1.不定式的时态及语态
时态 主动 被动 意义 例句 语态
一般 to do to be done 与谓语动词同时发生或以后发生 I’m glad to see you. 当不定式逻辑上的主语是这个不定式所表示的动作的承受者时,不定式须用被动形式。如:He asked to be sent to work in Tibet.
This book is said to have been translated into many languages.
进行 to be doing
表示谓语的动作(情况)发生时,不定式表示的动作正在进行 He pretended to be reading a book when I came in.
完成 to have done to have been done 先于谓语动作发生 We seem to have met each other before.
完成进行 to have been doing
先于谓语动作发生而又延续到谓语动作发生后 He is said to have been studying abroad,but I don’t know which country he is studying in.
2.不定式的句法功能
1)作主语:
To finish the work in ten minutes is very hard.在十分钟内完成这项工作很难。
动词不定式短语作主语时,常用it作形式主语,例如上面一句可用如下形式:
It is very hard to finish the work in ten minutes.
2)作表语:
Her job is to clean the hall.她的工作就是打扫大厅。
