过去进行时
1. 过去进行时的定义
过去进行时主要表示过去某一时刻正在进行的动作,或表示过去某一阶段一直在进行的动作。如:
I was having a talk with Li Hua at that time. 那时,我正在跟李华谈话。
I was watching TV at home last night. 昨晚我一直在看电视。
2. 过去进行时的结构
过去进行时由“was / were + 现在分词”构成。如:
I was doing my lessons then. 那时,我在做功课。
We were cleaning the house. 我们在打扫房子。
3. 使用过去进行时应注意的几点
(1) 过去进行时可表示按计划、安排过去某时刻将要发生的动作。如:
He said they were leaving for Beijing this afternoon. 他说他今天下午要去北京。
(2) 动词hope, wonder等的过去进行时常用来表示提出要求,虽然表示现在的内容,但语气比一般现在时或一般过去时要委婉。如:
I was wondering whether you could come to join us. 我想你能否过来跟我们一起活动?
(3) 过去进行时中有always, forever, continually, constantly修饰时,表示说话人的赞赏或厌烦的感情。如:
He was always thinking of others. 他总是想到人家。
4. 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****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
过去进行时的时间状语
1. when 和while引导的状语从句中,强调某个动作正在进行的过程中时要用进行时态,while表示一段时间,因此它所引导的状语从句中,谓语动词常用进行时态,如:
When/While we were having supper, the light went out. 我们正在吃饭时灯熄灭了。
2. when用作并列连词时,主句常用进行时态,从句则用一般过去时,表示主句动作发生的过程中,另一个意想不到的动作发生了。如:
I was walking in the street when someone called me. 我正在街上走时突然有人喊我。
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。
Lei Feng 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:
