用法
过去分词在句子中作状语,可以表示时间、条件、让步、原因、方式、伴随等。过去分词作状语时,它的逻辑主语一般就是句子的主语。
1.时间状语:相当于when、while等引导的时间状语从句,有时过去分词前可加when、while等来强调时间概念。
Seen from the moon the earth is beautiful从月球上看时,地球是漂亮的。
2原因状语:相当于as、since、because引导的原因状语从句。
Satisfied with what he did,the teacher praised him in class.
由于对他所做的事情感到满意,老师在班上表扬了他。
3条件状语:相当于if、unless等引导的条件状语从句。
Given more time we would have done the work better如果给我们更多的时间,我们会把这项工作做得更好。
4.让步状语:相当于 although、though、even if/though等引导的让步状语从句。
Laughed at by many people,he continued his study.
尽管被许多人嘲笑,他还是继续他的研究。
5方式状语或伴随状语:作伴随状语或方式状语的过去分词没有
对应的状语从句,但可转化为并列分句
The old man went into the room supported by his wife.那个老人在他妻子的搀扶下走进了房间。
温馨提示
1过去分词短语作状语时,可在分词之前加某些连词,以表示
强调。常用的有if、unless when,once、until、though/although,even if even though、as、as if等
2.如果句子的主语不是过去分词的逻辑主语,那么作状语的过去分词前要加上自己的逻辑主语,这种带逻辑主语的过去分词结构属于独立主格结构。
例My 10-year-old daughter was lying on the ground urround)by some broken scooter parts思路点拨句意:我十岁的女儿躺在地上,周围是一些坏了的滑板车部件。主语My l0-year-old daughter与 surround之间为逻辑上的被动关系,所以用过去分词短语作状语。
