Could you help me check them for me

• Is train travel very common in your country?
Yes, it is. China is a huge country and people often live and work far from their hometown. Train is the most common transport tool they use when they go from and back hometowns because of its low prices and safety.

• Do you often travel by train?
Not very often. I only travel by it when I go from and back to my hometown , about 2000 kilometers from here, during new lunar year. During that busy time, air tickets are a lot more expensive than train tickets. Traveling by train can save me a lot of money, although it's a little bit uncomfortable and time-consuming.

• Do you like traveling by train?
Of course. Traveling by train is a good change to see the landscape along railways.

• What do you usually do when (you are) traveling by train?
I usually read or chat with other people around me, which I think is a good way to start new friendship with strangers.

• What do you think are the benefits of traveling by train?
Trains are an increasingly cost-effective alternative to planes, particularly if I'm going a relatively short distance, within 500 kilometers. Also, Trains are more energy-efficient per passenger mile compared with planes or cars, making them one of the most eco-friendly transportation options around. Carbon emissions from them are less damaging to the environment than those of airplanes because train emissions are not released directly into the upper atmosphere.

• Is there a subway system in your city?
Yes, there is. I commute to work by riding subway, the fastest transport tool.

• Do you ever travel by subway?
Of course. I ride the subway everyday to commute to work.
