(2022全国乙卷,阅读理解C)——科学与技术Can a small grup f drnes(无人机) guarantee the safety and reliability f railways and,at the same time,help railway peratrs save billins f eurs each year?That is the very likely future f applying tday’s “eyes in the sky” technlgy t making sure that the millins f kilmetres f rail tracks and infrastructure(基础设施) wrldwide are safe fr trains n a 24/7 basis.
Drnes are already being used t examine high-tensin electrical lines. They culd d precisely the same thing t inspect railway lines and ther vital aspects f rail infrastructure such as the crrect psitin f railway tracks and switching pints.The mre regularly they can be inspected,the mre railway safety,reliability and n-time perfrmance will be imprved.Csts wuld be cut and peratins wuld be mre efficient(高效) acrss the bard.
That includes huge savings in maintenance csts and better prtectin f railway persnnel safety.It is calculated that Eurpean railways alne spend apprximately 20 billin eurs a year n maintenance,including sending maintenance staff,ften at night,t inspect and repair the rail infrastructure. That can be dangerus wrk that culd be avided with drnes assisting the crews’ effrts.
By using the latest technlgies,drnes culd als start prviding higher-value services fr railways,detecting faults in the rail r switches,befre they can cause any safety prblems.T perfrm these tasks,drnes fr rail dn’t need t be flying verhead.Engineers are nw wrking n a new cncept:the rail drnes f the future.They will be mving n the track ahead f the train, and prgrammed t run autnmusly.Very small drnes with advanced sensrs and AI and travelling ahead f the train culd guide it like a c-pilt. With their ability t see ahead,they culd signal any prblem,s that fast-mving trains wuld be able t react in time.
真题再做28.What makes the applicatin f drnes t rail lines pssible?A.The use f drnes in checking n pwer ’ ability t wrk at high reductin f cst in designing ’ reliable perfrmance in remte 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 des “maintenance” underlined in paragraph 3 refer t?A.Persnnel frm and f infrastructure.答案 C解析 词义猜测题。根据第三段中的“t 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 functin is expected f the rail drnes?A.T prvide early make trains run earn prfits fr the accelerate transprtatin.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 mst suitable title fr the text?A.What Faults Can Be Detected with DrnesB.Hw Prductin f Drnes Can Be ExpandedC.What Difficulty Drne Develpment Will FaceD.Hw Drnes Will Change the Future f 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。
