TRAVELLING Travelling became a part of our life. Thousands of people travel every day either on business or for pleasure. They travel by by train, by air or by sea. Of course, travelling by air is the fastest and the most convenient way, but it is the most expensive, too. Travelling by train is slower than travelling by plane, but it is less expensive. You can see many interesting places of the country through the window. Modern trains have more comfortable seats. There are also sleeping cars and dining cars that make even the longest journey more pleasant, Speed, comfort and safety are the main advantages of trains and planes. That is why many people prefer them to all other kinds of travelling. Travelling by sea is popular mostly for pleasure trips. Tourists can make voyages on large ships to foreign countries. The trips on the Volga, the Don the Black Sea are very popular today. As for me I prefer travelling by car. I think it's more convenient because you don't buy tickets, you can stop any place and spend as much time as you like at any place.
