作文二:《英语作文(克隆)》2200字
My views on cloning
Cloning technology, an asexual reproduction technology, is a great progress and breakthrough of human and technology, on which scientists have achieved remarkable results.
However, cloning is a mixed blessing. In a sense, it brings countless benefits to us. Firstly, by virtue of the technology, cloning change the genotype of crops, producing a large of number of disease resistance, inset resistance and other new varieties, which resulting in improving the production of crops greatly. Secondly, it can cultivate a mass of fine varieties of livestock to bring more ine to people, thus improving our living standard.Thirdly, therapeutic cloning provides more living chance to those who suffer serious disease difficult to cure so that their families and their themselves can get rid of the plight. Last but not least, it is conducive to clone the endangered animals and plants and protect the environment and species diversity.
There is no doubt that cloning have make great differences to mankind, in essence, it also has cons. On the one hand,from the perspective of social ethics, the
reproductive cloning is an intervene to natural development of human being, possibly disobeying the natural law. On the other hand, from the family’ s standpoint, what change the harmonious relationship among family members isthe collapse of the normal human moral order. What ’ s more, on the sexual ethics, the cloning will totally change the way of fertility which is based on the affection between each other, in some way causing the lack of love in the world. To be honest, what really get in the way of cloning is that the technology is not so mature by virtue of high stillbirth rates, fetal anomalies, death soon after birth, et cetera.
As far as I am concerned, I don not subscribe to cloning, especially reproductive cloning. A good many people attempt to do something against nature via cloning to serve their evil purpose, which will lead to inevitable chaos,threating our peaceful world. What I want to say is that” technology is a queer thing; it brings you great gifts with one hand,and it stabs you in the back with the other” .with many problems cloning brings in, I have no reason to send support to it and I will not e to tems with those who back the cloning.

克隆,与我们的生活息息相关,它的优点和缺点是什么,
关于这个主题的陈述你的观点。约150字。
The 21st century is a new era, the rapid development of science and technology. The development of scientific fields has caused a better life, but,technology is a double-edged sword and we should conservative use it. For example, Should we use the cloning technology?
To be or not to be, that is a question.
The Roslin institute is where Dolly the Sheep was born in1996 marking a breakthrough in the science of cloning. It means a new age dawned with the born of the Dolly andcloning technology has obtain the development at full speed over the next two decades. mankind have cloneda large number of animals, shch as horses, cows, pigs and so on. Of course, mankind have the ability to clone human itself, so it terrifying.
When asked whetherI support to clone, I am silent for a
1
while and giving the answer: We should use it reasonable.
Of course, some people think the answer is omnipotent to all questions, but it is useless. Actually this is not so, and as the ancient said: whatever is has every reason for being.Cloning technologyhas its advantages and
disadvantages.
Let me turn first to thedisadvantages of cloning technology. The focus of the problem maybe is human cloning, because of
the influence of moral and ethical that it has beenexists in humans for a very long time.Just think, if clone humanexists in our life, What kind of identity and social position does he should have?What happens if we don?t solve this? It is so horrible. What’s more, cloning technology can have
devastating consequences to nature, such as the unbalance ofecology, genovariation and so forth.
Next it?s time fortheadvantages of cloning technology. Cloning can saves endangered species from extinction and keep the ecological balance. What’s more, cloning
technology can produces human organ’s alternative for
some people which organ is diseased. Of course, cloning technology also has as a number of applications for every

aspect of human beings ?life.

作文四:《英语作文(克隆利弊)》1000字
Will cloning be promoted or prohibited?
With word that scientists succeeded in cloning an adult mammal being spread in air, it turns to a heated discussion that whether cloning will bring fortunes or misfortunes to human society.
Many believe that the advantages of cloning weigh over its disadvantages. They insist that cloning can save the rare wild lives from dying out. Also, cloning can throw light on some serious diseases. Maybe it can save people’ s lives.
While others argue that world with cloning is disastrous. They hold the view that cloning will destroy the ecological balance and an increasing number of transplants will be sold illegally. From their view of claim, cloning will make our world in chaos.
As for me, I stick to the opinion that every coin has two sides. That’ s to say, anything new-born will undoubtedly bring fortunes and misfortunes to the world. Therefore, it is we human beings that depend its trend. We should make full use of its fortunes and carefully avoid its misfortunes. In that way, I believe the future of cloning will be bright.

