Unit 8Part I Pre-Reading TaskScript for the recording:A Clone of Our OwnWill humans be the next clones? The technology still has a long way to go before it's considered safe to try on humans. But even if it were safe, would it be right? Let's hear what Professor Hank Greely of Stanford University has to say on this topic .Interviewer: When will we clone a human?Greely: That's not a simple question. I think we have to ask ourselves: is there something about the technology that is so wrong or so evil that it shouldn't be used at all? Or should it be judged according to its intended uses? Interviewer: What are acceptable uses?Greely: We really need to distinguish between different types of cloning. If we use cloning to grow a new liver, I don't think many people will have problems with that - as long as it's growing a liver and not taking a liver from a cloned person. Human reproductive cloning is much trickier. Interviewer: Why?Greely: Safety. There's still a very low success rate. With Dolly, the first cloned lamb, 29 treated eggs were implanted in sheep to get one Dolly. We don't worry too much about sheep miscarriages or about deformed lambs being born. But we would with humans. And we wouldn't know if a human clone would be healthy. Interviewer: Dolly appears to be healthy. Why wouldn't a human clone be so?Greely: There may be cell changes that are initially invisible and only show themselves as the clone ages. There's also a problem with the ends of chromosomes in cells, whichshorten until the cells can no longer reproduce. We know that Dolly's chromosomesare shorter than those of other sheep her age, and we don't know what that means yet.- 188 -Appendix IInterviewer: Suppose human cloning was safe. In what situations do you see cloning being used?Greely: Helping parents who are having difficulty having children would be one area. Interviewer: Are there other situations where it might be acceptable to create a human clone?Greely: A situation where parents want to create a new child to be a bone marrow donor for an older sick child. That's a real tough one. But that issue might never arise if we succeed in growing bone marrow outside the body. Another situation is cloning a child who has accidentally died. I think that's disturbing. But I've never been in that position and so I don't feel comfortable saying whether that's a good application or a bad application of the technology. Interviewer: What about cloning a Hitler or Michael Jordan ?Greely: I think we can dismiss those as bad or even silly applications. Interviewer: Is there anything else you'd like to say about the future of human cloning?Greely: Even if cloning humans were safe and we as a society had decided it was right and proper for reproductive purposes, I don't think we'd see a lot of clones. The oldfash-ioned way ofmaking babies has a lot going for it: It's easy, traditional, well understood, and occasionallyeven pleasant. People are not going to give up sex anytime soon.Part II Text ATexf Organization 1.Appendix I- 189 -2.Vocabulary1) residence 2) gave birth to3) fuse 4) primitive-5) genes 6) compromise7) mixture 8) union9) beforehand 10) started out11 ) comment , 12) catalog13 ) theoretical 14) all the world15 ) opposed1) calls for 2) woke up3) took up 4) runs out of5) sums ... up 6) broke down7) lashed out at 8) has grown into1) The hillside facing the Pacific is dotted with colorful houses.2) The present Labour government inherited a weak economy from the Conservative govern-- 140 -Appendix 1II.

Opinions differ widely as to whether human cloning should be prohibited.True, human cloning clearly has much to offer. By using cells from the patient's own body to grow organs to replace diseased parts, the problem of rejection can be avoided. This might prove useful, for example, in fighting leukemia through bone marrow transplants. But what about making an identical copy of a human being?Ian Wilmut, who created Dolly the sheep, finds the idea offensive. Professor Hank Greely at Stanford also finds the suggestion deeply disturbing. For one thing, the technology is far from perfect. There may be lots of miscarriages and deformed clones. What shall we do with them? Shall we keep the healthy clones and just kill off the ones with a deformed body or defective brains? That, I am afraid, would offend the religious beliefs of a great many people. For another, even if the- 142 - Appendix Ic5. b6.

The government should enact laws to prohibit it before it is too late. Non-reproductive cloning, on the other hand, should be encouraged. It may mean hope to many who are waiting desperately for organs for transplantation to save their lives. If used wisely the technology may eventually free humans from many kinds of suffering that today seem unavoidable.(273 words).。
