最后，顺便谈谈什么情况下，不定式动词中的“to”要省略。

一、和“make, let”, 及感官动词“see, hear, watch”连用的句型中，“to”必须省略。例如：

(12) Don't make her cry.

(13) I won't let you go now.

(14) We saw a man jump into the lake.

(15) Have you heard me call you ?

(16) Let us go to watch him play the game.

二、在“had better, would rather”后面的不定式动词中的 “to”要省略。例如：

(17) You had better do the work now.

(18) It is late now. I would rather go tomorrow.

要注意的是，在被动语态中“to”这符号可能要重现。例如：

(19) Noone can make him understand the real problem. → He cannot be made to understand the real problem.

(20) We heard them speak English.→They were heard to speak English.
