Travel by train
Jack loves traveling by train. Whenever he feels like traveling, he'd first think about taking a trip on the
rail. That is because he never has to bother to book (订) tickets or collect them in advance (提前). Going to
the station and buying a ticket are what he has to do.
Traveling by train is also very comfortable. Most of the trains are air-conditioned, warm in winter and
cool in summer. Jack usually chooses a non-smoking section, taking a seat by the window so he can enjoy
the outside views. If it is a night train, the experience can be exciting. He just sleeps the whole night and the
next day, he will be in a new city. By the way, he never has to worry about his meals. The train provides
food around the clock.
Traveling by train has another advantage to offer: you may run into some old friends or you can listen
to people talking about something of your interest. Last week when he was on a train, for instance, he ran
into a primary school classmate. They didn't expect that they could bump into each other that way. Their
talk brought back many things: the games they played, the jokes they made on their peers and the funny
things they had done.
