S: Edison, dinosaurs, Japanese wolf, Einstein. T: Do you want to clone Hitler? S: No. Hitler is a dangerous person. T: If some terrorists master this clone method, they may bring disasters. All your choices are excellent. Today we will learn another passage about cloning, from which we will know whether we can bring dinosaurs back to life.

Ask the students to go through some facts of cloning. T: From these facts we know human beings have achieved great progress in cloning. Now read the text carefully to get the answers for these questions: what animals have people cloned? S: Frogs, mice, cows, sheep, bison, cats, and dogs. T: Good job. Answer the question: What are the common characteristics of these animals? Ss: They are nowadays animals. T: Yeah, I think you must have seen the film Jurassic Park, in which a scientist clones several different kinds of extinct dinosaurs. Can we

really clone dinosaurs now? Let the students turn to page 15 and then read the text quickly.

S: We cannot clone dinosaurs, because it’s difficult for us to get its DNA. T: Good job. It’s only a dream. Dinosaurs disappeared 65,000,000 years ago.

Like most people, there was a time that I

dreamed of being an excellent student in my

English after entering senior middle school, but

my English was very poor then. To catch up my

classmates, I followed my friend advice and took

some measures.

For an instance, I made pen-friends with

some foreign students so as to practise my

speaking English and improve my written

English.

Step 7 Homework T: Write down your feelings and attitudes towards clone. Combine them into a composition.

Sample version 1:

In my opinion it is wrong to clone human beings. If my parents decide to have a clone made of me, I will feel very sad and I will never accept the clone as a member of my family or as my friend because I think it is unfair to natural things.

We are all sons of nature, birth or death is a natural thing. The day we born, it destined we are independent. Nobody has the right to change ourselves. If one day I were to be cloned to another person, he would kill me, because I lost some original characters. I hope we should respect human beings, and not change any original things. Sample version 2:

I think the cloning represents the progress of the mankind. But it still has many problems to work out, the law, the ethic and especially the goals and purposes for cloning. However, we are actually doing much of this research for the improvement of life for humans. We should get benefit from cloning.

In China, the government has put out written policy on human cloning. It has officially banned research on human cloning for reproduction purposes, but allows cloning on embryonic stem cells and remedial cloning. As we all known, everything can’t be perfect. We should treat the cloning with correct attitudes. We should know the advantages and disadvantages of cloning.
