关于“克隆”的英语辩论赛
（1） 中文资料
先看看人类对克隆技术的支持与反对人群：
支持者：狂人政客、恐怖分子、野心勃勃的科学家、渴望巨额利益的企业 反对者：各国政府、国际组织、20余亿信仰上帝的教徒（上帝创造人类） 正方：1“克隆人”技术能使千千万万不孕症患者实现做父母的愿望；能使那些痛失骨肉的亲人重温天伦之乐；能为许许多多不治之症找到新的治疗方案；能创造巨大的物质财富和社会效益
2．克隆技术与遗传育种
在农业方面，人们利用“克隆”技术培育出大量具有抗旱、抗倒伏、抗病虫害的优质高产品种，大大提高了粮食产量。在这方面我国已迈入世界最先进的前列。
3．克隆技术与濒危生物保护
克隆技术对保护物种特别是珍稀、濒危物种来讲是一个福音，具有很大的应用前景。从生物学的角度看，这也是克隆技术最有价值的地方之一。
4．克隆技术与医学 重点：病人的福音
在当代，医生几乎能在所有人类器官和组织上施行移植手术。但就科学技术而言，器官移植中的排斥反应仍是最为头痛的事。排斥反应的原因是组织不配型导致相容性差。如果把“克隆人”的器官提供给“原版人”，作器官移植之用，则绝对没有排斥反应之虑，因为二者基因相配，组织也相配。问题是，利用“克隆人”作为器官供体合不合乎人道？是否合法？经济是否合算？
克隆技术还可用来大量繁殖有价值的基因，例如，在医学方面，人们正是通过“克隆”技术生产出治疗糖尿病的胰岛素、使侏儒症患者重新长高的生长激素和能抗多种病毒感染的干挠素，等等。
反方：1克隆技术还不完善。
——克隆羊DOLLY就生病死了
——克隆采用人工手段进行体细胞分离DNA然后再
次结合，有可能出现基因变异。
2违背人类伦理道德。 重点（貌似是）
——克隆人没有传统意义上的父母。
——克隆人没有家庭。
——与某些宗教教义相抵触。
3还没有克隆人相关的法律
——克隆人是否享有所有人类，公民的权利
——有人可能利用克隆人作为廉价劳动力
——某些组织，宗教可能利用克隆人进行活人祭祀
——某些个人，团体可能利用克隆人犯罪。
——克隆人是否属于其克隆行为的实施者，或者其
细胞提供者？
关于克隆人：1.会引起人类的大恐慌，因为有关可怕的克隆人的电影早已把克隆人妖魔化了；
2.会引发道德伦理上的大讨论，因为奶奶的克隆体可能比孙子还小；
3.会引起另一种歧视，因为据说克隆人除非发生基因突变，或者被引入了其他基因从而变成了转基因超人，不然是不会比人更强的。
好处：帮人做事。坏处：如果克隆出比人类还聪明的，有思想的人类将面临灭亡！ 好事.让失去的亲人复活,其他的事不管了。
（2）英文版
正方： Did you ever imagine having a child that is the exact replica of you? Did you ever imagine of having the cure for heart disease or cancer? Well, these fantasies are not far from reach. The way we could reach
these fantasies is through a process called cloning. Cloning is the replication of an exact genetic copy of an organism by use of a somatic tissue (or cell) from the donor organism. Cloning can be used in humans, human organs, or even animals. There are many advantages and disadvantages of cloning.
A benefit of cloning is cloning human organs or body parts. If a person has a dysfunctional liver or
heart then they could get it cloned and get a brand new one. These are some of the benefits of cloning.
Cloning can bring many benefits to the human, such as rejuvenation, helpful for Defective genes, Liver failure, Kidney failure and Leukemia. These disease
are very different to cure, if we use the cloning technology we can change the Gene’s DNA order, so we can save lots of people.
反方：One disadvantage is whether if cloning is ethical. Cloning will bring up a great controversy on whether if
cloning is the “right” thing to do or not. This controversy is currently going on right now and will be even a greater controversy if the government allows cloning. Many people think that nature should just take its course. Other people think that cloning will be a very good thing to society.
