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.
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 tools. Robotic drivers could be programmed to make traffic flow smoothly and will perhaps one day be everyone’s personal chauffeur, but their latest efforts suggest that won’t be soon. (311 words)

1． C． 解析： 问题问“当世界范围内的道路事故发作率增加到了一个令人震惊的数量时, 研究者们对做什么产生了兴趣?”被选项C直接与文章主题照应(第1段第2句是答案相关句), 所以C是答案。
解题思绪2： 问题句中呈现了修饰词语（worldwide， shocking）， 应用这些修饰结构作为答案线索， 这样在文章中找到答案相关句：
1.2 million road deaths（死亡） worldwide（世界范围地） occur（发作） each year（每年）, plus（加上） a further（更多的） 50 million injuries（伤害）. To reduce（减少） car crash（撞车） rate, much research now is focused on（关注...） safety（安全） and new fuels（燃料） ? though some electric vehicle（电动汽车） and biofuel（生物燃料） research aims at（致力于） going（驾驶） faster.
第1段第1句是答案相关句（worldwide直接呈现，该句隐含shocking （rate）），但是该句并没有说“研究者们在做什么”， 因而关注后面的句子。 接下来的一句说“为了减少车祸发作率， 往常许多研究关注汽车的安全性和新型燃料的运用”，该句内容与C照应， 因而C是答案。 [page]
2. B．解析：问题问“依据第2段， 大多数车祸发作是因为...” 应用问题句中的修饰词most作为答案线索， 这样在文章中找到答案相关句（该段最后一句句子）
Most crashes（与most road accidents照应） result from（由...而产生） human and not mechanical(机械的) faults(错误, 毛病).
