  • 题型描述: 阅读理解With the steady increase in the amount of leisure time that people enjoy today, the importance of businesses that deal with leisure products and services is also steadily increasing. Among them, tourist industry is one of the biggest industries of this kind. Providing transportation and accommodations for tourists — and guides, brochures, souvenirs — is one of the major industries in many countries. Since people are now having longer vacations and are more and more interested in seeing other parts of the world, this business will no doubt continue to grow.

Professional sports make money because people pay to watch them in their free time. This list could be greatly extended. But even among these industries, we have mentioned only part of the picture.
