你班同学在英语课上就 Is cloning good or bad?这一话题展开讨论.假如你是小组长,请根据小组讨论的结果用英语写一份报告,并陈述一下自己的看法.要点如下：
1.克隆技术是科学史上的一个重大突破
2.克隆技术在用来治疗人类的某些疾病,用来防止某些濒危的物种的美绝方面有积极的意义,但这项技术被一些科学家用于克隆人,由此引发一系列伦理道德问题,其危害将是巨大的
3.我们坚决发对克隆人
注意：1.报告必须包括所有的要点,可适当增加细节,是内容连贯完整
2.词数：150左右
3.文章句首已给出,但不计入总词数
On behalf of our group,i'dlike te give brief summary of our discussion on the topic"Is cloning good or bad?"

这个问题是有双面性的．绝对说克隆好或者坏都是片面的．应该说,克隆对人类乃至整个生态系统来说都是既有有利的方面,也有有害的方面．
首先,克隆对人类而言最敏感和重要的话题就是克隆人了．但是这方面的禁止也只是源自人类的理智的道德底线要求．因为每个国家都有相关的规定,所以如果一个国家没有限制在本国进行克隆人实验,那别的国家顶多也就是舆论上会施加压力．但是却没有办法真正制止．在一些公海,公岛上,克隆人实验可以不受任何人的约束进行．我所知,确实已经有克隆人存在．
如果说这只是传说而已,不一定确实,那也可以用公开的实验说明,韩国曾经有一个研究生在进行人体卵细胞培养时做过类似的实验,结果他在把卵细胞培养到8胚期时终止了实验,因为他觉得”会有可怕的后果”．但是从生理学角度讲,一个卵细胞如果发育到8细胞期,那应该意味着新的生命的诞生．只是细胞数量上比较少而已,但是如果继续培养,这样的胚胎会发育成真正的人．这也就是克隆人的诞生了．
目前,人类反对克隆人只是局限于人类道德规范和道德准则的基础上.有些国家有相关的规定制止,但不是所有的国家都禁止了这一实验．
在二十年前,试管婴儿也被认为是违反人类伦理道德和行为准则的实验,但是在当今社会,试管婴儿已被普遍接受,并且从推行结果来看,新的技术确实给人类带来了可观的经济效益和让更多的人能有机会生育子女．
我想,克隆人不被接受也就是说当今人的思想意识没有办法容忍克隆人的存在．但是人类是不断进步的,我相信大家接受克隆人只是时间的问题．
克隆在其他方面的应用早就被大多数人接受．比如,我们现在打的疫苗基本都是克隆得到的,真正做到了降低成本,安全有效的目标．如果没有克隆,也许很多疾病还是致死疾病,而疫苗的价格也不会被大多数人所接受和能够承担．
器官的克隆也早已实现．给人们带来了许多益处．
其次．可以说说克隆的局限性.希望大家不要狭隘地理解克隆,其实在当今社会中克隆的东西无处不在,医疗药品就不用多说了,其实很多我们吃的水果,蔬菜等也是克隆的．克隆的含义就是无性繁殖．把一个果树的枝条插枝成活,从某种意义上来说也算克隆．而现在,果园中到底还有人用苹果的种子种苹果树吗?也许大家会觉得可笑了．希望大家不要误解克隆的就都是坏的．要广泛的理解克隆的意义．
当然,从生物进化的角度讲,克隆是违背人类进化规律的行为．两性繁殖作为人类在长久的生物进化和物种选择中保留下来的繁殖方式,必然有其优越性和不可替代性．最重要的,就是两性繁殖带来的物种的多样化．简单点说,爸爸和妈妈生下的孩子既有爸爸的基因,也有妈妈的基因,但是克隆作为无性繁殖方式,也就是说只有一方的基因,长久下去,人类的基因多样性,物种多样性会逐渐消失,而生物的进化规律中,只有多样化的物种才更有机会存活,如果抛弃人类现有的发达智力,克隆人也就只是人类灭亡的开始．也就是说,无性繁殖使人类的多样性消失,不能产生更加适应环境的物种,当其他的生物随环境的改变而进化得逐渐更加适应环境时,人类就会被逐渐淘汰．
克隆是很复杂的问题,关于克隆的讨论也是有好有坏．我只是就自己的专业和知识浅谈了一点．更深刻的讨论应该还在进行中．
The problem is that there are two-sided. Absolute say cloning is good or bad one-sided. It should be noted that cloning whole human Ecosystems are not only beneficial, there is also harmful aspects.
