Unit 3 Science versus nature Cloning: where is it leading us?Cloning has always been with us. It is a way of making an exact copy of another animal or plant. In 1996, the scientists succeeded in cloning Dolly the sheep. On the one hand, the whole scientific world paid close attention to the growth of the first successful clone, Dolly the sheep.In general the scientists were praised for their wonderful scientific breakthrough. On the other hand, Dolly's appearance raised a storm of objections. It suddenly opened everybody's eyes to the possibility of using cloning to produce valuable tissues and organs that could be used to save human lives.However, some scientists have adopted the technology with the intention of cloning human beings although it is illegal in the majority of countries. Human cloning has aroused a lot of anxiety.Many people insist that if we toy with life, we might create problems.From my point of view, I am not in favour of human cloning. We must be responsible for the consequences of our actions. We ought to be very cautious about human cloning. When we make a decision whether we clone human beings or not, everything should be taken into consideration.In brief, we can push ahead with the technology of cloning to meet our needs instead of destroying our life.克隆：将我们引向何方？克隆一直与我们同在。这是一种用来生产与原型完全相同的动植物的方法。1996 年，科学家们成功克隆出多莉羊。一方面，整个科学界都在关注着首例成功的克隆动物多莉羊的成长。从总体上来说，科学家们因为其杰出的科学突破而得到了人们的称赞。另一方面，多莉的出生引起了一阵强烈的反对。它突然打开了人们的眼界，看到了有可能利用克隆技术来生产能够用来拯救人类生命的宝贵的组织和器官。然而，有些科学家已经采用这一技术目的是克隆出人类，尽管在大部分国家这是不合法的。克隆人类已经引起了很多担忧。很多人坚持认为如果我们把生命当作儿戏，我们可能会制造很多问题。从我个人观点来看，我不赞成克隆人类。我们应当为我们行为的后果负责。我们应当谨慎对待克隆人类。当我们决定是否克隆人类的时候，我们应该把各种因素考虑在内。简言之，我们可以努力推进克隆技术来满足我们的需要而不是破坏我们的生活。
