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. Homework1.Recite new words and expresstions2.Rread the textTeaching reflection:。
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。

Please turn to page 58. Today we will make a debate. To begin with, I want to ask you what your opinion about debate is, have you seen any TV debates?S: Yeah, we have seen college students’ debate on TV.S2: I know in a debate there is one chairperson some-times two, four members each group, two leading debaters.T: You are right. Do you want to know more details about a debate?S: Yeah.Ask the students to read the debate rules.T: OK. Stop reading. Here are some questions for you. Question 1: What is the definition of debate?Ss: A debate is an activity in which students can discuss two sides of an issue. There is a chairperson to charge it.T: Question 2: Tell me the process of a debate in your own words.S: The leading debater who supports the topic speaks first, then another one who disagrees with the topic speaks, then other people take turns to give a free discussion. Towards the end of the debate, the last speaker of each side will summarize the arguments that have been made to support their point of view. T: Excellent, thanks for your answer. In our textbook there is an example of debate, read the topic carefully and discuss the questions with your partner. And I will divide you into two teams. One side agrees with the medical cloning and the other side is against the medical cloning.Then show the questions. Give students 6 minutes to prepare their answers. Team A: 1. What’s their argument?2. Two reasons for medical cloning.3. Do you agree with them? Why?Team B: 1. What’s their argument?2. Two reasons against medical cloning.3. Do you agree with them? Why?Sample answers:Team A: Q1: They support the idea that there should be medical cloning.Q2: a. There is no danger of the body refusing to accept the new calls.b. Patients can be treated immediately.Q3. Yes, I agree with them. Because the medical cloning can help our human beings to cure many diseases. With the help of the cloning techniques, people can be restored to perfect health and be able to live a good life.No, I disagree with them. I think all animals including human beings are natural things on the earth. We should not damage this natural rule.Team B: Q1. They disagree that there should be medical cloning.Q2. a. It brings many ethical problems.b. Many scientists are also worried about the efficiency of the system.Q3. Yes, I agree with them. Because the medical cloning brings many serious problems to our human beings. We must be very cautious about cloning until these problems are solved.No, I disagree with them. Because all of us want to lead a meaningful life. We should try our best to realize our dream.Step Ⅲ Speaking taskT: Just now, we learned how to organize a debate, now it’s our turn to continue thedeba te. The topic of our debate is “should we clone?” Now choose the team you agree with.Divide the whole class into four groups, two agree and two disagree.T: To begin this debate, I will give you some information about clone. You can choose what you need. During the speech, you can make notes so that you do not forget what you want to say. In our debate the person who speaks last must summarize your ideas. Here are some tips for you.Show the following.Center on the subject of the debate.Organize main ideas that support your point of view.List your own ideas.Make a conclusion.Ask the students to read the following informationShow the following.Why should we use cloning?The goals and purposes for cloning range from making copies of those that have deceased to better engineering the offspring in humans and animals. Cloning could also directly offer a means of curing diseases or a technique that could extend means to acquiring new data for the sciences of embryology and how organisms develop as a whole over time. Currently, the agricultural industry demands nuclear transfer to produce better livestock. Cloning could massively improve the agricultural industry as the technique of nuclear transfer improves. The goal of transgenic livestock is to produce livestock with ideal characteristics for the agricultural industry and to be able to manufacture biological products such as proteins for humans. Researchers can harvest and grow adult cells in large amounts compared to embryos. Scientists can then genetically alter these cells and find which ones did transform and then clone only those cells. Scientists also ponder the idea of cloning endangered species to increase their population. The possibilities are endless. However, we are actually doing much of this research for the improvement of life for humans. Scientists foresee the cloning of pigs that will produce organs that will not be rejected by humans. Cloning also provides better research capabilities for finding cures to many diseases. There are also possibilities that nuclear transfer could provide benefits to those who would like children. For instance, couples who are infertile, or have genetic disorders, could use cloning to produce a child. Equally important, women who are single could have a child using cloning instead of in-vitro fertilization or artificial insemination. Cloning could also provide a copy of a child for a couple whose child had died.Why should we not use cloning?The biggest problem with the use of cloning on a large scale is the decline in genetic diversity. Think about it, if everyone has the same genetic material, what happens if we lose the ability to clone. We would have to resort to natural reproduction, causing us to inbreed, which will cause many problems. Also, if a population of organisms has the same genetic information, then the diseasewould wipe out the entire population. Helping endangered species by cloning will not help the problem. Currently, zoologists and environmentalists trying to save endangered species are not so much having trouble keeping population numbers up, but not having any animals to breed that are not cousins. The technique of nuclear transfer is also early in its developmental stages. Thus, errors are occurring when scientists carry out the procedure. For instance, it took 277 tries to produce Dolly, and Roslin scientists produced many lambs with abnormalities. If we tried to clone endangered species we could possibly kill the last females integral to the survival of a species. This may be the main reason science is holding out on cloning humans.Other arguments for