1、cloning: where is it leading us?克隆一直在我们左右并且已经被大多数人接受。它是一种用来准确复制其他动物或者植物的方法。在植物方面，克隆就发生在园丁从正在生长的植物上切去切口用来制造新的植株的时候。在动物方面也有克隆现象，比如说两个拥有同样性别以及外貌的同卵双胞胎。这两个事实都是自然界里的克隆例子。cloning has always been with us and is here to stay. it is a way of making an exactexact copy of another animal or plant. it happens in

5、生产具有商业价值的植物。其次，它对于新的植物物种以及动物医药方面的研究极具价值性。植物克隆相对于动物克隆来说简单得多，而动物克隆则比较困难。it is a difficult task to undertake. many attempts to clone mammals failed. but at last the determination and patience of the scientists paid off in 1996 with a breakthrough - the cloning of dolly the sheep. the procedure works li

10、，这是它的原型羊寿命的一半。可悲的是，同样无法控制的命运也在影响着其他物种，如克隆鼠。科学家的脑海里产生的问题是：“这是不是所有的克隆动物的一个主要困难呢？”这种现象会不会永远发生？如果改进程序。问题会不会解决？on the other hand, dollys appearance raised a storm of objections and had a great impact on the media and public imagination. it became controversial. it suddenly opened everybodys eyes to the p
