Unit6 When was it invented教案（6课时）人教版九年级英语全册

Unit6Whenwasitinvented?单元教材分析本单元围绕“发明”这一话题，学习了解一些重要发明的历史，学习一般过去时的被动语态。SectionA介绍了我们日常生活中的一些常见物品的发明历史，如电视、电话、拉链、茶叶等。内容上包括谈论它们的发明时间、被什么人发明、它们的作用和发展等；从语言结构上，学习被动语态的过去时，单元主题图由四副小图组成，呈现的是现代生活中的常见用品：电视、电话、电脑和小汽车。从运用Ithinkitwasinventedbefore/after…讨论图片中物品发明的先后顺序开始，到听说训练本单元的重点语言结构：Whenwasitinvented？Itwasinventedin…，Whowasitinventedby？Itwasinventedby…，Whatwas/isitusedfor？Itwas/isusedfor…不断深入学习，再进入阅读训练，训练学生的阅读技巧，学习拓展词汇和语言结构。SectionA的重点是培养学生运用被动语态的意识，掌握更多的动词过去分词形式。SectionB依然围绕发明创造这个话题，要求学生继续学习巩固相关的内容和语言知识。在语言技能方面，对听说读写的专项训练和综合训练在本部分里都有体现。在语言策略上，提出让学生学习使用思维导图，以加深对文章的理解和对知识的记忆。在听力训练过程中，需要学生运用反义词、信息综合判断等，训练捕捉信息、处理信息的能力。在阅读训练中，需要学生学习和掌握如何利用思维导图帮助理清、记忆阅读语篇中的相关信息，把获取的信息转换成图形来帮助记忆。积极运用阅读策略有助于学生更好地掌握文章要点和细节等信息，降低语篇的学习难度，也有助于培养学生主动学习的习惯。单元目标1.理解、掌握和运用与发明和发明史相关的生词和短语,理解、掌握和运用一般过去时被动语态的结构。2.能够运用被动语态描述发明及发明史。对发明和发明史的学习使学生产生热爱发明的感情。3.通过了解中美发明及发明史，更好地理解人类发明文化中的瑰宝。4.通过对比分析,掌握一般现在时和一般过去时被动语态，用思维导图的方式进行阅读，提高阅读理解的有效性。5.教师在课堂教学中要关注学生的创新意识、创新思维、创新能力。要培养学生质疑问难;要提倡和引导学生求异思维，要鼓励学生能用不同的语言表述同一个事物;要激励学生敢于标新立异,即使学生的创见是错误的也值得欢迎。6.教师在课堂教学中要创设民主、平等、和谐愉悦的教学氛围。课堂上要让学生多发言，无论学生的种族、地域、性别、贫富，都要一视同仁，更要关注心理上、经济上、学习上的弱势群体。要因势利导，培养和塑造学生的道德规范和完整人格。教法导航1.以任务型教学作为课堂教学理念、利用整体语言教学法、情景教学法、交际教学法等。2.在教学中创设切实可行的任务型教学活动、突出交际性。3.教师为主导、学生为主体、任务为基础，注重实用性。4.引趣激趣策略，创设情景调节气氛，引发激发学生兴趣。学法导航多读善思，小组合作、探究、学习、交流课时分配Period1:SectionA(1a-2d)Period2:SectionA(3a-3c)Period3:SectionA(GrammarFocus-4c)Period4:SectionB(1a-1e)Period5:SectionB(2a-2e)Period6:SectionB(3a-SelfCheck)课时教案Period1SectionA(1a—2d)授课时间________实有人数_______缺席人数______缺席原因______【课时目标】重点单词：heel,scoop,electricity,style,project,pleasure,zipper,daily,website,pioneer,list,mention重点短语：withpleasure,suchagreatinvention,inourdailylives,haveapoint掌握以下句型：（1）—Whenwasthetelephoneinvented?—Ithinkitwasinventedin1876.（2）—Whataretheyusedfor?—Theyareusedforseeingatnight.4.能谈论物品被发明的时间、发明者，表达某发明的用途。5.了解一些近现代发明的时间及用途，激发自己热爱发明的情感。培养想象力，善于观察事物。面对难题，用积极的态度去解决，发挥想象力，认识世界，改造世界。【教学重难点】1.本课时的单词、词组和句型，学习运用一般过去时态的被动语态。2.学会询问发明时间及用途的基本句型：—Whenwasthetelephoneinvented?—Ithinkitwasinventedin1876.—Whataretheyusedfor?—Theyareusedforseeingatnight.运用一般过去时态的被动语态来讨论发明的发明时间及用途。【教学过程】Step1WarmingupT:Doyouknowwhattheseinventionsare?S1:It’sacar.S2:It’satelephone.S3:It’satelevision.T:Doyouknowwhotheseinventorsare?S1:KarlBenzS2:AlexanderBellS3:J.L.BairdLetSsmatchtheinventionsandtheinventors.Step2PresentationT:KarlBenzinventedthefirstcarin1885.Thefirstcarwasinvented(byKarlBenz)in1885.Step3Talking1.Lookatthepicturesin1a.Discusswithyourgroup,inwhatorderdoyouthinktheywereinvented?Trytonumberthem[1-