由when, by the time, before等引导时间状语从句时，若描述发生在过去的事，主句常用过去完成时(had + 过去分词)表示动作发生在过去的过去。
④ I was about to go up to my office
when I decided to get a coffee first.
⑤ As I was waiting in line with the
other office workers, I heard a loud
sound.
be about to do, be doing等表示即将或正在做某事时，常用when引导从句表示突然发生的动作。
过去完成时
一、概念
过去完成时表示一个动作或状态在过去某一
时间或动作之前已经完成或结束，也可能是
早已完成或结束，即“过去的过去”；也可以
指过去的动作延续到过去的某个时刻。
二、结构
“had +动词的过去分词”
三、用法
表示过去某一时间或动作之前已经发生或完成的动作或存在的状态。句中常用by, before, when, until等词引导时间状语。
它是以过去某一时间为起点，所以过去完成 时是一个相对的时态，表示的是“过去的过去”。只有和过去某时间或某动作相比较时才能用到它。
例: Most of the guests had left when he
arrived at the party.
当他到达晚会时，他发现大多数客人已经离开了。
2. 过去完成时还可表示过去某一时刻之前发生的动作或状态持续到过去某个时间或持续下去，常与for, since等词连用。
例： When Jack arrived, Mary had been away for almost an hour.
当杰克到时，玛丽已经离开快一个小时了。
