第二节（Period2）本节与上节相关性分析：本节课在上节课通过介绍过去的一些旧发明引入了三个句型――Whenwasitinvented?Whowasitinventedby?Whatisitusedfor?，经过大量的练习学生已经对他们了如指掌，在此基础上，本节课在继续巩固原句型的基础上了拓展了很多新发明，一方面扩充了学生单词量，另一方面通过听力（2a,2b）和口语训练（2c,3aand4），尤其是4这个环节，更进一步地提高了学生会话的能力，大大激发了学生的思维参与。课型：Listening&speaking时间：45minutes教材内容：SectionA2a,2b,2c,3a,3b,4.教学要求：1.Languagegoals:I.Words&expressionsheatedicecreamscoop,adjustableheels,battery-operatedslippers,lightbulb,microwaveovenII.KeysentencesWhenwasitinvented?Whatisitusedfor?Whowasitinventedby?2.Abilitygoals：Enablethestudentstousethepassivevoice.3.Emotion&attitudegoals：Enablethestudentstobeawareofdifferentinventionsaroundthemandhavetheabilityoffacingandsolvingtheproblem.4.Strategygoals：Enablethestudentstousewhattheyknowtoexplainnewwords.教学重点:Understandandusethenewwords,phrasesandthepassivevoicecorrectly.教学难点:Introducethenewinventionsaccordingtothelisteningmaterials.教学方法:InstigativemethodandTask-basedTeachingmethod教学手段:acomputer,blackboard,thelisteningmaterials,PPTTeachingprocedures（教学步骤）Teachingproceduresandways教学过程与方式TeachingstepsTeachingaimsTeacher’sactivitiesStudents’activitiesTeachingaidsStepI:RevisionToconsolidatetheknowledgethatstudentshavelearntinperiod1.1.AskSstorevisethestructureofdifferenttensesofPassiveVoiceandtrytotranslatesomesentencesusingthePassiveVoice.SaytogetherortelltheansweronebyoneMultimedia(PPT)Slide2,3,45StepII.Leading1.Toleadthenewinventionsbyrevisingthoseoldinventionslearntyesterday.2.Toimprovestudents’1.AskSstotalkabouttheinventionsbyusing:Whenwasitinvented?Whowasitinventedby?Whatisitusedfor?2.TelltheSs,1.FirstSsworkinpairsandactwhattheylearntout.2.Ssguessandanswer.3.ReadthenewwordsMultimedia(PPT)Slide6,7,8,9TeachingstepsTeachingaimsTeacher’sactivitiesStudents’activitiesTeachingaidstheabilityofdescribingthenewwordsinEnglish.Today,wewillgettoknowsomeinventionsinthemodernlife.3.Presentthepicturesoftheheatedicecreamscoop,adjustableheels,battery-operatedslippersandleadtheSstoguessthenamesandtheusagesofthemwiththefollowingquestions:Whatare/isthey/it?Whatare/isthey/itusedfor?aftertheteacher.TeachingstepsTeachingaimsTeacher’sactivitiesStudents’activitiesTeachingaidsStepII:Listening2a.2bToimprovetheSs’listeningSkills.1.AskthemtolistentotherecordforthefirsttimetoNumbertheinventions.2.Askthemtolistentotherecordforthesecondtimetomatch3.Checktheanswers.4.Askthemtolistentotherecordforthethirdtimeandreadaftertherecord.4.Simpleexplanations.1.Numbertheinventions.2.Listenandmatch.3.Readaftertherecord.4.Writedownsomenotes.Multimedia(PPT)Slide10,11StepIII:OralpracticeThisactivityprovidesoralpracticeAskSstoworkinpairs.RemindSsto1.Workinpairstotalk.Multimedia(PPT)Slide12,13TeachingstepsTeachingaimsTeacher’sactivitiesStudents’activitiesTeachingaidsaboutlisteningmaterial.Usingthetargetlanguage.usethecontentsneeded(thenameoftheinvention,thepeoplewhoinventedandtobeusedfor…2.AsksomepairstoactthemoutStepIVBrainstormingTohelpthestudentstoreviseandpresentthewordsaboutsomenewinventions.1.LettheSssaythewordsaccordingtothepictures.2.Memorychallenge.InteresttheSstorememberthenewwordsbyagame.1.Revisethewordsandrecognizethenewwords.2.Trytoremembertheorderofthewordsands...
