During the past three decades,China【小题1】 (witness)the railway industry’s transformation from making slow trains 【小题2】 making domestically manufactured high-speed trains

In 1997,China started 【小题3】 (it)first significant railway speed increase. Since then, the country’s high-speed rail technology has continued to achieve breakthroughs250 km/h to 350 km/h and then to 400 km/h.Made-in-China high-speed trains not only operate 【小题4】 (smooth) in freezing weather and desert【小题5】 (region),but they also come with driverless technology Millions of railway workers take pride in their roles as the company provides【小题6】 clear route for their professional advancement.Through【小题7】 (train), practical operation and assessment, they can move up as a wiring worker to a technician, an operator an expert and even a scientist

As trains become faster and more intelligent, their software and hardware systems will become more complex thus requiring【小题8】 (high)technical competence for daily maintenance by railway workers. For these diligent railway workers【小题9】 have skilled craftsmanship, improving their skills tirelessly to ensure safe operation of the trains seems like an 【小题10】 (end)learning curve throughout life.

Beijing Daxing International Airport opened for operations in September 2019, following upwards of four years of construction. The new Beijing airport was built on a 6,620 acre site 【小题1】(locate) 46 km south of Beijing's political center, Tiananmen Square.

China 【小题2】(project) to overtake the United States as the world's 【小题3】 (big) air travel market by 2022. This new modern airport employs a special intelligent lighting system, supported by eight big C-shaped columns 【小题4】 let in the sunlight, 【小题5】(bright) the architecture and structure. Therefore, it minimizes the need to use electric lighting. 【小题6】(offer) a more refreshing travel experience, five outdoor courtyards with the themes "Silk Garden”，“Tea Garden”，“Porcelain Garden”，“Countryside Garden" and “Chinese Garden" are featured at the end of the five departure lounges (等候室) 【小题7】 use by passengers waiting for their flights. Travelers will be scanned on cameras using facial 【小题8】(recognize). Counters will be fully automated to capture face 【小题9】(photo) and relay them over each part of the journey through the airport, including security and the departure gate.

The “modest” initial operational target at Daxing is to accommodate 72 million passengers and 2 million tons of commodities annually by 2025. The ambitious master plan calls for the building of a total of seven runways, 【小题10】moving at least 100 million passengers and 4 million tons of commodities a year through the airport.

China has built a high-speed passenger rail network in recent years and will continue to enlarge 【小题1】 (rapid). By the end of 2017, China's railway mileage 【小题2】 (reach) 127, 000 kilometers, and 25,000 km of it are high-speed rail, 【小题3】 makes China's high-speed system the world's 【小题4】 (large) high-speed network.

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

If you want to travel around China, the high-speed trains will be your ideal vehicle since they are clean, comfortable and modern. Unlike the traditional trains in China, no smoking 【小题6】 (allow) on high-speed trains, not even between carriages.

To meet the 【小题7】 (require) of different passengers, the high-speed railway operators have divided CRH tickets into three types. They are business, first class and second class. There's never a mad crowd with many people 【小题8】 (sit) in the aisles as well as in seats.

The ticket prices for China's high-speed trains are reasonable 【小题9】, on most routes, the frequency of departure is very high, so it's quite convenient for people 【小题10】 (buy) tickets.
