【篇一】The Historical Significance of American Revolution

The ways of history are so intricate and the motivations of human actions so complex that it is always hazardous to attempt to represent events covering a number of years, a multiplicity of persons, and distant localities as the expression of one intellectual or social movement; yet the historical process which culminated in the ascent of Thomas Jefferson to the presidency can be regarded as the outstanding example not only of the birth of a new way of life but of nationalism as a new way of life.

The American Revolution represents the link between the seventeenth century, in which modern England became conscious of itself, and the awakening of modern Europe at the end of the eighteenth century. It may seem strange that the march of history should have had to cross the Atlantic Ocean, but only in the North American colonies could a struggle for civic liberty lead also to the foundation of a new nation.

Here, in the popular rising against a “tyrannical” government, the fruits were more than the securing of a freer constitution. They included the growth of a nation born in liberty by the will of the people, not from the roots of common descent, a geographic entity, or the ambitions of king or dynasty.

With the American nation, for the first time, a nation was born, not in the dim past of history but before the eyes of the whole world.

【篇二】译文

美国革命的历史意义

历史的进程是如此错综复杂，人类行为的动机是如此令人费解，以至于想把那些时间跨度大、涉及人数多、空间范围广的事件描述成为一个智者或一场社会运动的表现的企图是危险的。然而以托马斯·杰弗逊登上总统宝座为高 潮的那一段历史过程可以被视为一个特殊的例子。在这段历史时期里不仅诞生了新的生活方式，而且民族主义成为了一种新的生活方式。

美国独立战争成为联结17世纪现代英格兰的自我意识和18世纪末现代欧洲的觉醒的纽带。历史的行程需要跨越大西洋，这看起来似乎有些奇怪，但却只有在北美殖民地为民权和自由的斗争才能导致新国家的建立。

这里，反对“暴 政”的民众起义的成果不仅是获得一个包含更多自由的宪法，还包括了一个依照人民的意愿诞生在自由中的国家的成长。这个国家不是基于血缘、地理、君主或王朝的野心。

由于有了美国，第一次一个国家的诞生不是发生在历史模糊的过去，而是在全世界人们的眼前。

【篇三】Children's Numerical Skills

People appear to be born to compute. The numerical skills of children develop so early and so inexorably that it is easy to imagine an internal clock of mathematical maturity guiding their growth. Not long after learning to walk and talk, they can set the table with impressive accuracy -- one knife, one spoon, one fork, for each of the five chairs.

Soon they are capable of noting that they have placed five knives, spoons and forks on the table and, a bit later, that this amounts to fifteen pieces of silverware. Having thus mastered addition, they move on to subtraction. It seems almost reasonable to expect that if a child were secluded on a desert island at birth and retrieved seven years later, he or she could enter a second-grade mathematics class without any serious problems of intellectual adjustment.

Of course, the truth is not so simple. This century, the work of cognitive psychologists has illuminated the subtle forms of daily learning on which intellectual progress depends. Children were observed as they slowly grasped -- or, as the case might be, bumped into -- concepts that adults take for granted, as they refused, for instance, to concede that quantity is unchanged as water pours from a short stout glass into a tall thin one.

Psychologists have since demonstrated that young children, asked to count the pencils in a pile, readily report the number of blue or red pencils, but must be coaxed into finding the total. Such studies have suggested that the rudiments of mathematics are mastered gradually, and with effort. They have also suggested that the very concept of abstract numbers - the idea of a oneness, a twoness, a threeness that applies to any class of objects and is a prerequisite for doing anything more mathematically demanding than setting a table - is itself far from innate.

【篇四】译文

儿童的数学能力

人似乎生来就会计算。孩子们使用数字的技能发展得如此之早和如此必然，很容易让人想象有一个内在精确而成熟的数字钟在指导他们的成长。孩子们在学会走路和说话后不久，就能以令人惊叹的准确布置桌子——五把椅子前面分别摆上一把刀、一个汤匙、一把叉子。很快地，他们就能知道他们已在桌面上摆放了五把刀、五个汤匙、五把叉子。

没有多久，他们就又能知道这些东西加起来总共是15把银餐具。如此这般地掌握了加法之后，他们又转向减法。有一种设想几乎顺理成章，那就是，即使一个孩子一出生就被隔绝到荒岛上，七年后返回世间，也能直接上小学二年级的数学课，而不会碰到任何智力调整方面的大 麻烦。

当然，事实并没有这么简单。本世纪认知心理学家的工作已经揭示了智力发展所依赖的日常学习的微妙形式。他们观察到孩子们缓慢掌握那些成年人认为理所当然的概念的过程，或者是孩子们偶然遇到这些概念的过程。他们也观察到孩子们拒绝承认某些常识的情况。比如：孩子们拒绝承认当水从短而粗的瓶中倒入细而长的瓶子中时，水的数量没有变化。

心理学家们而后又展示一个例子，即：让孩子们数一堆铅笔时，他们能顺利地报出蓝铅笔或红铅笔的数目，但却需诱导才能报出总的数目。此类研究表明：数学基础是经过逐渐努力后掌握的。他们还表示抽象的数字概念，如可表示任何一类物品并且是在做比摆桌子有更高数学要求的任何事时都必备的一、二、三意识，远远不是天生就具备的。