篇二:英语作文 对克隆的看法.doc
Cloning may be many things to many people.
Opinions are divided, some are in favor of it .The reasons are as follows. Primarily, people can produce effective drug, which patients can be treated with. Besides, the technology can save the endangered species. And best of all, it may give the disabled a healthy body.
Meanwhile, some people have contradicted opinions. Firstly, cloning human beings is a behavior which contradicts to the ethics. Besides, gene duplication may cause harm to the diversity of genes in nature.
From my angle of view, even though cloning techonology brings a lot of benefits, we cannot turn a blind eye to the negative influence which cloning brings about.
In sum, every coin has two sides. Cloning can do people good and harm, all depending on how to use it.
Cloning may be many things to many people. Some see it as a good technology. Because people can produce effective drugs to treat patients. While others view it as an evil
technology. Because gene duplication will cause harm to the
2
diversity of genes in nature. As far as Im concerned, cloning does bring a lot of benefits to human beings. Primarily, cloning could help farmers produce High quality and High-yield crops. Besides, the
technology could save the endangered species. And best of all, it may give the disabled a healthy body.
But all the above does not mean we can turn a blind eye to the negative influence which cloning brings about. Cloning human beings is a behavior which contradicts to the ethics. Also cloning does a great harm to the diversity of genes in nature.
In sum, cloning can do people good and harm, all depending on how to use it.
篇三:克隆——英语作文
For over a decade, the issue of clone has bee a flashpoint in the world, setting off waves of fierce debates whether clone should be directly prohibited in law making in many countries, as well as imposing strongly divergence in medical field. Over the past few years, the proponents have placed human organ cloning at the center of their agenda, steering money and muscle to persuade the law makers.
Proponents of clone argue all the time that it is a bliss for
3
human being to use cloning into organ transplantation. Whereas the opponents regard clone as a harmful challenge against the bottom line of moral. During the 59th United Nations General Assembly, Law Committee passed through a political declaration by the overwhelming majority, asking every country to forbid any form of human cloning which obeyed humanity. On the contrary, China held a definite attitude towards this question that China approved of using cloning in healing person. Though banned by the majority, this support gave the clone movement new momentum as well as let more people learn about therapeutic cloning.
The issue of clone came to the fore after the birthday of Sheep Dolly in 1996. Clone from then on became not only a reality but the same time a big problem confusing many countries for years as well. The debate on whether clone should be forbidden bees more and more controversial and hasn’t reached an agreement yet.

作文七:《大学英语作文克隆》3200字
We argue that human beings should not be cloned. Cloning of human beings is contrary to human dignity. Humans at large lose their uniqueness of
the individual. Cloned humans are regarded as a tool to benefit natural born humans, totally losing their fundamental rights as human beings. Cloning is a big threat to the basic ethic of human society.
Every single person on earth is unique and has theirspecial characteristics. But cloned humans are just copies of their creator. Obviously, that has destroyed any sense of humans’ individuality. The cloned humans would be
genetically induced to act a certain way.
Q: do you agree that Cloned humans are humans?
Cloned humans are humans, and as humans, they are naturally entitled fundamental human rights. Thus, their life, property, freedom and dignity are inalienable and inviolable. We have no rights to manipulate their destinies.
Why do humans want to clone themselves? Those who support cloning humans claim that human cloning benefits the majority of society.Cloned humans are created for the sole purpose of providing organ donations to naturally born humans,despite the fact that they are fully sentient and self-aware.
Technically speaking, we are killing cloned humans in order to save ourselves. When we accept this idea, we are, actually, admitting that killing is no longer definitely guilty and that we can kill humans with no punishment.
Although cloned humans are created by us, it is absolutely illogical to claim that it is justice to sacrifice a human’s life for another one. This idea violates morality and humanity, totally reflecting the selfishness of human nature. We are not the God, we should not create human beings, nor should we abandon their life so indifferently.
We also clone humans for couples who want to have a child, but cannot naturally.Yet, cloning might change the shape of family structure by plicating the role of parenting within a family of convoluted kinship relations. For example, a female DNA donor would be the clone's genetic twin, rather than mother, plicating the genetic and social relationships between mother and child, as well as the relationships between other family members and the clone. We could hardly figure out the exact roles of each other, it is a huge catastrophe for society.
And apparently, the cloned baby is not your child, is actually another yourself. The baby’s producing has no association with marriage, sex or
fertilization. It is a pure artificial product. So getting your own baby by cloning is just a wrong way. If you really want a child, you can fulfill your dream by adoption or raising test-tube baby.
Cloned individuals are often biologically damaged, due to the inherent unreliability of their origin; for example, researchers currently are unable to safely and reliably clone non-human primates. But they are going to create a lot of dead and dying babies along the way to clone a human being.
The cloned individuals act identically to the human they were cloned could greatly infringe on the right to self-determination. All humans should have the right to decide who and what they want to be to some extent. The cloned children may feel that they are expected to live a life that was predetermined.

