非谓语动词中的过去分词的词性相当于形容词和副词,所以其用法（即主要指在句子中可以充当的成分）就相当于形容词和副词在句中充当的成分.常见的成分一般有：定语、表语、补语、状语
例如：
定语
(fallen) leaves
a present (given by my parents)英语中短语作定语要后置,叫后置定语
表语
I'm (interested) in this book.
补语
I have never heard the song (sung) in English.
I had my hair (cut) last week.
状语（过去分词短语作状语）
(Seen from the top of the hill), the city looks more beautiful to us.
(Caught in a heavy rain), he was all wet.
