西蒙顿说，如果事业上取得巨大成就者具有什么共性的话，那就是一种持续不断地追求成功的动力。“人们往往认为他们天生具有一些超常非凡的东西，”他解释道。“但研究结果表明，有的伟人并没有惊人的智力。有的只是程度上的差异而已。伟大是建立在大量的学习、实践和献身精神的基础之上的。”他举出二战时期的英国首相温斯顿?丘吉尔作为一个永不放弃的冒险者的典范。丘吉尔在全国上下士气最为低落的时候被推上台，并出色地领导了英国人民。在1940年盟军敦刻尔克大撤退之后的一次演讲中，他的话激励了全国人民，“我们绝不会衰退、失败。我们将坚持到底……我们永远不会屈服。”

一些人不愿表达感激之情，因为他们觉得这不会受欢迎。我的一个病人在出院几个星期后回到医院感谢他的护士。“我没有更早地回来，”他解释说，“是因为我猜想你们对于人们的感激一定厌烦得要命。”“正好相反，”她回答说，“我很高兴你来。很少有人意识到我们多么需要鼓励，我们从那些鼓励我们的人身上获得了多大的帮助。”我们所给予的感激永远不会过多。因为我们身边的人在构筑他们的人生哲学时所依据的正是这些微笑、我们所表示的感谢和我们表示欣赏的各种小小的示意动作。

一般西方人解决问题的方法是与之搏斗。“进展越困难，硬汉子越向前”这句话便代表了这种解决问题的积极进取的态度。不管是什么问题，不管可以用来解决问题的方法是什么，我们西方人的思维方式所产生的框架总是搏斗。德?博诺医生称之为纵向思维；即那种传统的、按顺序的、亚里士多德式的逻辑思维，坚定地从一步移到下一步，就像玩具积木一块搭在另一块之上。当然，它的缺陷是，如果在任何时刻其中一步没有达到，或者一块积木没有放对，那么整个结构就会坍塌。事情就会陷入僵局，沮丧、紧张和搏斗的情绪就会笼罩心头。横向思维，德?博诺医生说，是对事物进行思考的一种新方法——一种完全避免这种拼搏，用一种完全出人意料的方式解决问题的方法。

某个学生的成绩达不到老师的期望是常有的事。当这种情况发生时，那个学生面对的不是失望、愤怒或恼怒。相反，老师认为这是一次例外，一件偶然的事情，倒霉的一天，一次暂时的失误——而学生相信了她，并消除了疑虑。下一次，他更加努力了，决心做到老师知道他能做到的事。很难精确地确定老师传达的信息：“我期待着最好的成绩，”中到底是哪一部分告诉了孩子。它的一部分包括显示信心的平和语调，言语上的耐心，及没有讽刺、贬低和恼怒等消极因素。期待着最好成绩的老师满怀信心地提问，因为她知道她得到的答案将是正确的，而孩子也感受到了那种信心。

Unit5 Text A 约翰·肯尼迪就职演说 1961年1月20日，星期五 今天我们并不是在庆祝政党的胜利，而是在庆祝自由的胜利；它象征着一个结束，也象征着一个开始；它意味着一种更新，也意味着一种变革。因为我已在你们和上帝面前，宣读了庄重的誓言，与我们的先辈在175年前所拟定的相同。 现在的世界已大不相同了，因为人类的手中掌握着既能消灭人间的各种贫困，又能毁灭所有人类生命的力量。但我们先辈为之奋斗的相同的革命信念，在世界各地仍然有着争论。这个信念就是：人权并非来自国家的慷慨施舍，而是来自上帝的恩赐。 今天，我们不敢忘记我们是第一次革命的继承者。让我们的朋友和敌人都能够听见我此时此地的讲话：(革命的)火炬已经传给了新一代的美国人——他们出生在本世纪，经历过战争的洗礼和严峻而艰苦的和平的考验，为我国悠久的传统感到自豪——他们不愿目睹或容许我国一向坚持，并且今天仍在国内和国际做出承诺的人权渐趋毁灭。 让每个国家都知道，不论是祝福我们的，还是诅咒我们的，为确保自由的存在和胜利，我们将不惜付出任何代价，承受任何沉重负担，应付任何艰难险阻，支持任何朋友，反对任何敌人。 这就是我们的保证——而且还不止于此。 对于那些和我们有着共同文化和精神渊源的昔日盟邦，我们保证会像对待挚友般忠诚。只要团结起来，在许多需要合作的事业中几乎没有什么事是办不到的。我们如果分歧对立，就会一事无成，因为我们在这种情况下，就不敢应付强有力的挑战。 对于那些我们欢迎其加人到自由国家行列中来的新国家，我们将恪守诺言：决不让一种更为严酷的暴政来取代消失的殖民统治，，我们并不总是指望他们会支持我们的观点，但我们始终希望他们能坚决捍卫自身的自由，而且铭记，在历史上，凡是愚蠢地骑在虎背上谋求权力的人，都是以葬身虎口而告终的。 对那些遍布半个地球的身居茅舍和乡村、为摆脱赤贫桎梏而挣扎的人们，我们保证尽最大努力帮助他们自救，不管需要花多长时间——之所以这样做，并不是因为共产党可能在这样做，也不是因为我们需要他们的选票，而是因为这样做是 正确的，，自由社会如果不能帮助众多的穷人，也就无法保护少数的富人。 最后，对于那些与我们敌对的国家，我们提出的不是保证，而是要求：在科学释放出可怕的破坏力量，把全人类卷入到预谋的或意外的自我毁灭的深渊之前，让我们双方重新开始寻求和平。我们不敢以示弱来引诱他们。因为只有当我们毋庸置疑地拥有足够的军备，我们才能毫无疑问地确信永远不会使用这些军备。 所有这些在最初的100天内不会完成，在最初的1000天内也不会完成，在本届政府仔期内也不会完成，甚至我们在这个星球上的有生之年都不会完成。但是让我们开始行动。同胞们，我们的事业最终成败与否，与其说掌握在我的手中，不如说掌握在你们的手中。自从合众国建立以来，每一代美国人都受到过召唤去证明他们对国家的忠诚。曾经响应召唤而献身的美国青年的坟墓遍及全球。 现在，号角已再次吹响——不是召唤我们拿起武器，尽管我们需要武器，不是召唤我们去作战，虽然我们严阵以待——而是召唤我们为迎接黎明而肩负起漫长斗争的重任，年复——年，“从希望中获得欢乐，在苦难中保持坚韧”，去反对人类共同的敌人：专制、贫困、疾病和战争本身。我们能不能结成一个包括东西南北各方的全球大联盟，以反抗这些敌人，确保人类有更为富足的生活呢?你们愿意加入这场历史性的斗争吗? 在悠久的世界历史中，只有少数几代人被赋·子这种使命，能够在面临最大的危机时捍卫自由，、我们在这场奋斗中所奉献的精力、信念和献身精神，将照亮我们的国家和所有

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."
