众所周知,动词不定式的基本形式是“to+动词原形”,它具有名词、形容词、副词的特征,因此,在句子里可用作主语、宾语、宾语补足语、定语、状语或表语。但在某些结构中,不定式又往往不带to。现将有关不定式不带to的几种情况综述如下,供同学们学习时参考。

一、用在感觉动词see,watch,notice,look at,hear,listen to,feel等后,作为宾语补足语的动词不定式不带to。如:

I saw her go to school by bike.

我看到她骑自行车上学。

We offten hear her sing in the morning.

我们常听到她在早晨唱歌。

二、用在使役动词make,let,have等后,作为宾语补足语的动词不定式不带to。如:

The teacher has the students write a composition every week.

老师要学生每星期写一篇作文。

His father let him stay at home alone.

他父亲让他一个人呆在家里。

注意:感觉动词see,watch,notice,look at,hear,listen to,feel和使役动词make,let,have等用于被动语态时,动词不定式为主语补足语则要带to。如:

They were made to leave their own hometown.

他们被迫离开家乡。

三、用在had better,had best,would rather(宁愿)等结构后,动词不定式不带to。如:

You'd better go and look for her.

你最好去找找她。

We would rather go to see a film.

我们宁愿去看电影。

四、两个或两个以上句法功能相同的动词不定式并列使用时,通常只是第一个动词不定式带to,后面的动词不定式则不带to。如:

We began to read and write.

我们开始读和写。

He decided to go and get some medicine.

他决定去买点药。

五、在“Will you please+动词不定式”一类表示邀请或命令的句型中,动词不定式不带to。如:

Will you please bring me some meat?

请你给我带点肉来好吗?

Will you please help me with my English?

请你帮我学英语好吗?

六、用在由“Why…”或“Why not…”一类表示建议的句型中,动词不定式不带to。如:

Why not go to see a doctor?

=Why won't you go to see a doctor?

为什么不去看医生?

Why waste so much time?

为什么浪费这么多时间?

七、用在助动词will,shall,would,do和情态动词can,may,must,need,dare等后,动词不定式不带to。如:

She can sing in English.

她会用英语唱歌。

Unfair!How dare you say that?

不公平!你怎么敢这么说?

注意:ought to,have to中的to不能少。dare和need用作实义动词时,后面的动词不定式要带to。如:

He doesn't dare to swim in the river.

他不敢在河里游泳。

八、用在动词help后作为宾语补足语的动词不定式既可以带to,也可以不带to。如:

Will you help me(to)repair my bike?

请你帮我修理一下自行车好吗?

He often helps me(to)do my lessons.

他常帮我做功课。

九、用在do anything/nothing/everything but/except一类结构后,动词不定式不带to。如:

Can't you do anything but ask such silly questions?

难道你只会提这些愚蠢的问题吗?

He could do nothing except wait.

他除了等别无办法。
