是不是只有情态动词和助动词后面才用动词原形

如题所述

不是的奥,还有如下几种情况加动原!
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 not…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.

情态动词和助动词后面一定用动词原形,但不是只有情态动词和助动词后面才用动词原形,动词不定式结构也是to + 动词原形;有些动词后的不定式作宾语被足语时也用动词原形;还有一些固定用法后也跟动词原形。
如:
1.He can swim . (情态动词后跟动词原形)
他会游泳。

2. Do you go to school by bus ?(助动词后跟动词原形)
你乘公共汽车上学吗?
3. My mother asks me to go home on time.(不定式to后跟动词原形)
我妈妈叫我按时回家。
4. Jim made us laugh .(make sb do sth 固定用法)
吉姆让我们笑了。
5. He will leave here next week .(情态动词后跟动词原形)
他下周要离开这里。
6. Why not go with us ? (固定用法why not do sth )
为什么不和我们一起去?
7. She used to be a teacher .(固定用法used to do sth)
她过去是名老师。

助动词,以及动词不定式to后一般加动词原形。情态动词后即可以加原型,也可加现在完成时,如:I should have quitted my job. 我应该早把工作辞掉的

情态动词后面必须跟动词原形
助动词要看是什么助动词,在助动词do或did后面一般跟动词原形,但是,助动词have或has后面就用过去分词,构成现在完成时.助动词had后面也是跟过去分词,构成过去完成时

3) would rather,had better句型后
4) Why… / why not…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.
