动词-ed形式作定语
自主探究
阅读下列句子,注意黑体部分的意思及用法。
1.In 1988 Winton's wife found a forgotten journal at home.
2.She always wears faded blue jeans.
3.He is fond of the food cooked by his mother.
4.This is the house built last year.
我的发现 动词-ed形式作定语的两种位置
（1）前置
单个的动词-ed形式作定语，通常放在被修饰的名词______（如例句1、2）。
之前
（2）后置
动词-ed形式的短语作定语，通常放在被修饰的名词______（如例句3、4）。
之后
探究点1 动词-ed形式作定语的意义
1.及物动词的-ed形式通常表示被动和完成。如例1中的a forgotten journal=a journal that has been forgotten。
2.不及物动词的-ed形式通常表示主动和完成。如例2中的faded blue jeans=blue jeans that have faded。
3.某些带有持续意义的及物动词，如honour、love、respect、speak等，其动词-ed形式往往只有被动意义。
What is the language spoken（=that is spoken） in Australia
注意：有些动词-ed形式作前置定语时，既不表示被动，也不表示完成，因为它们已经形容词化，这类词有两个特点：
（1）词汇意义无改变
a retired teacher一位退休教师
a fallen tree一棵倒下的树
（2）词汇意义有改变
a used car二手轿车
a given time指定的时间
探究点2 动词不定式、动词-ing形式和动词-ed形式作定语时的区别
动词不定式作定语通常放在所修饰词之后，表示将来的动作。动词不定式与其所修饰的词之间往往是动宾关系，若该动词不定式是不及物动词，其后要加必要的介词。
作定语的及物动词的分词形式有：动词-ing形式、“being+done”、动词-ed形式。当被修饰的名词与分词之间为主动关系时，用动词-ing形式；当被修饰的名词与分词之间为被动关系且表示正在进行时，用“being+done”；当被修饰的名词与分词之间为被动关系且表示完成时，用动词-ed形式。
Suddenly a good idea occurred to her，but she couldn't find any paper to write it on.突然她想到了一个好主意，但是她找不到纸写下来。
There are many serious health problems associated with smoking.有很多严重的、与吸烟有关的健康问题。
Last night，there were millions of people watching the opening ceremony live on TV.昨天晚上，有几百万人观看开幕式的电视直播。
