昨天早上7點你在做什么？—Iwashavingbreakfast.我在吃早餐。過去進行時過去進行時除了表示"過去某時刻/時段在做某事"之外，還常常出現(xiàn)在講故事的語境中。Alicewassittingwithhersisterbytheriver.艾麗斯正和姐姐坐在河邊。Theywerehavingateapartyinthegarden.他們正在花園里舉行茶會。過去進行時的結(jié)構(gòu)肯定句ShewassingingwhenIenteredtheroom.我進房間時，她正在唱歌。Theywerearguingaboutthemovielastnight.昨晚他們一直在爭論那部電影。主語+was/were+現(xiàn)在分詞（-ing）+其他.過去進行時的結(jié)構(gòu)否定句Hewasn'tpayingattentionduringthemeeting.開會時他根本沒在聽。Weweren'tjoking—thisisserious!我們沒開玩笑，這是認真的！主語+was/were+not+現(xiàn)在分詞（-ing）+其他.過去進行時的結(jié)構(gòu)一般疑問句1)WereyoustilldoingyourhomeworkwhenIcalledyoulastnight?2)Wasthebabycryingloudlywhentheearthquakestarted?Was/Were+主語+現(xiàn)在分詞（-ing）+其他?過去進行時的結(jié)構(gòu)特殊疑問句1)Whatwereyoudoingat10AMyesterday?2)Whywasshecryinginthehallway?疑問詞(What/Where/Why等)+was/were+主語+現(xiàn)在分詞(-ing)?如何區(qū)別并準確使用過去進行時和一般過去時呢？1)Laurawasreadinganovelateighto'clocklastnight.2)Laurareadanovellastnight.昨晚8點Laura在看小說。昨晚Laura看了一本小說。過去進行時和一般過去時雖然都表示過去發(fā)生的事情，但是過去進行時強調(diào)過去某一時刻或時段正在進行或持續(xù)的動作；一般過去時表示過去的時間里所發(fā)生的動作，所表示的動作往往已經(jīng)完成。1)Oneday,whenHenrywasworkinginarestaurant,asnakesuddenlyappeared.2)Whilepeoplewerewaitingforthetrafficlights,acarsuddenlyappearedroundthecorner.3)Asthedoctorswerecheckinghim,thepaingotworse.

過去進行時還可以和when,while,as引導的表示過去的時間狀語從句連用，形成復合句。when和while引導的從句與過去進行時連用的幾種情況:when引導的時間狀語既可以指時間點，也可以指時間段，

動詞可以是終止性動詞，也可以是延續(xù)性動詞；while引導

的時間狀語只指時間段，動詞必須是延續(xù)性動詞。Theyarrivedwhilewewerehavingdinner.=Theyarrivedwhenwewerehavingdinner.由when引導的時間狀語從句，如果主句用過去進行時、從句

用一般過去時，則表示一個動作正在進行的時候另一個動作

(突然)發(fā)生了，強調(diào)后一動作發(fā)生的突然性。Weweretalkingwhentheteachercamein.Whileweweretalking,theteachercamein.(只表明老師進來的事實，不強調(diào)突然性)當主句和從句的動作都是延續(xù)的或同時發(fā)生的，

兩句都用過去進行時的時候多用while引導。Theyweresingingwhileweweredancing.WhileIwascooking,mybrotherwassettingthetable.6Completethesentenceswiththecorrectformoftheverbsinbrackets.1People___________________(sleep)whenthevolcanoerupted.2Whilethey___________________(walk)alongtheriver,agreatstormbrokeout.3Whilethehurricane__________________(blow)heavily,airlinescouldnotflyinthearea.4Thefire___________________(spread)quicklyand______________(cover)thebuildingwhenIheardavoice.weresleepingwerewalkingwasblowingwasspreadingcovering7Completethepassagewiththecorrectformoftheverbsinbrackets.Atfirst,itwasjustanothernormalweekday.I1________________(wait)attherailwaystationwhenI2________________(hear)anotice:therewasaheavyrainstorm,soalltrainserviceswerestopped.waswaitingheard7Completethepassagewiththecorrectformoftheverbsinbrackets.Whileothers3_________________(call)theirfamiliesorsearchingfornewsreports,Igotmoreandmoreworried.Ihadalongjourneytomake.Astimewentby,people4______________(become)louderandangrier.Justthen,alovelymusics5_______________(start).werecallingbecamestarted7Completethepassagewiththecorrectformoftheverbsinbrackets.Themusicof"MeandMyMotherland"6__________(stop)allthenoises.Manytravellers7___________(sing)alongwiththemusic.Onewomanstartedtocrywhileshe8________________(listen).Thatwonderfulmusicwasfromastudentorchestra.Itliftedourspiritandgaveushope.stoppedsangwaslistening8Tellastoryaboutanaturaldisaster.UsethewordsandexpressionsfromthereadingpassageandtheUsefulexpressionstohelpyou.?Itwasaterrible...?Peoplewere...?A(n)...happenedin...?Thecauseof...was...?Thebuildings/roads/trees/animalswere...?...peoplelosttheirlives.?...peoplewereinfluencedand...homeswerebroken.ExampleWhatwasthedisaster?Whendidithappen?Wheredidithappen?Whowasthere?Howdiditdevelop?Whatdidpeopledo?Howdidpeoplefeel?Whathappenedafterthedisaster?SampleTheTerribleEarthquakeItwasaterribleearthquakethathappenedinasmallcoastaltownlastsummer.Thedisasterstruckatmidnightwhenmostpeopleweresleeping.Thegroundshookviolently,andbuildingscollapsedwithinseconds.Roadswerecracked,treeswereuprooted,andanimalsranwildlyinfear.Thecauseoftheearthquakewasasuddenshiftintectonicplatesdeepunderground.Thousandsofpeoplelosttheirlives,andmanymorewereinjured.Survivorsrushedoutoftheirhomes,screamingandcrying.Peoplewereterrified,clutchingtheirlovedonesasaftershockscontinued.Sometriedtocallforhelp,whileotherssearchedformissingfamilymembersintherubble.Afterthedisaster,thetownwasunrecognizable.Houseswerereducedtopilesofbrokenwoodandconcrete.Rescueteamsarrivedquickly,butthedamagewastoosevere.Thousandsofpeoplewereinfluenced,andcountlesshomeswerebroken.Forweeks,survivorslivedintemporaryshelters,hopingtorebuildtheirlives.Theearthquakeleftdeepscars,butthecommunitycametogethertosupportoneanother.Thoughthedisasterwasdevastating,itshowedthestrengthofhumancourageandkindness.Languagepoints1.Whiletheywerewalkingalongtheriver,agreatstormbrokeout.
