1．过去分词作定语时的位置
(1)前置定语
一般情况下，单个过去分词作前置定语，即放在所修饰词之前。
The polluted water was to blame for the spread of cholera.
被污染的水造成了霍乱的传播。
The recovered animals will be released soon.
痊愈的动物会很快被释放。

①有些过去分词表示特定含义时，单独作定语也放在所修饰的名词之后，如left(剩余的)，given(所给的)，concerned(有关的)等。
There are few tigers left. It is time for the departments concerned to take measures to protect them from dying out.
剩余的老虎不多了，是相关当局采取措施保护它们免遭灭绝的时候了。
②如果被修饰的词是由every/some/any/no与thing/body/one所构成的复合代词或指示代词those等，单个分词放在被修饰词的后面。
Is there anything unsolved?
还有什么没解决的吗？
(2)后置定语
过去分词短语作定语时往往作后置定语，即放在所修饰词之后，它的作用相当于一个定语从句。
Last Tuesday in a mountainous area, there were a total of 173 sheep killed almost immediately(＝which were killed almost immediately) when lightning struck.
上周二在一个山区，当雷击发生时有173只羊即刻被雷电击死。
