单元语法

过去分词作表语与状语

1 过去分词作表语

（1）过去分词可放在连系动词 be，get，feel，remain，seem，look，become 等之后作表语，表示主语所处的情绪或状态。

Please remain seated；the winner of the prize will be announced soon.请继续坐着，奖品的获得者很快就会宣布。 ［词汇复现］

（2）过去分词作表语与被动语态的区别

“be+ 过去分词”表示状态时，是系表结构，此时分词通常已形容词化；表示动作时，是被动语态，且绝大多数被动结构中的动作执行者由介词 by 引出。

Brian was relaxed when he was sitting on the sofa and watching TV.布赖恩坐在沙发上看电视时感到很放松。

The whole city was destroyed by the terrible disaster.整个城市被可怕的灾难摧毁了。 ［词汇复现］

（3）英语中有很多与感觉有关的使令动词，其现在分词表示主动意义，

即“令人……的”，多用来修饰物；其过去分词表示被动意义，即“感到……的”，多用来修饰人、人的声音或表情等。常用的这类词有：

They were shocked to know that some people died of the unknown

disease. 得知一些人死于这种未知的疾病，他们感到震惊。 ［词汇复现］

Although the little girl was frightened，she answered in a calm voice.

虽然小女孩很害怕，但她还是用平静的声音回答。

【学法点拨】

有些使令动词，如 dress，seat，absorb 等，其过去分词无论作定语还是表语，都无被动的意味。因为 dress oneself in 等于 be dressed in；seat oneself on 等于 be seated on；absorb oneself in 等于 be absorbed in，这种现象缘于反身代词的用法：主语和宾语同为一人，主语是动作的

发出者，又是动作的承受者，这就出现了被动语态或过去分词不表

示“被动”的语言现象。

2 过去分词作状语

过去分词（短语）作状语，表示动作发生的背景或情况，其逻辑主语是句子的主语。过去分词（短语）在句中作状语可以表示时间、条件、方式或伴随、让步、原因等。

（1）表示时间   过去分词（短语）作时间状语，相当于一个时间状语从句。

Asked why he did it（=When he was asked why he did it），the monitor said it was his duty.当被问到他为什么这么做时，班长说这是他的职责。

（2）表示条件    过去分词（短语）作条件状语，相当于一个条件状语从句。

Given better attention（=If it were given better attention），the accident could have been avoided.如果当时多加注意，事故本来是可以避免的。

（3）表示方式或伴随     过去分词（短语）作方式状语或伴随状语，可以转换成一个并列句。

The patient got off the bed，（and he was）supported by the nurse.那个病人在护士的搀扶下下了床。

（4）表示让步   过去分词（短语）作让步状语，相当于一个让步状语从句。

Encouraged by his parents（=Although he was encouraged...），he still has no confidence in overcoming the difficulties. 尽管受到了父母的鼓励，他仍然没有信心克服困难。 ［词汇复现］
