礼士蟋蟀进化:什么情况能在不定式中省略TO

来源:百度文库 编辑:高校问答 时间:2024/05/08 17:06:42
请详细叙述各种情况,感谢!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

1)有些动词后的不定式可省“to”

a)祈使动词:make,let,have
The boss made Tom’s father(to)work all day.
b)感官动词:hear,see,notice
I saw him(to)goin to the class-room just now.但用于被动语态时,以上两类句型中省去的“to”都要还原:He was made to do the job at once.

2)不定式的否定需在“to”前加“not”
Mother of ten tells Tom not to play foot ball in the street.

3)作简略回答或为了避免不必要的重复时,不定式常可省略“to”后面的动词,只保留“to”。在动词make,let,see,hear…后可全部省略。

A:Did you go to see the Great Wall?

B:Yes,I went to.

A:Did Mary go there with you?

B:No,her mother didn’t let her.

一边站
