单选题A little more than a century ago, Michael Faraday,the noted British physicist, managed to gain audience with a group of high government officials, to demonstrate an electro-chemical principle, in the hope of gaining support for his work． After observing the demonstrations closely,one of the officials remarked bluntly,"It's a fascinating demonstration, young man, but just what practical application will come of this?" "I don't know,"replied Faraday, "but I do know that 100 years from now you'll be taxing．them．" From the demonstration of a principle to the marketing of products derived from that principle is often a long, involved series of steps．The speed and effectiveness with which these steps are taken are closely related to the history of management, the art of getting things done．Just as management applies to the wonders that have evolved from Faraday and other inventors, so it applied some 4,000 years ago to the working of the great Egyptian and Mesopotamian import and export firms…to Hannibal's remarkable feat of crossing the Alps in 218 B.C.with 90,000 foot soldiers, 12,000 horsemen and a"conveyor belt"of 40 elephants…or to the early Christian Church, with its world—shaking concepts of individual freedom and equality． These ancient innovators were deeply involved in the problems of authority,divisions of labor, discipline, unity of command, clarity of direction and the other basic factors that are so meaningful to management today．But the real impetus to management as an emerging profession W3S the Industrial Revolution．Originating in 18-century England, it was triggered by a series of classic inventions and new processes；among them John Kay's flying Shuttle in 1733, James Hargrove's Spinning Jenny in 1770, Samuel Compton's Mule Spinner in 1779 and Edmund Cartwright's Power Loom in 1785．

单选题When an invention is made, the inventor has three possible 61 of action open to him; he can give the invention to the world by publishing it, keep the idea 62 , or patent it. A 63 patent is the result of a bargain 64 between an inventor and the state, but the inventor gets a limited period of monopoly and publishes full details of his invention to the public after that period 65 . Only the most exceptional circumstances 66 the lifespan of a patent 67 to alter this normal process of events. The longest extension ever 68 was to Georges Valensi; his 1939 patent for color TV receiver circuit was extended until 1971 because for most of the patent's normal life there was no color TV to 69 and thus no hope for reward for the invention. Because a patent remains permanently 70 after it has terminated, the shelves of the library attached to the 71 office contain details of literally millions of ideas that are free for anyone to use and, if 72 than half a century, sometimes even re-patent. Indeed, patent experts often advise anyone 73 to avoid the high cost of conducting a search through 74 patents that the one sure way of violation of any other inventor's fight is to plagiarize a dead patent. Likewise, because publication of an idea in any other form 75 invalidates further patents on that idea. It is traditionally 76 to take ideas from other areas of print. Much modem technological advance is 77 on these presumptions of legal security. Anyone closely 78 in patents and inventions soon learns that most "new" ideas are, in fact, as old as the hills. It is their reduction to commercial practice, either through necessity or dedication, or through the availability of new technology, 79 makes news and money. The basic patent for the theory for magnetic recording dates back to 1886. Many of the original ideas behind television originate 80 the late 19th and early 20th century. Even the Volkswagen rear engine car was anticipated by a 1904 patent for a cart with the horse at the rear.

