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] According to the second paragraph, most road accidents happen______.
选项
A、because drivers fall asleep
B、because drivers make mistakes
C、because of engine failure
D、because of speeding
答案
B
解析
可定位在第2段最后一句:Most crashes result from human and not mechanical faults.利用问题句中的修饰词most作为答案线索,在文章中找到答案相关句:大多数汽车撞车事故是人为原因造成,而非机械故障,所以C是错误选项,A和D中的fall asleep和speeding是人为原因,但只是人犯错的部分因素,故选项B正确。
