The tall man is a returned student高个子的那个人是个归国留学生。2. My parents are both retired teachers 我的父母都是退休教师。 (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。 The excited people rushed into building. 激动的人们冲进大楼。 (=the people who were excited) Lost time can never be found again 虚度的时光, 无法挽回。 (=time which is lost) (2)后置定语 少数单个动词的-ed形式, 如left等, 只能作后置定语。 Everything used should be marked 所有用过的东西应该做好标记。 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。 Is there anything planned for tonight? 今晚有什么活动吗? (=that has been planned for tonight)3. We drank some boiled water (=which had boiled )and went on with our work. 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。1）Most of the artists to the party were from South Africa. (MET 90) A.invited B. to invite C.being invited D. had been invited 2）The first text books for teaching English as a foreign language came out in the 16th century. (NMET 94) A. having written B. to be written C. being written D. written3) The Olympic games, in 776 BC, didnt include women players until 1912. A. first playing B. to be first played C. first played D. to be first playing4) Prices of daily foods through a computer can be lower than prices in stores.

(2003 北京春) A. tired, boring B. tiring, bored C. tired, bored D. tiring, boring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 作表语的-ed形式可被much, very, quite等所修饰。 I was very pleased at the news听了这消息我很高兴。1）Cleaning women in big cities usually get _ by the hour. (NMET98) A. pay B. paying C. paid D. to pay2) As we joined the big crowd I got _ from my friends.

(2004 上海) A. seat B. seating C. seated D. to be seating 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入。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。1. I must get my bike repaired我必须请人修理自行车。(宾语补足语)2. The girl was found beaten black and blue人们发现那女孩被打得青一块紫一块。 (主语补足语) (1)动词-ed形式可作表示感觉和心理状态的动词的宾语补足语,这类动词包括see, hear, watch, notice, feel, find, think, suppose, consider等。We thought the game lost我们认为球赛输了。1) Good morning.
