2、ries of the twentieth century. There are presently 500 million cars on earth, or one car for every ten people. Sales of the automobile industry stand at about a trillion dollars, making it the worlds biggest manufacturing industry.汽车工业是20世纪最赚钱、最有影响力的产业之一。目前世界上有5亿辆车，或者说每10人就有1辆车。汽车工业的销售额达一万亿美元左右，从而成为
3、世界上最大的制造业。3 The car, and the roads it travels on, will be revolutionized in the twenty-first century. The key to tomorrows “smart cars“ will be sensors. “Well see vehicles and roads that see and hear and feel and smell and talk and act,“ predicts Bill Spreitzer, technical director of General Motors
4、Corporations ITS program, which is designing the smart car and road of the future.汽车及其行驶的道路，将在21世纪发生重大变革。未来“智能汽车” 的关键在于传感器。 “我们会见到能看、能听、有知觉、具嗅觉、会说话并能采取行动的车辆与道路， ”正在设计未来智能汽车和智能道路的通用汽车公司ITS项目的技术主任比尔斯普雷扎预言道。4 Approximately 40,000 people are killed each year in the United States in traffic accidents. Th
5、e number of people that are killed or badly injured in car accidents is so vast that we dont even bother to mention them in the newspapers anymore. Fully half of these fatalities come from drunk drivers, and many others from carelessness. A smart car could eliminate most of these car accidents. It c
6、an sense if a driver is drunk via electronic sensors that can pick up alcohol vapor in the air, and refuse to start up the engine. The car could also alert the police and provide its precise location if it is stolen.美国每年有大约4万人死于交通事故。在汽车事故中死亡或严重受伤的人数太多，我们已经不屑在报纸上提及。这些死亡的人中至少有半数是酒后开车者造成的，另有许多死亡事故是驾驶员不
7、小心所导致。智能汽车能消除绝大多数这类汽车事故。它能通过会感测空气中的酒精雾气的电子传感器检测开车者是否喝醉酒，并拒绝启动引擎。这种车还能在遇窃后通报警方，告知车辆的确切地点。5 Smart cars have already been built which can monitor ones driving and the driving conditions nearby. Small radars hidden in the bumpers can scan for nearby cars. Should you make a serious driving mistake (e.g.,
8、 change lanes when there is a car in your “blind spot“) the computer would sound an immediate warning. 能监控行车过程以及周围行车状况的智能汽车已经建造出来。藏在保险杠里的微型雷达能对周围的汽车作扫描。如果你发生重大行车失误（如变道时有车辆你“盲点”内） ，计算机立即会发出警报。6 At the MIT Media Lab, a prototype is already being built which will determine how sleepy you are as you dri
9、ve, which is especially important for long-distance truck drivers. The monotonous, almost hypnotic process of staring at the center divider for long hours is a grossly underestimated, life-threatening hazard. To eliminate this, a tiny camera hidden in the dashboard can be trained on a drivers face a
10、nd eyes. If the drivers eyelids close for a certain length of time and his or her driving becomes erratic, a computer in the dashboard could alert the driver.在麻省理工学院媒介实验室，业已制造出能测知你行车时有多少睡意的样车，这对长途卡车司机意义尤其重要。一连数小时注视着中夹分道线这样一个单调、几乎能催眠的过程是被严重低估的威胁生命的重大隐患。为消除这一隐患，藏在仪表板里的一架微型相机可对准开车者的脸部及眼睛。如果司机的眼帘合上一定时间，
11、行车变得不稳，仪表板里的计算机就会向司机发出警报。7 Two of the most frustrating things about driving a car are getting lost and getting stuck in traffic. While the computer revolution is unlikely to cure these problems, it will have a positive impact. Sensors in your car tuned to radio signals from orbiting satellites can l
12、ocate your car precisely at any moment and warn of traffic jams. We already have twenty-four Navstar satellites orbiting the earth, making up what is called the Global Positioning System. They make it possible to determine your location on the earth to within about a hundred feet. At any given time,
