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。
