Ⅱ.Grammar:
动词-ed形式作定语
动词-ed形式作表语
动词-ed形式作宾语补足语
一、动词-ed形式作定语
过去分词作定语往往与被修饰的词靠得很近，渐渐地成为一个复合词。这种分词叫分词形容词 (the Participle Adjective), 实际上相当于一个单纯的形容词, 除表示“完成”的动作之外, 还表示“被动”的意义。如：
spoken English (英语口语)；
iced beer (冰冻啤酒)；
cooked food (熟食);
fried chips (炸土豆条);
但要注意不及物动词的过去分词常表示“完成”的动作, 而不表示“被动”的意义。如: boiled water(开水); fallen leaves(落叶) ; the risen sun(升起的太阳)等。
1. 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
    ①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。
② 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。
