被动语态复习教案九、被动语态总第课时Step1.学生自学被动语态的用法1.一般现在时的被动语态构成：is/am/are+及物动词的过去分词Ourclassroomiscleanedeveryday.Iamaskedtostudyhard.2.一般过去时的被动语态构成：was/were+及物动词的过去分词Anewshopwasbuiltlastyear.3.现在完成时的被动语态构成：has/have+been+及物动词的过去分词Manyman-madesatelliteshavebeensentupintospacebymanycountries.4.一般将来时的被动语态构成：will+be+及物动词的过去分词Anewhospitalwillbebuiltinourcity.5.含有情态动词的被动语态构成：情态动词+be+及物动词的过去分词Youngtreesmustbewateredoften.Yourhomeworkcanbehandedintomorrow.6.现在进行时的被动语态构成：am/is/are+being+及物动词的过去分词UncleWangismendingmybikenow.→MybikeisbeingrepairedbyTomnow.7.不定式的被动语态：to+be+及物动词的过去分词Therearetwobookstoberead.→Therearetwentymoretreestobeplanted.Step2.教师点拨使用被动语态的注意问题1.有些动词用主动形式表示被动意义。Thispenwriteswell.Thisnewbooksellswell.2.感官动词或使役动词使用省略to的动词不定式，主动语态中不带to，但变为被动语态时，须加上to。例：makesomebodydosomething→somebody+be+madetodosomethingseesomebodydosomething→somebody+be+seentodosomethingAgirlsawmywalletdropwhenshepassedby.→Mywalletwasseentodropbyagirlwhenshepassedby.Thebossmadethelittleboydoheavywork.→Thelittleboywasmadetodoheavyworkbytheboss.3.如果是接双宾语的动词改为被动语态时，直接宾语(物)作主语，那么动词后要用介词，这个介词是由与其搭配的动词决定。Hegavemeabook.→Abookwasgiventomebyhim.Heshowedmeaticket.→Aticketwasshowntomebyhim.Myfatherboughtmeanewbike.→Anewbikewasboughtformebymyfather.4.一些动词短语用于被动语态时，动词短语应当看作一个整体，而不能丢掉其中的介词或副词。Helistenstotheradioeveryday.→Theradioislistenedtobyhimeveryday.Thenurseistakingcareofthesickman.→Thesickmanisbeingtakencareofbythenurse.Step3.巩固练习选择填空:1.Thereadingroom________yesterdayafternoon.A.cleanedB.iscleanedC.wascleaningD.wascleaned2.Theworkersweremade________tenhoursaday.A.workB.toworkC.workingD.worked3.Food________inacoolplaceinsummer.A.mustkeepB.mustn’tkeepC.mustbekeptD.mustn’tbekept4.Hisfather________toworkinHongKong3yearsago.A.sentB.wassentC.hassentD.hasbeensent5.Thepen________well.A.writesB.iswrittenC.waswrittenD.writing6.Greatchanges________inthetownsince1988.A.havetakenplaceB.havebeentakenplaceC.hastakenplaceD.hasbeentakenplace7.Ourcompositionsmust________nextMonday.A.behandinB.behandedinC.handedinD.behandingin8.Thechildwill________backtohisparentsnextmonth.A.sentB.sendC.besentD.besending9.________hiswork________yet?A.have…beenfinishedB.has…beenfinishedC.has…finishedD.have…finished10.Theclassroom________nowA.iscleaningB.isbeingcleaningC.isbeingcleanedD.iscleaned教学反思
