（二）本章语法
1. 分词的结构
我们所说的分词包括现在分词和过去分词
现在分词结构主要有：doing，being done，having done，having been done
过去分词只有done
2. 分词的用法

（3）分词做宾补
如：I saw him cooking just now.

（4）分词做状语，做状语的分词一般在句首，表示时间，方式，条件和原因，起到时间，方式，条件和原因状语从句的作用；放在句末一般表示伴随着谓语动词的一种情况或结果。
如：Entering the room, I found myself alone.

现在分词一般表示与谓语动词同时发生或先于谓语动词发生的动作。

Hearing the news, she burst into laugh.
现在分词的完成式表示发生在谓语动词之前的动作，
如：Having eaten too much, he nearly couldn’t stand up.
Not having seen the result of the game, he asked the man next to him.
现在分词的被动语态一般表示一个被动的动作正在进行，

现在分词的被动语态完成式一般表示一个被动的动作先于谓语动词已完成，

过去分词只有一种形式，同时表示被动与完成，与现在分词被动完成式相似，但后者更强调完成。
