Teaching procedures

Period 1 Reading Step 1. Warming up A. Lead in: If necessary, introduce something about cloning by questions and answers: The three types of cloning: 1. recombinant DNA technology or DNA cloning; 2. reproductive cloning; 3. therapeutic cloning B. Discuss the pictures on P10, then finish the warming-up exercises.

Questions about cloning: What’s cloning? How is a clone produced? What benefits can humans gain from cloning? What problems may arise when humans are cloned? Should we clone human? Could cloning replace sex as the means of creating human life?

Step 2. Reading Task 1: Ss scan the passage and try to get the main idea of each paragraph: Suggested answers: Para. 1 Cloning is a way of making an exact copy of another animal and plant. Para. 2 Cloning has two major uses. Para. 3 The problems of Dolly. Para. 4 The effect of Dolly Para. 5 It is forbidden to clone human being. Task 2: Ss read and finish Ex 1-3 on page 12

Period 2. Language learning Step 1. Revision Ss retell the text. Step 2. Language points Explain the following sentences: it is a way of making an exact copy of another animal and plant. 它是一种精确复制另一个动物或植物的方式. Dolly’s appearance raised a storm of objections and had a great impact on the media and public imagination. 多利的出现引起了一场反对的风暴,并且对媒体和公众思想产生了很大的冲击. However, scientists still wonder whether cloning will help or harm us and where it is leading us. 然而科学家一直致力于研究克隆到底会有助于我们还是会伤害我们, 它将会把我们引向何方. I would like to suggest that medical cloning is not as simple an issue as many colleague claims. 我认为医用克隆技术并不像很多同事们所说的那么简单。

5． If you believe that human life comes into existence as soon as the cells start to grow, then the practice of removing human stem cells from an embryo kills it. 如果你认为人的生命在细胞开始生长时就形成了，

那么从胚胎中去除人体干细胞就会杀死这些胚胎。
