研究性学习名称
1）从话题内容上分析，Warming Up 与Reading相一致；而从训练目的上分析与Talking比较一致。从教材份量来说，可将Warming Up和Reading整合在一起，设计成一节任务型“阅读课（精读课）”。 2）本课时为Reading部分，具体介绍了植物与动物克隆的区别，多利羊的诞生与死亡以及由此引发的争论。旨在通过单元教学，使学生了解克隆技术的优缺点，学会表达和支持个人观点，能用所学的有关Cloning的词汇去表述自己对这一新技术的观点和看法。
小组成员 高三·1班、2班全体同学 所需时间 1课时 【课题概述】 简介：本单元以Cloning为话题，克隆意为无性繁殖 ，克隆技术即无性繁殖技术。1997年英国罗斯林研究所实验成功的克隆羊多莉是首次利用体细胞克隆成功的，它在生物工程史上掀开了新的一页。本课时为Reading部分，具体介绍了植物与动物克隆的区别，多利羊的诞生与死亡以及由此引发的争论。旨在通过单元教学，使学生了解克隆技术的优缺点，学会表达和支持个人观点，能用所学的有关Cloning的词汇去表述自己对这一新技术的观点和看法。
【学情分析】 本节课的学习者特征分析主要是根据教师平时对学生的了解以及学生年龄段的思维发展情况而做出的： 1)学生是兖州一中高三年级的学生，有较强的求知欲和好奇心；对新教材有一定了解适应，自主学习习惯基本养成，对教师依赖性相对较低； 2)学生有较多的阅读探究及任务型学习的经验；学生能够运用阅读技巧解决课后的相关阅读理解问题； 3)学生在过去的生活经验中有与克隆Clone相关的知识储备；对新事物新技术有好奇心，思维活跃，但思考不够深入，逻辑性不强； 因此，在高中英语教学中，对学生的学习策略和人生意义指导比传授知识更重要。 “授人以鱼，仅供一饭之需；授人以渔，则终生受用无穷。”
【设计思想】 为了创造民主、和谐、开放的教学氛围，这节课本着以教师为主导、学生为主体、思维为主攻，训练为主线的思想，在师生互动的状态下完成教学任务。这样做即有利于培养 3
学生的阅读能力，也有利于教师及时得到教学信息的反馈、及时调节改进教学策略。 【教学目标】 （一）知识目标 1) 学会使用本单元的重点词语和表达，如：clone，commercial，producer，undertake，arbitrary，object，forbid，accumulate，cast down，object to，the media，in favour of等 2）使学生了解克隆技术的优缺点，学会表达和支持个人观点 （二）能力目标 1）理解篇章结构，归纳文章主旨和段落大意。 2）掌握提取信息（skimming, scanning, &summarizing），分析信息，解决问题的能力。 3）使学生了解克隆技术的优缺点，学会表达和支持个人观点，能用所学的有关Cloning的词汇去表述自己对这一新技术的观点和看法。 （三）情感态度 通过对是否克隆人的辩论，让学生正确认识克隆技术，树立正确的价值取向，热爱和平，反对暴力。 【教学重点、难点】 教学重点： 本课时为阅读文章即reading部分，阅读量正常，难易度适中，因此将重点放在对文章的理解上，特别是在阅读中，如何提高获取信息，分析信息，解决信息背后的意义上。 教学难点： 1. 如何调动学生积极性，表达自我想法，列举事例，支持自己的观点。 2. 掌握课文的主旨大意，整理出关于课文结构的主要信息 3. 使学生了解克隆技术的优缺点，学会表达和支持个人观点，能用所学的有关Cloning的词汇去表述自己对这一新技术的观点和看法。 【教法学法】 1. 教学方法： 由于学生对本文话题有浓厚的兴趣，所以，以精心设计的问题由浅入深地引导学生自 己去分析、讨论、归纳总结。因此，本节课的教学思想，是以“教师为主导，学生为 主体，思维为主攻，训练为主线” 。在师生互动的状态下完成教学任务。 2. 学习方法：研讨归纳法 通过系统、理论的阅读方法指导，学生利用“快读、精读、跳读、略读”等技巧；以 个体思维、小组讨论等形式探讨、总结归纳。充分调动了学生的积极性，激发了学生 的求知欲。 4
3. 教学手段： 本节课采用白板教学，采用音乐、图片、视频与文字相结合的方式，既增加课堂的信 息量，又调动学生的学习兴趣，并能在解决重点、突破难点方面起到辅助作用 设计依据：现代英语教学强调在“用中学”，因此创设语言环境对语言习得起着重要的作用。同时，通过电脑课件展示相关的图片，视频，或静态，或动态，以直观的效果激发学生固有的背景知识，在学生固有的背景知识和文本信息之间搭建起理解桥梁，能有效地帮助他们获取信息，达到理解信息的目的。 【教学过程】 教学过程设计 读前（3’）： 了解相关知识 共分三部分： 掌握主旨和段落大意（略读和寻读） 读中（30’） 获取特定信息（细读） 积累运用（巩固） 读后（12’）：知识迁移 Step1 Lead- in
1) 在课前播放一段克隆羊多利出生的视频，问学生
