文档介绍：(4)作宾语补足语:
在复合宾语中,动词不定式可充当宾语补足语,如下动词常跟这种复合宾语:want, wish, ask, tell, order, beg, permit, help, advise, persuade, allow, prepare, cause, force, call on, wait for, invite.
此外,介词有时也与这种复合宾语连用,如:
With a lot of work to do, he didn't go to the cinema.
有些动词如make, let, see, watch, hear, feel, have等与不带有to的不定式连用,但改为被动语态时,不定式要加to, 如:
I saw him cross the road.
He was seen to cross the road.
(5)作定语:
动词不定式作定语,放在所修饰的名词或代词后。与所修饰名词有如下关系:
①动宾关系:
I have a meeting to attend.
注意:不定式为不及物动词时,所修饰的名词如果是地点、工具等,应有必要的介词,如:
He found a good house to live in.
The child has nothing to worry about.
What did you open it with?
如果不定式修饰time, place, way,可以省略介词:
He has no place to live.
This is the best way to work out this problem.
如果不定式所修饰名词是不定式动作承受者,不定式可用主动式也可用被动式:
Have you got anything to send?
Have you got anything to be sent?
②说明所修饰名词的内容:
We have made a plan to finish the work.
③被修饰名词是不定式逻辑主语:
He is the first to get here.
(6)作状语:
①表目的:
He worked day and night to get the money.
She sold her hair to buy the watch chain.
注意不定式放句首时,逻辑主语与句子主语要一致:
wrong:To save money, every means has been tried.
right:To save money, he has tried every means.
wrong:To learn English well, a dictionary
