  THE RETURN OF THE DINOSAURS?

  The possibility of cloning fierce and extinct① wild animals② has always excited film makers. And they are not the only ones! The popularity③ of films such as④ Jurassic Park⑤, in which a scientist clones several kinds of⑥ extinct dinosaurs, proves how the idea struck⑦ a mixture of fear and excitement into people's hearts⑧. But in fact we are a long way from being able to clone extinct animals. Scientists are still experimenting with⑨ cloning mammals. This is because⑩ the cloning of mammals is still a new science and its story only began seriously in the 1950s as this list shows⑪:

  1950s cloning of frogs

  1970s research using the embryos of mice⑫

  1979 work on embryos of sheep and mice

  1981 first experimental clones of mice

  1983 first experimental clones of cows

  1996 first clone of a mammal: Dolly the sheep⑬

  2000 cow gave birth to a bison⑭

  2001 China's first cloned twin calves⑮

  2002 first cloned cats

  2005 first cloned dog

  ...   ①extinct adj.灭绝的;消亡的

  ②介词短语of cloning ...作定语,修饰The possibility。

  ③popularity/ˌpɒpjʊ'lærətI/n.受人喜爱;流行

  ④such as 例如

  ⑤Jurassic/dʒʊə'ræsIk/Park 《侏罗纪公园》(美国电影名)

  ⑥several kinds of 几种

  ⑦strike/straIk/vt. & vi. (struck, struck)打;撞击;罢工n.罢工

  strike ... into one's heart使......刻骨铭心

  ⑧该句主干是The popularity of films proves how ...其中in which引导非限制性定语从句,修饰Jurassic Park。how引导宾语从句,作proves的宾语。

  ⑨experiment with 用......做实验

  ⑩This is because ... 这是因为......, because后接表原因的句子,在此是表语从句。

  ⑪as this list shows是as引导的方式状语从句。

  ⑫现在分词短语using the embryos of mice作定语,修饰research。

  ⑬Dolly the sheep 多莉羊

  ⑭bison/'baIsn/n.北美或欧洲野牛

  ⑮calf/kɑːf/n.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,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
