as
Attribute &. Predicative Translate the following phrases, and try to find out what the items relate to.一片碎玻璃
开水
一枚用过的邮票
一箱埋起来的硬币
穿破的鞋子
一台损坏了的计算机
结论:以上的短语都带有过去分词,这些过去分词都是充当定语,而且我们都可以用过去分词作表语的从句来改写以上短语。a broken piece of glassboiled watera used stampa buried box of coinsa damaged computerworn—out shoesGrammar一、过去分词作定语
1、单个的过去分词作定语时一般兼有被动和完成的意义,常作前置定语。
eg:a lost animal 一只迷路的动物
a used stamp 一枚用过的邮票
an injured finger 一个受伤的手指
a broken coin 一枚破损的硬币
a lighted candle 一支点燃的蜡烛
注意:过去分词作定语时,有时只有被动意义。
e.g.:spoken English 英语口语
written exercises 书面练习
少数表示位移或状态改变的不及物动词的过去分词只有完成的意义
fallen leaves 落叶
the risen sun 升起来的太阳
the advanced countries 发达国家
drunken man 一个醉鬼
a returned student 一名留学生
a retired teacher 一名退休教师
an escaped prisoner 一名逃跑的囚犯
by-gone days 过去的岁月
2、过去分词短语作后置定语,表示被动和/或完成意义。
e.g.:How I regretted the hours wasted in the woods!
I like wearing clothes made of this kind of cloth.
The books written by Lu Xun are popular.
We’11 go to visit the bridge built hundreds of years ago.
注意:如果被修饰词是由every/ some/ any/ no +thing/ body/ one所构成的复合代词或指示代词those/ these等时,即使是单个过去分词做定语也要放在被修饰词之后。
Eg. There is nothing changed since I left here.
从我离开,这里就没有改变过。 为了加强语气,或被修饰名词前有形容词最高级或类似修饰语,有些单个过去分词也可以置于被修饰词之后。如:left, given, concerned (with…), used, spoken/ written
Eg. In many countries, words spoken are different from words written.

This is the only chance left.3、过去分词、不定式(被动式)、现在分词(被动式)作定语的区别:
e.g.:
The house built last year is our new library.
The house being built now will be our new library.
The house to be built next year will be our new library.(表将要进行的被动 )(表正在进行的被动)(表完成或被动)4、过去分词作定语,相当于一个定语从句,它是由省去主语和助动词而形成的。
e.g.:We all like the lecture given by him.
=We all like the lecture that is given by him.
Some of them, born and brought up in rural area, had never seen a train.
= Some of them, who were born and brought up in rural area, had nevefr seen a train. Complete the table with phrases that have the same meaning.Past Participle Past Participle

______________________ there?
which is being built注:本句中的现在分词被动式作定语,表示被动的动作正在进行。二、过去分词作表语
1、过去分词作表语,表示主语的特点或所处的状态,多用表示心理情感类的词,如interested, delighted, surprised等。其前的系动词有包括be在内的多种形式。
e.g.:Everyone present is very inspired at his speech.
You seem frightened.2、过去分词作表语,构成的系表结构与被动语态的区别:
过去分词作表语,强调主语的特点或所处的状态;而被动语态中,主语是动词所表示动作的承受者。
e.g.:This shop is now closed.
这家商店现在已经关门了。(状态)
This shop is closed at 6 pm everyday.
