新概念英语第二册语法总结：非谓语动词之分词

1．分词的性质：
具有形容词性质，可以在句中担任表语、定语、宾补、状语，现在分词表示主动，且动作在进行：过去分词表示被动，或动作已完成。

2．分词的形式：
例：             write (vt)                                            rise (vi)
                  主动语态           被动语态                         主动         过去分词
时态
现在时        writing               being written                 rising         risen
完成时        having written    having been written        having risen    

3．用法：

（1）定语    分词置于被修饰名词前
                 分词短语于置于被修饰名词后
      a sleeping baby = a baby who is sleeping
      a running dog = a dog which is running
      a broken glass = a glass which is broken
      a beaten team = a team which is beaten（beaten 是被打败的意思）
     This is the problem discussed at the last meeting.
     The problem being discussed is very important.

（2）表语：
      The book is interesting.
      He is interested in the book.
      The news is exciting.
      He feels excited.

（3）宾语补足语：
     When I woke up, I found my mother sitting beside me.
     I'd like to have this package weighed.
掌握精髓：动词不定式作宾语表示动作的全过程，而现在分词作宾补表示动作正在进行；过去分词表示被动概念。

（4）状语：（以下例句值得一背！）
① If you turn to the left, you'll find the station.
→ Turning to the left, you'll find the station.
② As I didn't receive her letter, I called her up by telephone.

④ When she was asked it she had any bad habit, she answered that she was a heavy smoker.
