1.        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）

(E) less of certain pollutants than those burning gasoline or diesel fuel

按照GMAT语法, pollutants是可数名词, 不应该用less来修饰呀, 这题为啥选E?? 请NN指教, 谢谢!!!

这里的less是名词哦~~~

去查查字典吧~more 和less都可以做名词。

less

[les]
n.
较少, 较小

more
[mCr)]
adj.
更多的
n.
更多

比如说

I ate more of apples than did you.

你看看哦一般adj.后面不加of的，只有名词才加。

如果这道题你想用adj.做比较的话就应该是：

emit fewer certain pollutants than ...
