玻璃——捕捉光晕的舞步

威廉·埃利斯

长期以来，玻璃以其各种形式高尚地为人类服务。作为使用最为广泛、性能最多样化的人工制造材料，玻璃既可以用来制作如网球场般大的望远镜的镜面，也可以制作又小又简单在地上滚动的弹珠。新技术进一步拓展了这种极具可塑性的材料的用途。长度超过800万英里的玻璃光纤把电话和电视信号传递到五湖四海，玻璃陶瓷可以用来制作导弹的鼻锥体和牙齿的人造冠，玻璃微珠可以对人体的特定器官进行靶向放射治疗，甚至还可以为了清除核废料而把它加工成一种新型的玻璃。

光学计算机即将问世，其工作原理是通过光子（即小型激光发射的脉冲）而不是通过电子来储存程序、处理信息。脉冲通过玻璃纤维而不是通过铜丝传递。光学计算机的运行速度将比如今的电子计算机提高几百倍，储存的信息量也大大增加。如今，由于纤维光学技术的运用，我们能够观察到的物体越来越细微，甚至细菌病毒的内部结构也能一览无遗，所看到的图像也越来越清晰。新一代的光学仪器已经出现，可以详尽地呈现细胞内部的运动。正是纤维光学和液晶显示技术的大量运用，已经拥有15万名员工、总产值达160亿美元的美国玻璃工业不得不新建工厂增加产量以满足市场的需求。

然而，玻璃不仅在技术和商业领域拓宽了用途，起源于古罗马时代的传统—玻璃艺术也繁荣起来。几乎到处可见人们在吹制玻璃工艺品。“1975年之前我没有卖掉过一件玻璃制品，”戴尔·奇休利

微笑着说。然而，经历了低潮期之后，18年前玻璃艺术再现辉煌，如今奇休利成了20世纪最为成功的商业艺术家之一。现在，他又接到了一宗新的活儿，为一家比萨饼公司的总部制作一个玻璃雕塑，这个任务将为他带来50万美元的酬劳。

然而，并不是所有与我们生活相关的玻璃技术都是超现代的。以简单的灯泡为例，在本世纪初，大多数灯泡都是人工吹出来的，一个灯泡的成本相当于一个普通工人半天的报酬。事实上，20世纪20年代康宁公司发明的带式玻璃成型机照亮了全美国，使得灯泡的价格大幅下降。毫无疑问，这项成就被称为人类历史上最伟大的机械发明之一。然而，其工作原理却非常简单：将玻璃熔化成狭窄的液体带状，令它在一根上面有孔的移动的钢条上行进，玻璃液通过小孔流入准备好的模具中，喷出压缩的空气接着把玻璃定型。用这种方式，一台机器一小时可以制作66000个灯泡外壳，而4个吹玻璃工人一天的产量仅为1200个。

玻璃性能多样化的奥秘在于其内部结构。尽管玻璃像固体一样是刚性的，其原子的分布却像液体一样是随意混乱的。在熔化的过程中，原材料中的原子在其分子结构中的正常位置被打乱，而在原子还原到晶体结构的分布之前玻璃就冷却了。这种分子结构的松散性使玻璃具备了如工程师所说的极强的“可塑性”，因此技术人员可以根据需要任意裁剪玻璃。

如今，科学家正继续试验新的玻璃混合材料，建筑设计师则通过使用特殊玻璃继续发挥他们的想象力。伦敦建筑师迈克·戴维斯

甚至设想了用分子化学技术设计奇妙的大楼。他说：“玻璃是未来重要的建筑材料，是建筑物的动态皮肤。想象一下可以与通过的电流起反应的玻璃，通过按钮控制在透明与不透明之间切换的玻璃，这就形成了瞬时窗帘。想象一下只需不断变换玻璃的颜色，纽约的高楼大厦就可以上演一出颜色的交响乐。”由玻璃制作的瞬时窗帘已经研制成功了，只是价格不菲。至于变色玻璃，也有可能成为现实。迈克·戴维斯的设想或许即将成真。

