China has built a high-speed passenger rail network in recent 【小题1】 (year) and will continue to expand it. By the end of 2018, China’s high-speed railway mileage (总长度) 【小题2】 (reach) 29,000 kilometres. This accounted for 2/3 of the world’s total high-speed rail tracks, 【小题3】 (make) China’s high-speed rail system become the world’s 【小题4】 (large) high-speed rail network.

China’s high-speed trains are similar 【小题5】 those of France’s TGV, German’s ICE and Japan’s Shinkansen. The fast train 【小题6】 top speed is 250-350 km/h is called CRH, China Railway High-speed.

If you want to travel around China, the high-speed trains will be your ideal choice since they are clean, comfortable 【小题7】 modern. Unlike the old trains in the past in China, nobody is allowed 【小题8】 (smoke) on high-speed trains, not even between carriages.

The seats are as good as those on the plane or even better. Most high-speed rail tickets have corresponding (对应的) seats, and only 【小题9】 small number of standing tickets are sometimes sold on limited trains. The ticket prices for China’s high-speed trains are reasonable, and people can buy tickets 【小题10】 (convenient).

The Grand Canal of China was first dug in 486 BC, and well developed through the late 6th to early 10th century. From the late 13th until 19th century, with the highest section built and the overall length 【小题1】(shorten), the Canal was turned into a main passage between northern 【小题2】 southern China as well as the economic lifeline of the country. Consisting of the Sui and Tang Grand Canal, the Jing-Hang Grand Canal and the Zhedong Canal, the Canal 【小题3】(stretch) over 2, 700 kilometers, crossing eight provincial-level administrative regions and 【小题4】(link) five major water systems. The Grand Canal also connects with the Eurasian Silk Road to the west and extends the water trade route to the east.

The Grand Canal was 【小题5】 notable achievement of the ancient Chinese people. Its connection of the political and economic centers played a 【小题6】(centre) role in the political unity, economic 【小题7】(grow) and cultural prosperity of China, and contributed to the livelihood, exchanges and integration of the population along its route.

The Grand Canal 【小题8】(announce) by the State Council as one of the seventh batch of Major Historical and Cultural Sites Protected at the National Level in March, 2013 and registered 【小题9】 the UNSECO World Heritage List in June, 2014. This large-scale, living cultural heritage spreads like a huge dragon across the vast territory of China, 【小题10】(it) ripples shining golden scales (鳞片) in the new age.

With the【小题1】(adopt) of e-ticket service on the high-speed line【小题2】(link) Lanzhou of Gansu province and Urumqi of the Xinjiang Uygur autonomous region on Wednesday, all 1,075 high-speed and intercity railway stations on the Chinese mainland will allow passengers to check in【小题3】a paper ticket. The move will streamline boarding procedures and improve services.

【小题4】entering the station and checking in, passengers only need【小题5】(scan) an identification card at the self-service counters. Those【小题6】ID cannot be read by the machines will be able to check in through the manual channel.

The service【小题7】(introduce) on the island-looping high-speed rail line of Hainan province in November 2018. It was then promoted to the majority of the high-speed railway stations across the country during the【小题8】(four) quarter last year.

After going through tests of the robust traffic during the Spring Festival, summer vacation and other holidays, the e-ticket system has been operating【小题9】(safe) and steadily while getting positive passenger feedback.

The system has also grouped【小题10】disabled, people with children, students and the military in online accessibility to discounted tickets.
