问题      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 of the white cliffs along the south coast of England has always been a problem but it has become more serious iii 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 mm out to be a knockdown home.
The erosion of the white cliffs in the south of England ______
选项 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
答案B
解析 根据第二段第一句话"Erosion of the white cliffs along the south coast of England has always been a problem but it has become more serious in recent years．”可见，海水侵蚀海岸问题由来已久，只不过最近几年变得越来越严重了，已经成了“a threat to the local people"，所以B 为正确答案。
