有关比较等级重要考点

1. It is reported that the United States uses _________ energy as the whole of Europe. (广西卷)

A. as twice             B. twice much         C. twice much as       D. twice as much

【解析】答案选D。由energy后的as可知，此题是考查as…as…结构。根据英语语法习惯，修饰as…as…结构的副词只能置于as…as…结构之前，不能置于其中。又如：She went out with a man twice as old as her. 她和一个年龄比她大一倍的男子来往。It cost three times as much as I had expected. 它花的钱比我预期的多两倍。

2. He speaks English indeed, but of course not _________a native speaker. (上海卷)

A. as fluent as        B. more fluent than     C. so fluently as       D. much fluently than

【解析】答案选C。因为修饰动词speaks要用副词，排除A和B；又因为than只能用于比较级后而不能位于原级后，排除D。句意是：他的英语讲得的确不错，不过，当然不如英语本族人讲得流利。
