Unit 3 Under the seaPart 1 Teaching Design第一部分教学设计Period 2 A sample lesson plan for Learning about Language (Revise the Passive Voice <2>, including the –ing form) IntroductionIn this period students will be first helped by the teacher to discover and learn to use some useful words and collocations, and then revise the passive voice <2>, including the –ing form. The following steps of teaching may be taken: warming up by reading aloud the text Old Tom The Killer Whale, discovering useful words and collocations, learning about the Passive V oice <2>, including the –ing form, 学习多功能where的用法, closing down by revising some difficult uses of the passive voice.ObjectivesTo help students revise the Passive V oice <2>, including the –ing formTo help students discover and learn to use some useful words and collocationsTo help students discover and learn to use some useful structuresProcedures1. Warming up by reading aloud the text Old Tom The Killer Whale Language is learned in context. So let’s first review the text learned yesterday by reading it aloud. Try to force out your English slowly and clearly.2. Discovering useful words and collocationsIn pairs do the exercises 1 and 2 on pages 22. You must finish them in 5 minutes.3. Learning about the Passive Voice <2>, including the –ing formThe voice of a verb refers to the form of the verb used in relation to what the subject is doing. InEnglish there are only two voices—passive and active.The passive voice of a verb simply means the form of the verb used when the subject is being acted upon rather than doing something.The passive voice is formed by taking the appropriate tense of the verb to be and adding the past participle.Active Voice: The committee reviewed the project.Passive V oice: The project was reviewed by the committee.In most writing, use the active voice. It is more direct and less ambiguous.The passive should only be used if the doer is unknown or unimportant, or if more emphasis is put on the receiver of the action than the doer.Doer unknown: The Jones' car was stolen last week.Doer unimportant: The bells were rung to announce the wedding.Emphasize receiver: Tony was hit by a fastball.4. 学习多功能where的用法where在英语中可以引导多种从句，是一个具有多重功能的引导词。

Unit 3 Under the seaⅡ. 目标语言Ⅲ. 教材分析和教材重组1. 教材分析本单元以大自然中的海底世界为话题, 以谈论海底世界的动植物为切入点，让学生在交流中发现和理解大自然的奇妙和美丽；通过阅读奇闻故事，使学生从一个侧面理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使用已有的自然知识、亲自体验、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使用的过程中，深入学习、理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，从而在学习和使用语言的同时，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理解海底世界。
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。
这个局部的设计为下一步的课文学习以及后边的听、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。
“虎鲸协助捕鲸人在每年须鲸迁徙时捕捉须鲸”的奇闻轶事会立即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。
第一篇讲虎鲸如何协助捕鲸人捕捉须鲸，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协助和巨大的贡献，同时习得阅读故事的技能。
1.4 Comprehending设计了根据课文内容描绘Old Tom和捕鲸人的关系, 旨在引导学生在阅读理解的基础上实行再创造。
