人教版高二英語選修六Unit4GlobalWarmingReading教學(xué)設(shè)計本堂課是這篇課文的第一課時，以學(xué)生掌握文章的主旨和具體內(nèi)容為主要目標。文章標題“Theearthisgettingwarmerbutdoesitmatter?”將非常清楚地告訴我們地球在不斷變暖的事實，，并提出疑問這究竟有沒有關(guān)系？本課分為兩部分進行：第一部分處理地球正在變暖的原因和事實依據(jù)，第二部分則帶領(lǐng)學(xué)生閱讀“這是否有關(guān)系？”，并引發(fā)自己的思考。因此，我設(shè)計了5個任務(wù)來完成本堂課的閱讀教學(xué)。其中4個任務(wù)以文本理解為基礎(chǔ)，導(dǎo)入部分設(shè)計了一個全球變暖的視頻，引出本單元的話題，再進行FastReading，接著是Carefulreading，在Carefulreading中，設(shè)計了trueorfalse；單選題；填表格；長難句理解；語法填空，在理解mainidea和trueorfalse部分時，讓學(xué)生討論解決。Discussion部分，采用圖片的形式呈現(xiàn)全球變暖的現(xiàn)狀，并通過圖片的形式討論解決的辦法。讓學(xué)生明白全球變暖問題日趨嚴重，我們還是要有應(yīng)對措施，加強環(huán)境保護。Homework部分，設(shè)計成寫作，把讀和寫結(jié)合起來。教學(xué)環(huán)節(jié)設(shè)計教師活動學(xué)生活動依據(jù)和目的Lead-in談話導(dǎo)入通過視頻引出Theworldisbecomingwarmerandwarmer然后過渡到題目GlobalWarming話題，教師播放視頻讓學(xué)生看到全球變暖的危害及影響，提出問題：Whathashappenedtotheworld?觀看視頻中冰山消融的畫面思考并回答問題。學(xué)生對視頻比較感興趣，從而激發(fā)學(xué)生閱讀課文的興趣。Fastreading一．根據(jù)下列問題，讓學(xué)生快速讀課文1.Whowrotethemagazinearticle?Whatisthenameofthemagazine?2.Whatarethenamesofthethreescientistsmentionedinthearticle?3.Whatarethetwographsabout?(onpage26)二.要求學(xué)生快速讀課文并分為4段：Para1Para2Para3Para4方法優(yōu)化：指導(dǎo)學(xué)生找每段的首句和尾句，然后總結(jié)整篇文章的大意。學(xué)生快速閱讀課文完成任務(wù)通過完成任務(wù)使學(xué)生粗略地了解文章結(jié)構(gòu)和主要信息，培養(yǎng)學(xué)生的概括能力。Carefulreading一．.TrueorfalseReadthearticlecarefullyandfinishPart2onPage271.Thetemperaturelastcenturydidn’tincreasemuch.()2.JaniceFosterbelievesthatglobalwarmingiscausedbyburningfossilfuels.()3.Carbondioxideisabyproductofburningfossilfuels.()4.Floodingcouldbeoneoftheeffectsoffutureglobalwarming.()5.GeorgeHambleyisworriedabouttheeffectsofcarbondioxideonplantgrowth.()6.Itisclearwhattheeffectsofglobalwarmingwillbe.()二.Multiplechoice1.Thepurposeofthefirstparagraphisto_______AintroducethewriterBexplainachangeCintroducethetopicDraiseaquestion2.Thegraphsareusedto_____AillustratepointsbyprovidingevidenceBtellthechangeoftemperatureCtellthecontentofcarbondioxideintheairDinterestthereaders3.Greenhousegasesreferto________AcarbondioxideBtheburningoffossilfuelsCthebyproductsoftheburningoffossilfuelsDcoal,naturalgasandoil4.Greenhouseeffectinthefourthparagraph________AisanaturalphenomenonBhappenswhenthereistoomuchcarbondioxideCdoesgreatharmtohumanbeingsDmakeslifeforhumanbeingsbetter.填表格：Fillintheblanks：ThetwodifferentviewpointstowardstheeffectsofglobalwarmingbetweenDr.JaniceFosterandGeorgeHambley五.