8、点,让学生在交流中发现和了解大自然的奇妙和美丽；通过阅读奇闻故事,使学生从一个侧面了解人类与动物的关系；一篇与海底动植物相处的感受的日记,把学生带入人与自然和谐相处的美好境界.本单元用梯次递进的方式让学生运用已有的自然知识、亲身体验、所掌握的语言知识和技能,在阅读、听新闻和专家评述、讨论、写故事、编剧本、排练演出等多项语言功能运用的过程中,深入学习、了解海洋动植物和大自然,并学习用英语表达对它们的感受、关切和热爱,从而在学习和运用语言的同时,强化对海洋生物和大自然的保护意识.本单元实现了语言学习和传播先进思想的完美统一.1.1 Warming Up设计了两个活动.第一个活动用两个提问直接导入本

9、单元的中心话题,也是学生最感兴趣的话题海底动物和植物,要求学生以互相交流的方式更多地了解海底世界.紧接着是小组活动,要求学生将已知的海洋动植物列表归纳,并谈论自己最喜爱的海洋动物或植物.这一部分的设计为下一步的课文学习以与后边的听、说、读、写在内容方面打下了伏笔.1.2 Pre-reading是Reading文图并茂的内容简介.虎鲸帮助捕鲸人在每年须鲸迁徙时捕捉须鲸的奇闻轶事会立刻激起学生的阅读兴趣.1.3 Reading是一篇题为Old Tom the Killer Whale的故事,其中包括两篇关于虎鲸的奇闻轶事.第一篇讲虎鲸如何帮助捕鲸人捕捉须鲸,过程奇妙有趣.第二篇讲虎鲸如何从鲨鱼群中

10、救出捕鲸人,情节惊险感人.学生通过对课文的阅读理解,会由衷地感激这些可爱的海洋动物对人类忠实的帮助和巨大的贡献,同时习得阅读故事的技能.1.4 prehending设计了根据课文内容描述Old Tom和捕鲸人的关系, 旨在引导学生在阅读理解的基础上进行再创造.第二题根据课文回答问题,其目的是评价学生对文章的理解程度.第三项是小组讨论,中心论题你是否同意禁止捕鲸直击本单元思想内容主题环境和动物保护.整个活动设计梯次分明,思想教育意义和语言学习意义两条线共同逐步深入,以达到阅读理解的最佳效果.1.5 Learning about Language分为词汇和语法两项.词汇部分帮助学生学习用适当的形式

11、和意义使用词汇和短语,旨在培养学生运用英语词汇和短语的能力.语法项目是复习动词-ing形式的被动语态.要求学生用正确的-ing形式完成单句填空和补全句子来操练这一语法项目.-ing形式的被动语态在语法学习中是个难点,教师可以在此基础上做些拓展性和巩固性的练习设计.1.6 Using Language是一个综合性学习项目,包括阅读与讨论、讨论与写作、说话与写作.阅读与讨论 的主体是一篇与海底动植物相处的感受的日记,其后设计了四个活动环节：速读选择信息；细节列表；词汇学习；语法学习形容词连用.讨论与写作共有两项任务：一是让学生以小组活动的形式讨论所给出的日记中的描述性词语的意思和描述方式；二是让学

12、生用上其中三、四个短语写一小段描写一个地点的一种动物或植物的短文.这种分类描写的方式非常有利于对学生的写作训练和指导.读、听、说共设计了五项活动：第一项是在听之前阅读一则观鲸旅游的广告并就此讨论有关问题；第二项是听一段对话选择答案；第三项在重听一遍的同时,记下与广告不符的情况；第四、五项的听力重点在词汇上,练习的内容是完成所听的句子和填上所缺的词.所有读、听、说的活动层次清晰,内容连贯,实际上都在为完成下一步写的任务积累素材和提供示范.说话与写作的中心任务是本单元写作练习的主题：对某事或某人以礼貌的方式责备和抱怨.该部分提供了表示责备和抱怨的习惯用语和三种情境,要求学生运用所给的词语先进行对话

13、练习,然后再把对话内容写下来.这种写作练习设计能使学生体会到语言的鲜活、生动和实用,有利于发挥他们的写作积极性.2 教材重组2.1 Pre-reading, Reading, prehending是一个整体, 而第一部分Warming Up的话题内容又与Reading一致,因此将这几部分整合在一起,设计成一节阅读课.2.2 Learning about Language 中的两项活动和Workbook 中的USING WORDS AND EXPRESSIONS 以与USING STRUCTURES内容一致,整合起来设计成一节语言学习课.2.3 将Using Language 中的听力部分 与W

14、orkbook中的LISTENING, LISTENING TASK 整合为一节听力课；由于Workbook中TALKING 的任务是谈论前面两个听力内容的,所以将此项任务也加进这一课时.2.4 将Using Language 中的Reading and discussing 以与其后的四项练习与Workbook中的READING TASK 以与其后的两项练习整合在一起,上一节泛读课.2.5 将Using Language 中的Speaking and writing 与WRITING TASK, SPEAKING TASK 整合成一节交流写作课.注：本单元说的任务分别体现在听、写、读等各项活
