unit 3 a healthy lifei教学内容分析：本单元的中心话题为“健康生活”。听说读写等各活动主要围绕如何健身、怎样成为健康的人展开，其中涉及许多社会热点问题，如抽烟，吸毒，艾滋病学习与工作压力等影响健康的棘手问题。本单元引导学生讨论这些问题，目的在于让他们远离有损身体健康的活动，并养成良好的生活习惯。warming up 部分主要围绕健康问题和真正健康的人展开讨论。并提供了以下有关健康的话题：抽烟、喝酒、吸毒、饮食、健美、性健康、压力。同时，为了启发学生联想现实中的健康话题，附了六幅图片，供学生讨论、思考。pre-reading 部分提供了四个讨论题，主要让学生明白“抽烟有害于健康”这一道理。在我们周围有许多人抽烟，学生经常会听到抽烟的人谈论抽烟。故此，联系实际，让学生讨论：为什么有些人要抽烟？抽烟有哪些危害？等等问题，并让学生讨论身边的人和事。虽然学生没有抽烟的切身体会，但其周围不乏许多戒烟成功的例子，让学生体会交流一下，会有现实的作用，即学生或许会说服家人或亲戚把烟戒掉。教师还可以向学生介绍一些提供戒烟帮助的组织等方面的信息。reading 部分是爷爷写给孙子的一封信，共分两部分，第一部分主要是爷爷向孙子介绍他能长寿和充满活力的主要原因在于他健康的生活方式。而且还以亲身体会向孙子介绍了他年轻时吸烟上瘾的原因、抽烟的危害和戒烟的方法，依此告诫孙子把烟戒掉。并说明吸烟上瘾的三个原因：1. 尼古丁的药物作用；2. 习惯的驱动力量；3. 精神上的依赖性. 还有吸烟的危害：1. 伤害心脏和肺；2. 不孕；3. 影响身边不吸烟的人的健康；4. 味道难闻；5. 手指发黄；6.跑步速度慢；7. 不喜欢运动。第二部分提供了六种戒烟的方法：1. 制定计划；2. 下定决心；3. 破除旧习；4. 学习自我放松；5. 必要时请求帮助；6. 坚持不懈。comprehending 部分帮助学生对课文细节的进一步理解。共提供了三个练习题。练习1是表格填空，主要检查学生对课文内容的理解。练习2为讨论题，主要让学生对“爷爷”和“爷爷”的信作一评价，讨论“爷爷”是个什么样的人，学生可以用到文中的determined等形容词，也可以运用以前学过的评价人物的词语。练习3要求学生写一个劝告他人戒烟的提纲，不要超过五个句子。learning about language 的词汇部分设置了三项练习。练习1是词语替换练习，练习2是短文填空，帮助理解和运用课文中所学的生词。短文与课文内容相近，有助于课文的复习，同时又提供了学词汇的语境。练习3为词汇游戏，语法部分先通过到课文中找含有it的句子，让学生认识it的用法；然后简单介绍it 的两个用法。using language 部分综合训练学生听说读写的能力。包括一篇阅读文章，听力，会话和写作。阅读文章主要是介绍艾滋病毒和艾滋病的海报。听和说部分设置了三项练习。练习1要求学生选出萨拉担忧的问题。练习2通过听写蒂娜的话，复习提建议的交际用语，练习3以参加聚会为情境，让学生列举做与不该做的事情，旨在操练本单元的交际用语。写的部分要求学生给想拒绝吸烟却遇到困难的李晓雷写封信，帮助他想想办法。summing up 部分要求学生就吸烟、艾滋病等话题、词语和结构三个方面进行自我评价，判定学习情况。learning tip 部分介绍两种类型的问题：封闭式问题和开放型问题。两种类型的问题对于学生发展思维能力和训练英语能力都很重要。对于开放型问题没有统一的答案，只要经过深思熟虑就可以了；开放型问题有助于培养学生的发散性思维。ii教学重点和难点1. 教学的重点(1) 本单元的生词及重要短语。(2) it在句中做的各种成分，主要是形式主语，及表示“时间”、“距离”、“天气”等(3) 关注健康问题，认识到吸烟、吸毒的危害性，了解hiv/aids及其预防知识，树立对待hiv/aids病人的正确态度。2. 教学的难点(1) 了解各种危害人类健康的疾病，及其预防措施。(2) 学会表达警告、禁止和允许的日常交际用语。(3) 学习写劝告信。iii教学计划本单元分六课时：第一课时：warming up; pre-reading & reading第二课时：learning about language(1), using words and expressions (workbook), speaking task (workbook)第三课时：reading task第四课时：learning about language (2), using structures (workbook)第五课时：listening and speaking第六课时：writingiv教学步骤：period 1 warming up, pre-reading & readingteaching goals: 1. to make ss know what a truly healthy life is.2. to arouse ss to pay more attention to the healthy issues and realize the danger of smoking and drugs.3. learn some new words and expressions.teaching procedures:step 1. warming uppurpose: to activate ss and arouse them to talk about some healthy issues in our daily life.1. show the following two pictures to ss. ask ss what they are doing and whether smoking or drinking is good for health?
