英语辩论赛——克隆

1、正方：自然界存在克隆现象…………Nature itself exists cloning phenomenon. In nature, there are many plants which are born with the instinct of cloning, such as potato, rose. Grafting is a clone. Besides, clone have already existed in natural animal and microbe. For example, monozygotic twins is actually a clone.反方：我认为你的观点有些偏离辩论赛的题目。

我们的辩论点是人类是否应该被克隆。

所以你应该应回到辩题上。

I think that your point have some deviation from the the subject of English debate contest. Our debate points is whether human cloning should be allowed. So you should be back to the subject.2、正方：是的。

…………比如器官移植。

T hank you for reminding me, but I cite these examples to illustrate clone has become an important technology. It can be used for the benefit of mankind, for example, used in organ transplantation反方：克隆技术依然不够成熟，它存在意想不到的结果。

在动物克隆试验中存在高失败率、高风险。

如多利羊寿命不长久。

It can cause some unexpective results because the cloning technology is still immature. Cloning experiments in animals that appear in the high failure rate, high-risk. Even the cloned animals may live a very short time. For example, Dolly lived only 6 years long, no more than half the average time.3、正方：…………不存在排斥现象。

英语ppt克隆

利用克隆技术可以在抢救珍奇濒危动物、扩大良种动物群体、提供足量试验动物、推进转基因动物研究、攻克遗传性疾病、研制高水平新药、生产可供人移植的内脏器官等研究中发挥作用
but if its application in human own reproduction, will have clone's a series of disputes. 但如果将其应用在人类自身的繁殖上，将产类器官移植的希望
美国先进细胞技术公司的研究人员称，他们利用成年牛耳朵上提取的体细胞，克隆出了类似肾脏的器官。该器官具备牛肾的部分功能，重新移植回牛体内后未发现有排异现象。让克隆人或克隆胚胎成为其母体的“备用零部件”，一旦其母体身上出现了器官移植等的需要，便可从他的克隆体上轻而易举地取得，而且这样取得的器官根本不存在移植后排斥的问题。如果将克隆胚胎培养成人，再从他身上取得某些“备用零部件”——器官作为移植之用，不过我们怎么能从一个人(因为克隆人也是人!)身上任意取得他的器官呢? 克隆人体器官是一条可行的解决途径，科学家想培育出一种可供器官移植的无头克隆人，使之成为人类器官的供应工厂，以解决目前移植器官紧缺的状况。不过，这一方法到底是否可行，还需有相应的国际社会可接受的基本原则相配套。
The twins were born at the same time ，they are natural clones
How many animals have been cloned?
Creating Dolly！ Dolly！
1997年2月22日，英国“Nature”刊登了爱丁堡罗斯林研究年月日英国“ 刊登了爱丁堡罗斯林研究所维尔穆特的研究成果，多莉”羊的克隆成功，所维尔穆特的研究成果，即“多莉”羊的克隆成功，从此震惊了世界。惊了世界。

克隆还是不克隆英语作文总结

克隆还是不克隆英语作文总结Cloning or Not Cloning: A Comprehensive ExplorationThe debate surrounding the ethics and implications of human cloning has been a topic of intense discussion and controversy in recent years. As advancements in biotechnology continue to push the boundaries of what is possible, the question of whether we should embrace or reject the practice of cloning has become increasingly complex and multifaceted. In this essay, we will delve into the various perspectives on this issue and strive to arrive at a well-informed conclusion.One of the primary arguments in favor of human cloning is the potential to address the pressing issue of organ shortages. Cloning technology could enable the creation of genetically-matched organs, reducing the risk of rejection and providing a viable solution for those in need of life-saving transplants. This prospect has been met with cautious optimism by some in the medical community, as it holds the promise of saving countless lives and improving the quality of life for those suffering from organ failure.Additionally, proponents of cloning argue that it could offer a meansfor individuals to have genetically-related children in situations where traditional reproductive methods are not feasible or desirable. For example, same-sex couples or individuals with fertility issues could potentially utilize cloning technology to have a child that shares their genetic makeup. This could be viewed as an expansion of reproductive rights and a way to fulfill the deeply personal desire to have a biological child.Furthermore, some advocates of cloning believe that the technology could be employed to preserve the genetic legacies of individuals who have passed away, allowing their loved ones to create a clone and continue their lineage. This concept, while controversial, speaks to the human desire to maintain a connection with those we have lost and to ensure that our genetic imprint endures beyond our own lifetimes.However, the opposition to human cloning is equally compelling and deserves careful consideration. One of the primary concerns is the potential for the misuse of cloning technology, leading to the exploitation of vulnerable individuals or the creation of a "designer baby" market. There are fears that cloning could exacerbate existing social inequalities, with only the wealthy and privileged having access to this technology, further widening the gap between the haves and the have-nots.Additionally, the safety and long-term implications of cloning are not yet fully understood. The process of creating a cloned human being is complex and fraught with potential risks, including genetic abnormalities, developmental issues, and unknown psychological and social consequences. The ethical and moral implications of bringing a genetically-identical individual into the world are also deeply troubling to many, as it raises questions about the nature of identity, individuality, and the sanctity of human life.Another significant concern is the potential impact of cloning on the traditional family structure and societal norms. The introduction of cloning technology could disrupt established notions of parenthood, kinship, and the role of genetics in shaping our identities. This could lead to complex legal and social challenges, as well as the potential for the exploitation of vulnerable individuals, such as children born through cloning.Moreover, the religious and philosophical objections to human cloning cannot be overlooked. Many faith traditions and belief systems view the creation of life as a sacred and divine act, and the idea of humans playing God through cloning is seen as a violation of this natural order. Additionally, some philosophers argue that cloning undermines the fundamental principles of human dignity, autonomy, and the inherent worth of each individual.In conclusion, the debate surrounding human cloning is a complex and multifaceted issue that defies simple answers. While the potential benefits of cloning, such as addressing organ shortages and expanding reproductive options, are compelling, the ethical, social, and safety concerns cannot be ignored. As a society, we must carefully weigh the risks and rewards, engage in robust public discourse, and strive to develop a comprehensive regulatory framework that balances the advancement of science with the protection of human rights and dignity. Ultimately, the decision to embrace or reject human cloning will have far-reaching implications for the future of humanity, and it is a responsibility that we must approach with the utmost care and consideration.。
