      We can not live a modern life without traveling. The fastest way of traveling is by air. With a

plane one 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 one can see the country he is traveling through.

Modern trains have comfortable seats and dinning-cars. They make even the longest journey

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 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.
