I had reached the station before 9:00 oclock. I had not reached the station before 9:00 oclock. Had you reached the station before 9:00 oclock? 4、它通常和before, by the end of 等引导的表示过去的时间状语连用. 另外, 复合句的主句为一般过去时, 宾语从句表达过去发生的动作时,从句也要用过去完成时. E.g. He said he had never seen such an exciting match before. 过去完成时需要与一个表示过去的时间状语连用，它不能离开过去时间而独立存在。此时多与 already ， yet ， still ， just ， before ， never 等时
