动词不定式的否定式及被动语态！

动词不定式的否定式由 not/never＋to do 构成，另外还有 in order not to do，so as not to do。

I told him not to do it.

我让他别那样做的。

Father warned me never to drive after drinking.

动词不定式的被动语态

当不定式逻辑上的主语是不定式所表示的动作的承受者时，不定式一般要用被动式。

I'm pleased to have been given this opportunity.

给了我这次机会我很高兴。

连接词＋不定式

连接代词和连接副词及whether后可接不定式，在句中起名词作用，可充当主语、表语和宾语。

I know what to do.(I do what)

我知道要做什么。
