一、过去完成时的概念与结构特点:
概念: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,即“过去的过去”。
构成:过去完成时由“had + 过去分词”构成,其中 had 通用于各种人称。
肯定/否定句:主语+had / hadn’t +过去分词+…
一般疑问句:Had +主语+过去分词…?
(Yes, 主语+had. / No, 主语+hadn’t.)
特殊疑问句:疑问词+had +主语+过去分词+…?
过去完成时
6:00 7:00 现在
By the time I got up, my sister had already washed all the clothes.
用法
含有when/before/after/until引导的时间状语从句
(1) 用于两个先后发生的动作
The train had left before I reached the station.
Mary was sent to Shanghai after her girlfriend had been sent to Beijing.
Teacher had left when his students finished the homework.
(2) 用于told, said, knew, heard, thought等后的宾语从句,从句的动作发生在主句之前。
He said that he had met her before.
我还了我借的那本书。
(3) 含有定语从句的句子,如果叙述的是过去,先发生的用过去完成时。
I returned the book
that I had borrowed.
She said that she had seen the film before.
翻译下列句子
1、他说他完成作业了。
He said that he had finished the homework.
2、我们认为日本要为他们所做的负责(pay for)。
We thought that Japan should pay for what they had done.
3、老师知道了Jack做过的事。
Teacher knew that what Jack had done.
二、过去完成时的判断依据:
1. 由时间状语来判定:表示动作从过去持续到过去一段时间。与过去完成时连用的时间状语有:
(1) by + 过去的时间点。到……时/前 如:
到昨天晚上九点前我已经读完这本小说了。
I had finished reading the novel by nine o'clock last night.
(2) by the end of + 过去的时间点。如:
截止到上学期末,我们已经学了两千多个英文单词了。
We had learned over two thousand English words by the end of last term.
(3) before + 过去的时间点。如:
上周三以前他们已经种了六百棵树了。
They had planted six hundred trees before last Wednesday.
常用的时间状语等标志词:
1、by,、before,、when、by the time、by the end of等
构成的短语或引导的从句。
常用的宾语从句引导词:
2、由said、told、knew、heard、thought 等
引导的宾语从句中。
2. 由“过去的过去”来判定:
①过去完成时表示“过去的过去”,
②是指过去某一动作之前、已经发生或完成的动作,
③即动作有先后关系,
④动作在前的用过去完成时,在后的用一般过去时。
