      满分：2  分
3). “Remembered history” refers to _______.
A. history based on a person’s imagination
B. stories of important happenings passed down from mouth to mouth

C. songs and dances about the most important events

D. both B and C
      满分：2  分
4). “Remembered history” is regarded as valuable only when _______.
A. it is written down
B. no written account is available

C. it proves to be true     
D. people are interested in it
      满分：2  分
5). The passage suggests that we could have learned much more about our past than we do now if the ancient people had _______.
A. kept a written record of every past event
B.  not burnt their written records in wars

C. told exact stories of the most important happenings

D. made more songs and dances

3.      In the last 500 years, nothing about people—not their clothes, ideas, or languages—has changed as much as what they eat. The original chocolate drink was made from the seeds of the cocoa tree by South American Indians. The Spanish introduced it to the rest of the world during the 1500’s. And although it was very expensive, it quickly became fashionable. In London, shops where chocolate drinks were served became important meeting places. Some still exist today.
The potato is also from the new world. Around 1600, the Spanish brought it from Peru to Europe, where it soon was widely grown. Ireland became so dependent on it that thousands of Irish people starved when the crop failed during the “potato famine” of 1845-1846, and thousands more were forced to leave their motherland and move to America.
There are many other foods that have traveled from South American to the Old World. But some others went in the opposite direction. Brazil is now the world’s largest grower of coffee, and coffee is an important crop in Colombia and other South American countries. But it is native to Ethiopia, a country in Africa. It was first made into a drink by Arabs during the 1400’s.
    According to an Arabic legend, coffee was discovered when a person named Kaldi noticed that his goats were attracted to the red berried on a coffee bush. He tried one and experienced the wide-awake feeling that one–third of the world’s population now starts the day with.
1). According to the passage, which of the following has changed the most in the last 500 years?
A. Food
B. Clothing
C. Ideas
D. Languages

4.  When Mrs. Joseph Groeger died recently in Vienna, Austria, people asked the obvious, “Why did she live to be 107?” Answers were provided by a survey conducted among 148 Viennese men and women who had reached the age of 100. Somewhat surprising was the fact that the majority had lived most of their lives in cities. In spite of the city’s image as an unhealthy place, city living often provides benefits that county living can lack. One factor seems to be important to the longevity (长寿) of those interviewed.
    This factor is exercise. In the cities it is often faster to walk short distances than to wait for a bus. Even taking public transportation often requires some walking. Smaller apartment houses have no elevators (电梯), and so people must climb stairs. City people can usually walk to local supermarkets. Since parking spaces are hard to find, there is often no alternative to walking.
    On the other hand, those who live in the country and suburbs do not have to walk every day. In fact, the opposite is often true. To go to school, work, or almost anywhere else, they must ride in cars.

1). The Vienna survey may help to explain _______.
A. the complaints of people in apartment houses

B. the cause of Mrs. Groeger’s death

C. the longevity of people like Mrs. Groeger

D. the image of cities in general
