1、在使役动词后面:

使役动词是指让别人做事情的动词。主要有have、get、make、let、leave、help等。

如:

I would have Tom do this job.

You shouldn’t have let him leave without a word.

2、在感官动词后面

如:

I saw Tom fall off his bicycle yesterday afternoon.

3、当两个或以上的不定式连在一起的时候,后面的to可以省略。但是当表示几个不定时之间比较或强调的时候则不能省略to。

如:

I am going to see the president and ask him to solve this problem.

Tom is here to make friends not to make trouble.

4、前有do,后无to

如果前面的主语有do,做表语的不定式省略to。

What I want to do this weekend is see my father.

5、except/but后面省略to

Tom had no choice but do his homework again.

I can do every thing except washing.

6、help后面可以省略to

help后面的to可以省略也可以保留。

Tom helped me do my homework.

注意使役动词在主动格式时可以省略to,但是在被动的时候就需要加上to。

Tom made his mother repeat the story.

Tom’s mother was made to repeat the story.
