哪些词语后面跟动词原型
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:

=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:
