【自主发现】
以上语段中,黑体部分均使用了 ;①用于 句型中,主句用过去完成时,意为“一……就……;刚……就……”;②动作发生在 之前,表示“过去的过去”;③动作用于“It was the first/second/…time that…”句型中,that从句谓语动词应使用 ;④动作有“原本打算……(但事实上并没有……)”之意。
过去完成时
1.基本结构
(1)主动语态的基本结构:
①肯定句:主语+had+动词过去分词+其他.
②否定句:主语+had+not+动词过去分词+其他.
③一般疑问句:Had+主语+动词过去分词+其他?
肯定回答:Yes, 主语+had.
否定回答:No, 主语+hadn’t.
④特殊疑问句:特殊疑问词或词组+had+主语+动词过去分词+其他?
(2)被动语态的基本结构:
主语+had (not)+been+及物动词(短语)的过去分词+其他.
2.基本用法
(1)表示在过去某个时间或动作之前就已经发生的动作,通常简称为“过去的过去”。句中常有by the end of等介词(短语)和by the time, before, when, until等引导的状语从句。如:
The concert had already begun when I hurried there.
我匆忙到那儿的时候,音乐会已经开始了。
By the end of last week, they had finished the assigned task.
到上周为止,他们已经完成了分配的任务。
(2)过去完成时表示发生在过去某个动作或时刻之前的动作一直延续到过去的另一个时间,常与for, since等词连用。如:
I had been at the bus stop for 20 minutes when a bus finally came.
我在公交车站等了20分钟,终于来了一辆公交车。
3.过去完成时在几个重点句型中的应用
(1)在no sooner…than…, hardly…when…句型中,主句用过去完成时,意为“一……就……;刚……就……”。如:
We had no sooner arrived there than the meeting began.
我们刚到那儿,会议就开始了。
I had hardly returned from work when the rain poured down.
我刚下班回来,大雨就倾盆而下。
【名师点津】
若把句型中的no sooner, hardly提前放在句首,主句用部分倒装,即把助动词had提前。如:
Hardly had we started when the car got a flat tyre.
我们才刚刚开动,汽车的轮胎就瘪了。
(2)在“It was the first/second/…time that…”句型中,that从句的谓语动词用过去完成时。如:
It was the first time that we had had that scary experience.
这是我们第一次有那样可怕的经历。
(3)表示“意愿,打算”的动词如hope, mean, want, think, expect, plan, intend等的过去完成时表示“原本……(但事实上并没有……)”之意。如:
They had planned to see us off at the airport.
他们本打算去机场给我们送行。
4.语法区别
(1)与现在完成时的区别:
现在完成时表示的动作发生在过去,以现在的时间为基点,但侧重对现在产生的结果或造成的影响;过去完成时则是一个相对的时态,以过去的时间为基点,它所表示的动作不仅发生在过去,更强调“过去的过去”,只有和过去某时或某动作相比较时,才用到它。如:
I have learned 1,000 English words so far.
到目前为止我已经学会了1000个英语单词。
I had learned 1,000 English words till then.
到那时为止我已经学会了1000个英语单词。
(2)与一般过去时的区别:
时间状语不同:过去完成时在时间上强调“过去的过去”;而一般过去时只强调过去某一特定的时间。如:
They had arrived at the station by ten yesterday.
他们昨天十点前到了车站。
They arrived at the station at ten yesterday.
他们昨天十点到达车站。
