having been +V-ed 和v-ed做状语的区别
Not having completed the programme,they have to stay there for another two weeks.
when completed ,the museum will be open to the public next year.
这里的completed 和having completed 可以互换吗?
都是表被动完成吧?

不可以互换的.
第一句中Not having completed the programme的have completed 是现在完成时,主语是they,并非被动.
第二句中when completed 的completed才是被动.

having been +V-ed 和v-ed做状语的区别 V-ed和having been v-ed的区别 have been v+ed / have v+ed 的区别关于非谓语动词的用法having done 和v-ed的区别是什么? v-ing作状语的时候,什么时候用原型v-ing,什么时候用完成时having v-ed啊? v-ing做状语,主句谓语动词是过去式的话,状语为having done,和v-ing的区别 have been+v.ed是什么时态,我看有说是现在完成时,那么,它和have+v.ed有没有什么区别,哪位知道给说说 V-ing 形式做定语和做状语的区别可否给一些以V.ed作后置定语 v.ing形容词 v.ed形容词姐V.ing 做宾语 to do做宾语的动词呢?学学 -ing、-ed做伴随状语的问题英语中V-ING ,V-ED 与不定式放在句首时的区别谢谢了, keep sb./sth.+V-ed的用法?
