  • 过去进行时
  • 过去完成时
过去进行时:
表示在过去某一时刻或某一段时间内进行或发生的动作。其形式为was/were+V-ing。
常与表示过去的时间状语连用,如:
last night,last Saturday等;
或者与when,while,as引导的过去时间状语连用。
过去进行时的结构:
1. 过去进行时由“主语+was/were + 现在分词”构成
eg: We were having supper when the phone rang. 我们正在吃晚饭时电话响了。
2. 过去进行时的否定式由“主语+was/were not +现在分词”构成
eg: This time yesterday Jack was not watching TV. He was repairing his bike. 昨天这个时候,杰克不是在看电视,而是在修理自行车。
3. 过去进行时的疑问式由“was/were +主语+ 现在分词”组成
eg: Were you playing basketball at four yesterday afternoon? 你们在干什么昨天下午的时间啊  回答我啊?

过去进行时和一般过去时的区别:
一、二者概念理解
一般过去时叙述旧事,过去进行时描述背景。
A、一般过去时
1.过去状态、动作或事件
He went to Beijing the other day.(带具体时间)
2.过去的习惯
a would ,used to与过去时
would 表间断性不规则的习惯,常带频率时间
used to 表一贯性有规律的习惯
They used to meet and would sometimes exchange one or two words.
He smoked a lot two years ago. (过去行为)
bWould 用于文中不用于句首,只表过去习惯。
Used to 表今昔对比的含义,叙述习惯动作可与would 换用。
When he was a boy , he would often go there . (叙述过去)
She isn't what she used to be. (今昔对比)
c 表示状态时一般只用used to
Tom used to be fat /There used to stand a tree there. (状态)
dwas (were) used to +ving表示“合适于,适应于…..”
He used to work at night . (“习惯”表经常)
He was used to working at night. (习惯表适应)
3.过去的经历,平行动作,依此事件用一般过去时。
He sat there and listened to the radio.(依此发生)
4.客气委婉的语气,用于情态动词,助动词和want , wonder , hope 等
How did you like the film? / Could you help me?

B. 过去进行时
1.在过去某阶段或某一时刻正在发生
What were you doing at 8:30 last night? (过去某时刻正在发生)
2.性动词用过去进行时表示按计划、打算
During that time he was going with us.(表示打算)
3.lways ,often ,usually 等连用表喜爱,讨厌等感情色彩。
He was always Changing his mind.

二、区别
A. 进行时表某一行为的“片断”一般时表示行为的“整体”和存在的状态。
I was reading the book at that time. (未读完,“读”的片段)
I read the book yesterday. (已读完,表整个“读”)
B、一般持续时间状语多与进行时连用
It was raining all night.(优先用was raining ,rained 为持续动词,故也可使用)
He was writing a letter the whole of afternoon. (短暂动词与持续时间连用,表反复,连续发生,不可用一般过去时)
C、while 时间状语从句中用短暂动词时只能用进行时。
例:He broke a chair while he was jumping up and down.
D、While 所在主从句动作大致持续相等时主从句一般都用进行时,但若是持续动词可都用一般过去时,两个动作一长一短时短的用一般时,长的用进行时。
I was cooking the dinner while he was playing the piano.(平行)
I cooked the dinner while he played the piano.
I saw him while I was walking to the station.


过去进行时的基本用法:
过去进行时的基本用法主要表示过去某一时间正在进行的动作。如:
He fell asleep when he was reading. 他看书时睡着了。   
2. 用过去进行时表示现在主要是为了使语气委婉、客气。如:
I was wondering if you could give me a lift. 我不知你能否让我搭一下车。   
【注】一般过去时也有类似用法,但比较而言,用过去进行时显得更客气,更不肯定。   
3. 过去进行时表示感情色彩与现在进行时相似,过去进行时也可表示满意、称赞、惊讶、 
厌恶等感情色彩,也通常与 always, forever, continually等副词连用。如:
They were always quarrelling. 他们老是吵架。   
4. 动词be的过去进行时动词be的进行时也可表示过去一时的表现或暂时的状态。   
比较:He was friendly. 他很友好。(指过去长期如此)   
   He was being friendly. 他当时显得很友好。(指当时一时的表现)

