________ where to go, the old man turned to a policeman for help.
A、Having lost his way and not kmowing
B、Losing his way and didn't know
C、Lost his way and not knowing
D、Lost his way and didn't know
【正确答案】：D
【题目解析】：分词短语作状语时，其逻辑主语必须与句子的主语一致。所选部分在句中作状语，与句子的主语是主动关系，故排除C，D，“迷失道路”发生在“向警察询问”之前，故用完成时，因此此题正确答案为A.
