用所给动词的正确形式填空：Doyouknowwhatthey_____(do)thistimeyesterday?They_____(have)supperwhenwe_____(go)intotheroom.It______(rain)from7to9lastnight.Whenshe___(arrive)I___(telephone)Harry.What_____you___(do)yesterdayat7pm?WhenI______(go)downstairs(楼下),they_______(eat)breakfast.Ibrokeaglass,whileI_______(cook)thedinner.用when和while填空_____wewentout,itwassnowingheavily._____theywerewatchingthemovie,Joneleftthetheater.Shewaswearingabluedress___IsawHelen.____mymotherwassweepingthefloor,Ilefthome.Hewasreadinganewspaper_____hewaswaitingforabus.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：

Shewrotealettertoherfriendlastnight.

她昨晚给朋友写了封信。(信写完了)

Shewaswritingalettertoherfriendlastnight.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：

Shewavedtome.

她朝我挥了挥手。

Shewaswavingtome.

她一直朝我挥手。中考典型例题1.---Whydidn’tyougotoplayfootballwithusyesterdayafternoon?---I___mymotherwiththehouseworkthenhelpedB.washelpingC.hadhelpedD.havebeenhelping2.---AnnIcalledyouyesterdayevening,butnobodyansweredthephone.---Oh,I____awalkwithmymotheratthattime.A.takeB.tookC.amtakingD.waslisteningto

if引导虚拟语气的条件状语从句，从句为非真实条件句，一般用过去时(be的过去式用were)．主句用“should/would/could/might＋动词原形”.结构:典型试题1.Ifmyfather____herenow,he___tellmewhattodo.A.were,wouldB.were,stillC.had,willD.is,will2.IfI___(be)abird,I____(fly)inthesky.3.IfI___(find)apurse,I___(give)ittopolice.4.Ifyou___(have)somethingimportant,you___(cango)now.5.I___(help)youifIcould,butI’mafraidIcan’t.6.Ifyou___(lose),what__(will)youdo?PastperfectTense过去完成时一、概念过去完成时表示过去某一时间或某一动作之前已经发生的动作或状态，即过去的过去。图示如下：

过去完成过去现在将来二、构成：肯定句：主语+had＋过去分词否定句：主语+hadnot+过去分词疑问句：had+主语+过去分词…？Whenwegotthere,thefootballmatchhadalreadystarted.Hehadn’tworkedfortwoyearsbythen.Hadhefinishedtheworkbylastmonth?三、过去完成时的用法：过去完成时表示过去某一时刻或者某一动作之前完成的动作或状态;句中常用by,before,until,when等词引导的时间状语。e.g.Bythetimeshegotup,herbrotherhadalreadygoneintothebathroom.

(2)过去完成时的动词还可以表示过去某一时刻之前发生的动作或者状态持续到过去某个时间或者持续下去。例如：Beforeheslept,hehadworkedfor12hours.(3)在told,said,knew,heard,thought等动词后的宾语从句。例如：Shes
