克隆英文辩论
DEBATEHuman cloningSHARK PK NOTHING CONTANT:引入者：（正方一辩）Did you ever imagine having a child that is the exact replica of you? Did you ever imagine of having the cure for heart disease or cancer? Well, these fantasies are not far from reach. The way we could reach these fantasies is through a process called cloning. Cloning is the replication of an exact genetic copy of an organism by use of a somatic tissue (or cell) from the donor organism. Cloning can be used in humans, human organs, or even animals. There are many advantages and disadvantages of cloning.引入者：（反方一辩）One disadvantage is whether if cloning is ethical. Cloning will bring up a great controversy on whether if cloning is the “right” thing to do or not. This controversy is currently going on right now and will be even a greater controversy if the government allows cloning. Many people think that nature should just take its course.正方二辩：A benefit of cloning is cloning human organs or body parts. If a person has a dysfunctional liver or heartthen they could get it cloned and get a brand new one. These are some of the benefits of cloning.反方二辩：Another disadvantage of cloning is that it has not been perfect yet. The cloning of the sheep Dolly had 276 failures before successfully cloning a sheep. With these kinds of figures we should not even go near trying to demonstrate cloning on humans.Someone is going to do it, legal or illegal. But it seems only logical to do it under strict government supervision with the best trained professionals rather than letting some maniacal(癫狂的） scientists do it and let his clone run loose.Now cloning is banned in the United States. The government is not supporting the experiment of cloning through any means.正方三辩：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.反方三辩：Huxley illustrates the future with people having One more disadvantage of cloning can be studied through the works of Aldous Huxley in his book the “Brave New World.”“total loss of individuality, creativity, and freedom. ” This is because if humans are then there would be a lot of the same people in the future. An example would be if a person is cloned and was cloned 3 times. This would cause trouble because none of theseclones will have anything unique about themselves. The future of cloning is very questionable.正方四辩：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.反方四辩：In conclusion,To reduce the risk of having more disadvantages of Cloning, human cloning should not be prohibited simply because it does not insure immediate benefits, but it should be experimented with for potential future use.And cloning is a study in biotechnology that has unlimited possibilities. There are disadvantages such as not perfecting the technique of cloning. Despite this fact, cloning will be an ongoing process and will be tested. Hopefully,cloning will not be a downfall to human history but rather a step closer to a better society.正方一辩：Cloning is the replication of an exact genetic copy of an organism by use of a somatic tissue (or cell) from the donor organism. Cloning can be used in humans, human organs, or even animals. A benefit of cloning is cloning human organs or body parts. If a person has a dysfunctional liver or heart then they could get it cloned and get a brand new one. It is favorable for human’s development.反方一辩：I think that your points 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.正方一辩：Thank you for reminding me, but I cite these examples to illustrate clone has become an important technology today.It can be used for the benefit of mankind, for example, used in organ transplantation.反方一辩：It can cause some unexpective results because the cloning technology is still immature（不成熟的）. Cloning experiments in animals that appear in the high failure rate and high risk.正方二辩：However，I think the cloning technology for organ transplantation has many benefits. It can seek more extensive sources for organ transplantation, reduce the immunological rejection and improve the success rate of transplantation. For example, cloning technology can be used for the treatment of nervous system damage. Adults can’t regenerate nerve cells. but stem cells can repair the nervous system injury.反方二辩：Although what you say is an actual fact,Some people may use the clone technology to clone human and harvest for organs transplanting. Then what we human are? I think it is a violation of human rights. Furthermore, most religious people are on the down-side of cloning. So Many people say that cloning is messing with the naturalorder of things.正方二辩：I want to say that a single organ cloning isn’t a violation of human rights. In addition, Cloning technology can also be used to multiply valuable genes. For example, in medicine realm, insulin is produced to treat diabetes. Through genetic selection, we can control the genetic disease.反方二辩：There are some problems .Firstly, the cloning technology is difficult, very difficult to reach a certain number, even if there are so few clones will come into the world, it may be a threat(威胁） to human survival.正方三辩：But the acceptance of things that people have a process, the human moral concepts can be changed. Recently, a father wrote that his 5-year-old son died of leukemia(白血病）,the father grieved,and eager to rapid progress in cloning the country, became the first beneficiary. Requires clone of his dead child can not say that sub-human nature, right?正方三辩：The law does not prevent the development of technology, but it provides guidance and limitations, which gain sufficient time to prepare and psychological, institutional preparation, in order to fully and estimated the negative effects of technological development, while avoiding disadvantages, the establishment of a set operation systems and rules, aslong as the Government to strengthen management, cloning can minimize the harm.反方三辩：You said that cloning is beneficial to curing diseases. But now the technique of it is not proven and it is under the base of contributing human beings' organs. If we continue to research in it deeply,maybe we will waste precious contributed organs and hunt donators. Meanwhile, how can we assure its safety?The answer is not transparent now.