1.Dolly was a ______ sheep. 2. When was the cloning of Dolly the sheep born? 由此引出克隆这个话题。 2）展示Dolly the sheep(多莉羊)、 A strawberry plant(草莓植物)、 Twins（双胞胎婴儿）的图片，让学生讨论并说出它们之间的不同点。 which ones are natural clones and which ones are man – made? S: I think the twins are natural clones and the Dolly sheep is man-made. T: You are right! Can you explain how they differ? S: The twins were born at the same time, but the Dolly sheep is man-made. 【设计说明】克隆技术是一门前沿科技，学生对此兴趣浓厚，利用视频和幻灯片展示当今克隆技术产生出来的动植物照片，学生的兴趣被瞬间激发，注意力高度集中，学习的热情高涨。这就为进一步的学习做足了铺垫。 Step2 Fast reading Give the students 3’ to read the whole text silently and finish the two tasks 1. What’s the passage mainly about? 2. According to the main idea, divide the whole text into 4 parts. 5
【设计说明】给学生3’快速浏览课文，归纳文章主旨大意和分段，主要培养学生运用阅读方法的技能(skimming)以及概括归纳(summarizing)的能力。 课堂过渡句：Now that you have known the main idea of the whole test and each paragraph, let’s come to the careful reading to know the detailed information. Step3 Careful reading 1) Paragraph 1 Ask all the students to Listen to the first paragraph and fill in the blanks. Cloning is a ______ of making an exact _______ of another animal and plant. It happens both in ______ and in_______. 【设计说明】让学生听录音第一段，听录音的过程有两个目的，一是帮助学生正音， 二是再次理解文章，有助于活跃课堂气氛，放松学生心情，这个填空题有关克隆的定义并不难，学生可以直接在文章找出答案。 课堂过渡句：So we know the definition of cloning. Do you want to know the major uses and
procedures of cloning? Now let’s come to Paragraph2. 2) Paragraph 2 1) Read Paragraph 2 aloud, and then answer the question: How many major uses do
cloning have? 2) Recite the answer.
设计意图：1)克隆是一项新技术，虽说学生感兴趣，也有一定的了解但是没有上升到理论的高度，设计这个问题有助于学生了解克隆技术的应用和潜在前景，拓宽知识面。问题不是太难，学生可以从文中直接找到答案。 2）要求学生背诵答案，为之后的讨论做好知识储备。 课堂过渡句：Now you have known the uses of cloning, do you want to know what effect it has used? The first cloned sheep Dolly is well or poor? The answer is in the 3rd paragraph. 由提问多利羊的身体状况来自然而然地过渡到了第三段 3) Paragraph3 The problems of Dolly 1） Read Paragraph 3 aloud,and then finish the blanks. 2） Try to trcite them. At first, the fact that Dolly developed ______ in a natural way was __________. Later, the news _____she lived for six years, half the length of the life of the ______ one was __________. Finally, the problem that occurred to the scientists was that a cloned animal lives _____________ the original one.

