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 developing technology-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 to point 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 that takes signals from no fewer than three or the 24, global positioning system satellites. By measuring the time required for a signal to travel between the satellites and the antenna. the cars location can be pinned down within l00 meters.
The satellite signals. along with inputs on speed from a wheel-speed sensor and direction from a meter, determine the car s position even as it moves. This information is combined with a map database. Streets, landmarks and points of interest are included.
Most systems are basically identical. The differences come in hardware-the way the computer accepts the drivers request for directions and the way it presents the driving instructions. On most systems, a driver enters a desired address, motorway junction or point of interest via a touch screen or disc. But the Lexus screen goes a step further: you can point to any spot on the map screen and get directions to it.
BMWs system offers a set of cross hairs(瞄準器上的的十字紋)that can be moved across the map to pick a point youd like to get to. Audis screen can be switched to TV reception.
Even the voices that recite the directions can differ, with better systems like BMWs and Lexuss 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 the route: fastest, shortest or no freeways, for example.
參考譯文
現在大多數汽車制造商出售的導航電腦價值都在2000美元或以上，因此它們大多用于一些豪華車內，如凌志，寶馬和奧迪，也是不足為奇的事。但它是一種發展中的技術 這意味著價格最終將下降 市場看來定將擴大。
即使就當前的價格而吉，導航電腦也足以令人動心。它通過精確的轉彎方向提示指引你在大多數重要城市里由此地去彼地。這些指示可以模擬清晰的真人發音，并書寫在駕駛者面前的屏幕上。
該電腦通過一根天線工作。這根無線至少能夠接收到24家全球定位衛星中的3家。通過計算衛星與天線之間信號傳播所需的時間，汽車的位置可被確定在lOO米的誤差范圍之內。
衛星信號，連同車速傳感器提供的車速數據和定向儀提供的方向一起確定出車子的位置，哪怕它處于移動當中。這些信息同一個地圖數據庫相結合，街道、路標或名勝之地都被包括在該數據庫之中。
/大多數導航系統基本都是相同的。區別之處在于硬件的不同，即電腦接受駕駛者詢問方向的指令，以及它提供指示的方式不同。在多數系統內，駕駛者通過觸摸屏或光盤輸入某個目的地地址，高速公路的交匯口，或名勝之處。但是凌志車的屏幕則更勝一籌：你能夠指向屏幕地圖的任何一點并獲得到達該地點的指示。
根據德國寶馬的系統設計，地圖上有一個可以移動的瞄準十字紋(有幾種地圖比例供選擇)。你想去哪里，就可以選定那里。而奧迪車的屏幕可以轉換為電視接受器。
像寶馬和凌志這樣的車，其更為出色的定位系統所儲存的詞匯量更大，甚至其復述指令的聲音也可以不同。這些指令除可以英語發音外，還可以使用法語、德語、西班牙語、荷蘭語和意大利語發音。駕駛者還可以通過設置參數來決定路線，比如說最快、最短、或不走高速公路的路線。

選項翻譯與答案詳解
1.從文章中我們得知，導航電腦__________________。
A)會大大提高汽車的銷售 B)可以幫助解決潛在的交通問題
C)很可能會被更多的司機所接愛 D)很快會被視作奢侈品的象征
根據文章第1段 這是一項正在發展的技術，而且其市場還有很大的潛力 ，可推斷，它將被越來越多的駕駛員接受。故選C。
2.有了導航電腦，司機就能很容易找到去目的地的最佳路線，方法是___________________。
A)輸入準確的地址 B)顯示汽車的位置
C)檢查電腦的數據庫 D)對電腦發出口頭指令
根據文章第5段 在大多數電腦系統中，駕駛員只需觸模屏幕輸入要去的地方即可 ，由此可推斷，輸入確切的目的地就是駕駛員唯一要做的事。因此，A正確。
3.雖然設計各不相同，車用導航電腦____________________。
A)價錢都差不多 B)指路的方式都-樣
C)原理基本一樣 D)從同樣的衛星接收指令
根據文章第5段 大多數電腦系統的工作原理基本上是一致的，區別只是在于硬件 電腦接受駕駛員指令的方式和電腦輸出駕駛指令的方式不同 ，因此，C正確。
4.導航電腦起作用，____________________。
A)是通過一個方向尋找器和一個速度檢測器實現的
B)基本上是依賴衛星信號和一個地圖數據庫
C)主要是通過接收逐步方向指令
D)使用一個屏幕來顯示衛星信號
根據文章第4段 衛星信號，連同車速傳感器提供的車速數據和定向儀提供的方向一起確定汽車前進時的位置。這些信息同一個地圖數據庫相結合 ，故B正確。
5.文章提到凌志，BMW和奧迪的車用導航系統，是為了顯示_____________________。
A)新技術的不成熟性 B)全球定位系統的優越性
C)汽車設備價錢波動的原因 D)為駕駛員指路的不同方式
根據文章第5段提出的觀點(見第3題)，在以下的幾段中，圍繞此觀點，文章具體舉例說明了安裝了導航電腦的這幾種車型在這兩方面到底有什么不同，也就是說在給駕駛員提供指令方面到底有什么不同。由此可推斷D正確。
