Nowadays travelling is a popular activity among people. It is very interesting to see new places, another towns and countries. People like travelling and they travel a lot. They can travel for pleasure or on business. 
There are different methods of travelling. You can travel by plane, by ship, by train or by car. Some people travel on foot.  You can go along little lanes where the fast car can’t go. You can wander through meadows, pass quite lakes and wonderful woods. Also you can see wild animals and flowers in the forest. You can feel the beauty of nature.  But I think, it’s not a very comfortable way of traveling, because you can get tired very quickly.

I’m very fond of travelling and I prefer to travel by train. I think it’s very pleasant. Especially if you have a comfortable seat in a railway carriage you can have a splendid view of the countryside. If the journey is long, you can sleep and have a good rest. Moreover, I consider, big railway stations are quite excited places. There are crowds of people, the porters pull the luggage along the platforms, and hungry passengers hurry to the refreshment rooms.

Some people prefer to travel by plane. I can say it is, of course, comfortable and convenient method of travelling. And it is much quicker than any other method, but, I think, it’s more dangerous. Moreover nowadays there are a lot of accidents and plane wrecks.

For a change you can travel by ship. During such voyage you can enjoy the sea or the ocean. It’s very exciting to watch the rise and fall of waves, to feel the fresh wind and hear the cry of the seagulls. But everything will be pleasant on board if you are not sea-sick.

Tours by car are also very popular. The main advantage of this method is that you are quite independent. You don’t have to watch a timetable or buy any tickets. You can stop at any place you like and see sights at a short time. And you can drive in any direction.

I think that if you go abroad you should know foreign languages, because they can help you to communicate with people in a foreign country, and you will feel more comfortable.
