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 risky. One advanced area of research in motoring safety is the use of digital in-car assistants(车内辅助设施). They can ensure you don’t miss important road signs or fall asleep. The use of artificial intelligence software allows these assistants to monitor your driving and make 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 find obstacles(障碍物) in fog, while other technology “sees through” big vehicles blocking your view.

And improvements to seat belts, pedal（制动踏板） controls and tyres(轮胎) 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.

But whatever is in the fuel tank, you don’t want a thief in the driving seat and there have been many innovations（革新）. 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（微妙的相互影响） 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 drivers, but their latest efforts suggest that won’t be soon.

61. What are researchers interested in doing as the road accidents worldwide increase to a shocking rate?

A. They are developing faster electric vehicles.

B. They are analyzing road deaths occurring worldwide every year

C. They concentrate their research on safety and new fuels

D. They are designing fully automatic cars

62. According to the second paragraph, most road accidents happen

A. because drivers fall asleep. B. because drives make mistakes.

C. because of engine failure. D. because of speeding.

63. Which of the safety development is NOT mentioned in the in the passage?

A. Radars that can help drivers to see obstacles in fog.

B. Devices that can help drivers to see through big vehicles.

C. Improvements in seat belts, pedal controls and tyres.

D. Windscreens that can help drivers to improve their vision.

64. What is NOT the purpose of innovations that use satellite tracking and remote communications?

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.

65. What is true of robotic drivers?

A. It will take some time before robotic drivers can 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.

61. C 根据文章第一段much research now is focused on safety and new fuels可知

62. B 第二段最后一句可知C错，A 和D中的fall asleep 和speeding 是人为原因，但只是部分人为因素，不能概全。

63. D 文中没提到windscreens, 所以选D

64. C根据第六段可知 C的内容文中没提到，所以选 C

65. A文中随后一段，B、C、D的内容文中均没提到；A句说，要实际使用机器人司机还需时日与文章末段最后一句表达意思相同
