精美短文 第87篇:Pines松树
松树 松树几乎总是长在凌乱荒凉地地方，但它却把周围的景色点缀得井井有条，蔚然可观。低地上的树木会东倒西歪，虽说使它们弓腰曲背的，不过是草地上吹过的一阵阵微风；或者，它们的躯干歪到一边，不过时由于一排野樱草的影响。可是，尽管风暴和寻崩姿意摧残，尽管松树所能依附的只是陡壁上一块凸出的岩石，它依然长得笔挺。从它初发的嫩枝旁沿茎插一根笔直的杆子，只要这树活着，杆子将一直指着地的中心。...
英语范文背诵 (8):Love of Life
Love of Life Two men walked slowly, one after the other, through the low water of a river. It ran cold over their feet. They had blanket packs on their backs; guns, but no bullets; matches, but no food. Suddenly the man behind fell over a stone, hurt his foot badly and called: “Hey, Bill, I’ve hurt my foot.” Bill continued without looking back. The man was ...

James Watt And The Teakettle A little Scotch boy was sitting in his grandmother’s kit- chen. He was watching the red flames in the wide open fire- place and quietly wondering about the causes of things.

精美短文 第3篇:American Revolution
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...
精美短文 第27篇:Icebergs冰山
Icebergs Icebergs are among nature’s most spectacular creations, and yet most people have never seen one. A vague air of mystery envelops them. They come into being — somewhere — in faraway, frigid waters, amid thunderous noise and splashing turbulence, which in most case no one hears or sees. They exist only a short time and then slowly waste away just as...

精美短文 第81篇:Growth That Starts From Thinking
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...
精美短文 第106篇:乡村客栈一个阴雨的星期天
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...
精美短文 第10篇:Cells and Temperature细胞与温度
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...
英语范文背诵 (4):My mother's Gift
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...
精美短文 第73篇:The Salinity of Ocean Waters海水盐度
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.

精美短文 第59篇:The American Civil War美国内战
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...
精美短文 第78篇:Treasure in Sunken Ships 沉船中的宝藏
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...

精美短文 第89篇:Reading Good Books阅读好书
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...
精美短文 第46篇:Population Growth人口增长
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,...
精美短文 第1篇:A Rare Fossil Record
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...

Cohesion-tension Theory Atmospheric pressure can support a column of water up to 10 meters high. But plants can move water much higher; the sequoia tree can pump water to its very top more than 100 meters above the ground. Until the end of the nineteenth century, the movement of water in trees and other tall plants was a mystery. Some botanists hypothesized that the living c...
