    People living on parts of the south coast of England face a serious problem. In 1933, the owners of a large hotel and of several houses discovered, to their surprise that their gardens had disappeared overnight. The sea had eaten into the soft limestone cliff (悬崖) on which they had been built. While ex??perts 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 aban??doned 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 eaten 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 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 ar??ea of hard rock, which will not be eaten as limestone is. Mean??while, if you want to buy a cheap house with an uncertain fu??ture, apply to a house agent in one of the threatened areas on the south coast of England. You can get a house for a knock??down price but it may turn out to be a knockdown home.

    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’ short of knowledge.

    C. The washing-away of limestone cliff.

    D. The disappearance of hotels, houses and gardens.

    The erosion of the white cliffs in the south of England ________.

    A. will soon become a problem for people living in central England

    B. has now become a threat to the local residents

    C. can be stopped if proper measures are taken

    D. is quickly changing the map of England

    The experts’ study on the problem of erosion can ________.

    A. warn people whose homes are in danger

    B. provide an effective way to slow it down

    C. help to its eventual solution

    D. lead to its eventual solution(www.nmet168.com)

    It is not feasible to build sea defenses to protect against erosion because ________.

    A. house agents along the coast do not support the idea

    B. it is too costly and will endanger neighboring areas

    C. the government is too slow in taking action

    D. they will be easily knocked down by waves and currents
