Unit 1

过去分词作定语
[例句展示] 仔细观察下列句子中的过去分词的用法。 1. The recovered animals will be released soon. 2. We needed much more qualified workers.

3. Paper

cuts used for religious
purposes are often found in temples.

4. He is a teacher loved by his students.
5. The student dressed in white is my

daughter. = The student who is
dressed in white is my daughter.

[自我归纳] 1. 过去分词作定语时,表示的动作在 ________之前发生,已经完成并具 谓语动作

有____ 被动意义(见句1)。此时,作
定语的过去分词一般是由_____ 及物 动

词变来的,因为只有此类动词才有
被动意义。

2. 单个的过去分词作定语一般放在被修 之前(见句1、句2)。 饰的名词 _____ ____________ 作定语要放在被修饰 过去分词短语
的名词后面,作后置定语,表示被

动或完成,其作用相当于一个
________(见句3、句4、句5)。 定语从句

[拓展] 1. 不及物动词的过去分词也可作定语, 一般作前置定语,不表示被动意义, 只强调动作完成。 如:fallen leaves落叶;retired workers退休工人;the risen sun升 起的太阳。

2. 如果被修饰的词是由every / some / any / no + thing / body / one所构成的 复合代词或指示代词those或these等 时,即使是单一的过去分词作定语, 也要放在被修饰词的后面。如:

There is nothing changed here since I
left this town.

3. 过去分词短语有时还可用作非限制 性定语,相当于一个非限制性定语 从句,前后用逗号分开。如:

Some of them, born and brought
up in rural villages, had never seen

a train.

[辨析] 过去分词与动词-ing形式作定语时 的区别: 动词-ing形式作定语时与所修饰的名词之 间是主动关系,表示动作正在进行;而 过去分词作定语时,则表示被动或完成 意义。如: Mr Smith, tired of the boring speech, started to read a novel. The prize of the game show is $30,000 and an all expenses paid vacation to China.

过去分词作表语
[例句展示] 仔细观察下列句子中的过去 分词的用法。 1. The street is lined with small shops. 2. Tom was astonished to see his father. [自我归纳] 过去分词作表语时,与谓语动词构成 ____结构,表示主语的性质、特征和 系表 状态 ____。

[辨析]

1. 过去分词作表语时与被动语态的区别:
过去分词作表语,主要表示主语的状 态和特征,而被动语态则表示动作。 如: The cup was broken by my little sister yesterday. The library is now closed.

2. 过去分词作表语与动词-ing形式作表

语的区别:过去分词作表语表示被
动或完成,动词-ing形式作表语表示

主动或进行。如:
She was embarrassed because she

didn’t know the answer.
Today’s meeting was boring.

3. 有些动词如interest, worry, surprise,
frighten等通常用其过去分词形式

来说明人的情况,用动词-ing形式
