[归纳用法]
一、过去分词(短语)作定语的两种位置
1．前置
单个的过去分词作定语，通常放在被修饰的名词之前。
The plluted water was t blame fr the spread f the disease.
被污染的水造成了这次疾病的传播。
2．后置
过去分词短语作定语时，通常放在被修饰的名词之后。
These trucks carry gds imprted frm freign cuntries.
这些卡车运送从国外进口的货物。
二、过去分词作定语的意义
1．及物动词的过去分词通常在语态上表示被动；在时间上表示动作已发生或完成。有时只表示被动。如例句1中的a frgtten jurnal＝a jurnal that had been frgtten。
2．不及物动词的过去分词只表示动作的完成，不表示被动意义。如例句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hnur，lve，respect，speak等，其过去分词往往只有被动意义。
What is the language spken(＝that is spken) in Australia?
[名师点津]
不少位于名词前酷似过去分词的词，实则是形容词。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规定的时间
三、不定式、现在分词和过去分词作定语时的区别
不定式作定语通常放在所修饰词之后，表示将来的动作。不定式与其所修饰的词之间往往是动宾关系，若该不定式是不及物动词，其后应有必要的介词。
作定语的及物动词的分词形式有：现在分词、“being＋过去分词”、过去分词。当被修饰的名词与分词之间为主动关系时，用现在分词；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＋过去分词”；当被修饰的名词与分词之间为被动关系且表完成时，用过去分词。
