Dolly the sheep多莉羊? bis on/bals n/n.北美或欧洲野牛? calf/k an.小牛；牛犊恐龙的回归？第1段译文克隆凶猛和灭绝的野生动物的可能性一直使电影制片商感到兴奋。然而他们并不是唯一对此感到兴奋的人！在侏罗纪公园这部影片中，有一位科学家克隆了好几种不同的绝种恐龙。 类似这样的电影很受欢迎，证明了这一想法使人们感到既兴奋又恐惧。但事实上，要想克隆 绝种动物，我们还有很长的路要走。科学家们现在还在进行克隆哺乳动物实验。这是因为克 隆哺乳动物仍然还是一门新的科学，它是从20世纪50年代才开始认真进行研究的

7、，如下列所示：20世纪50年代：克隆青蛙20世纪70年代：用老鼠胚胎进行研究1979年：对羊和老鼠的胚胎进行研究1981年：首次对老鼠进行实验性的克隆1983年：首次对奶牛进行实验性的克隆1996年：首次克隆哺乳动物（多莉羊）2000年：奶牛生野牛2001年：中国首次克隆出双胞胎小牛2002年：首次克隆猫2005年：首次克隆狗From time to time people suggest? from time to time (相当于sometimes, notthat ext inct ani mals like dino saurs, canvery often)不时；偶尔3needed

8、 for them to lead a naturallife33.第2段译文不时地会有人提议， 克隆技术将有可能使地球上已经灭绝的动物（如恐龙）复活。不幸的是，据我们现在所知这是不可能的，也是不合适的。其原因有很多：?首先要求你有完好的DNA它提供有关细胞将如何生长的信息）。possibly be brought back to life throughbring back to life使复生；使复活cloning.Unfortunately,with what we know?now, this is either impossible or?The in itialn eedperfe

There are many reasons.4?如果某个动物群体没有足够的多样性以战胜疾病，那么克隆这种动物的所

13、有努力都将5是无用的。种群多样性是指种群中动物的基因以不同的方式排列。其优点是，如果发生了某种新的疾病，这类动物中的一些可能会死去，而另外一些却能存活下来， 并且把这种免疫力传给下一代。经过克隆的动物群体的最大缺点是：它们的基因排列有可能完全相同， 因而它们有可能会死于同一种疾病。这样它们可能一个也留不下来传宗接代了。?你如果克隆出任何绝种动物，而它们必须生活在动物园里，那是不公平的。它们需要适当的栖息地过正常的野生生活。第3段译文就我们现在所知道的而言，不可能克隆那些已经绝种了一万年以上的动物。事实上恐龙在6 500万年以前就已经消失了。所以说恐龙回归地球的可能性仅仅是个梦想罢了。Step
