They had arrived at the station by ten yesterday.
They arrived at the station at ten yesterday.
2. 在没有明确的过去时间状语作标志时,谓语动词动作发生的时间先后须依据上下文来判断:先发生的用过去完成时,后发生的则用一般过去时。如:
She was very happy. Her whole family were pleased with her, too. She had just won the first in the composition competition.
3. 当两个或两个以上接连发生的动作用 and 或 but 连接时,按时间顺序,只需用一般过去时来代替过去完成时;另外,在 before , after , as soon as 引导的从句中,由于这些连词本身已经表示出时间的先后,因此也可以用过去时来代替过去完成时。如:
He entered the room, turned on the light and read an evening paper.
I (had) called her before I left the office. 过去完成时