正方四辩：Again, the development of technology has its own internal rules, the cell technology is unstoppable. In life science research, cloning is a very useful technique. Even if people disagree on the cloning of people do not say categorically do not need to engage in human society, human cloning. Human cloning research will address some theoretical issues in developmental biology provide an opportunity, but also may provide useful technique to humans. Do not always think about the ethics of human cloning, legal and moral, which easily tied the hands of scientists and creativity. cloning technology itself will be in play and social development in the future of its great potential. As long as it is conducive to improving the quality of human survival and sustainable development of cloning technology as a standard of value, can make them better for the cloning of human and social services.From what have been said above, our team strikes that human cloning is not good.反方四辩：Hello, everyone,next, I will summarize,cloning is not good.First, opening proposition illustrated a lot of advantages of cloning. It is true. But for most of people,we can say that cloning is useless and even that it can't link to our daily lives. And then,you also said that cloning is good for agriculture. Maybe it can come true someday. But now we have organic plants and relatively serious management of agriculture. Why we still challenge and take a risk? It's not really realistic. Improving production of organic plants can solve the problems too.Obviously, it's much practical. On balance, actually cloning is beneficial to some areas, but it is not practical to popularize and spread.If cloning is spread, it is likely to raise panic and troubles.It is controversial. And it is against moral appeals and conscience. It's possible that lawbreakers especially terrorists make use of cloning to do something bad for human beings for the world.If diving in cloning, it should be under strict government supervision with the best trained professionals rather than letting some scientists do it and let his clone run loose.Considering the severe consequences,we emphasize that the disadvantages of cloning outweigh the advantages.From what have been said above, our team strikes that human cloning is not good.Thank you for your listening.。

发表对克隆看法的英语演讲稿范文Title: The Ethical Dilemma of Cloning: Opportunities and Challenges.Ladies and Gentlemen,。
Today, we delve into a topic that has generated intense debate and争议 within the scientific, ethical, and social circles: cloning. As we embark on this journey, let's maintain an open mind, examining the potential benefits, ethical challenges, and the wider societal implications of this remarkable technological feat.Cloning, in essence, is the process of creating an identical copy of a biological entity, whether it's a gene, a cell, or an entire organism. The scientific advancements in this field have been nothing short of revolutionary, offering new hopes and perspectives in medicine, agriculture, and even conservation efforts.Medically, cloning holds the promise of revolutionizing transplantation medicine. Imagine a world where organs for transplantation can be grown in a lab, eliminating the need for donors and the associated risks of rejection. This could potentially save millions of lives, especially those with chronic organ failure. Furthermore, cloning could pave the way for personalized medicine, where treatments are tailored specifically to an individual's genetic make-up.In agriculture, cloning offers the potential for more efficient and sustainable food production. Crop cloning could lead to higher yields, resistance to diseases and environmental stress, and a reduction in the use of pesticides and herbicides. This, in turn, could contribute to global food security and environmental sustainability.However, these potential benefits must be carefully balanced against the ethical challenges and societal implications of cloning. One of the most significantethical concerns is the violation of the uniqueness and dignity of human life. Cloning raises questions about the value of human life and the sanctity of the individual. Ifwe can create identical copies of ourselves, what does that mean for our identity, our uniqueness, and our place in the universe?Moreover, cloning raises concerns about the potential misuse of technology. Could cloning be used for nefarious purposes, such as creating a race of slaves or soldiers? Could it lead to a eugenics movement, where certain traits or abilities are cloned to create a "superior" race? These are serious questions that we must grapple with as a society.Additionally, cloning raises questions about the role of natural reproduction in human society. Reproduction is a natural process that is integral to human life and culture. If cloning becomes widely practiced, what would the implications be for family structures, social dynamics, and the very fabric of society?Finally, we must consider the impact of cloning on the environment. While cloning in agriculture could potentially lead to more sustainable food production, it could alsolead to genetic homogenization, reducing the resilience and diversity of our food systems. This could have devastating consequences for our environment and ecosystems.Ladies and Gentlemen, cloning is a remarkable technological feat that offers巨大的 potential benefitsbut also poses significant ethical and societal challenges. As we continue to explore the frontiers of science and technology, it is crucial that we approach these issues with a balanced perspective, considering both the opportunities and the risks.We must strive to create a world where technology serves humanity, rather than the other way around. This requires a concerted effort from all of us, scientists, policymakers, and the general public alike. Only through open dialogue, critical thinking, and responsible action can we ensure that cloning remains a force for positive change in our world.Thank you for your attention.。
关于克隆的讨论英语作文