特殊用法

1、当句子意思很清楚时,我们也可以把两个动词都换成一般过去时
We listened carefully when the teacher read the text. 老师读课文时,我们都仔细地听着。
2、表示按计划、安排过去将要发生的事。
用于come,go,leave,start,arrive等表示位置转移的动词时,也可以用过去进行时表示过去将要发生的动作。
如:He told me that he was going soon. 他告诉我他很快就要走了。
3、表示故事发生的背景。
It was snowing as the medical team made its way to the front.
那支医疗小组往前线行进时,天正下着雪。
4、表示一个新的动作刚刚开始。
过去进行时可用来引出一个新的动作,这种用法颇有点儿像镜头转换。
Five minutes later,he stood in the doorway smoking a cigarette.
5分钟后,他已站在门口抽着烟。
5、过去进行时还可和when结构遥相呼应,含有意外之意。
I was walking in the street when someone called me.
我正在街上走时突然有人喊我。
6、用来陈述原因或用作借口。
She went to the doctor yesterday. She was having a lot of trouble with her heart.
她昨天去看病了。她患了很严重的心脏病。
7、与always,constantly等词连用,表示感情色彩。
The girl was always changing her mind.
这女孩老是改变主意。


过去完成时:
是把时间推移到过去某一时间之前,与现在不发生联系,由"had+-ed分词"构成。

基本结构:
主语+had+过去分词vpp.(done)
①肯定句:主语+had+过去分词+其他.
②否定句:主语+had+not+过去分词+其他.
③一般疑问句:Had+主语+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+一般疑问句(Had+主语+过去分词+其他)?
⑤被动语态:主语+had(hadn't)+been+过去分词+其他

过去完成时基本用法:
(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。
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。
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。
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
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。
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。
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。
(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。
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。
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。


过去完成时与现在完成时的区别:
现在完成时表示的动作发生在过去,但侧重对现在产生的结果或造成的影响,与现在有关,其结构为“助动词 have (has) + 过去分词”;
过去完成时则是一个相对的时态,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。
比较:I have learned 1000 English words so far.到目前为止我已经学会了 1000 个英语单词。
I had learned 1000 English words till then.到那时为止我已经学会了 1000 个英语单词。
— I'm sorry to keep you waiting. 对不起,让你久等了。
— Oh, not at all. I have been here only a few minutes.没什么,我只等了几分钟。(“等”的动作从过去某一时间点持续到现在)

过去完成时与一般过去时的区别:
虽然这两种时态都表示过去发生的动作或存在的状态,但在使用时应注意以下几点:
1. 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。
比较:They had arrived at the station by ten yesterday.
They arrived at the station at ten yesterday.
2. 在没有明确的过去时间状语作标志时,谓语动词动作发生的时间先后须依据上下文来判断:先发生的用过去完成时,后发生的则用一般过去时。
She was very happy. Her whole family were pleased with her, too. She had just won the first in the composition competition.
3. 当两个或两个以上接连发生的动作用 and 或 but 连接时,按时间顺序,只需用一般过去时来代替过去完成时;另外,在 before , after , as soon as 引导的从句中,由于这些连词本身已经表示出时间的先后,因此也可以用过去时来代替过去完成时。
He entered the room, turned on the light and read an evening paper.

语法判定:
一、由时间状语来判定
一般说来,各种时态都有特定的时间状语。与过去完成时连用的时间状语有:
(1) by + 过去的时间点。如:
I had finished reading the novel by nine o'clock last night.
(2) by the end of + 过去的时间点。如:
We had learned over two thousand English words by the end of last term.
(3) before + 过去的时间点。如:
They had planted six hundred trees before last Wednesday.

二、由“过去的过去”来判定
过去完成时表示“过去的过去”,是指过去某一动作之前已经发生或完成的动作,即动作有先后关系,动作在前的用过去完成时,在后的用一般过去时。这种用法常出现在:
(1)宾语从句中
当宾语从句的主句为一般过去时,且从句的动作先于主句的动作时,从句要用过去完成时。在told, said, knew, heard, thought等动词后的宾语从句。如:
She said that she had seen the film before.
(2)状语从句中
在时间、条件、原因、方式等状语从句中,主、从句的动作发生有先后关系,动作在前的,要用过去完成时,动作在后的要用一般过去时。如:
After he had finished his homework, he went to bed.
注意: before, after 引导的时间状语从句中,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、从句都用一般过去时。如:
After he closed the door, he left the classroom.
(3)表示意向的动词,如hope, wish, expect, think, intend, mean, suppose等,用过去完成时表示"原本…,未能…"
We had hoped that you would come, but you didn't.
