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
