Grammar
The Past Participle as the Attribute & Predicative
过去分词的语法功能:
过去分词在句中可以作
1.定语 2.表语 3.宾语补足语 4.状语
一、过去分词作定语
1. 作定语用的过去分词如果是单词,一般放在被修饰词的前面。E.g.:
There are many fallen leaves on the roof (屋顶) .
The broken vase has been thrown outside.
steamed roll
retired workers
escaped prisoners
an unknown hero
the exploited classes
returned students
花卷
一位无名英雄
退休工人
被剥削阶级
逃犯
归国留学生
2. 过去分词短语作定语时,则放在被修饰词的后面。 E.g.:
The play performed by the students was a great success.
The novel written by him has sold out in a few days.
注意:
1. 不及物动词没有“被动语态”,所以, 不及物动词的过去分词没有被动的意义,只表示动作的完成.
E.g.: boiled water (开水)
fallen leaves (落叶)
the risen sun (升起的太阳)
spoken English (英语口语)
iced beer (冰镇啤酒)
fried chips (炸土豆条)
cooked food (熟食)
2. 过去分词作定语时,1) 及物动词的过去分词可改为动词为被动形式的定语从句。 E.g.:
time which is lost
lost time
2)不及物动词的过去分词作定语时,可改为动词为完成式的定语从句。
a returned sailor
A sailor who has returned
二、过去分词作表语
He was pleased at what I said.
She looked very worried.
*表语?
过去分词作表语没有“完成”或“被动”之意,而是表示主语的状态、特点或思想感情等。 E.g.:
过去分词作表语用,相当于形容词,最常见的有;
pleased, surprised, worried, excited, married, delighted, disappointed, interested, discouraged, drunk, tired, amused, astonished, limited, crowded, satisfied, puzzled, hurt, upset, bored, frightened, confused, exhausted, complicated, devoted, embarrassed, distinguished, 等。
过去分词作表语与被动语态的区别。分词作表语表示主语的状态,而被动语态则表示被动的动作。
My glasses are broken. 我的眼镜碎了。
My glasses were broken by my son. 我的眼镜被我儿子摔碎了。
(状态)
(动作)
