单选题Paragraph 1 Kodak"s decision to file for bankruptcy (破产) protection is a sad, though not unexpected, turning point for a leading American corporation that pioneered consumer photography and dominated the film market for decades, but ultimately failed to adapt to the digital revolution. Paragraph 2 Although many attribute Kodak"s downfall to "complacency (自满)," that explanation doesn"t acknowledge the lengths to which the company went to reinvent itself. Decades ago, Kodak anticipated that digital photography would overtake film-and in fact, Kodak invented the first digital camera in 1975—but in a fateful decision, the company chose to shelf its new discovery to focus on its traditional film business. Paragraph 3 It wasn"t that Kodak was blind to the future, said Rebecca Henderson, a professor at Harvard Business School, but rather that it failed to execute on a strategy to confront it. By the time the company realized its mistake, it was too late. Paragraph 4 Kodak is an example of a firm that was very much aware that they had to adapt, and spent a lot of money trying to do so, but ultimately failed. Large companies have a difficult time switching to new markets because there is a temptation to put existing assets into the new businesses. Paragraph 5 Although Kodak anticipated the inevitable rise of digital photography, its corporate (企业的)culture was too rooted in the successes of the past for it to make the clean break necessary to fully embrace the future. They were a company stuck in time. Their history was so important to them. Now their history has become a liability. Paragraph 6 Kodak"s downfall over the last several decades was dramatic. In 1976, the company commanded 90% of the market for photographic film and 85% of the market for cameras. But the 1980s brought new competition from Japanese film company Fuji Photo, which undermined Kodak by offering lower prices for film and photo supplies. Kodak"s decision not to pursue the role of official film for the 1984 Los Angeles Olympics was a major miscalculation. The bid went instead to Fuji, which exploited its sponsorship to win a permanent foothold in the marketplace.

单选题Is this any way to plan for retirement? After a week of huge swings, the Standard ＆ Poor's 500-stock index, a broad assess of the market, was modestly higher on Friday but still down for the week. On Monday, the market plunged; on Tuesday, it roared back, only to drop sharply again on Wednesday before soaring on Thursday. As The Times's Floyd Norris and Christine Hauser pointed out on Friday, never before in the history of the S. ＆ P. 500, which dates back to 1928, had there been four alternating days of losses and gains of more than 4 percent. There have only been two times since the Great Depression when the index has moved at least 4 percent in four straight trading sessions—in October 1987, when the market crashed, and in November 2008, during some of the darkest days of the financial crisis. Those are not exactly moments in stock market history that inspire investor confidence. For individual investors, whose ability to retire depends on stock investments in 401 (k) 's and other retirement plans, recent swoons (疲软) are yet another hit. If a worker had invested entirely in stocks, retirement might still be a very long way off. The results would be better if an investor had a retirement portfolio (投资组合) evenly divided between stocks and bonds—a 5.5 percent gain from the peak in 2007 to the close on Friday. For policy makers, the changeful week is yet another moment to reconsider the risks in 401 (k) 's and the need to make retirement savings safer. One of the thorniest problems is that even someone who steadily contributes to a 401 (k) and makes sensible investments can still end up with too little, depending solely on whether markets are up or down as retirement nears. There needs to be a way to ensure that a lifetime of savings cannot be undermined by forces beyond one's control. Alicia Munnell, director of the Center for Retirement Research at Boston College, has an idea that deserves more study and debate: a new type of savings account—in addition to Social Security and 401 (k)'s—that would spread the risks among workers, retirees and government. One thing is sure. Having each individual bear all of the investing risk is not the road to a secure retirement.
