高中英语-Book 6 Unit 4 Global Warming 袁静教学设计学情分析教材分析课后反思

课标分析：本单元的中心话题是人类当今面对的环境问题，主要讨论了“全球变暖”和“节约能源”等方面的问题。由于人类过多的使用不可再生能源，大气中二氧化碳的含量逐年增加，导致全球气温上升。通过学习本单元，让学生了解能源分为“不可再生能源”和“可再生能源”，帮助学生树立“节约能源、保护环境”的主人翁意识。教材分析：Readingisapassagefromanenvironmentalmagazineforyoungpeople.Itputsforwardthepossibleeffectofincreasedcarbondioxideintheatmosphereanddifferentfrompointsofviewaboutit.Italsoanalyzesthecausesoftheearth’sincreasedtemperature.Itposesquestionsandencouragesstudentstothinkabouttheissues.Therearetwographsinitthattellusthe“temperaturedifferencefromlong-termaverage,1860—2000”and“carbondioxidecontentintheatmosphere,1957—1997”.Charactersinthepassage—DrJaniceFoster,GeorgeHambleyandCharlesKeelingareallrealpersonsandtheirviewsreflecttheviewsofsomescientiststoday.学情分析：本单元是关于全球变暖的内容，本来是学生比较感兴趣也比较关心的内容，但是课文里面有不少生单词，而且课文内容比较长，加上针对全体学生来说，这篇文章是比较难的，理解起来是有不少难度的，学生把单词掌握好了，课文要读很多遍才能理解透，学起来才会容易点。教学目标：Toknowthemeaningofthefollowingnewwordsandphrases:consume;random;phenomenon;subscribeto;fuel;catastrophe;TolearnaboutsomefactsandviewsaboutglobalwarmingTolearnhowtheinformationisorganized.Todevelopthestudents’readingabilitybyskimmingandscanningthepassage.教学重、难点Toenablethestudentstolearnaboutglobalwarmingandtodeveloptheirreadingability.Toenablethestudentstotalkaboutwhatweshoulddotopreventglobalwarming.学情分析：本单元是关于全球变暖的内容，本来是学生比较感兴趣也比较关心的内容，但是课文里面有不少生单词，而且课文内容比较长，加上针对全体学生来说，这篇文章是比较难的，理解起来是有不少难度的，学生把单词掌握好了，课文要读很多遍才能理解透，学起来才会容易点。测评练习：1.Wasitinthisplace_______theyoncebuiltatallbuilding?A.thatB.inwhichC.beforeD.which2.Itis_______heoftenbreakstheschoolrules________makeshisheadteacherunsatisfiedwithhim.A.what;thatB.that;whatC.that;thatD.because;that3.ItisbecauseEnglishisbeingwidelyusedatpresent_________.A.whywelearnithardB.thatwelearnithardC.whichwemustlearnD.whenweshouldlearn4.---Wasitwhathesaidorsomethingthathedid_____madeyoucrysosadly,Sarah?-----No,notreally.A.whichB.thatC.whenD.what5.__________thepeoplehavebecomemastersoftheircountry_________sciencecanreallyservethepeople.A.Itisonlythen;thatB.Itwasthat;whenC.Itisonlywhen;thatD.Itwaswhen;then观评记录：我们的大组组长韩老师：首先要对袁老师的这堂课给与充分的肯定，整堂课从设计到上的过程费了很大的心思，也是相当成功的，师生的互动也很好，课堂效果也很好。刘老师：个人觉得这堂课的内容设计非常好，课堂容量也很大，里面每个小题的设计都是既理解了课文内容又和高考紧密的结合在了一起，不足之处，没有学生的讨论。史老师：导入部分感觉有点突兀，过渡有点不自然，板书内容偏少。张老师：袁老师的个人基本功还是比较扎实的，讲课的时候感觉比较稳重，整堂课不紧不慢，娓娓道来本单元的中心话题是人类当今面对的环境问题，主要讨论了“全球变暖”和“节约能源”等方面的问题。由于人类过多的使用不可再生能源，大气中二氧化碳的含量逐年增加，导致全球气温上升。通过学习本单元，让学生了解能源分为“不可再生能源”和“可再生能源”，帮助学生树立“节约能源、保护环境”的主人翁意识。教材分析：Readingisapassagefromanenvironmentalmagazineforyoungpeople.Itputsforwardthepossibleeffectofincreasedcarbondioxideintheatmosphereanddifferentfrompointsofviewaboutit.Italsoanalyzesthecausesoftheearth’sincreasedtemperature.Itposesquestionsandencouragesstudentstothinkabouttheissues.Therearetwographsinitthattellusthe“temperaturedifferencefromlong-termaverage,1860—2000”and“carbondioxidecontentintheatmosphere,1957—1997”.Charactersinthepassage—DrJaniceFoster,GeorgeHambleyandCharlesKeelingareallrealpersonsandtheirviewsreflecttheviewsofsomescientiststoday.教学设计：Stepone:havearevision1.drought旱灾，干旱2.famine饥荒3.catastrophe大灾难4.flood洪水；水灾5.methane甲烷6.graph图表；坐标图7.Fahrenheit华氏的；华氏温度计8.fossil化石；矿物9.fuel燃料10.byproduct副产品Steptwo：doyoulikesongs?haveyouheardofMichaelJackson?Nowlet’senjoyasongsungbyMikeJohnson—theearthofthesong.Afterthisvideo,hereisthequestion:whatdidyouseeinthissong?orinotherwords,whathappenedinthevideo?Thissongisaboutenvironment.Sotodaywewilllearnsomethingaboutenvironment,oneaspectofenvironment–globalwarming.Stepthree:FastReadingWhowrotethemagazinearticle?Whatisthenameofthemagazine?Whatarethenamesofthethreescientistsmentionedinthearticle?Whatarethetwographsabout?Stepfour:StructureanalyzingThetextcanbedividedinto4parts,andchoosethemainideaofeachpartpartMainideaPart1(Paragraph____)
