Unit 2 CtoningThe First Period Warming up and Reading Teaching goals1.Enable the students to describe cloning: What is theadvantages of cloning?2.Help the students analyze the writing techniques of thearticle.Teaching procedures Step I Warming up一：You can imagine how rapidly the modem science and technology develop. I think most of you must know something about space traveling, submarine exploration, robot, maglev train, gene engineering etc. But in recent years, a hot topic, cloning is often mentioned, especially when the cloning Dolly the sheep appeared. You may have first heard of cloning when Dolly the Sheep showed up on the scene in 1997. Cloning technologies have been around for much longer than Dolly, though.First things first, what is cloning and a clone? The dictionary says cloning is the technique of producing a genetically identical duplicate of an organism. A clone is said to be all descendants derived asexually from a single individual, as by cuttings, bulbs, by fission, by mitosis, or by parthenogenesis reproduction. In fact, in our daily life, this happens often. For example, gardeners take cuttings from growing plants to make new ones. You often see that your mother picks a small branch from a growing plant to make a new one. If she likes this kind of flowers, she can do cloning. Cloning also happens in animals or human beings when twins identical in sex and appearance are produced from thesame original egg.Discussion 1. Do you want to be cloned or not? Why?2.Can you tell me the advantages of cloning?3.And what is the disadvantage?二:Look at picturesLook at the pictures and discuss which ones are natural clones and which ones are man 一made. Then explain how they differ.Step II Pre-reading(Before class, ask the students to search for some information about this topic. ) Now show your questions on the screen, and then let them discuss with each other.Now please work in pairs and discuss about cloning. Then list the questions you want to find out. Share your list with your partner.Questions about cloning:1.What is a clone?2.How is a clone produced?3.What benefits can humans gain from cloning?4.What problems may arise when humans are cloned?5.Should we clone human?6.Could cloning replace sex as the means of creating new human life?7.Could a parent clone a child who is dying of a terminal illness?Suggested answers:1.It is a way of making an exact copy of another animal and plant.2.This happens in plants when gardeners take cuttings from growing plants to make new ones, and when small parts of a plant are taken and gown in a laboratory. Italso happens in animals when twins identical in sex and appearance are produced from the same original egg.3.It can help cure disease and can help couples who have no baby to bear a new baby.4.There may be more bad people like Hitler.5.In my opinion, I do not agree, for it may cause many moral problems.6.No. Because cloned human has the same quality as the real human, natural born baby's quality is higher than his parents.7.No. The cloned baby also has the disease.Step III Fast- readingHave you not the answers of your questions? Now please skim the passage fast to obtain a general understanding of the whole passage into several parts and find out the main idea of each part.Show the following.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.Step IV Careful-reading1.Ask the students to read the passage carefully to finish exercise Ion page 12 in the students, book.2.Check the answers.3.Finish exercise2on page 12 in the students' book.4.Check the answers5.Explanationl.)It is a way of making an exact copy of another animal and plant.全句汉语意思:它是一种精确复制另一个动物或植物的方式。
