Grammar 1
不定式的用法
不定式的句法功能
1. 作主语: 往往放在谓语动词之后, 用
it 作形式主语。
e.g:
To see is to believe.
It is right to give up smoking.
_____ with him is a great pleasure.
A. To talk B.Talk
C. Talked D. To talking
本题考察动词不定式做主语的情况, 动词不定式做主语, 谓语动词用单数形式, 其他三项都不能用来做主语。 本句的意思是: 跟他聊天是件很快乐的事。
A
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.
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
本句的意思是：直到你解释了如何去做我才能做到成功。manage 后面用to do 形式作宾语。
A
3. 做宾语补足语
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。
The government calls on us _______ our production.
A. Increased B. increasing
C. Increase D. to increase
本句意思是: 政府号召我们增加生产。本题考察动词不定式做宾语补足语, 通常用语及物动词和一些动词短语之后。如: want sb to do, wish sb to do, ask sb to do.
D
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.:
I often hear him sing the song.
He is often heard to sing the song.
4. 作定语
I have some books for you to read.
当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不定式动作的地点、工具等时, 不定式后面必须有相应的介词。
e.g.：
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。
试比较：
Have you anything to send?
你有什么东西要（自己）寄吗？
Have you anything to be sent?
你有什么东西要（我或别人）寄吗？
At last, they found a house _________.
A. to leave his things with
B. to leave his things in
C. leaving his things in
D. leaving his things
本句的意思是：最后他们终于找到了一间可以存放东西的屋子。当动词不定式所修饰的名词或代词是不定式的地点,工具等时,不定式后面应有必要的介词。
B
5. 作状语, 表示目的, 原因, 结果或条件。
e.g.:
I came here to see you
We were very excited to find nobody there.
He hurried to the school to find nobody there.
To look at him, you would like him.
目的
原因
结果
条件
6. 作表语
e.g.: My job is to help the patient.
注意：
主、表都是不定式, 前者为条件, 后者为目的或结果。
To learn a language is to use it.
My chief purpose is _______ the difficulties of the matter.
A. pointing out B. to be pointed
C. pointed D. to point out
本句的意思是: 我的主要目的是指出问题的难处。考查动词不定式做表语的情况。Point out 是“指出”的意思。

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。
e.g:
I saw him go out.
不定式的时态和语态
2. 如果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。
e.g:
I am very glad to be working with you.
3. 如果不定式的动作发生在谓语动词之前, 就要用完成时。
e.g:
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, 不定式一般要用被动形式。
e.g:

(2003年上海卷43小题) An?army?spokesman
stressed?that?all?the?soldiers?had?been?ordered?
________?clear?warnings?before?firing?any shots.
A.?to?issue B.?being?issued
C.?to?have?issued D.?to?be?issued
题意：军方发言人强调说：所有的士兵都接
到命令，在开枪射击之前要发出鸣枪警告。
本题考查的是 order?to?do?sth的不定式作
宾语的用法。句子本身较长，要会分析出
句子的大致成分及语法关系，才能正确做出
判断。正确答案为B。
B
2. (2003年北京卷21小题) The?teacher?asked?us
________?so?much?noise?. A.?don’t?make B.?not?make
C.?not?making D.?not?to?make
题意：老师让我们不要弄出太大噪音。 本题考查不定式用法，在动词ask后面不定式
作复合宾语。其否定形式是not?to?do。常见的
这类动词还有tell?,?order等。选D。
D
3. (2002年全国卷32小题)?Having?a?trip?abroad?
is?certainly?good?for?the?old?couple,?but?it?
remains?________?whether?they?will?enjoy?it. A.?to?see B.?to?be?seen C.?seeing D.?seen 题意：出国旅游对于老人们来说当然很好，但他们是否喜欢这样的活动还有待观察。 句子中it是形式主语，whether引导的句子是真正的主语，remains后应是表语，不定式一般表示将来，根据句意，实际上“whether…”是有待于旁人看，所以应选不定式的被动语态作表语。选B。
B
4. (1999年全国高考题) The?purpose?of?new?
technologies?is?to?make?life?easier, ?________?
it?more?difficult. A.?not?make B.?not?to?make
C.?not?making D.?do?not?make 题意：新技术的目的是使生活更容易，而不是让它更困难。本题考查两个并列的不定式短语构成表语从句的用法。既然是并列的句子，其构成形式应一致，都 to?make?sth?…，但从but又可看出后句有意义上的转折，是否定意义。选B。

Writing -3. An example
Humans change the environment in many
ways and the most serious environmental
problems are air pollution and water pollution.
With the development of industry and
agriculture, the air and water have been
seriously polluted, which is doing harm to
us human beings. And many kinds of wild
animals are dying out. So we must get a clear
understanding of the dangerous situation we
are in and take some measures. For example, it is
important to deal with the rubbish in cities. Rubbish must be treated properly, or it may pollute the air and water. And when people breathe polluted air or drink polluted water, they may get ill. So some rubbish should be sorted and sent to different factories. Rubbish, such as old newspapers and glass, should be recycled; some harmful rubbish should be sent to certain places and buried. At the same time, waste gases must be cleaned before they are
returned to the air; and waster water needs be treated before flowing into rivers.
In a word, it is a duty of everybody to solve the problem and we should put into our hearts how important it is to protect the environment.
