(2)过去完成时的构成 过去完成时是由“助动词had＋动词的过去分词”构成的，had用于各种人称和数。如： She had arrived at the village befre 8 'clck last night. 昨晚8点之前她就到达了这个村庄。
(3)过去完成时的句式 过去完成时的否定句是在had后加nt；一般疑问句是将had移至句首，其肯定回答为：Yes，主语＋had.；否定回答为：N，主语＋hadn't.。如： ①Her little brther hadn't gne int the bathrm by the time she gt up. 她起床时，她弟弟还没有进入浴室。
②—Had yu started teaching when she gt int the classrm? 她走进教室时，你已经开始讲课了吗？ —Yes, I had./N, I hadn't. 是的，我开始讲了。/不，我还没有开始讲。
(4)过去完成时的标志 1)用于表示过去某一时刻前已经发生的动作或状态，常与by, befre, after, until, when等引导的过去时间状语连用。如： ①They had cllected ver 1，000 stamps by the end f last mnth. 到上个月月底，他们已经收集了1000多张邮票。 ②The bus had already left by the time I gt utside. 我出去时，公共汽车已经开走了。

【注意】如果时间状语从句的动作发生在主句之前，则从句用过去完成时，主句用一般过去时。如： My watch went well after I'd had it repaired. 我的手表修好了以后，走得很准。 2)过去完成时用于宾语从句中，表示从句的动作或状态发生在主句的谓语动词的动作之前。如： He tld me that he had heard f the gd news. 他告诉我他已经听说了那个好消息。
有时过去完成时也用在其他从句中。如： What he had said made me angry. 他说的话真让我生气。(用在主语从句中) 3)有时句子中没有明显的时间状语，动作发生的时间先后需根据上下文去判断。如： She was very happy. Her whle family were pleased with her, t. She had just wn the first place in the game. 她非常高兴。她的全家人也对她感到满意。她刚刚在比赛中获得了第一名。
(5)过去完成时的持续用法 表示过去某一时间之前发生的动作或存在的状态一直持续到过去某一时间，并有可能继续下去。常与由fr或since引导的表示一段时间的短语或从句连用，此时要把短暂性动词改成持续性动词。如： ①He had wrked in the factry since it pened in 1996. 自1996年工厂建成以来，他一直在这儿工作。
