Diesel engines burn as much as 30 percent less fuel than gasoline engines of comparable size, as well as emitting far less carbon dioxide gas and far fewer of the other gases 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 gases that have

(B) of comparable size, as well as emit far less carbon dioxide gas and far fewer of the other gases having

(C) of comparable size, and also they emit far fewer carbon dioxide and other gases that have

(D) that have a comparable size, and also they emit far less carbon dioxide gas and other gases that have

(E) that have a comparable size, as well as emitting far fewer carbon dioxide and other gases having

答案是a 为何不选b? as well as 作为连词还是可以像while一样引导伴随？

谢谢

同问！谢谢。

怀疑as well as不能链接谓语。这里A只是伴随，B的having been似乎不对。

同问，有没有NN解答一下。另外having been 和that have been在这里有什么区别吗？

A DO STH, AS WELL AS DOING C

固顶搭配.

as well as 不能做连词.

我觉得having been done这种用法一般来说应该是不对的， 因为直接用done就可以表达出被动和完成这两层意思了，所以要么用sth done 要么用sth that have been done.
