While we_____(wait)for the bus,a girl _____(run) up to us后面那个填ran还是is running?为什么?
were waiting
ran 过去式
正当我们在等公交车的时候突然一个小女孩跑过来
前面的“等”是段时间,后面的“跑”是点时间

While we__were waiting ___(wait)for the bus, a girl ___ran__(run) up to us
While we__are waiting___(wait)for the bus, a girl __runs___(run) up to us

were waiting , ran
因为是过去时

填ran。在while所引导的时间状语从句中，wait是个有计划的一直发生的动作，而主句的ran的个突发的动作，故用一般过去时表达。
