外研八下英语Unit 1 Presenting ideas-Reflection《单元语法沙龙》课件

单元语法沙龙观察下列句子，圈出谓语部分，总结一下谓语部分的共同点1.TeaisgrownbypeopleinHangzhou.2.Thekitewasmadebyhim.3.Thetaskwillbefinishedbytheminanhour.4.Theymaysoonbereplacedbymachines.5.Itwillbegreatlyneeded.________________________________________________________共同点：谓语部分都是被动语态，被动语态由be+过去分词组成被动语态（1）英语中有两种语态，即主动语态和被动语态。当主语为动作的执行者或发出者时，要用主动语态；当主语为动作的承受者时，要用被动语态。考点1主动语态变被动语态的方法（1）主动语态中的O（宾语）变成被动语态中的S（主语），主动语态中的谓语动词变成被动语态中的be动词+done(动词的过去分词)，时态要保持一致。（2）主动语态中的S（主语）变成被动语态中的O（宾语）时，要添加by。主动句：They

plant

atreeeveryyear.主语谓语动词宾语被动句：Atree

isplantedbythemeveryyear.记忆口诀主动句变被动句宾变主，主变宾，by短语后面跟；谓语动词变被动，be后“过分”来使用。考点2被动语态的用法（1）需强调或突出动作的承受者；不知道或没必要指出动作的执行者是谁。·RiceisgrowninthesouthofChina.中国南方种水稻。·Thishousewasbuiltin1901.这座房子是在1901年建的。（2）需强调或突出动作的执行者。·Chineseisspokenbymoreandmorepeopleintheworld.世界上越来越多的人说汉语。·Theteacherisrespectedbyallofhisstudents.这位老师受到他所有学生的尊敬。（3）正式文体或客观陈述。·Smokingisnotallowedhere.这里不允许吸烟。考点3一般现在时的被动语态分类句式肯定句主语+be(am/is/are)+过去分词(+by+动作执行者).否定句主语+be(am/is/are)+not+过去分词(+by+动作执行者).一般疑问句Be(Am/Is/Are)+主语+过去分词(+by+动作执行者)?特殊疑问句特殊疑问词+be(am/is/are)+主语+过去分词（+by+动作执行者）?·Footballisplayedbypeopleinmostcountriesintheworld.世界上大多数国家的人都踢足球。·Thebabyisnotlookedafterbyhisfather.这个婴儿不是由他父亲照顾的。·IsKingLearwrittenbyShakespeare?《李尔王》是莎士比亚写的吗？·Whereisthedeskmade?这张桌子是在哪儿制造的？考点4一般将来时的被动语态分类句式肯定句主语+will/be(am/is/are)goingto+be+过去分词(+by+动作执行者).否定句主语+willnot/be(am/is/are)notgoingto+be+过去分词(+by+动作执行者).一般疑问句Will/+主语+be+过去分词(+by+动作执行者)?Be(Am/Is/Are)+主语+goingto+be+过去分词(+by+动作执行者)?分类句式特殊疑问句特殊疑问词+will+主语+be+过去分词(+by+动作执行者)?特殊疑问词+be(am/is/are)+主语+goingto+be+过去分词(+by+动作执行者)?·Anewstadiumwillbeputuphere.一个新的体育场将在这里建造。·Anewstadiumwillnot/won’tbeputuphere.一个新的体育场将不会在这里建造。·—Willanewstadiumbeputuphere?一个新的体育场会在这里建造吗？—Yes,itwill./No,itwon’t.是的，会。/不，不会。·Wherewillanewstadiumbeputup?一个新的体育场会在哪里建造？一单项选择1.[江苏扬州中考]Asweallknow,theYangtzeRiver_______asa“motherriver”oftheChinesenation.A.knowsB.knewC.isknownD.wasknown2.—TherehasbeenlessandlesspollutioninLeshantheseyears.—Thegovernmenthasmadeagreateffortonit.I’msurethisproblem_______onedayinthefuture.A.wassolvedB.solvesC.willbesolvedD.willsolveCC3.[北京中考]Languagelearningapps_______bymoreandmorepeoplethesedays.A.useB.usedC.areusedD.wereused4.Adance_______inthathalltoraisemoneyforcharitynextSunday.A.holdB.areheldC.willholdD.willbeheld5.[北京东城区二模]Smartrobots_______bymoreandmorepeoplearoundtheworldinthefuture.A.useB.willuseC.areusedD.willbeusedCDD二用被动语态完成句子6.Mymummakesmedothedisheseveryday.Iam__________________dothedishesbymymumeveryday.7.Thebeescollecthoneyfromtheflowers.Honey__________________fromtheflowersbythebees.8.Theywillfinishtheworkintenminutes.Thework__________________________bythemintenminutes.madetoiscollectedwillbefinished9.WewillholdaclassmeetingtotalkaboutteamworknextFriday.Aclassmeetingwill__________________byustotalkaboutteamworknextFriday.10.Studentsshouldfollowrulesatschool.Rulesshould__________________bystudentsatschool.beheldbefollowed三短文填空（语篇练语法）AI11._________(be)widelyusedinmanyfieldsandbringsalotofbenefits.HomeDoctor12._____________(invent)bythreemiddleschoolstudentsthreemonthsago.Itlookslikealovelygirl.Withthehelpofrobots,theelderly13._____________(take)goodcareofinthefuture.iswasinventedwillbetakenInthefuture,we14._____________________(notneed)manyteachersanymore
