acid rain

臭老蚊

1. Acid rain and snow result from the chemical reactions between industrial emissions of sulfur dioxide and nitrogen oxides with atmospheric water vapor to produce highly corrosive sulfuric and nitric acids.

(A) with atmospheric water vapor to produce highly corrosive sulfuric and nitric acids

(B) with atmospheric water vapor producing highly corrosive sulfuric and nitric acids

(C) and atmospheric water vapor which has produced highly corrosive sulfuric and nitric acids

(D) and atmospheric water vapor which have produced sulfuric and nitric acids which are highly corrosive（E）

(E) and atmospheric water vapor to produce highly corrosive sulfuric and nitric acids

oa：e

我用排除法得到了e，但我不理解 to produce 为什么用来修饰reaction，而不是主语 acid rain and snow。

请教nn

因为语义上不对。先是化学反应制造了强酸，强酸才形成了酸雨。而不是酸雨制造了强酸。

这句话的结构就是ac ...

同意！               我晚上躺在床上想了想，也应该是这样。谢啦

这句话的结构就是acid rain results from sth (sth = the chemical reaction between a and b to produce c)
