过去进行时的固定句型。1)根据汉语意思翻译下列句子。①当发生地震时，我正在购物。I_____________someshoppingwhenit__________.②当玻璃、瓦片往下掉的时候，人们正慌乱地跑着。People________________wildlywhilepiecesofglassandbricks________________down.③我正在寻找出路时，突然我听到头顶上有声音。I________________tofindmywayoutwhenIsuddenly________Somenoiseaboveme.2)讨论：有时为了句子表达的需要，我们可以用复合句来表达过去进行时，如以上3句。3)在过去进行时中when

和while用法及其区别。①昨晚当我到家的时候，妈妈和爸爸正在看电视。Myparents_________(watch)TVwhenIarrivedhomelastnight.②刚才当老师走进教室的时候，学生们正在读书。Students____________(read)whentheteachercameinjustnow.总结：1.在这些句子中，when引导的句子表示过去的某一个具体的时间，when从句用一般过去时，而它的主句用过去进行时。2.但是若强调某个动作正在进行中时，又发生了别的动作，用when从句。when从句必用过去进行时，主句用一般过去时。若表示在when从句正进行期间又发生了主句的动作，此时，when=while,表时间段。.__________wewerehavingsupper,thelightwentout.____________hewasridingabike,hefelloffandhurthisleg.3.若主、从句两个延续动作同时进行，用while，则主句与从句都用进行时，此时，while译为“而”“一边，一边”。.Hewasreadingthenewspaper__________Iwasstudying.【当堂检测】单项选择题()1.MybrotherhisbookintheclassroomwhenIcamein.A.readB.readsC.wasreadingD.isreading()2.--Iphonedyoulastnightbutnooneanswered．--Sorry,Itomusic．A.1istenB.1istenedC.waslisteningD.havelistened()3.WhenIwenttosaygoodbyetoAnna,shethepianoA.isplayingB.playsC.wasplayingD.played．()4.--Whatdoyouthinkofthecolourofmynewdress?--Sorry,butwhatdidyousay?Iaboutsomethingelse.(2023年扬州市)|A.thinkB.thoughtC.amthinkingD.wasthinking()5.Timmywasdoingsomeshoppingwhentheearthquake.A.startedB.wouldstartedC.wouldstartD.wasstarting()6.MykeysarenotinmypocketImustforgetthe.A.takeB.takingC.tookD.totake()7.Don’t1etthestudents____allthetime.TelIthem__arestsometimes.A.study;haveB.study;tohaveC.tostudy;havingD.tostudy;tohave2.用所给动词的适当形式填空1)NowJim’ssister__________________(read)newspapers.2)He__________________(watch)TVatninelastnight.3)He_________(watch)TVlastnight.4)What_________thetwins____(do)then?5).------________Lily_________(draw)acatwhentheteachercamein?------No,she_________.6)
