Listening：Is Cloning Cruel? RB:

Xiao Qing, do you think cloning is ________? XQ:

What do you mean by that? The scientists are doing a wonderful job and soon they may be able to bring people’s favourite pets back to life.

RB:

Yes, I know. But doesn’t that seem strange to you? Is it worth it? It took _________ experiments before Dolly was successfully cloned. Think of all those live cells and eggs that died in order for Dolly to be born. I don’t approve of that! XQ:

But Rachel, be _____________. Isn’t it always like that with a new science? This is the way you learn to do things better. RB:

I suppose so —

but they make the animals do unnatural things. One poor cow was made to give _______ to a bison. What was the poor creature to think when it saw its baby? XQ:

I don’t quite understand why so many people are against cloning. I think the scientists need a bit of _________.Think of the benefits. Cloning may help medical science to produce cures for serious _________. RB:

Yes, I know and I agree with that. It is just that I don’t agree with the methods. XQ:

Why not?

RB:

Well, I think it’s a_______ end. Dolly the sheep was “middle-aged” when she was born because her DNA came from a middle-aged “mother”. Cloning your grandmother would mean the new baby started life as an old lady! XQ:

Really? I never thought of that! RB:

And it ________ the species. Cloning means that there's less variety in the species.So the animals may not be able to_______ a particular illness and they might die out. XQ:

Oh dear! And that was just what you and I were trying to avoid. In __________ of all these, don’t you think scientists would still be able to solve the problem?

Summarize Be Careful about Cloning After a series of initial experiments and corrections, the scientist’s hard work paid off when the twin clone turkeys were hatched with normal feather and claws. This breakthrough possibly enabled people to bring their adored pets back to life. However, it bothered him from time to time that their health was in poor condition because they were unable to resist illnesses. This drawback cast him down. Merely 2 weeks later, the clones and their carrier died, which struck frustration into his heart. He retired before he attained his ambition and became a member of an opera chorus to relieve his depression. Shortly afterwards, the media published a conservative argument objecting to cloning owing to moral problems, and suggested the constitution include compulsory regulations to forbid obtaining commercial profits from cloning. When interviewed, the scientist stared at the decorations on the ceiling, thinking for a while, and then said, “I’m not in favour of any arbitrary assumption, but undertaking cloning does differ from the straightforward procedure of making loafs out of flour. Until we accumulate enough exact knowledge, any practice is in vain and is bound to fail. Altogether, being more careful is reasonable or we may walk into a side road.”(Translation)
