克隆的利弊(The Advantages and Disadvantages of 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 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 d eath of Dolly,we are more conscious of the inefficient procedure of c lone.Acorrdi ng to "Dolly‘s false legacy",the incidence of death amo ng 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 br ing 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 d oner.But imagine,if you have a child owning the same apperance a s 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 th ese terrible aspects,the cloning of whole--being may destroy the diversity of people of the globe. Of course, there still remains much more disadv antages 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?

Its indisputable that cloning is a great process to produce quantities of commercial plants as well as new species of plants. However, the cloning of the sheep Dolly attracted publics attention but arouse a storm of objections.

However, every coin has two sides , the Internet also has its own advantages and disadvantages. On one hand, we benefit a lot from computers.

The internet also help us save a lot of time. The message was transfered so fast and so vivid that we don't have to walk out or have a face to face meet to resolve some business. We can also make friends by internet. On the other hand, the explosion messages were pushed to us whether you need it or not. So we have to spend a lot of time to figure out which one is a useful. We don't have to have a face to face talk most time, so we feel lonely and sometimes. More and more teenagers are addicted to virtual world and they all play computer games everyday they want, leading to a terrible result. The worst respect is that it grudually eat our health. We sit more and walk less, that caused backbone disease. The computer radiation affect our body, and so many disease are caused by it. Even though the usage of Internet has both positive and negative effect to me, I still consider Internet is a symbol of technology development. I believe I can use the Internet very well as long as I know how to control myself.

利弊类的英语作文(电子词典的利弊)
七、利弊类作文 Directions: For this part, you are allowed thirty minutes to write a composition on the topic Electronic dictionaries. You should write at least 120 words, and base your composition on the outline (given in Chinese) below: 1. 电子词典有很多好处 2. 电子词典也有许多弊端 3. 我的看法是…… Electronic Dictionaries I n recent years electronic dictionaries have become very popular as a study aid among students. Compared with a traditional dictionary, this kind of new dictionar y has many advantages. First, in comparison with a traditional dictionary, it’s obviously very handy and convenient Besides,due to its multifunction, it’s also very helpful. It cannot only translate words from English to Chinese, but vice versa. Some even can teach the learner how to pronounce a word. Most important of all, most of the entries in electronic dictionaries are comparatively updated. On the other hand, electronic dictionary has its disadvantages. First,the definitions in the entries are very limited.In addition, there are not enough explanations, patterns, or examples to illustrate the correct usage of word. Last but not the least, constant use of this study aid can make people too much attached to the dictionary and become lazy, which will lead them to form a passive and lazy attitude towards learning. In my opinion, we should use it properly and should have a good English dictionary at hand and treat the electronic one as a makeshift, when necessary.

关于“克隆”的英语辩论赛
关于“克隆”的英语辩论赛 关于“克隆”的英语辩论赛 (1) 中文资料 先看看人类对克隆技术的支持与反对人群: 支持者:狂人政客、恐怖分子、野心勃勃的科学家、渴望巨额利益的企业反对者:各国政府、国际组织、20余亿信仰上帝的教徒(上帝创造人类) 正方:1“克隆人”技术能使千千万万不孕症患者实现做父母的愿望;能使那些痛失骨肉的亲人重温天伦之乐;能为许许多多不治之症找到新的治疗方案;能创造巨大的物质财富和社会效益 2(克隆技术与遗传育种 在农业方面，人们利用“克隆”技术培育出大量具有抗旱、抗倒伏、抗病虫害的优质高产品种，大大提高了粮食产量。在这方面我国已迈入世界最先进的前列。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。 反方:1克隆技术还不完善。 ——克隆羊DOLLY就生病死了 ——克隆采用人工手段进行体细胞分离DNA然后再 次结合，有可能出现基因变异。 2违背人类伦理道德。重点(貌似是) ——克隆人没有传统意义上的父母。 ——克隆人没有家庭。 ——与某些宗教教义相抵触。 3还没有克隆人相关的法律 ——克隆人是否享有所有人类，公民的权利 ——有人可能利用克隆人作为廉价劳动力 ——某些组织，宗教可能利用克隆人进行活人祭祀 ——某些个人，团体可能利用克隆人犯罪。 ——克隆人是否属于其克隆行为的实施者，或者其 细胞提供者, 关于克隆人:1.会引起人类的大恐慌，因为有关可怕的克隆人的电影 早已把克隆人妖魔化了; 2.会引发道德伦理上的大讨论，因为奶奶的克隆体可能比孙子还小; 3.会引起另一种歧视，因为据说克隆人除非发生基因突变，或者被引入了其他基 因从而变成了转基因超人，不然是不会比人更强的。

Thought now there are lots of questions about cloning, by no means should we give in to the unsolved problems. 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。而人们对于这个问题的看法也各不相同，这完全可以理解。 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。

Advantages and Disadvantages of Internet As the internet developing with a growing pace, teenagers are a huge group which are most influenced. So here I’d like to mainly state some advantages and disadvantages of internet about this group. Since the internet is a symbol of this age, it must plays an important role in improving our lives. Internet gives some original ways of ideological education to teenagers. Educators could communicate with them as an internet buddy. Which can ease contradictions in time and have a effect of warming their heart. So it is more convenient for educators to doing their jobs better. Internet offers new channels for teenagers to obtain knowledge. In the situation where our country is short of resources of education, various online advanced courses meet with many students’ needs greatly. Internet broadens teenagers’horizon and improves teenagers’comprehensive qualities. Internet broadens their vision political field and category of knowledge, which forms their global awareness.
