4 研真题 链接高考
(2022全国乙卷,阅读理解C)——无人机技术在铁路方面的应用
Can a small group of drones(无人机) guarantee the safety and reliability of railways and,at the same time,help railway operators save billions of euros each year That is the very likely future of applying today’s “eyes in the sky” technology to making sure that the millions of kilometres of rail tracks and infrastructure(基础设施) worldwide are safe for trains on a 24/7 basis.
Drones are already being used to examine high-tension electrical lines.They could do precisely the same thing to inspect railway lines and other vital aspects of rail infrastructure such as the correct position of railway tracks and switching points.The more regularly they can be inspected,the more railway safety,reliability and on-time performance will be improved.Costs would be cut and operations would be more efficient(高效) across the board.
That includes huge savings in maintenance costs and better protection of railway personnel safety.It is calculated that European railways alone spend approximately 20 billion euros a year on maintenance,including sending maintenance staff,often at night,to inspect and repair the rail infrastructure. That can be dangerous work that could be avoided with drones assisting the crews’ efforts.
By using the latest technologies,drones could also start providing higher-value services for railways,detecting faults in the rail or switches,before they can cause any safety problems.To perform these tasks,drones for rail don’t need to be flying overhead.Engineers are now working on a new concept:the
rail drones of the future.They will be moving on the track ahead of the train, and programmed to run autonomously.Very small drones with advanced sensors and AI and travelling ahead of the train could guide it like a co-pilot.With their ability to see ahead,they could signal any problem,so that fast-moving trains would be able to react in time.
一、理清脉络
二、真题再做
28.What makes the application of drones to rail lines possible
A.The use of drones in checking on power lines.
B.Drones’ ability to work at high altitudes.
C.The reduction of cost in designing drones.
D.Drones’ reliable performance in remote areas.
答案 A　
解析 细节理解题。根据第二段第一句可知,无人机目前正在被用来检查高压电线,这使得它将被应用于铁路系统成为可能。故选A项。
29.What does “maintenance” underlined in paragraph 3 refer to
A.Personnel safety.
B.Assistance from drones.
C.Inspection and repair.
D.Construction of infrastructure.
答案 C　
解析 词义猜测题。根据第三段中的“to inspect and repair the rail infrastructure”可以推断出,画线单词指的就是“维修,维护”。故选C项。
30.What function is expected of the rail drones
A.To provide early warning.
B.To make trains run automatically.
C.To earn profits for the crews.
D.To accelerate transportation.
答案 A　
解析 细节理解题。根据最后一段的第一句和最后一句可知,人们期盼铁路无人机在未来能够提供预先警报,确保列车能及时应对问题,从而提高安全系数。故选A项。
31.Which is the most suitable title for the text
A.What Faults Can Be Detected with Drones
B.How Production of Drones Can Be Expanded
C.What Difficulty Drone Development Will Face
D.How Drones Will Change the Future of Railways
答案 D　
解析 主旨大意题。通读全文内容可知,文章主要介绍了无人机目前的应用范围以及未来在铁路方面的应用方向,因此“无人机将如何改变铁路的未来”最能概括文章内容。故选D项。
