请教一个语法题哈，谢谢大家~

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
此题为什么不可以用fewer?

pollutants不是可数吗？

不解.我以为选B. 不是么?

valerialam

选E的。

这道题可以看出答案是E.

好像在那里看到过解释,不是less,而是"less of",意思是较少的意思, 与few of 不是一个概念.

不知道是那NN的解释如下:

less - a smaller amount

few - not many, not enough

我觉得 "less of certain pollutants" 指 "更少量的污染物"

而 "fewer of certain pollutants" 指 "更少种类的污染物",

显然, less of 更符合题意.

不知道对你有没有帮助.

less of 作为副词 修饰emit， 而不是pollutants， 这个可以认为是固定搭配 /v/+less of/more of + /n/ 理 解为在“更小/大程度上” 修饰动词 所以是less of

Reference： 白勇语法 比较结构

valerialam

还是不太明白啊。。。
