Travelling by train
     In Western countries, if people want to travel from a city to another, they would like to take a train.
 Like in China,there are expresses (快车) and locals (慢车) in these countries. Express trains usually
 travel  fast and local trains usually stop at all stops.
     In a special grade (等级) train, there is a kind of compartment (车厢) called Pullman(卧车).There
 are  sofas, tables, chairs and other things in it. People feel more comfortable (舒适的) there. Of course,
 they  will pay more for it.
     When people take a train, they would like to buy return tickets (返程票). If they want to take the
 Pullman, they should book the tickets.
