An Intelligent Car

Driving needs sharp eyes, keen ears, quick brain, and coordination between hands and the brain. Many human drivers have all 1 and can control a fast-moving car. But how does an intelligent car control itself?

There is a virtual driver1 in the smart car. This virtual driver1 has “eyes,” “brains,” “hands” and “feet,” too. The minicameras 2 each side of the car are his “eyes,” which observe the road conditions ahead of it. They watch the 3 to the car’s left and right. There is also a highly 4 driving system in the car. It is the built-in computer, which is the virtual driver’s “brain.” His “brain” calculates the speeds of 5 moving cars near it and analyzes their positions. Basing on this information2, it chooses the right 6 for the intelligent car, and gives to the “hands” and “feet” to act accordingly. In this way, the virtual driver controls his car.

What is the virtual driver’s best advantage3? He reacts 8 . The minicameras are 9 images continuously to the “brain.” It 10 the processing of the images within 100 milliseconds. However, the world’s best driver 11 needs one second to react. 12 , when he takes action, he needs one more second.

The virtual driver is really wonderful. He can reduce the accident 13 considerably on expressways. In this case, can we let him have the wheel4 at any time and in any place? Experts 14 that we cannot do that5 just yet6. His ability to recognize things is still 15 . He can now only drive an intelligent car on expressways.

詞匯: coordination n. 協調,協同

accordingly adj. 相應地 virtual adj. 虛擬的

millisecond n. 毫秒 minicamera n. 微型相機 expressway n. 高速公路注釋:

1. virtual driver:虛擬駕駛員

2. Basing on this information:基于這些信息。 Basing on this information是現在分詞短語,用作狀語。

3. best advantage:昀大的優點

4. have the wheel:掌握方向盤,也就是“駕駛汽車”的意思。

5. that:that替代上一句的“ let him have the wheel at any time and in any place”。

6. just yet:迄今還。 yet意為“迄今還”,常用于否定句中。 Just修飾 yet,起強調的作用。

練習:

1. A these B them C this D that

2. A within B above C to D on

3. A police B traffic C trucks D buses

4. A mechanical B movable C automatic D electronic

5. A another B other C each other D one another

6. A line B lane C track D path

7. A space B location C instructions D time

8. A quickly B cleverly C virtually sending D safely

9. A bringing B taking C sending D carrying

10. A selects B completes C uses D tests

11. A at least B at most C at last D at best

12. A So B However C Besides D Therefore

13. A count B amount C digit D rate

14. A warn B suggest C invite D check

15. A unknown B few C untested D limited

答案:1. A第一句提到的是 eyes,ears,brain等,指示代詞應該用復數形式的 these,不能選 this或 that。選 them也不對,因為 all them不符合習慣用法,正確的說法是 all of them。

2. D side前面要求用介詞 on。

3. B選項 B:traffic意思是“流動的車輛”,是本題的答案。 police (警察)、trucks(重型卡車)和 buses(公共汽車)表達的意思都是路況的一部分,顯然與現實不符。

4. C 從上下文判斷,本句的意思應該是高度自動化的駕駛系統,所以答案是 automatic。其余三個選項(mechanical機械的, movable可移動的, electronic電子的)表達的意思與上下文配不上。

5. B 從上下文判斷,本句說的是“其他流動的車輛”,所以要選用 other。Another意為“另一個”, each other和 one another都是“互相”的意思,與上下文表達的意思相去甚遠。

6. D 上下文的意思要求選 path(路徑)。 line(線路)lane(車道)和 track(車轍),意思雖與 path接近,顯然講不通。

7. C 本句的前半句說的是電腦選定了路徑,接下來自然是“……給‘手’發出指令( instructions),‘手’就做出相應的動作”。所以 C是答案。 space,locations,time的詞義與上下文的意思銜接不上。

8. A 通段講的是虛擬駕駛員的反應速度,所以只能選 quickly。

9. C bring是“帶來”, take是“帶走,接受(命令)”, send是“發送(命令)”, carry是“攜帶”。從上下文判斷,應該是“… sending images continuously to the ‘brain’”。

10. B前一句說的是微型攝像機將圖像送入電腦,接下來的意思應該是電腦處理圖像,完成處理圖像所需的時間為 100毫秒。根據上下文表達的意思,應該選 B。

11. A 本句的起始詞是 However,表示本句的意思與上一句的意思形成對比。上一句說電腦完成圖像處理只需 100毫秒,第二句說,昀好的駕駛員處理的時間要長得多,應該是 at least need one second。

12. C上一句說,昀好的駕駛員至少需要 1秒的時間才能完成圖像處理。本句進一步說,他做出動作還需 1秒的時間,這兩句的意思是層層深入,所以要選 Besides。

13. D 根據上下文判斷 ,“accident + ?”要表達的應該是“事故率”。 Rate是“比率”,所以,答案是 D。count(計數), amount(數量)、 digit(0到 9中任何一個阿拉伯數字 )都不對。

14. C “can we let him have the wheel at any time and in any place?”涉及交通安全、人命關天的問題,能就是能,不能就是不能:什么“邀請( invite)”、“建議( suggest)、“檢查( check)”。都談不上。所以,答案只能是 warn(警告)。

15. D 本句是給出目前不能 let smart car have the wheel at any time and in any place的原因。原因是它的能力 limited (有限)。對 smart car的能力一無所知( unknown)或是沒有測試過( untested),顯然與前文的意思不符。few只能與可數名詞搭配, ability在本句中是不可數名詞,所以, few也不是答案。
