From the article we can come to the conclusion that professional travel will not______.

Generally there are two types of tour guides, one in charge of local sightseeing and the other accompanying a group throughout its travels and making all the arrangements for the group. In China, they are usually known as local guide and national guide. The sightseeing guide must be familiar with the points of interest that he is showing to the visitors. He usually gives prepared talk but he must also be prepared to answer a lot of questions. And of course he has to deal with any problems that occur during the tour. These may include bad weather, sudden illness, an accident and so on. It would be impossible to name everything that might happen. A sightseeing guide needs two qualities—an outgoing personality and language skill.

旅游业对环境的影响

In general, the world's developed nations, owing to the advanced development of their economies and scientific technology, have experienced high levels of tourism demand and supply. Tourist facilities and services have been expanded and developed around the world to meet the rising demand of travelers from developed countries. But, the unbalanced levels of economic growth among different countries have led to disparities in tourism development. In developing countries, the low level of economic livelihood restricts the development of a domestic tourism industry. This is true even in those countries with a strong international tourism sector. Most of the people in the developing world are still struggling to make ends meet. Thus, leisure travel for them remains a distant dream.
