9月27日是世界旅游日。这一节日始于1980年，由联合国世界旅游组织设立，目的在于提高人们对国际旅游业作用的认识。联合国世界旅游组织希望突出旅游业对世界范围内社会、文化和经济的意义。自1997年起，东道主国家作为联合国世界旅游组织的合作伙伴庆祝世界旅游日，每年的主题都不近相同。1980年的第一个主题是旅游业对文化遗产保护、世界和平和相互理解的贡献。其他的主题包括青年旅游、旅游是世界和平的力量、旅游与气候变化。

　　Tourism is one of the biggest industries in the world. It employs millions of people and generates billions of dollars. Many developing countries rely on tourist dollars for their survival. In recent decades tourism has boomed. People are richer, air travel is cheaper and many closed borders are coming down. The collapse of communism has seen millions of new tourists coming out of Russia and the former communist countries. This increase in tourism does create problems. In many of the world's top tourist destinations, there is a strain on the environment. The huge number of tourists is in danger of destroying the reason for sites being so popular. World Tourism Day is a good time to look at our global responsibilities as tourists.

　　旅游业是世界上最大的产业之一。数百万人从事这一行业，创造了数十亿美元的收益。许多发展中国家都依赖旅游收入维持。近十年来，旅游业兴旺起来，原因在于人们变富了，航空旅游更便宜了，许多闭塞的边境开放了。共产主义失败后，数百万游客从俄国和前共产主义国家走出来。游客的增多带来很多问题。在许多世界顶级的旅游胜地，生态环境不堪重负。因一些景点特受欢迎，大量游客的到来造成景点的破坏。世界旅游节是反思游客国际责任的好时候。
