单选题Americans are often contrasted with the rest of the world in terms of material possessions. We are accused of being materialistic, gadget crazy. And, as a matter of fact, we have developed material things for some very interesting reasons. Lacking a fixed class system and having all extremely mobile population, Americans have become highly sensitive to how others make use of material possessions. We use everything from clothes to houses as a highly evolved and complex means of ascertaining each other's status. Ours is a rapidly shifting system in which both styles and people move up or down. For example: The Cadillac (卡迪拉克) ad men feel that not only is it natural but quite insightful of them to show a picture of a Cadillac and a well-turned out gentleman in his early fifties opening the door. The caption (标题) underneath reads, "You already know a great deal about this man. " Following this same pattern, the head of a big union spends an excess of $100, 000 furnishing his office so that the president of United States Steel cannot look down on him. Good materials, large space, and the proper surroundings signify that the people who occupy the premises (建筑物及其周围所属土地) are solid citizens, that they are dependable and successful. The French, English, and the Germans have entirely different ways of using their material possessions. What stands for the height of dependability and respectability with the English would be old-fashioned and backward to us. The Japanese take pride in often inexpensive but tasteful arrangements that are used to produce the proper emotional setting. Middle East businessmen look for something else-family, connections, friendship. They do not use the furnishings of their office as part of their status system; nor do they expect to impress a client by these means or to fool a banker into lending more money than he should. They like good things, too, but feel that they, as persons, should be known and not judged solely by what the public sees. One of the most common criticisms of American relations abroad, both commercial and governmental, is that we usually think in terms of material things. "Money talks," says the American, who goes on talking the language of money abroad, in the belief that money talks the same language all over the world. A common practice in the United States is to try to buy loyalty with high salaries. In foreign countries, this maneuver almost never works, for money and material possessions stand for something different there from they do in America.

单选题Who to believe? Nokia or Ericsson? IBM or Sun Microsystems? Microsoft or Siebel? Rarely have the fortunes of technology companies appeared to differ so widely. Nokia, the world's largest maker of mobile phones, this week reported better-than-expected sales for the latest quarter. holding out the prospect that its market share would soon reach new highs. By contrast, Ericsson, a rival, was full of gloom. Reporting bigger losses than expected, the company said that sales of its mobile phones were likely to tumble by 20% this year. Motorola, another maker of mobile phones, is in a similar boat. On October 15th, the company reported a return to profit in its most recent period after a run of losses, but lowered its forecasts for the rest of the year and for 2003. Demand in wireless, broadband and semiconductors continued to slow, said the company. Unimpressed, investors marked down Motorola's shares to a ten-year low. The pattern of haves and have-nots is repeated in software too. While Microsoft was in chipper mood this week—revelling in a 26% increase in sales and a doubling of its profits after tax for the quarter to the end of September—Siebel Systems and PeopleSoft, two of America's leading suppliers of business software, were down in the dumps. While PeopleSoft managed a modest profit, Siebel reported a loss for the last quarter and said it expected the present quarter to be equally tough. Despite (or because of) their contrasting fortunes, Microsoft and Siebel announced a joint marketing deal on October 21st: Microsoft is to sell Siebel's customer-management software through. NET, its web-services product. Why are some companies doing better than others? One reason is that, now more than ever. those that are competitive seem to be punishing those that are not. Nokia has stretched its lead over Ericsson which, in addition to lower sales of mobile phones, has suffered from the severe fall in demand for telecoms infrastructure, its biggest business. There was. however, some good news for Ericsson's shares on October 18th, when the company said that the infrastructure unit came close to breaking even in the most recent quarter. Cost-cutting has also helped SAP, Europe's largest developer of business software, has reduced its expenses by 8%. As a result, its margins have improved a lot compared with those of its competitors. Microsoft has employed different tactics. It has capitalized on customers' fears that the cost of upgrading their software, such a s the company's Windows XP operating system, could climb. Many have rushed to buy now in case prices rise. In tune with the times, Microsoi't is also keen to demonstrate how its products can save its customers money. Understandably, this is winning its sales.
