过去进行时的概念:
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。
过去进行时的基本用法:
1、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。
We were expecting you yesterday. 我们昨天一直在等你。
He was playing while I was studying. 我在做功课时他在玩。
2、过去进行时表示现在:
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。
We were hoping you would stay with us. 我们很希望你能跟我们住在一起。
How much did you want to spend, sir? 先生,您打算花多少钱?
【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。
The boy was continually asking questions. 这个男孩子老是问东问西的。
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。
如: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)
过去进行时与一般过去时的区别:
(1)过去进行时强调动作在过去某时刻正在进行或持续,而一般过去时表示动作的完成。
如:He was writing his composition last night. 他昨晚在写作文。(不一定写完)
He wrote his composition last night. 他昨晚写了一篇作文。(已经写完)
(2)表示过去的状态、感觉及心理活动的静态动词(如be, like, love, hate, fear, own, hear, see, know, want, notice)可用于一般过去时,但通常不用于进行时。
如:I hated it when a man spoke with his mouth full of food. 我讨厌人们说话时口里含着食物。
(3)一般过去时与always, constantly, forever, continually等连用,表示“过去经常性、习惯性的动作”;
而过去进行时与always, constantly, forever, continually等连用,表示动作的重复,常带有感情的色彩。
如: He always got up at six. 他过去总是六点起床。
He was always thinking of his work. 他总是一心想到工作。
(4)有时过去进行时可以用来替换一般过去时,但一般过去时表示主语的行为是经过认真考虑的;
而过去进行时表示一种较随便或没有进行仔细考虑的行为。
如:I thought that he would agree with us. 我原以为它会同意我们的。
I was thinking of persuading him to follow my advice. 我想到了要说服他接受我们的建议。
注:下面几种情况不用一般过去时而要用过去进行时:
1、表示过去某一阶段暂时性的习惯动作时。
如:Tom was getting up at six o'clock every day that week. 汤姆那一周里每天都是六点钟起床。
2、与always连用表示赞美,厌烦等感情色彩时。
如:John was always coming to school late. 约翰上学总是迟到。
LeiFeng was always doing good deeds for the people. 雷锋总是为人民做好事。
3、用来描写故事发生的情景时。
如:It was a dark night. The wind was blowing hard and the rain was falling heavily. A PLA man suddenly appeared on the river bank. He wanted to cross the river.
那是一个漆黑的夜晚,风刮得很厉害,雨下得很大,一个解放军战士突然出现在河岸上,他想过河去。
4、when作并列连词,表示“(这时)突然”之意时,第一个并列分句用过去进行时,when引导的并列分句用一般过去时。
如:I was taking a walk when I met him. 我正在散步,突然遇见了他。
We were playing outside when it began to rain. 我们正在外边玩,这时下起雨来了。
5、go, come, leave, start, arrive等动词可用过去进行时表示过去将来的含义。
如:I was leaving for Wuhan that day. 那天我正要去武汉。
She was coming later. 她随后就来。
过去完成时的概念:
过去完成时既可表示过去某个时间或动作之前所发生的事情,也可表示过去某个时间或动作之 前所发生的动作一直持续到过去某个时间。过去完成时由“had+过去分词”构成。
如:She had leant 2000 English words by the end of last month.
过去完成时的应用:
(1)与过去完成时连用的时间状语可以多种多样,使用它的主要依据是看其是否发生在“过去的过去”。
如:He had learnt some English before I went here. 在来这儿之前我学过一些英语。
He had written three stories by last year.到去年他已经写了三篇故事。
We had cleaned the room when he got there. 当他到那儿时,我们已经把房子弄干净了。
He went there after he had finished his work. 他把事做完之后,就去哪儿了。
注意:当主句跟由before, after, as soon as所引导的时间从句的动作连接很紧密时,从句也可用一般过去时。
如:He went there after he read the letter. 他看了那封信后就去那儿了。
(2)过去完成时还经常用于主句为过去时的宾语从句中。
如:He said he had been a soldier. 他说他当过兵。
They said they had seen the film. 他们说这幕电影他们看过。
(3)在hardly/scarcely…when…,nosooner…than…两个结构中的主句通常要用过去完成时。
如:Hardly had I told her the news when she began to cry out. 她一听到这一消息就大哭了起来。
Scarcely had he finished his supper when he went out. 他已吃完晚饭就出去了。
No sooner had he fallen asleep than he lay down on the bed. 他一躺倒床上就睡着了。
(4)动词expect, hope, suppose, think, want等的过去完成时可用来表示未实现的计划、打算或希望。
如:I had hoped to see you. 我本希望来看你。
He had wanted to buy a house in Beijing. 他本想在北京买栋房子。
过去完成时与一般过去时:
(1)过去完成时表示以过去某时间为起点以前所发生的动作或存在的状态,即:过去完成时强调“过去的过去”,而一般过去时只表示以现在时间为起点以前所发生的事情或存在的状态。
如:He studied there two years ago. 他在那儿学习了两年。(离现在两年)
He said he had studied there two years ago. 他说他在那儿学习了两年。(离他说话时两年)
(2)表示过去某个时间以前所连续发生的两个或两个以上的动作时,一般用and, then, but按照动作的先后顺序连接,此时通常用一般过去时而不用过去完成时。
如:He said he went the shop and bought some food. 他说他去商店买了一些食品。
(3)两个动作相继发生,可用一般过去时;如第一个动作需要若干时间完成,用过去完成时。
如:When I heard the news, I was very excited.
(4)叙述历史事实,可不用过去完成时,而只用一般过去时。
如:Our teacher told us that Columbus discovered America in1492.
