染雾克隆英语作文 篇一：克隆技术的应用和争议
克隆技术是一种将生物体的基因复制并制造出相同的个体的科学技术。自从克隆羊多莉成功诞生以来，克隆技术就引起了广泛的争议和讨论。克隆技术的应用涉及医学、农业、生物研究等领域，但同时也引发了伦理、道德以及法律等方面的争议。
在医学领域，克隆技术被广泛应用于生殖医学和再生医学。在生殖医学中，克隆技术可以帮助不育夫妇实现生育梦想，通过克隆技术可以复制出健康的个体，并将其植入母体内发育成胚胎。在再生医学中，克隆技术可以用于治疗各种疾病，例如利用克隆技术制造出器官和组织，用于替代患者受损的组织。这些应用无疑为医学领域带来了巨大的突破和进展。
然而，克隆技术也引发了一系列的争议和担忧。首先，克隆技术的应用可能导致道德和伦理问题。例如，克隆人类是否符合道德和伦理原则，是否存在人类尊严和自由意志等问题。其次，克隆技术的安全性和可行性也是人们关注的焦点。由于克隆技术仍处于发展初期，其潜在风险和未知因素可能导致克隆个体的健康问题，如克隆个体可能存在先天缺陷或其他生理问题。此外，克隆技术的滥用可能导致人类种群的多样性减少，从而对生物多样性和生态系统产生不可逆的影响。
为了解决克隆技术的争议和问题，各国纷纷制定了相应的法律和伦理准则。一些国家禁止人类克隆，但允许克隆动物；而另一些国家则完全禁止克隆技术的应用。此外，国际社会也在积极开展克隆技术的研究和监管，以确保克隆技术的合法和安全应用。
综上所述，克隆技术的应用和争议是一个复杂的问题。虽然克隆技术在医学和科学研究领域具有巨大的潜力和前景，但其伦理、道德以及法律等方面的争议也不能忽视。我们需要在克隆技术的应用中权衡各种利弊，确保其安全可行，并加强监管和法律体系的建设，以促进克隆技术的可持续发展。
克隆英语作文 篇二：克隆技术对社会的影响与挑战
克隆技术是一项具有革命性的科技，它可以复制出与原生物体基因相同的个体。随着克隆技术的不断发展，它在社会中产生了深远的影响和挑战。
首先，克隆技术对农业和食品安全产生了重要影响。通过克隆技术，我们可以复制出高产、抗病虫害的农作物和畜禽。这将提高农业产量和食品供应，有助于解决全球粮食短缺问题。然而，克隆食品也引发了食品安全问题。一些人担心克隆食品可能对人体健康产生潜在风险，因此对克隆食品的监管和标识成为了一个亟待解决的问题。
其次，克隆技术对医学领域带来了巨大的突破和进展。通过克隆技术，我们可以复制出健康的胚胎和组织，用于治疗各种疾病。克隆技术也有望解决器官移植的瓶颈问题，提供更多的器官供给。然而，克隆技术的应用也引发了一系列的伦理和道德问题。例如，是否允许克隆人类，以及克隆人类是否具有与自然产生的个体相同的权利和地位等问题。
此外，克隆技术对社会的道德观念和价值观念产生了冲击。克隆技术的出现使得传统的生殖观念和家庭观念发生了变革。例如，克隆技术使得“亲子关系”这一概念变得模糊，人们对于亲子关系的定义和认同也发生了改变。这对社会的家庭结构和人际关系产生了深远的影响。
综上所述，克隆技术在农业、医学和社会等领域产生了重要的影响和挑战。我们需要正视克隆技术所带来的问题和争议，并加强监管和伦理道德的建设，以确保克隆技术的安全合理应用，促进社会的可持续发展。
克隆英语作文 篇三
Westhusin’s experience with cloning animals leaves him upset by all this talk of human cloning. In three years of work on the Missy project, using hundreds upon hundreds of dog’s eggs, the A&M team has produced only a dozen or so embryos carrying Missy’s DNA. None have survived the transfer to a surrogate mother. The wastage of eggs and the many spontaneously aborted fetuses may be acceptable when you’re dealing with cats or bulls, he argues, but not with humans. "Cloning is incredibly inefficient, and also dangerous," he says.
