很高兴为你解答.
保证正确率~!
正确答案是:C
【解析】:
leave.doing 让...一直做.
将句子改为主动就是:
If we leave the factory pollutingthe river ,there will be no fish in it soon.
如果我们让工厂一直污染这条河,河里很快就会没有鱼了.
故选C,这里不过是被动语态罢了.
你说选A,分词只能单独用来引导状语( 前面不能加 if 之类的),或者用来做定语,就是不可以作谓语.
如果你选A,要去掉 if ,就是独立主格结构作状语,the factory 是逻辑主语,left polluting the river 是分词,即是:
The factory left polluting the river ,there will be no fish in it soon.
= If the factory is left polluting the river ,,there will be no fish in it soon.
祝开心~!
