二、阅读理解
阅读下列短文,从每题所给的A、B、C、D四个选项中选出最佳选项。
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.
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.
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.
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.
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

I have always been rather quiet and never been able to make friends 4 . I would always forget names after I met people. When we 5 again and they called out my name, I would reply with a(n) 6 wave and a weak hello. This was how things went on for the first month or so. After a while, things started to 7 . A couple of my roommates would try and keep me talking. Soon, these two roommates and I started becoming fairly 8 . We began going to the cafeteria together, 9 together, and meeting in the library to study.
One night my roommates invited me to listen to a fellow roommate's practice with one of our college choirs. They drove me to the campus where my roommate was to 10 .
It was accidental that that day was my birthday, but I had kept quiet about it. So you can imagine my 11 when we entered the recital hall. The 120-member choir began to sing Happy Birthday to me. 12 at the dorm, my friends held a small party for me, complete with a card and a cake.

3.答案:A
解析:理解具体信息。题干问的是期待铁路无人机有什么样的功能。根据文章最后一段最后一句"With their ability to see ahead, they could signal any problem, so that fast-moving trains would be able to react in time"(因为能提前看到, 无人机可以感知到任何问题, 这样快速前进的列车就可以及时作出反应)可知, 期待铁路无人机具有的功能是提前发现问题, 并给列车发出警告。故A项正确。
4.答案:D
解析:理解文章主旨要义。题干问的是本文最佳标题是什么。第一段是导入, 综述无人机在铁路运营方面的应用前景; 第二段主要讲述无人机在铁路运营中的部分功能和作用; 第三段主要讲了无人机在降低铁路维护成本和维护铁路职员人身安全方面的作用; 第四段讲无人机还能为铁路运营做的事情。由此可知本篇文章主要讲的是无人机将如何改变铁路的未来。故D项正确。
