The faster way to travel in a city is by subway. In many big cities, there ____ usually more than one subway lines. How to travel by ____? Here is something to know ____ you travel by subway. First, you should choose the right line. If you don’t, you will have to get off and take ____ one. Second, you need some coins (硬币) to buy your ____. In ____ of the ticket machines, only coins are used. You can change (换) ____ at the ticket office. If you have a prepaid (预付款) card, you can just go ahead. After you buy the ticket, you should ____ the train behind a yellow line. You ____ stand too close to the yellow line. It's ____.

Many of you have probably had this experience: You get on a train and are ready to take a nap or read a book, only to find that the passenger in front of you is watching a TV show on his tablet without headphones. The child next to you won’t stop crying. And the old lady behind you talks on her phone during the whole trip.

Wish the train could be less noisy? There might be a solution for you. The Beijing-Shanghai high-speed railway, one of China’s busiest high-speed rail lines, have had “quiet” carriages starting since Dec 23, 2020.

In quiet carriages, on board videos are muted (静音) and announcements are made at a lower volume (音量). Doors at the ends of the carriage are kept closed to reduce noise from other carriages. Train attendants (乘务员) are responsible for making sure that passengers remain quiet and follow the rules.

Passengers who are willing to obey the rules can choose the quiet carriages when booking their tickets, according to China’s national railway operator.

Some people have pointed out that this kind of quiet environment should be offered in all carriages. They say that having quiet carriages might give people the impression that they don’t need to be quiet in non-quiet carriages.

Quiet carriages might be more enjoyable. While some internet users are in favor of the new service, it has also sparked discussion about just how quiet travelers should be in quiet carriages. Many people have raised questions such as “What if I snore (打呼噜)?” and “Can we talk to our travel companions if we need to?”