单选题Despite their many differences of temperament and of literary perspective, Emerson, Thoreau, Hawthorne, Melville, and Whitman share certain beliefs. Common to all these writers is their humanistic perspective. Its basic premises are that humans are the spiritual center of the universe and that in them alone is the clue to nature, history, and ultimately the cosmos itself. Without denying outright the existence either of a deity or of brute matter, this perspective nevertheless rejects them as exclusive principles of interpretation and prefers to explain humans and the world in terms of humanity itself. This preference is expressed most clearly in the transcendentalist principle that the structure of the universe literally duplicates the structure of the individual self. Therefore, all knowledge begins with self-knowledge. This common perspective is almost always universalized. Its emphasis is not upon the individual as a particular European or American, but upon the human as universal, freed from the accidents of times, space, birth, and talent. Thus, for Emerson, the "American Scholar" turns out to be simply "Man Thinking". While, for Whitman, the "Song of Myself" merges imperceptibly into a song of all the "children of Adam" where "every atom belonging to me as good belongs to you". Also common to all the five writers is the belief that individual virtue and happiness depend upon self-realization, which, in turn, depends upon the harmonious reconciliation of two universal psychological tendencies. First, the self-asserting impulse of the individual to withdraw, to remain unique and separate, and to be responsible only to himself or herself. Second, the self-transcending impulse of the individual to embrace the whole world in the experience of a single moment and to know and become one with that world. These conflicting impulses can be seen in the democratic ethic. Democracy advocates individualism, the preservation of the individual's freedom and self-expression. But the democratic self is torn between the duty to self, which is implied by the concept of liberty, and the duty to society, which is implied by the concepts of equality and fraternity. A third assumption common to the five writers is that intuition and imagination offer a surer road to truth than does abstract logic or scientific method. It is illustrated by their emphasis upon introspection——their belief that the clue to external nature is to be found in the inner world of individual psychology——and by their interpretation of experience as, in essence, symbolic. Both these stresses presume an organic relationship between the self and the cosmos of which only intuition and imagination can properly take account. These writers' faith in the imagination and in themselves as practitioners of imagination led them to conceive of the writer as a seer and enabled them to achieve supreme confidence in their own moral and metaphysical insights.

单选题One in three Americans said that money was a crucial factor in their decision to work for pay (or have a spouse work) rather than stay home to raise the children, with Baby Boomer women most likely to have made that choice. Forty-five percent of Baby Boomer women—compared with just 32 percent of those 55 and over—said they went to work. "Baby Boomer women, especially the older ones, grew up expecting to replicate the pattern of their mothers' lives," suggests Hochschild. "But then the bills started coming in and more job opportunities opened up, and these women moved into a life they hadn't anticipated." Money played a great role in marriage—even an unhappy one. Approximately 18 percent of all those interviewed said they stayed married because they lacked money to get a divorce, while less than 8 percent said that financial strain in their marriage has caused them to divorce. Lack of money also influenced education choices. Nearly one in four Americans has postponed or decided not to attend college because of financial pressures. Even with the sustained prosperity of the past eight years, Gen-Xers were most likely to have altered their college plans. A 39-year-old Hispanic billing clerk in New York spoke about how the need for money limited her teenager son's ability to take part in extracurricular activities that could increase his chances of getting into college. "Since age 14, my son's been working, and I think he is a superb person. Not having a lot of money has made him realize what work is all about. On the other hand, he was elected to go to a youth leadership conference in Washington, and I can't send him because I don't have the money. Lack of money takes away opportunities he otherwise could have had." On the question of what money can and can't buy, a large majority of Americans said that money could buy "freedom to live as you choose", "excitement in life", and "less stress". In a number of follow-up interviews, many people commented that having extra money would immediately alleviate one source of profound stress—the need to work overtime. Those with college and graduate degrees were far more likely to believe that money can buy freedom, perhaps because better-educated people already have a wider array of choices. College educated professionals, for instance, were much more likely to consider wealth a way of financing travel, starting a business of their own, or funding charitable works in their communities. A 55-year-old Hispanic woman in Los Angeles with a graduate degree and an income of more than $90,000 described a midlife career switch. After resigning from a high-level, high paying— but extremely stressful—civil service job, she became a florist. "After I started tearing my hair out," she said, "I decided to go into business for myself—flowers don't talk back." Can money buy peace of mind? Fifty-two percent of Americans said no. "It all depends on what 'peace' means to you," observed a businesswoman in California who is nearing 60 and would like to retire at 62 and go back to college. "For my husband, peace of mind means working as long as he can and collecting the biggest possible pension. For me, it means knowing I've worked long enough so that I can afford to go after an old dream. I guess you should say that my peace of mind is his worry./
