Unit9,Whenwasitinvented?,英语中的动词有两种语态：主动语态(TheActiveVoice)和被动语态(ThePassiveVoice)。主动语态中，主语是谓语动作的执行者，被动语态中，主语是谓语动作的承受者。被动语态的构成：be+及物动词的过去分词,被动语态(ThePassiveVoice),1.被动语态定义被动语态表示主语是动作的承受者。如：ThetelephonewasinventedbyBellin1876.,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。助动词be有人称、数和时态的变化，其变化规则与be作为连系动词时完全一样。如：(1).Itwasinventedin1876.(2)Theyareusedforlisteningtomusic.,3.被动语态的用法当我们不知道谁是动作的执行者或者没有必要指出谁是动作的执行者，或者只须强调动作的承受者时，要用被动语态，如：EnglishisspokeninCanada,Grammar:Thepassivevoice(被动语态）,一般现在时am/is/are+p.p一般过去时was/were+p.p一般将来时shall/will+be+p.p过去将来时would/should+be+p.p现在进行时am/is/are+being+p.p过去进行时was/were+being+p.p现在完成时have/has+been+p.p过去完成时had+been+p.p含有情态动词的被动语态：can/may/mustbe+p.p,主动句变被动句的方式：主动句：主语+及物动词谓语+宾语被动句：主语+be+过去分词+by宾语Ourteacherlovesherstudents.Herstudentsarelovedbyourteacher.,请把下列主动句变为被动句:Theyproducedthatkindofcar.Theworkersbuiltabridgeovertheriver.Mothertellsmeastoryeveryday.,Thatkindofcarwasproducedbythem.,Abridgewasbuiltbytheworkersovertheriver.,IamtoldastorybyMothereveryday.,用所给动词的正确形式填空：,1)Thebike_(fix)upbyXiaoMingyesterday.2)Sunglasses_(use)forprotectingpeopleseyes.3)Apicture_(put)upontheblackboard.4)French_(speak)inFrance.5)Teenagersshould_(allow)tochoosetheirownclothes.,wasfixed,areused,isput,isspoken,beallowed,动词填空：TheTV_(invent)around1927.Theyareusedfor_(see)inthepark.Thiskite_(make)byUncleWang.Tea_(discover)alongtimeago.Ourclassroom_(shouldclean)everyday.,wasinvented,seeing,wasmade,wasdiscovered,shouldbecleaned,句型转换1.Peopleallovertheworldenjoysurfing.(同义句转换)Surfing_bypeopleallovertheworld.2.Whenhewasthirty,TomdecidedtomovetoLondon.(同义句转换）Atthe_ofthirty,Tommadea_tomovetoLondon.3.Katetookgoodcareofthebabyyesterdayevening.(改为被动句）Thebaby_byKateyesterdayevening.4.Shewasseentocomeoutofthelibrarybyhim.(改为主动句)He_outofthelibrary.5.TheLeaguewasfoundedinGuangzhouin1922.(对画线部分提问)_theLeague_?,isenjoyed,age,decision,wastakengoodcareof,sawhercome,Whenandwherewas,founded,6.Didyouseethefilmlastnight?(改为被动句)_thefilm_byyoulastnight?7.LiLeigaveTomanewpenlastweek.(改为被动句)Anewpen_Tomlastweek.8.Hedidntgotobedbeforehefinishedhiswork.(同义句转换)He_gotobed_hefinishedhiswork.9.Theyareusedforseeinginthedark.(对画线部分提问)_aretheyused_?10.Ithinkthemosthelpfulinventionisthelightbulb.(对画线部分提问)_doyouthink_themosthelpfulinvention?,Was,seen,wasgivento,didnot,until,What,for,What,is,11.Hisfatherboughtacomputerforhimlastmonth.(改为被动句)Acomputer_forhimlastmonth.12.Englishiswidelyspokenintheworld.(改为主动句)People_English_intheworld.13.Itwasinventedin1888.