Then he dressed their baby daughter and took the child for a walk before leaving for work.
这里不是过去式么,为什么后面要用leaving
因为:before 在……之前,是介词,而介词后的动词要用ing 形式.

再问: 那动词除了在介词后还有在什么地方要加ing
再答: 进行时态呀,或动名词作主语呀,或现在分词作状语呀,平时要多积累哦! 如 He is reading English. Reading in bed is bad for your eyes. There is a shop selling all kinds of things there .
