Recently there was a major discovery in the scientific research—the mapping of all DNA in a human gene is complete. Several years ago, it seems an impossible task for scientist to accomplish. All this progress in science leads us to believe that the day when human being will be cloned is not far away. Human cloning has always been a topic of argument in terms of morality (道德) or religion.
Taking a look at why cloning might be beneficial, among many cases, it is arguable that parents who are known to be at risk of passing a genetic limitation to a child could make use of cloning. Moreover, cloning would enable women who can't get pregnant to have children of their own.
Cloning humans would also mean that organs could be cloned, so it would be a source of perfect transfer organs. This surely would be greatly beneficial to millions of unfortunate people around the world who are expected to lose their lives due to organ problems. It is also arguable that a ban on cloning may be unlawful and would rob people of the right to reproduce and limit the freedom of scientists.
However, arguments against cloning are also on a perfectly practical side. Primarily, I believe that cloning would step in the normal "cycle" of life. There would be a large number of same genes, which reduce the chances of evolution, since it may be difficult for living creatures to naturally adapt to the ever-changing environment, which will result in ultimate disappearance. Furthermore, cloning would make the uniqueness that each one of us possesses disappear. Thus, leading to creation of genetically engineered groups of people for specific purposes and, chances are that those individuals would be regarded as "objects" rather than people in the society.
Scientists couldn't surely guarantee that the first cloned humans will be normal. Thus this could result in introduction of additional limitations in the human "gene-pool".
Regarding such arguable topics in "black or white" approach seems very innocent. We should try to look at all "shades" of it. I believe that cloning is only legal if its purpose is for cloning organs; not humans. Then we could regard this as for "saving life" instead of "creating life". It is believed that cloning humans is morally and socially unacceptable.

Getting rid of dirt, in the opinion of most people, is a good thing However, there is nothing fixed about attitudes to dirt.
In the early 16th century, people thought that dirt on the skin was a means to block out disease, as medical opinion had it that washing off dirt with hot water could open up the skin and let ills in. A particular danger was thought to lie in public baths. By 1538, the French king had closed the bath houses in his kingdom. So did the king of England in 1546. Thus began a long time when the rich and the poor in Europe lived with dirt in a friendly way. Henry IV, king of France, was famously dirty. Upon learning that a nobleman had taken a bath, the king ordered that, to avoid the attack of disease, the nobleman should not go out.
Though the belief in the merit(优点) of dirt was long-lived, dirt has no longer been regarded as a nice neighbor ever since the 18th century. Scientifically speaking, cleaning away dirt is good to health. Clean water supply and hand washing are practical means of preventing disease. Yet, it seems that standards of cleanliness have moved beyond science since World War II. Advertisements repeatedly sell the idea: clothes need to be whiter than white, cloths ever softer, surfaces to shine. Has the hate for dirt, however, gone too far?
Attitudes to dirt still differ hugely nowadays. Many first-time parents nervously try to warn their children off touching dirt, which might be responsible for the spread of disease. On the contrary, Mary Ruebush, an American immunologist(免疫学家), encourages children to play in the dirt to build up a strong immune system. And the latter position is gaining some ground.
