It seems that travelling is very important in modern(现代的)life. The fastest way of trav- elling is by plane. You can travel by plane in one day to a place that it took a month or more to
get to a hundred years ago.
Travelling by train is slower than by plane. But it has its advantages(优势). You can enjoy the scenery of the places you're travelling through. Modern trains have comfortable seats and.dining cars.
Some people like to travel by sea sometimes. There are large liners or river boats. You can visit many other countries and different parts of your country on them. Ships are not so fast as trains or planes ,but travelling by sea is a very pleasant way to spend a holiday.Many people like to travel by car. You can make your own timetable(时间表). You can travel three or four hundred miles or only fifty or one hundred miles a day ,just as you like.You can stop wherever you wish-at a place where there is something interesting to see ,at a good restaurant where you can enjoy a good meal ,or at a hotel to spend the night. That is why trav-elling by car is popular for pleasant trips ,while people usually take trains or planes when they are travelling on business.
