Do you think it would be a good idea to clone humans? What effects do you think human cloning might have? 2. Ability goals能力目標(biāo) Enable the students to know something about cloning, and give their own opinions about cloning. 3. Learning ability goals學(xué)能目標(biāo) Help the students learn how to describe the advantages and disadvantages of human cloning with the target language. Teaching important points教學(xué)重點 Talk about cloning and human cloning. Teaching difficult points 教學(xué)難點 How to describe the advantages and disadvantages of human cloning. Teaching methods教學(xué)方法 Discussion and speaking. Teaching aids 教具準(zhǔn)備 A projector. Teaching procedures and ways教學(xué)過程與方式 Step I Lead-in Walk into the classroom with a sad face. T: Good morning, class. Ss: Good morning, Miss Wang. T: How are you today? S: Fine. But you look so upset, what happened? T: My pet cat died of some unknown disease this morning, which makes me so sad. You know I love her so much that I nearly can’t live without her. However, nothing can take her place in my mind, what can I do? S: Why don’t you have one that is exactly the same as yours by cloning? I think it’s the only way to solve your problem. T：What’s clone? S1: A clone is a copy. S2: Cloning is one of the most popular technologies in the 20th century. T：What other technologies do we have in recent years? S1: Maybe the most influential technology is puter science, which has contributed a lot to our society in many fields. Now, for most of us, we can’t live without puters. S2: Every coin has two sides, while we benefit a lot from puter technology, it does do harm to us in some degree. For example, many people get puter disease, and some students give up schooling because of being addicted to puter games. S3: Air-conditioner is widely used today. We can spend both winter and summer without worrying about being too cold or too hot because we can control the temperature ourselves. But as a result, our environment is polluted at the same time; our planet is being warmer and warmer, which partly results from our using of air-conditioners. T: You are right. Just now you mentioned cloning. Now let’s see some pictures. Show the pictures on the textbook on the screen. Step II Wele to the unit T: Here are six pictures. They are all clones. Maybe all of you are familiar with Dolly, aren’t you? Ss: Yeah. T: Where and when was Dolly born? Is she still alive? Who can give us some information about Dolly? S: Dolly the sheep was born on February 24, 1997 in Edinburgh Scotland. She was cloned from a cell of another sheep. Dolly died in February, xx, after developing a progressive lung disease. T: Do you know other cloned animals? S: A cloned frog first appeared in the world in 1952. In 1962, a tadpole was successfully cloned. What’s more, it was announced that human embryo was successfully cloned in a pany in America on November 25th, xx. T: Now suppose you’ve grasped cloning technology, what would you like to clone? Why? S1: I’d like to clone dinosaurs, which disappeared several billion years ago. Because I want to reappear the prosperity in dinosaurs’ times and let our future generation have the opportunity to see the giant animals. S2: I don’t like to clone animals in ancient times because I think it means nothing. I want to clone water. As we all know, water is very important to our planet and even the whole universe. However, with the development of our society, the amount of water cannot satisfy our needs. Besides, in some areas in the world, people even haven’t enough water to drink. S3: I agree with S2 that water is of great importance to us. But in my opinion, food is more important. If we can successfully clone food, we can save people in South Africa who are suffering from hunger; it will be of great benefit to the world. S4: It’s a fact that our living environment is being worse and worse, so it’s our responsibility to protect the environment around us. Therefore, I would like to clone the tropic rainforest in Amazon. I will place it in Sahara to purify the environment and I’m sure that would be wonderful. S5: The human organ would be my choice. Every year, a large number of people in the world die from lack of human organs to replace their sick ones. And my grandfather is an example. S6: I would prefer to clone a luxurious villa, a most perfect car and a lot of money to enjoy myself! To live a luxurious life as a millionaire has been my dream for a long time. T: All of you have good wishes! Science is developing so fast that it is even beyond our imagination. Cloning is one of the more advanced technologies! Everything on earth is unique, but cloning makes it possible to have a double. Do you know why we’re different from each other? Ss: ... T: It’s because of