語法填空On__otherhand,therearethose,likescientistGeorgeHambley,_____believethatweshouldnotworry______highlevelsofcarbondioxideintheairandsomescientists’concernsaboutglobalwarming_____(be)justspeculation.He_______(predict)thatanywarmingwillbemildwithfewbadenvironmentalconsequences.Infact,hestates,“Morecarbondioxideis______(actual)apositivething.Itwillmakeplantsgrow_______(fast);cropswillproducemore;itwillencourageagreaterrangeofanimals,allof________willmakelifeforhumanbeingsbetter總結(jié)考查角度：小組合作探究1.解決關(guān)于細節(jié)理解的題目，trueorfalse2.讀課文，完成兩位科學(xué)家的觀點對立部分3.讀第八段，完成語法填空部分。培養(yǎng)學(xué)生獲取信息、分析和判斷推理的能力，從而提高學(xué)生的閱讀能力。Discussion總結(jié)與升華1.通過圖片討論全球變暖的危害和下一步的措施2.通過這節(jié)課的學(xué)習(xí)你有什么收獲？為了保護地球，我們每個人都要行動起來。讓學(xué)生寫一篇關(guān)于節(jié)約資源和保護環(huán)境的作文引起學(xué)生共鳴，喚起學(xué)生的環(huán)保意識，培養(yǎng)學(xué)生語言運用、合作學(xué)習(xí)的精神。把讀和寫結(jié)合起來，培養(yǎng)學(xué)生的寫作能力。Homework附教案：Step1：LeadinNowwatchthevideoandfindoutwhathashappenedtotheworld？Step2：FastReading1.Whowrotethemagazinearticle?Whatisthenameofthemagazine?2.Whatarethenamesofthethreescientistsmentionedinthearticle?3.Whatarethetwographsabout?(onpage26)4.Readthetextagainandtrytogetthemainideaofthearticle.Matchtheline（連線）4partsmainideaPart1(para1)IllustratehowglobalwarmingcomesaboutPart2(para2)IntroduceadebateovertheissueofglobalwarmingPart3(para3-8)It’suptoreaderstothinkanddecidewhetherpeopleshoulddosthaboutglobalwarmingornotPart4(para9)ListtwodifferentattitudesamongscientiststowardsglobalwarmingStep3：Carefulreading一．.TrueorfalseReadthearticlecarefullyandfinishPart2onPage271.Thetemperaturelastcenturydidn’tincreasemuch.()2.JaniceFosterbelievesthatglobalwarmingiscausedbyburningfossilfuels.()3.Carbondioxideisabyproductofburningfossilfuels.()4.Floodingcouldbeoneoftheeffectsoffutureglobalwarming.()5.GeorgeHambleyisworriedabouttheeffectsofcarbondioxideonplantgrowth.()6.Itisclearwhattheeffectsofglobalwarmingwillbe.()二.Multiplechoice1.Thepurposeofthefirstparagraphisto_______AintroducethewriterBexplainachangeCintroducethetopicDraiseaquestion2.Thegraphsareusedto_____AillustratepointsbyprovidingevidenceBtellthechangeoftemperatureCtellthecontentofcarbondioxideintheairDinterestthereaders3.Greenhousegasesreferto________AcarbondioxideBtheburningoffossilfuelsCthebyproductsoftheburningoffossilfuelsDcoal,naturalgasandoil4.Greenhouseeffectinthefourthparagraph________AisanaturalphenomenonBhappenswhenthereistoomuchcarbondioxideCdoesgreatharmtohumanbeingsDmakeslifeforhumanbeingsbetter三.Fillintheblanks：ThetwodifferentviewpointstowardstheeffectsofglobalwarmingbetweenDr.JaniceFosterandGeorgeHambleyDr.JaniceFosterGeorgeHambleyCarbondioxidehascausedtheglobaltemperatureto__________.Anincreaseoffi
