【导读】
不定式的用法
1.作主语.往往放在谓语动词之后,用 e.g.: To see is to believe. __________________
it作形式主语
It is right to give up smoking. 跟他聊天是件很快乐的事.
【导思】_____ with him is a great pleasure
A. To talk B. Talk C. Talked D. To talking
2. 作宾语。作宾语时如果还带有宾语补足语,往往把不定式放在补足语之后,
而用it 作形式宾语。
e.g. He wanted to go.
I find it interesting to study English. 其中 to do 是___________
I didn`t ________ it until you had explained how .
A. manage to do B. managed to do C. manage to have done D. manage doing
3. 坐宾语补足语。 e.g He asked me to do the work with him.
在feel, hear, listen to, look at, notice, observe, see, watch, have, let, make等词后的补足语中,不定式不带 to.
want sb to do , wish sb to do, ask sb to do .
不定式作宾语补足语省略to 的情况有下列口诀:一感二听三让五看半帮助。但是这些句子如果变成被动结构时,就必须带上to e.g. He is often heard __________(sing)the song.
4. 作定语。
I have some books for you to read.
He is looking for a room to live in.
当作定语的不定式所修饰的名词或代词是不定式动作的承受者时,不定式即可以用主动语态,也可以用被动语态。但含义有所不同。
【导思】Have you anything to send? 你有什么东西要(自己)寄吗?
Have you anything to be sent? 你有什么东西_______________寄吗?
5. 作状语,表示目的,原因,结果或条件。
1) I came here to see you 目的
2) We were very excited to find nobody there. ( )
3) He hurried to the school to find nobody there. 结果
4) To look at him , you would like him.( )
6.作表语 My job is to help the patient.
【导练】
1) My chief purpose is _______ the difficulties of the matter .
A. pointing out B. to be pointed C. pointed D. to point out
2) At present, I want to do is ______ the hard job.
A. to finish B. finish C. finished D. finishing
不定式的时态和语态
1. 不定式的一般形式所表示的动作,通常与谓语的动作(状态)同时(或几乎同时)发生,或是在它之后发生。 I saw him go out.
2.谓语表示的动作发生时,不定式表示的动作正在进行,这时要用进行时
I am very glad to be working with you.
3.不定式的动作发生在谓语动词之前,就要用完成时
I’m sorry to have kept you waiting so long.
4.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,不定式一般用被动形式。 He asked to be sent to work in the countryside.

【导读】 but+不定式的用法
1.不定式在介词 but, except, besides, other than 后面时,如果这些介词之前有行为动词do(非助动词)的各种形式时,那么这些介词后面的不定式不带to,否定带to。
2. 当句子的谓语动词是can’t, can’t help, cant’ choose 等结构时,but, except, besides后的不定式to 也省略。
We can’t but admire his bravery. =_________________________________________
He wanted nothing but _________(play) in the park.
