克隆技术利弊英语作文

　　Nowadays, the controversial issue of cloning has been in the limelight and has aroused wide concern in the public. It’s quite understandable that the views of this issue vary from person to person. 如今，关于颇受争议的克隆问题已经明确地引起了大众广泛关注，克隆技术利弊英语作文。而人们对于这个问题的看法也各不相同，这完全可以理解。 Some people are in favour of cloning, who firmly believe that scientists can bring the extinct animals back to life by cloning. It’s indisputable that cloning is a great proceto produce quantities of commercial plants as well as new species of plants. 有些人很支持克隆，他们坚定地相信科学家们可以通过克隆技术将灭绝的动物重现天日。而且无需置疑的是克隆技术能帮助大量生产经济作物和新品种。 However, the cloning of the sheep Dolly attracted public’s attention but arouse a storm of objections. For instance, if heaps and heaps of evil leaders like Hillary attempt to clone themselves, a disaster will break out in the world. In addition, the objectors insist that cloning has a huge impact on genetic diversity. 然而，多利羊的克隆吸引了大众的注意，同时也引起了一阵强烈的反对。例如，一大群邪-恶的领导人试图克隆他们自己，世界就要爆发大灾难了。此外，反对者还认为克隆会对基因的.多样性产生很大的影响。 As for me, I suggest that cloning plays an important role on improving our quality of life. Needleto say, that cloning is an effective acceto cure serious illnesses that at present have no cure. What’s more, not only can cloning assist us to acquire unknown knowledge about the creature, but it also is a wonderful breakthrough. Thought now there are lots of questions about cloning, by no means should we give in to the unsolved problems. 至于我，我认为克隆对提高我们的生活质量还是有很重要作用的。更不用说，克隆不仅可以帮助我们了解许多关于生物的未知问题，而且它还是一项很好的突破。尽管现在克隆上还有着许多难题，但是绝不意味着我们就要为这些难题而让步。

　　I to enumerate pros and cons,let everybody comment?Leon:1) cloning technology can relieve those who cannot become the mother of women suffering.2) cloning experiments to promote the implementation of the genetics of development,for "create" can the animal organs transplanted opened up a prospect.3) cloning technology also can be used to test fetal genetic defects.Will be fertilized,used to detect various genetic disease cloned embryos and uterus,cloning and genetic characteristics of fetus develops in exactly the same.4) cloning technology used for treatment of the nervous system damage.Adult nervous tissue regeneration,but no stem cells can repair neurological damage.5) to in vitro fertilization surgery,doctors often need to connect multiple fertilized implanted in the womb,with a into pregnancy stages from screening.But many women can only provide an egg for fertilisation.Through cloning can well solve the problem.The eggs can clone into multiple for fertilization,which greatly improve pregnancy rate.Disadvantages:1) cloning would reduce the genetic variation,through cloning produces the individual has the same genetic,the same diseases sensitivity,a disease could destroy the generated by cloning of groups.Can imagine,if one country herds will have the same cloning product,a lesevere virus could destroy the national husbandry.2) cloning technology use will make people tend to multiply the existing population of the most value of the individual,rather than by natural laws to promote the whole population of the muck.In this sense,the cloning technology to interfere with the natural evolution process.3) cloning technology is an expensive technology,need a lot of money and biological professional participation,failure rate is very high.Dolly is 277 experiments only results.Although now developed more advanced technology,the succerate was only to reach 2-3%.4) transgenic animals raised the risk of infection.For example,if a drug milk cow production infected with virus,which may be through milk infection patients 5) cloning technology applied to the human body will lead to the offspring of artificial control genetic traits.Cloning technology debate whether to allow the core is the development of early human embryos for genetic operation.This is many ethicists not acceptable.6) cloning technology can also be used to create "superman," or have strong physique but mental retardation.Moreover,if cloning technology can effectively use among humans,men also lost genetic significance.7) cloning technology to the effects of family relationships will also is huge.A father's DNA cloning generated children can as father's twin brother,only delayed decades was born just.It is hard to imagine that,when a person find yourself is simply another person's completely reproductions,he (or she) what it feels like to be?Say so,science and technology is sometimes a double-edged sword,advantages and disadvantages,and don't have no standard answer!Just watching people such use!
