Unit 2 CtoningThe First Period Warming up and Reading Teaching goals1.Enable the students to describe cloning: What is theadvantages of cloning?2.Help the students analyze the writing techniques of thearticle.Teaching procedures Step I Warming up一：You can imagine how rapidly the modem science and technology develop. I think most of you must know something about space traveling, submarine exploration, robot, maglev train, gene engineering etc. But in recent years, a hot topic, cloning is often mentioned, especially when the cloning Dolly the sheep appeared. You may have first heard of cloning when Dolly the Sheep showed up on the scene in 1997. Cloning technologies have been around for much longer than Dolly, though.First things first, what is cloning and a clone? The dictionary says cloning is the technique of producing a genetically identical duplicate of an organism. A clone is said to be all descendants derived asexually from a single individual, as by cuttings, bulbs, by fission, by mitosis, or by parthenogenesis reproduction. In fact, in our daily life, this happens often. For example, gardeners take cuttings from growing plants to make new ones. You often see that your mother picks a small branch from a growing plant to make a new one. If she likes this kind of flowers, she can do cloning. Cloning also happens in animals or human beings when twins identical in sex and appearance are produced from thesame original egg.Discussion 1. Do you want to be cloned or not? Why?2.Can you tell me the advantages of cloning?3.And what is the disadvantage?二:Look at picturesLook at the pictures and discuss which ones are natural clones and which ones are man 一made. Then explain how they differ.Step II Pre-reading(Before class, ask the students to search for some information about this topic. ) Now show your questions on the screen, and then let them discuss with each other.Now please work in pairs and discuss about cloning. Then list the questions you want to find out. Share your list with your partner.Questions about cloning: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?5.Should we clone human?6.Could cloning replace sex as the means of creating new human life?7.Could a parent clone a child who is dying of a terminal illness?Suggested answers:1.It is a way of making an exact copy of another animal and plant.2.This happens in plants when gardeners take cuttings from growing plants to make new ones, and when small parts of a plant are taken and gown in a laboratory. Italso happens in animals when twins identical in sex and appearance are produced from the same original egg.3.It can help cure disease and can help couples who have no baby to bear a new baby.4.There may be more bad people like Hitler.5.In my opinion, I do not agree, for it may cause many moral problems.6.No. Because cloned human has the same quality as the real human, natural born baby's quality is higher than his parents.7.No. The cloned baby also has the disease.Step III Fast- readingHave you not the answers of your questions? Now please skim the passage fast to obtain a general understanding of the whole passage into several parts and find out the main idea of each part.Show the following.Para. 1 Cloning is a way of making an exact copy of another animal and plant.Para. 2 Cloning has two major uses.Para. 3 The problems of Dolly.Para. 4 The effect of Dolly.Para. 5 It is forbidden to clone human being.Step IV Careful-reading1.Ask the students to read the passage carefully to finish exercise Ion page 12 in the students, book.2.Check the answers.3.Finish exercise2on page 12 in the students' book.4.Check the answers5.Explanationl.)It is a way of making an exact copy of another animal and plant.全句汉语意思:它是一种精确复制另一个动物或植物的方式。

选修8 Unit2 CloningUsing Language说课稿本节课是选修8教材中第二单元语言运用部分，侧重于提高学生读、听、说的语言运用能力，同时培养学生在活动中相互学习、相互帮助的意识，发展学生英语学习的合作精神。

一、教学目标的设计1、通过阅读，让学生用材料中的句型、短语、词汇来加深对克隆技术的了解。

2、通过听力，让学生借助原有的听力基础和本课新学的知识来试谈对克隆动物的看法，即克隆的优点和不足。

3、通过说的活动，让学生进一步提高用英语来表达对克隆的认识，即克隆与生活、克隆与自我的关系。

二、文本解读第一部分：阅读材料。

通过一篇有关“克隆羊多利”的文章，讲述人类动物克隆研究，让学生通过阅读了解克隆。

首先通过阅读明确文章的观点，然后通过再次阅读让学生明白不能克隆的原因。

第二部分：听的材料。

让学生听一段关于克隆是否是对动物残忍的对话，首先进行听前预测，接着听大意，然后听细节，最后展开讨论，让学生发表自己的看法。

这项活动不但有利于提高学生的听说能力，而且能开发他们对克隆动物健康的关注及对克隆技术发展前景的再思考，具有现实意义。

第三部分：说的材料。

以“你最想克隆什么东西”问题展开，旨在发挥学生的想象力，然后通过“你想克隆一个与你一样的人吗？”这样的问题让学生各抒己见，增加学生的语言输出量，增强课堂的趣味性。

最后把这一部分作为一篇课后写作加以落实，提高学生的语言综合运用能力。

三、关于选修课的设计根据《高中英语课程标准》，选修课的设计应以课程目标和学生的需求为依据，要充分考虑学生的学习现状，既要有新内容、新发展，又不能超出学生的实际水平。

教师要引导学生主动学习，帮助他们形成以能力发展为母的学习方式，鼓励学生通过体验、实践、讨论、合作和探究等方式，发展学生的听说读写的综合语言技能。

四、课后反思对自己在课堂上未能充分调动学生的积极性而感到遗憾，课堂气氛不够热烈，主动发言的学生较少，还需更多考虑课堂指令的明确性。