Another disadvantage of cloning is that it has not been perfected yet. The cloning of the sheep Dolly had 276 failures before successfully cloning a sheep. With these kinds of figures we should not even go near trying to demonstrate cloning on humans. One more disadvantage of cloning can be studied through the works of Aldous Huxley in his book the “Brave New World.” Huxley illustrates the future with people having “total loss of individuality, creativity, and freedom. ” This is because if humans are then there would be a lot of the same people in the future. An example would be if a person is cloned and was cloned 3 times. This would cause trouble because none of these clones will have anything unique about themselves. The future of cloning is very questionable. As of now cloning is banned in the United States. The government is not supporting the experimenting of cloning through any means.
总结：Someone is going to do it, legal or illegal. But it seems only logical to do it under strict government supervision with the best trained professionals rather than letting some maniacal scientist do it and let his clone run loose. To reduce the risk of having more disadvantages of Cloning, human cloning
should not be prohibited simply because it does not insure immediate benefits, but it should be experimented with for potential future use. In conclusion, cloning is a study in biotechnology that has unlimited possibilities. There are benefits such as cures for diseases and disadvantages such as not perfecting the technique of cloning. Despite this fact, cloning will be an ongoing process and will be tested. Hopefully cloning will not be a downfall to human history but rather a step
closer to a better society.
第二篇：克隆英语主题的
Science and technology of human cloning technology is a big step forward, there is breakthrough. Cloning technology to the following benefits: First, the use of cloning and other bio-technology, changes in crop genotypes, resulting in a large number of disease resistance, insect resistance, saline-alkali and other new varieties, which greatly increase crop yields. The second is to
cultivate a large number of fine varieties of livestock, such as the cultivation of good meat cattle, sheep and pigs can also develop a number of high milk production, and rich in nutrients needed by the body of the cow. Third, a significant impact on health care, such as relying on molecular cloning techniques, find out the gene, have made the molecular mechanisms of
disease; will contain a milk protein drugs to treat hemophilia transgenic cloned sheep, the can better meet the therapeutic needs of people with hemophilia; to seek a wider range of transplant ** source ** organization and the human immune system genes into animals, the human body needs to grow **, can reduce the immune rejection to improve the transplant success rate. Fourth, to protect the environment and endangered animals and plants to reproduce the species cloning technology. Fifth, it is more appropriate for medical research animals, greatly improve the test accuracy and safety.
Lee: 1) cloning technology can become a mother who can not lift the women's pain.
2) promote the implementation of cloning experiments the development of genetics, as "manufacturing" can be transplanted in the body of animals ** opening up prospects.
3) cloning technology can also be used to detect fetal genetic **. The fertilized eggs used to detect various genetic diseases, cloning, the cloned embryo and the uterus in the same genetic characteristics of the developing fetus.
4) cloning technology for the treatment of nervous system damage. Adult nerve tissue does not regenerate, but stem cells can repair nervous system damage.
5) In vitro fertilization surgery, doctors often need more than one fertilized egg implanted in the uterus, from which a selection into the pregnancy stage. But many women can only provide an egg for fertilization. By cloning can solve this problem. The egg can be fertilized for cloning into a number, thus greatly improving the success rate of pregnancy.
At present, the cloning technology developed very rapidly. Governments concerned, private to the cloning of mixed reviews. Cloning techniques have demonstrated the potential applications, including the following four areas: (1) to develop fine breeds and production animals; (2) the production of transgenic
animals; (3) production of human embryonic stem cells for cell and tissue
replacement therapy; (4) Copy of endangered animal species, animal species preservation and dissemination of resources. In the near future, cloning
technology will be used to treat diabetes, stroke, cancer, AIDS, heart disease and other mental illness such as Parkinson's disease, and significantly change the existing theories and treatment ** transplant to humans bring the Gospel. However, the cloning technology, there are also some drawbacks. In theory, cloning technology is still immature; in practice, the success rate of cloned animals is very low, give birth to some physiological or immune individuals show **, and the animal's disability rate is very high and phenomena associated with premature aging. In addition, the cloning technology
(especially the application of human embryos) the impact of ethics and the public's strong reaction to the word limits the application of cloning technology. However, the development of cloning technology for several years that the world is far behind the science and technology major powers, no one has given up cloning research. In my opinion, the great cloning theoretical and practical value is that it encourages scientists to accelerate the pace of research, the cloning technology research and development into a climax, in order to better benefit of mankind.
The medical benefits, it also allows many infertile people realizing their dreams. Now the scientific community to cloning into therapeutic cloning and
reproductive cloning two. The former is the use of cloning human embryonic stem cells **, for medical research, to solve the problem of inadequate **
transplant donor, which is the international scientific community and the ethics of community support, but there is a premise that embryos for therapeutic cloning can not exceed pregnancy 14 days of the boundaries. As for reproductive cloning, known as human cloning.
