单元：Unit1Theworldofoursenses板块：Welcometotheunit课堂设计指导思想：本节课是听说教学课。在本课中，教师设计各种听说活动，鼓励学生就“五种感觉在自己学习生活中的重要性“展开广泛地讨论并大胆发表自己的观点。丰富多彩的图片展示使学生从视觉上产生差异，从而促使他们讨论：“Toseeistobelieve”是否绝对正确。最后通过残疾艺术家身残志坚，做出巨大成就的事例，使学生明白应该以积极热情的态度面对生活和学习。Teachingaims:1.EncouragestudentsspeakouttopracticetheiroralEnglish.2.Arosetheirinterestinlearningthisunitthroughactivities.3.Letthemknowtheimportanceofsensesindailylife.TeachingProcedures:Step1.Brainstorming（ppt5-6）Askstudentsthefollowingquestions:-1.Withwhatdoweseeandhear?2.Howdoweknowwhetheradishisdelicious?3.Howdoweknowthataflowerhasapleasantsmell?4.Whatdowedowhenwewanttoknowwhetherthewaterinthebasinishotorcold?5.Howdoweknowabouttheworldaroundus?Asweallknow,almosteveryonehasfivesenses,whichareusedeverywhereandallthetime.Welearnabouttheworldthroughthefivesenses.Weusethefivesensestostudy,workandrelax,buttherearesomepeoplewhohavelostoneormoreoftheirsenses.【设计说明】通过头脑风暴活动，引出话题，用浅显易懂的问题，激发学生的兴趣，激活课堂气氛。问题后教师的陈述目的是导入下一步的讨论。Step2Presentation（ppt7-8）1.Whatwouldhappenifyoulostoneortwoofyoursenses?Apersonwhocannotseeisblindandsomeonewhocannothearisdeaf.2.Doyouknowhowblindpeoplecanread?(Theycanreadbytouchingraiseddotswhichrepresentnumbersandletters.ThissystemiscalledBraille.)3.Howdothedeafcommunicatewitheachother?(Theyusebodylanguageorsignlanguage.)【设计说明】阅读短文“Fivesenses”,通过三个问题检测学生对其的理解。Step3Discussion---GroupActivity（ppt9）Lookatthefourpicturesandanswerthequestionbeloweachpicture.1.Whatcanyouseeinthispicture?2.Howwouldyoujudgethelengthofthetwolines?3.Howcanyouprovethatthetwolinesarestraight?4.Canthesymbolsbereadinonlyoneway?5.Whyarepeoplemisledbytheirowneyes?【设计说明】要求学生对四副图画进行仔细观察，展开小组活动，讨论看到什么图案。每小组一人向全班汇报。让学生明白，有些背景和线条误导了人的大脑，从而使人做出不全面的判断。Step4Languagestudy(ppt10-11)1.Fillintheblankswithwordsthathavesomethingtodowith“senses”:Whenhegotthere,he_________thattherewasadarkhole.He________intoit,butcould________nothing.He________withhisears,hecould_______nothing,either.He_________itforalongtime.He_______somethingstrange.He___________thesideofthehole.It______hot.Suddenlysomenoiseswere________fromthehole.It________likesomeonewascookinginside.2.Let’stalkabouttheimportanceofeachsense.e.g.Weseetheworldwithoureyes.Withoutthesenseofsight,wewouldliveintotaldarkness.We____with__________.Without_________,wewould___________________.【设计说明】设计两个练习，目的是用说的方法，让学生复习掌握表示感官类的动词名词的使用。拓展学生的思维，让他们明白这五种感觉在我们的生活学习中的重要性。Step5Discussion---Groupactivity(ppt12-20)1.Thereisasaying:Toseeistobelieve,isthatalwaystrue?2.Readthethreequestionsintheshortpassageanddiscussthemingroupsoffour.3.Reportyouranswerstothewholeclass.【设计说明】呈现四副图画，展开讨论：Thereisasaying:Toseeistobelieve,isthatalwaystrue?结论是：Inmostcases,thesayingistrue.However,sometimesoursenseswillcheatus.Toseetheworldclearly,weshouldalsobearmedwithscientificknowledgeandthinktwicebeforeaction.对教材上的三个问题进行讨论，列举一些身残志坚的成功者的事例，激励学生要做对生活充满热情的人，给这节听说课加入了德育教育的元素。Step6Assignments(ppt21)1.Previewthereadingpart,doexerciseC1andC2.2.Previewthereadingstrategy.【设计说明】本节课的目的之一即给下面的阅读课做铺垫，要求学生预习课文，是为了下一阅读课的进行扫清一些障碍，同时培养学生的预习习惯。
