英语阅读题,帮忙看下是答案印错还是我错?
People living on part of the south coast of England face a serious problem. 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.

答案DACCB, 我选的DBABD

1,答案是D,这个没什么问题.
2,正确答案是A,你看第二段第一句说的是白色悬崖的侵蚀已经变成一个问题,后面紧跟一个but it ,说明将来会带来更多的问题.
3,正确答案是C,看第二段那段话说的是专家们已经为当地老百姓草拟了一张地图,预测在未来几年内大海可能会侵蚀到的地方.所以说专家们的那些报告也只是有助于解决问题,而不是D选项中绝对的意思.
4,正确答案的确是C,这题很容易选成B,因为按原文的意思就是政府的调查员说建海防墙不仅造价太贵,而且解决不了问题,只会将侵蚀问题转移到另一个地区.但是这不是这道题的答案,如果题目是：按照政府的说法,建海防堤不合理的原因是（）,那么答案就是B.但这道题你还要看最后那句until后面跟的那段,就不难得出是因为政府的人行动效率不行,不然不会等到海水侵蚀到内陆才开始紧张.
5,正确答案是B,细读文章最后一段就可以看出,作者最后用了调侃的口吻再告诉读者,如果你能在英格兰南海岸买一套价格很便宜的房子,那么你得到的可能不仅仅是一个不可预知的未来,伴随着这爆炸性的低价,可能得到的是一座极容易垮掉的房子.意思就是告诉人们,如果碰到那种地产商说什么在南海岸可以买到廉价的房子,那么这是极其危险的,因为海岸的被侵蚀,也就是告诫人们不要被那些无良的房地产商欺骗.
