Passage One
Questions 11 to 15 are based on the following passage:

　　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.

　　A) lead to its eventual solution
　　B) provide an effective way to slow it down
　　C) help to prevent it from worsening

14. It is not feasible to build sea defenses to protect against erosion because _____________.
　　A) it is too costly and will endanger neighbouring areas
　　B) the government is too slow in taking action
　　C) they will be easily knocked down by waves and currents
　　D) house agents along the coast do not support the idea

答案:
翻译：英格兰南海白色悬崖峭壁的腐蚀一直是个问题，不过最近几年变得更为严重了。
　　11.问题的原因。对应于The sea had eaten into the soft limestone cliffs on which they had been built.答案是D，eaten into和washing-away属于是同意替换。
　　12.光看题目不知道题目问的是什么，所以看一下选项，定位在第二段。A：central England还不至于。C：第三段说了阻止侵蚀是不可能的。D：quickly changing也没有那么夸张。答案选B。
　　13.定位在第二段最后一句：只是预测，所以答案是D。
　　14.定位在第三段。Impossible后面这一句就是答案。答案是A，对这句话的概括。
　　15.定位在最后一句：你可用最低的价格买到一栋房子，但它可能也不堪一击的房子。所以推断答案是A：要考虑潜在的危险。
　　文章有三段，第一段有一个题，第二段和第三段分别有两个题，这种格式要留意一下。
