Although schistosomiasis is not often fatal, “it is so debilitating that it has become an economic” drain on many developing countries. (A) it is so debilitating that it has become an economic (B) it is of such debilitation, it has become an economical (C) so debilitating is it as to become an economic (D) such is its debilitation, it becomes an economical (E) there is so much debilitation that it has become an economical 答案是A B选项OG解释说the noun debilitation creates an awkward, wordy alternative and a slight change in meaning; 请问为什么debilitation不合适？作者: lpilikeit 时间: 2010-8-26 16:49
简单的说 OG里有一个不成文的规定就是动词由于名词 形容词优于名词 OG在定义有效的句子中的一条就是简洁，it is of such debilitation其实是用了名词的形式来表达形容词的意思：它是那么的会使人衰弱，为什么不直接用形容词去表达呢？这就跟用it is of such importance来说it is so important,当然后者更简洁有效，表达也直接强烈。也许可以用名词，但绝对不是最优选择。 希望对你有帮助作者: 舟楫 时间: 2010-8-26 17:35
