2017年6月英语四级写作练习：我对克隆的看法

　　参考范文：

　　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.

　　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 process to produce quantities of commercial plants as well as new species of plants.

　　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 genetic¹ diversity.

　　As for me,I suggest that cloning plays an important role on improving our quality of life.Needless to say,that cloning is an effective access to 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.

　　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。

　　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。

　　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。
