The -ed form used as attributives
-ed分词既可以作前置定语, 也可以作后置定语。
1. 单个的过去分词作定语
1) 作前置定语: 这时过去分词的形容词意义强于动词意义。
Grammar I: The -ed form
a. 及物动词的过去分词具有被动和完成意义。 如:
______________一个破损的杯子
__________________一名伤员
b. 不及物动词的过去分词具有主动和完成意义。
_________________一位成年妇女
_________________一名逃犯
a broken cup
a wounded soldier
a grown woman
an escaped prisoner
2) 作后置定语,通常是及物动词的过去分词,这时过去分词意义强于形容词意义。个别单个的过去分词作前置定语或后置定语时, 表达的含义不同。如:
前置定语 后置定语
a concerned look
关切的神色 the authorities concerned
有关当局
a wanted person
被通缉的人 jobs wanted
需要的工作
in a given condition 在一定条件下 a present given by the student 学生送的礼物
a used car
一辆旧车 a car used
一辆用过的车
2. 过去分词短语作定语通常后置,其作用相当于定语从句。如:
the color TV set produced last year =the color TV set _________________ last year 去年生产的彩色电视机
a letter written to me by my daughter =a letter ______________ to me by my daughter 一封我女儿写给我的信
that were produced
that was written
3. 要注意过去分词做定语时动作发生的时间:
1) 发生在谓语动词的动作之前。如:
Is this the book written (that was written) by Henry James
这是亨利·詹姆斯写的书吗
2) 表示与句中谓语动词相应的经常性的动作。如:
He was then a professor respected
__________________ by all the teachers and students of the college. 当时他是一个受这所大学里全体师生尊敬的教授。
(that was respected)
