1) 情态动词 ( 除ought 外) 后。

2) 使役动词 let, have, make后,感官动词 see, watch, look at, notice , observe, hear, listen to, smell, feel, find 等后。

注意:被动语态中不能省去to.例如:

I saw him dance. 我看见他跳舞。

=He was seen to dance.

The boss made them work the whole night. 老板让他们整夜干活。

=They were made to work the whole night.

3) would rather,had better句型后

4) Why… / why no…句型后

5) help 后可带to,也可不带to, help sb (to) do sth:

6) but和except后。but前是实义动词do时,后面出现的不定式不带to.

比较:He wants to do nothing but go out. 他只想出去玩。

He wants to believe anything but to take the medicine. 除了吃这药,他什么都信。

7) 由and, or和than连接的两个不定式,第二个to 可以省去:

8) 通常在discover, imagine, suppose, think等词后作宾补时,可以省去to be.例如:

He is supposed (to be) nice.他应该是个好人。

典型例题

1) —— I usually go there by train.

---- Why not ___ by boat for a change?

A. to try going B.trying to go C.to try and go D.try going

答案:D. why not 后面接不带to 的不定式,因此选D.

2) Paul doesn’t have to be made ___. He always works hard.

A. learn B. to learn C. learned D. learning

答案:B. make后接不带to 的动词不定式,当其用于被动时,to 不可省略。
