14、hods 教学方法Skimming, task-based method and debate method.Teaching aids 教具准备A recorder, a projector and some slides.Teaching procedures & ways 教学过程与方式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 answering q

15、uestions.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 the clonin

16、g 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 producing a g

17、enetically 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 life, this

18、 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 twins ide

19、ntical 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 Dolly, arou

20、sed 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 cloning. Are there d

21、ifferent 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 twin of another org

22、anism. 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)

23、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 created by reproductiv

24、e 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 tomake a clone from an o

25、rdinary, 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 fiercer than expecte

26、d. 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 long time. However, sc

27、ientists 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 short play whose main

28、 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 judge let them check DNA

29、. 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

30、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 sheep is man-made. T:

31、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 information about t

32、his 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 is a clone?2. How i

33、s 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 few minutes.T: Do yo

34、u 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 the students form a go

35、od 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 copy of another animal

36、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, pay more attention t

37、o 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 same goes with the o

38、ther 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 new plant species and

39、 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 in favour of clonin

40、g 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: Why did Dollys appea

41、rance 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 decade, we will hea

42、r 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 human cloning a true

43、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. 全句汉语意思:它是一种精确复制另 一个动物或植物的方式。Here a way of means a manner of 一种的方式。T: T

44、urn 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/导 致)。全句意思是：多利的出现引起一场反对风暴，并且对媒体和公众思想产生了很大的冲 击。T: Turn to page 12. Look at the sentence: However, scientists still wo

45、nder 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：科学家一直致力于研究克隆到底 会有助于我们还是会伤害我们，它们将我们引向何方。Step V HomeworkAsk the students to do the following.1.

178、ting herefor many years” in the text.Step III Explanation一、结构形式现在完成进行时是由“助动词 have(has) + been+动词的现在分词”构成。 二、基本用法1. 表示从过去某时开始一直延续到说话时还在进行，或可能还要继续下去的动作。它通常 和“for+段时间”或“since+点时间(也可以是从句)”的时间状语连用。例如：I have been waiting for a letter from my parents. 我一直在等我父母的来信。It has been raining for three hours.雨已经下了三个

179、小时了。We have been studying here since 2019.自从 2019 年以来，我们一直在这里学习。2. 表示从过去某时开始，一直延续到说话时刻，可能刚刚结束的动作。例如：She has been sweeping the street all day. She is too tired.她一整天都在扫大街。她太累了。We have been waiting for you for two hours. We dont want to wait any longer.我们已经等你两个小时了。不想再等了。 三、常用句型1. 肯定句：“主语+have(has) been

180、+动词的现在分词+其他.”例如：I have been sitting here all the afternoon.我在这儿坐了一下午。He has been collecting all kinds of stamps since he was ten years old.自十岁起他就开始收集各式各样的邮票。2. 否定句：“主语+have(has) not been+动词的现在分词+其他.”例如：They havent been meeting each other for five years.他们有五年没见面了。He hasnt been teaching here these yea

181、rs.这些年他并没有一直在这儿教书。3. 一般疑问句：“Have(Has) + 主语 + been + 动词的现在分词？”其肯定回答：“Yes, 主语 + have(has).”否定回答：“No, 主语 + havent (hasnt).”【例如】： Have you been studying for the English test today?你今天一直在准备英语测试吗？ Yes, I have. / No, I havent.是的。 / 不，我没有。 Has Daniel been skating for two years?丹尼尔滑冰已经有两年了吗？ Yes, he has. / N

182、o, he hasnt.是的。/ 不，他没有。4. 特殊疑问句：“ 特殊疑问词 + 一般疑问句？”【例如】：What book have you been reading recently? 最近你在看什么书？ How has your uncle been getting on with his work? 你叔叔的工作进展得怎么样？四、注意事项有些不能用现在进行时的动词，如 be, have, like, love, know, see, hear 等，同样也不能用现在 完成进行时，而应用现在完成时。例如：The poor woman has been ill for a long tim

183、e. 那可怜的妇人已经病了好久了。Have you seen her parents these days?这些天你看见她的父母了吗？ 时态对比1. 现在完成进行时与现在进行时比较：现在完成进行时强调某一动作从过去一直延续到现在；而现在进行时只指目前正在发生的动 作。试比较：Susan has been reading that storybook since last night.从昨晚开始苏珊就一直在看那本故事书。 Susan is reading a storybook now. 苏珊正在看一本故事书。2. 现在完成进行时和现在完成时比较：有些动词(如：work, study, live

184、, teach 等)用现在完成进行时与现在完成时表达的意思差不多。试 比较：The teacher has been teaching at this school for ten years.十年来，那位老师一直在这所学校教书。The teacher has taught at this school for ten years.那位老师在这所学校已经教了十年书了。英语中的多数动词在这两种时态中表示不同的含义。现在完成时如果不带表示一段时间的 状语，就只能表示动作的完成，而现在完成进行时则表示动作的延续。试比较：HomeworkAsk the students finish Exercise in Word Study Part.
