我选 A
首先,这是一个句子,已经有谓语了,所以要填一个非谓语,故排除 D
其次,to do 不定式引导目的状语,有already,证明不是目的,故排除 C
最后,非谓语动词表示的动作与主语it是主动关系,故选A~
结构上分析
一个句子一个谓语动词
排除BD
意思上分析
C意思不对
选A
having suffered现在分词作状语
关键词:such、already说明是形容词、被动语态。主句it may now be too late to clean up the river说明污染已形成,故为现在完成式。选项A(是不是打错了……应该是:Having suffered吧……)
A,现在完成时,且是主动形式。
A:Having sufferer.
表示伴随。
