Coal-fired Power Plants The invention of the incandescent light bulb by Thomas A. Edison in 1879 created a demand a cheap, ily available fuel with which to generate large amounts of electric power. Coal seemed to fit the bill, and it fueled the earliest power stations (which were set up at the end of the nineteenth century by Edison himself. As more power plants were constructed throughout the country, the reliance on coal increased. Since the First World War, coal-fired power plants have ed about half of the electricity produced in the ed States each year. In 1986 such plants had a combined generating capacity of 9, 000 megawatts and consumed 83 percent of the nearly 900 million tons of coal mined in the country that year. Given the uncertainty in the future growth of nuclear power and in the supply of oil and natural gas, coal-fired power plants could well provide up to 70 percent of the electric power in the ed States by the end of the century. Yet, in spite of the fact that coal has long been a source of electricity and may remain one many years (coal represents about 80 percent of ed States fossil-fuel reserves), it has actually never been the most desirable fossil fuel power plants. Coal contains less energy per of weight than natural gas or oil; it is difficult to transport, and it is associated with a host of environmental issues, among them acid rain. Since the late 1960's problems of emission control and waste disposal have sharply reduced the appeal of coal-fired power plants. The cost of ameliorating these environmental problems along with the rising cost of building a facility as large and complex as a coal-fired power plant, have also made such plants less attractive from a purely economic perspective. Changes in the technological base of coal-fired power plants could restore their attractiveness, however. Whereas some of these changes are evolutionary and are intended mainly to increase the productivity of existing plants, completely new technologies burning coal cleanly are also being developed. 757老美地道美语:购物常用语句 -01-7 ::30 来源: 1.

I like to think she would have gone out a Chinese dinner,her favorite food.I'm guessing.I'll never know.It's those little things left undone that would make me angry if I knew that my hours were limited.Angry because I put off seeing good friends whom I was going to get in touch with someday.Angry because I hadn't written certain letters that I intended to write one of these days.Angry and sorry that I didn't tell my husband and daughter often enough how much I truly love them.I'm trying very hard not to put off,hold back,or save anything that would add laughter and lustre8) to our lives.And every morning when I open my eyes,I tell myself that every day,every minute,every breath truly,is...a gift from God. 970

Deep in the Shady Sadness of a Vale DEEP in the shady sadness of a vale Far sunken from the healthy breath of morn, Far from the fiery noon, and eve’s one star, Sat gray-hair’d Saturn, quiet as a stone, Still as the silence round about his lair; est on est hung about his head Like cloud on cloud. No stir of air was there, Not so much life as on a summer’s day Robs not one light seed from the feather’d grass, But where the dead leaf fell, there did it rest. A stream went voiceless by, still deadened more By reason of his fallen divinity Sping a shade the Naiad ’mid her reeds Press’d her cold finger closer to her lips. Along the margin-sand large foot-marks went, No further than to where his feet had stray’d, And slept there since. Upon the sodden ground His old right hand lay nerveless, listless, dead, Unsceptred; and his realmless eyes were closed; While his bow’d head seem’d list’ning to the Earth, His ancient mother, some comt yet. It seem’d no ce could wake him from his place; But there came one, who with a kindred hand Touch’d his wide shoulders, after bending low With reverence, though to one who knew it not. She was a Goddess of the infant world; By her in stature the tall Amazon Had stood a pigmy’s height she would have ta’en Achilles by the hair and bent his neck; Or with a finger stay’d Ixion’s wheel. Her face was large as that of Memphian sphinx, Pedestal’d haply in a palace court, When sages look’d to Egypt their lore. But oh! how unlike marble was that face How beautiful, if sorrow had not made Sorrow more beautiful than Beauty’s self. There was a listening fear in her regard, As if calamity had but begun; As if the vanward clouds of evil days Had spent their malice, and the sullen rear Was with its stored thunder labouring up. One hand she press’d upon that aching spot Where beats the human heart, as if just there, Though an immortal, she felt cruel pain The other upon Saturn’s bended neck She laid, and to the level of his ear Leaning with parted lips, some words she spake In solemn tenour and deep organ tone Some mourning words, which in our feeble tongue Would come in these like accents; O how frail To that large utterance of the early Gods! “Saturn, look up!—though wheree, poor old King? “I have no comt thee, no not one “I cannot say, “O wheree sleepest thou?’ “ heaven is parted from thee, and the earth “Knows thee not, thus afflicted, a God; “And ocean too, with all its solemn noise, “Has from thy sceptre pass’d; and all the air “Is emptied of thine hoary majesty. “Thy thunder, conscious of the new command, “Rumbles reluctant o’er our fallen house; “And thy sharp lightning in unpractised hands “Scorches and burns our once serene domain. “O aching time! O moments big as years! “All as ye pass swell out the monstrous truth, “And press it so upon our weary griefs “That unbelief has not a space to breathe. “Saturn, sleep on—O thoughtless, why did I “Thus violate thy slumbrous solitude? “Why should I ope thy melancholy eyes? “Saturn, sleep on! while at thy feet I weep.” 983

SalariesEconomists and experts on wages have long tried to discoverwhat factors were influencing people’s salaries.Most of the factors they listed one or two centuries agoare still important today.One of those is education college graduates have earnedand are still earning more than workerswho have only finished high school,and high-school graduates earn more than workerswho didn’t complete their studies there.The difficulty and length of preparation a professionalso plays a part in the size of the salary.Danger and responsibility make a difference too —the man or woman in charge of a project,the person perming a difficult or dangerous task,the airplane pilot responsible many human lives,usually get a proper compensation their pains.And yet there are exceptions to those rules.Due to the needs of modern industry,technicians with no college education are now commanding high salaries,much closer to the college graduates'salariesthan they used to be in the past.And there are many jobs in which dangerdoesn’t bring much compensation.Why doesn’t a fireman earn more than a postal clerk, example?And what about the policeman and the coal miner,who risk their lives a modest salary?The answer is simple.Actually, salaries are governed by a combination of factors,the most important being one known as the law of supply and demand,which says that the value of goods and servicesis determined by the quantity availablecompared with the number of possible buyers.If there are more chickens on the market than people wishing to buy them,the price of poultry goes down.If the number of specialized engineersis much larger than the number of positions open to them,the salaries drop even the most impressive applicants. 57

我们都承认在我们曰常活动中那么忙碌的自我,并不完全是真正的自我;我们相信我们在生活的追求中已经失掉了一些东西The only problem unconsciously assumed by all Chinese philosophers to be of any importance is How shall we enjoy life, and who can best enjoy life? No perfectionism, no straining after the unattainable, no postulating of he unknowable; but taking poor, modal human nature as it is, how shall we organize our life so that we can woke peacefully, endure nobly and live happily?Who are we? That is first question. It is a question almost impossible to answer. But we all agree with the busy self occupied in our daily activities is not quite the real self. We are quite sure we have lost something in the mere pursuit of living. When we watch a person running about looking something in a field, the wise man can set a puzzle all the spectator to solve what has that person lost? Some one thinks is a watch; another thinks it is a diamond brooch; and others will essay other guesses. After all the guesses have failed, the wise man who really doesn't know what the person is seeking after, tells the company" I'll tell you. He has lost some breath." And no one can deny that he is right. So we often get our true self in the pursuit of living, like a bird getting its own danger in pursuit of a mantis which again gets its own danger in pursuit of another. 987
