                                                                     Travel and Life

     Millions of people all over the world spend their holidays travelling. They travel to see other countries and

continents, modern cities and the ruins of ancient tombs; they travel to enjoy particular places, or just for a

change of scene. It's always interesting to discover new things, different ways of life, to meet different people,

to try different food and to listen to different music.

     Those who live in the country like to go to a big city and spend their time visiting museums and art galleries

(艺术馆), looking at shop windows and dining at exotic (异国情调的) restaurants. City dwellers usually like a

quiet holiday by the sea or in the mountains, with nothing to do but walk, bathe and laze in the sun.

     Most travellers and holiday-makers take a camera with them and take pictures of everything that interests

them-the sights of a city, old churches and castles, views of mountains, lakes, valleys, plains, waterfalls, forests,

different kinds of trees, flowers and plants, animals and birds. Later, perhaps years later, they will be reminded

by the photos of the happy time they have had.

     People travel by train, by plane, by boat and by car. All means of travel have their advantages and

disadvantages. And people choose one according to their plans and destinations.

     If we are fond of travelling, we will see and learn a lot of things that we can never see or learn at home,

though we may read about them in books and newspapers, and pictures of them on TV. The best way to study

geography is to travel, and the best way to get to know and understand people is to meet them in their own

homes.
