Computers, which once only remembered data, will make more decisions. Machines that today tell doctors what symptoms the patients have may soon be recommending whether or not to perform. surgery as well. Others will design new buildings after questioning buyers about their preferences. Increasingly, human thought processes and even values are being programmed into computers, according to Earl Joseph, president of a consulting firm. "Imagine machines which are smarter and more intelligent than humans and, with their embedded(植入的) initiative, can't wait to tell you about it," he says. In everyday life, the future will mean talking directly to computers without pushing buttons. Just tell a toaster, stove or other kitchen device what to do, and it will hear the message. The oven may even decide itself how long to cook the roast. Tell the television, "I want to watch Channel 12 at 8 p.m., but store the show for next week," and the job will be done. The computer will talk back, too. Already some soft-drink machines complain loudly if you don't deposit enough cash. At home, a bedside machine may someday tell you, "You forgot to turn off the basement light." Away from home, the automobile of the future will think for itself. Scientists predict that drivers will feed destinations into a computer that will then explain what route to take and even tell where parking spaces are available. A city's traffic-control system might instruct the car's computer how fast to go in heavy traffic and whether to change lanes. This passage mainly discusses ______. A．the history of computers B．the different functions of computers C．the computer in the 21st century D．scientific breakthroughs in the 21st century

&8226;Which section (A, B, C, or D) does each statement 1--7 refer to？ &8226;For each statement 1--7, mark one letter (A, B, C, or D) on your Answer Sheet. &8226;You will need to use some of these letters more than once. A It's the space where commodities traders turn into couch potatoes and kids spend every waking moment from the terrible twos to the terrifying teens. Whatever you want to call it--the living room, the family room, the playroom--it's now the most wired room in the house, even more so, surprisingly, than the home office. So it's about time you got some R&R (Rest and Relaxation) payback from all that technology. B Despite many changes in the past few decades, we're essentially doing the same things in the family room we've always done. These include watching TV and movies, listening to music, and communicating with friends. But now we've gone hi-tech. The capabilities and quality of the devices we use today have improved dramatically, and there's much more to come. Parts of your future living room are currently well-defined and developed, but hooking them all up into a cohesive whole is still like piecing together a jigsaw puzzle. C In recent years, TVs have become bigger and more beautiful. But we're still paying a high price for the size and beauty. Take, for example, Toshiba's 65-inch Theater Wide HD Projection TV, which is big enough to make you feel like you're really in a movie theater. As it costs almost $ 8, 500, you could practically hire some actors to perform. in your living room for less. But you're paying for the size and picture quality of a projection TV, as well as future-proofing support for digital High-Definition TV. D The great thing about life in the 21st century is how much easier when you get home. In Tokyo the folds at Panasonic have built a mockup of what they call "the house of the future". In the future, it's gonna be video mail and starts when you do a fingerprint analysis to let the computer know you're home. Sensors then note your presence, turn on the lights and set each room's temperature to your preference, or fire up the 500-channel, 50-inch plasma TV, which can store a hundred hours of TV programs in the main home computer. What we have done in the living room will be related closely to each other in the future.
