Just as the trends of the 1980s were difficult to predict, so, too, are the forces that will drive the industry in the 1990s. But by looking at the trends of today, people are able to predict what the industry may look like in the new decade.
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

After an intense three-month heat wave, Indians in the north and east of the subcontinent were praying hard for rain. Their prayers were heard and answered in the form. of a curse. Violent downpours flooded much of the country, drowning more than 500 people and leaving thousands more homeless. Walls of water hit 26 cities and 2,500 villages, washing away bridges, submerging reads and railways in waist- deep torrents, cutting power lines and wiping out animals, crops and factories. In all, the storm destroyed more than $ 1 billion worth of property. The death toll in neighboring Bangladesh rose to nearly 300 since mid-June. More than 400 people died in Nepal and another 700 were missing.
The rains hit India hardest in Punjab (旁遮普邦), which was transformed into a wasteland of collapsed houses and dead cattle. In the village of Doomchheri, 40 km southwest of Chandigarh, Punjab's capital, floods rising to a height of 4m washed away 400 of the 700 homes and destroyed all the crops. Jaswant Kaur and her family of five clung to trees when their mud hut collapsed. One cousin drowned; the other four swam to safety, reaching the second story of a neighbor's home. Wailed Jaswant:" What have we done to be cursed like this ？"
In the country the armed forces were mobilized to help. In Punjab 5,000 uniformed men used helicopters and assault boats to rescue victims isolated by flood, distribute food and medicine and, finally, remove the dead. Near the town of Patiala, 85 km south of Chandigarh, all 16 members of a rescue team drowned when their boat tipped over in 4m waves. One soldier named Sohan Singh could have survived, witnesses reported, but he ordered panic-stricken villagers to cling to him while he struggled toward safety. His body was found four days later, along with two dead villagers whose arms were wrapped around one of his legs.
Which of the following is the best title for the passage？
A．Curse of Heaven
B．Floods Hit India
C．Floods Claim Hundreds of Lives
D．A Terrible Disaster
