on humans. But I wouldn't let them just clone people as they wished; they would only be able to use their knowledge and skills in certain situations - for example, for people who lost a child and weren't able to have another.

Sample version 2:

If I had the power, I would ban cloning for several reasons. Firstly, it is against nature and dangerous. Any living things have life and death recycle periods, which promote the evolution of life. The cloning technique is extremely risky right now. An abnormal baby would be a nightmare that comes true. And people are worried about the possibility that the genetic material used from the adult will continue to age so that the genes in a newborn baby clone could be 30 years old or more on the day of birth. Also monsters may be created by mistake. Secondly, people are afraid of that scientists will create thousands of copies of the same person. There are powerful leaders in every generation who will seek to abuse this technology for their own purposes. Going ahead with cloning technology makes this far more likely. What would happen if Hitler was cloned? That would mean more severe disasters and destruction upon human civilization. Thirdly, cloning will result in high emotional risks. Just think: a child grows up knowing her mother is her sister, her grandmother is her mother. Her father is her brother-in-law. Every time her mother looks at her she is seeing herself growing up. The family environment and relationship will be totally different. What kind of pressures will the child feel?

All in all, I would determinedly ban cloning if I had the power.

Sample version 3:

If I had the power, I would encourage cloning. There are several reasons. Firstly, cloning will be beneficial to humans. For example, if a couple can't have children, cloning could help give them a child. Secondly, we could use cloning to cure illnesses. For example, if there is something wrong with some part of a human body, we could clone a healthy one to replace it. For another, if a child is seriously ill or disabled, we could clone another one. Thirdly, clone technology could be used in other ways. For example, we can save the endangered animals by cloning.

In a word, cloning technology has a promising future. I would encourage it if I had enough power.
