5、动词不定式的否定式：动词不定式的否定式是由not + 动词不定式构成，如：It's wrong of you not to attend the meeting.
6、动词不定式的时态形式所表示的时间关系：（1）一般式：动词不定式一般式所表示的动作是和谓语动词所表示的动作同时发生，但在多数情况下，是在谓语动词所表示的动作之后发生，如：We decided to plant more trees this spring.（其后），They often watch us play table tennis.（同时）；（2）完成式：动词不定式完成式所表示的动作发生在谓语动词所表示的动作之前，如：I am sorryto have kept you waiting.（3）进行式：动词不定式进行式所表示的动作正在进行中，而且与谓语动词所表示的动作同时发生，如：She happened to be writing a letter in the room when I came in.
7、动词不定式的被动语态用法：如果动词不定式的逻辑主语为这个不定式所表示的动作的承受者时，不定式一般就用被动语态形式，如：What is to be done next hasn't been decided yet.
