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] What is NOT the purpose of innovations that use satellite tracking and remote communications?
选项
A、To prevent car thieves from getting into your car.
B、To call for help when one’s car crashes.
C、To call for help when the car gets jammed in the traffic.
D、To track the car down when it is being stolen.
答案
C
解析
可定位在第6段。问题句中出现的细节信息结构(satellite tracking和remote communications)可作为答案线索,这样在文章中找到答案相关句: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.说明一些革新技术使用卫星和远程通信来防御汽车盗贼(与A和D呼应),如果你撞了车,这些通信系统也能起作用:它能自动寻求帮助(与B呼应),因此选项C正确。
