去”，如句1、句2、句3和句4。
完成
（3）过去完成时可以指过去的动作延续到______的某个时刻，如句5和句6。
过去
探究点 过去完成时
一、过去完成时的构成
过去完成时由“had+过去分词”构成。
二、过去完成时的用法
1.过去完成时表示过去某一时刻或动作之前已完成的动作或存在的状态。可以用by、before等介词短语或一个时间状语从句来表示，也可以用一个表示过去的动作来表示，还可通过上下文来表示。
When the explorer hurried to the destination，the others had already left.
当这名探险者匆忙赶到目的地的时候，其他人已经离开了。
By nine o'clock last night，we had got 200 pictures from the spaceship.
到昨晚9点钟，我们已经收到宇宙飞船发来的200张图片。
2.表示由过去的某一时刻开始，一直延续到过去另一时间的动作或状态，常和for、since构成的时间状语连用。
He told us that he had done the scientific research for 5 years.
他告诉我们他做科学研究已经5年了。
3.动词think、want、hope、mean、plan、intend等用过去完成时来表示过去未曾实现的想法、希望、打算或意图等。
I had never thought that you were content to help me.
我从未想过你愿意帮我。
We had hoped to be able to come and see you.
我们本来希望能来看看你。
4.过去完成时常常用在told、said、knew、heard、thought等动词后的宾语从句（或间接引语）中，这时从句中的动作发生在主句表示的过去的动作之前。
He said that he had known her well.
他说他对她很熟悉。
5.当时间状语从句与主句的动作都发生在过去时，如果从句动作发生在主句动作之前，从句用过去完成时；如果从句动作发生在主句动作之后，则从句用一般过去时。从句常由when、before、after、as soon as、till/until引导。
When I woke up，it had already stopped raining.
我醒来时，雨已停了。
After we had finished the work， we went home.
完成工作之后，我们回家了。
注意：在before、after引导的时间状语从句中，由于before和after本身已表达了动作的先后关系，若主、从句表示的动作紧密相连，则主、从句多用一般过去时。
After he arrived in England，he worked hard to improve his English.
他到达英格兰之后努力提高他的英语水平。
6.过去完成时的常用固定句型
（1）主语+had hardly/scarcely/no sooner+过去分词+when/than从句（从句用一般过去时）；当hardly、scarcely、no sooner等表示否定意义的词位于句首时，主句要倒装。
I had no sooner reached home than it began to rain.
=No sooner had I reached home than it began to rain.
我刚到家就下雨了。
（2）It was+一段时间+since从句（从句用过去完成时）
It was at least three months since I had left Beijing.
我离开北京至少有3个月了。
（3）It was the first/second/...time+（that）从句（从句用过去完成时）
It was the first time that I had chatted online in English.
那是我第一次用英语在网上聊天。
（4）主句（过去完成时）+by the time...（一般过去时）
We had got everything ready by the time they arrived.
在他们到达之前，我们已经做好一切准备了。
（5）句子（过去完成时）+by the end of...（表示过去的时间）
By the end of last term，we had learned English at least for four years.
到上个学期末，我们至少已经学了四年英语。
7.过去完成时和过去完成进行时的区别
过去完成进行时强调动作的持续性，过去完成时表示在过去某一具体时间或动作之前已经发生或完成的动作，强调动作已结束这一事实。
They had been building the road by the end of last month.
到上个月月底为止，他们一直在修建这条路。
They had built the road by the end of last month.
截至上个月月底，他们已建好了这条路。
