Be quick ,or the train _ by the time we get to the station.为什么选will have left,考什么知识点
是 by + 将来时间------谓语动词是：将来完成时.

考3点
1.or 引导的让步状语从句，相当于if【主要是这个，一下2点都是附属】
改成if引导的从句：If we are not quick, the train will have left by the time we get to the station.
2.虚拟语气
3.时态：will have left （将来完成时，其实也是虚拟语气的时态）

全部展开

收起

这种时态叫做将来完成时，意思是在将来某个动作发生之前已经完成的动作。这句话中在我们到达车站时（将来的动作），火车已经开走了，也就是说火车在我们到达之前已经开离开了。。
