Review of past participles
1 过去分词作定语
(1)过去分词作定语时,相当于形容词,其逻辑主语就是它所修饰的名词。分词所表示的动作与其所修饰的名词构成被动关系。单个的过去分词作定语时,常置于其所修饰的名词前;而过去分词短语作定语时,常置于其所修饰的名词后。
过去分词及过去分词短语作定语一般可转换为一个定语从句。
We must adapt our thinking to the changed conditions.=We must adapt our thinking to the conditions that changed.
我们必须调整思路来适应改变了的情况。
1 过去分词作定语
过去分词作定语的几个注意点:
①过去分词修饰something,everything,anything,nothing, somebody nobody 等不定代词以及指示代词 those 等时,要放在这些词的后面。
.He is one of those invited.
他是那些被邀请的人之一。
② 单个的过去分词有时置于名词后作定语,表示强调。"
.The information gained is very precise.
获取的信息很准确。
③ 有些过去分词作前置定语与作后置定语时意思不同。in the given time 在既定的时间内
with the words given 用所给的单词
④ 及物动词的过去分词除表示“完成”的动作之外,还表示“被动’的意义。如:fried chips(炸土豆条)。
不及物动词的过去分词常表示“完成”的动作,而不表示“被动”意义。如:boiled water(开水)等。
Exercise

The concert________(give) by their friends was a success.
written
given
过去分词作表语
(1)过去分词作表语时,总是在连系动词如be,appear,seem, look,remain,feel,get等之后,构成系表结构,表示主语的状态或状况,主语多为人。此时过去分词大多已变成了形容词。
The city is surrounded on three sides by mountains.
这座城市三面环山。
We are all interested in what has been performed.
我们都对表演的节目很感兴趣。
过去分词作表语
(2)过去分词作表语与被动语态的区别:过去分词作表语表示主语所处的状态,而被动语态则表示一个被动的动作。
This lake is badly polluted.
这个湖受到了严重污染。(系表结构,表示状态)
This lake is badly polluted by fossil fuel.
这个湖被化石燃料严重污染了。(被动结构,表示动作)

过去分词作状语
过去分词作状语,修饰谓语动词,进一步说明谓语动词的动作和状态,其逻辑主语通常就是句子的主语,且主语是过去分词动作的承受者。过去分词作状语时,可单独使用,也可以在其前面加上适当的连词,可表示时间、原因、条件、伴随、方式等。
过去分词作状语
(1)过去分词(短语)作状语的句法功能和位置
过去分词(短语)表示被动,表示动作已经完成,其逻辑主语则为句子的主语。过去分词作状语时,可单独使用,也可以在其前面加上适当的连词,可表示时间、条件、原因、让步、方式、伴随等。

假如仅靠你的想象去写,报告是不会令人信服的。
过去分词作状语
(4)过去分词(短语)的独立结构
过去分词(短语)作状语时,其逻辑主语通常是句子的主语,否则,过去分词(短语)前应加上自己的主语,这种带有自身主语的过去分词(短语)被称为过去分词(短语)的独立结构。过去分词(短语)的独立结构通常在句中作状语,可表示时间、原因、条件等。
