问题     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.

选项

答案     以阿斯旺大坝为例,它挡住了尼罗河的洪水,但也使埃及失去了洪水冲积的肥沃土壤,换回来的却是一个病态的大水库。现在水库积满泥沙,几乎不能用于发电了。

解析
