高三英语作文素材:克隆或者不克隆,这是个问题
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 Dollys 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 dont 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 lets 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 husbands, will you accept it without any uncomfort?
Dont 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.Dont 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?
