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

后面对BE选项的解释 完成时态的现在分词结构， having implicated，是错误的用法。遇到这种结构后置修饰前面的

名词时，应该改成对应的定语从句形式：that have/has implicated

之前看了NN的帖子是having done可以做限定修饰前面的名词 不可以非限定修饰 这里怎么直接说是错误用法
having done修饰名词的时候到底什么时候是正确的

这是个高中语法问题，也是个硬性规定。

现在分词完成式是不可以做定语的（就是在名词后面修饰名词），只能做状语。
不能做定语的原因是因为现在分词作后置定语时通常只表示与谓语动作同时或几乎同时发生的动作，而不能先于谓语动作而发生。

前面所说可以做非限定的说法也是错的，因为那些说法的人没有明白状语和定语的区别。

having done如果作定语，只能是作为非限制性的，限制性的一定错，要改成相应的定语从句。
亲是不是记反了？

flonacui

是的 是我记错了 谢谢MM的提醒 可是这里我还是有一个疑问
97. (29753-!-item-!-188;#058&003991)

Industrialization and modern methods of insect controlhave improved the standard of living around

the globe while at the same time they have introduced some 100,000 dangerous chemical

pollutants, having gone virtually unregulated since they were developed more than 50 years ago.

(B) while at the same time introducing some 100,000 dangerous chemical pollutants that have

这里having gone ...还是错的 解释上说目的是做后置定语 但是有做状语的嫌疑

那到底什么情况下非限定修饰是对的
我有点晕了

没有歧义


解释错误


这里having gone就是adverbial modifier没有争议


但是这里句意需要的是noun modifier


adverbial modifier需要apply to the preceding clause（要和主语和动作搭调）


明显的不是主语have gone
