大全164.
Because natural gas is composed mostly of methane, a simple hydrocarbon, vehicles powered by natural gas emit less of certain pollutants than the burning of gasoline or diesel fuel.
(A) less of certain pollutants than the burning of gasoline or diesel fuel
(B) fewer of certain pollutants than burning gasoline or diesel fuel do
(C) less of certain pollutants than gasoline or diesel fuel
(D) fewer of certain pollutants than does burning gasoline or diesel fuel
(E) less of certain pollutants than those burning gasoline or diesel fuel
我是选的d,对于less看了以前的帖子我认为是n.但是对于后面那个burning gasoline or diesel fuel为什么是复数啊??是什么意思呢??貌似比较简单啊....可是偶想了两个晚上都木有想通
你的E答案不全,这句话是vehicles和vehicles(用those指代了)比。
E) less of certain pollutants than those burning gasoline or diesel fuel
不知道这次说明白了没。

这道题目主要考比较
vehicles 和后面的those对应 同时than 后面省略了助动词
