国家教育部颁发的《大学英语教学大纲》对大学英语的后续课程——专业英语提出了明确的要求。《大纲》将专业英语规定为继大学英语四级之后的一门正式课程。大学英语四、六级阶段的教学主要侧重于传授语言基础知识与培养基本的语言技能，而能否使学生的语言知识转化成较强的专业应用能力，则在很大程度上取决于英语后继课程的教学是否成功。因此，提高学生的英语应用能力，已成为各高等院校共同面对的课题。 然而，在从普通英语向专业英语的过渡阶段，当前高校学生尤其是理工科大学生仍缺乏一套可以反映近年来世界科学信息的系统教材，我们特此编写《21世纪科技英语》，旨在提供一种通用性强、便于理工科各专业使用的教材。 本书的选材以近年来发表的英文科普文章为主，有些直接由因特网上下载。我们注重趣味性、信息性、可思性和前瞻性，同时也注重语言的规范性和文体的多样性。语言富有科技英语的语言特色，含有丰富的通用与专业科技英语词汇和科技英语语法结构。语言地道、措辞简洁，难度略高于大学英语四级水平。内容广泛，涉及领域既包括了理、工、医、农等常用的基础类学科，又紧扣当前科技最新的技术成果和未来的科研方向，如生命科学、数字电路、基因工程、纳米技术等。使用对象为理工科高年级学生或广大科研人员。 全书共分上、下册，共有20个单元。每单元分Text A和Text B。Text A为精读，文章后面配有练习。我们编写时尽量使其形式新颖、实用，有利于达到提高专业英语应用能力之目的。Text B为泛读，每篇文章均有详细注解，有助于同学们课外自习。此外，本书还摘录了一些有关科技工作者如何书写科技论文、口头进行科技报告的技巧与方法以及科技英语方面文体风格的短文，语言风趣、幽默。相信研修本教程的学员定有耳目一新的感觉。 在本教材编写过程中，周海英、刘剑、雷亮华、计颖等老师在材料的搜集及文字打印等方面做了不少工作，在此一并致谢！ 由于时间紧迫，加之我们水平有限，书中错误在所难免，敬请读者不吝赐教。

Does adding more people tothe planet make society any worseoff？ Lately economists have tended to reject gloom-and-doom scenar-ios of impending environmental catastrophe, concluding that popula-tion growth only slightly perturbs living standards. At the meetlng,however, two economists unveiled a new analysis suggesting thatmore people do impose a cost on society——one that could run thou-sands of dollars a head. If the analysis holds up in this hotly debatedarea of economics, the result could be "extremely important," sayspopulation biologist Jeol Cohen of Rockefeller University in New YorkCity. "It makes clear the interest of the present generation in slowingpopulation growth." Economists William Nordhaus and Joseph Boyer of Yale Univer-sity took a fresh look at the old question of how population growthmight affect a countrys economic well-being. They used global datafor 13 regions on gross domestic product （GDP）, capital, and popu-lation from the 1960s to the 1990s to project the costs to society ofeach additional person, years into the future. The team went a stepfurther than other economists ,have by estimating, for the first time,the economic costs of a slightly warmer planet as each persons ac-tivities spew out more-greenhouse gases~. Also unlike previousmodels, the researchers analyzed .how parental decisions affect theeconomic well-being of not just the current generation but future gen-erations, through the 22nd century.
