教学案例 英语教学课例

英语上册Unit2Topic2SectionB教学课例一、课前分析本课是仁爱英语九年级上册Unit2LovingOurPlantTopic2Alltheseproblemsareveryserious.SectionB编写的教学设计。本话题通过“污染环保”这两个中心词展开,其中又分为3个子话题。子话题相对独立又相辅相成组成一个有机的整体。这是第二单元的第二话题的第二课时，在复习了上一课时学习学生应怎么做去保护环境，不定代词的用法的基础上，进一步学习树木在环保中所起的重要作用和节约用水。本课时旨在创造一个轻松、愉快的学习、交流环境，通过听、说、读、写来培养学生综合运用这些知识的能力。让学生去亲身体验，互动交流，创造性地去学习。并让学生通过有限的课堂实践活动能准确地用英语来表达所学知识。为了更好地在45分钟内最有效地实现教学目标，本人设计了直观生动的教学课件，从学生实际出发，对教材进行了必要的调整，先讲授1c的6副图画，引导出树木在环保中的作用，接着再学习1a,这样循序渐进，有助于学生理解。二、教学案例Themainactivitiesare1aand2.本课重点活动是1a和2。Ⅰ.Teachingaimsanddemands教学目标1.Learnsomenewwordsandphrases:sand,justnow,cutdown,changeinto,prevent,prevent…from,humanbeing,although,law,cutoff2.Continuetolearntheindefinitepronounandadverb.3.Learntotalkaboutpollutionanditsharm.Ⅱ.Teachingaids教具录音机/图片、多媒体课件Ⅲ.TeachingPlan教学方案Step1ReviewFillintheblankswiththegivenwords.(anybodyanythingothereverytherenobodyeveryoneotherseverybodynonesomething)(1)Noneofusneedworry.(2)Iknockedonthedoorbutnobodyanswered.(3)Someofthesebooksarebetterthanothers.(4)Shewasdrivingthecarwithonehandandwipingthewindowwiththeother.(5)It’sagoodlittlecarbutIamlookingforsomethingfaster.(6)Youcan’tbelieveanythingshesays.(7)There’re5,000peoplelivinghereandalmosteveryone/everybodyhastheirowncar.(8)He’sclevererthananybodyIknow.(9)I’velookedeverywherebutIcan’tfindit.Step2Presentation1.(呈现36页1c中的图片，学习新词汇。)T:FirstlookatPicture2.T: (指着第二幅图)Isthescenerybeautiful?Ss: Yes.T: OK.Let’slookatPicture4.Isitbeautiful?Ss: No.T: Whathashappenedtotheforest?Ss: Ithasgone.T: Yes.Peoplehavecutdowntoomanytrees.(板书并解释，要求掌握)cutdownT: PleaselookatPicture1.Alotofearthhasbeenwashedaway.Why?Ss: Becausepeoplehavecutdown…(教师引导学生回答。)T: That’sright.Treescanpreventthewaterfromwashingtheearthaway.(板书并讲解，且要求掌握。)prevent…from=stop…fromT: Let’slookatPicture3.Oh,mygoodness!Theforesthaschangedintodesert.(板书并讲解，要求掌握changeinto)changeintodesertT: PleaselookatPicture5.What’stheweatherlike?Ss: It’sbad.T: Yes.Thewindisblowingstronglywithlotsofsand.Wecallitsandstorm.(板书并讲解，且要求掌握sand。)sandsandstormT: Iscuttingdowntreesgoodorbadforus?Ss: It’sbad.T: Yes.It’sharmfulnotonlytohumanbeings,butalsotoanimalsandplants.(板书并讲解，要求掌握)humanbeingsT: Sowhatcanwedotoprotecttheenvironment?Discussingroupsoffour.S1: Plantmoretrees.S2: Stopcuttingdowntrees.S3: …T: Goodidea.Althoughwehavedonealottoprotecttheenvironment,it’sstillnotenough.Let’sworkharder.(板书，让学生猜测其汉语意思，且要求掌握。)although2.(让学生对1c的图片排序。)T:Doyouknowtherelationsbetweentrees,humanbeingsandsandstorms?Nowpleaselookatthepicturesin1candnumberthem.3.(听1a录音回答问题。)T: Justnowwetalkedabouthowsandstormscomeintobeing.Nowlistentothetape,andanswerthequestionsontheblackboard.(板书并讲解，要求掌握)justnow(板书)(1)What’stheweatherliketoday?(2)Whatshouldwedotoprotecttheenvironment?4.(让学生分成小组，读1a，提出不懂之处。小组内讨论解决各自提出的问题，最后全班共同讨论解决遗留问题。用此方式可以让学生充分参与到教学过程中来，进行自主探究学习，教师做补充讲解。)T:OK,pleaseworkingroups.Findandtalkaboutthelanguagepointsanddifficultpoints,thenI’llasksomestudentstogivetheirresultstoclass.(板书)Icouldn’tseeanything,andmyfacehurtwhileIwaswalkingdownthestreetjustnow.cutdownchangeintostop/prevent…fromdoingsth.Although…/…but…Step3Consolidation1.(让学生跟读1a录音，并注意语音语调。)T:Now,pleasereadafterthetape.Andpayattentiontothepronunciationandintonation.2.(让学生三人一组表演这个对话，稍后检查活动成果。)T:Pleaseworkingroupsofthree.Afterawhile,I’llaskseveralgroupstoactoutthisdialog.G1:…G2:…3.(让学生看1b的图片，完成1b。)T:Let’slookatthepicturein1b.Makenotesoftrees’functionsaccordingto1abyyourselves.(学生完成后，让学生一个接一个地把答案读出来。)T:Pleasereadyournotesonebyone.S1: …Step4Practice1.T: Nowweknowthatalotofwatercanbesavedbyforests.Whydowesavewater?Ss: Becauseitisveryimportant.T: That’sright.Withoutwater,we’lldie.Soweshouldprotectwater.(展示一条被工厂污染的河的图片，引出2中的新词汇。)T: Lookatthepicture.Canpeopledrinkthewaterintheriver?Ss: No.T: Whatcauseswaterpollution?Ss: Factoriesarepouringwastewaterintotheriver.T: Yes.Whatcanwedotostopwaterpollution?S1: Pulldownthefactories.S2: Writetothenewspaper.S3: …T: Yes.Wecanstopfactoriespouringwastewaterintoriversbycuttingofftheirwatersupply.(板书并讲解，要求掌握)cutoffAndwecanalsopasslawsagainstit.(板书、讲解且要求掌握)law2.T:Whatotherwaysofprotectingandsavingwaterdoyouknow?Read2anddiscussingroupsoffour.(小组代表报告，教师板书总结。)(板书单词tap，要求理解。)Step5Project1.(讨论如下问题，为写作做准备。)T: OK.Weknowwaterisveryimportanttohumanbeings.Nowpleasetalkaboutthefollowingquestions:What’stheimportanceofwater?Howshouldwesavewater?Whydowesavewater?What’stheimportanceofsavingwater?(讨论完后汇报结果。教师将关键词板书以利于学生写作。)2.Homework:(1)Findoutmoreinformationaboutwater.(2)Writeashortpassagewiththetitle“ProtectingandSavingWater”.板书设计：Alltheseproblemsareveryserious.SectionBcutdown 1.Icouldn’tseeanything,andmyfacehurtwhilechangeintodesert Iwaswalkingdownthestreetjustnow.humanbeings 2.Passlawsagainstwaterpollution.although…/…but… 3.Remembertoturnthetapoffw
