篇1：有关克隆英语作文
Increased food security for growing populations
If the low success rates can be improved (Dolly was only one success out of 276 tries)reproductive cloning can be used to develop efficient ways to reliably reproduce animals with special qualities.For exampledrug-producing animals or animals that have been genetically altered to serve as models for studying human disease could be mass-produced.
Reproductive cloning also could be used to repopulate endangered animals or animals that are difficult to breed.In 2001the first clone of an endangered wild animal was borna wild ox called a gaur.The young gaur died from an infection about 48 hours after its birth.In 2001scientists in Italy reported the successful cloning of a healthy baby mouflonan endangered wild sheep.The cloned mouflon is living at a wildlife center in Sardinia.Other endangered species that are potential candidates for cloning include the African bongo antelopethe Sumatran tigerand the giant panda.Cloning extinct animals presents a much greater challenge to scientists because the egg and the surrogate needed to create the cloned embryo would be of a species different from the clone.
Therapeutic cloning technology may some day be used in humans to produce whole organs from single cells or to produce healthy cells that can replace damaged cells in degenerative diseases such as Alzheimer's or Parkinson's.Much work still needs to be done before therapeutic cloning can become a realistic option for the treatment of disorders.
增加粮食安全的人口增长
如果低成功率可以提高(新子只有一个成功了276次)，生殖性克隆可以用来开发可靠地重现动物特殊的素质的有效途径。例如，药品生产的动物或动物已经转基因作为研究人类疾病模型可以大量生产。
生殖性克隆也可以用来填充濒危动物或动物是很难繁殖。2001、濒危野生动物的第一个克隆人的诞生，野牛称为野牛。年轻的野牛死后出生48小时感染。2001，意大利的科学家们报道了一个健康的宝宝摩弗伦羊的克隆成功，濒临灭绝的野羊，克隆摩弗伦羊是生活在撒丁岛的一个野生动物中心。其他濒危物种，克隆的潜在候选人包括非洲邦戈羚羊，苏门答腊虎，和大熊猫。克隆灭绝的动物提供了一个更大的挑战，科学家因为鸡蛋需要创造克隆胚胎将一种不同的代理从克隆的租金。
治疗性克隆技术可能有一天被用于人类从单细胞或产生健康的细胞，可以替代退行性疾病如阿尔茨海默氏症或帕金森的多数作品受损细胞之前仍然需要治疗性克隆可以成为治疗病症的一种现实选择产生整个器官。

With the development of our science and technology cloning becomes more and more close to our lives. Looking at another you probably could be a fun however some people think that it will bring a lot of trouble such as how to identity which one is real. In my opinion we do not need to clone a whole body of you. For example when you lose one of your fingers they can just clone a new finger for you. And that would a very good application in medical use. Thus I think that we should use the clone to make our life better off.
随着我国科学技术的发展，克隆技术越来越接近我们的生活。看着另一个你可能会是一个有趣的，但是，一些人认为，它会带来很多麻烦，如如何身份，这是一个真正的。在我看来，我们不需要克隆你的整个身体。例如，当你失去了你的一个手指，他们可以为你克隆一个新的手指。这将是一个很好的应用在医疗使用。因此，我认为我们应该使用克隆，以使我们的生活变得更好。
篇3：有关克隆英语作文
Today’s technology develops so quickly that many impossible things become true; the cloning technology is the example. What is cloning? Cloning is a process used to create an exact copy of a mammal by using the complete genetic material of a regular body cell. Different from the common propagate cloning need only one cell and without sex. In 1997 the great news shocked the whole world that the British scientists created a lamp named Dolly from a single cell miraculously; the cell had been taken from the udder of adult sheep which show the first cloning experiment was successful.
When the cloning technology improves so quickly many scientists and doctors have different opinions someone think it is good but someone think it is bad. 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.
But cloning still has some problems. The scientists found that the cloning animal’s Gene has a little different from the original animal. So the life will shorter than the real life. The fact proved that the cloning sheep Dolly has died. It only has the half life of the common sheep.
In my own opinion I agree to clone the endangered animal and disagree with cloning human. Because I think the cloning technology should be respected. It really can bring us many benefits; further more it can develop the science of human. If clone the human there will however be many problems the population is the biggest problem. May be some people will use the cloning people to start the war. So I am against cloning human.
Also many countries disagree to clone people. The government makes the laws about cloning. There are laws against human cloning in Canada Denmark England Norway Spain and the UK. Even in the USA the government doesn’t allow to clone human. (Because in USA the human right is higher than everything)
In the end I think cloning is new technology it should be accepted how to look upon this technique first we should know the advantages and disadvantages then we should know the effect of cloning for human and the animal third we will take the action: To advocate the animal cloning but be against with the human cloning.
今天的技术发展得如此之快，以至于许多不可能的事情都变成了事实，克隆技术就是这样的例子。什么是克隆?克隆是一个通过使用正常的身体细胞的完整的遗传物质来创造哺乳动物的精确副本的一个过程。不同于普通的繁殖，克隆只需要一个细胞，而不需要性。1997、好消息震惊，英国科学家发明了一种灯从一个单细胞，命名为新子世界奇迹;细胞已经被成年羊的乳腺，这表明第一个克隆实验成功了。
当克隆技术提高得如此之快，许多科学家和医生有不同的意见，有人认为这是好的，但有人认为这是坏的。克隆可以给人类带来许多好处，如恢复，有助于有缺陷的基因，肝功能衰竭，肾功能衰竭和白血病。这些疾病是非常不同的治愈，如果我们使用克隆技术，我们可以改变基因的DNA顺序，所以我们可以节省很多人。
但克隆仍然存在一些问题。科学家们发现，克隆动物的基因与原来的动物有一点不同。这样的生活会比现实生活短。事实证明，克隆羊新子已经死了。它只有普通绵羊的半衰期。
在我看来，我同意克隆濒危动物，不同意克隆人类。因为我认为克隆技术应该受到尊重。它确实可以给我们带来许多好处，它可以进一步发展人类的科学。如果克隆人，会有很多问题，人口是最大的问题。可能有些人会用克隆人发动战争。所以我反对克隆人类。
也有许多国家不同意克隆人。政府制定有关克隆的法律。在加拿大、丹麦、英国、挪威、西班牙和英国都有针对克隆人的法律。即使在美国，政府也不允许克隆人类。(因为在美国，人权高于一切)
最后，我认为克隆是新技术，它应该被接受，如何看待这个技术，首先我们应该知道的优点和缺点，那么我们应该知道人类和动物克隆的影响，第三我们将采取行动：倡导动物克隆但是反对与人类克隆