cloning include if we are taking nature into our own hands by cloning animals or people. People question when we will draw the line for getting involved in natural events. Religious organizations consider nuclear transfer to cause men to be reproductively obsolete. This claim was deduced by gathering of the information that cloning requires only oocytes, any cell, and a woman to develop in. They also claim that cloning does not respect the fact that humans have souls. They also consider cloning unnatural, and say we are taking the work of God into our own hands. There is also a debate as to the moral rights of clones. Some say their rights will be defied because clones are not granted the birth of newness. We would not receive clones with such excitement as a child of a couple who conceived naturally. If natural reproduction were to occur, genetic variation would occur. They say cloning would deprive a person of uniqueness. They argue that identical twins are not unique from each other, but that they are new in genetic variation and unique from anything that came before them. People also wonder what mental and emotional problems would result if a clone was to find out that he or she was cloned.Then give students 10 minutes to prepare, everyone finds their roles in the debate. As a chairperson, the teacher is in charge of the debate. Ask the students to do as follows:First leading speaker gives an argument.Then others give speech freely.Last the fourth speaker gives a summary.Chairperson: From our debate, we really can learn much. All of you have performed well. Whether can we clone? This is a long term argument. To me, if people can use this method properly, it’s really useful, but if we use it in other ways, it can bring us disaster.Sample notes:arguments for cloning1) Cloning will be beneficial to humans. For example, if a couple can’t have children, cloning could help give them a child;2) we could use cloning to cure illnesses.arguments against cloning1) health risks from mutation of genes;2) emotional risks;3) risk of abuse of the technology;4) against nature;5) cloned animals get ill and die quite young;6) people are afraid of that scientists will create thousands of copies of the same person;7) Cloning is dangerous because scientists my create monsters by mistake. Sample speech 1:The topic of my speech is: Cloning should be banned. If I had the power, I would ban cloning for several reasons.Firstly, it is against nature and dangerous. Any living things have life and death recycle periods, which promote the evolution of life. The cloning technique is extremely risky right now. An abnormal baby would be a nightmare come true. And people are worried about the possibility that the genetic material used from the adult will continue to age so that the genes in a newborn baby clone could be 30 years old or more on the day of birth. Also monsters may be created by mistake. According to a survey, 29 European countries do not permit medical cloning. Secondly, people are afraid of that scientists will create thousands of copies of the same person. There are powerful leaders in every generation who will seek to abuse this technology for their own purposes. Going ahead with cloning technology makes this far more likely. What would happen if Hitler was cloned? That would mean more severe disasters and destruction upon human civilization. Thirdly, cloning will result in high emotional risks. Just think: a child grows up knowing her mother is her sister, her grandmother is her mother. Her father is her brother-in-law. Every time her mother looks at her she is seeing herself growing up. The family environment and relationship will be totally different. What kind of pressures will the child feel?All in all, I would determinedly ban cloning if I had the power.Sample speech 2:The topic of my speech is: Cloning should be encouragedAs for myself, I would encourage cloning. There are several reasons.Firstly, cloning wil l be beneficial to humans. For example, if a couple can’t have children, cloning could help give them a child. Secondly, we could use cloning to cure illnesses. For example, if there is something wrong with some part of a human body, we could clone a healthy one to replace it. For another, if a child is seriously ill or disabled, we could clone another one. According to a survey, 67% of over 1,000 people want medical cloning to continue in America. And in Britain and China medical cloning has been allowed. Thirdly, clone technology could be used in other ways. For example, we can save the endangered animals by cloning.In a word, cloning technology has a promising future. I would encourage it if I had enough power.Step Ⅳ WritingT: Imagine 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: Paragraph 1: the topic of the debate and who wonParagraph 2: the ideas of the winning sideParagraph 3: the ideas of the other sideParagraph 4: conclusion and your reaction to the debate, together with any idea you feel they left outA sample version:Should Medical Cloning be AllowedA debate between Beijing Normal University and Nanjing UniversityIn December 26th 2005, there is a debate between Beijing Normal University and Nanjing University. The two teams began their argument about the cloning techniques. The topic of this compotation is: Should medical cloning be allowed? After the fierce debate, Beijing Normal University — the positive side win this compotation.The view of the positive side is: there should be medical cloning. The view of the negative side is: there should not be medical cloning.This debate is very successful. As the coin has two sides, every technology can bring the advantages to our society, and also can bring the negative effects to our human beings. So when we judge a new technology good or not good, we should look at whether there are more advantages than its disadvantages or not. If we use it in a proper way it can benefit our human beings a lot.Step Ⅴ HomeworkT: Now you’ve known how to make a debate. Why don’t you arrange one with your classmates? Choose whichever topic interests you but make sure that it is popular topic. Organize it as you have been shown in this unit. Enjoy the argument and let the better side win!Teacher can give the students some issues to infer:Should students use phones in schools?Should students wear school clothes?Should senior 3 students have PE class?Protect ourselves first or save others first?Save money or pre-consume?Should students have extra-class during their holiday?。
