问题     1.2 million road deaths worldwide occur each year, plus a further 50 million injuries. To reduce car crash rate, much research now is focused on safety and new fuels — though some electric vehicle and biofuel (生物燃料) research aims at going faster.
    Traveling at speed has always been risky. One cutting edge area of research in motoring safety is the use of digital in-car assistants. They can ensure you don’t miss crucial road signs or fall asleep. The use of artificial intelligence software allows these assistants to monitor your driving and makes sure your phone or radio doesn’t distract you at a vital moment. Most crashes result from human and not mechanical faults.
    Some safety developments aim to improve your vision. Radar can spot obstacles in fog, while other technology "sees through" high-sided vehicles blocking your view.
    And improvements to seat belts, pedal controls and tyres are making driving smoother and safer. The color of a car has been found to be linked with safety, as have, less surprisingly, size and shape.
    And alternatives to fossil-fuel based petrol, such as plant oils, are a hot area of research. Fuel cells based on hydrogen burn cleanly, and are the subject of a serious research effort.
    But whatever is in the fuel tank, you don’t want a thief in the driving seat and there have been many innovations, some using satellite tracking and remote communications, to fight against car theft. These communication systems can also come into play if you crash, automatically calling for help.
    Accidents cause many traffic jams, but there are more subtle interplays between vehicles that can cause jams even on a clear but busy road, such jams can be analyzed using statistical (统计数字的) tools. Robotic drivers could be programmed to make traffic flow smoothly and will perhaps one day be everyone’s personal chauffeur (法语，司机), but their latest efforts suggest that won’t be soon. [br] Which of the safety developments is NOT mentioned in the passage?
选项 A、Radars that can help drivers to see obstacles in fog.
B、Devices that help drivers to see through big vehicles.
C、Improvements in seat belts, pedal controls and tyres.
D、Windscreens that can help drivers to improve their vision.
答案 D
解析 可定位在第3段第2句和第4段第1句：Radar can spot obstacles…making driving smoother and safer．问题句中没有词语或结构可作为答案线索，因此关注被选项，被选项中均涉及细节信息，因此分别利用被选项中的细节信息词作为答案线索，选项A中提及radar(雷达)，选项B提到devices to see through big vehicles(在雾中看清大型车辆)，选项C提到seat belt，pedal controls，tyres(安全带、刹车控制和轮胎)，选项D中提到windscreens(汽车挡风玻璃)，只有D选项在文中没有提及，故选项D正确。