(对画线部分提问)_wasit_?,wasbought,speak,widely,When,invented,invented,crispy,pleasant,accident,microwave,inventions,invented,produced,mistakes,leaves,()1._anewlibrary_inourschoollastyear?A.Is;builtB.Was;builtC.Does;buildD.Did;build()2.Anaccident_onthisroadlastweek.hasbeenhappenedB.washappenedC.ishappenedD.happened()3.Cotton（棉花）_inthesoutheastofChina.A.isgrownB.aregrownC.growsD.grow()4.Sofar,themoon_bymanalready.isvisitedB.willbevisitedC.hasbeenvisitedD.wasvisited()5.AtalkonChinesehistory_intheschoolhallnextweek.A.isgivenB.hasbeengivenC.willbegivenD.gives()6.Howmanytrees_thisyear?A.areplantedB.willbeplantedC.havebeenplantedD.planted,A,B,C,B,C,D,()7.Alotofthings_bypeopletosavethelittlegirlnow.A.aredoingB.arebeingdoneC.hasbeendoneD.willbedone()8.-When_thiskindofcomputers_?-Lastyear.A.did;useB.was;usedC.is;usedD.are;used()9.TheGreatWall_allovertheworld.A.knowsB.knewC.isknownD.wasknown()10.Who_thisbook_?A.did;writtenB.was;writtenbyC.did;writtenD.was;written()11.Astory_byGrannyyesterday.A.wastoldusB.wastoldtousC.istoldusD.toldus,B,B,C,B,B,如何写说明文1.说明的先后顺序2.某产品的用途、特点3.充分发挥想象力，谈自己的感受。,Unit9,产品介绍的常用句型以及词汇：HereImgladtotellyousomethingwas/wereinventedbybemadeof/fromItis/Theyareusedforwiththehelpchangepeopleslifeimprovethequalityofpeopleslifeconvenientcomfortableimportanthelpfuluseful,发明改变了世界、改变了我们的生活。比如，电视和自行车给我们的生活带来了许多变化和便利。请你以“inventions”为话题，根据提示写一份值日报告。先介绍电视和自行车的用途，在发挥想象力，说说你想发明的东西，并说明其用途或发明的理由。,电视：信息丰富，开阔视野，休闲娱乐，辅助学习自行车：价格便宜，方便，出行有利环保，有益健康,Goodmorning,everyone!Imondutytoday.ItsJune5th.Itisfine.Everyoneishere.TodayImgoingtotalkaboutinventions.Inventionsarecreatedeverydaybecausepeoplewouldliketomakelifeeasier.TherearefamousinventionsliketheTVandbicycle.,Wewatchentertainmentprogramstorelaxourselves.Besides,somelearningprogramshelpsuswithourstudyonTV.Thebicycleisveryuseful,too.Wegotoschoolorworkbybike.Itsnotsoexpensivethatmostofuscanaffordit.Itmakesnopollution,whichisgoodforourenvironment.Whatsmore,bicycleridingisakindofexercisesportswhichisquitegoodforourhealth.Thoughtherehavebeenmanygreatinventions,Iwishtoinventakindofpenwhichcanhelpmewritemorequicklyandneatly.Thatsall.Thankyouverymuch.,被用来做2.带有可调整跟的鞋3.电控拖鞋4.改变鞋的款式5.上一节历史课6.私人电脑7.手控计算器8.我的一些朋友9.被发明10.被发明在187611.一项恼人的发明,beusedfordoingsth.beusedtodosth.shoeswithadjustableheelsbattery-operatedslipperschangethestyleoftheshoestakeahistoryclasspersonalcomputershand-heldcalculatorssomefriendsofminebeinvitedbybeinvitedin1876anannoyinginvention,Exercises,错误地2.不够薄3.足够咸4.使顾客高兴5.最后6.在的尽头/末尾7.薯片的历史8.撒了许多盐在上面9.炸了很长时间10.心情不好11.薄片的薯片,bymistakenotthinenoughsaltyenoughmakethecustomershappyinth
