1. The most thrilling explanation is, unfortunately, a little defective. Some economists argue that powerful structural changes in the world have upended the old economic models that were based upon the historical link between growth and inflation.
很不幸，这最令人震惊的解释有一点缺陷。一些经济学家认为世界经济结构的强有力的变化已经结束了那个以经济增长和通货膨胀的历史关联为基础的旧的经济模式。
2. 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.
例如，阿斯旺大坝使得尼罗河不再洪水泛滥，但是它也夺去了埃及以前 所享有的洪水留下的肥沃淤泥--这些换宋的就是这么个疾病滋生的水库，现在这个水库积满了淤泥，几乎不能发电了。
