    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 research aims at going faster.
    Travelling at speed has always been dangerous. One advanced area of research in motoring safety is the use of digital in-car assistants. They can ensure you don’t miss important road signs or fall asleep. 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" big vehicles blocking your view.
    And improvements to seat belts, pedal(脚踏) controls and tyres are making driving smoother and safer. The colour of a car has been found to be linked with safety, as have, les.s surprisingly, size and shape.
    But whatever is in the fuel tank, you don’t want a thief in the driving seat and there have been many innovations (创新). Satellite tracking and remote communications 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 tools. Robotic drivers could be programmed to make traffic flow smoothly and will perhaps one day be everyone’s personal chauffeur (司机) ,but their latest efforts suggest that won’t be soon.
Satellite tracking and remote communication systems can be used to______.
选项 A、reduce oil consumption
B、remove the obstacles on the road
C、call for help when one’s car crashes
D、help drivers get out of a traffic jam
答案C
解析 本题的答案可以直接从第五段倒数第一句话中找到“Satellite tracking and remote communications can also came into play if you crash,automatically calling for help.”这里come into play是开始起作用的意思。
