S2: I agree with you. But I am happy to accept Dodo bird because it is friendly and not harmful. I like gentle animals. It can also lay large eggs and its meat is tasty, but I don't think I will eat its meat.

...

T: From your answers I think these animals are all useful and they all should be restored to the earth. At the same time, we should try our best to protect them. Do you agree with me?

S: Yes.

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 Ⅵ 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.
