阅读理解。 A: Recently, the word 'clone' has appeared very often in the newspapers. Do you know its meaning? B: Not exactly. I read a report in yesterday's newspaper. It said a Scottish scientist had successfully cloned a lamb named Dolly. It was the first time that a cloned lamb had been made from an adult sheep. A: Actually, the word 'clone' means to produce the 'same' animal by taking cells (细胞) from an adult one. I think, if we know how to do cloning, we need only keep a small number of sheep, cows and horses. B: (A) It's said that recently there have been some people who ever wanted to clone humans. A: It seems interesting. (B) 但你觉得那样做可能吗? B: No, I don't think so. First, I think we can't clone a dead person because the cells in his body have been dead already. A: Then can we clone a living person? B: Again no. You might clone yourself one after another, but it is only a copy, not a real you. It is only something, not a human. A: Well, you mean that a real human can speak, think and create, and these abilities(能力) can't be cloned? B: That's right! I think the main purpose of  Dr. Ian Wilmut, the 'father' of Dolly, is to make better animals, and it has nothing to do with human cloning. 根据短文内容,回答下列问题。 1.
