　　Check the homework. Encourage students to share their sources relevant to cloning technology with the whole class. Tell students that cloning has been the subject of scientific experiments for years. The recent success in cloning animals has resulted in fierce debates between scientists, politicians and public.

　　Step2 Reading strategy

　　Get students to go through the reading strategy, and make sure that everyone of them understands how to work out the meaning of these scientific terms.