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。

So teacher should help the students learn more about it. Do this in the way of asking and answering questions.T: You can imagine how rapidly the modern 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. It sounds very different and complicated to us. In fact，I mean，in our daily life，this happens often. For example，gardeners take cuttings fromgrowing 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 the same original egg. The fact is that cloning plants is straightforward but the cloning of animals is more complicated. The possibility of human cloning，raised when Scottish scientists at Roslin Institute created the much-celebrated sheep "Dolly"，aroused worldwide interest and concern because of its scientific and ethical implications. You can give your questions if you are interested in this topic. I am here today one of the scientists who work in this field. I am ready to answer any of your questions.S: Now we know what is cloning. Are there different types of cloning？T: When the media report on cloning in the news，they are usually talking about only one type called reproductive cloning. There are different types of cloning however，and cloning technologies can be used for other purposes besides producing the genetic twin of another organism. A basic understanding of the different types of cloning is key to taking an informed stance on current public policy issues and making the best possible personal decisions. The following three types of cloning technologies will be discussed: (1) recombinant DNA technology or DNA cloning，(2) reproductive cloning，and (3) therapeutic cloning.S: Was Dolly created by what cloning？And why was Dolly so important？T: Reproductive cloning is a technology used to generate an animal that has the same nuclear DNA as another currently or previously existing animal. Dolly was created by reproductive cloning technology. She was the first mammal to be cloned from adult DNA taken from an adult cell. Previously，animals had only been cloned using embryo cells which already have the potential to become a complete embryo in its own right. The big breakthrough with Dolly was to make a clone from an ordinary，adult cell − in this case from a female goat’s udder.S: Have you seen Jurassic Park？In this feature film，scientists use DNA preserved for tens of millions of years to clone dinosaurs. They find trouble，however，when they realize that the cloned creatures are smarter and fiercer than expected. Could we really clone dinosaurs.T: In theory？Yes. What would you need to do this？A well-preserved source of DNA from the extinct dinosaur，and a could serve as a surrogate mother. In reality？Probably not. It’s not likely that dinosaur DNA could survive undamaged for such a long time. However，scientistshave tried to clone species that became extinct more recently，using DNA from well-preserved tissue samples.More questions about cloning are given in the appendix. The information above is for reference only. Or you can choose several students and ask them to act out a short play whose main topic is as follows:An old man who was dying left all his fortune to his own son. But they did not know that his son was cloned. So two same young men both claimed that they were the old man’s son. They quarreled and fought with each other；at last they went to the judge. The judge let them check DNA. The result was that their DNA was the same. Now even the judge did not know what to do. In this part the teacher can give the students some advice to act out. According to this play teacher ask the students several questions:1. Do you want to be cloned or not？Why？2. If you are the judge what will you do？3. Can you tell me the advantages of cloning？4. And what is the disadvantage？DiscussionIn this part the students will discuss the relationship between the development of technology and social customs.T: As the technology develops day by day，it has a more and more important influence on the whole society. Technology affects social customs and ethics，sometimes technology may go against the conventional thinking，then comes the problem that whether we should stop the development of research or change the ethics.S1: As technology develops in almost every field，a lot of our original customs and ethics changed，either because they are out of time or not so scientific. For example millions of years ago human ate meat of animals without heating them. Later people used fire and no longer ate raw meat and they also used fire to scare dangerous animals.S2: I think we could not stop the development of technology，for it may develop in the way which is acceptable by social customs.…Look at picturesT: Look at the pictures and discuss which ones are natural clones and which ones are man – made. Then explain how they differ.S: I think the twins are natural clones and the Dolly sheep is man-made.T: You are right！Can you explain how they differ？S: The twins were born at the same time，but the Dolly sheep is man-made.T: Anything else？Who want have a try？S: I think the identical dog is man-made.T: Good JobStep II Pre-readingBefore 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.T: Now please work in pairs and discuss about cloning. Then list the questions you want to find out. Share your list with your partner.Ss: Yes，sir / madam.