重点语法
过去分词作定语和宾语补足语
一、过去分词作定语
过去分词是非谓语动词的一种形式，它既保留了动词的某些特征，又具有形容词和副词的特征。
1. 过去分词作定语时的位置
单个过去分词作定语一般置于被修饰的词语之前，过去分词短语作定语时一般置于被修饰的词语之后。
To her the outside world was a totally unknown quantity. 对她来说，外部世界完全是个未知数。
Who were the so-called guests invited to your party last night? 昨晚被邀请参加你的聚会的那些所谓的客人是谁呀？
Things bought through computers are much cheaper. 通过电脑购买的物品要便宜得多。
2. 过去分词作定语时的功能
过去分词作定语时，其功能相当于一个定语从句，因此可以改为相应的定语从句。
The injured workers are now being taken good care of in the hospital. = The workers who were injured are now being taken good care of in the hospital. 受伤的工人现正在医院受到良好的照料。
Polluted air and water are harmful to people's health. = Air and water which have been polluted are harmful to people's health. 被污染的空气和水对人们的健康有害。
