Teaching procedures & ways

Step 1 Lead-in (Speaking) Ask the students to speak out their opinion about the medical cloning and check what they have learned and how much they have grasped.

Step 2 Reading task(Pair work) Let students discuss the following questions with their partners. Q 1: What is the definition of debate? A1: A debate is an activity in which students can discuss two sides of an issue. There is a chairperson to charge it. Q 2: Tell me the process of a debate in your own words. A2: The leading debater who supports the topic speaks first, then another one who disagrees with the topic speaks, then other people take turns to give a free discussion. Towards the end of the debate, the last speaker of each side will summarize the arguments that have been made to support their point of view. Step 3 Discussion (Group work) Read the passages on page 58 and students can be divided into two teams. One side agrees with the medical cloning and the other side is against the medical cloning. Then show the questions. Give students 6 minutes to prepare their answers. Team A:

1. What’s their argument?

2. Two reasons for medical cloning.

3. Do you agree with them? Why? Team B:

1. What’s their argument?

2. Two reasons against medical cloning.

3. Do you agree with them? Why? Sample answers:

Team A:

Q1: They support the idea that there should be medical cloning.

Q2: a. There is no danger of the body refusing to accept the new calls.

b. Patients can be treated immediately.

Q3. Yes, I agree with them. Because the medical cloning can help our human beings to cure many diseases. With the help of the cloning techniques, people can be restored to perfect health and be able to live a good life. No, I disagree with them. I think all animals including human beings are natural things on the earth. We should not damage this natural rule. Team B:

Q1. They disagree that there should be medical cloning.

2

Q2. a. It brings many ethical problems.

b. Many scientists are also worried about the efficiency of the system.

Q3. Yes, I agree with them. Because the medical cloning brings many serious problems to our human beings. We must be very cautious about cloning until these problems are solved. No, I disagree with them. Because all of us want to lead a meaningful life. We should try our best to realize our dream.

Step 4 Speaking task The topic of our debate is “should we clone?” Now choose the team you agree with.

Divide the whole class into four groups, two agree and two disagree. Show the following tips before debating: Center on the subject of the debate. Organize main ideas that support your point of view. List your own ideas. Make a conclusion.

Then give students 10 minutes to prepare, everyone finds their roles in the debate. As a chairperson, the teacher is in charge of the debate. Ask the students to do as follows: First leading speaker gives an argument. Then others give speech freely. Last the fourth speaker gives a summary. Chairperson: From our debate, we really can learn much. All of you have performed well. Whether can we clone? This is a long term argument. To me, if people can use this method properly, it’s really useful, but if we use it in other ways, it can bring us disaster.

Sample notes:

arguments for cloning

1) Cloning will be beneficial to humans. For example, if a couple can’t have children, cloning could help give them a child;

2) we could use cloning to cure illnesses.

arguments against cloning

1) health risks from mutation of genes;

2) emotional risks;

3) risk of abuse of the technology;

4) against nature;

5) cloned animals get ill and die quite young;

6) people are afraid of that scientists will create thousands of copies of the same person;

7) Cloning is dangerous because scientists my create monsters by mistake. Sample speech 1:

The topic of my speech is: Cloning should be banned. If I had the power, I would ban cloning for several reasons.

Firstly, it is against nature and dangerous. Any living things have life and death recycle periods, which promote the evolution of life. The cloning technique is extremely risky right now. An abnormal baby would be a nightmare come true. And people are worried about the possibility that the genetic material used from the adult will continue to age so that the genes in a newborn baby clone could be 30 years old or more on the day of birth. Also monsters may be created by mistake. According to a survey, 29 European countries do not permit medical cloning. Secondly, people are afraid of that scientists will create thousands of copies of the same person. There are powerful leaders in every generation who will seek to abuse this technology for their own purposes. Going ahead with cloning technology makes this far more likely. What would happen if Hitler was cloned? That would mean more severe disasters and destruction upon human civilization. Thirdly, cloning will result in high emotional risks. Just think: a child grows up knowing her mother is her sister, her grandmother is her mother. Her father is her brother-in-law. Every time her mother looks at her she is seeing herself growing up. The family environment and relationship will be totally different. What kind of pressures will the child feel?

All in all, I would determinedly ban cloning if I had the power.

Sample speech 2:

The topic of my speech is: Cloning should be encouraged

As for myself, I would encourage cloning. There are several reasons.

Firstly, cloning will be beneficial to humans. For example, if a couple can’t have children, cloning could help give them a child. Secondly, we could use cloning to cure illnesses. For example, if there is something wrong with some part of a human body, we could clone a healthy one to replace it. For another, if a child is seriously ill or disabled, we could clone another one. According to a survey, 67% of over 1,000 people want medical cloning to continue in America. And in Britain and China medical cloning has been allowed. Thirdly, clone technology could be used in other ways. For example, we can save the endangered animals by cloning.

In a word, cloning technology has a promising future. I would encourage it if I had enough power.

Step 5 Homework ( Writing) Imagine that you are the reporter on a local newspaper and you have been asked to write an article on this debate.

A sample version: Should Medical Cloning be Allowed

A debate between Beijing Normal University and Nanjing University In December 26th 2005, there is a debate between Beijing Normal University and Nanjing University. The two teams began their argument about the cloning techniques. The topic of this compotation is: Should medical cloning be allowed? After the fierce debate, Beijing Normal University — the positive side win this compotation.

The view of the positive side is: there should be medical cloning. The view of the negative side is: there should not be medical cloning.

This debate is very successful. As the coin has two sides, every technology can bring the advantages to our society, and also can bring the negative effects to our human beings. So when we judge a new technology good or not good, we should look at whether there are more advantages than its disadvantages or not. If we use it in a proper way it can benefit our human beings a lot.
