动词的过去分词除了构成完成时和被动语态外,还在句子中起定语、表语、状语、宾语补足语的作用。本单元主要讲定语、表语。过去分词作定语、表语表示动词与被修饰词之间是被动关系或被修饰词处于某种状态。上述例子中named作定语,表被动;而lost表示主语所处的状态。
注意现在分词与过去分词的区别:
(1)现在分词与被修饰词之间是主动关系,而过去分词是被动关系。
the living things 生物
a book written by LuXun 鲁迅写的一本书
(2)现在分词表示一个动作正在进行,而过去分词表示动作已经发生。
a developing country 发展中国家
a developed country 发达国家
(3)现在分词说明被修饰词的特点、性质而过去分词表示被修饰词处于某种状态、心理。
