需要省略to的不定式的情况有:

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。

一些重要的区分:

1) stop doing/to do

stop to do 停止,中断做某事后去做另一件事,stop doing 停止做某事。例如:

They stop to smoke a cigarette. 他们停下来,抽了根烟。

I must stop smoking. 我必须戒烟了。

2)forget doing/to do

forget to do 忘记要去做某事,forget doing 忘记做过某事。例如:

The light in the office is stil on. He forgot to turn it off. 办公室的灯还在亮着,他

忘记关了。(没有做关灯的动作)
