Do you know the self-driving bullet (子弹) train just for the Beijing Winter Olympics? Is there anything new on the train? Let’s have a look!
The train links (连接) Beijing and Zhangjiakou, the co-host cities of the Games. With a top speed of 350 kilometers an hour, the train can run the 174-kilometer journey between the two cities in around 50 minutes, while a regular express (特快的) train takes three hours.
It is said to be the world’s first high-speed train with a 5G live broadcast studio (现场直播演播室). It can carry 564 passengers each trip in its eight cars (车厢). It has business, first-class and second-class cars. Besides, for the needs of media (媒体), it also has special working cars with 12 tables and international electric sockets (电源插座).
The train is painted in white and blue colors and there are 24 snowflakes (雪花) on the outside of the train, showing this is the 24th Winter Olympic Games. Inside the train, there are winter sports photos on the walls and paper snowflakes on top.
The Beijing Winter Olympic Games opened in February, 2022. The high-speed train provided transportation services for the 2022 Winter Olympics and the Paralympics (残奥会) from January 21 to March 16. Up to 40 pairs of trains traveled between the two cities every day.
1．Which two cities does the train link?2．Can the train run faster than a regular express train?
3．How many kinds of cars does the train have according to the passage?
4．What do the 24 snowflakes stand for (代表)?
5．What does the passage mainly talk about?
