神马品牌网危险废物运输车辆:过去式与过去分词有什么区别？
来源：百度文库 编辑：神马品牌网 时间：2024/05/03 11:46:08
动词有四种形式：原型、过去式、过去分词和现在分词
过去式组成一般过去时
I finished my homework just now.
过去分词组成各种完成时态，构成分词结构以及表示被动语态
I have finished my homework now.
I had finished my homework when my mother came back home.
He came back home after fired by his boss.
He was fired by his boss.
很大的区别.
一般过去式在文章中仅做陈述作用,表达发生了什么事情.
过去分词可以组成完成时,表达已经发生的事;可以做为分词定语修饰名词(作用和形容词一样);也可以做为楼上说的被动语态,表示"被"怎么怎么了.
