为什么旅游业的三大支柱是旅行社、餐饮、交通，而不是酒店、餐饮、交通？？？

Tourism, a smokeless industry, is developing rapidly in China. With the reform and opening –up policy being carried out,thousands upon thousands of foreign visitors are crowding into our country. They are eager to see this old mysterious land with asplendid culture of more than 5, 000 years. Tourism as a form of enterprise brings China a lot of benefits. In the fires place, it is financially beneficial to the economicdevelopment of China. As our know, China needs more and more foreign currencies for its modernization program. Tourism is one ofthe most important channels to obtain currencies. Secondly, tourism enables the Chinese people to know more about the outsideworld. On the other hand, the foreigners who have visited China are deeply impressed by the latest developments of out country and thefriendliness and hospitality of our people. Reports by visitors to China about how courteous and helpful most Chinese were to them areoften printed in newspapers of many different countries. It is clear that tourism contributes a great deal to the friendship and mutualunderstanding between the Chinese people and people all over the world. Everything, however, has two sides. Tourism gives rise to a number of problems. For instance, it becomes a burden to ourinefficient transportation system. Besides, the living standard of the average Chinese is still not high enough to be able to afford themany different sorts of expenses during long distance travels. Therefore, there are still a lot of obstacles hindering the expansion oftourism in our country. As for me, with the developme ent of our national economy, all these problems will certainly be solved step by step. A much betterand brighter future awaits us. 译文旅游业----“无烟的工业”----正在中国迅速发展。随着改革开放政策的贯彻执行， 数以万计的外国游人涌入中国。他们渴望参观这个具有5000
