    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.
To reduce car crash rate, many scientists are working hard to______.
选项 A、design fully automatic cars
B、develop faster electric vehicles
C、analyze road deaths occurring worldwide each year
D、improve the safety of cars and develop new fuels
答案D
解析 本题的答案在第一段第二句话“much research now is focused on safety and new fuels”,所以正确答案是D,改善汽车的安全和发展新型燃料。
