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。如果其逻辑主语与整个句子的主语不一致时，需要独立主格结构或with复合结构来替代。（此时，也可把该分词看成介词的宾语补足语。）例：

The murderer was brought in, with his hands ___ behind his back.

A. being tied B. having tied C. to be tied D. tied

简析：很显然，待选部分的逻辑主语是his hands，而不是句子的主语The murderer，而his hands对于动词tie来说，只能是被动承受。因此，该题应选D。

注：过去分词有两大特点：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。例如：
