2022·全国乙卷·阅读理解C篇
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.　 　
[真题再做]
语篇解读：本文是一篇说明文。无人机将会在保证铁路的安全性和可靠性的同时，还能帮助铁路运营商每年节省大量费用。
1．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。根据第二段中的“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”可知，无人机已经被用于检查高压电线。它们同样可以被用来检查铁路线路和铁路基础设施的其他重要方面。由此可知，无人机已经被用于检查高压电线，这使得无人机在铁路线上的应用成为可能。
2．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“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.”可知，据计算，仅欧洲铁路每年就花费约200亿欧元用于维护，包括派遣维护人员、经常在夜间检查和维修铁路基础设施。由此可知，画线词指的是“检查和维修”。
3．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。根据最后一段中的“Engineers are now working on a new concept: the rail drones ... react in time.”可知，工程师们现在正在研究一个新概念：未来的铁路无人机。它们将在列车前方的轨道上运行，并被设定为自动运行。配备了先进传感器和人工智能的小型无人机可以像副驾驶员一样引导火车前进。它们有预见未来的能力，可以发出任何问题的信号，这样快速行驶的列车就能及时做出反应。由此可知，人们期待未来的铁路无人机具备提供早期预警的功能。
4．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：标题归纳题。根据第一段第一句和下文对无人机在铁路领域的应用的介绍以及对未来无人机的发展展望可知，在未来，无人机将会保证铁路的安全性和可靠性，或许会成为铁路安全的新未来。故D项“无人机将如何改变铁路的未来”最适合作本文的标题。
[素养发掘]
一、由典题悟通法
词义猜测题的思维建模(第2题)
思维建模 模型应用
第一步：定位 查找对应信息点 根据题干关键信息maintenance和in paragraph 3定位到第三段第一、二句。
第二步：理解 信息点的字面 意思 这包括大量节省成本和更好地保护铁路人员的安全。据计算，仅欧洲铁路每年就花费约200亿欧元用于维护，包括派遣维护人员经常在夜间检查和维修铁路基础设施。
第三步：分析 信息点与被猜测词义的语义关联和逻辑关系 由including可知，画线词maintenance 与inspect and repair表意一致。画线词意思是“检查和维修”。故选C。
