问几个新概念英语第二册的问题
I promise that the matter will (be taken care of).
后面为什么有了will还有过去分词?be为什么会出现,明明take care of是动作啊?will不能直接加take care of?
If he had worked harder,he (would have succeeded).
后面为什么要有have succeeded?would后面怎么会加have?
She did not remember (having met) him before.
中间填的having后面为什么不加met的原形?中间能填 to meet吗?

答案

那里不是过去分词
i promise that the matter will (be taken care of).我保证事情会得到妥善的处理 .这里,事情是被!处理,所以要用被动,will后面要跟动词原形 所以是will be taken……
If he had worked harder,he (would have succeeded).
后面为什么要有have succeeded?would后面怎么会加have?
这个是虚拟语气 if条件句对过去进行虚拟"如果他（过去）努力的话,他就会成功"
She did not remember (having met) him before.
中间填的having后面为什么不加met的原形?中间能填 to meet吗?
这个 remember后面有两种解法 借to do 记得做某事 接doing 记得做过某事 原句的意思是“他不记得他以前曾经见过他”所以用doing,不能换成to meet 、have后面用过去分词 have done
还有问题吗
