动词-ed形式作定语，表语，宾语补足语和状语
一、动词-ed形式作定语
过去分词作定语往往与被修饰的词靠得很紧,渐渐地成为一个复合词。这种分词叫分词形容词(the Participle Adjective),实际上相当于一个单纯的形容词,除表示“完成”的动作之外,还表示“被动”的意义。如：
spoken English (英语口语)；iced beer (冰冻啤酒)；cooked food (熟食); fried chips (炸土豆条);
但要注意不及物动词的过去分词常表示“完成”的动作,而不表示“被动”意义。如: boiled water(开水); fallen leaves(落叶) ; the risen sun(升起的太阳)等。
(1)前置定语 单个的动词-ed形式,一般放在被修饰的名词的前面,作前置定语。 激动的人们冲进大楼。(=the people who were excited)
．虚度的时光,无法挽回。(=time which is lost)
(2)后置定语 ①少数单个动词的-ed形式,如left等,只能作后置定语。
1. Everything used should be marked．所有用过的东西应该做好标记。
2. Among the invited were some ladies．被邀请的人中,有些是女士。
3. The books left are for my students．剩下的书是给我的学生的。
②动词-ed形式短语作定语时,通常要放在被修饰的名词的后面,在意思上相当于一个定语从句。及物动词的过去分词作定语用来表示被动,可改为带被动语态的定语从句;不及物动词的过去分词(仅限于单个过去分词,且不能后置)则表示完成,可改为带有完成时态的定语从句。
1. Is there anything planned for tonight? 今晚有什么活动吗? (=that has been planned for tonight)
2. The meeting, attended by a lot of people, was a success．这次会议有很多人出席,开得很成功。 (=which was attended by a lot of people) 我们喝了一些开水后就继续工作。 注意:这里的过去分词的逻辑主语应是被修饰的词,改为定语从句时关系代词应与之一致。
二、动词-ed形式作表语 过去分词作表语并无“完成”或“被动”之意，而是表示主语的状态或思想感情等。如： He looked worried after reading the letter．看完信后,他显得很忧虑。
When we heard of it, we were deeply moved．当我们听到这件事时,被深深地感动了。
He seemed quite delighted at the idea．听到这个想法,他似乎很高兴。
常见的作表语的过去分词有:
amused(愉快的)； broken(碎了的)；closed(关闭的)；astonished(吃惊的)；crowded(拥挤的)；experienced(有经验的); delighted(高兴的)；lost(丢失的)；gone(遗失的)；disappointed(失望的)；worried(担忧的)；interested(感兴趣的) tired(疲劳的) pleased(高兴的)；satisfied(满意的)； surprised(吃惊的); married(已婚的)； known(著名的) 等等
三、动词-ed形式作宾语补足语
能用作宾语补足语的过去分词一般都是及物动词,表示被动意义或已完成意义,有时候两者兼而有之。作宾语补足语的过去分词与宾语有逻辑上的动宾关系,即宾语是过去分词动作的对象。
She found the door broken in when she came back．她回来时发现有人破门而人。
My grandfather had his old house rebuilt．我爷爷找人重修了一下他的旧房子。
少数不及物动词的过去分词用作宾补时,强调动作完成后的状态.
They found all the guests gone when they woke up.当他们醒来时,发现所有的客人都走了。
