Dolly the sheep became a scientific breakthrough when the news that she had been born was announced 1997.However,the problem that she later developed a serious lung disease bothered scientists.On 14th February 2003 scientists made the decision that Dolly should be put to sleep.Dolly's death,like her birth,was bound to raise worries.The fact that Dolly died when she was quite young disappointed people the world over.Scientists hold the belief that cloning may lead to many important scientific breakthroughs and medical treatments.But now the question comes to their minds,"Did she die young because she was a clone?" Besides that,there is also a fierce debate over the question whether human cloning experiments should be allowed.Scientists believe human cloning is just a matter of time but the assumption that human clones have already been born hasn't been proved yet.
当绵羊多利克隆出生的消息被发表的时候,她成为了科学上的一个突破.但是她不就就患上了肺部疾病,这成为了困扰科学家的一个问题.在2003年2月14日,科学家们做出了给多利实施安乐死的决定.多利的死,和她的出生一样一定会引发人们的担忧.事实上多利很小的时候就死了这让全世界的人都很失望.科学家们坚信克隆能带来许多重要的科学上的突破并且能用于医学治疗上.但是现在问题来了,“多利很小的时候就死了难道是因为她是克隆的吗?”此外,还有一个关于人类的克隆是否被允许的激烈的争论.科学家们相信人类的克隆试验仅仅是一个时间的早晚的问题,但是对于克隆人已经出生了的假设还没有被证明.
