Unit3SectionB(1a-1d)课件八年级英语上册

初中英语鲁教版八上Unit3Whatwereyoudoingwhentherainstormcame?SectionB(1a-1d)1.基本概念过去进行时表示在过去某一时刻或一段时间内正在进行的动作。这一特定的过去时间除有上下文暗示以外,一般用表示过去的时间状语来表示。2.结构was/were+动词-ing形式复习过去进行时的用法Revision3.句式(以work为例)肯定式:

I/He/She/Itwasworking.We/You/Theywereworking.否定式:I/He/She/Itwasnotworking.We/You/Theywerenotworking.疑问式和简略回答:WasIworking?Yes,youwere./No,youwerenot.Wereyouworking?Yes,Iwas./No,Iwasnot.Washe/she/itworking?Yes,he/she/itwas./No,he/she/itwasnot.Werewe/you/theyworking?Yes,you/we/theywere./No,you/we/theywerenot.复习过去进行时的用法Revision1.wasnot常缩略为wasn’t;werenot常缩略为weren’t。2.一般过去时与过去进行时用法的比较:一般过去时表示在过去某个时间发生过的动作或存在的状态,而过去进行时则表示在过去某一时刻或某一段时间正在进行的动作。e.g.Davidwrotealettertohisfriendlastnight.戴维昨晚给他的朋友写了封信。(信写完了。)Davidwaswritingalettertohisfriendlastnight.戴维大卫昨晚在给他的朋友写信。(信不一定写完。)Revision学习过去进行时需要注意的问题这两个词都有“当……的时候”的意思。when既可指某一点时间,也可以指一段时间;while

强调一段时间,所以从句的谓语动词常是延续性的。当when表示“在某一段时间里”的意思时,它可以代替while,但while不能代替when。e.g.WhenIcamehome,shewascookingdinner.

当我到家时,她正在做饭。

Whenyouhangwetclothesnearafire,youwillseesteamrisingfromthem.当你把湿衣服挂在火边时,你会看到水汽从衣服上升起。过去进行时中when与while的用法Revision1.realize理解；领会；认识到2.makeone’sway前往；费力地前进3.passage章节；段落4.pupil学生5.completely彻底地；完全地6.shocked惊愕的；受震惊的7.silence沉默；缄默；无声8.insilence沉默；无声9.recently不久前；最近10.takedown拆除；往下拽；记录11.terrorist恐怖主义者；恐怖分子12.date日期；日子13.tower塔；塔楼14.atfirst首先；最初15.truth实情；事实16.Allen艾伦（姓）17.MartinLutherKing马丁‧路德‧金18.Alabama阿拉巴马州19.AnimalHelpline动物保护热线19.WorldTradeCenter世贸大楼Learnthenewwordsandexpressions.NewwordsThinkofatimewhenyouwerelatefororcouldn’tgotoanevent.Whatwastheevent?Whatwasthereasonwhyyouwerelateorcouldn’tgo?Tellyourpartnerthestory._______________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________1aWhateventhappenedattheschoolyesterday?___________________________________________________2.Whomissedtheevent?___________________________________________________3.Whichteamwonattheevent?___________________________________________________Therewasabasketballcompetition.Katemissedtheevent.John’steam.Listenandwriteshortanswerstothequestions.1bJohn:Hey,Kate,whyweren’tyouattheschoolbasketballcompetitionyesterday?Icalledyousomanytimes,butyoudidn’tanswer.Kate:Sorry,John.Ileftmyphoneathome.John:Whatwereyoudoingatthetimeofthecompetition?Kate:Well,Ileftmyhouselateandwhenthecompetitionstarted,Iwasstillmakingmywaytoschool.John:Thenwhathappened?Kate:WhenIgottothebusstop,Irealizedthatmybagwasstillathome!TapescriptsJohn:Butwhydidn’tyoujustgohometogetyourbag?Kate:Idid,butwhileIwasrunningbackhome,Isawadogbythesideoftheroadanditwashurt.John:Oh,soI’msureyouhelpedthedog.Iknowhowmuchyouloveanimals.Kate:Yes,IwantedtocalltheAnimalHelpline,butIdidn’thavemyphonesoIhadtowaitforsomeonetowalkby.ThenIusedhisphonetocallthehelpline.John:OK.Nowonderyoudidn’tmakeittothecompetition.Kate:Yes,I’msosorryIwasn’ttheretocheeryouon,butI’mhappythatyourteamwon!TapescriptsChooseonetobegin!LastWednesday,Iwaslateforschool.When/While…LastSaturday,Icouldn’tgotomyfriend’sbirthdayparty.When/While…
