1.before
I thought I had sent the letter a week before.
2.by
By nine o’clock last night, we had got 200 pictures from the spaceship.
3.过去完成时常常用在told,said,knew,heard,thought等动词后的宾语从句（或间接引语）中，这时从句中的动作发生在主句表示的过去的动作之前。
4.since
He said he had worked in that factory since 1949.
5.过去完成时还可用在hardly…when…, no sooner…than…, It was the first (second, etc) time (that)…等固定句型中。本回答被提问者和网友采纳
