问题 共用题干Motoring Technology
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 speed 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 tools.
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.Which of the following statements is true of robotic drivers?A: It will take some time before robotic drivers are available.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.
选项 Which of the following statements is true of robotic drivers?
A: It will take some time before robotic drivers are available.
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 本题的答案在第一段第二句话“much research now is focused on safety and new fu-els"，所以正确答案是D，改善汽车的安全和发展新型燃料。


第二段最后一句话明确指出“most crashes result from human and not mechanical faults"，选项B中human mistakes即human faults.


选项B和C的内容在文中第三段提到“Radar can spot obstacles in fog , while other technology ‘ sees through ’ big vehicles blocking your view”，选项D在第四段中第一句话 提到“...improvements to seat belts,pedal controls and tyres are making driving smoother and safer.”只有选项A未被提及。


本题的答案可以直接从第五段倒数第一句话中找到“Satellite tracking and remote communications can also came into play if you crash , automatically calling for help.”这里 come into play是开始起作用的意思。


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。
