过去完成时
定义
构成
用法
判断依据
By the time I got back to school, the bell had rung.
一般过去式
从句
主句
过去完成时
动作发生在后
动作发生在前
在过去某个时间或某个动作之前发生的动作或存在的状态，它表示动作发生的时间是“过去的过去”。
定义
肯定句：
否定句：
一般疑问句：
构成
构成：___________________________
助动词had+动词的过去分词
主语+had+过去分词+其他.
主语+hadn’t(had not)+过去分词+其他.
—Had+主语+过去分词+其他
—Yes, 主语+had./ No, 主语+hadn’t.
(1)表示某一动作或状态在过去某一时间或动作之前已经发生或完成，即发生在“过去的过去”。这个过去的时间常与by, before等构成的短语连用。
例：我睡醒时我的父母已经开始工作了。
My parents had begun to work by the time
I woke up.
用法
(2)过去完成时用在told, said, knew, heard, thought 等后面的宾语从句中。
例：约翰说它拥有这辆自行车五年了。
John said he had had the bike for five years.
根据句意，写出括号内所给单词的适当形式。
You told me you had ______(deal) with these letters.
Why are they still here
中考链接
【中考】
dealt
(3)在含有时间、原因、方式等状语从句的复合句中，主、从句的动作都发生在过去，且有明显的先后关系，动作在前的要用过去完成时，动作在后的要用一般过去时。
例：迈克不想再吃鸡肉了，因为他已经吃够了。
Mike wanted no more chicken because he
had had enough.
After he turned off the light, he had left the room. ( )
After he turned off the light, he left the room. ( )
思考
判断正误
注意：在由before, after 引导的时间状语从句的复合句中，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、从句都可用一般过去时。
(4)一般可根据上下文语境来确定过去完成时的时态。
例：尽管他失败了很多次，但他从没放弃过。
Although he had failed many times, he
never gave up.
(1)由时间状语来判定
① by+过去的时间点
例：到昨天9点钟时，她已经读完了这本书。
She had finished reading the book by 9
o’clock yesterday.
判断依据
② by the end of+过去的时间点
例：到上个月月底，我们已经完成了所有工作。
We had completed all the work by the end of last month.
翻译：
她说她之前看过了这部电影。
___________________________________________
当我到达车站的时候，火车已经走了。
____________________________________________
(2)由“过去的过去”来判定
She said that she had seen the film before.
When I got to the station, the train had already left.
