According to an English newspaper, scientists could begin cloning human embryos in Britain in 2001. It is understood that the government has already agreed to use Frankenstein’s technology, believing the benefits are more important than ethical (伦理的)concerns .Researchers think it will be possible to grow brain tissue to cure the diseases that are likely to get worse as time passes like Alzheimer’s , and produce “spare part” organs like hearts and kidneys for transplant (移植). Ministers are aware that the change in the law will be as controversial as the law which legalized abortion (堕胎)more than 30 years ago. Some politicians reacted angrily , arguing that the government had already made up its mind without discussion. Church leaders and anti-abortion campaigners have long expressed their horror at the plans, arguing that even the earliest embryos are forms of human life.They believe that getting an embryo from cells is morally unacceptable . And it will also cause arguments about how far scientists should interfere with nature and lead to accusations that they are “playing God”. The cloning of human embryos to provide spare parts is regarded by most experts to be the most important step forward in the 21 st century medicine. Scientists say treatment of diseases such as Alzheimer’s and Parkinson’s will be the first application of cloning. The ability to clone embryos was first achieved by scientists in Scotland in the late 1990s and now the ability to grow stem cells into tissues and organs is being developed by American researchers. Combining the two technologies will mean an end to long waits for organs from donors and problems caused by rejection (排异反应) of transplanted tissues by the body. Ian Wilmut, the man who cloned Dolly the sheep, has warned that British experts will go to America, where such work is legal, if the government does not permit it. 小题1:The government has decided to allow scientists to clone human embryos because they think that ____.
