语法点拨
动词不定式
不定式由“to+动词原形”构成，其否定形式是“not to do“，不定式可以带宾语或状语构成不定式短语，没有人称和数的变化，但有时态和语态的变化。
不定式可作主语、宾语、状语、表语和定语，但不能单独作谓语。不定式的逻辑主语有时用“for+名词或代词宾格”构成。
1．不定式的用法：
(1)作主语
不定式短语作主语时，往往放在谓语之后，用It作形式主语。例如：
To see is to believe．眼见为实。
It is right to give up smoking. 戒烟是对的。
(2)作宾语
不定式短语作宾语时，如果还带有宾语补足语，往往把不定式宾语放在宾语补足语之后，而用it作形式宾语。例如：
He wanted to go．他想走。
I find it interesting to work with him．
我发现和他一起工作有趣。
(3)作宾语补足语。例如：
He asked me to do the work with him．
他叫我跟他一起做这个工作。
注意：在feel，hear，listen to，look at，notice，observe，see，watch，have，1et，make等词后的补足语中，不定式不带to。但是这些句中如果变成被动结构时，就必须带to。例：
I often hear him sing the song．He is often heard to sing the song·
我常听到他唱这首歌。他经常被听到唱这首歌。
注意：不定式动词在介词but，except，besides后面时，如果这些介词之前有行为动词do的各种形式，那么，这些介词后的不定式不带to，否则要带to。
例如：
She could do nothing but cry．她只会哭了。
What do you like to do besides swim?
除游泳外你还喜欢什么?
I have no choice but to go．我不得不走。
(4)作定语。例如：
I have some books for you to read.
我有几本书供给你读。
注①：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，不定式后面须有相应的介词。例如：
He is looking for a room to live in ．
他在找一个房间住。
There is nothing to worry about．
无什么可担心的。
Please give me a knife to cut with．
请给我把刀子来切东西。
但是，不定式所修饰的名词如果是time，place或way，不定式后面的介词习惯上要省去。例如：
He had no money and no place to live．他没钱没地方住。
注②：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，不定式既可以用主动语态，也可用被动语态，但其意义有所不同。试比较：
A)Have you anything to send?你有什么东西要寄吗?(不定式tosend的动作执行者是you)
B)Have you anything to be sent?你有什么要(我或别人)寄的东西吗?(不定式to be sent的动作执行者是已被省略的me或someone else)
(5)作状语，表示目的、原因、结果或条件。例
I came here to see you．(目的)
We were very excited to hear the news．(原因)
He hurried to the school to find nobody there . (结果)
To look at him，you would like him．(条件)
要是看见他，就总会喜欢他的。
目的状语还可以用in order to或so as to来表示。例如：
In order to pass the exam，he worked very hard．
为了考试及格，他学习很刻苦。
We ran all the way so as not to be late．
为了别迟到我们一路上跑来的。
不定式也可以在作表语用的形容词后面作状语。例如：
I am very glad to hear it 听见这事我很高兴。
The question is difficult to answer．这个问题难回答。
“too+形容词或副词+不定式”也作状语。例：
He is too old to do that．
他太老不能做这事了。
另外句子中有enough这个词时，常用不定式作状语。例如：
The room is big enough to hold us．
这间屋子够大能盛得下我们。
(6) 作表语。例如：
My job is to help the patient 我的工作是帮助病人。
(7)作独立成分。例如：
To tell the truth，I don't agree with you．
说实话，我不同意你的观点。
(8)不定式与疑问词who，which，when，where ,how，what等连用，在句中起名词作用，可充当主语表语、宾语等。例：
He didn't know what to say. (宾语)
他不知道说什么。
How to solve the problem is very important （主语）
如何解决这个问题很重要。
My question is when to start．(表语)
我的问题是什么时候开始。
注意：在与why连用时，只用于why或why not开头的简短疑问句中，后面紧跟的动词不定式不带to。例：
Why not have a rest?
(9)不定式在句中用主动式还是被动式，多数情况下是容易判别的，但有时的确比较复杂，请注意以下几点：
A)不定式修饰的名词或代词和不定式逻辑上构成主谓关系时，不定式往往用主动形式。
Have you got a key to unlock the door?
你有开门的钥匙吗?
(A key unlocks the door．)
B)不定式和它前面被修饰的名词或代词构成逻辑上的动宾关系，又和该句主语构成逻辑上的主谓关系时，不定式常用主动形式。
I have got a letter to write．(I write a letter．)
我有封信要写。
He needs a room to live in．(He lives in a room．)
他需要间屋子住。
C)不定式作表语形容词的状语，和句中的主语构成逻辑上的动宾关系时，不定式多用主动形式，这是因为人们往往认为形容词后省去了for one或for people．例如：
He is hard to talk to．很难跟他交谈。
The book is difficult to understand．这本书很难懂。
但如果强调句中的受事者时，亦可用不定式被动句。例如：
The handwriting is very difficult to be read．
这字太难认读了。
The box is to heavy to be lifted．
这箱子太重举不起来。
D)在there be结构中，当说话人考虑的是必须有人去完成某件事时，不定式用主动形式，如果说话人强调的是事情本身必须完成，则用被动形式。
There is a lot of work to do． (Somebody has to do the work．)
There isa lot of work to be done．(The work has to be done．)
请注意下面两个句子的含义是不同的：
There is nothing to do．意为无事可做，感到十分乏味。
There is nothing to be done．意为某东西坏了，无法使之恢复正常。
2．不定式的时态
(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。例如：
I saw him go out．我看见他出去了。
(2)如果谓语表示的动作(情况)发生时，不定式表示的动作正在进行，这时不定式就要用进行式。
例如：
I am very glad to be working with you．很高兴和你一起工作。
(3)如果不定式的动作发生在谓语动词之前，要用完成式。例如：
I'm sorry to have kept you waiting．对不起让你久等了。
3．不定式的语态
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。例如：
He asked to be sent to work in the countryside．
他要求被派往农村工作。
