问题 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.
选项 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
答案 E
解析 根据between A1 and A2结构，排除A、B剩下C、D、E。注意此处，A1：industrialemissions of sulfur dioxide and nitrogen oxides；A2：atmospheric water vapor，不要误认为nitrogenoxides之前的and是between…and结构中的and。C中有两个错误：(1)在GMAT公理中提到，which从不用于作限定性定语从句的引导词；(2)意义不对，which是指“大气水蒸气”；而水蒸气不可能产生高腐蚀性的含氮和含硫酸。D中：(1)同C(1)；(2)have produced用完成时无丝毫根据；(3)which are highly corrosive是不简洁的，应换为：highly corrosive sulfuric and nitric acids。E中：句末的动词不定式是对前面的reactions作修饰，表明“反应的结果”，只不过被between…and结构把两者分隔开了。