I'm against human cloning
For cloning everyone is entitled to his own opinion, In my opinion I am against human cloning.
With the development of science and technology in the development of cloning technology, 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. But I think cloning will also bring a lot of the drawbacks. First of all, cloning unnatural, Natural all have their own rulesBut cloning break the law. Second May abuse cloning technology, For example some scientists want to human cloning, this will give the cloning of the people in life and some other aspects cause unnecessary trouble, 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? Finally,Also can cause ethical issues, and so on.
Therefore, I am against human cloning.What do you think?
作文十:《有关克隆的英语作文》8500字
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 (胚胎) carrying Missy,s DNA. None have survived the transfer to a
surrogate (代孕的) mother. The wastage of eggs and the many spontaneously aborted fetuses (胎) 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 mercial 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?
Cloning
Today’s technology develops so quickly that many impossible things bee 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 plete genetic material of a regular body cell. Different from the mon 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 thinks 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 diseases 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 mon 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.
Society
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 example, drug-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 2001, the first clone of an endangered wild animal
was born, a wild ox called a gaur. The young gaur died from an infection about 48 hours after its birth. In 2001, scientists in Italy reported the successful cloning of a healthy baby mouflon, an 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 antelope, the Sumatran tiger, and 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 bee a realistic option for the treatment of disorders

Firstly, I want to explain what is clone. In the dictionary, clone is a group of plants
or organisms produced asexually from one ancestor. It can replicate the gene from the best biology. So it brings us its usages. I think clone technology can help man to keep biology from being extinct. Even if there is an only existence of some species, we also can let this species goes on in the world. At the same time, man
can get a great much of benefit from it. If somebody lost his arm or leg, we can
replicate the new one by him gene. So there is no physical rejection. We will greatly help the disable to improve their life and reduce us cost in health-care.
As we all know that the 21st century is the science age,many magical scientific experiments are drawing our attention,while the cloning technology is the most popular topic.
The cloning refers to a means of raising up seed by bining the gender cell together.Although the cloning technology can breed new varieties,such as the people's organ,which can make a great contribution to humanbeings.However,the disaster brought by it is endless.
In fact,no matter how excellent the cloning technology is,failures can not be avoided,thus has alreasy been accepted among the researchers.As we can see,the cloning species are always of low survival rate like the sheep Dolly.In the 277 embryo fusion,only one survived,namely the success rate is only 0.36%.Besides,among large numbers of the cloning calves,most of them died for the heart anomaly or the uremia,and part of them have different degree of physiological defect and immunologic deficiency.However,at present,many scientists start the human beings' cloning.Many strange babies are born due to the failure of the cloning,which is disappointing to us.Thus is the clue of the human beings' cloning,undoubtedly,it seriously trample the lives.In addition,the human cloning really succeed,condusion must be brought to the law.The cloning people don't have the curators,which means that they are onlt the result of the scientists' research.The cloning people are exhaustive orphans,no one will take care of them.Therefore,it's cruel to the cloning people.
I believe that noone want to see thus happen,those crazy scientists destroy each cloning people's lives,undoubedly,it's a crime instead of a research.And noone will suppotr the research by killing the people.What's worse,thus research will bring more serious disasters and crime to humanbeings,which is also the improvement leading us going to the doom.