Cloning is the world's advanced technology, it is undeniable cloning bring us benefits. We can clone a part of some smart people, so that their talents to the benefit of mankind. You can clone themselves, so that "their" first cold with, until his body parts when problems arise Take the "own" ** into themselves so that they extend life. You can also clone, human cloning ** to let some people in need. In fact, we should not discriminate against human cloning, human cloning is actually human, to some extent, the cloning is more pure than our people. Some people say that anti-cloning technology to bring disaster to mankind will eventually show, I think it is wrong, we cloned and live with his childhood and human interaction, with human habits and ideas, and ordinary people is not respectively, and therefore, we should not discriminate against
human cloning, as we should not discriminate against AIDS patients the same. Significantly contributed to human cloning technology and cultural
development. Clone can make a great contribution to mankind, it not only effectively high-value livestock breeding, to save rare animals, but also the study of cancer biology, immunology research, the study of human life there can not be underestimated. However, human desires are not easily met. From the successful cloning of animals, humans naturally think of human cloning.
It is for the benefit of mankind. The cloning technology, "therapeutic cloning" will be in the production of transplants and overcome disease, etc. ** breakthroughs, biotechnology and medical technology to bring about
revolutionary change. For example, when your daughter needs a bone marrow transplant and no one can provide for her; when you are unfortunate enough to lose 5-year-old children can not get rid of the pain; when you want to raise their children and unable to have children ... maybe you can appreciate the cloned great scientific value and practical significance. Research and therapeutic
cloning complete human cloning experiments are complementary and mutually reinforcing, therapeutic cloning is to complete the end point of human cloning appears to be correct if used, they can and should bring to human society to the Gospel.
In general, the advantages of cloning include:
First, the use of cloning and other biotechnology, plant and replicate good traits to be improved, changed crop genotypes, resulting in a large number of disease resistance, insect resistance, saline-alkali and other new varieties, which greatly increase crop yields. The second is to cultivate a large number of fine varieties of livestock, such as the cultivation of good meat cattle, sheep and pigs can also develop a number of high milk production, and rich in