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？(After a few minutes.)T: Do you have other questions？V olunteer！S: I have！What is the writer’s opinion？T: Good job！I think many of you have questions，now let us read the article with the questions.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. It also 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 While- readingGet the students to comprehend the passage quickly and accurately and meanwhile help the students form a good habit of reading.T: Have 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 Post-readingAsk the students to read the passage again to finish three tasks.T: Now let’s listen to them. While listening，pay more attention to the correct pronunciation and tone. Then read the text by yourselves to get the answers to the three tasks. You can work in groups.T: First，What are the problems or dangers of cloning？S: Let me have a try！First，the cloned animals have the same illness of old animals and the same goes with the other species. Second，the cloned animals have short life and can cause moral questions.T: You are right！And what are the advantages of cloning？S: I know！Firstly，gardeners use it all the time to produce commercial quantities of plants. Secondly，it is valuable for research on new plant species and for medical research on animals. Thirdly，it suddenly opens everyone’s eyes to the possibility of using cloning to cure serious illnesses，and even producing human beings.T: What is the writer’s opinion？What do you think is the writer’s point of view in this reading passage？Is it in favor of cloning or against is？S1: I think the writer is in favor of it，because there are many advantages of cloning. It can help people solve many problems in our daily life.S2: I think the writer doesn’t agree with it，because if the cloning technology can be used in an evil way，it can cause much trouble to our society.T: The next question: What is your opinion of cloning？Give the reasons.S1: As a coin has two sides，everything has two aspects. First，if the cloning is used in a correct way it can bring many conveniences to us. Such as: curing serious illnesses and being used to produce commercial qualities of plants. On the other hand，if the cloning is used in an evil way it can cause much troubles: such as moral questions.S2: My view on cloning and nuclear transfer is that it is ethical. So actually I find no reason to clone presently. I have this opinion currently，because scientists are unable to successfully clone using nuclear transfer as of today.S3: I also have a problem with the possible effects of using nuclear transfer on a large scale. This is because I fear that cloning could greatly reduce genetic diversity. I believe if we were to interfere with the genetic diversity of an entire population we would undoubtedly fail.S4: As you can see I believe cloning using nuclear transfer should not be used on humans for any reason. I think if we were to use cloning it should be closely monitored as to what dangers are involved in having copies of people. I also think this technology should not be used until success. S5: I agree that we should develop cloning. I’m not afraid of cloning Hitler or excited t o clone Einstein. I would say the time and the environment produced Hitler，not his DNA. So you do not need DNA from Hitler to produce a Hitler. In fact，there are Nazis already present. We should make use of cloning to benefit future generations. You can imagine that how happy the people are if they can recover from the serious illness or get back the son who has just lost his life in an accident by cloning.T: Good job！Yes，if we our human beings use the scientific technology properly it can bring many advantages to us！S: Why did Dolly’s appearance raise a storm of objections and have a great impact on the media and public imagination？T: Because nothing really prepared the world for the 1997 announcement that a group of Scottish scientists had created a cloned sheep named Dolly. Many folks believe that within the next decade，we will hear a more shocking announcement of the first cloned human. Scientists in South Korea have already created human embryonic stem cells through cloning. Until now，the idea of human cloning has only been possible through movie magic，but the natural progression of science is making human cloning a true possibility. We’ve cloned sheep，mice and cows，so why not humans？Some countries have set up laws banning cloning，but it is still legal in many countries. Imagine using a piece of your great-grandmother. This opens the door to many ethical problems，but it’s a door that could soon be opened.S: So what happens next？T: Whatever the reasons，the new cloning technologies have sparked many ethical debates among scientists，politicians and the general public. Several governments have considered or enacted legislation to slow down，limit or ban cloning experiments outright. It is clear that cloning will be a part of our lives in the future，but the course of this technology has yet to be determined. Cloning could cause birth defects，but it’s not going to change society. In the absence of any legislation or regulation，cloning attempts will quietly continue. Eventually，cloning will s ucceed (if it hasn’t happened already)，and humankind will have taken another step down the road of biological engineering. You should study hard today，and you will be able to face this difficult problem and know how to deal with it.ExplanationT: Now le t’s deal with some language points. Turn to page 11. Let’s look at the sentence: 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。

