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

　　这道题目的考查对象为between…and…这一常见的固定搭配，用来连接两个名词或名词短语，本题对考生的干扰主要在于sulfur dioxide和nitrogen oxides中间已经出现了一个and，有些考生就想到GMAT语法要求句子简明，那么连用and肯定不合适，首先将C，D和E排除掉了。但是如果用with，整句话逻辑关系不通，这个错误当然要比用词重复严重得多，相比之下还是选择使语意合乎逻辑的选项，正确答案为E。我们不选C和D的理由并不是由于句子不简洁，而是其逻辑关系有误。
