标题: 请教大全164一道比较题

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

Key: E

pollutants在这里加了s,是可数名词,为什么用less去形容呢?

动词+more of/less of+名词

这个结构中more of/less of 修饰前面的动词而非后面的名词

以下是引用FiEdo在2007-8-19 15:34:00的发言:
动词+more of/less of+名词

这个结构中more of/less of 修饰前面的动词而非后面的名词

白勇语法,第七章第七题

那more of/less of在这种情况下是副词?

我知道用less of,不明白E答案 less of certain pollutants than those burning gasoline or diesel fuel,than 后面为什么不是by而是those?一般说来,比较结构的第二个BY 是不省略的呀?

这里those指代vehicles,G里面除了修饰人用fewer,修饰物都用less
