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.

People need transportation to move from one place to another. As time went by, transportation methods improved. Especially after the invention of airplanes, they made travel more convenient and 【小题1】 （easy）.

The airplane 【小题2】 （invent）by Orville and Wilbur Wright in 1903. 【小题3】 first airplane, Wright Flyer I, flew 36.5 meters in 12 seconds. After that, the two brothers kept 【小题4】 （improve）their airplanes. They 【小题5】 （fly）in public in France in 1908, and started taking passengers with them. Ever since, many other people made great efforts to improve and develop airplanes. Thanks to their efforts, airplane technology developed 【小题6】 （extreme）fast.

Today, airplanes have many different 【小题7】 （apply）. People can use airplanes to travel to other countries, send urgent mails and help people 【小题8】 danger. They use airplanes to send water, food, medicine, etc. to cities that need help. However, airplanes are not only used in positive ways,   【小题9】 they are also used to fight wars.

Many things 【小题10】 （change）since the invention of the airplane. Airplanes have made travel or transport faster. Airplanes have really changed our lives.

China speed is amazing the world. While other countries are struggling to make high-speed railway a 【小题1】   (real), the China Railway Corporation has been busying itself in laying down over 25,000 km of high-speed tracks over the past ten years — accounting for roughly two 【小题2】(three) of the world’s total length of high-speed rail lines.

Up to now, China 【小题3】(build) the largest high-speed rail network worldwide. The impacts go well beyond the railway sector. It also includes changed patterns of urban development, increases in tourism, and growth of regional economy. To boost regional integration and economic growth, plans for high-speed maglev (磁悬浮) lines with trains 【小题4】 (travel) at a speed of 600 kph or more are taking shape in more Chinese cities.

“China started operating 【小题5】 (it) first maglev railway more than a decade ago. 【小题6】, for lack of critical technologies at that time, we only concentrated on conventional high-speed rail,” said Sun Zhang, 【小题7】 is a leading railway specialist. But the research team, 【小题8】 (lead) by him, tried their best to learn advanced technologies from foreign countries and eventually developed our own innovations.

There is no denying that all of these achievements make our travel convenient and     【小题9】( rely) , especially during “Chunyun”, 【小题10】 annual test on the China's transportation system. Thanks to “China speed”, people can go back home for reunions with families and friends in time.
