Having been done ,done的区别
____many times,he still couldn't understand it.
A、Having been told B、Told
为什么答案是A,现在分词完成时的被动,B也可以表示完成和被动啊.
同样,还有一道题：The building____last year is a restaurant.
A、having been built B、built
这道题为什么答案又选B了呢?

having been done的原型是having done,我们说下having done和done的区别,他们都能表示被动和完成,但是在做状语是having done表示done的那个动作发生在主句谓语动作之前,有一种顺序关系,而done没有这种关系.这点事最主要的,比如第一个问题,told是发生在understand之前的,所以用A.
其实对于第二个题,不需要区分他们.因为在中学大学阶段,having done是不拿来做定语的,所以直接排除A了.
有什么疑问还可以问我,
