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

 是说，rain and snow result from (...reactions) 然后to preduce...修饰reactions？

感觉后面to引导的修饰挺奇怪的，大家能给我讲讲么？

小女子先拜谢~~

to引导的是状语。

仔细看一下还是比较简单的，两个短语：industrial emissions of sulfur dioxide and nitrogen oxides，二氧化硫和氧化氮都是工业emissions；chemical reactions between industrial emissions and atmospheric water vapor，化学反应是发生在工业emissions和水之间的。这时候就清楚了，to做状语

我所理解的本句大意是：酸雨和酸雪是由工业排放的二氧化硫、氮氧化物和空气中的水蒸气进行的化学反应的结果，二氧化硫、氮氧化物和空气中的水蒸气作用产生强腐蚀硫酸和硝酸液。

between ... and ... 排除A, B 选项；C 项，which has 修饰water vapor, 与后面的产生酸逻辑不通；D项的which have... which are.... 太繁琐，错；那么E 项成为最佳选择。
