A sample version:
Should Medical Cloning be Allowed
A Debate at Xinhua Middle School
Yesterday there was a very exciting debate at Xinhua Middle School about whether medical cloning should be allowed or not .After a lively discussion a vote was taken and the side arguing for medical cloning won.
The arguments for medical cloning were very strongly put by the team supporting the motion. They argued that serious illnesses and people who w losing their ability to move or think could be helped by medical cloning. They explained that the procedures would be safe, quick and with no problems for the patients. They quoted that 67% of American citizens are for it to support their idea. Their arguments were very convincing.
The arguments put by the team opposing medical cloning were less strong. They argued in two ways. The first reason was that the procedures were not yet secure. Their second reason was that it took many tries and many potential animals had to be killed to produce one useable embryo for research. They explained that man European countries don’t allow medical cloning research because of this. They quoted Pope John Paul Ⅱ. But their arguments were not so convincing.
At the end of the debate the audience we left with a feeling of hope. They realized that diseases that seem terrible today may be able to be cured soon. Many people were excited and happy when they left they Hall .The writer of this article was among them!
