9、母想要克隆孩子，要么是想为面临死亡威胁的孩子提供移植器官，要么是想代替那个孩子。Adults who for a variety of reasons might want to clone themselves.成年人出于各种原因想要克隆自成年人出于各种原因想要克隆自己。己。For example Leaders in most countrires already prohibit human cloning,began examining the moral implications of cloning other species. Some experts are concerned

10、 about the creation of a new land disrespected social class:“the clones”.But From the preceding description we can see that cloned animals can bring human beings many benefits , such as the production of food, medicines, organs, to save the endangered animals and so on. However, human cloning, there

11、 are various aspects of problem related to the ethical, psychological, social patterns and then on, which requires human beings to continue to explore. There still remains much more disadvantages of the application of cloning reproduction of human being and animals. We should be extremely cautious o

12、f what we do and thus remember we will sure be respondible for all the results created by ourselves! SoIs clone good or not? Research advances over the past decade have told us that, with little work, we humans can clone just about anything we want, from frogs to monkeys and probably even ourselves!

13、 So, we can clone things, but why would we want to? Lets look at some of the reasons people give to justify cloning. Some other uses of clone Rescue endangered animals. Provide experimental animals and organizations. Produce new productions for humans. Cure and go against some genetic diseases. Cont

14、ribute to high level new medicines.Some other objections May bring some new diseases which is It can be abused by some dangerous organizations. A big hammer to traditional family structure and relationship. Hurt those who are cloned. Using the clone technology may in the rescue precious endangered a
