So teacher should help the students learn more about it. Do this in the way of asking and answering questions.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.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 the 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.a lot of our original customs and ethics changed, either because they are out of time or not so scie …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.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.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? Volunteer!Step 3.

2022-2021学年高中英语同步教案（4：Unit 2 Cloning人教新课标选修8）The first PeriodStep ⅠRevisionCheck the students’ homework.T: Last class we talked something about cloning. Now, who can show your opinion?S: Let me have a try. In my opinion it is wrong to clone human beings. If my parents decided to have a clone made of me, I would feel very sad and I would never accept the clone as a member of the family or as my friend.T: Good job!Step ⅡWord StudyT: You know it is not enough to recite words. You should also use it often. You must pay more attention to the tenses and voices. For example: The building was restored last year. In this sentence, you must use the words “was” and “restored”. Because the past tense and passive voice are contained in the sentence. Do you understand?S: How can I know the tense and voice?T: You can know it throughout some key words and the meanings of these sentences. Now please open your books and turn to page 13. Look at Learning about Language. First let’s do Ex 1. Complete the fol lowing sentences using suitable words or phrases from the previous sections on page 13.You can look them up in an EE dictionary. Complete the sentences with suitable words in correct forms.Several minutes later, check the answers with the whole class.T: Do you know the meaning of “pretty”?S: It means “piaoliang” in Chinese.T: Can you use another word instead of it in English?S: We can use the words “beautiful” and “lovely”.T: You are right! There are many words that have the same meaning. So when we meet them, we must pay more attention to them. Now let’s look at Ex 2. Rewrite the following sentences using words of the similar meaning to replace the underlined words.Several minutes later, check the answers with the whole class. Then do Ex 3.T: After we can use the words in sentences, we will use it in passages. Now, use the words and phrases below to fill in this passage and then answer my questions.Questions:1. What did Freddy want to do when he grew older?2. What did Freddy want to do when the dream that one could live forever now seemed impossible?T: Who can answer my questions? The first one: What did Freddy want to do when he grew older?S1: He wanted to undertake cloning so that his musical career could continue.T: Very good! What about the second one? S2: He made up his mind to enjoy his singing and accumulate many happy experiences so that when he retired he would be able to look back on his life with a great pleasure.T: Good job!Step ⅢRole-play (Ex 4)T: Now, read the questions and answers and underline the words in the answers identical with those in the questions. Then role play your dialogues. Who wants to have a try with your pair?S1: Let me have a try.A sample dialogue:S1: Excuse me, can I ask you some questions?S2: Sure!S1: What is your point of view about human cloning?S2: My opinion is that human cloning should be forbidden.S1: How can you prove a clone is authentic?S2: A real clone should be identical to its original parent, from whom the cell was taken.…T: Good job! (To all the students) You should practice more after class.Step ⅣGrammarT: Do you know the appositive clauses? Please pick out three more examples from the reading passage.Sample answers:The fact is that they are natural clones of each other.The whole scientific would follow the progress of the first successful clone, Dolly the sheep.Altogether Dolly lived for six years, half the length of the life of the original sheep.T: Now let me explain something about the appositive clauses. The appositive clause is a clause used as an appositive. The clause is an explanation to the noun before. The appositive clause belongs to noun clauses. Most of the appositive clauses may be introduced by the conjunction that. A content clause is frequently in apposition with such nouns as fact, news, idea, thought, question, reply, report, remark, hope, belief, suggestion etc.Some examples:Nobody shares my belief that he was mad.My suggestion that he was mad was not accepted.They are familiar with the opinion that all matter consists of atoms.Where did you get the idea that I could not come?We haven’t yet settled the question where we are going to spend our summer vacation.The suggestion came from the chairman that the new rule should be adopted.T: The words the fact are often inserted in front of an object clause when the clause cannot be conveniently。

Unit4 Global warming一、学生分析本堂课所教学生为高二文科班的学生，积极和活跃是他们在课堂学习实践活动中的特点。

大部分学生经过初中和高一阶段对英语这门语言的学习和掌握，已经为高二阶段的英语学习打下了较好的基础。

表现为：大部分学生能够做到课前预习和准备，课堂上能伴随课程的思路，积极主动的参与课堂活动，如小组讨论，问答练习等；并且部分学生都具有一定的自我约束能力和独立思考的能力，如对某一问题进行讨论时除了能够完成对问题的回答，还能够提出反问甚至是自己独特的见解等。

但是仍有一小部分学生由于种种原因造成了英语基础薄弱，上课不够积极主动，学习任务完成不充分等问题。

对此，在课堂活动中要进行有针对性的帮助。

如进行分组讨论时，可让他们与学习基础好的同学一组且要给予更多的鼓励，使他们尽早能提高对学习英语的兴趣。

本堂课之前学生们已经完成了对Model 6 Unit3 A healthy life 的学习任务，对健康生活的真正涵义也有了一定的理解。

因而在本堂课的引入环节中就结合这个内容进行了设问。

如“健康生活需不需要保护环境呢？”等。

且学生在这一单元以及之前所掌握的英语语言知识技能如：环境和健康的关系；如何开展讨论；如何发表自己的观点等都可以运用到本节课中。

二、本节课教材分析与教材整合1. 单元教材分析本单元以Global warming 为主题，学生通过单元教学经过思考、学习，讨论从而认识到全球变暖的真正涵义和它所带来的种种后果。

