Summary

1) 过去分词在句子中可以作时间状语、原因状语、伴随状语、条件状语和让步状语等。

2) 过去分词作状语时,过去分词的逻辑主语与句子主语一致。

过去分词作状语:

1. 表示被动的动作；

2. 表示已经完成的动作, 因此,当过去分词作状语的时候一定要搞清楚分词与主语的逻辑关系－－被动,

※ 分析并翻译下面的句子。（划线部分的作用）

1 ：Asked what had happened, he told us about it.

2：Well known for his expert advice, he received many invitations to give lectures.

3；United we stand, divided we fail.
