having suffered such heavy pollution already,it may now be too late to clean up the river.一般使用分词要看它和主语的关系,也就是说是主动还是被动.但这句话用having suffered 是什么原因
我认为：主语it 是代表river 的,而river 与suffered polluted之间是被动的关系.再加上完成时态就成了：having suffered 了
有一个很好的句子就是：Seen from the mountain ,the village is very beautiful!
从小山上看去,这个村庄美丽极了!
所以有的时候多记些,这样的句子对做题是很有帮助的!

就是已经被这么严重得污染了，表已经被污染了。

这是完成时

有遭受如此的重污染已经，它现在可能是太晚到干净的在河上面。
应该是这样

it may now be too late to clean up the river本该是it may now be too late FOR US to clean up the river.

having suffered是一个伴随状语,它表示river已经而且现在仍然在受到污染.就是这个意思.

Having suffered such a heavy loss和suffered such a --的区别 ——such a heavy loss in the earthquake,they got help from all over the world.应该选择suffer suffered还是having suffered? 英语选择空such heavy loss in the hurricane,the farmer didnot expect to have a good harvestA.suffering B.having suffered C,suffered 正确是b,为什么 having suffered such heavy pollution already,it may now be too late to clean up the river.一般使用分词要看它和主语的关系,也就是说是主动还是被动.但这句话用having suffered 是什么原因 ——such heavy pollution already,it may now be too late to clean up the river.A:Having sufferer B:Suffered from C:To suffer D:suffer fromA的应该是suffered ( )such heavy pollution today,it may now be too late to clean up the river.A Having suffered B SufferingC To suffer D Suffered希望各位可以给出详细的解答,我这个人钻牛角尖……谢谢 -----such heavy pollution already,it may now be too late to clean up the river A having suffered BC to suffer D suffered A 河道和污染是被动的关系,看了一些相关的解释不太明白. ___ such a heavy loss,the businessman didn't have the courage to go on.A.Having suffered B.suffering C.TO suffer D.suffered希望能得到详细的答案,为什么选A,不选其它选项的原因. （） such heavy loss,the businessman didn't have the courage to go on.1.Having suffered 2.Suff（） such heavy loss,the businessman didn't have the courage to go on.1.Having suffered2.Suffering 3.To suffer4.Suffered 为什么选A啊, 搞不懂这个句子,帮忙分析下[having suffered] such heavy pollution already, it may now be too late to clean up the river.一般使用分词要看它和主语的关系是主动还是被动不是吗?那么这句话用 having suffered 是什么 having suffered from heart trouble for years.为什么不用suffering （） such heavy loss,the businessman didn't have the courage to go on.1.Having suffered2.Suffering 3.To suffer4.Suffered分词的动作或状态分词的动作或状态先于主句谓语动词发生时, Having suffered from cancer,Jim died on May 5th,2009.开头能否用Having been suffered? ______from heart trouble for years,Professsor Wang has to take some medicine with him wherever he：Suffered B：Suffering C：Having suffered D：Being suffered I can't imagine such a little girl ______such a terrible disease.A suffering fromB sufferingC suffered fromD suffered 过去分词作状语问题Having been suffered such heavy pollutin already,it may now be too late to clean up the river.Having been told many times ,he still couldn't understand.为什么第一句要去掉been 第二句不用? Having suffered such heavy loss,the businessman didn't have the courage to go on.有疑问?那主句谓语是一般过去式,但boss与suffer是主动关系,suffer发生在主句前.为何不用过去完成时?而用having Suffer two英语疑问,while are关于句式结构1.Having suffered such heavy pollution already,it may now be too late to clear up the river.Q：后面分句的主语是it还是river?如果是it,那不是和前面的having主语不一致了?2.Give this to
