主句动作发生在从句之后，从句是一般过去时， 主句为过去完成时。
两个动作同时进行，主从句都是一般过去时或过去进行时。
观察以下句子，发现其中的时态规律。
一、概念： 过去完成时由“助动词had（用于各种人称和数）+过去分词”构成，表示某动作或状态在过去某一时间或动作之前已经发生或完成，它表示动作发生的时间是“过去的过去”。
1. 表示一个动作或状态在过去某一时间或动作之前已经发生或完成，常与 by、befre等构成的表示时间的短语连用。►By the time I went utside, the rain had already stpped. 我走到外面时，雨已经停了。►He threw it int the sea befre he realized what he had dne. 在他意识到他所做的事情之前，他已经把它扔进了海里。2. 常用在said、tld、knew、heard、realized等后面的宾语从句中。►He said that he had wrked in that factry fr ten years. 他说他已经在那家工厂工作了十年。►I suddenly realized that I had left my ID card at hme. 我突然意识到我把身份证忘在家里了。
3.在含有when、befre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时，主句常用过去完成时。►The cncert had ended when she arrived there. 当她到达那里时，音乐会已经结束了。►She had learned English befre she came t America. 她来美国之前学过英文。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。►I met Jim in the street yesterday. We hadn’t seen each ther since he went t Beijing. 我昨天在街上碰见了吉姆，自从他去北京以后，我们彼此就没有见过面。
1. 句中有yesterday、last year、in 1990、three years ag等明确表示过去的时间状语时，常用一般过去时，而不用过去完成时。►He said his grandpa died in 1999. 他说他的爷爷是1999年去世的。2.叙述过去连续发生的两件及两件以上的事情时，虽然时间上有先后之别，但仍用一般过去时。►They decided t stay there, s they built their huse and gt married. 他们决定留在那儿，所以他们建了房子，并结了婚。3.在包含befre、after、when、until、as sn as等引导的时间状语从句的复合句中，如果主句的动作和从句的动作紧接着发生，那么主、从句均使用一般过去时。►Where did yu study befre yu came here? 你来这儿之前在哪儿学习？►He tk ut his English bk as sn as he sat dwn. 他一坐下就拿出了英语书。
四、 不用过去完成时的几种情况：
