9、Modern life is impossible without traveling. The fastest way of traveling is by plane. With a modern airliner you can travel in one day to places which it takes a month or more to get to a hundred years ago. Traveling by train is slower than by plane, but it has its advantages. You can see the country when you are traveling through. Modern trains have comfortable seats and dining-cars. They make even the longest journey enjoyable. Some people prefer to travel by sea when possible. There are large liners and 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 traveling by sea is a very pleasant way to spend a holiday. Many people like to travel by car. You can make your own timetable. 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 - where there is something interesting to see, at a good restaurant where you can enjoy a good meat, or at a hotel to spend the night. That is why traveling by car is popular for pleasure trips, while people usually take a train or plane when they are traveling on business.
