III.教材分析与教材重组
1.教材分析
本单元以Cloning为话题,旨在通过单元教学,使学生了解克隆技术的优缺点,学会表达和支持个人观点,能用所学的有关Cloning的词汇去表述自己对这一新技术的观点和看法。
1.1WarmingUp提供了四幅有关Dollythesheep(多莉羊)Astrawberryplant(草莓植物)Twins(双胞胎婴儿)Identicaldogs(克隆狗)的图片,让学生用已有的知识和经验讨论对克隆技术的看法与观点。
1.2Listening是关于人类克隆的听力材料,难度中等。
1.3Speaking根据材料,四人小组合作,要求把自己对克隆婴儿的态度和感觉用相关的语言表达出来。
语言要得体,锻炼语段表达能力。
1.4Pre-reading是Reading的热身活动。
它要求采用与同学讨论交流的方式谈论有关克隆的相关知识。
1.5Reading是一篇介绍克隆技术的说明文。
1.6Comprehending第一题所给出的表格让学生根据课文内容列举克隆技术的优缺点。
第二题让学生根据所拥有的知识来评价作者的观点。
第三题要求学生用自己的语言阐述对克隆技术的观点并给出理由。
1.7LearningaboutLanguage分词汇和语法两部分,其中Discoveringusefulwordsandexpressions是根据语境在运用中掌握词汇。
Discoveringusefulstructures是通过阅读和补全句子来练习。
1.8UsingLanguage中的Reading,Discussingandwriting要求学生先读,然后完成四个任务型的作业。
即1.讨论并回答三个问题。
回答这些问题,2.讨论几种已经灭绝的动物,并且讨论哪种动物应该被恢复到这个世界上,并且给出理由。
3.listeningandspeaking让学生根据所听到的内容选择并列出文中人物观点。
2.教材重组
2.1从话题内容上分析,WarmingUp与Reading相一致;而从训练目的上分析与TALKING比较一致。
从教材份量来说,可将WarmingUp和Reading整合在一起,设计成一节任务型“阅读课
(一)(精读课)”。
2.2将Listening和Workbook中的LISTENING整合在一起,设计成一节"听力课"。
2.3将UsingLanguage与Workbook中的TALKING和SPEAKINGTASK结合在一起,设计成一节“口语课”
2.4将LearningaboutLanguage与Workbook中的USINGWORDSANDEXPRESSION整合在一起上一节“语法课”。
2.5将Workbook中的READINGTASK和PROJECT以及WRITINGTASK整合成一节“泛读与写作课”。
3.课型设计与课时分配
