初中过去进行时讲解练习和答案解析

过去进行时的讲与练过去进行时表示过去某一时刻或者某段时间正在进行或发生的动作，常和表过去的时间状语连用，如：i was doing my homework at this time yesterday.昨天的这个时候我正在做作业。they were waiting for you yesterday.他们昨天一直在等你。过去进行时的构成：肯定形式：主语+was/were+v-ing否定形式：主语+was not (wasnt)/were not (werent)+v-ing疑问形式： was/were+主语 +v-ing 。基本用法：1. 过去进行时表示过去某一段时间或某一时刻正在进行的动作。常与之连用的时间状语有，at that time/moment, (at) this time yesterday (last night/sunday/week), at+ 点 钟 +yesterday (last night / sunday)， when sb. did sth等时间状语从句，如：what were you doing at 7p.m. yesterday?昨天晚上七点你在干什么？i first met mary three years ago. she was working at a radio shop at the time.我第一次遇到玛丽是在三年前，当时她在一家无线电商店工作。i was cooking when she knocked at the door.她敲门时我正在做饭。2. when后通常用表示暂短性动词，while 后通常用表示持续性动词，因此它所引导的状语从句中，谓语动词常用进行时态，如：when the car exploded i was walking past it.= while i was walking past the car it exploded.3. 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。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，这时下起雨来了一般过去时与过去进行时的用法比较：一般过去时表示“在过去某个时间发生的动作或存在的状态”，而过去进行时则表示“在过去某个特定时间正在进行的动作”。如： tom wrote a letter to his friend last night.汤姆昨晚给他的朋友写了封信。（信写完了）tom was writing a letter to his friend last night.汤姆昨晚一直在给他的朋友写信。（信不一定写完，只是强调了动作的延续性）。过去进行时和一般过去时的差别：一般过去时表示“在过去某个时间发生的动作或存在的状态”，而过去进行时则表示“在过去某个特定时间正在进行的动作”。例如：i was reading an english novel last night.昨晚我在看一本英文小说。（可能没看完）i read an english novel last night我昨晚看了一本英文小说。（已经看完）过去进行时练习1. while we (wait) for the bus, a girl (run) up to us.2. i (telephone) a friend when bob (come) in.3. jim (jump) on the bus as it (move) away.4. we (test) the new machine when the electricity (go) off.5. she (not want) to stay in bed while the others (all, work) in the fields.6. while mother (put) cathy to bed, the door bell (ring).7. as i (walk) in the park, it (begin) to rain.8. even when she (be) a child she (already, think) of becoming a ballerina ( 芭蕾舞演员 ).9. it was quite late at night. george (read) and amy (play) her needle whenthey (hear) a knock at the door.10. there (be) a group round the fire when they (reach) it. an old woman (sit)onthegroundnearthekettle;two smallchildren (lie)nearher;a donkey (bend) his head over a tall girl.1. i (have) my breakfast at half past six yesterday morning.2. mary (go) over her lessons from six to seven last night. john and peter (do) the same thing.3. what you (do) at that time?we (watch) tv.4. was your father at home yesterday evening? yes ,he was. he (listen) to the radio.5. they (not make) a model ship when i saw him.6. they (have) a meeting at 4 yesterday afternoon? no, they . they (clean) the classroom.7. it (rain) when you left school?yes, it .
