课题Unit3DoingOurPartfortheEnvironment(CultureUnderstandingandLanguagePractice)课型CultureUnderstandingandLanguagePractice课时2授课班级授课时间90mins授课教师教材分析本课教学内容选自《英语拓展模块》第三单元“DoingOurPartfortheEnvironment”文化理解（CultureUnderstanding）和语言应用板块（LanguagePractice）。文化理解部分是一篇关于环境污染的语篇，主要目的是丰富学生对环境保护主题的理解，为学有余力的学生提供学习资源。语言应用板块由语法练习与词汇练习两部分组成，语法练习帮助学生复习代词和比较级的基本概念和用法；综合训练学生准确掌握及灵活运用代词和比较级的能力，同时认识到个人行为对环境的重要影响，牢固树立环保意识。学情分析语法知识是学生使用英语进行交际的工具，代词和比较级的使用方法和语用功能在学生日常生活和职场交流中发挥着巨大的作用。学生在基础模块学习过代词和比较级的用法，对其语法功能有了解，在选择恰当的词语补全语篇时可进行迁移作用，但学生对于不定代词、关系代词、同级比较等语用功能还无法准确理解，因而教师在课堂上通过短句、对话、长语篇的练习方式，由易及难，不断强化练习，巩固语法知识，增强学生自信心。学习目标KnowledgeobjectiveGraspthevocabularyandsentencepatternsaboutenvironmentalpollutionproblemsandthemeasurestopreventpollution.AbilityobjectivesBeabletounderstandthediscoursewiththethemeofenvironmentalpollutionenvironmentalpollutionproblemsBeabletoMastertheusageandpragmaticfunctionofpronounsandcomparativedegrees.EmotionalobjectiveBeawareofprotectingtheenvironmentisthecommonresponsibilityofhumanbeings.学习重难点Teachingemphasis:MastertheusageandpragmaticfunctionofpronounsandcomparativedegreesTeachingdifficulties:Applypronounsandcomparativedegreesaccurately教学方法小组讨论法、任务教学法、情景教学法课前准备PPT课件、语音素材、视频和图片教学媒体PPT课件、多媒体设备、语音素材、拓展资源包等教学过程教学环节教师活动设计学生活动设计设计意图Step1:WarmingUpThinkandanswer1.Whatisthepollution?2.Doyouknowwhichtypesofpollutionarethere?3.Whocausedthepollution?Isitharmfulforhumanbeings?Studentslookthepictureandreadthequestions,thenthinktoanswer.本部分以环境污染为主要话题，帮助学生更好地理解环境污染以其常见种类和对污染的思考。Step2:CultureUnderstandingReadandanswerWhatisthepassageabout?ReadandunderlineLetstudentsreadthethreematerialandunderlineStudentsscanthetexttogetthemainideaofthetext,andunderlinethetopic本环节通过以环境污染为主题的语篇,thetopicsentenceofeachparagraph.ReadandchooseAskstudentstoreadthethreematerialsandchoosethecorrectanswers.sentences.Studentsreadcarefullythepassageandcompletethequestions.总结出语篇提及的环境污染问题及防范污染的措施，感知环境保护是人类共同的责任。Step3：LanguagePointsaffect,effectthe+比较级，The+比较级，nowhereelsetogobebad/goodforforbidsbfromdoingsth.releasesth.Intosw.cleanenergytakeactionsapreciousresourceturnoffsaveenergyprotecttheenvironmentberesponsibleforsortthegarbageclothbagsplasticgarbageStep4：LanguagePracticeReviewandcompleteMakestudentsreviewthebasicknowledgeofpronounand.Makestudentsreviewthecomparativedegreeofadj.andadv.Letstudentsdoexercisesandgivesomeexplanation.ReviewandcompleteHelpStudentsmasterthesentencepatternofthecomparativedegreeofadj.andadv..Letstudentsdoexercisesandgivesomeexplanations.ReadandchooseReviewtheusefulwordsandexpressionsofthisunit.AskstudentstodoexercisesandgivesomeexplanationStudentsrecallthebasicstructureofverbsandthefunctionsofvarioustenses.Studentsreadthediscourseandmakeachoice.本部分以环境保护为主要话题，通过二选一的方式选择恰当的词语补全句子、语篇以及完形填空的练习，帮助学生巩固代词和比较级的语用功能，通过梳理知识系统，培养学生自主学习的能力.本环节主要是词汇练习活动，以环保主题的短对话和长对话为依托，在语境中练习、巩固本单元重点词汇，培养学生自主学习的能力。Step5:SummaryIhavemasteredthefollowingwordsandexpressions:affect,effectthe+比较级，The+比较级，nowhereelsetogobebad/goodforforbidsbfromdoingsth.releasesth.Intosw.cleanenergytakeactionsapreciousresourceturnoffsaveenergyprotecttheenvironmentberesponsibleforsortthegarbagecloth/plasticbagsIhavemasteredthefollowinggrammarpoints:possessiveadjectives:my,our,your,his,her,its...demonstrativepronouns:that,these...indefinitepronouns:each,something,anybody...thecomparativedegreeequalcomparisonStep7：Homework1.Recite
