例：
1.Seeing my parents waving in the crowd,I went running to them.
2.Crossing the road,the old man was knocked over by a car.
动词ing形式作时间状语,是不是只能表示过去的事情?
答
您好，
ing作状语时，更多表示主动
和时态基本无关
答
额.第一句话打错了吧.
第二句话,可以说是省略句.when he was crossing the road,the old man was knocked over by a car.主句的主语与从句的主语一致,主语和be动词可以省略
