高二英语选修8 Unit2 Cloning(Reading) 说课稿各位老师好，今天我说课的内容是选修八第二单元Cloning的Reading部分。
首先,我对本节教材进行一些分析:一、教材分析(说教材)；1. 教材所处的地位和作用：本课是人教版新教材选修8 Unit2 Cloning(Reading)，本课的中心话题是克隆。
本文具体介绍了植物与动物克隆的区别、多丽羊的诞生与死亡及由此引发的争论。
帮助学生进一步认识克隆的意义在于解决医学上的难题，为人类服务。
本节课是这篇阅读的第一节课，目的旨在让学生读懂文章的意思、了解文章的内容、把握文章的中心。
从而提升自己的阅读能力，要让学生学习了解克隆这门技术以及有关的争议。
2、教学目标：1）语言知识目标：a）使学生会使用本单元的相关词汇讲述克隆的概念，以及克隆带来的问题，及表达自己对克隆的认识。
b）初步掌握本单元重点词汇：identical; straightforward; undertake sth; cast down 等。
2）语言技能目标：a)使学生学会克服生词障碍，通过略读，寻找文章的主题句，理清文章的总体框架与脉络；通过查读，捕捉文章的重要细节，理解作者的写作意图。
b) 使学生学会运用各种猜词技巧，猜测部分生词在具体的语言环境的含义3）情感态度与文化意识目标：通过对本文的学习，唤起学生对生活的关注，知道克隆的重要意义，以及克隆技术可能的利与弊，激发学生热爱科学的热情。
确立教学目标的依据：根据新课标要求，通过说、读、写等基本语言技能的训练，使学生形成综合语言运用能力，激发学生的学习兴趣，为真实语言交际打基础。
此外，每一门课程都应该尽可能结合学科特点，把培养学生的情感融化到日常教育教学中。
3、重点与难点：重点：1．了解科技说明文的文体特点并以此指导阅读；训练skimming, scanning, fastreading ,careful reading等阅读技巧2．对文章深层次的理解及细节的欣赏，认识及了解克隆技术。
难点：1.阅读技能的训练；2．对科技说明文的鉴赏能力及事物的客观评价。
4．教学辅助工具：（1）录音机；（2）多媒体二、说教法（教学策略）鉴于课文内容综合性强，新词多，阅读理解难度大等原因，于是通过小组合作学习方式读前利用一些克隆相关图片进行分类，使学生对克隆先有一个基本了解，从而自然地引入到课文并复习文中所含的新词语开始课文学习以便学生能较好地阅读理解。
作为阅读课，老师需以多种方法引导学生阅读，培养和提高他们有效完成各种阅读任务的技能。
所以，在本节Reading教学中贯穿Looking through,skimming和scanning等阅读方法逐层渐进式完成本Reading部分所要求完成的阅读任务：文章及各段的main idea,某些详细信息，回答问题，列举克隆利弊等。
最后，为扩展同学们关于克隆的思索，特设一个Discussion来加强他们对课文克隆内容的认知以活跃其辩解思维。
理论依据：从本质上讲，合作学习是一种教学形式。
他要求学生在一些几个人组成的异质性小组中一起从事学习活动，共同完成老师分配的学习任务。
在每个小组中学生们通常从事各种需要合作或互助的学习活动。
”学生们一起学习，获得知识，并且当他们获得成就时，他们变得非常投入，变得关心他人和他人的学习。
他们在一起进步的过程中，关心他人和他们的成就，结成紧密的学术关系和人际关系三、说学法阅读是一种积极主动地吸收、思考、理解、接受信息和反馈信息的过程，也是一种复杂的智力活动。
培养学生的阅读理解能力可分三个层次：表层理解、深层理解和评价性理解。
表层理解是培养学生对文章表面信息的把握，了解文章的大意；深层理解是引导学生通过联想、推理、归纳等思维活动对本文进行进一步的理解，掌握文章细节；而评价性理解建立在从整体角度对课文深层理解的基础上，旨在引导学生联系社会实际或自身生活，对克隆进行讨论，使学生进行发散性、创造性思维。
通过小组合作学习帮助学生提高阅读技能和技巧。
同时培养了学生的认知策略、交际策略、调控策略、资源策略四、教学流程：１、新课导入利用幻灯片展示当今克隆技术产生出来的一些关于克隆的图片让同学们进行讨论哪些是自然克隆哪些是人造克隆？（设计意图：通过师生互动，激活主题，激发了学生的学习兴趣，对后面进行本文的阅读做了铺垫和准备）2、阅读前思考引发学生对于克隆的思考，并列举出你想知道的问题1）．What is a clone?2）. How is a clone produced?3）. What benefits can humans gain from cloning?4）. What problems may arise when humans are cloned?（设计意图：通过思考这些问题培养学生预测课文的能力）3、阅读中活动:I. Skimming: Skim the following passage and get the main idea of the whole text The text is mainly about the 1. _________ of animal cloning and the life of Dolly the sheep, as well as the reasons why cloning is still 2. ____________. （设计意图：让学生快速浏览课文，培养学生学会快速捕捉文章表层信息的能力，从而进一步理解文章的中心内容。

）III. Mini-Debate: Is cloning people a good thing or a bad thing?Advantages Group 1 and 2Disadvantages Group 3 and 4（设计意图：培养学生口语及用英语思维的能力并形成自己的交际策略）IV.
