Tourism wasn’t as important as it is today. In the past, only people with a good deal of money could travel on holidays to other countries. More people travel today than in the past because there is a growing middle class in many parts of the world; that is to say, people now have more money for travel. Special plane fares(费用) for tourists make travel less expensive and more attractive than ever before. One person doesn’t travel for the same reason as another. But most people enjoy seeing countries that are different from their own. They also like to meet new people and to taste new food.

Tourism causes many changes in a country and in people’s lives. People build new hotels and restaurants and train native men and women as guides to show visitors interesting places. There’re new nightclubs and other amusements. International tourism is clearly a big business.
