Lead students to learn the unit while thinking about the relationship between the title of the unit Science and nature and cloning technology.Step2 Sharing information Show the four pictures one by one, each of which shows a successfully cloned animal. As to the four pictures, we conduct the following activities. 1. Interview one student about his feeling towards cloned animals by asking the following three questions: If you happen to have a cloned cat, how would you feel?

Interview another student about his feeling towards a “cloned him”. Then ask the other students if they would like to see a “cloned him” and why.Step 3 DiscussionGet students to form groups of four or six to discuss the further questions: 1. From just these pictures, can you identify the differences between the cloned animals and normal ones? 2. In your opinion, what might be the differences between these cloned animals and normal ones? Can these animals lead a normal life as normal animals?Period2 Reading1 ComprehensionTeaching Objectives1. To think more about the relationship between science and nature.2.
