One idea is a platform capable of flying vertically and hovering in the air like a helicopter. The platform would rise up and down alongside a skyscraper and pick up people trapped in high stories. The idea for the vertical takeoff platform was hatched more than ten years ago by a Russian aerospace engineer, David Metreveli, who has since moved to Israel. Metreveli’s dedsign, called the Eagle, calls for two jet engines that turn four large horizontal propellers. The spinning of the propellers generates the necessary lift, or upward force, to raise the platform. The more power is supplied to the propellers, the higher the platform rises. Moving the platform sideways involves applying differing amounts of power to each propeller. Helicopters are now used in some cases to get people out of buming buildings, Escape baskets slung from them dangle beside the building for people to climb into. Unfortunately, the baskets cannot reach every floor of a building because the ropes from which they hang become unstable beyond a certain length. So far, Metreveli has built a small-scale model of the Eagle to test his idea. In the wake of September 11, he has been able to secure enough funding to start building a larger, 4-meter by 4-meter prototype, which he calls the Eaglet. In the third paragraph, the word helicopter refers to the Eagle.
第三篇 Computers in Cars You’re far from home on a lonely road. Shadowy forests stretch away on both sides. A thick mist (雾) makes it difficult to see far beyond your car’s windshield (挡风玻璃). "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 exists. Several experimental models are being tested by General Motors, Ford, Chrysler, and several foreign car markets. These computers vary in details. But they all contain series of maps on Vediodiscs 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 a 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. A navigation 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) routes. Most cars nowadays also contain computers that help cars run more effic!ently. Microprocessors (微处理机的) control certain engine functions by regulating the mixing of fuel. Data on car speed, oil pressure, revolutions per minute, engine temperature, and fuel level’ can be displayed as digital data (numbers) or warming lights. Some auto designers suggest that a central computer display can be used to clearly present such timely information as car speed and fuel level. Warning lights would indicate a drop in oil pressure or a sudden rise in engine temperature. To get more information on these conditions, the driver would 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. The navigation computers have one thing in common: they all ______.
