A variety of explanations have been (4) by psychologists for this "childhood amnesia". One argues that the hippo-campus; the region of the brain which is (5) for forming memories, does not mature until about the age of two. But the most popular theory (6) that, since adults don’t think like children, they cannot (7) childhood memories. Adults think in words, and their life memories are like stories or (8) one event follows (9) as in a novel or film.

①目前，有关基因的两条新闻不期而遇地撞到一起。
②一则令人高兴，六国科学家联合宣布，继去年成功绘制人类基因组工作框架之后，他们又绘制出了更加准确、清晰、完整的人类基因组图谱，对人类基因的面貌有了新的发现。
③另一则令人悲伤，美国北圣菲铁路公司被美国公平就业机会委员会告上法庭，要求该公司停止对雇员进行基因缺陷检测。这是美国首例与工作场所、基因陷私和基因歧视有关的法律纠纷案。
④诚如人们时下习惯于用“双刃剑”来描述全球目前所面临的诸多问题一样，基因技术发展，同样也未逃出科学进步与传统道德相互冲突的困局，而上述两则新闻，正是这一困局的最具有代表性的体现。
⑤毫无疑问，人类基因图谱的精确绘制，具有里程碑式的历史性意义。如果说19世纪的科学家用无素周期表描述世界，为20世纪的科学革命铺平道路，那么现在的基因解码一定会在21世纪掀起生物和医药领域里的革命。
⑥科学家们已在着手确定每个基因及其功能，而以往的治病方式也可能将因之而改变。人类将能以罹患各种疾病的可能性来衡量人体的健康，毋须等到真正患病。
⑦正因为如此，有人担心，今后可能会发生因基因异常而歧视某人的现象。道德家们则更忧虑依据基因而判定一个人的性格和成败。所以，有科学家呼吁，有必要教育医生和公众：让他们知道基因知识有哪些极限。毕竟，人不只是一堆基因那样简单，换句话说，人类绝非各种基因加起来的产物。基因固然重要，但更重要的基因之间的关系，以及基因与人体其他物质之间的相互联系。
⑧尽管人类已破解了基因图谱，但现在距离认识基因彼此之间的关系仍很遥远。人体内有10万亿个细胞，每个细胞里数万个基因，它们彼此间发生怎样的作用，产生怎样的结果，人类恐怕永远也都不会知道。
Does using a word processor affect a writer s style
The medium usually does do something to the message after all, even if Marshall McLuhan’ s claim that the medium simply is the message has been heard and largely forgotten now. The question matters. Ray Hammond, in his excellent guide The Writer and the Word Processor, predicts that over half the professional writers in Britain and the USA will be using word processors by the end of 1985. The best known recruit is Leu Deighton, from as long ago as 1968, though most users have only started since the microcomputer boom began in 1980.
Ironically word processing is in some ways psychologically more like writing in rough than typing, since it restores fluidity and provisionality to the text. The typist’ s dread of having to get out the Tippex, the scissors and paste, or of redoing the whole thing if he has any substantial second thoughts, can make him consistently choose the safer option in his sent