Ability goalsEnable the students to express their opinions about cloning using some useful expressions.3. Learning ability goalsHelp the students learn how to express their opinions.Teaching important pointsLearn to use the structures of expressing and supporting an opinion.Teaching difficult pointsHow to give a speech.Teaching methodsCooperative learning.Teaching aidsA computer & a projector.Teaching procedures & waysStep Ⅰ Lead-inT: Good morning / afternoon, boys and girls!Ss: Morning Mr...T: Last class we have talked about clone, we all know it is not a dream. Now everyone, if I give you a chance to clone what will you restore then?S: Edison, dinosaurs, Japanese wolf, Einstein.T: Do you want to clone Hitler?S: No. Hitler is a dangerous person.T: If some terrorists master this clone method, they may bring disasters. All your choices are excellent. Today we will learn another passage about cloning, from which we will know whether we can bring dinosaurs back to life.Ask the students to go through some facts of cloning.T: From these facts we know human beings have achieved great progress in cloning. Now read the text carefully to get the answers for these questions: what animals have people cloned?S: Frogs, mice, cows, sheep, bisons, cats, and dogs.T: Good job. Answer the question: What are the common characteristics of these animals?Ss: They are nowadays animals.T: Yeah, I think you must have seen the film Jurassic Park, in which a scientist clones several different kinds of extinct dinosaurs. Can we really clone dinosaurs now?Let the students turn to page 15 and then read the text quickly. Several minutes later. S: We cannot clone dinosaurs, because it’s difficult for us to get its DNA.T: Good job. It’s only a dream. Dinosaurs disappeared 65,000,000 year s ago. So the chance of dinosaurs ever returning to the earth is merely a dream.Step Ⅱ Read and answer (P16)To answer these three questions, teacher can give the students some examples as explanation, for example, Question 1.T: Now think about this question: if in the world there is only one sheep and human beings want to clone more. Some days later a Dolly appears, then many more. But one day all sheep get the same deadly disease. Now please think about what the results are. S: Maybe they would all die.T: Why?S: Because all sheep have the same arrangement of genes.T: Right. Now ca n you answer Question 1? Why shouldn’t you clone an extinct animal unless there is enough diversity in the group?S: It is useless to clone an animal if there is not enough diversity in the group for it to overcome illnesses.T: Why is it wrong to clone an extinct animal if it would have to live in a zoo?S: If the cloned animals have to live in the zoo, it is unfair to them. They need freedom.T. Why can’t you clone the DNA of animals that have been extinct longer than 10,000 years?S: Dinosaurs disappeared 65,000,000 yeas ago. So the chance of dinosaurs returning to the earth is merely a dream.Step Ⅲ Discussion (Question 2)This is a speaking task. Ask the students to have a discussion in groups, organize theirwords properly, and give vivid description of the chosen animals.T: Now look at the table on page 16, discuss in pairs which extinct animals described are worth restoring by means of cloning. Choose one animal and use the information to help you argue why this animal should be restored to the earth.Give the students six minutes to discuss.S1: I think Great Auk is a wonder. Because it is a very large bird that cannot fly. The useful thing about it is that its feather doesn’t absorb water. I think if we wear clothes made of its feather, we will not worry about rain.S2: I agree with you. But I am happy to accept Dodo bird because it is friendly and not harmful. I like gentle animals. It can also lay large eggs and its meat is tasty, but I don’t think I will eat its meat.…T: From your answers I think these animals are all useful and they all should be restored to the earth. At the same time, we should try our best to protect them. Do you agree with me?S: Yes.Step Ⅳ Writing a report (P17)Deal with Questions three and four. Divide the whole class into four groups. Then they can have a competition.T: Now everyone, imagine all of you are owners of your chosen animal. Now work together, and give us a vivid description of your pet, then I will decide which one is the best to be resorted to the earth.Several minutes later, the students give performances. At the same time, list some major points on the blackboard.T: Well done everyone. It is really hard for me to choose, let us vote OK?Step Ⅴ TALKING (P55)Ask the students to talk about the questions with the teacher’s help.T: Look at the questions on page 54. Do you know how