问题     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 fascination. But to be fascinated is also, sometimes, to be blind. Several giant dam projects threaten to do more harm than good.
    The lesson from dams is that big is not always beautiful. It doesn’t help that building a big, powerful dam has become a symbol of achievement for nations and people striving to assert themselves. Egypt’s leadership in the Arab world was cemented by the Aswan High Dam. Turkey’s bid for First World status includes the giant Ataturk Dam.
    But big dams tend not to work as intended. The Aswan Dam, for example stopped the Nile flooding but deprived Egypt of the fertile silt that floods left—all in return for a giant reservoir of disease which is now so full of silt that it barely generates electricity.
    And yet, the myth of controlling the waters persists. This week, in the heart of civilized Europe, Slovaks and Hungarians stopped just short of sending in the troops in their contention over a dam on the Danube. The huge complex will probably have all the usual problems of big dams. But Slovakia is bidding for independence from the Czechs, and now needs a dam to prove itself.
    Meanwhile, in India, the World Bank has given the go-ahead to the even more wrong headed Narmada Dam. And the bank has done this even though its advisors say the dam will cause hardship for the powerless and environmental destruction. The benefits are for the powerful, but they are far from guaranteed.
    Proper scientific study of the impacts of dams and of the cost and benefits of controlling water can help to resolve these conflicts. Hydroelectric power and flood control and irrigation are possible without building monster dams. But when you are dealing with myths, it is hard to be either proper, or scientific. It is time that the world learned the lessons of Aswan. You don’t need a dam to be saved.
The third sentence of Para. 1 implies that ______.
选项 A、people would be happy if they shut their eyes to reality
B、the blind could be happier than the sighted
C、over-excited people tend to neglect vital things
D、fascination makes people lose their eyesight
答案C
解析 从文章第1段的内容可知，重大的科技创造中很少有哪个比巨型水坝更让人神往；可能正是因为人类久受早涝之苦，才使得“让洪水听从人的调遣”这种理想如此令人痴迷；但是，令人痴迷有时也会令人盲目；好几个巨型水坝工程有弊大于利的预兆。据此可知，人们往往因为盲目乐观而失去理智，缺乏对关系重大事情的判断力。C项与文章的意思相符，因此C项为正确答案。
