问题                              Virtual Driver
    Driving involves sharp eyes and keen ears, analyzing with a brain, and coordination between hands, feet and brain. A man has sharp eyes and keen ears, analyzes through his brain, and maintains coordination between his hands and brains. He can control a fast-moving car with different parts of his body. 【T1】______Apparently there isn’ t anyone in the driver’ s cab, but there is in fact a virtual driverl. This virtual driver has eyes, brains, hands and feet too. The mini cameras on each side of the car are its eyes and are responsible for observing the road conditions ahead of it as well as the traffic to its left and right. If you open the boot, you can see the most important part of the automatic driving system: a built-in computer. 【T2】______The brain of the car is responsible for calculating the speeds objects surrounding the car are moving at2, analyzing their position on the road, choosing the right path, and giving orders to the wheel and the control system.
    In comparison with the human brain, the virtual driver’s best advantage is that it reacts quickly. 【T3】______However, it takes the world’s best racecar driver at least one second to react, and this doesn’ t include the time he needs to take action.
    With its rapid reaction and accurate control, the virtual driver can reduce the accident rate on expressways considerably. In this case, is it possible for us to let it have the wheel3 at any time and in any place?【T4】______With its limited ability to recognize things, the car can now only travel on expressways.
    The intelligent car determines its direction by the clear lines that mark the lanes clearly and recognizes vehicles according to their regular shapes. 【T5】______This being the case4, people still have high hopes about driverless cars, and think highly intelligent cars are what the cars of the future should be like5.
A. Experts say that we cannot do that just yet.
B. In the near future, intelligent cars will be put into commercial operation.
C. This is the brain of the car.
D. But how does an intelligent car control itself?
E. It completes the processing of the images sent by the cameras within 100 milliseconds.
F. However, it cannot recognize moving people and bicycles on ordinary roads that have no clear markings on them.  
【T3】

选项

答案E

解析 空格28前面一句提到,虚拟驾驶员最大的优点是反应快。空格后面一句说,最好的赛车手至少要1秒钟才能作出反应。“至少要1秒钟”已经暗示,虚拟驾驶员反应速度要比真人驾驶员快。选项E“虚拟驾驶员只需100毫秒就能作出反应”。可使上下文的意思完整,因此是答案。
