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。
