Teaching Design The Second Period Listening and speaking

Teaching goals

1.

Target language 2.

a. Words and expressions cloning, attitude, cruel, reasonable, middle-aged, bring to life,approve of

b. Sentences That’s a good/great idea

I support … because…

I agree with...because…

How can you believe that...? Do you think...?

I don’t care for your ideas because…

No,that is not reasonable because…

Your argument has convinced me because…

Your ideas sound very encouraging to me. I cannot accept your argument because…

How can you believe that? 2. Ability goals Let the students focus on the different attitude towards cloning technology. Practise the ability of listening and speaking Enable the students to express their opinions about cloning using some useful expressions. 3. Learning ability goals Teach the students how to get the specific information. Teaching important points

Listen to the materials about cloning and choose the correct answers. Learn to discuss with partners and express own ideas Teaching difficult points

Work together with partners and show their own opinions. How to grasp main ideas and details from a listening text How to express agreement and disagreement correctly Teaching methods

Listening , cooperative learning and speaking. Teaching aids

Teaching procedures & ways

Step I Revision 1. Greetings 2. Revision a. main idea of the last lesson b. some useful words and expressions

Step Ⅱ Pr-listening Ask students whether cloning is cruel or not

T: Before human clones become part of our life, perhaps we should spend some time thinking about how we should behave towards them. Now, let’s enjoy a film clip to see cloned dinosaurs and think about whether cloning is cruel to animals or human beings. After watching it ask students to exchange their opinions with their partners and lead in the listening text,

Step Ⅲ Listening The students are asked to read fast the questions and multiple answers to find out the listening points first, and then listen to the tape twice to choose the best answers. T: Please open your books on page 17. Before you listen to the tape, please read fast the questions and multiple answers to find out the listening points.You should form the habit of going through the questions and the answers to get the important listening points. Yes? And make notes if necessary. OK?

Pay more attention to these important points while listening. While listening, you’d better make notes of the listening points.

A few minutes later. T: Now, I’ll play the tape twice. Please listen carefully and pay more attention to the important points. You may make notes while listening. Notes taking are helpful for you to remember each of the important points. After listening twice, check the answers and explain some difficult listening points if necessary.

Step Ⅳ Speaking First, ask the students to read these sentences on page 18 and then ask them to discuss in group of four. T: Now turn to page 18, there’ re some useful sentences. Make the discussion with these sentences. Sample answers: Arguments for cloning :

1. Favorite pets can live forever as clones.

2. It is moral to clone pets for their owners. Arguments against cloning pets:

1. Many people don’t agree with cloning.

2. Some people think that cloning pets is selfish. 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 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 Summing up

Step Ⅴ Homework T: Boys and girls, today we have listened to some materials about cloning and made discussions about the topic. I do hope you can listen to the materials again and discuss more about it after class so that you can get very familiar with them. Besides, please finish exercises on page 55.

Now class is over. Goodbye, everyone. SS: Goodbye, sir / madam.
