问题    Expanded use of computer technology, development of stronger and lighter materials, and research on pollution control will produce better, "smarter" automobiles. In the 1980s the notion that a car would
"talk" to its driver was science fiction; by the 1990s it had become reality.
   Onboard navigation was one of the new automotive technologies in the 1990s. By using the satellite-aided global positioning system (GPS), a computer in the automobile can pinpoint the vehicle’s location within a few feet. The onboard navigation system uses an electronic compass, digitized maps, and a display screen showing where the vehicle is relative to the destination the driver wants to reach. After being told the destination, the computer locates it and directs the driver to it, offering alternative routes if needed.
   Some cars now come equipped with GPS locator beacons, enabling a GPS system operator to locate the vehicle, map its location and, if necessary, direct repair or emergency workers to the scene.
   Cars equipped with computers and cellular (蜂窝) telephones can link to the Internet to obtain constantly updated traffic reports, weather information, route directions, and other data. Future built-in computer systems may be used to automatically get business information over the Internet and manage personal affairs while the vehicle’s owner is driving.

选项 A、New Technology in Automobile
B、What is the GPS
C、Automobile
D、GPS Automobile

答案A

解析 从文章整体来看,第二段讲的是“Onboard navigation”技术在“automobile”中的应用,第三段讲的是“GPS”系统技术在“automobile”中的应用,第四段讲的是计算机和蜂窝电话在“automobile”中的应用,而文章开头第一句话“Expanded use of computer technology, development of stronger and lighter materials, and researd, on pollution control will produce better smarter automobiles.”统领全文。因此文章的标A项合适。
