was/werebeingdoneTreeswerebeingplantedbythematthistimeyesterday.昨天这个时候他们正在植树。二、过去进行时态的被动语态的基本结构1肯定式：主语+was/were+beingdone+其他.AnotherbridgewasbeingbuiltovertheYangtzeRiverthen.那时长江上正在修建另一座桥。2否定式：主语+was/were+not+beingdoneShelookedbehindtomakesureshewasnotbeingfollowed.她往后看了看确保没有被人跟踪。3一般疑问句：Was/Were+主语+beingdone+其他?Wasanewlibrarybeingputupintheirschooljustthen?他的学校当时正在建一栋新楼吗？4特殊疑问句:特殊疑问词+was/were+主语+beingdone+其他?Howwasthebuildingbeingbuiltlastyearthistime?这座大楼去年这时候是怎么建造的？三、过去进行时态的被动语态的用法1过去进行时态的被动语态同它的主动语态一样，表示过去正在进行的被动动作。Hewasbeinginterviewedbyourheadmasterwhenwecamein.我们进来时，他正在接受校长的面试。Thisfilmwasbeingshownatthistimeyesterday.这部电影昨天这个时候正在上映。2过去进行时态的被动语态一般不与表示一段时间的状语或表示次数的状语连用，要使用完成时态的被动语态。Thewatchwasbeingrepairedtwice.×Thewatchhasbeenrepairedtwice.√这块表已经修过两次了。四、过去进行时态的被动语态与一般过去时的被动语态的区别过去进行时态的被动语态强调的是在过去的某个时间点正在进行的被动动作，而一般过去时的被动语态表示的是某个被动的动作在过去发生了。e.g.Theresearchwasbeingdonewhentheprofessorwentintothelablastnight.昨晚教授走进实验室时，研究正在进行。Somecomputerswerestolenlastnight.昨晚有些电脑被偷了。2Rewritethepassageusingthepastcontinuouspassive.Walkinghomeafewdaysago,Isawthatpeopleweredoingreconstructionworkontheoldmarket.Itwouldbeturnedintomodernshoppingmall.Somepeopleweretearingdowntheoldgate.Somewereremovingthewoodenstands.Somewereclearingawayrubbishfromthefloor.Whileallthisgoingon,ajournalistwastakingphotos.Theresultingstoryinthelocalnewspaperdividedthepeopleofthetown:somewereinfavourofthenewshoppingmall,andsomewereagainstit.Answer:Walkinghomeafewdaysago,Isawthatreconstructionworkwasbeingdoneontheoldmarket.Itwouldbeturnedintoamodernshoppingmall.Theoldgatewasbeingtorndown.Thewoodenstandswerebeingremoved.Rubbishwasbeingclearedawayfromthefloor.Whileallthiswasgoingon,photoswerebeingtakenbyajournalist.Theresultingstoryinthelocalnewspaperdividedthepeopleofthetown:somewereinfavourofthenewshoppingmall,andsomewereagainstit.3Lookatthetwogroupsofpicturesanddescribethechangesinthenewsindustryusingthepastcontinuouspassivewhereappropriate.Yesterday,Iwatchedadocumentaryaboutthenewsindustryinthepast.Isawthataninterviewwasbeingdonefacetoface.Butnow,interviewscanbedoneonline...Sample:Yesterday,Iwatchedadocumentaryaboutthenewsindustryinthepast.Isawthataninterviewwasbeingdonefacetoface.Butnow,interviewscanbedoneonline.Newswasbeingeditedwithapenwhileitcannowbeeditedonacomputer.NewswasbeingprintedonpaperwhileitcannowbereleasedontheInternet.Newspaperswerebeingdeliveredtoreaders’doors,whereasnewscannow
