外研版高中英语必修三【教学设计】Module-4

--可编辑修改-Module4SandstormsinAsia教材分析本模块以Sandstorms为话题，旨在让学生深入了解沙尘暴的起因和对我国乃至整个亚洲的危害，并通过以“沙尘暴”和“环境保护”为话题的各种任务或活动，让学生掌握与沙尘暴和环境有关的词汇，了解沙尘暴方面的知识。培养学生用英语谈论沙尘暴及环保的语言技能，同时提高学生的环保意识。根据上述教材的分析特征，满足《高中英语教学大纲》对英语阅读的要求以及素质教育中要培养学生综合素质能力的要求，结合学生的英语能力普遍薄弱这一学情，我为这一课确定了如下三项目标：（1）知识与能力：首先帮助学生复习掌握必要的生词及培养学生掌握良好的阅读习惯和阅读方法---跳读、略读和详读等。同时注意开发和培养学生的记忆能力，观察能力、想象、比较和分析能力，以及实践运用能力等。（2）过程与方法：以课文整体教学为中心，让学生通过groupwork、pairwork等小组合作形式，运用不同的阅读方法，创设不同的情境，设置各种任务，使不同层次的学生都能够积极主动参与到课堂的各项活动中；充分发挥多媒体的作用，使课堂内容丰富，形象直观，从而为完成本节课的教学目标奠定基础。（3）情感态度与价值观：了解沙尘暴方面的知识。同时提高学生的环保意识。♦教学重难点【教学重点】（1）掌握一些与沙尘暴和环保有关的词汇。(2)学习表达有关沙尘暴和环保的话题。【教学难点】(1)谈论沙尘暴和环保，写有关环保的短文。(2)掌握阅读技巧，了解文章大意。课前准备多媒体课件辅助教学过程Period1LeadinStep1.WarmingupLeadthenewtopicSANDSTORMSinbyreviewingwhatwehavelearnedinModule3.(2m)hurricanetornadoearthquakesandstormlightningvolcaniceruptionhurricanetornadoearthquakesandstormlightningvolcaniceruptionaturaPeriod2Informationaboutsandstorms.Askstudentstoshowandintroducetheirmindmappingaboutsandstorms.（10m）Period3.ReadingskillsStep1Fastreading（5m）Matchthemainideawitheach.pamgraphStep2ListeningandDetailedreading(10m)Dotheexercises.Period4:DiscussionWhatcanwedotoprotectourearth?(10m)Period5:SummaryandHomework.(3m)Writeashortpassageaboutwhatwecandotoprotectourearth,accordingtothesuggestionsabove.EXERCISEAsandstormreferstoahighamountofwindoccurringinsandyareas,usuallyindeserts,wherethewindspeedisabletoliftthetoplayer（层）ofsandfromtheground,andpushitineverydirection.Thesandinvolvedinthesandstormcanreachheightsofabout3.05m—15.24m.Itisverydangeroustoexperienceasandstorm.Sandcangetintothenose,eyes,mouthandlungs.Ifyouhappentobecaughtinsandstorm,youmustprotectyourselfbywearingmasks,scarves（围巾）andsoon.Ifyou'redrivingwhensuchastormapproaches,it'sadvisedthatyoupullofftheroad,sinceit'sdifficulttocontinuedriving.Thisisalsoimportantsincevehiclescanfailinduringsandstormsandyoucouldendupstuckontheroad.Mostsandstormsoccourinspring,andduringthedaytime.ManyoftheareasaroundthePersianGulfandtheSaharaDesertareassociatedwiththemostseriousstorms.Sinceit'sanaturalphenomenon（现象）,itcan'tbeentirelycontrolled.Inareasthatarenaturaldesertregions,youcan'talwayspreventasandstorm.There'smuchevidencethattheplanetMars（火星）hasduststorms,andclearly,nohumanintervention介入）isresponsibleforsuch.Thoughitcanmovewholesanddunesanddestroycrops,asandstormisnotwithoutbenefit（益益处）.Ifyou'redrivinginasandstorm,you'dbetter.stopyourcarinthemiddleoftheroad.continuetomakeyourwaystopandaskforhelpstopyourcaronthesideoftheroadTheunderlinedsentenceshowsthat,anyway,sandstormsare.usefulB.uselessC.harmfulD.powerfulAccordingtothewriter,asandstorm.istheresultofhumanactivities.canbepreventedcan'tcompletelydisappearontheearthcan'tbeforecastWhatwillbetalkedaboutifthereisafifthparagraph?thecauseofsandstorms
