Step Ⅱ Reading taskT: Homework check is over. 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 sometimes 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 perfecthealth 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 the debate. The topic of our deba te 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 transgeniclivestock 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 pared 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 invitro 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 disease would 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 thefact 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 e 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 brotherinlaw. 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 will be beneficial to humans. For exa mple, 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 anarticle 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 potation is: Should medical cloning be allowed? After the fierce debate, Beijing Normal University — the positive side win this potation.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 wit h 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 preconsume?Should students have extraclass during their holiday?。

人教版高中英语选修8Unit2《Cloning》word教案【美文阅读】Pandas can be saved by cloning?从1998年中国科学院动物研究所首席科学家、动物克隆与受精生物学学科带头人陈大元首次正式提出克隆大熊猫到现在，整整16年过去了，陈老仍旧执著于此。

然而爱护大熊猫，怎么说要不要通过克隆的方式呢？China has been exploring every possible means of saving giant pandas，one of the world's most endangered species，from becoming extinct，even if it means resorting to(诉诸) cloning them.Chen Dayuan，a senior scientist who specializes in cloning at the Institute of Zoology in the Chinese Academy of Sciences，introduced the idea of performing cloning techniques on giant pandas in 1998.Using initial funding of 100,000 yuan，Chen successfully produced blastocysts(胚泡) by transplanting the somatic nucleus from sample pandas into the egg cells of rabbits.The move was considered as one of the 10 biggest achievements of science and technology in 1999.It won an award of 6 million yuan and further funding of 5 million yuan for the project from the Ministry of Science and Technology.At first，two embryos were created from a surrogate mother(代母) cat who became pregnant after being in­jected with a blastocyst，but the experiment was abandoned after the cat died.Chen and his team then experimented with surrogacy on black bears.After three years of effort，a black bear became pregnant and the shape of a fetus(胎儿) could be seen on an ultrasound scan(超声波扫描检查)．However，the research was stopped in 2005 because the fetus did not completely develop before the project's deadline.“Those who are against cloning have made their voice s heard throughout the research project on cloning giant pandas.Some people believe cloning goes against nature，but it is actually a pioneering technology.If successful，it is a way tosave endangered animals，”Chen said.Some scientists take a different vie w.“While I agree that research on cloning is meaningful，it is inappropriate to use giant pandas in this type of experiment.The number of pandas is limited and human beings have yet to master knowledge about pandas' pregnancy.Cloning would do little to save the species，”said Wang Dajun，a researcher at the School of Life Sciences，Peking University.In response，Chen said that he would continue his research.【诱思导学】1．Do you think pandas can be saved by cloning？Why?______________________________________________【答案】省略2．Why are some scientists against cloning pandas?______________________________________________【答案】Because they think cloning go against nature.Period ⅠPreviewing(教师用书独具)●教学目标本课时要紧是通过学生对学案所给出的内容的学习，了解本课文中所显现的词汇，初步了解课文以及相关的背景知识，为下一堂课对课文的全面明白得起到一个铺垫作用。
