[動詞不定式]省去to 的動詞不定式
1) 情態動詞 ( 除ought 外) 後。
2) 使役動詞 let, have, make後,感官動詞 see, watch, look at, notice , observe, hear, listen to, smell, feel, find 等後。
注意:被動語態中不能省去to.例如:
I saw him dance. 我看見他跳舞。
=He was seen to dance.
The boss made them work the whole night. 老板讓他們整夜乾活。
=They were made to work the whole night.
3) would rather,had better句型後
4) Why… / why no…句型後
5) help 後可帶to,也可不帶to, help sb (to) do sth:
6) but和except後。but前是實義動詞do時,後麪出現的不定式不帶to.
比較:He wants to do nothing but go out. 他衹想出去玩。
He wants to believe anything but to take the medicine. 除了喫這葯,他什麽都信。
7) 由and, or和than連接的兩個不定式,第二個to 可以省去:
8) 通常在discover, imagine, suppose, think等詞後作賓補時,可以省去to be.例如:
He is supposed (to be) nice. 他應該是個好人。