nutrients needed by the body of the cow. Third, a significant impact on health care, such as relying on molecular cloning techniques, find out the gene, have made the molecular mechanisms of disease; to ** seek a broader source of transplant, the organization and the human immune system ** the gene into the animal body, the body needs to grow **, can reduce the immune rejection and improve transplant success rate. Fourth, to protect the environment and endangered animals and plants to reproduce the species cloning technology. Fifth, it is more appropriate for medical research animals, greatly improve the test accuracy and safety.
克隆技术是人类科学技术上的一大进步，有突破性意义。克隆技术的应用大致有以下好处：一是利用克隆等生物技术，改变农作物的基因型，产生大量抗病、抗虫、抗盐碱等的新品种，从而大大提高农作物的产量。二是培育大量品种优良的家畜，如培养一些肉质好的牛、羊和猪等，也可以培养一些产奶量高，且富含人体所需营养元素的奶牛。三是对医疗保健工作产生重大影响，如依靠分子克隆技术，搞清致病基因，提出疾病产生的分子生物学机制；将一头奶中含有治疗血友病的药物蛋白的转基因羊进行克隆，则可以较好地满足血友病人食疗的需要；为**移植寻求更广泛的来源，将人的**组织和免疫系统的基因导入动物体内，长出所需要的人体**，可降低免疫排斥反应，提高移植成功率。四是为保护环境和濒危动植物，以
克隆技术再现物种。五是为医学研究提供更合适的动物，大大提高试验的精确度和安全性。
利:1) 克隆技术可解除那些不能成为母亲的女性的痛苦。
为“制造”能移植于人体的动物**开辟了前景。 2) 克隆实验的实施促进了遗传学的发展，
将受精卵克隆用于检测各种遗传疾病，克隆的3) 克隆技术也可用于检测胎儿的遗传**。
胚胎与子宫中发育的胎儿遗传特征完全相同。
4) 克隆技术可用于治疗神经系统的损伤。成年人的神经组织没有再生能力，但干细胞可以修复神经系统损伤。
5) 在体外受精手术中，医生常常需要将多个受精卵植入子宫，以从中筛选一个进入妊娠阶段。但许多女性只能提供一个卵子用于受精。通过克隆可以很好地解决这一问题。这个卵细胞可以克隆成为多个用于受精，从而大大提高妊娠成功率。
目前，克隆技术发展十分迅速。各国政府有关人士、民间对克隆技术的评价褒贬不一。克隆技术已展示出广阔的应用前景，包括以下四个方面：（1）培育优良畜种和生产实验动物；（2）生产转基因动物；（3）生产人胚胎干细胞用于细胞和组织替代疗法；（4）复制濒危的动物物种，保存和传播动物物种资源。在不久的将来，克隆技术技术将可以用来治疗糖尿病、中风、癌症、爱滋病、心脏病以及诸如帕金森综合症等精神疾病，并极大改变现有的**移植理论和治疗手段，给人类带来福音。然而，克隆技术也存在着一些弊端。在理论上，克隆技术还很不成熟；在实践中，克隆动物的成功率还很低，生出的部分个体表现出生理或免疫**，而且动物的残废率相当高并伴有早衰现象等。此外，克隆技术（尤其是人胚胎方面的应用）对伦理道德的冲击和公众对词的强烈反应也限制了克隆技术的应用。但几年来克隆技术的发展表明，世界各科技大国都不甘落后，谁也没有放弃克隆技术研究。我认为，克隆技术的巨大理论意义和实用价值在于它促使科学家们加快了研究的步伐，使克隆技术的研究与开发进入一个高潮，从而更好地为人类造福。
在医学上有好处，它也可以使许多没有生育能力的人完成梦想。
现在科学界把克隆分为治疗性克隆和生殖性克隆两种。前者是利用胚胎干细胞克隆人体**，供医学研究、解决**移植供体不足问题，这是国际科学界和伦理学界都支持的，但有一个前提，就是用于治疗性克隆的胚胎不能超出妊娠14天这一界限。而对于生殖性克隆，即通常所说的克隆人。
克隆是世界先进的技术，无可否认克隆能给我们带来好处。我们可以把一些聪明的人克隆一部分，让他们的聪明才智去造福人类。可以克隆自己，让“自己”先冷藏着，等到自己的身体零件出现问题时就拿“自己”的**放到自己身上，让自己延长寿命。也可以克隆人，让克隆人的**给一些有需要的人。其实我们不应该歧视克隆人，其实克隆人也是人，一定程度上来说，克隆人是比我们更纯洁的人。有人说克隆人的技术反展最终会给人类带来灭顶之灾，我觉得是错的，克隆人和我们一起生活，他自小与人类交往，有着人类的习惯和思想，也是和普通人没有分别的，因此，我们不应该歧视克隆人，就像我们不应该歧视艾滋病患者一样。
克隆很大程度上促进了人类科技文化的发展。克隆能为人类作出很大的贡献，它不但能有效地繁殖高附加值的牲畜，挽救珍稀动物，还对研究癌生物学，研究免疫学，研究人的寿命有不可低估的作用。但是，人类的欲望并不容易满足。从克隆动物的成功，人类自然而然地会想到克隆人。
它造福了人类。就克隆技术而言，“治疗性克隆”将会在生产移植**和攻克疾病等方面获得突破，给生物技术和医学技术带来革命性的变化。比如，当你的女儿需要骨髓移植而没有人能为她提供；当你不幸失去5岁的孩子而无法摆脱痛苦；当你想养育自己的孩子又无法生育??也许你就能够体会到克隆的巨大科学价值和现实意义。治疗性克隆的研究和完整克隆人的实验之间是相辅相成、互为促进的，治疗性克隆所指向的终点就是完整克隆人的出现，如果加以正确的利用，它们都可以而且应该为人类社会带来福音。
总的来说，克隆的优点包括：
一是利用克隆等生物技术，复制优良性状植株并加以改进，改变农作物的基因型，产生大量抗病、抗虫、抗盐碱等的新品种，从而大大提高农作物的产量。二是培育大量品种优良的家畜，如培养一些肉质好的牛、羊和猪等，也可以培养一些产奶量高，且富含人体所需营养元素的奶牛。三是对医疗保健工作产生重大影响，如依靠分子克隆技术，搞清致病基因，提出疾病产生的分子生物学机制；为**移植寻求更广泛的来源，将人的**组织和免疫系统的基因导入动物体内，长出所需要的人体**，可降低免疫排斥反应，提高移植成功率。四是为保护环境和濒危动植物，以克隆技术再现物种。五是为医学研究
提供更合适的动物，大大提高试验的精确度和安全性。