关于克隆的讨论英语作文In today's world, the concept of cloning has generated immense debate and controversy. Cloning, a scientific process that involves creating an exact genetic copy of an organism, has the potential to revolutionize medicine, agriculture, and even our understanding of life itself. However, this remarkable technology also raises numerous ethical, moral, and social concerns. In this essay, we will explore the pros and cons of cloning and analyze its potential impact on our society.One of the most significant benefits of cloning is its potential to revolutionize medicine. Cloning could lead to the development of personalized medicine, where patients could receive treatments tailored to their specific genetic makeup. For example, stem cells derived from cloned embryos could be used to treat a wide range of diseases, including diabetes, Parkinson's disease, and heart disease. Additionally, cloning could provide a source of organs for transplantation, potentially saving the lives of thousands of people who are currently waiting for organ donations.Moreover, cloning could also have significant agricultural benefits. By cloning genetically superior plants or animals, farmers could produce higher yields and reduce the need for pesticides and antibiotics. This could lead to more sustainable and environmentally friendly agricultural practices.However, despite these potential benefits, cloning also raises numerous ethical and moral concerns. One of the most significant concerns is the cloning of humans. The creation of human clones could lead to a slippery slope, where people are cloned for unethical purposes, such as assisted reproduction or as a source of organs for transplantation. This raises questions about the sanctity of life and the moral status of cloned individuals.Another concern is the potential for cloning to lead to genetic monocultures. If all plants or animals are cloned from a single, genetically identical source, it could lead to a lack of genetic diversity, making our food supply and ecosystems more vulnerable to diseases and pests. This could have disastrous consequences for our planet's biodiversity and ecological stability.Furthermore, cloning raises serious social and psychological concerns. For example, the cloning of humans could lead to a divide between cloned individuals and their "original" counterparts, potentially creating a new form of discrimination based on genetics. Additionally, the cloning process itself could have negative psychological effects on individuals involved, such as feelings of loneliness, isolation, and a lack of personal identity.In conclusion, cloning is a remarkable technology that has the potential to revolutionize medicine, agriculture, and our understanding of life itself. However, it also raises numerous ethical, moral, and social concerns that must be carefully considered. As we move forward with this technology, it is crucial that we strike a balance between harnessing its potential benefits and protecting the rights and well-being of all individuals involved.**克隆技术：一把双刃剑**在当今世界，克隆的概念引发了巨大的争议和讨论。
克隆的好处 英文作文
克隆的好处英文作文英文：Cloning has been a controversial topic for decades,with both its benefits and drawbacks being debated. In my opinion, cloning has many advantages that cannot be ignored.Firstly, cloning can help to preserve endangered species. With the increasing rate of extinction, cloningcan be used to create new individuals and increase the population of endangered species. For example, in 2003, scientists successfully cloned a gaur, an endangeredspecies of wild cattle, which was the first time a wild animal was cloned.Secondly, cloning can be used to produce genetically identical animals for research purposes. This allows scientists to study the effects of certain drugs ordiseases on a specific genetic makeup without the variables of different genetic backgrounds. For example, cloning hasbeen used to create mice with specific genetic mutationsfor studying diseases like cancer and diabetes.Lastly, cloning can also be used in the medical fieldto produce organs for transplant. With a shortage of organ donors, cloning can provide a solution by creating organs that are genetically identical to the recipient, reducing the risk of rejection.In conclusion, cloning has many potential benefits that cannot be ignored. While there are also ethical concerns surrounding cloning, the advantages it offers cannot be dismissed.中文：克隆技术是一个长期备受争议的话题，其优缺点一直在被辩论。

High schools are no exception, as students engage in lively discussions on the ethics, morality, and potential consequences of cloning. This debate is not just about science; it's about exploring the fine line between human progress and ethical boundaries.**The Pros of Cloning**Many students argue that cloning has the potential to revolutionize medicine and science. Cloning human cells and organs could lead to groundbreaking treatments for diseases like diabetes, Parkinson's, and heart disease. Imagine being able to create a perfect match for a transplant without the need for immunosuppressive drugs or the risk of rejection. This could save thousands of lives and improve the quality of life for millions.Moreover, cloning could be a powerful tool in conservation efforts. Endangered species could be saved from extinction by cloning their genes and reproducing them in controlled environments. This could help maintain biodiversity and preserve the natural world for future generations.**The Cons of Cloning**However, others argue that cloning raises serious ethical and moral concerns. Cloning humans, for instance, could lead to a slippery slope where we start manipulating human genetics for non-therapeutic reasons, such as enhancing athletic ability or intellectual capacity. This could lead to a divide between "haves" and "have-nots" in society, where only the wealthy can afford to clone themselves or their children.Furthermore, cloning could have unintended consequences on society. If cloning becomes widespread, it could lead to a decrease in genetic diversity, making humanity more vulnerable to diseases and other threats. Additionally, the psychological impact of cloning on individuals and families needs to be carefully considered. Would cloned individualsbe treated as equals in society? Would they have the same rights and opportunities as their "original" counterparts? **The Way Forward**In conclusion, the debate on cloning is complex and multifaceted, involving ethical, moral, and scientific considerations. While cloning has the potential to bring remarkable benefits to medicine and conservation, it also raises concerns that need to be carefully addressed. As a society, we must strike a balance between harnessing the power of science and preserving our ethical values.As high school students, we have a responsibility to engage in this debate and form our own opinions.

