Module4GreatinventionsUnit3Languageinuse本模块中，我们学习现在完成时和情态动词的被动语态。首先，我们一起先看一下本模块中出现的被动语态的句子：Thebatteryhasn’tbeenchargedforacoupeofmonths.Hasitbeenpublishedyet?Inthosedays,bookscouldonlybeproducedoneatatiebyhand.Todayinformationcanbereceivedonline.从以上例句可以总结归纳如下：时态肯定形式否定形式疑问形式现在完成时情态动词S+has/have+doneS+has/have+not+doneHas/Have+S+done?S+can/could/mustnot+be+doneS+can/could/must+be+doneCan/Could/Must+S+be+done通过这几个模块对被动语态的学习，我们可以发现只要明白了被动语态的各种时态、与情态动词搭配使用都是通过助动词be表现的这个规则，我们就可以自如地运用被动语态了。1.Completethesentenceswiththecorrectformofthewords.1.Ithinkonedaybooksmay_________(replace)bycomputers.2.Mybike_____________(leave)atschool,soIhavetotakethebustoschooltoday.3.Thebattery_________________(charge)yet.HowcanIusemyrecorder?bereplacedwaslefthasn’tbeencharged4.Papershouldnot__________(throw)away.5.BooksandCDscan____________(borrow)fromthelibrary.6.I'veboughtanMP3player—andabout1,000songshave__________________(download)ontoit?7.Hasthepen___________(mend)yet?Ineedtowritemyarticlewithit.8.Whathave______________(turnon)?Theradio?bethrownbeborrowedbeendownloadedbeenmendedbeenturnedon2.Workinpairs.Completethequizquestionsandchoosethecorrectanswer.1.what/use/tomakepapersincethe19thcentury?a)Wood.15)Silk.c)Cotton.2.where/thestoryofRomeoandJuliet/set?a)InNewYork.b)InAthens.c)InLondon.Whathasbeenusedtomakepapersincethe19thcentury?WhereisthestoryofRomeandJulietset?3.where/theworld'soldestpaper/discover?a)InIndia.b)InChina.c)InEgypt.4.howlong/computers/use?a)Forlessthan50years.b)For50years.c)Formorethan50years.Wherewastheworld’soldestpaperdiscovered?Howlonghavecomputersbeenused?3.Makequestionsandwriteanswers.1.what/can/use/tomakepaper?-(manythings)--whatcanbeusedtomakepaper?--Manythingscanbeusedtomakepaper.2.what/might/use/toreplacebooksoneday?(computers)3.where/can/music/keep?(onMP3players)--whatmightbeusedtoreplacebooksoneday?--Computersmightbeusedtoreplacebooksoneday.--Whereanmusicbekept?--ItcanbekeptonMP3players.4.Lookatthepicturesanddescribehowtheplacehaschanged.Usethewordtohelpyou.addchangeopenpaintputturnon5.Completethepassagewiththecorrectformofthewordsinthebox.callcleandevelopintroduceinventproducespreadusewriteFromabout.500BC,penswereusedforwriting.Thefeathersoflargebirds(1)____________anddried.Thepointofeachfeatherwassharpened.Thenpeopleusedthemtowritewithink.Manyfamousworks,suchasShakespeare'splays,(2)_____________withthesepens.Then,inthe18thcentury,apenWithasteelwritingpoint(3)____________.werecleanedwerewrittenwasdevelopedOnlyafewwordscould(4)____________,however,beforethewriterhadtofillthepenwithinkagain.Manyyearslater,thefountainpen(5)_____________fromtheseearlypens.In1950,aEuropeaninventedtheballpointpen.Thepopularityofwriting(6)_______quicklywiththe(7)___________oftheballpointpen.Eventoday,ballpointpensaremuchlessexpensive,comparedwithfountainpens.beproducedwasdevelopedspreadintroduction6.Workinpairs.Listenandsaywherethespeakeris.Givereasonsforyouranswer.a)Inalibrary.b)IntheBritishLibrary.c)IntheBritishMuseum.7.Listenagainandanswerthequestions.1.Whydidittakealongtimetoproduceabookinancienttimes?2.Whydomanyoldbookshavetobekeptawayfromthepublic?Becauseeachonewaswrittenbyhand.Becausetheyhavetobekeptsafelyawayfrodanger.7.Listenagainandanswerthequestions.3.Howhastheinventionofthecomputerhelpedtomakethesebookseasierforpeopletoread?4.Howcanthepagesofabookonacomputerbeturned?Theancientbooksaredownloadedontoacomputersoeveryonecanreadthem.Bypressingabutton.8.Completethesentenceswiththephrasesinthebox.1.Couldyou.imagineadigitalimageofYaoMingonthewall__________aposter?byhandforagesfromnowonratherthanratherthan2.Thingsmade__________areusuallymoreexpensivethanthoseproducedinfactories.3.Ihaven'tseenmybestfriend__________!4.We'reusingtoomuchpaper____________,I'mgoingtoreadallmymagazinesonline.byhandforagesfromnowonModuletaskPlanningaguidetoamuseum9.Workingroup.Prepareyourdiscussion.Eachchooseaninvention(e.g.thecomputer,thetelevisionorthecar).Researchhowyourinventionhasbeendeveloped,andmakenotesaboutwhatyoufindout.Thefirstcomputerswereverybig,butnowcomputersareverysmall.10.Discusswithyourgroup.Tellyourgroupwhatyouhavefoundoutanddiscusshowtheinventionmightbeimprovedinthefuture.Askyourgroupfortheirideas.Makenotesaboutyourdiscussionsandmakeafinallistofyourbestideas.11.Presentyourfindingstotheclass.Telltheclassaboutyourgroup'sideas.Listenanddiscusstheideasoftheothergroups.Voteonthebestideasandmakeafinalclasslist.Exercise根据汉语提示补全句子。1.Heoften____________(浏览)newspapersbeforebreakfast.2.Youcan’tdotwothings________________(一次).3.Allofthecakesaremade________________(手工地)4.Don’t_________________(与……相比)others.looksthroughatatimebyhandcomparewith5._________________(在…的开始)nextmonth,studentswillgotoschool.6.________________(在我回家的路上),ImetmyoldfriendSally.7.____________(结果),hewasmadeournewmonitor.AtthebeginningofOnmywayhomeAsaresult8.Iwanttogooutforawalk__________(而不是)watchTVathome.9.Shejumpedhigh_________(以便)shecouldreachtheapples.10.I’vetravelledtomanycountries,__________________(例如)JapanandAustralia.ratherthansothatsuchas/forexample1.Doyouknoww
