【回答】
Many people object to cloning humans, and some countries even forbid scientists to do research into human cloning. They feel cast down because it is not morally reasonable. However, other countries quite differ. They are in favour of medical cloning. Actually many countries are undertaking it, and they have accumulated much experience and obtained great breakthroughs. Everything has two sides, so we should not resist it completely.