13、 there are several GPS satellites orbiting overhead at a distance of about 11,000 miles. Each satellite contains four “atomic clocks,“ which vibrate at a precise frequency, according to the laws of the quantum theory.开车最头疼的两大麻烦是迷路和交通堵塞。虽然计算机革命不可能彻底解决这两个问题，但却会带来积极的影响。你汽车上与绕轨道运行的卫星发出的无线电信号调谐的传感器能随时精确地
14、确定你汽车的方位，并告知交通阻塞情况。我们已经有24颗环绕地球运行的导航卫星，组成了人们所说的全球卫星定位系统。通过这些卫星我们有可能以小于100英尺的误差确定你在地球上的方位。在任何一个特定时间，总有若干颗全球定位系统的卫星在11000英里的高空绕地球运行。每颗卫星都装有4个“原子钟” ，它们根据量子理论法则，以精确的频率振动。8 As a satellite passes overhead, it sends out a radio signal that can be detected by a receiver in a cars computer. The cars computer
15、 can then calculate how far the satellite is by measuring how long it took for the signal to arrive. Since the speed of light is well known, any delay in receiving the satellites signal can be converted into a distance.卫星从高空经过时发出能被汽车上计算机里的接收器辨认的无线电信号。汽车上的计算机就会根据信号传来所花的时间计算出卫星有多远。由于光速为人熟知，接收卫星信号时的任何时
16、间迟缓都能折算出距离的远近。9 In Japan there are already over a million cars with some type of navigational capability. (Some of them locate a cars position by correlating the rotations in the steering wheel to its position on a map.)在日本，具有某种导航能力的汽车已有一百万辆之多。 （有些导航装置通过将方向盘的转动与汽车在地图上的位置并置来测定汽车的方位。 ）10 With the pric

Blind individuals could use GPS sensors in walking sticks, airplanes co
18、uld land by remote control, hikers will be able to locate their position in the woods - the list of potential uses is endless.随着微芯片价格的大幅度下降，未来对全球卫星定位系统的应用几乎是无限的。“制造这一商品的工业定会飞速发展， ”生产导航系统的麦哲伦航仪公司的兰迪霍夫曼说。盲人可以在手杖里装配全球卫星定位系统传感器，飞机可以通过遥控着陆，徒步旅行者可以测定自己在林中的方位其潜在的应用范围是无止境的。11 GPS is actually but part of a l
19、arger movement, called “telematics,“ which will eventually attempt to put smart cars on smart highways. Prototypes of such highways already exist in Europe, and experiments are being made in California to mount computer chips, sensors, and radio transmitters on highways to alert cars to traffic jams
20、 and obstructions.全球卫星定位系统其实只是叫做“远程信息学” 的这一更大行动的一部分，这一行动最终将把智能汽车送上智能高速公路。这种高速公路的样品已经在欧洲问世，加州也在进行试验，在高速公路上安装计算机芯片、传感器和无线电发射机，以便向汽车报告交通拥挤堵塞情况。12 On an eight-mile stretch of Interstate 15 ten miles north of San Diego, traffic engineers are installing an MIT-designed system which will introduce the “aut
21、omated driver.“ The plan calls for computers, aided by thousands of three-inch magnetic spikes buried in the highway, to take complete control of the driving of cars on heavily trafficked roads. Cars will be bunched into groups of ten to twelve vehicles, only six feet apart, traveling in unison, and
22、 controlled by computer.在圣迭戈以北10英里的15号州际公路一段8英里长的路面上，交通工程师正在安装一个由麻省理工学院设计的引进“自动司机” 的系统。这一计划要求计算机在公路上埋设的数千个3英寸长的磁钉的协助下，在车辆极多的路段完全控制车辆的运行。车辆会编成10辆或12辆一组，车距仅6英尺，在计算机的控制下一齐行驶。13 Promoters of this computerized highway have great hopes for its future. By 2010, telematics may well be incorporated into one
23、of the major highways in the United States. If successful, by 2020, as the price of microchips drops to below a penny a piece, telematics could be adopted in thousands of miles of highways in the United States. This could prove to be an environmental boon as well, saving fuel, reducing traffic jams,
24、 decreasing air pollution, and serving as an alternative to highway expansion.这种计算机化的公路的倡导者对其未来的应用充满希望。到2010年，远程信息技术很可能应用于美国的一条主要公路。如果成功的话，到2020年，当微芯片的价格降到一片一美分以下时，远程信息技术就会应用在美国成千上万英里的公路上。这对环保也会很有利，能节省燃油，减轻交通阻塞，减少空气污染，还可用作公路扩建的替代办法。Vocabulary1) Before Anglo-American westward expansion, North America
