新人教选修8 Unit2 Cloning-Talking and writing课件 (1)
Sample speech:
Dear chairperson, ladies and gentlemen, It is my pleasure to present the arguments for those that want cloning research to continue. As you are already aware, cloning research is very important for curing serious illnesses.
For 2. to help people Medical who have diseases cloning which make them
gradually lose their ability to move easily or to think
Various answers and reasons are possible.
Some of these illnesses have no cure, some are to help people regain the use of their brain or movement. The advantages for the patient are tremendous. The disadvantages for the patient are small. Most people are in favour of medical cloning.
As she put it: "Who among us could tell a person suffering from cancer or Alzheimer's, 'you cannot have the cure that will save your life' ?" None of us, I am sure. So I hope after listening to all the arguments you too will be able to support medical cloning. Please vote for our side of the debate.
选修8_Unit2_Cloning(Reading)说课稿

首先,我对本节教材进行一些分析:一、教材分析(说教材);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。
本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。
教学目标: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。
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, fast reading ,careful reading等阅读技2.对文章深层次的理解及细节的欣赏,认识及了解克隆技难点: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。
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,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Listening 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,列举克隆利弊及分析作者对克隆的态度看法等。
