主动语态
被动语态(be done)
是动词要考虑
引言:英语中语气、语态的变化都是通过动词变形实现的,所以掌握动词的变形举足轻重。切记:要把示意动词充当谓语和非谓语动词要分开,非谓语顾名思义已经不是谓语动词了,所以它的用法和变形与动词时态是不一样的!
非谓语类型 | 不定式(to do) 目的,将来 | 动名词(现在分词) (doing)主动,进行 | 过去分词 (done)过去,完成 |
充当句子成分 | 主语,宾语,定语,表语,状语,补语 | 主语,宾语,定语,表语,状语,补语 | 定语,状语,补语,表语 |
一般式 | to do / to be done(被动) | doing/ being done(被动) | done |
完成式 | to have done/ to have been done | having done/ having been done(被动) | |
否定式 | Not to do | Not doing | Not done |