同时学生能够进一步认识我们的地球所面临的其它严重问题，激发学生的环保意识。

引导学生运用所学语言知识、句式表达自己对这些现象的看法，培养他们为自己的观点辩论的能力。

Warming Up通过真实的图片再现，使学生对能源的用途和种类有一个基本的了解。

从而为本单元主题Global warming 作了很好的铺垫。

Pre-reading部分组织学生对这些问题的讨论、回答，也让学生有进一步思考的空间，为下一步阅读做好准备。

Learning ability goals 学能目标Help the students learn how to express their opinions.Teaching important points教学重点Learn to use the structures of expressing and supporting an opinion.Teaching difficult points 教学难点How to give a speech.Teaching methods教学方法Cooperative learning.Teaching aids教具准备A computer & a projector.Teaching procedures & ways教学过程与方式Step 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 years 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 can 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 their words 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.Step Ⅵ 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, it destined 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 pe rfect. We should treat the cloning with correct attitudes. We should know the advantages and disadvantages of cloning.。

Unit 2 CloningThe First Period Warming up and Reading Teaching goals1.Enable the students to describe cloning: What is theadvantages of cloning2.Help the students analyze the writing techniques of thearticle.Teaching proceduresStep I Warming up一: 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. 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.Discussion 1. Do you want to be cloned or not Why2. Can you tell me the advantages of cloning3. And what is the disadvantage二：Look at picturesLook at the pictures and discuss which ones are natural clones and which ones are man –made. Then explain how they differ.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. 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 clone2. How is a clone produced3. What benefits can humans gain from cloning4. What problems may arise when humans are cloned5. Should we clone human6. Could cloning replace sex as the means of creating new human life7. Could a parent clone a child who is dying of a terminal illnessSuggested 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 andappearance 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 exercise1on page12 in the students’ book.2.Check the answers.3.Finish exercise2on page12 in the students’ book.4. Check the answers5.Explanation1.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..Here a way of means a manner of 一种……的方式..2. Dolly’s appearance raised a storm of objections and had a great impact on the media and public imagination. In this sentence; raise means lead. 引起/导致..全句意思是：多利的出现引起一场反对风暴;并且对媒体和公众思想产生了很大的冲击..3. However; scientists still wonder whether cloning will help or harm us and where it is leading us. “whether cloning will help or harm us”; “where it is leading us” is the objects of the word “wonder”全句意思是：科学家一直致力于研究克隆到底会有助于我们还是会伤害我们;它们将我们引向何方..Step V HomeworkAsk the students to do the following.1. Complete the exercises on page 13.2. Recite the key sentences in the text.3. What is Cloning 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 startThe second period Learning about language1 Teaching Goals:Learning the use of words and expressions in Yingzaiketang.Procedure:Step1.Revision1.Greetings2.RevisionFinish exercise1-2on page13 in the students’ book. Step 2Learn knowledge points.Ask students to learn their usage ; then ask some questions about specific use.2. Do exx123 in Yingzaiketang.3. Check the answers.Step 3 RememberRemember the knowledge points.2. Have a dictation.Step 4 Homework.Review what we learned.The third period Learning about language2 Teaching Goals:Grasp key language points.Procedures:Step I. Revision1. Have a dictation.2. Check the homework.Step 2 Study1.Get ss to study language points.2.Sum up.Step 3 Exercise1.Do some exx.2.Check the answer.3. Explain key pointsHomeworkReview the readingThe fourth period GrammarTeaching Goals:1.Revise Appositive Clause2pare attributive clause with appositive clause. Procedures:Step1 Appositive clause 1. Concept.2.Find more sentences with the appositive in the reading passage.3.Doexercise3 on page14 in ss’book.Step 2 Compare1.由于同位语从句的先行词多为fact; belief; news; idea; thought; question; reply; possibility; hope; problem; remark; report等名词;引导词常用that;所以有些同学干脆把这些名词背得滚瓜烂熟;以为只要上述名词后面出现的从句肯定是同位语从句;殊不知上述名词后面出现的从句既有可能是同位语从句;也有可能是定语从句..例如:1We were greatly pleased at the news that the Chinese women's volleyball team had won the match again.听到中国女排再次获胜的消息我们极为高兴..that引导的是同位语从句2We were greatly pleased at the news that our teacher had told us.听到老师告诉我们的消息我们感到很高兴..that引导的是定语从句从上面的例句可以看出;仅仅只先行词就断定有些名词之后一定就是同位语从句显然是片面的..那么;究竟应当如何来区分同位语从句和定语从句呢2.我们可以从以下几个方面去区分同位语从句和定语从句:1.