动词不定式具有名词、形容词和副词的特征，因此，在句中可以作主语、表语、宾语、宾语补足语、定语和状语。

一、常接不定式作宾语的动词有want，love，learn，agree，decide，hope，refuse等。例如：

I'm learning to skate on real ice. 我正在真正的冰上学滑冰。

[特别提醒]不定式短语作宾语时，如果还带有宾语补足语，通常用it作形式宾语，而把不定式短语放在宾语补足语之后。例如：

He found it very difficult to get to sleep.他发现入睡很困难。

二、动词不定式常用作目的状语。例如：

He came to give us a talk yesterday. 他昨天来给我们作了个报告。

Mrs Brown went to see her doctor. 布朗夫人去看她的医生了。

三、tell，ask，want，order，get，wish，warn，teach，invite等动词后常跟不定式作宾语的补足语，构成tell/ ask……sb to do sth(“告诉/请……某人做某事”)结构。例如：

Could you ask him to call me，please? 请你让他给我打个电话，好吗?

[特别提醒]使役动词let，make，have等，感官动词see，hear，feel，watch，notice，look at，listen to等，后常跟不带to的不定式作宾语补足语。例如：

A woman saw it happen when she was walking past. 一位妇女路过时看到(它掉下)了。

We often heard her sing in the next room. 我们经常听到她在隔壁唱歌。

注意：在被动语态句子中，不定式前必须加to.例如：

He was made to do it. 他被迫做这件事。

She was often heard to sing in the next room. 经常听到她在隔壁唱歌。

四、不定式短语作定语要放在被修饰的词语之后。例如：

I have a lot of work to do. 我有许多事情要做。

五、不定式短语作主语时，常用it作形式主语，真正的主语不定式短语放在后面。例如：

It is right to give up smoking. 戒烟是有益的。

六、作表语。例如：

To him，the first important thing was to save lives. 对他来说，最重要的事情就是拯救生命。

His wish is to become a scientist. 他的愿望是当一名科学家。

七、动词不定式用在疑问词how，when，where，what，which等之后，作宾语或宾语补足语。例如：

He taught us how to use a computer. 他教我们如何使用计算机。

I don't know where to go? 我不知道去哪里。
