过去完成时由“助动词had+动词的过去分词”构成。过去完成时表示一个动作或状态在过去的某一时间或动作之前已经完成或结束,即发生在“过去的过去”;也可表示从过去某一时间开始的动作或状态一直持续到过去的另一时间。
过去完成时常与by、for、before、since等构成的表示时间的介词短语或由after、before、since、when、by the time等引导的时间状语从句连用。
一、过去完成时的定义和构成
now
Mary got up.

用法2：表示发生在“过去的过去”的动作，一直延续到过去的某个时间。
1.在包含when、before、after、until等连词的主从复合句中,如果主句谓语和从句谓语表示的过去动作是在不同时间发生的,那么先发生的动作通常需要用过去完成时,后发生的动作用一般过去时。
二、过去完成时的基本用法

小男孩在妈妈下班回来之前就完成了作业。
After they ______________(complete)the decoration of the classroom,it took on a extremely beautiful and festive appearance.

2.在told、said、knew、heard、thought等动词后的宾语从句或间接引语中,常用过去完成时表示从句中的动作发生在主句中的过去动作之前。
Tom told his friend that he had visited the Great Wall twice by the end of last year.
汤姆告诉他的朋友,到去年年底他已经参观过长城两次了。
3.当think、want、hope、mean、plan、intend、wish、expect等动词表示
“过去未曾/没有实现的想法/希望/打算/意图等”时,常用过去完成时。
They had hoped to reach the destination before sunset,but the traffic jam held them up.
他们原本希望在日落前到达目的地,但交通堵塞使他们耽搁了。
The Students’ Union had meant to organise a music festival to showcase the diverse talents of the students.
学生会原本打算组织一场音乐节活动,让学生展示各种才艺。
4.在条件状语从句中,表示与过去事实相反的假设时,从句要用过去完成时。
If they had left earlier,they would have caught the first train.
如果他们离开得更早一些,他们就能赶上第一班火车了。
5.在表示“一……就……”的两个句型“scarcely/hardly...when...”和“no sooner...than...”中,scarcely、hardly、no sooner所在主句中的谓语动词应用过去完成时,而when、than引导的从句应用一般过去时。

雨刚一停,人们就从家里出来享受新鲜空气。
用于hardly... when ... 和 no sooner… than ... 句型中，主句用过去完成时，when和than从句用一般过去时，表示“一…就…, 刚…就…”。当no sooner或hardly位于句首时，句子要部分倒装,即: had+主语+done… ★ ★ ★

④他一坐下，电话铃就响了。
No sooner __________________ than the telephone rang.

since 从句”句型中,从句常用过去完成时。