从意义的角度来看;同位语从句与先行词之间存在的是同位或等同的关系;如例1中的news与其后的从句that the Chinese women's volleyball team had won the match again之间;"中国女排再次获胜"表示"消息"的具体内容..定语从句与先行词之间存在的是所属关系;表示"……的";起修饰限定作用..如例2中的news与其后的that our teacher had told us"老师告诉我们的"是对"消息"进行修饰限定;并不表示"消息"的具体内容..2.从语法角度来看;引导同位语从句的that是连词;只起语法作用;用来连接同位语从句;在从句中不充当任何成分;如例1中的that;而引导定语从句的that 是关系代词;它除了起引导从句的语法作用之外;还要在从句中充当句子成分;主要是作主语或宾语;如例2中的that在从句中作动词told的宾语..3.从先行词的词性来看;同位语从句的先行词大都为抽象名词;而定语从句的先行词可以是名词;也可以是代词..例如:1There is no doubt that the price of wheat will go up.毫无疑问;小麦的价格将会上涨..doubt为抽象名词;同位语从句2Those who were against the plan raised their hands.那些反对这个计划的人举起了手..Those为代词;定语从句4从可否省略来看;同位语从句的that一般不可以省略;但是定语从句中的关系代词如果在从句中充当宾语;在非正式用语中常常可以将关系代词that省略..5.从引导词来看;同位语从句有时也可以用whether来引导;但是定语从句则一般不用whether来引导..例如:The problem of whether they could finish the project is very important.他们是否能够按期完成那个项目;这个问题非常重要..6.who; which; what; when; why; how; where等词都可以用来引导同位语从句;但它们的用法和用作关系代词或关系副词时引导定语从句的用法不同:引导同位语从句的关联词是对先行词的具体内容进行进一步的解释说明;与先行词不存在指代关系;而引导定语从句的关系代词或关系副词不但在从句中充当成分;而且与其修饰的先行词指代的是同一个人或者事物..例如:1The reason why he was late for class is quite clear.他上课迟到的原因显而易见..why引导的是定语从句2He has solved the problem why the radio was out of order.他解决了收音机为何出故障的问题..why引导的是同位语从句Step 3Exercise1.Do some exx.2. Check the answers.Homework:Finish exercises on page 14 and exercises on page 56.The fifth period Extensive Reading Teaching Goals:1.Activate the Ss to show their opinions about the cloning2. Learn language points and remember them. Procedures:Step1.Revision1.Greetings2.Check the homework and ask the Ss to speak out their opinion about the medical cloningStep 2 Reading page 151.Read the passage and answer the questionsWhy shouldn’t you clone an extinct animal unless there is enough diversity in the group There will not be enough genetic variation in the group to be able to resist new illnesses.Why is it wrong to clone an extinct animal if it would have to live in a zoo It is not a good idea to clone an animal that would have to live in a zoo because it is not a suitable habitat to develop and increase its numbers. The zoo is not a natural environment for a wild animal.Why can’t you clone the DNA of animals that have been extinct longer than 10;000 years The DNA of animal more than 10;000 years old is not suitable for cloning; for it can’t survive so long.2.Reading carefully and finish discussing Exercises 13.Check the answers.Step 3 Points1.Ask students to learn language points and remember them in ying zai ketang.2.Do exercises then check the answers.Step 4 Homework.Review what we learned.The sixth period WritingTeaching GoalsEnable the Ss to write the article on this debate.Step 1 Pre-WritingImagine that you are the reporter on a local newspaper and you have been asked to write an article on this debate. To do this you must mention both sides of the argument. Remember to make a large main heading and then a small heading below it. Write around 250 words. Organize your writing in this way:Paragraph1: the topic of the debate and who won Paragraph2: the ideas of the winning sideParagraph3: the ideas of the other sideParagraph4: conclusion and your reaction to the debate; together with any idea you feel they left out.Step 2WritingGive them 15 ms to write it; then ask one student to read his passage.A sample version: Should Medical Cloning be AllowedA Debate at Xinhua Middle School Yesterday there was a very exciting debate at Xinhua Middle School about whether medical cloning should be allowed or not .After a lively discussion a vote was taken and the side arguing for medical cloning won.The arguments for medical cloning were very strongly put by the team supporting the motion. They argued that serious illnesses and people who w losing their ability to move or think could be helped by medical cloning. They explained that the procedures would be safe; quick and with no problems for the patients. They quoted that 67% of American citizens are for it to support their idea. Their arguments were very convincing.The arguments put by the team opposing medical cloning were less strong. They argued in two ways. The first reason was that the procedures were not yet secure. Their second reason was that it took many tries and many potential animals had to be killed to produce one useable embryo for research. They explained that man European countries don’t allow medical cloning research because of this. They quoted Pope John Paul Ⅱ. But their arguments were not so convincing.At the end of the debate the audience we left with a feeling of hope. They realized that diseases that seem terrible today may be able to be cured soon. Many people were excited and happy when they left they Hall .The writer of this article was among them。
