Computers in Cars
You're far from home on alonely road. Shadowy forests stretch away on both sides. athickmist (雾) makes it difficult to see far beyond your car's windshield (挡风玻璃).
"Can this B.e route 90A?" you wonder. If it is, you should be near atown. Yet there's nohint of one. Night is closing in. And you're low on gasoline.
This is asituation where an in-car computer that can navigate would be abig help.
A car computer that navigates? Yes! Such computers exist. Several experimental models arebeing tested by General Motors, Ford, Chrysler, and several foreign car makers. These computersvary in detail. but they all contain series of maps on videodiscs or videotapes. For example, onecomputer system contains 13,300 maps covering the continental US.
before starting out on atrip, er can type in the code for the region he or she plans todrive through. The computer then shows amap of that region. At the same time, atiny radio re-ceiver linked to the computer goes to work. It picks up signals from navigation satellites such asthe NAVSTAR network. Using these signals, the computer shows the car's position at all timesand displays this position on the map. The computer can also calculate and display the best routeto follow.
Anavigation computer may also receive and use dataabout road construction, weather condi-tions, and trafficjams. This information would be displayed to the driver and the computer wouldalso use the information to work out alternate (交替的 ) routes.
Most cars nowadays also contain computers that help cars run more efficiently. Microproces-sors (微处理的) control certain engine functions B.y regulating the mixing of fuel. Dataon carspeed, oil pressure, revolutions per minute, engine temperature, and fuel level can be displayedas digital data(numbers) or warning lights.
Some auto designers suggest that acentral computer display be used to clearly present suchtimely information as car speed and fuel level. Warning lights would indicate adrop in oil pres-sure or asudden rise in engine temperature. To get more information on these conditions, thedriver could call it up on the computer display screen. When needed, the computer could be"asked" to provide navigation aid or information about the car's condition.
by describing atypical situation of alost driver on the road, the author intends to__________.
us believe how complex the highway computer network is
us know how in-car computers are linked to road signs
us how helpful anavigation computer can be
us that NAVSTAR has come into use
参考答案：C
参考解析：文章第二段描述了一位司机迷路的情况，紧接着第三段讲到，当汽车上装载了计算机导航系统后，会给司机到来很大的方便。很明显，答案为选项C。
The word "navigate" in Paragraph 3 means__________.
A."help one control the traffic"
B."help one find one's way"
C."give aship correct information about its course"

参考答案：A
参考解析： 本题是根据第四段中间这两句话出的问题“These computers vary in theyall contain series of maps on videodiscs or videotapes.”所有(车载)计算机导航系统都含有电子地图，即保存在视盘或录像带上的地图(series of maps on videodiscs or video-tapes)，所以A为正确答案。
Without signals from navigation satellites, the in-car computer__________.
d still be able to locate the. car's position at all times
d fail to locate the car's position
d still work out the best route to follow
d seek help from the radio receiver linked to it
参考答案：B
参考解析： 本题问的是当车载计算机收不到来自导航卫星的信号时会出现什么情况。根据常识可以判断，计算机无法确定汽车的位置。此题可以通过第五段中的“Using these sig-nals，the computer shows the car's position at all times and displays this position on themap.”推断出来，本题是此句意思的`反说。

icting acar crash on the road.
ing information about road construction, weather conditions, and trafficjams.
ing the car's position at all times and displaying it on the map.