4].2.Ssdiscusswiththeirpartnersandnumberthepictures.3.Talkingabouttheinventions:A:IthinktheTVwasinventedbeforethecar.B:Well,IthinktheTVwasinventedaftertheTV.Step4Listening(1b)1.T:TellSslookatthepicturesandyearsontheleft.2.PlaytherecordingfortheSstolisten.3.Sslistentotheconversationandtrytomatchtheinventionwiththeproperyear.4.Playtherecordingagain.5.Checktheanswers.Step5Pairwork(1c)1.Sstrytoremembertheinventionandtheyear.2.StudentB,coverthedates.StudentA,askStudentBwhenthethingsinthepicturein1bwereinvented.Thenchangerolesandpracticeagain.3.Letsomepairsaskandanswerinpairs.e.g.A:Whenwasthetelephoneinvented?B:Ithinkitwasinventedin1876.Workon2a.T:TellSstheywillhearsomeinterestinginventions.1.Lookatthepicturesin2a.Discussthethingswhattheyareusedfor.2.PlaytherecordingfortheSstolistenandnumberthepictures.3.Playtherecordingagaintochecktheanswers.Workon2b.1.LetSsreadthechartbelow.ExplainsomemainsentencesfortheSs.Makesuretheyknowwhattodo.2.PlaytherecordingfortheSstofillintheblanks.3.Playtherecordingagaintochecktheanswers.4.Listenagainandfillintheblanks.Step6Pairwork(2c)TellSstomakeconversationsusingtheinformationin2b.MakeamodelfortheSs.A:Whataretheshoeswithspecialheelsusedfor?B:Theyareusedforchangingthestyleoftheshoes.Step7Listening.Listento2dandanswersomequestions.1.WhatarePaulandRoytalkingabout?________________________________________________________________2.Whenwasthezipperinvented?________________________________________________________________3.Whendidthezipperbecomepopular?________________________________________________________________Step8Languagepoints1.Explaintheusageofinvent,pleasure,mention...2.Explaintheotherusagesofbeusedfor,doseem,haveapoint...3.Readthewordsandphrases.Step9Exercises1.Showsomeexercisetopracticethekeywords,thetargetlanguageandkeysentences.2.Checktheanswersonebyone.Step10Homework1.Listento1band2b.2.Makeaconversationaboutsomeinventions.【拓展延伸】【板书设计】Period2SectionA(3a—3c)授课时间________实有人数_______缺席人数______缺席原因______【课时目标】1.重点单词：low,somebody,translate,lock,earthquake,sudden,allofasudden,biscuit,cookie,instrument2.重点短语：byaccident,sometime,duringthe6thandthe7thcenturies,takeplace,without3.重点句型：(1)ItissaidthataChineserulercalledShenNongwasthefirsttodiscoverteaasadrink.(2)Thebookdescribeshowteaplantsweregrownandusedtomaketea.(3)Italsodiscussedwherethefinesttealeaveswereproducedandwhatkindsofwaterwereused.(4)ItisbelievedthatteawasbroughttoKoreaandJapanduringthe6thand7thcenturies.4.进行一步复习巩固学习SectionA部分所学的生词和词组。5.进一步学习运用一般过去时态的被动语态。6.掌握主动语态变被动语态的方法，并通过不同方式的练习，来熟练运用。【教学重难点