First of all, the cloning of human beings in terms of the most sensitive and important topic of human cloning. But this is only prohibited from the human rational and moral requirements of the bottom line. Because every country has the relevant provisions, so if a country does not Restrictions in the country to conduct human cloning experiments, that is, at most other countries will put pressure on public opinion. But there is no real way to stop. In some of the high seas, and the public on the island, human cloning experiments can not be bound by any person to carry out. I Know, there really has been the existence of human cloning.
If we say that this is only legend, but not necessarily true, it can also open the experiment shows that South Korea was a graduate student in human egg cell culture has done a similar experiment, the results of his training in the egg cell to the embryonic period of 8 to terminate the Experiment, because he felt that "there will be dire consequences." Physiology from the point of view, however, if the development of an egg cell to cell 8, that should mean the birth of a new life. Is relatively small number of cells only, but if it continues to Culture, such embryos will develop into a real person. This is the birth of a cloned human.
At present, opposed to human cloning is limited to human ethics and code of ethics on the basis of. Some countries have put an end to the relevant provisions, but not all countries have banned the experiment.
20 years ago, in vitro fertilization is also considered a violation of human ethics and code of conduct experiments, but in today's society, test-tube baby has been generally accepted, and judging from the results of the implementation of the new technology really brought the Considerable economic benefits and allow more people to have the opportunity to have a child.
I think that human cloning is not acceptable to say today's ideology can not tolerate the existence of human cloning. But it is human progress, I think we accept human cloning is a matter of time.
Cloning in other areas of application has long been acceptable to most people. For example, we are fighting for the basic vaccines are to be cloned, and really reduce the cost of safe and effective. If there are no cloned Perhaps a lot of disease or died from disease, The price of the vaccine will not be accepted by the majority and be able to bear.
Cloning organs have long to achieve. Brought many benefits.
This was followed. Can say something about the limitations of cloning. I hope you will not narrow-minded understanding of cloning, in fact, in today's society things everywhere cloning, medical drugs on the Needless to say, in fact, we have a lot of fruits, vegetables, and so is cloning. Cloning is the meaning of cloning. A Fruit withe the cuttings survived, in a sense still cloning. Now, in the end It was also orchard of apples with the kind of apple seed it? Maybe you will think ridiculous. Clone hope that people will not misinterpret are on the Bad. To understand a wide range of cloning.
Of course, biological evolution from the point of view, cloning is against the law of human evolution. Sexes in human reproduction as a long-term evolution and species selection reproduction preserved the way, must have the superiority and irreplaceable. The most important Is brought about by the propagation of gender diversity of species. A simple point that the father and mother gave birth to the child's father both genes, but also her mother's genes, but cloning as a way of cloning, that is only one gene , Go on for a long time, human genetic diversity, species diversity will gradually disappear, and biological evolution of the law, only the diversity of species to have the chance to survive if human beings to abandon the existing well-developed intelligence, human cloning is only human The beginning of the end. In other words, so that the cloning of human diversity disappear and can not have more species to adapt to the environment, with the other biological evolution and environmental changes have to gradually adapt to the environment more, the human will be gradually eliminated.
Cloning is a very complex issue on the cloning debate is both good and bad. I was just on their professional knowledge and a bit of. More in-depth discussions should be ongoing.
