Step I Lead-in This topic is difficult for students. So teacher should help the students learn more about it. Do this in the way of asking and answering questions.

T：Good morning, everyone！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. besides, what other technology do you think of? Ss: Going to the space; Landing on the moon and so on T: But in recent years, a hot topic, cloning is often mentioned, especially when the cloning

Module 8 Unit 2 Cloning

Wu Chunmei Dolly the sheep appeared. Do you about cloning? Ss: No T: Since you don’t know about it, today we will learn Unit 2: Cloning. Step Ⅱ

Warming up

Activity 1 Learning what cloning is T: Perhaps most of us don’t know what cloning is. You may have first heard of cloning when Dolly the Sheep showed up on the scene in 1997.Cloning technologies have been around for much longer than Dolly, though. First things first, what is cloning and a clone? The dictionary says cloning is the technique of producing 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 life, 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 twins 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 "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 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 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 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 created 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 to make a clone from an ordinary, adult cell − in this case from a female goat’s 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 expected. Could we really clone dinosaurs.

Module 8 Unit 2 Cloning

Wu Chunmei 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. It’s not likely that dinosaur DNA could survive undamaged for such a long 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 short 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 man’s son. They quarreled and fought with each other; at last they went to the judge. The judge 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.

you want to be cloned or not? Why? 2.

If you are the judge what will you do? 3.

Can you tell me the advantages of cloning? 4.

And what is the disadvantage? Activity 2 Discussion In this part the students will discuss the relationship between the development of technology and social customs. T: As the technology develops day by day, it has a more and more important influence on the whole society. Technology affects social customs and ethics, sometimes technology may go against the conventional thinking, then comes the problem that whether we should stop the development of research or change the ethics. S1: As technology develops in almost every field, a lot of our original customs and ethics changed, either because they are out of time or not so scientific. For example millions of years ago human ate meat of animals without heating them. Later people used fire and no longer ate raw meat and they also used fire to scare dangerous animals. S2: I think we could not stop the development of technology, for it may develop in the way which is acceptable by social customs. …

Activity 3 Look at pictures

T: Look at the pictures and discuss which ones are natural clones and which ones are man –

made. Then explain how they differ. Look at the picture of Dolly the sheep. It is the most famous sheep in the world. Do you know how Dolly is different from other sheep? S: She was cloned while others were born naturally. It is the copy of another sheep. T: Good job. What can you see in the second picture? S: I can see a strawberry plant producing runners in a natural form of cloning. T: You did very well. How about the third picture? Who cut the stem off the plant? Ss: A gardener T: What does he use it to do?

Module 8 Unit 2 Cloning

Wu Chunmei S: A gardener is going to put it into a pot to produce another plant. He is actually making a copy of the plant. T: In the fourth picture, you can see there are twins. They look the same. What do you know about twins? S: There are twins of the same sex and those of different sexes. The twins here are identical in sex and appearance and are good examples of natural clones. They carry the same genetic information. The fertilized egg has split into two while inside the mother, and so produced two identical human babies. T: You are right! After looking the pictures and their production, perhaps you have some ideas about cloning.

Step

ⅢPre-reading Before class, ask the students to search for some 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 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? 5. Should we clone human? 6. Could cloning replace sex as the means of creating new human life? 7. Could a parent clone a child who is dying of a terminal illness? After a few minutes. T: Do you have other questions? Volunteer! S: I have! What is the writer’s opinion? T: Good job! I think many of you have questions, now let us read the article with the

questions. Suggest answers: 1. It is a way of making an exact copy of another animal and plant.

2. This happens in plants when gardeners take cuttings from growing plants to make new

ones, and when small parts of a plant are taken and gown in a laboratory. It also happens in animals when twins identical in sex and appearance are produced from the same original egg. 3. It can help cure disease and can help couples who have no baby to bear a new baby. 4. There may be more bad people like Hitler. 5. In my opinion, I do not agree, for it may cause many moral problems. 6. No. Because cloned human has the same quality as the real human, natural born baby’s quality is higher than his parents. 7. No. The cloned baby also has the disease. Step

Wu Chunmei Get the students to comprehend the passage quickly and accurately and meanwhile help the students form a good habit of reading. Activity 1 Fast reading.

Task 1 True or false T: Now we have got some information about cloning. There is a passage which tell us more information about clone. At first read the passage quickly, and then decide the statements are true of false 1.

Cloning means making a copy of an animal or a plant. (F) 2.

Gardeners can make a lot of money by cloning plants. (T) 3.

Cloning animals is as complicated as cloning plants.

(F) 4.

Dolly the sheep was the first successfully cone of a animal. (T) 5.

Natural clones happen in animals as well as in plants.

(T) Task 2 Summarize the main idea of each paragraph.

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 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. Activity 2 Careful reading

Task 1 Answer the questions. 1.

What are the two major uses of cloning? 2.

