考点聚焦
非谓语动词是英语中的一个重要语法。非谓语动词一般叫做非限定性动词，它是动词的非谓语形式。主要包括三个类型:(1)不定式(2)动名词(3)分词。分词又分为现在分词和过去分词。
热点预测:现在分词和过去分词的逻辑主语问题，非谓语动词的被动语态问题，还有非谓语动词做主语的问题。

1.动词不定式一般式表示的动作可能与谓语动词的动作同时发生，也可能在之后发生。例如:I saw the young man enter the house.(同时发生)
I hope to go there next time.(之后发生)
2.动词不定式完成式表示的动作在谓语动词之前发生。例如:I`m sorry to have broken your glasses.
动词不定式进行式表示的动作与谓语动词同时发生。例如:When he came in,I happened to be reading at the table.

4.动词不定式的被动式有两种形式:to be done表示将要被做，to have been done表示已被做。例如:The new cinema to be put up next year will be very large.
The cinema is said to have been built last year.

困了。。

突然发现需要码的很多很多诶~

5.在表示情绪的动词，如like,love,hate等后，用动名词做宾语表示一般倾向，用动词不定式表示特定某事;但在would/should like/love,prefer后要用动词不定式。例如:I hate eating the same food every day.
Would you like to watch TV in the evening?

6.在动词need,want,require后用动名词表示被动含义，相当于动词不定式的被动式;而用动词不定式的主动式则表示主动含义。例如:The house needs cleaning.=The house needs to be cleaned.
He needs to clean the house first.
7.在介词后一般用动名词做宾语，但在少数介词，如but,except后用动词不定式做宾语，但要注意to的省略:如but前有do则省去to。例如:I have done nothing but help him with his luggage.
I have no choice but to wait for him at the bus stop.
