　　Navigation computers, now sold by most car-makers, cost $2,000 and up. No surprise, then,that they are most often found in luxury cars, like Lexus, BMW and Audi. But it is a developingtechnology—meaning prices should eventually drop—and the market does seem to be growing.

　　Even at current prices, a navigation computer is impressive. It can guide you from point topoint in most major cities with precise turn-by-turn directions—spoken by a clear human-sounding voice, and written on a screen in front of the driver.

　　The computer works with an antenna ***天線*** that takes signals from no fewer than three of the24 global positioning system ***GPS*** satellites. By measuring the time required for a signal totravel between the satellites and the antenna, the car’s location can be pinned down within 100meters.

　　The satellite signals, along with inputs on speed from a wheel-speed sensor and direction froma meter, determine the car’s position even as it moves. This information is combined with amap database. Streets, landmarks and points of interest are included.

　　Most systems are basically identical. The differences come in hardware—the way the computeraccepts the driver’s request for directions and the way it presents the driving instructions. Onmost systems, a driver enters a desired address, motorway junction or point of interest via atouch screen or disc. But the Lexus screen goes a step further: you can point to any spot onthe map screen and get directions to it.

　　BMW’s system offers a set of cross hairs ***瞄準器上的十字紋*** that can be moved across the map***you have several choices of map scale*** to pick a point you’d like to get to. Audi’s screen canbe switched to TV reception.

　　Even the voices that recite the directions can differ, with better systems like BMW’s andLexus’s having a wider vocabulary. The instructions are available in French, German, Spanish,Dutch and Italian, as well as English. The driver can also choose parameters for determining theroute: fastest, shortest or no freeways ***高速公路***, for example.

　　六級閱讀理解真題練習2

　　“The world’s environment is surprisingly healthy. Discuss.” If that were an examination topic,most students would tear it apart, offering a long list of complaints: from local smog ***煙霧*** toglobal climate change, from the felling ***砍伐*** of forests to the extinction of species. The listwould largely be accurate, the concern legitimate. Yet the students who should be given thehighest marks would actually be those who agreed with the statement. The surprise is howgood things are, not how bad.

　　After all, the world’s population has more than tripled during this century, and world outputhas risen hugely, so you would expect the earth itself to have been affected. Indeed, if peoplelived, consumed and produced things in the same way as they did in 1900 ***or 1950, or indeed1980***, the world by now would be a pretty disgusting place: smelly, dirty, toxic anddangerous.

　　But they don’t. The reasons why they don’t, and why the environment has not been mined,have to do with prices, technological innovation, social change and government regulation inresponse to popular pressure. That is why, today’s environmental problems in the poorcountries ought, in principle, to be solvable.

　　Raw materials have not run out, and show no sign of doing so. Logically, one day they planet is a finite place. Yet it is also very big, and man is very ingenious. What hashappened is that every time a material seems to be running short, the price has risen and, inresponse, people have looked for new sources of supply, tried to find ways to use less of thematerial, or looked for a new substitute. For this reason prices for energy and for minerals havefallen in real terms during the century. The same is true for food. Prices fluctuate, in responseto harvests, natural disasters and political instability; and when they rise, it takes some timebefore new sources of supply become available. But they always do, assisted by new farmingand crop technology. The long term trend has been downwards.

　　It is where prices and markets do not operate properly that this benign ***良性的*** trend beginsto stumble, and the genuine problems arise. Markets cannot always keep the environmenthealthy. If no one owns the resource concerned, no one has an interest in conserving it orfostering it: fish is the best example of this.
