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!
