Now, work in groups to discuss the following questions.1.How would you treat human clones?2.Do you think they should have legal and political rights, such as getting married or voting?3.Do you think they are separate people or part of the donors?2 While Listening (P54)The Ss are asked to read fast the question and multiple answers to find out the listening points first, and then listen to the tape twice to choose the best answer.“Please open your books at page 54. Before you listen to the tape, please read fast the questions and multiple answers to find out the listening points. Pay more attention to these important points while listening.

They argued that serious illnesses and people who w losing their ability to move or think could be helped by medical cloning. They explained that the procedures would be safe, quick and with no problems for the patients. They quoted that 67% of American citizens are for it to support their idea. Their arguments were very convincing.The arguments put by the team opposing medical cloning were less strong. They argued in two ways. The first reason was that the procedures were not yet secure. Their second reason was that it took many tries and many potential animals had to be killed to produce one useable embryo for resear ch. They explained that man European countries don’t allow medical cloning research because of this. They quoted Pope John Paul Ⅱ. But their arguments were not so convincing.At the end of the debate the audience we left with a feeling of hope. They realized that diseases that seem terrible today may be able to be cured soon. Many people were excited and happy when they left they Hall .The writer of this article was among them!。