辩论 克隆
辩论主题：我看克隆正方：支持克隆（克隆利大于弊）反方：反对克隆（克隆弊大于利）基本材料：1、克隆的含义：生物体通过体细胞进行无性繁殖，复制出遗传性状完全相同的生命物质或生命体。
——在线《辞海》克隆是英文"clone"或"cloning"的音译，而英文"clone"则起源于希腊文"Klone"，原意是指以幼苗或嫩枝插条，以无性繁殖或营养繁殖的方式培育植物，如扦插和嫁接。
在大陆译为“无性繁殖”在台湾与港澳一般意译为复制或转殖或群殖。
中文也有更加确切的词表达克隆，“无性繁殖”、“无性系化”以及“纯系化”。
克隆是指生物体通过体细胞进行的无性繁殖，以及由无性繁殖形成的基因型完全相同的后代个体组成的种群。
通常是利用生物技术由无性生殖产生与原个体有完全相同基因组织后代的过程。
——百度百科克隆（英语：Clone）在广义上是指利用生物技术由无性生殖产生与原个体有完全相同基因组之后代的过程。
在园艺学上，克隆是指通过营养生殖产生的单一植株的后代，很多植物都是通过克隆这样的无性生殖方式从单一植株获得大量的子代个体。
在生物学上，是指选择性地复制出一段DNA序列（分子克隆）、细胞（细胞克隆）或是个体（个体克隆）。
克隆一个生物体意味着创造一个与原先的生物体具有完全一样的遗传信息的新生物体。
目前，现代生物学背景下，这通常包括了体细胞核移植。
在体细胞核移植中，卵母细胞核被除去，取而代之的是从被克隆生物体细胞中取出的细胞核，通常卵母细胞和它移入的细胞核均应来自同一物种。
由于，细胞核几乎含有生命的全部遗传信息，宿主卵母细胞将发育成为在遗传上与核供体相同的生物体。
粒线体DNA这里虽然没有被移植，但相对来讲粒线体DNA还是很少的，通常可以忽略其对生物体的影响——维基百科2、克隆的应用及例子（历史上的克隆动物）：蛙：1962年，未成功鲤鱼：1963年，中国科学家童第周将一只雄性鲤鱼DNA插入来自雌性鲤鱼的卵成功克隆了一只雌性鲤鱼，比多利羊的克隆早了33年。
克隆利弊的英语作文
克隆利弊的英语作文克隆是一项先进技术，有着利与弊，把克隆的利与弊以英语作文的方式写出来应该如何写呢？下面是店铺为大家分享的是克隆利弊的英语作文的范文，希望对你有帮助!篇一：克隆的好处与坏处(1286字)Increased food security for growing populationsIf 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 needsto be done before therapeutic cloning can become a realistic option for the treatment of disorders.篇二：克隆技术利弊(1050字)With the development of science and technology, our side appeared a lot of new things,such as clone,The scientific invention of clone has become a hot topic among people,especially among the young and heated debates are right on their way. Now the cloning scientific has been used for many years to produce plants, it has brought us a lot of benefits but has created some serious problems as well. The benefit of cloning is cloning human organs or body parts , such as that if a parson in a traffic accident lost his arm or leg ,or someone get a serious heart disease and face danger ,he need a new body parts replace ,At this time we can use cloning technology copy a new parts of body to replace ,in the this way can be ensure that someone continue to live ,so that the clone is benefit for us . Everything has two sides and cloning is not an exception,it has both advantages and disadvantages. On the contrary,most people are against of cloning technology been used in our life, One of the biggest reason is that human cloning technology will break the gender balance,it will be bring up a great chaos. As far as I think cloning technology is more much disadvantage for human being ,we should very careful to use it, I believe that only in this way our life will be more beautiful篇三：克隆的好处与坏处(1920字)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 reproduc--tion 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 diversity of people of the globe.Of course, there still remains much more disadvantages ofthe 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 ourselvesSo how do u think about it?。

关于克隆的讨论英语作文
关于克隆的讨论英语作文The Ethics and Possibilities of Cloning.Cloning, a biotechnology that has captivated theworld's attention, presents a range of fascinating possibilities and controversial ethical challenges. At its core, cloning involves the creation of a genetically identical copy of an organism, whether it be a bacterium, plant, or animal. While the concept of cloning has existedin science fiction for decades, its real-world applications and implications are still being widely debated.One of the earliest and most famous examples of cloning was the creation of Dolly the sheep in 1996. This groundbreaking experiment, led by Ian