21世纪大学英语第一册课文的翻译 Unit1 TextA 优等生的奥秘 埃德温·基斯特莎莉·瓦伦丁·基斯特 现在是剑桥大学理科一年级学生的阿历克斯，曾在曼彻斯特的中学校队里踢足球，还导演过学校的戏剧演出——但他中学毕业时得了五个A。在布里斯托尔大学攻读英语的阿曼达在中学里参加过戏剧演出，还经常打网球，但她仍然得到了四个A。 像他们这样的优等生是如何做到这一点的呢？脑子好使并不是唯一的答案。最有天赋的学生未必在考试中取得最好的成绩。懂得如何充分利用自己的才能要重要得多。 学习刻苦也不能说明全部问题。在这些成绩优秀的学生中，有些人投入的时间其实比那些分数低的同学还少。班级中拔尖学生的成功之道在于他们掌握了一些基本的技巧，这些技巧其他人也能很容易地学到。根据教育专家和学生们自己的叙述，优等生成功的奥秘有以下几点。 1.全神贯注！拔尖生不允许他们的学习时间受到干扰。一旦书本打开，便电话不接，电视不看，报纸不读。“这并不意味着对生活中的重要事情置之不理，”阿曼达解释说，“这意味着要安排好学习时间，以便能全神贯注。要是我牵挂一位患病的朋友，我会在做功课之前先给她打个电话。这样我坐下来学习时，就能真正集中心思了。” 2.在任何地方——或所有的地方学习。亚利桑那州一位教授曾奉命辅导一些成绩欠佳的大学运动员。他记得有一名赛跑运动员每天都要训练。他曾说服他利用这段时间记忆生物学术语。另一名学生则把词汇表贴在盥洗室墙上，每天刷牙时都记住一个生词。 3.安排好资料。汤姆在中学时打过篮球。“我非常忙，不可能为了找一支铅笔或一本不见的笔记本而浪费时间。我把每样东西都放在随后可取的地方，”他说。新墨西哥州学生保罗为每门功课备有两个文件夹，一个放当天布置的作业，另一个放已完成要交的家庭作业。一个抽屉把必需的用品放在一起，这样就可减少因找东西而浪费的时间。 4.安排好时间。当教师布置写一篇长论文时，阿历克斯会花两三天时间去阅读与题目有关的资料并做笔记，然后写出草稿，再写成论文。他会计划好在作业该交的前两三天完成，以便如果花费的时间超过预期，他还能在规定的最后期限前完成。阿曼达严格遵守一张学习时间表，其中包括每两小时休息一次。“在你过度疲劳时还试图学习并不明智，”她指出，“短暂的休息，哪怕只是伸展一下身体，呼吸呼吸新鲜空气，也能带来意想不到的效果。” 5.学会阅读。“我过去常花许多时间阅读一些无关的资料，”阿曼达回忆说，“但后来我习惯了快读；如果一段文章的第一句话无关紧要，我便接着读下一段。”“我修过的最好的一门课便是快速阅读，”一名俄克拉荷马州的学生说，“我不仅提高了每分钟阅读的词数，而且学会了首先看书的目录和插图。这样，当我开始阅读时，我就对阅读材料先有了一些了解，而且能记住更多的内容。”在这些学生看来，有效阅读的奥秘就在于做一个主动的阅读者，即能不断提出一些能使自己充分理解所读材料的问题。 6.做好笔记。“在写任何东西之前，我先把一页纸分成两部分，”阿曼达说，“左边部分约占纸宽的三分之一；右边部分占三分之二。我把笔记写在宽的一边，而把中心思想写在左边。这在复习时非常有用，因为你马上就能看到为什么这些材料是有关的，而不用为信息量太大而发愁。”在下课铃响起之前，多数学生便已经合上书本，收好作业，和朋友们说说话儿，准备离开了。而聪明的学生却利用这几分钟，用两三句话写出这堂课的要点，下一次上课之前，他便可以把这些要点浏览一遍。 7.问问题。“如果你问问题，你立刻就会知道，你是否已经掌握了要点，”阿历克斯说。课堂参与是一种求知欲的显示。例如，在经济学课上，好奇的学生会问，中国经济怎么可能既是社会主义的，又是市场驱动的，从而使他们不仅对于“什么”，而且对于“为什么”和“怎么样”产生兴趣。 8.一起学习。一起学习的价值从加州大学伯克利分校的一项试验中显示了出来。该校的

21世纪大学英语教程(第四册)Unit1课文原文

21世纪大学英语读写教程（第四册）Unit1课文原文 《Who Is Great?》 Michal Ryan As a young boy, Albert Einstein did so poorly in school that teachers thought he was slow. The young Napoleon Bonaparte was just one of hundreds of artillery lieutenants in the French Army. And the teenage George Washington, with little formal education, was being trained not as a soldier but as a land surveyor. Despite their unspectacular beginnings, each would go on to carve a place for himself in history. What was it that enabled them to become great? Were they born with something special? Or did their greatness have more to do with timing, devotion and, perhaps, an uncompromising personality? For decades, scientists have been asking such questions. And, in the past few years, they have found evidence to help explain why some people rise above, while others—similarly talented, perhaps—are left behind. Their findings could have implications for us all. Who is great? Defining who is great depends on how one measures success. But there are some criteria. "Someone who has made a lasting contribution to human civilization is great," said Dean Keith Simonton, a professor of psychology at the University of California at Davis and author of the 1994 book Greatness: Who Makes History and Why. But he added a word of caution: "Sometimes great people don't make it into the history books. A lot of women achieved great things or were influential but went unrecognized." In writing his book, Simonton combined historical knowledge about great figures with recent findings in genetics, psychiatry and the social sciences. The great figures he focused on include men and women who have won Nobel Prizes, led great nations or won wars, composed symphonies that have endured for centuries, or revolutionized science, philosophy, politics or the arts. Though he doesn't have a formula to define how or why certain people rise above (too many factors are involved), he has come up with a few common characteristics. A "never surrender" attitude. If great achievers share anything, said Simonton, it is an unrelenting drive to succeed. "There's a tendency to think that they are endowed with something super-normal," he explained. "But what comes out of the research is that there are great people who have no amazing intellectual processes. It's a difference in degree. Greatness is built upon tremendous amounts of study, practice and devotion." He cited Winston Churchill, Britain's prime minister during World War II, as an example of a risk-taker who would never give up. Thrust into office when his country's morale was at its lowest, Churchill rose brilliantly to lead the British people. In a speech following the Allied evacuation at Dunkirk in 1940, he inspired the nation when he said, "We shall not flag or fail. We shall go on to the end...We shall never surrender."
