第4题：Large, multinational corporations may be the companies whose ups and downs seize headlines.But to a far greater extent than mostAmericans realize, the economy’s vitality depends on the fortunes of tiny shops and restaurants, neighborhood services and factories. Small businesses, defined as those with fewer than 100 workers, now employ nearly 60 percent of the work force and are expected to generate half of all new jobs between now and the year 2000. Some 1.2 million small firms have opened their doors over the past six years of economic growth, and 1989 will see an additional 200,000 entrepreneurs striking off on their own. Too many of these pioneers, however, will blaze ahead unprepareD、Idealists will overestimate the clamor for their products or fail to factor in the competition. Nearly everyone will underestimate, often fatally, the capital that success requires. Midcareer executives, forced by a takeover or a restructuring to quit the corporation and find another way to support themselves, may savor the idea of being their own boss but may forget that entrepreneurs must also, at least for a while, be bookkeeper and receptionist, too.According to SmallBusinessAdministration data,24 of every 100 businesses starting out today are likely to have disappeared in two years, and 27 more will have shut their doors four years from now.By 1995, more than 60 of those 100 start-ups will have foldeD、 A、new study of 3,000 small businesses, sponsored byAmericanExpress and the National Federation of IndependentBusiness, suggests slightly better odds: Three years after start-up, 77 percent of the companies surveyed were still alive. Most credited their success in large part to having picked a business they already were comfortable in.Eighty percent had worked with the same product or service in their last jobs. Thinking through an enterprise before the launch is obviously critical.But many entrepreneurs forget that a firm’s health in its infancy may be little indication of how well it will age. You must tenderly monitor its pulse. In their zeal to expand, small-business owners often ignore early warning signs of a stagnant market or of decaying profitability. They hopefully pour more and more money into the enterprise, preferring not to acknowledge eroding profit margins that mean the market for their ingenious service or product has evaporated, or that they must cut the payroll or vacate their lavish offices. Only when the financial well runs dry do they see the seriousness of the illness, and by then the patient is usually too far gone to save. Frequent checks of your firm’ s vital signs will also guide you to a sensible rate of growth. To snatch opportunity, you must spot the signals that it is time to conquer new markets, add products or perhaps franchise your hot ide A、 In a recent research, after three years, ______small enterprises will be alive among 3,000 small businesses. A、more than 60 B．more than 51 C．more than 2,310 D．more than 2,400

第7题：That Louise Nevelson is believed by many critics to be the greatest twentieth- century sculptor is all the more remarkable because the greatest resistance to women artists has been, until recently, in the field of sculpture. Since Neolithic times, sculpture has been considered the prerogative of men, partly, perhaps, for purely physical reasons: it was erroneously assumed that women were not suited for the hard manual labor required in sculpting stone, carving wood, or working in metal. (47) It has been only during the twentieth century that women sculptors have been recognized as major artists, and it has been in the United States, especially since the decades of the fifties and sixties, that women sculptors have shown the greatest originality and creative power. Their rise to prominence parallels the development of sculpture itself in the United States : (48) while there had been a few talented sculptors in the United States before the 1940’s, it was only after 1945--when New York was rapidly becoming the art capital of the world--that major sculpture was produced in the United States. Some of the best was the work of women. By far the most outstanding of these women is Louise Nevelson, who in the eyes of many critics is the most original female artist alive today. One famous and influential critic, Hilton Kramer, said of her work, "For myself, I think Ms. Nevelson succeeds where the painters often fail. " Her works have been compared to theCubist constructions of Picasso, the Surrealistic objects of Miro, and the Merzbau of Schwitters. (49) Nevelson would be the first to admit that she has been influenced by all of these, as well as byAfrican sculpture, and by NativeAmerican and pre-Columbian art, but she has absorbed all these influences and still created a distinctive art that expresses the urban landscape and the aesthetic sensibility of the twentieth century. Nevelson says, "I have always wanted to show the world that art is everywhere, except that it has to pass through a creative minD、" (50) Using mostly discarded wooden objects like broken pieces of furniture and abandoned architectural ornaments, all of which she has hoarded for years, she assembles architectural constructions of great beauty and power.Creating very freely with no sketches, she glues and nails objects together, paints them black, or more rarely white or gold, and places them in boxes. These assemblages, walls, even entire environments create a mysterious, almost awe-inspiring atmosphere.Although she has denied any symbolic or religious intent in her works, their three-dimensional grandeur and even their titles, such as SkyCathedral and NightCathedral, suggest such connotations. In some ways, her most ambitious works are closer to architecture than to traditional sculpture, but then neither Louise Nevelson nor her art fits into any neat category.
