A. reached ; left

B. reached ; had left

C. arrived ; had gone

D. got ; had been away

答案：

A. reached ; left

(答案→)B. reached ; had left

C. arrived ; had gone

D. got ; had been away

解析：本题考查时态，.第一空填 got to或 reached 都可以的，都是到达某地，都是一般过去式；第二空，也就是在他到站前，火车已经离开了，他到站用的是过去式，那么，火车的离开应该是过去的过去，即过去完成时。在他达到火车站前，火车（已经离开）了。
