所有时态和形式 ：
■表示在过去某一时刻或某一动作之前已经完成了的动作,即“过去的过去”.如：

注意：过去完成时是一种相对时态,一定要有一个作参照的过去时间或过去动作作比较,否则,就不能用过去完成时.但下列3种情况虽然有是先后发生的两个过去动词,却同用一般过去时：
1. 先后发生的一系列动作,但并不强调先后时,最后两个动词用then,and,but 等连接.如：
On Saturday afternoon, Mrs Green went to the market, bought some bananas and visited her cousin. 星期下午,格林夫人去了市场,买了些香蕉,然后去看望了她的表姐.
2. 两个动作是紧接着发生的,可用一般过去时.如：
When I heard the news, I was very excited. 我听到那个消息时,非常高兴.
3. 叙述历史事实,可用一般过去时.如：
Our teacher told us that Columbus discovered America in 1492. 我们老师告诉我们哥伦布于1492年发现了美洲.
■表示从过去某一时刻开始一直延续到另一过去时刻的动作或状态.跟现在完成时一样,也常与how long, for three days, before等表示一段时间的状语连用.如：
When Jack arrived he learned Mary had been away for almost an hour. 当杰克到来时,他才了解到玛丽已经离开差不多一个小时了.
■表示未曾实现的希望或打算.表示希望或打算的动词,如hope, want, expect, think, suppose, plan, mean, intend等的过去完成时,后接不定式to do时,表示未曾实现的希望或打算,即“本来希望或打算做某事(但却没做) ”.如：
I had hoped to send him a Christmas card,but I forgot to do so. 我本来希望寄给他一张圣诞卡的,但我忘了寄了.
I had intended to come over to see you last night,but someone called and I couldn’t get away. 昨晚我本想去看你的,但有人来了我走不开.
■用于下列4个特殊句型中：
1. hardly…when…, no sooner…than…
2. It/ That /This was the first time that…
3. It was+时间段+since…(from www.yygrammar.com)
4. …than sb. had thought /expected /hoped /wanted等.

It was more than a year now since he had seen her. 他上次见她以来已经一年多了.
We arrived earlier than we had expected. 我们到得比预料的早.
■表示到现在为止已发生或完成的动作,其结果的影响现在依然存在.有时与just, already, yet, recently, before, twice, three times等时间状语连用,如：
I have seen the film already. 我已经看过那部电影了.(现在我知道电影的内容了.)
Have you seen my bag? 你看到我的手提包了吗? (你知道它在哪里? )
注意：
1. 现在完成时不与yesterday, last week, two days ago, in1983, just now, when等表示具体的过去时间的状语连用.
2. 一般过去时只强调在过去发生过某事或关注的是动作发生的时间、地点、方式等；而现在完成时则强调过去的动作对现在的影响,因此,若现在影响并不存在时就不能用现在完成时了.如说I have closed the door. 那门现在也是关着的,若被风吹开了,就只能说I closed the door. 了.
■表示从过去某一时刻开始一直持续到现在的动作或状态.常与“since+时间点”,“for+时间段”,及how long, (ever) since, ever, before, so far, in the last /past few years, up to now, till now等时间状语连用.如：
She has been a dancer for ten years. 她已当了十年的舞蹈演员了.

注意：非延续性动词leave, arrive, come, go, return, join, die, buy, borrow等的完成时,在肯定句中不能与for或since等引导的时间段连用.但其在否定式是可与这类时间状语连用的.如：I haven’t met him for two years. 我两年没有遇见他了.

■用于This/That/It is +the+形容词最高级+名词+that…句型中.如：

4. 在条件句中表示将来不用will,而用一般现在时、be going to(打算) 或be to(为人所控制的动作) 等.若你见到在条件句中用了will,那will就是表示“愿意”的情态动词.如：

注意：
1. 这与不定式作表语不同：My idea is to go there today. 我的意思是今天就去那里.