Even so, dog cloning is a commercial opportunity, with a nice research payoff. Ever since Dolly the sheep was cloned in 1997, Westhusin’s phone has been ringing with people calling in hopes of duplicating their cats and dogs, cattle and horses. "A lot of people want to clone pets, especially if the price is right," says Westhusin. Cost is no obstacle for Missy’s mysterious billionaire owner; he’s put up $3.7 million so far to fund A&M’s research.
Contrary to some media reports, Missy is not dead. The owner wants a twin to carry on Missy’s fine qualities after she does die. The prototype is, by all accounts, athletic, good-natured and supersmart. Missy’s master does not expect an exact copy of her. He knows her clone may not have her temperament. In a statement of purpose, Missy’s owner and the A&M team say they are "both looking forward to studying the ways that her clones differ from Missy."
Besides cloning a great dog, the project may contribute insight into the old question of nature vs. nurture. It could also lead to the cloning of special rescue dogs and many endangered animals.
However, Westhusin is cautious about his work. He knows that even if he gets a dog pregnant, the offspring, should they survive, will face the problems shown at birth by other cloned animals: abnormalities like immature lungs and heart and weight problems~ "Why would you ever want to clone humans," Westhusin asks, "when we’re not even close to getting it worked out in animals yet?
克隆英语作文 篇四
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.

To clone or not to clone, is that the question?
Advanced technology has already pushed human being to edges,such as the production of weapons of mass destruction,the destruction of Ozone by Freon ,and the application of clone.The heated deabte over whether cloning technique should be used in human reproduction must be considered as a serious issue.
Clone, to a certain degree, is beneficial to mankind.Such disease as Parkinsons will possiblly be cured in the future in the hope of further applying of clone.However,the abuse of this technology will bring human being unthinkable destruction.
Since the declaration of the death of Dolly,we are more conscious of the inefficient procedure of clone.Acorrding to "Dolly's false legacy",the incidence of death among fetuses and offspring produced by cloning is much higher than it is through natural reproduction--roughly 10 times as high as normal before birth and 3 times as high after birth.And even you may argue that this technology will be perfected in the future, i don't see there is any point in whole--being cloning.
Many people consider this technology a promising one as to bring all human being to a new era in which all human reproduction will be accomplished by cloning.Thus scientists in some countries have already started their great plan to clone human.But let's think, what is the practical value in doing so?You may tell me that it can bring hope for those couples unable to have children because they might choose to have a copy of one of them rather than accept the gene intrusion from a doner.But imagine,if you have a child owning the same apperance as yours or your husband's, will you accept it without any uncomfort?
Don't you think it is embarrassing?Or if this kind of human reproduction is allowed,terrorists may get hold of it and reproduce lots of "American Presidents".Don't you agree that these presidents might bring the world much more chaoes?Besides these terrible aspects,the cloning of whole--being may destroy the persity of people of the globe.
Of course, there still remains much more disadvantages of the application of cloning reproduction of human being and animals. We should be extremely cautious of what we do and thus remember we will sure be respondible for all the results created by ourselves!!!
So how do u think about it?
克隆英语作文 篇六
You can read the word "cloning" quite often in the newspaper. I find it very interesting. It seems like a fairy story.With cloning you will be copied. Today, scientists can clone some large animals. Doctors are in the process of cloning humans though it is not allowed in most of the countries.
Cloning brings a lot of questions. If someone can come to the world with only one parent, will he or she be happy? My grandmother died a few years ago. I miss her very much. If she can be cloned into a new one, I'll be very happy but confused.What shall I call her after she comes into the world? Because"she -- my grandmother" is younger than I.
