Growth That Starts From Thinking It seems to me a very difficult thing to put into words the beliefs we hold and what they make you do in your life. I think I was fortunate because I grew up in a family where there was a very deep religious feeling. I don’t think it was spoken of a great deal. It was more or less taken for granted that everybody held certain beliefs and need...
Diane Ackerman / 迪安.阿克曼 The word “discovery” literally means, uncovering something that’s hidden from view. But what really happens is a change in the viewer. The familiar offers comfort few can resist, and fewer still want to disturb. But as relatively recent inventions such as the telescope and microscope have taught us, the unknown has many layers. Every truth has g...
A Wet Sunday In A Country Inn A wet Sunday in a country inn ! Whoever has had the luck to experience one(1) can alone judge of(2) my situation. The rain pattered against the casements; the bells tolled for church with a melancholy sound. I went to the windows in quest of something to amuse the eye; but it seemed as if I had been placed completely out of the reach of ail amus...

Cells and Temperature Cells cannot remain alive outside certain limits of temperature, and much narrower limits mark the boundaries of effective functioning. Enzyme systems of mammals and birds are most efficient only within a narrow range around 37 ℃; a departure of a few degrees from this value seriously impairs their functioning. Even though cells can survive wider fluctu...
I grew up in a small town where the elementary school was a ten-minute walk from my house and in an age when children could go home for lunch. At the time, I did not consider this a luxury, although today it certainly would be. I took it for granted that mothers were the sandwich-makers and the homework monitors. I never questioned that this ambitious, intelligent woman, w...
Relish the Moment Tucked away in our subconsciousness is an idyllic vision. We see ourselves on a long trip that spans the moment. We are traveling by train. Out the windows, we drink in the passing scene of cars on nearby highways, of children waving at a crossing, of cattle grazing on a distant hillside, of smoke pouring from a power plant, of row upon row of corn ad wheat...
The Salinity of Ocean Waters If the salinity of ocean waters is analyzed, it is found to vary only slightly from place to place. Nevertheless, some of these small changes are important. There are three basic processes that cause a change in oceanic salinity. One of these is the subtraction of water from the ocean by means of evaporation – conversion of liquid water to ...
After thirty years of married happiness, he could still remind himself that Victoria was endowed with every charm except the thrilling touch of human frailty. Though her perfection discouraged pleasures, especially the pleasures of love, he had learned in time to feel the pride of a husband in her natural frigidity. For he still clung, amid the decay of moral platitudes, to ...
The American Civil War The military aspect of the United States Civil War has always attracted the most attention from scholars. The roar of gunfire, the massed movements of uniformed men, the shrill o f bugles, and the drama of hand to hand combat have facinated students of warfare for a century. Behind the lines, however, life was less spectacular. It was the story of back...
Treasure in Sunken Ships Of the tens of thousands of ships on the ocean bottom, only a handful, less than 1 percent, contain negotiable treasure, such as gold and jewels. Most give us a different priceless treasure — history. A sunken ship lies in trust, preserved in the airless environment of the sea and those in deep water are especially well protected. No dry land s...
On Motes and Beams It is curious that our own offenses should seem so much less heinous than the offenses of others. I suppose the reason is that we know all the circumstances that have occasioned them and so manage to excuse in ourselves what we cannot excuse in others. We turn our attention away from our own defects, and when we are forced by untoward events to consider th...
新东方优美背诵短文50篇 Unit43:Statistics 43.Statistics There were two widely divergent influences on the early development of statistical methods. Statistics had a mother who was dedicated to keeping orderly records of government units (states and statistics come from the same Latin root status) and a gentlemanly gambling father who relied on mathematics to increase his skil...
The War between Britain and France In the late eighteenth century, battles raged in almost every corner of Europe, as well as in the Middle East,South Africa, the West Indies, and Latin America. In reality, however, there was only one major war during this time,the war between Britain and France. All other battles were ancillary to this larger conflict, and were often at lea...
Youth Youth is not a time of life; it is a state of mind; it is not a matter of rosy cheeks, red lips and supple knees; it is a matter of the will, a quality of the imagination, a vigor of the emotions; it is the freshness of the deep springs of life. Youth means a temperamental predominance of courage over timidity, of the appetite for adventure over the love of ease. This ...

阅读好书 我再说一遍，把你的一部分空闲时光用来培养阅读好书的爱好吧。那些设法把自己培养成为真正爱好读书的人，确实是幸运的。因为爱读书的人比之别人有着明显的好处。只要手头有书，他们就从来不知寂寞。书越好，读来越是津津有味。他们从好书中不但得到乐趣，而且受到很多教益。他们从中获得的那种精神食粮，从其他地方是很难得到的。即使是在工作休息时，通过读书，他们的工作效率也能更加提高，尽管...
Be Happy! “The days that make us happy make us wise.”—-John Masefield when I first read this line by England’s Poet Laureate, it startled me. What did Masefield mean? Without thinking about it much, I had always assumed that the opposite was true. But his sober assurance was arresting. I could not forget it. Finally, I seemed to grasp his meaning and realized that here...
Population Growth The growth of population during the past few centuries is no proof that population will continue to grow straight upward toward infinity and doom. On the contrary, demographic history offers evidence that population growth has not been at all constant. According to paleoecologist Edward Deevey, the past million years show three momentous changes. The first,...
中文翻译: 罕见的化石记录 胚胎与幼体被保存下来在化石记录中是少见的事情。微小纤细的骨骼 通常在石化前就被食腐肉的动物拆散了，或者被风化作用破坏掉了。 鱼龙比起陆地的动物 有更大的几率被保存下来，因为它们作为海洋动物常生活在腐蚀性较小的环境中。 但是它们的石化需要一系列因素：软组织的腐烂速度缓慢，很少被其他动物残食，缺少混杂、冲走小骨头的快速水流和波浪，以及相当快地被掩埋。 当这些...
