资源描述

1、过去进行时,基本概念: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。,结构,现在分词的构成 1) 一般动词在词尾加- ing, 读i,如go - going。 2) 以不发音字母e结尾的动词,先去掉e,再加-ing。 come - coming make-making write - writing,3) 以重读闭音节结尾的动词,如果末尾以一个辅音字母结尾,应先双写这个字母,再加ing, x和w结尾的除外。 如: get - getting swim - swimming show - showing,4) 以字母y结尾的单词,直接加ing。 如carrying、playing、

2、studying。 5) 以字母ie结尾的动词,变ie为y,再加ing。 diedying lielying,用法,1. 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. 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。能否让我搭一下车。,3. 过去进行时表示感情色彩与现在进行时相似,过去进

3、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),一般过去时与过去进行时的区别,1、一般过时往往表示某一动作已经完成,而过去进行时却表示动作在持续或未完成。 比较: She wrote a letter to her

4、friend last night. 她昨晚给朋友写了封信。 (信写完了) She was writing a letter to her friend last night. 她昨晚一直在给朋友写信。 (信不一定写完),2、一般过去时表示只做一次动作,而过去进行时却表示动作反复地进行。 如: She waved to me. 她朝我挥了挥手。 She was waving to me. 她一直朝我挥手。,3、句中有a moment ago,this morning, the whole morning, all day yesterday, from nine to ten last eve

5、ning, when, while , at that time, just now 之类的短语一般用一般过去时。过去进行时可以用来代替一般过去时,表示更为偶然而非预定的动作I was talking to Tom the other day 那天我跟汤姆聊天来着。,典型的例子,1) Mary _ a dress when she cut her finger. A. made B. is making C. was making D. makes 答案C. 割伤手指是已发生的事情,应用过去时。同 时,when表时间的同时性,“玛丽在做衣服时“提供事情发生的背景,因此用过去进行时。,2) As

6、 she _ the newspaper, Granny _ asleep. read; was falling B. was reading; fell C. was reading; was falling D. read;fell 答案B.句中的as = when, while,意为“当之时“。描述一件事发生的背景时,用过去进行;一个长动作发生的时候,另一个短动作发生。句意为 “在她看报纸时,奶奶睡着了。“句中的 fell (fall的过去时),是系动词,后跟形容词,如:fall sick。,以when, while及as引导的时间状语从句 延续性动词:指动作可以延续一段时间,而不是瞬间

7、结束。 如:work、study、drink、eat等。 非延续性动词:指动作极为短暂,瞬间结束如:start、begin、jump、knock等。,1. 当从句中的谓语动词是 持续性的动作时, 用while, when或as 引导。,Eg:I was drawing the picture when my friend came. Jone was talking with his classmates when teacher called him.,当从句中的谓语动词表示瞬间动作时,不可用while。 Eg : He was on the point of leaving when so

8、meone knocked at the door. 如果谈论两个长动作,最常用的是while。,Eg:While John was sitting biting his nails,I was working out a plan to get us home.,如果表示两个短动作或事件 同时发生,常用as或just as, 也可用when。,Just as he caught the ball, there was a tearing sound 当他抓住球的时候,有一种撕裂的声音。,6. Tom burnt his hand when he _ the dinner. A. cooked

9、 B. was cooking C. has been cooking D. had cooked,注意:在上述所列的动词中,个别的也能用进行时态,但其词义发生了转变. I hear the girl singing. We are hearing a talk on the history of America. I have a computer. I am having lunch.,过去进行时与一般过去时的区别,过去进行时表示的动作在过去某个时间正在进行,可能完成,也可能没完成。,一般过去时表示动作或状态已经结束。,Mary _ a letter last night. 玛丽昨晚整晚都
