prep--可数问题，请指教！（保证不是重复问！）

Diesel engines burn as much as 30% less fuel than gasoline engines of comparable size, as well as emitting far less carbon dioxide gas and far fewer of the other gasses that have been implicated in global warming.
A of comparable size, as well as emitting far less carbon dioxide gas and far fewer of the other gasses that have
B of comparable size, as well as emit far less carbon dioxide gas and far fewer of the other gasses having
C of comparable size, and also they emit far fewer carbon dioxide and other gasses that have
D that have a comparable size, and also they emit far fewer of the other gasses having
E that have a comparable size, as well as emitting far fewer of the other gasses having

选A, 我知道了
可请问，怎么可以carbon dioxide gas不可数，用less，other gases可数，用few。。。
不都是gas嘛。。。

虽然楼上说的很好了，这里再补充一点Ron的看法
the most straightforward thing in choice D:
"far less carbon dioxide and other gases that have..." appears to indicate that the engines emit other gases (not LESS OF those other gases).
note that you can't read this as "less (carbon dioxide ... and other gases...)", either -- i.e., with "less" applying to both things -- because "less other gases" doesn't make sense.

you could have "fewer gases" (= not as many different kinds), or "less OF the gases" (= a smaller total quantity)... but not "less gases".

差了下prep语法笔记，这是里面的注解，希望对你有 用哦：
    A正确，二氧化碳气体是不可数名词，因此对应使用 far less carbon dioxide gas，表示二氧化碳排
放“量”的少；the other gases 本身使用了复数形式 gases，表示其他气体的种类，因此对应使用修饰可数名词的 fewer，fewer of the other gases 表示其他气体排放“种类”的少。
