Unit10FrighteningNature一、教材分析本课是人教社全日制普通高级中学教科书（必修）高中英语第二册上第十单元的第一课时的教学设计。这一课时里要完成三个小模块的任务：warmingup，listening及speaking。本单元主题为Frighteningnature。作为该单元第一课时，主要是激活学生关于自然灾害的思维，引起学生对自然与人类日常生活关系的思考，并能就自然问题，表达感情、焦虑和畏惧。二、学生分析自然灾害与人类日常生活关系密切，很容易调动学生的积极性，投入到课堂中来。但在完成任务时，学生仍有一定难度，尤其是听力部分涉及到美国地图及天气情况介绍。对美国地理知识了解不多的学生会在完成听力训练任务时有一定难度。因此在处理教材时，会根据情况有所调整以便降低学生完成任务的难度。三、设计思路本堂课主要采用任务型教学途径，这种途径强调以应用为动力，以应用为目的，以应用为核心，即为用而学、用中学、学了用的教学途径。学生带着任务学习，在完成任务的过程中逐渐生成知识，形成技能。本课将通过任务型教学，努力达到课堂活动目的。四、教学步骤Teachingcontent：Unit10FrighteningNature：warmingup,listening&speaking.Teachingaims：Totalkaboutnaturaldisasters:volcanohurricaneandtyphoon.Tomotivatestudentstogetmoreinformationaboutnature.Tostrengthenstudents’abilityoflisteningandspeaking.Toinspirestudentstoexpressemotion,suchasanxietyandfear.Teachingimportantanddifficultpoints：Makesurestudentsgetawareofwhatourtopicisinthisunitandknowwhattosayaboutthistopic.EnablestudentstoknowsomethingaboutgeographyandweatherinAmerica.Practiceexpressingtheirfeelings.Teachingmethods：task-based;students-centered;equipment-aided;dialogue.Teachingprocedures：StepⅠ．Greetingsandlead-inByaskingquestionslike“Whatistheweatherliketoday?”theteachercanguidetheSstotalkaboutweather.Theycananswerit’sfine/cloudy/rainy/snowy.It’sanordinaryday.Theweatherisusuallynormal.I’llshowthempictures.Inthisway,studentscanbrainstormasmanywordsastheycanbydescribingthepictures.Theusefulwordsandphrasestodescribeweatherareasfollows:coolanddryair;warmandmoistair;showers;thunderstorms;snow;strongwinds;storms;hurricane;typhoon;sunny;cloudy;rainy;fine/nice……ThewordsmayhelpSshaveabetterunderstandingofthefollowinglisteningtext.StepⅡ．Listening一、Listentothefirstparagraphofthelisteningtextandanswerthefollowingquestions:1．Whatdowecallthistypeofradiomessage?2．Whataretheplaceandthetimethatthisradiomessageisfor?ThenshowthemamapoftheUSAandmotivatetheSstotalkaboutwhattheweathermaybelikeindifferentpartsoftheUSAandwhichareashurricanesaremostlikelytohit.二、Listentothetextagainandfillintheblankswithinformationfromthetext.RainornottemperaturesTheNorthwestTheMidwestYES68-72FTheEastYES100FYES75F三、Listentothetextonceagainanddiscussthefollowingquestions.1．HowshouldyouprepareforthedayifyougofishingintheGreatLakesregion?2．InwhichpartoftheUSAshouldcardriversbecareful?3．Whichletterwouldthenameforthesixthhurricanein2005beginwith?4．Whathappenswhenahurricanehitsthecoast?Byansweringthesequestions,Ssmaygetawarethatnaturehasmuchtodowithourdailylife;ontheotherhand,thefourthquestioncanguideustotalkaboutbadweatherandhowwefeelaboutit.StepⅢ．SpeakingJustnow,wetalkabouthurricanesandwhathappenswhenahurricanehitsthecoast.Now,let’slookatsomepicturesabouthurricanesandjustthinkhowyou’llfeelandbehaveinsuchasituation.Studentcanbrainstormmanywordsandexpressionsbytalkingaboutthehurricane:Howterrible!Idarenotgoout.Ithinkitisveryfrightening.It’safrighteningthing.I’llstayoutside.I’mfrightened/scaredtodeathwhen…Igetveryupset!Ithinkit’sveryunpleasant.I’mafraidof…Itmakesmefeelveryworried.What’sreallyscary…Hegetsintoatotalpanicwhen…Itmakesmyhairstandonend.Whatterrifiesme…Thenlistentoadialogueandpracticetalkingaboutthingslikelightning,volcanoes,earthquakesnakes,drought,sandstormsandsomethingelse.Theexpressionstheybrainstormwillbeofgreathelp.AskSstoworkinpairandtoactouttheirdialoguesinfrontoftheotherSs.Preparesomemodelsandpicturesshowingnaturaldisastersorfrighteningscenestocreateanatmosphere.StepⅣ．HomeworkWriteashortpassagedescribingsomethingfrighteningyouonceexperienced.分析：1．利用多媒体制作课件，加快了课堂的节奏，调动了学生的积极性,使课堂呈现更具直观性。2．充分利用电化教学手段，创设一定的情景，把生活中的交际场面搬到课堂上来，让学生在听时就身临其境，在角色参与中得到听与说的训练。3．教学过程体现了素质教育的全体性，课堂步骤由浅入深，由易到难，环环相扣，使学生循序渐进的生成知识，形成技能。4．使用图片的呈现功能，降低学生理解文段的难度，充分树立学生学习的信心，达到交流的目的。
