例如:There is a lot of homework to do.
(也可用to be done)There is no time to lose (to be lost).There is no time to lose.
(用to lose可看成for us to lose)
There is no time to be lost.
(用to be lost,谁 lost time不明确)2.在某些“形容词+不定式”做表语的结构中,句子的主语又是动词不定式的逻辑宾语时,这时常用不定式的主动形式表达被动意义。这些形容词有 nice, easy, fit, hard, difficult, important, impossible, pleasant, interesting等。
例如:The book is difficult to read.
The house is comfortable to live in.
He is hard to believe in.
3. 在“too…to do; enough…to…”结构中。如:
The problem is too difficult to work out .
The house is big enough to live in.4. 在“with+n+to do”结构中。
例如:With nothing to do, he lay in bed.With so many exercises to do, I can’t go to the cinema.5. 当不定式的逻辑主语在句中出现时。
例如: I have a letter to type today.
Do you have anything to say?(I是to type的逻辑主语) (you是to say的逻辑主语)1) Do you have anything to send?
你有什么东西要寄吗?
(不定式to send的动作执行者是you)
2) Do you have anything to be sent?
你有什么要(别人)寄的东西吗?
(不定式to be sent的动作执行者是已被省略的someone else)注意比较6. 当不定式隐含在for sb to do结构中时。

hire, blame等。

出售”)
