21世纪大学英语4 课文翻译完型填空及句子翻译Unit1A谁是伟大的？迈克尔?赖恩阿尔伯特?爱因斯坦小时候在学校里的成绩很糟糕，老师们都认为他迟钝。

拿破仑?波拿巴年轻时只是法国陆军中几百名炮兵中尉中的一几乎没有受过正规教育的乔治?华盛顿，十几岁时不是受训当兵而是受训做土地测量员。

尽管他们的起步平淡无奇，但是每个人后来都为自己在历史上赢得了一席之地。

是什么使得他们变得伟大呢？是他们生来就具备一些特殊的东西？还是他们的伟大与时机掌握、献身精神和也许是一种坚定的个性更为有关？几十年来，科学家们一直在问这样的问题。

在过去几年里，他们已经发现了证据，这些证据有助于解释为什么有些人出类拔萃，而另外的人——也许同样很有才华——却被甩在了后面。

他们的发现可能对我们所有的人都有启示。

谁是伟大的？伟人的定义取决于如何衡量成功。

但标准还是有一些的。

“对人类文明作出永久性贡献的人是伟大的，”基思?西蒙顿院长说。

他是加州大学戴维斯分校的一名心理学教授，1994年出版的《伟大：谁创造历史，以及为什么》一书的作者。

但他又提醒说：“有时侯伟人并没有被载入史册。

许多女性取得了巨大成就，或者颇具影响力，但却没有得到承认。

”在这本书的写作中，西蒙顿把有关伟大人物的历史知识和遗传学、精神病学及社会科学领域的最新发现融合在了一起。

他所聚焦的伟人包括获得过诺贝尔奖、领导过伟大的国家或赢得过战争、谱写过流芳百世的交响乐或在科学、哲学、政治学或艺术上引起过革命性巨变的男性和女性。

虽然他没有一个公式来解释某些人怎样或为什么出类拔萃（其中涉及的因素太多了），但他却提出了一些共同的特点。

一种“永不屈服”的态度。

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。
