"Can this be route 90A？" you wonder. If it is, you should be near a town. Yet there's no hint of one. Night is closing in. And you're low on gasoline.
This is a situation where an in-car computer that can navigate would be a big help. A．car computer that navigates？ Yes! Such computers exist.

But they all contain series of maps on videodiscs or videotapes. For example, one computer system contains 13,300 maps covering the continental US.
Before starting out on a trip, a driver can type in the code for the region he or she plans to drive through. The computer then shows a map of that region. At the same time, a tiny radio receiver linked to the computer goes to work. It picks up signals from navigation satellites such as the NAVSTAR network. Using these signals, the computer shows the car's position at all times and displays this position on the map. The computer can also calculate and display the best route to follow.
Anavigation computer may also receive and use data about road construction, weather conditions, and traffic jams. This information would be displayed to the driver and the computer would also use the information to work out alternate (交替的) roules.

Data on car speed, oil pressure, revolutions per minute, engine temperature, and fuel level can be displayed as digital data (numbers) or warning lights.
Some auto designers suggest that a central computer display be used to clearly present such timely information as car speed and fuel level.

Our lives are a【C8】______of our decisions--whether in business or 15ersonal【C9】______. And in every decision, there comes a crucial point when you must make up your mind. Deciding too quickly can bring【C10】______consequences;【C11】______too long can mean missed opportunities.

In July 1862, in the【C13】______of the Civil War, Abraham Lincoln【C14】______his Cabinet members to the White House to【C15】______them of a decision he had made. The president read aloud to them the Emancipation Proclamation,【C16】______for freeing slaves in the Southern states at war with the Union. When he finished, the Cabinet members were silent. It was a【C17】______idea for the time and bound to【C18】______controversy even in the North.
Then Secretary of State, William Seward spoke up. The Confederates had recently routed the Union Army, and Lincoln's proclamation might be interpreted as a【C19】______move. Wily not wait until the picture was brighter？ Lincoln welcomed his advice and delayed the proclamation until September, when the battle of Antietam had stopped a confederate advance. The decision was then【C20】______received by supporters of the Union.

Feelings aren't usually associated with inanimate machines, but Rosalind Picard, a professor of computer technology at MIT, believes emotion may be just the thing computers need to work effectively. Computers need artificial emotion to understand their human users better and to achieve self-analysis and self-improvement.
The more scientists study the "wetware" model for computing—the human brain and nervous system—the more they conclude that emotions are a part of intelligence, not separate from it. Emotions are among the tools that we use to process the tremendous amount of stimuli in our environment. They also pay a role in human learning and decision making. Feeling bad about a wrong decision, for instance, focuses attention on avoiding future error. A feeling of pleasure, on the other hand, positively reinforces an experience.
"If we want computers to be genuinely intelligent, to adapt to us, and to interact naturally with us, then they will need the ability to recognize and express emotions, to have emotions, and to have what has come to be called 'emotional intelligence,'" Picard says.
One way that emotions can help computers, she suggests, is by helping keep them from crashing. Today's computers produce error messages, but they do not have a "gut feeling" of knowing when something is wrong or doesn't make sense. A healthy fear of death could motivate a computer to stop trouble as soon as it starts. On the other hand, self-preservation would need to be subordinate to service to humans. It was fear of its own death that prompted HAL, the fictional computer in the film 2002: A Space Odyssey, to kill most of its human associates.
Similarly, computers that could "read" their users would accumulate a store of highly personal information about us—not just what we said and did, but what we likely thought and felt.
"Emotions not only contribute to a richer quality of interaction, but they directly impact a person's ability to interact in an intelligent way," Picard says. "Emotional skills, especially the ability to recognize and express emotions, are essential for natural communication with humans."
In the future computers will tend to be made ______.
A．fictional
B．humanized
C．economical
D．operational
