过去分词作表语和定语概念引入今天我们要学习过去分词作表语和定语的用法。
先看下面这些句子:1. But he became inspired when he thought about helping ordinary people exposed to cholera.(inspired过去分词作表语;exposed过去分词作定语)2. So many thousands of terrified people died every time there was an outbreak.(terrified过去分词作定语)3. He became interested in two theories that possibly explained how cholera killed people.(interested 过去分词作表语)4. From the stomach the disease quickly attacked the body and soon the affected person died.(affected过去分词作定语)5. He was determined to find out why. (determined过去分词作表语)6. He found that it came from the river polluted by the dirty water from London.(polluted过去分词作定语)上面句子中的黑体词都是过去分词,句1(inspired)、句3、句5中的三个词跟在系动词became、was后作表语;而句1(exposed)、句2、句4、句6中的四个词放在名词前或后修饰名词,作定语。
那么过去分词是什么?有什么作用?我们将在本单元和下两个单元中与同学们一起学习。
语法讲解英语中动词如果不作谓语时叫非谓语动词。
非谓语动词分为:不定式(to do)、动词-ing 形式(doing)和过去分词(done)。
§语法归纳过去分词作表语和定语1.过去分词作定语过去分词作定语与所修饰词之间存在两种意义关系:一是及物动词表被动意义(或已完成的被动动作);二是不及物动词表示完成意义。
an organized trip有组织的旅行(被动)The question discussed was very important.被讨论的问题非常重要。
(即表被动又表完成)boiled water开水(完成)fallen leaves落叶(完成)(1)单个的过去分词作定语一般放在被修饰的名词之前,有时也放在被修饰的名词之后。
My friend is a returned student.我的朋友是个归国的留学生。
The excited people rushed into the hall.激动的人们冲进大厅。
There is no time left.没有多少时间了。
(2)过去分词短语作定语要放在被修饰的名词后面,作后置定语,作用相当于一个定语从句。
The student dressed in white is my daughter.=The student who is dressed in white is my daughter.穿白色衣服的学生是我的女儿。
Is there anything planned for tonight?=Is there anything that has been planned for tonight?今晚安排了什么活动没有?The book, written in 1957, tells the struggle of the miners.=The book, which was written in 1957, tells the struggle of the miners.这本书是1957年写的,讲的是关于矿工斗争的故事。
2.过去分词作表语过去分词作表语,表示主语所处的状态(用作表语的过去分词大多已形容词化)。
