过去完成时表示在过去某一时间或动作之前已经发生或完成了的动作。
它表示句子中描述的动作发生在“过去的过去”。
具体如下:
过去完成时的基本用法
(1)表示在过去某一时刻或动作以前完成了的动作,即“过去的过去”。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,还可能通过上下文来表示。例如:
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200 张飞船发来的图片。
(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。例如:
I had been at the bus stop for 20 minutes when a bus finally
came.当车来的时候,我在车站已等了20分钟。
He said he had worked in that factory since 1949.他说自从1949年以来他就在那家工厂工作。
(3)叙述过去发生的事情,在已叙述了过去发生的事情后,反过来追述或补述以前发生的动作时,常使用过去完成时。例如:
Mr. Smith died yesterday. He had been a good friend of
mine.史密斯先生昨天去世了。他以前是我的好友。
I didn’t know a thing about the verbs, for I had not studied my
lesson.我对动词一无所知,因为我没有好好学习功课。
(4)在含有定语从句的主从复合句中,如果叙述的是过去的事,先发生的动作常用过去完成时。例如:
I returned the book that I had borrowed.我已归还了我借的书。
She found the key that she had lost.她丢失的钥匙找到了。
(5)过去完成时常常用在宾语从句(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。例如:
He said that he had known her well.他说他很熟悉她。
I thought I had sent the letter a week before. 我认为我一星期前就把信寄出去了。
(6)在包含有when,
until等连词的复合句中,如果主句谓语动词和从句谓语动词所表示的过去动作不是同时发生的,那么先发生的动作通常用过去完成时表示。例如:
When I woke up, it had already stopped raining.我醒来时雨已停了。
She didn’t go to bed until she had finished he work.她直到把工作做完之后才睡觉。
注意:如果两个动作紧接着发生,则常常不用过去完成时,特别是在包含before和after的复合句中,因为这时从句的动作和主句的动作发生的先后顺序已经非常明确,这时可以用一般过去时代替过去完成时。例如:
After he arrived in England, Marx worked hard to improve his
English.马克思到达英格兰之后,努力提高他的英语水平。
(7)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。例如:
They had wanted to help but could not get there in
time.他们本来打算去帮忙,但没有及时赶到那里。
We had hoped to be able to come and see you .我们本来希望能来看看你。
(8)过去完成时还可用在hardly…when…, no sooner…than…, It was the first (second, etc)
time (that)…等固定句型中。例如:
Hardly had he began to speak when the audience interrupted
him.他刚开始演讲,听众就打断了他。
No sooner had he arrived than he went away again.他刚到就又走了。
It was the third time that he had been out of work that year.这是他那一年第三次失业了。

过去的过去对过去的影响
形式为
had+过去分词

had had

在过去的时间前已经发生的事,标志为 by +过去时间

这跟语法里的过去式和过去完成式有关系。
过去式,就是已经做过的事情。比如:我昨天打扫房间了。I cleaned this room yesterday.
过去完成式,就是“过去的过去”,语法形式是have+过去分词。比如:昨天吃晚饭之前我已经打扫房间了。I have cleaned this room before dinner yesterday.
考试里过去完成式...

这跟语法里的过去式和过去完成式有关系。

过去完成式,就是“过去的过去”,语法形式是have+过去分词。比如:昨天吃晚饭之前我已经打扫房间了。I have cleaned this room before dinner yesterday.
考试里过去完成式比较典型的特点是有“已经”,中文译句里面有“已经”出现,一般都要用到过去完成式。
所以背动词时态的时候是“原型-过去式-过去分词”的形式背。上面例子里的clean的过去式和过去分词是一样的,即clean-cleaned-cleaned
不一样的例如drink:drink-drank-drunk
过去事是指过去发生的事情一般不影响到现在过去分词也用过去,但过去的事情影响到现在或者一直延续到现在(就是完成时)
一般跟在HAVE后面,但过去的事情影响到现在是HAVE +过去分词过去一直延续到现在HAVE BEEN DOING

收起

现在完成时态是have+done或者has+done
变成过去完成时当然是had+done拉!

had+PP.

应该是现在完成时态
主语+had+时间状语+过去分词

在过去(这段时间)之前的时间完成的是情。如前天做的是相对于昨天就是过去的过去,就要用过去完成时
