Step 3: 单个的过去分词作定语,常作前置定语。

a used stamp

a painted house

the finished work

fallen leaves

boiled water →及物动词的过去分词具有被动和完成意义.:不及物动词的过去分词仅表动作的完成，无被动意义，

Step 4: 过去分词短语作定语通常后置，其作用相当于定语从句。如:

a very enthusiastic woman called Ms Shen

= a very enthusiastic woman who is called Ms Shen a letter written to me by my daughter

=a letter that was written to me by my daughter the student praised by the teacher = the student who was praised by the teacher 注：1.left 习惯上作后置定语

have little money left

The money left couldn’t cover the price of

the coat.

2.过去分词修饰指示代词those或者不定代词

something, everything, nothing, anything, nobody, anybody, anyone 时，要放在其之后。

3. 过去分词与现在分词的区别：

1). 不及物动词的过去分词表示动作的完成和主动意义，而其现在分词表示正在发生和主动意义。

falling leaves

boiling water

fallen leaves

boiled water

developing countries

the rising sun

developed countries

2).及物动词的过去分词表示动作的完成和被动意义，而现在分词表示正在发生和主动意义

3).某些动词的过去分词作定语表示被修饰的人或物所处的状态时，这些词常没有被动的意思，而是一个形容词，意为“感到…..”。该动词的现在分词作定语，常修饰事物，说明事物本身的性质特征，意为“令人…..的”

the excited children

the puzzled look

surprised expression

the exciting news the puzzling question

a surprising result

4)过去分词与其它非谓语形式作定语的区别：

现在分词doing表示主动，正在进行，其被动语态being done表示正在进行的被动动作。不定式to do表示将要发生的动作，其被动语态to be done表将要发生的被动动作。