Why is it easier to make commercial plant clones than animal clones? 3.

What was the first clone from an adult animal? At what age did this clone die? 4.

Why is cloning controversial in some countries? Activity 2 Discussion

T: We know, everything has two sides, including cloning. 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 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 new plant species and for medical research on animals. Thirdly, it suddenly opens everyone’s eyes to the possibility of using cloning to cure serious illnesses, and even producing human beings. T: What is the writer’s opinion?

What do you think is the writer’s point of view in this reading passage? Is it in favor of cloning or against is? S1: I think the writer is in favor of it, because there are many advantages of cloning. It can help people solve many problems in our daily life.

Module 8 Unit 2 Cloning

Wu Chunmei S2: I think the writer doesn’t agree with it, because if the cloning technology can be used in an evil way, it can cause much trouble to our society. T: The next question: What is your opinion of cloning? Give the reasons.

S1: As a coin has two sides, everything has two aspects. First, if the cloning is used in a correct way it can bring many conveniences to us. Such as: curing serious illnesses and being used to produce commercial qualities of plants. On the other hand, if the cloning is used in an evil way it can cause much troubles: such as moral questions. S2: My view on cloning and nuclear transfer is that it is ethical. So actually I find no reason to clone presently. I have this opinion currently, because scientists are unable to successfully clone using nuclear transfer as of today. S3: I also have a problem with the possible effects of using nuclear transfer on a large scale. This is because I fear that cloning could greatly reduce genetic diversity. I believe if we were to interfere with the genetic diversity of an entire population we would undoubtedly fail. S4: As you can see I believe cloning using nuclear transfer should not be used on humans for any reason. I think if we were to use cloning it should be closely monitored as to what dangers are involved in having copies of people. I also think this technology should not be used until success. S5: I agree that we should develop cloning. I’m not afraid of cloning Hitlers or excited to clone Einsteins. I would say the time and the environment produced Hitler, not his DNA. So you do not need DNA from Hitler to produce a Hitler. In fact, there are Nazis already present. We should make use of cloning to benefit future generations. You can imagine that how happy the people are if they can recover from the serious illness or get back the son who has just lost his life in an accident by cloning. T: Good job! Yes, if we our human beings use the scientific technology properly it can bring many advantages to us! S: Why did Dolly’s 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 1997 announcement that a group of Scottish scientists had created a cloned sheep named Dolly. Many folks believe that within the next 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 human cloning a true possibility. We’ve cloned sheep, mice and cows, so why not humans? Some countries have set up laws banning cloning, but it is still legal in many countries. Imagine using a piece of your great-grandmother. This opens the door to many ethical problems, but it’s a door that could soon be opened. S: So what happens next? T: Whatever the reasons, the new cloning technologies have sparked many ethical debates among scientists, politicians and the general public. Several governments have considered or enacted legislation to slow down, limit or ban cloning experiments outright. It is clear that cloning will be a part of our lives in the future, but the course of this technology has

Wu Chunmei yet to be determined. Cloning could cause birth defects, but it’s not going to change society. In the absence of any legislation or regulation, cloning attempts will quietly continue. Eventually, cloning will succeed (if it hasn’t happened already), and humankind will have taken another step down the road of biological engineering. You should study hard today, and you will be able to face this difficult problem and know how to deal with it. Step Ⅴ

Tasked-based teaching methods

Discussion. Teaching time: 45 minutes Teaching procedures:

Step 1 Lead in

T: Good morning, everyone! This unit we talked about cloning. What is cloning?

Ss: It is a way of making an exact copy of another animal or plant. T: Very good! As we know, it is an advanced technology in the world. In 1996, a scientist in the world cloned the first Dolly the sheep. How is Dolly produced? S1: At first, it…. S2: Then……

T: You all did well. From the passage we know, it not only happens in plants but also in animals. As the clone appears, it brings us many advantages and also problems. What advantages does clone bring us? S3: Gardeners can use it all the time to produce commercial plants. S4: It is valuable for research on new plant species and for medical research on animals. S5: It is more important that it could help families who can’t have children of their own.

T: Wonderful. Since it is valuable for us, can we use it to save these endangered animals? Ss: Yes. T: As we know, dinosaurs are extinct 65,000,000 years ago. Can we use clone to return dinosaurs to the earth? So today we will learn “using language”. Please turn to page 15.

Step 2 Reading

Task 1 Answer the following the questions 1.

Do people clone extinct animals? Why? 2.

How many reason are mentioned why it is impossible or unsuitable to bring dinosaurs back to life through cloning? What are they? 3.

Why shouldn’t you clone an extinct animal unless there is enough diversity in the group? 4.

Why is it wrong to clone an extinct animal if it would live in a zoo?

Task 2

The opinion of cloning

Cloning is useful because: 1.

It could find a cure for illness that are presently incurable 2.

It means that endangered species can be preserved
