have been done和be done还有情态动词+be done这三个有什么区别?都应该在什么句子里用或语境里用?最好能举几个例子,谢谢!
那么be done在现在时的时候只能有被动语态吗?I'm broken free from this memories. 这是什么语态?
have done 又是怎么用的?
谢谢!
be done 这种结构有两种解读
(1) 解读就是,一般现在时态的被动语态 和一般过去时态被动,例如
A :一般现在时态被动语态:
English is spoken by many people in the world
B: 一般过去时态被动语态:
The cup was broken by Tom last night
(2)解读就是,形容词化的过去分词作表语,这里已经不是一个过去分词看待,而是看成一个形容词作表语,例如
Tom was so excited to heard that
汤姆听到那事时非常激动。
They were excited with joy at the success.
他们为成功而欣喜若狂。
We’re only too pleased to help.
我们非常愿意帮忙
如果满意,请立即采纳,谢谢!
