Cloning（克隆）:Future Perlect?1 A clone is an exact copy of a plant or animal produced from any one cell.Since Scottish scientists reported that they had managed to clone a sheep named Dolly in 1997,research into cloning has grown rapidly.In May 1998,scientists in Massachusetts managed to create two identical calves（牛犊）using cloning technology. A mouse has also been cloned successfully.But the debate over cloning humans really started when Chicago physicist Richard Seed made a surprising announcement:"We will have managed to clone a human being within the next two years."he told the world.2 Seed's announcement provoked a lot of media attention,most of it negative,In Europe, nineteen nations have already signed an agreement banning human cloning and in the U.S. the President announced:"We will be introducing a law to ban all human cloning and many states in the U. S. will have passed anti-cloning laws by the end of the year."3 Many researchers are not so negative about cloning.They are worried that laws banning human cloning will threaten important research.In March,The New England Journal of Medicine called any plan to ban research on cloning humans seriously mistaken.Many researchers also believe that in spite of attempts to ban it,human cloning will have become routine by 2010 because it is impossible to stop the progress of science.4 Is there reason to fear that cloning will lead to a nightmare world?The public has been bombarded（轰炸）with newspaper articles, television shows and films, as well as cartoons.Such information is often misleading,and makes people wonder what on earth the scientists will be doing next.5 Within the next five to ten years scientists will probably have found a way of cloning humans.It could be that pretty soon we will be able to choose the person that we want our child to look like,But how would it feel to be a clone among hundreds,the anti-cloners ask.

问答题Practice 1 After nearly a year of emotional arguments in Congress but no new federal laws the national debate over the future of human cloning has shifted to the states. Six states have already banned cloning in one form or another，and this year alone 38 anticloning measures were introduced in 22 states. The resulting patchwork of laws，people on all sides of the issue say，complicates a nationwide picture already clouded by scientific and ethnical questions over whether and how to restrict cloning or ban it altogether. Since l997，when scientists announced the birth of Dolly the sheep，the first cloned mammal，the specter of cloned babies, infants that ate，in essence，genetic carbon copies of adults has loomed large in the public psyche and in the minds of lawmakers. Today, there is widespread agreement that cloning fur reproduction is unsafe and should be banned. Now，the debate has shifted away from the ethics of baby-making and toward the morality of cloning embryos for their cells and tissues，which might be used to treat diseases. The controversy pits religious c6nservatives and abortion opponents, who regard embryos as nascent human life，against patients' groups，scientists and the biotechnology industry.