to show your opinion? You can discuss the following questions with your partner and use these expressions on page 54.1. How would you feel about having a clone of yourself in the family?2. What problems did you have growing up and how can you help him / her avoid them.HomeworkT: Write down your feelings and attitudes towards clone. Combine them into a composition.Sample version 1:In my opinion it is wrong to clone human beings. If my parents decide to have a clone made of me, I will feel very sad and I will never accept the clone as a member of my family or as my friend because I think it is unfair to natural things.We are all sons of nature, birth or death is a natural thing. The day we born, itdestined we are independent. Nobody has the right to change ourselves. If one day I were to be cloned to another person, he would kill me, because I lost some original characters. I hope we should respect human beings, and not change any original things.Sample version 2:I think the cloning represents the progress of the mankind. But it still has many problems to work out, the law, the ethic and especially the goals and purposes for cloning. However, we are actually doing much of this research for the improvement of life for humans. We should get benefit from cloning.In China, the government has put out written policy on human cloning. It has officially banned research on human cloning for reproduction purposes, but allows cloning on embryonic stem cells and remedial cloning. As we all known, everything can’t be perfect. We should treat the cloning with correct attitudes. We should know the advantages and disadvantages of cloning.。

Unit 2 Cloning 教学设计3-公开课-优质课(人教选修8精品)
Unit 2 Cloning 教学案3I.背景阅读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. It sounds very different and complicated to us.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 the same original egg. The fact is that cloning plants is straightforward but the cloning of animals is more complicated.The possibility of human cloning，raised when Scottish scientists at Roslin Institute created the much-celebrated sheep "Dolly"，aroused worldwide interest and concern because of its scientific and ethical implications. She was the first mammal to be cloned from adult DNA taken from an adult cell. Previously，animals had only been cloned using embryo cells which already have the potential to become a complete embryo in its own right. The big breakthrough with Dolly was to make a clone from an ordinary，adult cell − in this case from a female goat‟s udder.1. Fill in the blanks according to the passage.1) The definition of cloningCloning is a ________ of producing a genetically identical duplicate of an animal or a plant. It happens both in ______ and in_______. They can be cloned by _______ or humans. The former is_______clone while the latter is man-made clone.2) How does Dolly differ from other sheep？She was ______ by humans while the others were born naturally.So，Dolly was a ______ sheep.2. Discuss the following questions.1). Can you see any cloning happen in our daily life？2). What benefits can humans gain from cloning？3). What problems may arise when humans are cloned？4). Should we clone a human？5). Could cloning replace sex as the means of creating new human life？6). Could a parent clone a child who is dying of a terminal illness？ReadingI. Reading comprehension:1. The main idea of the text is____A. animal cloning is very valuable and can benefit the world.B. animal cloning could be misused by bad people so it must be forbidden.C. animal cloning is well developed because Dolly the sheep was born.D. animal cloning raised arguments and scientists are not sure about its future.2.The cloning of Dolly the sheep succeeded because____.A. it‟s easier to clone a sheep than other animalsB. the scientists were determined and worked hard with patienceC. the scientists were rewarded and got lots of moneyD. many other attempts to clone mammals failed3. What is the writer‟s attitud e toward cloning in this passage？A. The writer is against cloning.B. The writer is in favor of cloning.C. The writer is neutral towards cloning.D. The writer is in agreement with cloning.4. Which of the following is not an advantage of cloning？A. Cloning can be used for medical purposes.B. Large quantities of food can be produced by cloning.C. Cloning can help keep animals from becoming extinct.D. People can clone themselves at will.5. We can infer from the last three paragraphs that ___.A. The normal development of Dolly had no effect on the cloning of other species.B. Dolly‟s serious disease and final death disturbed the whole world.C. Dolly successfully cloned a new lamb with the help of cloning scientists.D. There were arguments about animals about animal cloning and concerns about the future of cloning.6.What is the writing style？A. Expositive (说明性的)B. DescriptiveC. Argumentative (议论性的)D. NarrativeII. Fast reading: True or False questions1. Cloning means making a copy of an animal or a plant.2. Gardeners can make a lot of money by cloning plants.3. Cloning animals is as complicated as cloning plants.4. Dolly the sheep was the first successful clone of a mammal.5. Natural clones happen in animals as well as in plants.III.

