不定式具有动词的一些特征，有时态和语态的变化。

1. 作主语，如：To see is to believe.眼见为实。

2. 作表语，如：The important thing is to save lives.救人要紧。

高中英语复习讲义动词不定式知识点总结动词不定式是一种非谓语动词形式，其结构为“ to do ”，其中to不是介词，而是动词不定式的符号，称为小品词，动词不定式没有人称和数的变化。

但有时态和语态的变化。

动词不定式和其后面的名词等构成不定式短语，在句子中可以用作主语、表语、宾语、定语、状语、补足语、独立成分或与疑问词等连用。

|不定式时态和语态•Theypretended not to see us.(不定式的一般式表示与谓语动词动作几乎同时发生或者发生在谓语动词动作之后.)•He pretendedto be sleeping.(不定式的进行式表示在谓语动词动作发生的同时,不定式的动作也正在进行)•She pretendedto have known it before.(完成式表示不定式动作发生在谓语动作之前)•We’re happy to have been working with you.(完成进行式表示谓语动作发生之前,不定式的动作一直在进行而且可能之后也继续)01不定式做主语例如：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。

1）单个不定式作主语时,谓语动词用单数2）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，而把真正的主语则为动词不定式（短语）放在句子的后部。

例如上面的句子可以表示为：To learn English well is not easy.= It is not easy to learn English well.To use English every day is important for students. = It is important for students to use English every day.02不定式作宾语( vt. + to do )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, learn, like, hate, love, ask , decide, expect, want, hope, wish, offer, fail, plan, learn, pretend, refuse, manage, help, agree, promise, prefer, mean 等等例如：1）I want to tell you a story. 我想给你讲个故事。

高中英语非谓语动词to do(三)

The room was quite dark inside, so he made some candles to give light.（candles做了to give light的动作，是不定式的逻辑主语）注意：1）如果不定式所修饰的名词是time, place或way,不定式后面习惯上要省略介词。

He had no money and no place to live.2）不定式所修饰的名词或代词是不定式动作的承受者时，不定式既可用主动语态，又可用被动语态，但含义不同。

如果修饰名词的不定式的动作是主语做的, 不定式用主动语态。

试比较：•Have you anything to send?•Have you anything to be sent?3）不定式作定语多表示将来，而动词-ing形式表示正在进行或用途，过去分词则表示已经完成和被动。

a problem to be discussed tomorrow 明天要讨论的问题a problem being discussed now 现在正讨论的问题a problem discussed for thousands of years 已讨论多年的问题6．作状语A. 作修饰动词的目的状语They ran over to welcome the students.注意：不定式表示目的时前面可以加in order 或so as已示强调。

B. 作修饰动词的结果状语1）不定式作结果状语常表示一种事先没有预料到的情况或结果，放在被修饰动词的后面。

What have I said to make you so angry?2）有时为了进一步加强意料不到的语气，在表示结果的不定式前还可加only。

I went to see him only to find him out.7.动词不定式常用句型：(1) It takes / took / will take sb. some time / money to do sth.某人花/花了/将花多长时间/多少钱做某事. 例句：It took me years of hard work to speak good English.(2) It is + adj +for/of sb to do sth。
