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?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 Ⅲ While-readingGet the students to comprehend the passage quickly and accurately and meanwhile help the students form a good habit of reading.divide 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.Step Ⅳ Post-readingAsk the students to read the passage again to finish three tasks.T: Now let’s listen to the tape. While listening, pay more attention to 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 the 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. Third ly, 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 favour of cloning or against it?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.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.Step Ⅴ HomeworkAsk the students to do the following.1.

Some days later a Dolly appears, then many more. But one day all sheep get the same deadly disease. Now please think about what the results are.S: Maybe they would all die.T: Why?S: Because all sheep have the same arrangement of genes.T: Right. Now can you answer Question 1? Why shouldn’t you clone an extinct animal unless there is enough diversity in the group?S: It is useless to clone an animal if there is not enough diversity in the group for it to overcome illnesses.T: Why is it wrong to clone an extinct animal if it would have to live in a zoo?S: If the cloned animals have to live in the zoo, it is unfair to them. They need freedom.T. Why can’t you clone the DNA of animals that have be en extinct longer than 10,000 years?S: Dinosaurs disappeared 65,000,000 yeas ago. So the chance of dinosaurs returning to the earth is merely a dream.Step Ⅲ Discussion (Question 2)This is a speaking task. Ask the students to have a discussion in groups, organize their words properly, and give vivid description of the chosen animals.T: Now look at the table on page 16, discuss in pairs which extinct animals described are worth restoring by means of cloning. Choose one animal and use the information to help you argue why this animal should be restored to the earth.Give the students six minutes to discuss.Step Ⅳ Writing a report (P17)Deal with Questions three and four. Divide the whole class into four groups. Then they can have a competition.T: Now everyone, imagine all of you are owners of your chosen animal. Now work together, and give us a vivid description of your pet, then I will decide which one is the best to be resorted to the earth.Several minutes later, the students give performances. At the same time, list some major points on the blackboard.T: Well done everyone. It is really hard for me to choose, let us vote OK?Step Ⅴ TALKING (P55)Ask the students to talk about the questions with the teacher’s help.T: Look at the questions on page 54. Do you know how to show your opinion? You can discuss the following questions with your partner and use these expressions on page 54.1. How would you feel about having a clone of yourself in the family?2. What problems did you have growing up and how can you help him / her avoid them.Step Ⅵ HomeworkT: Write down your feelings and attitudes towards clone. Combine them into a composition.The Fourth Period GrammarStep Ⅰ RevisionCheck the students’ homework.Step ⅡGrammarT: Do you know the appositive clauses? Please pick out three more examples from the reading passage.Sample answers:The fact is that they are natural clones of each other.The whole scientific would follow the progress of the first successful clone, Dolly the sheep. Altogether Dolly lived for six years, half the length of the life of the original sheep.T: Now let me explain something about the appositive clauses. The appositive clause is a clause used as an appositive. The clause is an explanation to the noun before. The appositive clause belongs to noun clauses. Most of the appositive clauses may be introduced by the conjunction that.A content clause is frequently in apposition with such nouns as fact, news, idea, thought, question, reply, report, remark, hope, belief, suggestion etc.Some examples:Nobody shares my belief that he was mad.My suggestion that he was mad was not accepted.They are familiar with the opinion that all matter consists of atoms.Where did you get the idea that I could not come?We haven’t yet settled the question where we are going to spend our summer vacation.The suggestion came from the chairman that the new rule should be adopted.T: The words the fact are often inserted in front of an object clause when the clause cannot be conveniently connected with the verb either directly or by means of the representative it.This cannot hide the fact that he is growing old.We must face the fact that we are living in a revolutionary world.Some supplements:同位语从句与that引导的定语从句1) 从先行词看同位语从句与名次之间在逻辑上是“主语+be+表语”的关系。