Ability goalsEnable the students to describe cloning: What is the advantages of cloning？What is the problems or dangers of cloning？What is your opinion of cloning？3. Learning ability goalsHelp the students learn how to describe cloning.Teaching important pointsHow to describe cloning.Teaching difficult pointsHelp the students analyze the writing techniques of the article.Teaching methodsSkimming, task-based method and debate method.Teaching aidsA recorder, a projector and some slides.Teaching procedures && waysStep I Lead-inThis topic is difficult for students. So teacher should help the students learn more about it. Do this in the way of asking and answering questions.T: You can imagine how rapidly the modern 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 thing 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. It sounds very different andcomplicated to us. In fact, I mean, 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 the same original egg. The fact is that cloning plants is straightforward but the cloning of animals is more complicated. The possibility of human cloning, raised when Scottish scientists at Roslin Institute created the much-celebrated sheep “Dolly”, aroused worldwide interest and concern because of its scientific and ethical implications. You can give your questions if you are interested in this topic. I am here today one of the scientists who work in this field. I am ready to answer any of your questions.S: Now we know what is cloning. Are there different types of cloning?T: When the media report on cloning in the news, they are usually talking about only one type called reproductive cloning. There are different types of cloning however, and cloning technologies can be used for other purposes besides producing the genetic twin of another organism. A basic understanding of the different types of cloning is key to taking an informed stance on current public policy issues and making the best possible personal decisions. The following three types of cloning technologies will be discussed: (1) recombinant DNA technology or DNA cloning, (2) reproductive cloning, and (3) therapeutic cloning.S: Was Dolly created by what cloning? And why was Dolly so important?T: Reproductive cloning is a technology used to generate an animal that has the same nuclear DNA as another currently or previously existing animal. Dolly was created by reproductive cloning technology. She was the first mammal to be cloned from adult DNA taken from an adult cell. Previously, animals had only been cloned using embryo cells which already have the potential to become a complete embryo in its own right. The big breakthrough with Dolly was to make a clone from an ordinary, adult cell —in this case from a female goat’s udder.S: Have you seen Jurassic Park? In this feature film, scientists use DNA preserved for tens of millions of years to clone dinosaurs. They find trouble, however, when they realize that the cloned creatures are smarter and fiercer than expected. Could we really clone dinosaurs?T: In theory? Yes. What would you need to do this? A well-preserved source of DNA from the extinct dinosaur, and a closely related species, currently living, that could serve as a surrogate mother. In reality? Probably not. It’s not likely that dinosaur DNA could survive undamaged for such a long time. However, scientists have tried to clone species that became extinct more recently, using DNA from well-preserved tissue samples.More questions about cloning are given in the appendix. The information above is for reference only. Or you can choose several students and ask them to act out a short play whose main topic is as follows:An old man who was dying left all his fortune to his own son. But he did not know that his son was cloned. So two same young men both claimed that they were the old man’s son. They quarreled and fought with each other; at last they went to the judge.The judge let them check DNA. The result was that their DNA was the same. Now even the judge did not know what to do.In this part the teacher can give the students some advice to act out. According to this play teacher ask the students several questions:1. Do you want to be cloned or not? Why?2. If you are the judge what will you do?3. Can you tell me the advantages of cloning?4. And what is the disadvantage?DiscussionIn this part the students will discuss the relationship between the development of technology and social customs.T: As the technology develops day by day, it has a more and more important influence on the whole society. Technology affects social customs and ethics, sometimes technology may go against the conventional thinking, then comes the problem that whether we should stop the development of research or change the ethics.S1: As technology develops in almost every field, a lot of our original customs and ethics changed, either because they are out of time or not so scientific. For example millions of years ago human ate meat of animals without heating them. Later people used fire and no longer ate raw meat and they also used fire to scare dangerous animals.S2: I think we could not stop the development of technology, for it may develop in the way which is acceptable by social customs.…Look at picturesT: Look at the pictures and discuss which ones are natural clones and which ones are man-made. Then explain how they differ.S: I think the twins are natural clones and the Dolly sheep is man-made.T: You are right! Can you explain how they differ?S: The twins were born at the same time, but the Dolly sheep is man-made.T: Anything else? Who want have a try?S: I think the identical dog is man-made.T: Good job!Step Ⅱ Pre-readingBefore 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.T: Now please work in pairs and discuss about cloning. Then list the questions you want to find out. Share your list with your partner.Ss: Yes, sir / madam.