问题     京广高速铁路客运专线(简称“京广高铁”)是以客运为主的高速铁路。这条铁路线途经大半个中国，全长2 298千米，是世界上最长的高速铁路线路。过去，从北京到广州的火车旅程需要20个小时，但是由于京广高速铁路的开通，这段时间将缩短到8个小时。每天总共有155组列车以平均300千米／小时的速度行驶在这条铁路上。这条新铁路有一系列的措施来保证其安全性，这些措施包括增加对设备的维修(maintenance)、提升控制系统以解决可能发生的问题。
选项
答案     Beijing-Guangzhou High-Speed Railway (abbreviated to Jing-Guang High-Speed Railway) is a high-speed passenger train. The rail line runs through over half of China covering 2 298 km. It is the longest high-speed rail line in the world. It used to take 20 hours to travel by train from Beijing to Guangzhou. But the travel time has been cut to eight hours—as the Beijing-Guangzhou high-speed rail line opened. A total of 155 pairs of trains will run on the line every day at an average speed of 300 km per hour. The new line has a series of measures in place to make sure it’s safe, including increasing maintenance for equipment and improving the control system to try to solve possible problems.
