Hardware will become a commodity while software and service will account for a greater share of computer companies' revenue, say market watchers. And growth in sales of special systems will come to a halt in the '90s. As more computer systems are based on such emerging standards as the Unix operating system, customers can pick and choose the best components from different vendors rather than relying on one supplier for complete computer systems. That will accelerate demand for service--rather than products--from vendors. It's the service, the support and the software that add all the value. The move to distributed computers linked by local area networks is increasingly becoming an alternative to centralized computers. A survey of 50 Fortune 1000 companies found that 72 per cent were replacing their minicomputers with personal computer networks. Some trends in the peripherals (外部设备) arena in the next decade are obvious--smaller, quicker, more features. But manufacturers of monitors, printers and disk drives will be looking beyond the computer industry toward future markets that hold vast sales potential. The automobile industry, for example, holds promise for peripherals vendors. It's very likely in the next five to ten years we'll see vehicles targeted at business executives with printers and fax (传真) machine capabilities built in. The main idea of the passage is about ______. A．the trends of the 1990s in computer industry B．the accelerating demands for software and service C．computers industry's close link with auto-industry D．the trends in the peripherals arena in the next decade

Chief economic advisor to the president, Walter Abel, told a news conference that in- creased foreign competition, rising prices for raw materials, and high interest rates would hold economic growth to less than 3% for the year with inflation rising above 7%. Abel said, however, that administration programs to restructure the economy would begin bearing fruit toward the end of the year and that growth in the gross national product would turn sharply upwards in the last quarter. He also said that the administration of President Arling was determined to increase investment in high technology industries, upgrade aging plant equipment in heavy industry, and encourage workers to increase productivity. Abel admitted that high interest rates threatened the strategy, but warned that any action to artificially lower interest rates risked fueling even greater inflation. "We are still recovering from the recession caused by the previous administration and attempts to force the pace of recovery could be dangerous," he said. The forecast for the next six months is encouraging. A．Right B．Wrong C．Doesn't say