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?After a few minutes.T: Do you have other questions? V olunteer!S: I have! What is the writer’s o pinion?T: Good job! I think many of you have questions, now let us read the article with the questions.Suggest 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. It also 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 hig her than his parents.7. No. The cloned baby also has the disease.Step Ⅲ While-readingGet the students to comprehend the passage quickly and accurately and meanwhile help the students form a good habit of reading.T: Have you got the answers of your questions? Now please skim the passage fast to obtain a general understanding of the whole passage. While reading, divide 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 Post-readingAsk the students to read the passage again to finish three tasks.T: Now let’s listen to the tape. While listening, pay more attention to the correct pronunciation and tone. Then read the text by yourselves to get the answers to the three tasks. You can work in groups.T: First, what are the problems or dangers of cloning?S: Let me have a try! First, the cloned animals have the same illness of the old animals and the same goes with the other species. Second, the cloned animals have short life and can cause moral questions.T: You are right! And what are the advantages of cloning?S: I know! Firstly, gardeners use it all the time to produce commercial quantities of plants.Secondly, it is valuable for research on new plant species and for medical research on animals. Thirdly, it suddenly opens everyone’s eyes to the possibility of using cloning to cure serious illnesses, and even producing human beings.T: What is the writer’s opinion? What do you think is the writer’s point of view in t his reading passage? Is it in favour of cloning or against it?S1: I think the writer is in favour of it, because there are many advantages of cloning. It can help people solve many problems in our daily life.S2: I think the writer doesn’t agree with it, because if the cloning technology can be used in an evil way, it can cause much trouble to our society.T: The next question: What is your opinion of cloning? Give the reasons.S1: As a coin has two sides, everything has two aspects. First, if the cloning is used in a correct way it can bring many conveniences to us. Such as: curing serious illnesses and being used to produce commercial qualities of plants. On the other hand, if the cloning is used in an evil way it can cause much troubles: such as moral questions.S2: My view on cloning and nuclear transfer is that it is ethical. So actually I find no reason to clone presently. I have this opinion currently, because scientists are unable to successfully clone using nuclear transfer as of today.S3: I also have a problem with the possible effects of using nuclear transfer on a large scale. This is because I fear that cloning could greatly reduce genetic diversity. I believe if we were to interfere with the genetic diversity of an entire population we would undoubtedly fail.S4: As you can see I believe cloning using nuclear transfer should not be used on humans for any reason. I think if we were to use cloning it should be closely monitored as to what dangers are involved in having copies of people. I also think this technology should not be used until success.S5: I agree that we should develop cloning. I’m not afraid of cloning Hitlers or excited to clone Einsteins. I would say the time and the environment produced Hitler, not his DNA. So you do not need DNA from Hitler to produce a Hitler. In fact, there are Nazis already present. We should make use of cloning to benefit future generations. You can imagine that how happy the people are if they can recover from the serious illness or get back the son who has just lost his life in an accident by cloning.T: Good job! Yes, if we our human beings use the scientific technology properly it can bring many advantages to us!S: Why did Dolly’s appearance raise a storm of objections and have a great impact on the media and public imagination?T: Because nothing really prepared the world for the 1997 announcement that a group of Scottish scientists had created a cloned sheep named Dolly. Many folks believe that within the next decade, we will hear a more shocking announcement of the first cloned human. Scientists in South Korea have already created human embryonic stem cells through cloning. Until now, the idea of human cloning has only been possible through movie magic, but the natural progression of science is making human cloninga true possibility. We’ve cloned sheep, mice and cows, so why not humans? Some countries have set up laws banning cloning, but it is still legal in many countries. Imagine using a piece of your great-grandmother’s DNA to create a clone of he r. In a sense, you could be the parent of your great-grandmother. This opens the door to many ethical problems, but it’s a door that could soon be opened.S: So what happens next?T: Whatever the reasons, the new cloning technologies have sparked many ethical debates among scientists, politicians and the general public. Several governments have considered or enacted legislation to slow down, limit or ban cloning experiments outright. It is clear that cloning will be a part of our lives in the future, but the course of this technology has yet to be determined. Cloning could cause birth defects, but it’s not going to change society. In the absence of any legislation or regulation, cloning attempts will quietly continue. Eventually, cloning will succeed (if it hasn’t happened already), and humankind will have taken another step down the road of biological engineering. You young students are the future of the world. You should study hard today, and you will be able to face this difficult problem and know how to deal with it. ExplanationHomeworkAsk the students to do the following.1. Complete the exercises on page 13.2. Recite the key sentences in the text.3. What is Clone? You might not believe it, but there are human clones among us right now.Have you ever wished you could have a clone of yourself to do homework while you hit the skate park or went out with your friends? Imagine if you could really do that. Where would you start?。
选修8 Unit2 Cloning
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。
