倍数表达：twice (as much as) sth.; X times adj. than; X times as adj. as; double sth.

twice (as much as) sth（as much as 可省略）； compare和倍数不同时存在； compare to是"比作、比喻为"不是比较

1、twice(as much as)...

that指代the total amount of pollutant

做题时候脑抽了 感觉 twice that 中间少了点什么.....其实不少 twice 可以直接跟名词的 twice the weight twice the height that 指代 the total amount of pollutant

twice (as much as) sth.; X times adj. than; X times as adj. as; double sth.

that 可以做谓语

Correct；twice后面可以直接接名词，twice as much as也是对的

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。

做题时因为觉得是amount，as much as 是错误的，事实上，应该twice as much as 也可以是正确的，前三个选项错误，各自有原因。
