考研英语重在基础，建议广大考生在了解考研英语大纲的前提下，首先积累英语词汇量，并通过做阅读理解、翻译、写作等练习在词义方面加以提升，然后再考虑学习掌握答题技巧。当然，我们知道英语知识的复习是一个长期积累的过程。让我们跟随何凯文老师的每日一句。所谓：不积跬步，无以至千里;不积小流，无以成江海。坚持就是胜利!坚持也是一种信仰!

Few creations of big technology capture the imagination like giant dams. Perhaps it is humankind’s long suffering at the mercy of flood and drought that makes the ideal of forcing the waters to do our bidding so fascinating. But to be fascinated is also, sometimes, to be blind. Several giant dam projects threaten to do more harm than good.

51. The third sentence of paragraph 1 implies that ________.

[A] people would be happy if they shut their eyes to reality

the blind could be happier than the sighted

[C] over-excited people tend to neglect vital things

[D] fascination makes people lose their eyesight

题型识别：对一句话的推理

思路解析：对一句话的推理就等同于段落推理题;四个选项和原文分别定位;优先选择这段话的主题。

在重大技术所创造的东西中很少能像大型水坝这样让人痴迷的。可能正是因为人类长期遭受旱涝灾害的摆布才使得人们治理江河、供我驱策的理想如 此令人痴迷。但让人着迷有时也就使人盲目。有几个巨型大坝项目就有弊大于利的危险。

选项分析：能够和段落主题相关的选项就只能是：[C] over-excited people tend to neglect vital things

其他选项都只是对这个句子字面含义的胡乱解读，而不是对这段话的把握。
