fewer of和less of的用法说明

Fewer和less分别是few和little的比较级形式。要了解less和fewer的区别，就请记住名词有可数不可数之分。

fewer of + pl.[c] (only) 只能跟可数名词复数

less of + [u] / s.[c] 大多数情况下跟不可数名词或者可数名词的单数

less of + pl. [c] = fewer of + pl.[c] 当less of 后面跟可数名词的复数时，其用法等同于 fewer of

fewer of和less of用法实例讲解

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

选项分析：

首先，我们来看这句话的后半部分，D第1个排除，是拿两个名词词组比较，does完全没有意义

然后区别在于用不用定冠词，用的话是用the还是those

those = vehicles 使得比较对象同类，所以要用定冠词those，排除了选项A，B，C

剩下E选项，pollutants是可数名词的复数，也符合less of的语法用法

所以最后答案为E
