LOGICAL GRAMMATICAL 题目释义：Providing initial evidence..., environmentalists…the total amount of pollutant emitted annually by vehicles at O'Hare International Airport is twice…. 考点 比较结构 倍数表达：twice (as much as) sth.; X times adj. than; X times as adj. as; double sth. 选项分析 A. is being错误，删去being后可以直接用as much as that emitted annually。 B. Is多余；比较双方不明确，后面应用补出that；annually放在as…as结构中间成为比较双方共享的东西，造成与前面的annually重复。 C. as…compared to搭配错误；what is annually emitted by all中what的范围大于the total amount of pollutant，而且其实可以简化。 D. Correct；twice后面可以直接接名词，twice as much as也是对的。 E. compared to重复。
