被动语态复习PPT课件

.,1,被动语态复习,.,2,被动语态的构成。被动语态由“助动词be及物动词的过去分词”构成。人称、数和时态的变化是通过be的变化表现出来的。常用时态的被动语态的构成：一般现在时：am/is/are+过去分词如：Theflowersarewateredeveryday.一般过去时：was/were+过去分词如：Thehousewasbuiltbytheworkerslastyear.现在进行时：am/is/are+being+过去分词如：Hisfatherisbeingsenttothehospital.,.,3,现在完成时：have/has+been+过去分词如：Theworkhasbeenfinishedbythem.一般将来时:will/shall+be+过去分词如：Thebridgewillbebuiltintwomonths.含情态动词的句子：can/must等+be+过去分词如：Canyourhomeworkbehandedinsoon?,.,4,主动语态变被动语态的方法。主动语态的句子变被动语态的步骤：1.句子的主语变为宾语，前面加by（主语是人称代词时须变为宾格）。2.句子的宾语变为主语。3.谓语动词的主动形式变为被动形式（时态保持不变）。例如：Hecleanshisbedroomeveryday.Hisbedroomiscleanedbyhimeveryday.例如：HecanspeakFrenchattheageoffive.Frenchcanbespokenbyhimattheageoffive.,.,5,被动语态的特殊情况。1.动词不定式在使役性动词“make，let”等及感官动词“hear,watch,see,”等动词后作宾语补足语时，常省略。但变为被动语态时，后面要跟带的动词不定式。例如：MothermakesTomdosomehouseworkeveryday.（变被动语态）误：Tomismadedosomehouseworkeveryday.正：Tomismadetodosomehouseworkeveryday.,.,6,2.实义动词need的被动语态不是is/are+needed或need+be+过去分词，而是need+to+be+done或need+doing例如：Heneedstorepairhishouse.（变被动语态）误：Hishouseisneededtorepairbyhim.误：Hishouseneedsberepairedbyhim.正：Hishouseneedstoberepairedbyhim.正：Hishouseneedsrepairingbyhim.,.,7,被动语态跟踪练习题一、根据句意，用所给动词的适当形式填空。1.Football(play)byTomyesterday.2.Aletter(write)tohispenfriendbyhimnow.3.Theworkers(make)(work)morethantenhourseveryday.4.Theclassroom(clean)byJackonWednesday.,.,8,wasplayed2.isbeingwritten3.aremade,towork4.iscleaned,.,9,5.Thatfilm(see)twicebyus.6.Sometrees(plant)bythestudentsnextweek.7.LiLeioften(hear)(sing)Englishsongs.8.Theirhomework(can,finish)ontime.,.,10,5.hasbeenseen6.willbeplanted7.is,heard,tosing8.canbefinished,.,11,句型转换：1.LastSundayweheardthemsingPekingOperainthattheatre.(改为被动语态)TheywereheardPeakingOperainthattheaterlastSunday.2.Wecleanourclassroomtwiceaday.(改为被动语态)Ourclassroomtwiceaday.3.PeoplegrowcottoninNorthChina.(改为被动语态)CottoninNorthChina.,.,12,1.to;sing2.is;cleaned3.is;grown,.,13,4.DidshetakethepicturesneartheDamingLakewhentheguideshowedheraroundthe“SpringCity”?(改为被动语态)thepicturesneartheDamingLakewhenaroundthe“SpringCity”.5.PeoplegrowriceinthesouthofChina.(改为被动语态)RiceinthesouthofChina.,.,14,4.Were;taken;she;wasshown5.is;grown,.,15,1.Oneortwoman-madesatellites_inourcountryeveryyear.A.havebeensentupB.willbesentupC.issentupD.aresentup2.Mr.Li,you_onthephone.A.arewantedB.werewantedC.arebeingwantedD.willbewanted3.Foodandclothes_bywomen.AisoftentalkaboutB.areoftentalkedC.areoftentalkedaboutD.oftentalkedabout,.,16,4.Thebaby_whenMotherisout.A.welllookedafterB.waslookedwellC.iswelllooked
