Today we will learn something about cloning together. The reading passage is made up of a newspaper article about cloning and two readers letters. We will be given information about how cloning is being researched and the different attitudes towards it.Step3 Fast readingA. Answer the following questions. 1.What is cloning?Cloning is producing an exact copy of a plant or an animal using its cells.2.Is Pauline Carter for or against human cloning?She is against human cloning.B. Match each paragraph with its correct main idea.Para1 An announcement about the first cloned human embryo caused much debate.Para2 The first cloned mammal was Dolly. Para3 Ian Wilmut is shocked that some scientists are considering cloning human beings.Para4 A woman wants to have a cloned baby.Para5 Cloning human embryos is illegal in many countries, but some scientists still want to clone human beings.Para6 Chinese scientists continue to research ways in which cloning can benefit mankind.Step4 Detailed reading Read the two letters carefully, and judge whether the statements are true or false:Pauline Carter thinks: 1.The nature will pay back if we toy with nature. (T) 2.We should clone fewer babies to reduce Earths population. (F) 3.The lady who cannot have a baby can adopt an orphan, but not have a cloned baby.
