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 true of robotic drivers?
选项
A、It will take some time before robotic drivers can be put to practical use.
B、Robotic drivers are not allowed to drive on busy roads.
C、Robotic drivers can never replace human drivers.
D、Robotic drivers are too expensive to use.
答案
A
解析
可定位在文章最后一句:Robotic drivers could be programmed to make traffic flow smoothly...that won’t be soon.最后一句指出:为机器人司机编制程序后,它们能使交通变得顺畅,也许今后某一天,大家都拥有机器人司机,但这一天的到来还有待时日。选项B、C、D三项的内容在文中都没有提到,选项A说,要实际使用机器人司机还需时日,这显然与末段最后一句表达的意思相吻合,故选项A正确。
