Book 7 unit 1 Living well The Fourth and Fifth Periods Grammar：动词不定式
I. 动词不定式由“to+动词原形”构成(在某些情况下to也可省略)。它可以在句中作主语、宾语、表语、定语、状语、补足语等,但不能作谓语。不定式可以有自己的逻辑主语,即for/of sb. to do sth.
1. 不定式作主语
To finish this report took him a week. To see is to believe.
2. 不定式作表语
My job is to help the poor person. What I would suggest is to put off the meeting.
3. 不定式作宾语
He pretended to have read the book when I asked him about it.
I decided to ask for my money back.
4. 不定式作宾补
I would like you to help me with my English exercises.
1) 带to的不定式作宾补。很多动词如: allow, order, force, permit, tell, want, wish, forbid, advise, persuade, warn等后面作宾补的不定式都带to。
如: He didn’t allow us to smoke in his house.
2) 有些动词须用不带to的不定式作宾补。使役动词make, have, let;感官动词see, watch, observe, hear, listen to, notice等后面作宾补的不定式不带to。
如: He made a face and made everybody laugh.
注意: 如果上述结构变为被动语态,不定式就由原来的宾语补足语变为主语补足语,此时第2类动词(let, have无被动语态)后原来不带to的不定式要加to。
如: He was seen to go upstairs. They were made to work 13 hours a day.
5.不定式作定语
Do you have anything to say on the question
注意: 作定语的不定式如果是不及物动词,或者不定式所修饰的名词或代词是地点、工具等,不定式后面须有相应的介词。如；
He is looking for a room to live in. There is nothing to worry about.
6. 不定式作状语
I stayed there to see what would happen.
We were very excited to hear the news.
7. 疑问词+动词不定式：
不定式和疑问词whether, what, which, whom, where, when, how, why等连用可以在句中起名词的作用，通常跟在tell, know, show, decide, learn, wonder, explain, advise, teach, discuss, find out等动词后面作宾语，有时也可以充当主语、表语等。如：
On hearing the news, he didn’t know whether to laugh or to cry.
When to hold the meeting has not decided.
The most important problem is how to get so much money.
介词后一般不直接接不定式，但可以接疑问词+不定式短语作宾语。如：
Mary gave some advice on how to learn English.
I have no idea of how to do it.
II动词不定式有时态和语态的变化，通常有下表中的几种形式（以do为例）：
主动式 被动式
一般式 to do to be done
完成式 to have done to have been done
进行式 to be doing /
完成进行式 to have been doing /
1) 不定式的一般式所表示的动作通常与主要谓语的动作同时或几乎同时发生，或是在它之后发生。如：
They invited us to go there this summer. He stood aside for me to pass.
2) 不定式的完成式所表示的动作在谓语所表示的动作之前发生，它在句中可作表语、状语、宾语，有时也可作主语、定语等。如：
She seemed to have heard about this matter. I am sorry to have kept you waiting so long.
I meant to have told you about it, but I happened to have an important thing to do.
It has been an honor for me to have traveled so much in your country.
3) 不定式的进行式表示正在进行的与谓语动词同时发生的动作。它在句中可以用作除谓语以外的所有成分。如：
It’s nice of you to be helping us these days. He pretended to be listening to the teacher carefully.
We didn’t expect you to be waiting for us here.
4) 如果不定式表示的动作是谓语所表示时间之前一直进行的动作，就需要用完成进行式。如：
They are said to have been working in Tibet for 20 years.
We are happy to have been helping each other these days.
5)动词不定式的否定形式是由not或never加不定式构成。如：
Try not to be late again next time. He wished us never to meet her again.
