14、 methods 教學方法Skimming, task-based method and debate method.Teaching aids 教具準備A recorder, a projector and some slides.Teaching procedures & ways 教學過程與方式Step I Lead-inThis topic is difficult for students. So teacher should help the students learn more about it. Do this in the way of asking and ans

15、wering questions.T: 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 th

16、e cloning Dolly the sheep appeared. You may have first heard of cloning when Dolly the Sheep showed up on the scene in 2019. Cloning technologies have been around for much longer thanDolly, though. First things first, what is cloning and a clone? The dictionary says cloning is the technique of produ

17、cing 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. It sounds very different and complicated to us. In fact, I mean, in our daily li

18、fe, 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 t

19、wins identical in sex and appearance are produced from the same original egg. The fact is that cloning plants is straightforward but the cloning of animals is more complicated. The possibility of human cloning, raised when Scottish scientists at Roslin Institute created the much-celebrated sheep &qu

20、ot;Dolly", aroused worldwide interest and concern because of its scientific and ethical implications. You can give your questions if you are interested in this topic. I am here today one of the scientists who work in this field. I am ready to answer any of your questions.S: Now we know what is

21、cloning. Are there different types of cloning?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

22、 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

23、or DNA cloning, (2) reproductive cloning, and (3) therapeutic cloning.S: Was Dolly created by what cloning? And why was Dolly so important?T: Reproductive cloning is a technology used to generate an animal that has the same nuclear DNA as another currently or previously existing animal. Dolly was cr

24、eated by reproductive cloning technology. She was the first mammal to be cloned from adult DNA taken from an adult cell. Previously, animals had only been cloned using embryo cells which already have the potential to become a complete embryo in its own right. The big breakthrough with Dolly was toma

25、ke a clone from an ordinary, adult cell in this case from a female goats udder.S: Have you seen Jurassic Park? In this feature film, scientists use DNA preserved for tens of millions of years to clone dinosaurs. They find trouble, however, when they realize that the cloned creatures are smarter and

26、fiercer than expected. Could we really clone dinosaurs.T: In theory? Yes. What would you need to do this? A well-preserved source of DNA from the extinct dinosaur, and a could serve as a surrogate mother. In reality?Probably not. Its not likely that dinosaur DNA could survive undamaged for such a lo

27、ng time. However, scientists have tried to clone species that became extinct more recently, using DNA from well-preserved tissue samples.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 s

28、hort 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 mans son. They quarreled and fought with each other; at last they went to the judge. The judg

29、e 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

30、the judge what will you do?3. Can you tell me the advantages of cloning?4. And what is the disadvantage?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.S: I think the twins are natural clones and the Dolly sh

31、eep is man-made. T: You are right! Can you explain how they differ?S: The twins were born at the same time, but the Dolly sheep is man-made. T: Anything else? Who want have a try?S: I think the identical dog is man-made. T: Good JobStep II Pre-readingBefore class, ask the students to search for some

32、 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.Ss: Yes, sir / madam. Questions about cloning:1. What

33、 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? Should we clone human?5 Could cloning replace sex as the means of creating new human life?6Could a parent clone a child who is dying of a terminal illness? After a

34、few minutes.T: Do you have other questions? Volunteer! S: I have! What is the writers opinion?T: Good job! I think many of you have questions, now let us read the article with the questions.Step III While- readingGet the students to comprehend the passage quickly and accurately and meanwhile help th

35、e students form a good habit of reading.T: Have 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 cop

36、y 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 Post-readingAsk the students to read the passage again to finish three tasks.T: Now lets listen to them. While listening,

37、pay more attention to the correct pronunciation and tone. Then read the text by yourselves to get the answers to the three tasks. You can work in groups.T: First, What are the problems or dangers of cloning?S: Let me have a try! First, the cloned animals have the same illness of old animals and the

38、same goes with the other species. Second, the cloned animals have short life and can cause moral questions.T: You are right! And what are the advantages of cloning?S: I know! Firstly, gardeners use it all the time to produce commercial quantities of plants. Secondly, it is valuable for research on n

39、ew plant species and for medical research on animals. Thirdly, it suddenly opens everyones eyes to the possibility of using cloning to cure serious illnesses, and even producing human beings.T: What is the writers opinion? What do you think is the writers point of view in this reading passage? Is it

40、 in favour of cloning or against is?S1: I think the writer is in favour of it, because there are many advantages of cloning. It can help people solve many problems in our daily life.T: Good job! Yes, if we our human beings use the scientific technology properly it can bring many advantages to us!S:

41、Why did Dollys appearance raise a storm of objections and have a great impact on the media and public imagination?T: Because nothing really prepared the world for the 2019 announcement that a group of Scottish scientists had created a cloned sheep named Dolly. Many folks believe that within the next

42、 decade, we will hear a more shocking announcement of the first cloned human. Scientists in South Korea have already created human embryonic stem cells through cloning. Until now, the idea of human cloning has only been possible through movie magic, but the natural progression of science is making h

43、uman cloning a true possibility. Weve cloned sheep, mice and cows, so why not humans? ExplanationT: Now lets deal with some language points. Turn to page 11. Lets look at the sentence: It is a way of making an exact copy of another animal and plant. 全句漢語意思:它是一種精確復制另 一個動物或植物的方式。Here a way of means a

44、manner of 一種的方式。T: Turn to page 12. Look at the 8th line. Dollys 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/導 致)。全句意思是：多利的出現(xiàn)引起一場反對風暴，并且對媒體和公眾思想產生了很大的沖 擊。T: Turn to page 12. Look at the sentence: However,

45、 scientists still wonder whether cloning willhelp 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：科學家一直致力于研究克隆到底 會有助于我們還是會傷害我們，它們將我們引向何方。Step V HomeworkAsk the students to do the following.1.
