课件23张PPT。Module 4Grammar不定式属于非限定动词。它除了不能作谓语外，在句中可以充当任何成分，可以作主语、表语、宾语、补语、定语和状语。
不定式的时态有：一般式、进行式、完成式、和完成进行式。当不定式的逻辑主语是不定式动作的承受者时，不定式就要用被动形式。Infinitive不定式一般式所表示的动作通常与谓语所表示的动作或状态同时（或几乎同时）发生，或在它之后发生。
主动：to do I’m glad to meet you.
She invited me to attend the meeting.
The boy is old enough to go to school.被动：to be doneThere was nothing to be done.
I’d like to be told what’s going on.
Nothing is allowed to be taken out of the reading room.不定式进行式表示动作正在进行，与谓语动词表示的动作同时发生。
主动：to be doingTo be cycling in a sandstorm is frightening.
They pretended to be working hard when their boss passed them.不定式完成式所表示的动作在谓语动作所表示的动作之前发生。

我不能不钦佩她的勇气。

她只好做这事了。
