精选作文:克隆利弊谈(450字)作文
克隆既能造福于人类，又可能冲击人们的传统观念，它就像是一把双刃剑。
克隆可以造福人类——克隆可以有效地繁殖具有“高附加值的牲畜”。克隆可以用来挽救“濒临绝种”的动物。克隆对于人类疾病的防治，寿命的延长具有重要意义。
克隆的却有很多益处。正如《奇妙的克隆》一文中所说，“用自己的细胞克隆成一个胚胎”，将其进行培养，可以“替换自己病变的机关”，解除人的病痛。
不仅如此，克隆技术还可用于即将灭绝的动物，使他们能够继续延传下去而不会导致灭绝，影响整个生物圈。
虽然克隆的好处很多，但任何事物都有两面性，科隆既然有益处，那么它也会有相应的弊端。
克隆也会给人类带来灾难。比如说“克隆人”，世界人口众多，“克隆人”的产生会使地球人口增长率达到极点，地球将会出现危机。“克隆人”也可能对社会经济和道德伦理以及法律法规造成危害。
人们应严肃的考虑克隆的技术应用，是克隆技术尽可能地造福于人类。

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 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 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?

10—7班 王素英
上网，可以查资料，关注世界各大新闻（事件），是学习最好的老师；上网可以听歌，看书，是放松心情的小护士；上网可以淘宝，不出门就能买到自己心爱的衣服，佩件，项链，手机等等，是生活的大超市，上网能开阔视野，不出门便知天下事。
上网聊天对于学生来说有百害而无一利，尤其是网恋，它会使你纯洁的思想受到污染，影响学习，变得堕落；上网玩儿游戏有时是在放松心情，但是需要你坚强的意志力，如果玩儿到痴迷的程度，在网上乱杀人，觉得杀人特别容易，已经不是一个正常的人，甚至会做出对社会不利的事件。
上网影响人们的身体健康。科学家说人们的睡眠时间：晚上11点到白天4点，每天要保证7小时的睡眠时间。有些学生晚上不睡觉，跑出去上网，通宵，一夜不睡觉，眼睛疲劳，衰退，流泪，影响身体健康，造成各种疾病。
上网对帮助了我们，同时又加害我们的思想，关键要看一个人的意志力，平时的习惯。如果合理上网，它会帮助你登上顶峰，获得成功，如果最终攻破你的心理防线，你会堕落到最深的大海海底，永远上不来，毁掉你的前途。

上网，可以查资料，关注世界各大新闻，是学习的最好的老师；上网可以听歌，看书，是放松心情的小护士；上网可以淘宝，不出门，就能买到自己心爱的衣服，佩件，项链，手机等，是生活的大超市，上网能开阔视野，不出门便知天下事。
上网聊天对于学生来说有百害而无一利，上网影响人们的身体健康。科学家说人们的睡眠的黄金时间是晚上11点到凌晨4点，并且要保证7小时的睡眠时间。有些学生晚上不睡觉，跑出去上网，通宵，眼睛疲劳，视力衰退，影响身体健康，造成各种疾病。上网聊天还好，如果发生网恋，它会使你纯洁的思想受到污染，影响学习，变得堕落；上网玩儿游戏有时是在放松心情，但是需要你坚强的意志力，如果玩儿到痴迷的程度，在网上乱杀人，觉得杀人特别容易，就已经不是一个正常的人，甚至会做出对社会不利的事情。
由此看来，上网对我们既有利又有害，到底是利是害，关键要看一个人的意志力，如果合理上网，它会帮助你获得成功，如果不合理，他最终会攻破你的心理防线，使你堕落到最深的海底，永远也上不来，毁掉你的前途。
我们应该合理利用电脑，对自己有利的积极学习，不利的尽量避免，使自己成为一个有用的人才，为国家贡献出自己的一份才智。
