福建省晋江市首峰中学高中英语《Unit 2 Working the land》教案 新人教版必修4

]福建省莆田市第八中学高二英语必修四《Unit2Workingtheland》教案1.教材分析本单元的中心话题是“农业”，学生通过讨论和阅读了解有关农业、农村和农作物种植的内容。让学生了解农业在整个人类生活中的重要性，了解农村生活，了解中国农民的生活现状，提高他们对农业的认识，并且帮助他们更深刻地理解农业科学家袁隆平的科学研究的价值。培养学生从小养成爱惜粮食，不铺张浪费的好习惯。同时让学生了解organicfarming以及它对人们生活的重要性，进一步扩大学生的关于农业方面的词汇量，并通过写一则海报提高学生的写作水平。1WARMING-UP通过提问有关农业、农村和农作物种植的内容，让学生谈谈自己对农村和农业劳动的认识或经验。教师可通过讨论让学生互相学习，相互交流经验以增加他们的农业知识。2PRE-READING部分有两组问题。在第一组问题中，讨论大米在东亚和东南亚国家人民生活中的重要性；而第二组问题则提出世界部分地区所面临的饥饿问题。由此激发学生对世界的关注，培养学生的同情心。3READING部分介绍中国著名的农业科学家袁隆平的生平和他的杂交水稻。第一段描述了袁博士的外表——他更象一个农民而不象一个科学家，农村就是他做科研的殿堂。他的科研成果就是超级杂交水稻。第二段描述他的家庭出身，学业，献身水稻科研的原因及所取得的成就。第三段告诉我们袁博士过着跟普通人一样的生活却干着伟大的事业。即使在功成名就之后，他也淡泊名利,有着无私奉献的高尚精神。4COMPREHENDING部分设计了三个练习。第一个是判断练习，学生根据课文中理解和收集的信息做出判断，甚至通过讨论才能做出判断。第二个是词语理解题。第三个练习提出问题，要求学生在阅读课文后作出回答,以检验他们的理解力和训练他们的归纳总结能力。5LEARNINGABOUTLANGUAGE部分学习本单元重点词汇和语法项目。词语学习部分采用给出词义而让学生从课文中找出与之匹配的词，然后用所找的词汇完成第二个练习中的短文，以及用课文中意义相近的词汇替换练习三句中划线部分。通过这三种练习帮助学生理解并能熟练应用课文中所学的词汇。语法部分通过从课文中找同义句引出动词的-ing形式，教师此时可引导学生找出其他的句子，以启发学生理解-ing形式的句法功能。练习二通过模仿例句，用-ing形式做主语代替动词不定式改写句子。练习三要求学生连接短语造句，让学生学习-ing形式作宾语的用法，并列举后面接动词-ing形式作宾语的动词。练习四则训练学生v-ing形式在实际生活中的应用能力。练习五则设计了一个游戏以丰富学生的想象力。6USINGLANGUAGE部分综合训练学生的听说读写能力。第一部分读写结合，学生先阅读文章，文章写的是OrganicFarmingorgreenfood,读完后要求学生写一个摘要。在此教师要首先强调写摘要时学生一定要抓住文章的主题并且运用所学的重要词语。听力部分通过回答问题来提高学生的理解能力和理解的正确性。Reading,speakingandwriting部分把读，说和写有机地结合在一起。假设你是一个“绿色食品”farmer，通过背景阅读，你要有充分的理由，利用所提供的句型，以对话的形式说服他人购买你的食品。最后为你的食品设计一个有说服力的广告。7SUMMINGUP部分要求学生归纳总结本单元内容、词汇和语法结构三个方面。8LEARNINGTIPS部分对如何提高表达能力提出建议。II．教学重点和难点1.教学重点(1)本单元的生词和短语；(2)掌握V-ing用法2.教学难点(1)学会写海报；III．教学计划第一课时：WarmingupPre-reading,第二课时：ReadingComprehending&LanguagePoints第三课时：LearningaboutLanguage&Grammar第四课时：UsingLanguageReadingII第五课时：WorkBookIV．教学步骤Period1WarmingupPre-reading,Reading&ComprehendingTeachingProcedures:Period1TeachingGoals:TodevelopSs’abilityofusingwordsandexpressions.TodevelopSs’abilityofspeaking.ToenrichSs’knowledgeoffarmingStepⅠGreetingandleadingin
