效果分析：在教學(xué)活動中，我發(fā)現(xiàn)幾個問題：一、通過學(xué)生獨(dú)立練習(xí)、小組討論等方式能夠調(diào)動學(xué)生的積極性，基本達(dá)到預(yù)期效果。師生互動基本達(dá)到理想效果。二、學(xué)生能夠跟著老師的思路，我的主導(dǎo)地位和學(xué)生主體地位把握很好。三、準(zhǔn)備充分，但是普通話不怎么過關(guān)。所以，回想整個教學(xué)過程，我需要改進(jìn)的地方還很多，下一步，我會積極努力，多向老教師學(xué)習(xí)，盡快成長起來。教材分析：

本單元的中心話題是人類當(dāng)今面臨的環(huán)境問題，主要探討了“全球變暖”和“節(jié)約能源”等方面的問題。由于人類過多地使用不可再生能源，大氣中的二氧化碳的含量逐年增加，導(dǎo)致全球氣溫上升。通過學(xué)習(xí)本單元，讓學(xué)生了解可再生能源和不可再生能源，讓學(xué)生知道全球變暖的原因和嚴(yán)重后果，幫助學(xué)生樹立“節(jié)約能源，保護(hù)環(huán)境”的主人翁意識。ListeningandspeakingAbilitygoal:Enablethestudentstotalkaboutdifferentsourcesofenergyandexpresstheirownideas.Learningabilitygoals:Helpthestudentslearnhowtogivetheirideasabouttheuseoftheenergy.Emotionalgoals:Learntoprotectourenvironment.Teachingkeys:Improvethestudents’listeningabilityDifficultpoints:1.Improvethestudents’listeningability.2.Canusetheinformationfromlisteningtexttoclarifytheirownopinion.Teachingaids:computer,multi-media,blackboardTeachingmethods:listening,speaking,readingandwritingTeachingprocedure:Step1WarmingupⅠleadinginenjoyavideoWhathappenedinthisvideo?Whichgascanleadtoglobalwarming?Whatenergysourcescanproducecarbondioxide(CO2)?Doyouknowsomenewsources?Whatarethey?Step2ListeningPart11.Listentothetapeanddoexercise1.1.Whataretheenergysourcesmentioned?A.fossilfuelsB.waterC.windDsunE.nuclearF.tide2.ListentothetapeagainanddecidethestatementsareTorF1.Wecan’tstopusingfossilfuelsifwewanttoreducetheamountofcarbondioxideintheair.()2.It’sverysafeifweusethenuclearpower.()3.Thetechnologywehaveatpresentcanprovideenoughsunenergy.()4.Theenergywegetfromfossilfuelsisnotexpensive.()PartII1.Listentothetapeandchoosethebestchoices:1.AccordingtoLiBin’squestionhowmanythingsprofessorKeelingmentioned?A.twoB.threeC.fourD.five2.Wemustfindwaysthatwon’tput_________intotheair.A.oxygenB.carbondioxideC.hydrogen3.Whatarereallytheonestoblame?ThedevelopingcountriesB.Thedevelopedcountries4.Whomwewanttohaveagoodlife?A.humanB.ourselvesC.futuregeneration2.ListenagainandfillintheblanksLIBIN:Whatabout___________?Theydon’tcutdowntheiruseof____________.KEELING:No,theydon’t.However,thatisa___________wemustworkonasa____________community.Thatmeans_____________anddevelopingcountrieswillhavetoworktogether.LIBIN:Butit’snotthe______________countriesthatputmostofthecarbondioxideintotheair.Thedevelopedcountriesarereallytheonesto_____________.Step3DiscussingandSpeaking1.Talkaboutsomemeasuresofprotectingourenvironmentaccordingtowhatwelearnedfromthislisteningpassage2.Learntoexpressone’sopinion.Step4SummaryCauses:1.producingtoomuchcarbondioxide2.usingtoomuchplasticproducts,likeplasticbags.3.cuttingdowntoomanytrees4.wastingtoomuchenergysourcesMeasures1.walkingorridingabikeifyoucan2.recyclingpaper,cardboardandnewspaper3.tellingyourfriendsaboutglobalwarming4.usingenergy-savingproductslikelowenergylightbulbs5.plantingtree6.lessusingcomputerStep5Homework話題：請以CarsandEarth為題寫一篇120詞左右的短文描述越來越多的汽車對地球造成的負(fù)面影響，并提出至少兩種應(yīng)對措施。
