　Cloning (克隆) : Future Perfect?

　　1. A clone is all exact copy of a plant or animal produced from any one cell. Since Scottishscientists reported that they had managed to clone a sheep named Dolly in 1997, researchinto cloning has grown rapidly. In May 1998, scientists in Massachusetts managed to createtwo identical calves (牛犢) using cloning technology. A mouse has also been clonedsuccessfully, But the debate over cloning humans really started when Chicago physicistRichard Seed made a surprising announcement: "We will have managed to Clone a humanbeing 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 US thePresident announceD. "We will be introducing a law to ban all human cloning and manystates in the US will have passed anti-cloning laws by the end of the year. "

　　3, Many researchers are not so negative about cloning, They are worded that laws banninghuman cloning will threaten important research. In March, The New England Journal ofMedicine called any plan to ban research on cloning humans seriously mistaken. Manyresearchers also believe that in spite of attempts to ban it, human cloning will have beconieroutine 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 beenbombarded (轟炸) with newspaper articles, television shows and films, as well ascartoons. Such information is often misleading, and makes people wonder what on earth thescientists will be doing next.

　　Within the next five to ten years scientists will probably have found a way of cloninghumans. It could be that pretty soon we will be able to choose the person that we want ourchild to look like. But how would it feel to be a clone among hundreds, the anti-clonersask,. Pretty cool, answer the pro-cloners (贊成克隆的人).
