Only In Sleep — by Sara Teasdale 只在睡梦中–莎拉·蒂斯黛尔 Only in sleep, I see their faces 在睡梦中，我才能看得到儿时的玩伴 Children I played with when I was a child 他们的笑脸如此真切 She comes back with her brown hair braided 她绑着棕色的发带向我跑来 He with ringlets warm and wild 他还是一头亲切又不羁的卷发 Only in sleep, Time is forgotten 在睡梦中时间才被遗忘 ...
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 skill at playing the odds in games of chance. T...
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 ...
Brighton Beach By Allan Taylor 《布莱顿海滩》–艾伦·泰勒 Young girl, so pretty 年轻的女孩，如此美丽 Young boy, not a hair on his face 年轻的男孩，脸上还未有胡须 They’re looking out at the big wide world 他们面朝着广阔天地 This was their time, this was their place 这是他们的时间和领地 He said, “One day I will make you mine, we’ll be together till the en...
Archaeology Archaeology is a source of history, not just a bumble auxiliary discipline. Archaeological data are historical documents in their own right, not mere illustrations to written texts, Just as much as any other historian, an archaeologist studies and tries to reconstitute the process that has created the human world in which we live – and us ourselves in so fa...
Lesson 4:Electricity The modern age is an age of electricity. People are so used to electric lights, radio, televisions, and telephones that it is hard to imagine what life would be like without them. When there is a power failure, people grope about in flickering candlelight, cars hesitate in the streets because there are no traffic lights to guide them, and food spoils in ...
Skyscrapers and Environment In the late 1960’s, many people in North America turned their attention to environmental problems, and new steel-and-glass skyscrapers were widely criticized. Ecologists pointed out that a cluster of tall buildings in a city often overburdens public transportation and parking lot capacities. Skyscrapers are also lavish consumers, and wasters...
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 least partially related to its anta...
Museums From Boston to Los Angeles, from New York City to Chicago to Dallas, museums are either planning, building, or wrapping up wholesale expansion programs. These programs already have radically altered facades and floor plans or are expected to do so in the not-too-distant future. In New York City alone, six major institutions have spread up and out into the air space ...
19.children’s numerical skills people appear to 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 impress accuracy—one knife, one spoon, one fork, for each of the five ...
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 w...
“She had forgotten how the August night” By Edna St. Vincent Millay 她已经忘记了那个八月的夜晚–埃德娜·文森特·默蕾 She had forgotten how the August night was level as a lake beneath the moon 她已经忘记了那个八月的夜晚，夜平静的像月下的湖面 In which she swam a little, losing sight of shore 她迷失在夜里，像是畅游在湖中，转眼间便离了岸边 And how the boy, who wa...
Lesson 6:Television Television—–the most pervasive and persuasive of modern technologies, marked by rapid change and growth-is moving into a new era, an era of extraordinary sophistication and versatility, which promises to reshape our lives and our world. It is an electronic revolution of sorts, made possible by the marriage of television and computer tec...
Telecommuting Telecommuting– substituting the computer for the trip to the job —- has been hailed as a solution to all kinds of problems related to office work. For workers it promises freedom from the office, less time wasted in traffic, and help with child-care conflicts. For management, telecommuting helps keep high performers on board, minimizes tardin...
Vision by Human vision like that of other primates has evolved in an arboreal environment. In the dense complex world of a tropical forest, it is more important to see well that to develop an acute sense of smell. In the course of evolution members of the primate line have acquired large eyes while the snout has shrunk to give the eye an unimpeded view. Of mammals only human...
Botany Botany, the study of plants, occupies a peculiar position in the history of human knowledge. For many thousands of years it was the one field of awareness about which humans had anything more than the vaguest of insights. It is impossible to know today just what our Stone Age ancestors knew about plants, but form what we can observe of pre- industrial societies that s...
Modern American Universities Before the 1850’s, the United States had a number of small colleges, most of them dating from colonial days. They were small, church connected institutions whose primary concern was to shape the moral character of their students. Throughout Europe, institutions of higher learning had developed, bearing the ancient name of university....
What’s the point, wasting time 有什么意义？不过是浪费时间 But how many times you stand up for yourself 但多少次你为自己打气 Make a point, you have a reason 你说，你有自己的理由 You know, it’s not fair 你知道,世界并不公平 Your life, belongs to nobody else 你的生活，不属于其他人。 So don’t tell me there is nobody you want to hold 所以别告诉我，世上没有你想守护的人 You know you...
The Origin of Sports When did sport begin? If sport is, in essence, play, the claim might be made that sport is much older than humankind, for , as we all have observed, the beasts play. Dogs and cats wrestle and play ball games. Fishes and birds dance. The apes have simple, pleasurable games. Frolicking infants, school children playing tag, and adult arm wrestlers ar...
Prepare for disappointed 做好失望的准备 I only needed a soul 我仅仅需要一个伴侣 To share, to kiss and to hold 来接受我的轻吻和拥抱 But only found this dark hole 但我只有这空荡的房间 Someone unbearably cold 和这难忍的孤寂 And though I tried to reach through 我觉得我曾尝试过 Tried to see what makes you you 来发现你为什么这么美丽 You closed all windows and doors 但你没有向我敞...
