研究生英语作文范文：Evolution of Sleep

Sleep is very ancient. In the electroencephalographic sense we share it with all the primates and almost all the other mammals and birds: it may extend back as far as the reptiles.

There is some evidence that the two types of sleep, dreaming and dreamless, depend on the life-style of the animal, and that predators are statistically much more likely to dream than prey, which are in turn much more likely to experience dreamless sleep. In dream sleep, the animal is powerfully immobilized and remarkably unresponsive to external stimuli.

Dreamless sleep is much shallower, and we have all witnessed cats or dogs cocking their ears to a sound when apparently fast asleep. The fact that deep dream sleep is rare among prey today seems clearly to be a product of natural selection, and it makes sense that today, when sleep is highly evolved, the stupid animals are less frequently immobilized by deep sleep than the smart ones. But why should they sleep deeply at all? Why should a state of such deep immobilization ever have evolved? Perhaps one useful hint about the original function of sleep is to be found in the fact that dolphins and whales and aquatic mammals in general seem to sleep very little. There is, by and large, no place to hide in the ocean. Could it be that, rather than increasing an animal's vulnerability, the function of sleep is to decrease it? Wilse Webb of the University of Florida and Ray Meddis of London University have suggested this to be the case. It is conceivable that animals who are too stupid to be quiet on their own initiative are, during periods of high risk, immobilized by the implacable arm of sleep. The point seems particularly clear for the young of predatory animals. This is an interesting notion and probably at least partly true.

睡眠的进化

睡眠是古老的。 从脑电图上看，我们人类和所有灵长目动物以及几乎所有的哺乳动物 和鸟类都一样需要睡眠;甚至爬行类动物也有睡眠。 有证据显示，有梦睡眠和无梦睡眠这两种类型的睡眠取决于该动物的生活方式。 从统计上看，食肉动物比被捕食动物有更多的 有梦睡眠，而被捕食动物更多地无梦睡眠。

动物在有梦睡眠时，被有效地解除动作能力， 并且对外界刺激缺乏反应。 无梦睡眠则要浅得多。 我们都看到过猫和狗在显然的酣睡中， 有一点响动耳朵就会竖起来。 被捕食动物很少有深度的有梦睡眠，这看来显然是自然选择 的结果。

而且这一点是有道理的：当睡眠高度进化以后，愚笨的动物比聪明的动物更少在 深度睡眠状态下丧失动作能力。

但是动物为什么要进入深度睡眠呢?为什么这样的无动作状 态也会进化出来呢? 海豚、鲸鱼以及水生哺乳动物睡眠都极少，这一事实可以给睡眠的根本 功能提供有用的线索。 海洋中是没有藏身之处的。 会不会是这样，睡眠不但不增加动物受 伤害的可能性，反而是减少了这种可能性呢?佛罗里达大学的 Wilse Webb 和伦敦大学的 Ray Meddis 认为情况就是如此。 可以想像得出，在危险的时刻，那些由于太愚笨而不能自动保 持安静的动物，会不由自主地变得动弹不得。 这一点在食肉动物的幼兽身上表现得特别明 显。 这是一个很有意思的看法，它至少部分是正确的。

研究生英语作文范文：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.

全文翻译：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。

研究生英语作文范文：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.

全文翻译：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 人想象有一个内在的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。

考研的好处 英语作文

写作思路 ：可以结合社会的实际情况，直接给出考研的好处， 比如考研可以丰富知识，提高能力；增强竞争力等等。

正文：

There are many advantages of postgraduate entrance examination, as follows:

考研有很多的好处，具体如下：

Enrich knowledge, improve ability: undergraduate learning is relatively more extensive, each knowledge will involve some, there are many students feel that they have learned everything but nothing. Graduate students will have a more systematic and in-depth study of a specific field, which will undoubtedly enrich their knowledge reserves, make them understand the field better and form their own knowledge system.

丰富知识，提高能力：本科的学习相对来说更加泛化，各个知识都会涉及一些，有很多同学觉得自己什么都学了但又什么都没学会。研究生会对某一具体领域进行更加系统深入的学习，无疑会丰富自己的知识储备，使得自己对所学领域更加了解，形成自己的知识体系。

Enhance competitiveness: academic qualifications still play a very important role in this society, especially the increasing number of college students and graduate students. Some units will have academic qualifications when recruiting. Even if they say that their ability is strong, how can they get into the door without the stepping stone? Although it is said that even if you go in, you will not stay, but you also have more chances to enter.

增强竞争力：学历在这个社会还是起到非常重要的作用的，尤其大学生、研究生越来越多，有一些单位招聘时会有学历的要求，即便说自己的能力再强，但没有那块敲门砖，自己又如何进去那扇门呢？虽然说即便自己进去也不是百分百就会留下，但自己也拥有了更多进门的机会。

Low cost choice intention city life: everyone has their own city, but many people can not go to their ideal city for various reasons, especially the current life pressure is great, dare not freely choose the ideal city.

低成本选择意向城市生活：每个人都有自己向往的城市，但很多人由于各种原因并不能去到自己的理想城市，尤其是当下生活压力极大，更不敢自由选择理想城市。

But the postgraduate entrance examination is actually a shortcut to experience life elsewhere. The living cost of postgraduate education is low. You can choose to study in the city and live there for two or three years. Even if you won't stay in the future, you will experience it and have no regrets.

但考研其实是一个体验别处生活的捷径，读研的生活成本较低，可以选择自己喜欢城市的学习，在那里生活两年或三年，即便未来不会留下，自己也体验过，不会有遗憾。

越来越多的大学生选择考研目的前景四级英语作文

There are more and more college graduates choose to continue their tertiary education nowadays. At their graduation, they take the entrance examinations for the postgraduate studies, and try to earn higher degrees. This situation has both its pros and cons.

The phenomenon that more students are willing to earn higher degrees is definitely a good sign for the economy and for the future of the country. Scientific and technological developments, social evolution, understandings towards nature and history are all progressing. They need people of deeper studies to carry further. Traditional ideas in many areas are becoming obsolete and the society wants fresh thoughts to remodel it, and make it a better environment for human beings. All these will be possible only based on further studies, researches and more specialized work, rather than relying on the basic disciplines of past knowledge.

On the other hand, it also reflects a trend in which the undergraduates have intense competition in the employment market. Increasing numbers of them are unable to find a job of their studies at the graduation, and have to give up what they have learned and go into other professions only to be surviving. This is a huge waste of the national education resources, particularly considering that four years ago these students took the positions in the colleges and deprived their competitors' chance of entering tertiary educations. No winners amongst them all, the colleges, the undergradtates, and those "failed" competitors, as the change into other areas happen.

One very likely scenario is that the problem of intense competition is to be deferred rather than solved, i.e. that it is carried onto the next level. If all the Bachelors are moving into master studies, then the job position competition may temporarily be calmed now, but start again in three years when they are graduating as Masters, or five years later as Doctors.
