an escaped prisoner一名逃犯
1. 单个过去分词作定语, 通常前置

set that were produced last year
去年生产的彩色电视机
(2)a letter written to me by my daughter =a letter
that was written to me by my daughter
一封我女儿写给我的信
2. 过去分词短语作定语通常后置,其作用相当
于定语从句,省去了主语和谓语,如:
常见的这类过去分词有:
disappointed(失望的),moved(感动的),interested(感兴趣的),surprised(感到惊讶的) ,shocked(震惊的,震撼的) ,puzzled(迷惑不解的),frightened(受惊吓的)等。
如:a frightened girl一个受惊吓的女孩。

形容词化。
如: a newly--arrived passengers 刚到的旅客
fallen leaves 落叶
4.不及物动词的过去分词一些不及物动词也有过去分词形式,由于不及物动词不可以直接跟宾语,所以不及物动词的过去分词作定语时只表示动作的完成,而没有被动意义。

The newly- built hotel was burnt in the fire.
新建的宾馆在火灾中被烧掉了。
