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 WTO 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. Pretty cool, answer the pro-cloners