Wilmut and his teamat the Roslin Institute in Edinburgh, Scotland, marked the first time that a mammal had been cloned from an adult cell. Dolly's birth sparked a global discussion about the ethics and potential uses of cloning technology.On the one hand, cloning offers the promise of remarkable medical advancements. For instance, it could potentially revolutionize the field of regenerative medicine by providing a limitless supply of cells and tissues for transplantation. This could be especially beneficial for patients with degenerative diseases or injuries that require tissue replacement. Cloning could also be used to create "biofactories" that produce valuable biopharmaceuticals, such as insulin or other hormones, in a controlled and efficient manner.Moreover, cloning could be employed in conservation efforts for endangered species. By cloning individuals from genetically diverse populations, scientists could potentially reintroduce them into the wild, helping to restore population levels and genetic diversity. This approach could be particularly useful for species that are difficult to breed in captivity or for which there are few remaining individuals.However, the potential benefits of cloning must be weighed against its ethical implications. One of the mostsignificant concerns is the cloning of human beings. While many argue that human cloning could be used to treat infertility or to create tissue for transplantation, others fear that it could lead to the commodification of humanlife and the creation of a new class of genetically engineered "designer babies." Such scenarios raise profound questions about the sanctity of life, human dignity, and the role of genetics in defining our identity.Another ethical concern is the potential for cloning to perpetuate genetic diseases and disabilities. If a cloned individual inherits the same genetic defects as their original, they may be subject to the same health problems and shortened lifespan. This raises questions about the morality of creating a being that is genetically predisposed to suffering.Additionally, the cloning process itself is not without risks. Dolly the sheep, for instance, died prematurely due to complications related to her cloning process. This suggests that while the technology has made significant progress, it is not yet perfect, and there may beunforeseen health consequences for cloned individuals.In conclusion, cloning is a complex and controversial topic that raises a wide range of ethical and scientific questions. While it offers the promise of remarkable medical advancements and conservation efforts, it also presents significant ethical challenges that must be carefully considered. As we continue to explore the possibilities and limitations of cloning technology, it is crucial that we approach this topic with a balanced perspective, considering both its potential benefits andits potential costs. Only through careful consideration and responsible stewardship can we ensure that cloning technology is used ethically and responsibly to benefit society.。

3(克隆技术与濒危生物保护克隆技术对保护物种特别是珍稀、濒危物种来讲是一个福音，具有很大的应用前景。
从生物学的角度看，这也是克隆技术最有价值的地方之一。
4(克隆技术与医学重点:病人的福音在当代，医生几乎能在所有人类器官和组织上施行移植手术。
但就科学技术而言，器官移植中的排斥反应仍是最为头痛的事。
排斥反应的原因是组织不配型导致相容性差。
如果把“克隆人”的器官提供给“原版人”，作器官移植之用，则绝对没有排斥反应之虑，因为二者基因相配，组织也相配。
问题是，利用“克隆人”作为器官供体合不合乎人道,是否合法,经济是否合算,克隆技术还可用来大量繁殖有价值的基因，例如，在医学方面，人们正是通过“克隆”技术生产出治疗糖尿病的胰岛素、使侏儒症患者重新长高的生长激素和能抗多种病毒感染的干挠素，等等。
