Now everyone, if I give you a chance to clone what will you restore then?Step Speaking task
19、T: Just now, we learned how to organize a debate, now its our turn to continue the debate. 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 ab
20、out 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 th
21、at 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 an
22、d 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 livestoc
23、k. 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.
24、 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 poss
25、ibilities 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 diseas
26、es. 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 o
27、f 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
28、 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
29、 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 ea
30、rly 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 integra
31、l 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. Religio
32、us 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 a
33、lso 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
34、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
35、 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
36、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 p
37、roperly, its really useful, but if we use it in other ways, it can bring us disaster. Sample notes: arguments for cloning 1) Cloning will be beneficial to humans. For example, if a couple cant have children, cloning could help give them a child; 2) we could use cloning to cure illnesses. arguments a
38、gainst cloning 1) 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
39、 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
40、 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 th
41、e 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 abus
42、e 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 g
43、rows 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
44、would determinedly ban cloning if I had the power. Sample speech 2: The topic of my speech is: Cloning should be encouraged As for myself, I would encourage cloning. There are several reasons. Firstly, cloning will be beneficial to humans. For example, if a couple cant have children, cloning could h
45、elp 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% o
46、f 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
47、 encourage it if I had enough power. Step 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. Writ
48、e 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 side Paragraph 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 vers
49、ion: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:
50、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
51、 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
52、way it can benefit our human beings a lot.Step HomeworkT: Now youve known how to make a debate. Why dont 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

But now as gr
75、own-ups, some adults find they cannot leave childhood behind. They become kidults (kid+adult). Being a kidult has become a lifestyle-choice among young people across Asia.Some kidults collect toys they once played with. Hello Kitty, Garfield, and Snoopy have many adult fans around the world. It is n
76、ot unusual to see a 20-something woman with a big, Garfield-shaped cushion on her sofa or a Hello Kitty mobile phone accessory. Other kidults still enjoy childrens stories and fairy tales. For example, Bloomsbury even published the Harry Potter novels with an adult cover. That way, no one else on th
77、e subway will know that an adult is actually reading a childrens book!Kidults can be like vitamins to society. Adults who value their childhood and hold on to pure, child-like emotion may be needed in such a rough and dry society, said Lee Sojung, professor of Foreign Studies at Hankuk University(韩国
78、外国语大学). He added that kidult culture may fill the generation gap between adults and kids. It could give children and their parents books, movies, and cartoon shows to enjoy together. He may be right.Tim Greenhalgh,a professor,explained that some kidults just refuse to grow up. They value childhood b
