1、分词做表语通常表示主语所具有的特征，如the film we saw yesterday was really moving，再如， they were excited on hearing the news
2、单独一个分词作定语通常放在所修饰的名词前面，如an understanding man， a developing country. 分词短语作定语往往放在所修饰的名词之后，实际上是一个定语从句的省略
3、分词作状语实际上就是一个并列句或状语从句的省略，并对句子稍做改动，如When asked about it , she s锾攒揉敫aid she knew nothing，这句话等同于when she was asked about it , she said she knew nothing
4、使役动词have, make, get, keep, leave等接过去分词作宾语补足语有两种情况：过去分词所表示的动作由他人完成，过去分词所表示的动作由主句中的主语所经历
5、现在分词的完成时（having done)主要用于状语从句，强调分词的动作发生的谓语动作之前。简单的说如果状语的时态是完成时，在省略时，也用分词的完成时
6、现在分词的被动语态（being done）和完成时的被动语态（having been done)，主要用于定语从句和状语从句。如I heard the noise of furn足毂忍珩iture being moved upstairs等同于I heard the noise of furniture that was being moved upstairs
