Unit5WorkingtheLandUsinglanguageChemicalversusOrganicFarming教材分析：(What):该阅读文本是usinglanguage的第二部分以“评估化学耕作和有机耕作(evaluatechemicalfarmingandorganicfarming)为活动主题，介绍了化学耕作和有机耕作的两种特点，分析了各自的优缺点，最后的结论是人类如果想要既吃得饱又吃得健康，同时保持环境的可持续发展，还有很长的路要走。(Why)文本启发读者从多角度思考农业耕作的方式，辩证地看待化学耕作和有机耕作的问题。在文本结构上，作者采用了“先分后总”的信息组织方式，先介绍化学耕作方式，再介绍有机耕作方式，最后谈了自己的看法——其实，目前并没有种耕作方式可以解决全部问题。学生可以在文中找到不同的证据，发表自己的看法。“吃得饱”和“吃得好”其实是相互制约的问题，启发学生辩证思考农业耕作的方式。(How)文本使用了说明、举例、对比等写作手法，并运用了大量的语篇标识词，例如:表示转折的however、but,表示举例的forexample、forinstance，表示并列和递进的and、also,表示补充信息的的inaddition，用以引出不同信息的asfor、asanalternative，用以引出原因和结论的because、therefore，等等。用这些标识词连接句子、构成语篇，也体现了文本较强的逻辑性和所说明内容的全面性。Keycompetences(核心素养)I.Languageabilities（语言能力）:Readandunderstandthestructureoftextandexpresstheirideasfreely.II.Learningabilities（学习能力）:Traintheabilitytodistinguishtheopinionsandfacts,andexplainthesupportivepoints.III.Culturalawareness（文化意识）:1.Learnabouttheimportantroleagricultureplayinoureconomicdevelopment.2.Understandthesignificanceofagriculturalsustainabledevelopment.IV.Thinkingqualities（思维品质）：Expresstheiropinionsaboutagriculturaldevelopmentanduseproperpointstosupportit.Teachingaims:1.Knowsomeknowledgeaboutchemicalandorganicfarming;2.Improvethestudents’readingandwritingabilities;3.Enablestudentstoknowaboutthebalancebetweenagriculturaldevelopmentandthehealthofpeopleandenvironment.TeachingImportantPoints1.Trainstudents’readingability.2.Encouragestudentstoexpresstheiropinionsonthechemicalandorganicfarming.TeachingDifficultPointsHowtoimprovestudents’readingandwritingability.TeachingMethodsActivity-basedteachingMulti-mediateachingCommunicativemethodsDiscussionandIndividualandGroupworkTeachingProceduresStepI.Before-reading1.AquestionaboutYuanLongpingtoreviewhisachievement._______________________________________________________________.2.Enjoyavideotoleadinthechemicalandorganicfarming.（设计意图：图片回扣先导知识，利用短视频激发学生的学习兴趣。）StepII.While-readingActivity1.MakepredictionLookatthetitleandpicturesbelow.Whatdoyouthinkthetextisabout?（设计意图：通过标题和图片，推测文章内容。）Activity2.Skimthetextthenmatchthemainideas(A-D)belowwiththeparagraphs.para1¶2A.Whatorganicfarmingispara3B.Whyman-madechemicalsarestillusedinfarmingpara4C.Organicmethodsforproducingrichsoilpara5D.Theproblemswithchemicalfarming（设计意图：通过略读，找出段落大意。）Activity3.Scanthetextandchoosethecorrectanswer.（Readingtips）Scanning(扫读)，扫读是定位细节信息的过程其目的是lookingforaspecificpieceofinformationorspecificwords。谈到Scanning就一定要提到定位词，定位词最好是形式固定且比较容易被“扫”到那么符合这样规则的阅读定位词有：人名、地名、机构名称等数词、特殊印刷字体的词等等）1.Whydidmanyfarmerswelcometheintroductionofchemicalfarming?A.Becausetheyarecheap.B.Theyareagoodwaytostopcropdiseaseandincreaseproduction.C.Theycancausedamagetotheland.D.Theydogoodtopeople'shealth.2.Fromthepassage,wecanseeorganicfarmingis_______.A.growingcropswithchemicalfertilisers.B.growingcropswithnaturalfertilisers.C.uselessinthecropdisease.D.veryexpensive.3.Whatdoesthetextmainlytellus?A.Theadvantagesofchemicalfarming.B.Theproblemoforganicfarming.C.Theproblemsofchemicalfarmingandadvantagesoforganicfarming.D.Chemicalfarmingisbetterthanorganicfarming.（设计意图：通过寻读，定位细节信息。）Activity4.Readcarefullyandfillintheblanks.（设计意图：阅读提升，把握文章脉络。）Activity5.Summarizethestructureofthetext.ChemicalfarmingdivideOrganicfarmingSummarize??（设计意图：总结文体分析，导入话题写作。）（写作技巧指导）：Payattentiontothetransitionsbetweenideas(过渡和转换).forexample,inturn,inaddition,infact,etc.（链接高考应用文写作，注重过渡词和转换词的运用。）StepIII.Post-reading：DiscussionWhatisyouropiniononchemicalororganicfarming?Topicsentence:Frommypointofview/Inmyopinion,________armingispreferableto__________farmingbecause______________________________________.Point1.Tobeginwith/Firstofall/Firstly,__________________________________.(detail)_______________________________________________________.Point2.Secondly/Then/Next,________________________.(detail)________________________________________________________.Point3.Lastbutnotleast/Inaddition/What’smore,_________________________.(detail)______________________________________________.Conclusion:Inclosing/Inconclusion/Allinall,______________________.（设计意图：链接高考应用文写作，训练提升写作能力。）StepIV.Homework:Writing-FinishyourwritingandPolishit.Whatisyouropiniononchemicalororganicfarming?教学反思：进一步研读《普通高中英语课程标准》，贯彻好高中英语学科核心素养目标，把握好新课标、新教材、新高考下的学生能力培养目标体系和要求，进一步梳理高中英语主题教学的框架，设计更为科学高效的英语课堂教学模式和思路。课堂教学更具有开放性和灵活性，更好地为学生走向国际化和现代化做好铺垫，切实提高学生地听说读写能力和思维品质，更好地运用丰富的网络资源和多媒体教学手段，扩大学生视野，丰富课堂活动，提高学生团队合作学习的意识和能力。好的教师，眼中永远有学生，学生的精彩才是课堂的精彩。怎样以学生为主
