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 正确答案是A. 但是emit 应该是和burn并列阿，那么emitting就不对了吧，虽然我也觉得B最后的having肯定不好。难道是as well as 可以有这样子的并列吗？ 请指教。谢谢！ |
