Grammar Focus
主句为过去完成时，从句是一般过去时，主句动作发生在从句之前。
两个动作同时进行，主从句都是一般过去时或过去进行时。
When I got to school, I realized that I had left my backpack at home.
By the time I got back to school, the bell had rung.
Before I got to the bus stop, the bus had already left.
I was about to go up to my office when I decided to get a coffee first.
As I was waiting in line with the other office workers, I heard a loud sound.
过去完成时：用来描述在过去某一时间或动作之前已经发生或完成了的动作。(过去的过去)
由“助动词had (用于各种人称和数) + 过去分词”构成。否定式：had not + 过去分词 。缩写形式：hadn’t + 过去分词 。
过去完成时
肯定句 主语 + had + 过去分词 + 其他.
否定句 主语 + hadn’t + 过去分词 + 其他.
一般疑问句 Had+ 主语 + 过去分词 + 其他
肯定回答：Yes, 主语 + had. /否定回答：No, 主语 + hadn’t.
特殊疑问句

句式
用法
表示一个动作或状态在过去某一时间动作之前已经发生或完成，常与by、 before等构成的时间短语连用。
主句是一般过去时的宾语从句中。
(3) 在含有when、 before等引导的时间状语从句的复合句中， 如果从句的时态为一般过去式，主句常用过去完成时。
(4) 过去完成时是一个相对的时态，只有和过去的某个时间或动作相比较时才会用到，因此可通过分析语境来确定时态。
过去完成时与一般过去时的区别
一般过去时表示过去某时间发生的动作或存在的状态；
过去完成时则表示过去某一时间以前（即过去的过去）发生的动作或存在的状态。
