  We can not live a modern life without traveling. The fastest way of

traveling is by air. With a plane people can travel in one day to places which it

took a month or more to get to a hundred years ago.

  Traveling by train is slower than by plane, but people can see the country

when they are traveling through. Modern trains have comfortable seats and

dinning-cars. They make even the longest journey(旅途) enjoyable.

  Some people prefer to travel by sea when possible. There are large luxury

liners(客轮) or river boats. They are not as fast as trains or planes, but traveling

by sea is a very pleasant way to spend a holiday.

  Many people like to travel by car. They can make their own timetable. They

can travel hundreds of miles or only fifty miles a day, just as their wish. They can

stop wherever they want to see something interesting or to enjoy a good meal at a

good restaurant, or to spend the night at a hotel. That is why people choose

traveling by car for pleasant trips, while they usually take trains or planes for

business.