genes. Genes are the instructions for life. They make each individual plant or animal different and unique. Do you think it would be a good idea to clone humans someday? S: I don’t think it would be a good idea to clone humans because the earth we are living on is already overpopulated, and cloning humans would make the situation worse. S: I don’t quite agree. I think it would be fun to clone humans. If you have a cloned sister or brother, you won’t feel lonely anymore. What’s more, for those couples who can’t have a baby, cloning would help them have their own babies. Step III Discussion Deal with the questions in activity F. T: Now work in pairs and discuss the questions in activity F. Several minutes later, ask some pairs to demonstrate their conversations. A sample conversation: A: If we use cloning technology, there won’t be any idiot in the world and, as a result the human society will be improved. B: I don’t agree. If persons like Hitler (希特勒) were cloned they would bring troubles to our society. A: Using cloned organs, we can save the lives that are dying of incurable diseases, such as cancer and AIDS. B: But there will be population problem. You know our earth is overpopulated now. If we clone humans, there will be more and more people and the earth will run out of resources. I think human being is against nature law. If we stick to the opinion that human cloning is right, we’ll be punished by nature in the future. A: Police would have difficulty in arresting the criminals because of clones. So I think governments should pass laws to make human cloning illegal. B: I agree. Our moral principles will be destroyed. What if someone has two fathers? Or two wives? A: Even if the parents who have lost their children would feel happy when they see their loved ones, the clone’s behavior and thoughts can’t be like their daughters, sons. Maybe they will regret. B: I just want to see one “I” in the world, I can’t imagine what I would feel if there are two “I”! How horrible! T: Almost all of you are for the view that human being shouldn’t be cloned. I can’t agree more. We have our principles while nature has its own ones. We can’t attempt to change something in the nature, or we’ll be punished! So we should try our best to build a society in harmony with nature instead of against nature. Step IV Homework Preview the text on P42. Search the Internet for more information about cloning. The Second Period Reading Teaching goals教學(xué)目標(biāo) 1. Target language目標(biāo)語言 a. 重點詞匯和短語 announcement, embryo, tissue, organ, interfere, real-life, cell, normal, praise, breakthrough, intention, anxiety, adopt, desperate, genetically, deliver, medical, succeed, benefit, totally, immoral, consequence, ment, advance, negative, correct, strict, on the one hand, print out, in general, push ahead with, end up, for sale, use up, put in place, e across b. 重點句子 A recent announcement by scientists that they have successfully cloned the first human emerge has caused much debate and has shocked many people around the world. In general the scientists were praised for their wonderful scientific breakthrough while cloning human embryos is illegal in many countries some scientist are already pushing ahead with research so as to deliver a cloned human body. We could produce a monster or even a superhuman race that could one day end up replacing us. 2. Ability goals能力目標(biāo) Enable the students to learn different opinions on cloning. 3. Learning ability goals學(xué)能目標(biāo) Help the students to learn how to understand scientific terms and analyze the passage according to the reading strategy. Teaching important points教學(xué)重點 How to understand the writer’s point of view. Teaching difficult points教學(xué)難點 How to understand the scientific terms. Teaching methods教學(xué)方法 Listening, skimming, scanning and discussion. Teaching aids教具準(zhǔn)備 A tape recorder, a projector and a puter. Teaching procedures and ways教學(xué)過程與方式 Step I Revision Check the homework: Ask some students to share their information about cloning found on the Internet. Step II Lead-in T: Good. I think you really did a lot of work after class. Thank you very much. Today I would like to introduce a famous guy to you first. Look at the screen please. Show a picture of Frankenstein monster on the screen. T: Have you ever seen this monster? S: Yes, it’s called Frankenstein monster. T: How much do you know about it? S: Frankenstein is the character of a science fiction written by Shelley’s wife, Mary Shelley, who was named the ancestor of science fiction. S: In this fiction, professor Frankenstein created a monster, but the monster at last killed the professor and his family because of its anger as he gave life to it while the society couldn’t accept it. It’s really