共享题干题 （二）Motoring Technology 根据材料，回答下列问题。 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 research aims at going faster. Travelling at ~peed 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 smoot-her and safer. The colour of a car has been found to be linked with safety, as have, less surpris-ingly, 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 toolso 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.1.[不定向选择题]To reduce car crash rate, many scientists are working hard to________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 2.[不定向选择题]Which of the following statements is true of robotic drivers?A.It will take some time before robotic drivers are available. B.Robotic drivers arnullnot allowed to drive on busy roads. C.Robotic drivers can never replace human drivers. D.Robotic drivers are too expensive to use.

1.参考答案：D
参考解析：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。
2.参考答案：A
参考解析：文章最后一句话指出机器人司机可以使交通运行更通畅，也许有一天机器人会成为每个人的私人司机，但是最近的研究表明这个愿望不会很快实现，这正是选项A所表达的意思“It will take some time before robotic drivers are available．”其他三个选项的内容文章根本就没有提及。3.[不定向选择题]Which of the following safety developments is NOT mentioned in the passage?A.Windscreens that can help drivers to improve their vision. B.Radars that can help drivers to see obstacles in fog. C.Devices that can help drivers to see through big vehicles. D.Improvements in seat belts, pedal controls and tyres.
