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。 1.1 Warming Up 提供了四幅有关Dolly the sheep(多莉羊) A strawberry plant(草莓植物) Twins（双胞胎婴儿） Identical dogs(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。
1.2 Listening是关于人类克隆的听力材料，难度中等。
1.3 Speaking 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。
1.4 Pre-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。
1.5 Reading是一篇介绍克隆技术的说明文。
1.6 Comprehending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。
1.7 Learning about Language 分词汇和语法两部分，其中Discovering useful words and expressions 是根据语境在运用中掌握词汇。Discovering useful structures 是通过阅读和补全句子来练习。
1.8 Using Language中的Reading，Discussing and writing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. listening and speaking 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，Warming Up 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Warming Up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Using Language 与Workbook中的TALKING和SPEAKING TASK 结合在一起，设计成一节“口语课”
2.4将Learning about Language 与Workbook中的USING WORDS AND EXPRESSION整合在一起上一节“语法课”。
2.5将Workbook中的READING TASK 和PROJECT以及WRITING TASK整合成一节“泛读与写作课”。
