Preparing lessons &self-study and exploring the problems (预习自学，探究问题)Finish the tasks given in the last period before class.Step2.Finishing plan
3、& asking questions（完成学案，提出问题）Read and answer (P16)Task1.To answer these three questions, teacher can give the students some examples as explanation, for example, Question 1. 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
4、Dolly appears, then many more. But one day all sheep get the same deadly disease. Now please think about what the results are.Maybe they would all die. Why? Because all sheep have the same arrangement of genes. Right. Now can you answer Question 1? Why shouldnt you clone an extinct animal unless the
5、re is enough diversity in the group?It is useless to clone an animal if there is not enough diversity in the group for it to overcome illnesses.Why is it wrong to clone an extinct animal if it would have to live in a zoo? If the cloned animals have to live in the zoo, it is unfair to them. They need
6、 freedom. Why cant you clone the DNA of animals that have been extinct longer than 10,000 years?Dinosaurs disappeared 65,000,000 yeas ago. So the chance of dinosaurs returning to the earth is merely a dream.Step1.Encourage the Ss to encourage others to talk in public.Let the Ss make a short discussi
7、on before class if possible.Step3.Researching cooperatively& answering questions(合作探究, 解决问题)Discussion (Question 2)Task2.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 a
8、rgue 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 doesnt absorb water. I think if we wear clothes made of its feather, we wil
9、l 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 dont think I will eat its meat. From your answers I think these animals are all useful and they all s
10、hould be restored to the earth. At the same time, we should try our best to protect them. Do you agree with me?Yes.Step 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.Step4.Summing &chewing,
11、 summarizing knowledge（总结反刍 ，知识梳理） Task3. Writing a report (P17)写作任务：Give your opinion on cloning写作要求：注意记叙文的表达方式要写明白自己的观点，层次要分明。写作建议：本单元主要讲述了“cloning”存在的 问题以及人们的态度，文中可适当就此进行发挥。(1)Discussion ( 5ms )Discuss in groups and write down the information you get. (2)Writing II ( 20ms )(3)After the discussion
12、, the students write a passage according to the writing task.( There are at least 100 words. )(4)Checking the articles. ( 12ms )1. Ask the students to check the articles for their partners.2. Show some articles on the screen, other students should give some advice.One possible version: Together with
13、 the modernest advances in science and technology, the news that Dolly had been born was announced in 1997. However, Dollys death raised many opinions about cloning. Personally, I would like to agree that cloning may do no good to our human beings.Firstly, seeing Dolly, we may think that cloning ani
14、mals can easily develop a disease. They cant live long. Secondly, we cant clone animals that have been extinct longer than 10000 years, even if the DNA of dinosaurs could survive this long. Thirdly, based on what we know now, human cloning is just a matter of time but the assumption that human clone
15、s have already been born hasnt been proved yet. In one word, personally, the chances of cloning animals and cloning human beings living on the earth naturally are merely a dream.Step 3. Deal with Questions three and four. Divide the whole class into four groups. Then they can have a competition.Step
16、5.Testing in class & improving skills（随堂检测，落实考点）TALKING (P55)Task4. 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 fam
17、ily?2. What problems did you have growing up and how can you help him / her avoid them.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
18、 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 we
19、re 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, th
20、e 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
21、cloning for reproduction purposes, but allows cloning on embryonic stem cells and remedial cloning. As we all known, everything cant be perfect. We should treat the cloning with correct attitudes. We should know the advantages and disadvantages of cloning.Step4. Ask the students to talk about the questions with the teachers help.Step6. Assessment & Homework（课堂评价，布置学案）1. Go over all the words and phrases in this unit;2. Finish the writing task unfinished in class;3. Finish the writing task .Step 5. Give the Ss the concrete homework.Reflection after teaching（教后反思）
