一、定义
二、特点
动词不定式与动词 ing形式、过去分词一样，是动词的非谓语形式。它与动词原形同形，但它的前面一般要带有一个不定式的符号“to”，不定式to后为动词，介词to后为名词、代词或动名词。动词不定式存在不带to的情况。
动词不定式是非谓语动词的一种。非谓语动词是指那些在句中不能单独充当句子谓语的动词形式。动词不定式有及物和不及物之分，有时态和语态的变化。动词不定式除了谓语外可以作其他任何句子成分，包括主语、宾语、表语、状语、定语或宾语补足语。它可以在句子中起名词、形容词和副词的作用。
动词不定式
三、不定式的形式
时　态 主动语态 被动语态
一般式 to＋动词原形 (to do) to be＋过去分词
(to be done)
完成式 to have＋过去分词 (to have done) to have been＋过去分词 (to have been done)
进行式 to be＋现在分词(to be doing) —
完成 进行式 to have been＋现在分词 (to have been doing) —
1. 一般式：不定式的动作与谓语动作同时发生或在谓语动作之后发生。
He seems to know this.
他似乎知道这件事。
2. 进行式：不定式的动作与谓语动作同时发生，并强调动作的持续性或正在进行。
He pretended to be working hard.
= He pretended that he was working hard.
他假装工作很努力。
3. 完成式：不定式的动作发生在谓语动作之前或已经发生。
Scientists claimed to have made a major breakthrough in the fight against cancer in the past three months.
科学家们宣称在过去的三个月里在攻克癌症方面已有重大的突破。
4. 完成进行式：强调不定式的动作从过去某一时刻起一直持续到某一时刻，强调动作的持续性，不强调结果。
The rain was said to have been falling for a week.
据说雨已经下了一周了。
四、不定式的用法
1.作主语
To be a doctor is hard．做医生很难。
To learn English well is not easy．学好英语不容易。
动词不定式(短语)作主语时，为了避免句子的头重脚轻，可以用“it”作形式主语，而把真正的主语——动词不定式(短语)放在句子的后部。
例如上面的句子可以表示为：
It is hard to be a doctor.做医生很难。
It is not easy to learn English well．学好英语不容易。
2.作表语
在形式上，位于系动词后的就是表语。从含义上讲，表语是回答主语“是什么”或“怎么样”的句子成分。
动词不定式(短语)作表语常用于系词be的后面。
His work is to drive a car．他的工作是开车。
My job is to feed animals．我的工作是饲养动物。
Her ideal is to be a doctor．她的理想是当医生。
3.作宾语
动词不定式(短语)可以放在一些动词后面用作宾语，能以动词不定式作宾语的动词有：begin, start, want, forget, remember, show, learn, like, hate, love, ask等。
I want to tell you a story．
我想给你讲个故事。
They begin to work at eight every morning．
他们每天早晨8点开始工作。
【拓展提升】
1.如果and连接两个动词不定式，第二个动词不定式一般省“to”。
He wants to have a swim with us.
他想和我们一起去游泳。
2.若作宾语的动词不定式(短语)很长，可用it作形式宾语。
I find it interesting to learn English with you.
我觉得和你一起学英语很有趣。
He found it hard to catch up with others.
他觉得赶上别人很困难。
4.作宾语补足语
1.不可以省to的不定式作宾语补足语。
tell/ask/want/would like/teach sb. to do sth.
The teacher told us to come earlier tomorrow.
老师要求我们明天早点来。
2．省略to的不定式作宾语补足语。
Let the boy go out now．现在让那个男孩出去。
I saw the students play basketball on the playground yesterday.
昨天我看见学生们在操场打篮球。
5.作后置定语
动词不定式作定语常用来修饰名词或不定代词，放于所修饰的词后，为后置定语。
Who was the first one to arrive 谁是第一个到的？
She has no paper to write on．她没有纸写字。
【拓展提升】
动词不定式(短语)作定语修饰名词时，与其所修饰的名词具有一种动宾关系，如果不定式中的动词为不及物动词时，其后应加上一个含义表达上所需要的介词。
I have no chair to sit on.我没有椅子坐。
6.作状语
动词不定式作状语常用在go, come, hurry等不及物动词后。
He went to see his sister yesterday.他昨天去看妹妹了。
【拓展提升】
不定式作状语，可表示动作的目的、结果、原因、条件和方式。
A．表目的
He goes there to enjoy the fresh air．他去那儿享受新鲜空气。
B．表结果
I went to the classroom, to discover it empty．
我走到教室，结果发现教室是空的。
C．表原因
I’m very glad to hear that Li Lei has been elected secretary of the Party.
听说李蕾被选为书记，我很高兴。
D．表条件
To be heated, liquid will change into gas．如果受热，液体就会变成气体。
E．表方式
He moved his mouth as if to say something.
他动了动嘴唇，好像要说什么事似的。
