Unit3Inventorsandinventionsdiscoveringusefulstructuresrevisionofpastparticiples本节课的话题是选修8Unit3Inventorsandinventions,具体内容是这个单元的discoveringusefulstructures:revisionofpastparticiples.这个单元的中心话题是发明创造，其中的语言技能和语言知识都是围绕这一中心话题设计的。但由于该单元过去分词的练习都是相对独立分散的，相互没有关联，不能构成意义连贯的语境，很难激发学生的兴趣，所以我选用了学生熟悉的动画片“喜羊羊与灰太狼”为蓝本，并以其中慢羊羊和灰太狼的发明为主线，设计了过去分词的练习。这些练习保留了书上练习的形式，但内容来源于真实的语境，能够更好地激发学生的兴趣。以下是书上的练习：Discoveringusefulstructures1.Findansunderlinethesentencesinhereadingpassagecontainingthepastparticipleusedastheattribute.Noteitsposition-eitherbeforeorafterthenoun.EXAMPLE:...butthereonlyseemedtobepowdersdesignedtokillsnakes.2.Completethefollowingsentencesbyusingthepastparticipleofsuitableverbs.understandbeatdisappointpleasesignembarrass1.Weneedanothercopyofthe_________________agreement.2.Heseemed________________bythefailureofhispatent.3.Shetriedtomakeherself________________whilegivinghertalk.4.Iwas_______________toseeourteam__________________byaweakerteam.5.Mymotherappeared_________________withthelanternsshehadmade.3.Completethepassageusingthecorrectformofthewordsbelow.welcomedevelopdesignimproverejecttestadoptIfyouwanttobeaninventor,youmusthaveaplan______tosolveaparticularproblem.Thisisnotaseasyasitsounds.Manyideas,__________afterweeksofresearch,maynotprovesuccessful.Manyunsuccessfulapproachesare___________,andonlythemostcreativeandsuccessfulonesare___________.Eachidea______________byyouwillneedtobe____________untilitleadsyouclosertoanewinvention.Oncethishardworkhasbeencompletedandthepatentcommitteehasapprovedyourdesign,youwillfindyournewinvention___________onallsides.4.Completethesentenceswithobjectsfromtheleftboxandthepastparticipleformoftheverbsintherightbox.myselfherpaintingsmytieyourbedroomburntidyperformthrowtheplaythecarsausagesomegueststakeupdisplayinvitestart1.Wesaw_________________________________onTVyesterday.2.Heleftthecarlightsonovernightandinthemorningshecouldn'tget__________________.3.Catherinewants_____________________________inthegallery.4.You'dbetterhave________________________beforeigethomefromwork.It'sinamess.5.Ifelt_____________________forwardwhenthebusstopped.6.Iwon'thave____________________withuselessdiscussion.7.Icannotbearthesmellof____________________onthebarbecue.8.Thehostfound_____________________tothepartywerelatebecauseoftrafficjams.以下是重新设计的内容：1.ObservethesentencesusedtodescribeMr.WolfandMr.SlowGoatandfindoutwhattheyareusedas:attribute,predicativeorobjectcomplement.1.Heistheleadingroleofthefamouscartooncalled"PleasantGoatandBigBigWolf".2.Heoftenfailstocatchanygoatandthereforeisbeatenbyhisdisappointedwife.3.Hehasalotofinventionsbutweoftenseehiminjuredbythem.4.Heisinterestedininventionandoftendomanyexperimentsinhislab.5.Everytimeheislostinthought,thegrassofwisdomwillgrowonhishead.6.Heoftenwalkswithhishandscrossedbehindhisback.2.Completethepassageusingthecorrectformofthewordsbelow.PleasantGoatandBigBigWolfScene1Mr.Wolf'sinvention：thespringshoesinspireannoyfrightendeterminedisappointimprovetieOnemorning,Mr.Wolftoldhiswifehewouldcatchsometoads（癞蛤蟆）forhertoeat.Hearingthese_______words,Mrs.Wolfgrabbedapantobeathim.Notwantingtoseehiswife______,M...
