仔细观察例句peoplewererunningwildlywhilepiecesofglassandbricksfallingdown 讨论并总结 当两个动词进行时 我们可以在两个分句中都用过去进行时 并用连接它们 b 再观察theearthquakestartedwhileiwasdoingsomeshopping iwastryingtofindmywayoutwhenisuddenlyheardsomenoiseaboveme 讨论总结 当一个动词还在进行时 又有别的事情发生 我们可以用或连接两个动作 我们用时态表示延续性动作 用时态表示短暂性动作 c 完成partb while whenandas都表示 当 的时候 e g iwassleepingwhentheearthquakestarted peoplewererunninginalldirectionswhilepiecesofglassandbrickswerefallingdown asiwastryingtofindmywayout isuddenlyheardsomenoiseaboveme usingwhile whenandas 1 当连接同时发生的两个延续性长动作时 常用while引导 e g whileiwaswatchingtv hewaslisteningtomusic milliewasreadingabookwhileeddiewassleeping 2 如果短暂性的动作是主句时 我们可以用when while或as引导 e g when while asmilliewaswatchingtv andycameintotheroom 3 如果延续性的动作是主句时 我们经常用when来连接 e g milliewaswatchingtvwhenandycameintotheroom 4 如果两个短暂性的动作同时发生 我们通常用as连接 e g asmilliesatdownonthesofa andycameintotheroom 注 当一个短暂性动作发生的同时伴随着一个延续性的动作 这时我们通常用过去进行时来表示延续性的动作 用一般过去时来表示短暂性的动作

强调过程 一般过去时表示一个已经完成的动作 表示动作发生过 而且已经结束了 强调结果 mary adresswhenshecutherfinger a madeb ismakingc wasmakingd makes wasmaking表示正在做衣服的过程 如用made则表示这一动作已结束 做衣服的动作已结束与cutherfinger就没有联系 2 he write aletter thenwenttobed wrote wrote表示动作已结束 做另一件事 如用waswriting就与wenttobed在逻辑上相矛盾 3 i msorryyoumissedthebus it leave 5minutesago 2006年徐州 left 4 mrjohn wefindyourwatch thankyou where find it 2006年绍兴 didyoufind 过去进行时与一般过去时的区别 2 1过去进行时侧重表示动作的延续 2一般过去时表示过去某时发生过某事 he allnightlastnight 生动的描写 他一直写 he somethinglastnight 说明他写了 的事实 waswriting wrote 注 下列几类动词通常不用于进行时 表示状态的动词be 感官动词 feel hear sound look smell taste等 表示思维或心理状态的动词 believe forget consider 认为 know remember hope wish want等 表示所属关系的动词 belong have own hold 容纳 等 1 i myhomeworkwhenmike lastnight 昨天晚上迈克来的时候我正在写作业 2 whileann tv herfather home 安正在看电视时 她父亲回来了