a scientific tragedy. T: Excellent. And now if we call somebody Frankenstein monster, we mean that he is hurt by something he has created. Frankenstein created a life and then was punished to death. Do you think there is something similar between Frankenstein and the scientists today who are concentrating on human cloning? Will they be punished some day? ... Now we’re going to read a passage, “The perfect copy”. Step III Pre-reading In this procedure, students will do fast reading and answer the questions in activity A. T: Now you please read the article and letters fast and answer the questions in activity A. I’ll give you only 2 minutes. After 2 minutes, ask students to report their answers. Suggested answer: 1. The article gives both the anti- and pro-cloning point of view. 2. Its name was Dolly. 3. Obviously she is anti-cloning. T: Sometimes it can be very difficult to judge the writer’s point of view. So how can you tell that the writer gives both an anti- and pro-cloning point of view? Is there any clues? S: For example, in the first paragraph, the use of “on the one hand” and “on the other hand”, they introduce two opposite opinions. More clues: Para 2: ... However, in general the scientists were praised for ... Para 3: ... However, some people consider that ... Para 4: Even though ..., it is good news ... Step IV Skimming In this procedure, encourage the students to develop their predictive skill by reading the beginning and the ending to guess as much as they can about the passage and understand the meaning of the text as a whole. T: Articles about science is a little difficult to understand, don’t you think so? Ss: Yes. T: It’s just because there are some scientific terms in it. You can understand the article very well only if you understand those terms. To understand an article about science, you should get a general idea first according to the first and last paragraph. Now please read these two paragraphs and answer my questions on the screen. Show the following questions on the screen. 1. What’s the first paragraph about? 2. What’s the last paragraph about? 3. What is the passage about? T: Look at the first question. What’s the first paragraph about? S1: In the first paragraph, we know that scientists’ success in cloning caused much debate. S2: Two different opinions are mentioned briefly in this paragraph. T: Good. Then what about the last paragraph? S3: China’s achievements on cloning are mentioned. T: Can you guess what the whole passage is about now? S4: I think it will tell different opinions about cloning. S5: The passage will tell us the achievements on cloning in different countries all over the world. T: You all did very well. Let’s scan the passage to check your predictions, OK? Step V Scanning While scanning, the teacher should play the tape for the students. The students check their predictions and build an outline of the text in their minds. T: Now read the text carefully. I’ll play the tape for you, your task is to find out the main idea of each paragraph and see whether your predictions are correct or not. Three minutes for you. After 3 minutes, check the answers. Ask several students to tell the main idea of each paragraph. Then show the following. Paragraph Main idea Para 1 An announcement about human embryo cloning which has caused much debate Para 2 Explain cloning as a wonderful scientific breakthrough and give the example of Dolly Para 3 Dolly’s creator’s opinion about human cloning Para 4 A saleswoman supports cloning very much for her personal purpose. Para 5 Some scientists are pushing ahead with the research to clone human. Para 6 The achievements of China on cloning. T: Pauline Carter and Colin Jake wrote letters to the newspaper editor to express their opinions on cloning. We know Pauline is anti-cloning. How about Colin? Read the letter by Colin quickly and judge his point of view. S: He is pro-cloning. He thinks cloning is fantastic and he is in plete agreement with human cloning. T: Good job! Now let’s scan the article and the two letters and finish activity C1. I’ll give you three minutes. 3 minutes later, check the answer. T: Now look at activity C2, find the reasons why people are pro- or anti-cloning in the article and letters. Suggested answers: Pro-cloning Anti-cloning 1. Produce valuable tissues and organs that could be used to save human lives. 1. May produce a real-life Frankenstein’s monster. 2. Create new tissues and organs that could be used to cure diseases like cancer. 2. Could create more diseases in the animal world. 3. It’s a wonderful scientific breakthrough 3. It’s immoral and shows no respect for human life. 4. Those who cannot have baby can have a cloned baby. 4. Could one day end up replacing human beings. 5. The human race is
