　　阅读理解, 从给的四个选项 (A、B、C和D) 中, 选出最佳选项。

　　Without proper planning, tourism can cause problems. For example, too many tourists can crowd public places that are also enjoyed by the inhabitants of a country. If tourists create too much traffic, the inhabitants become annoyed and unhappy. They begin to dislike tourists and to treat them impolitely. They forget how much tourism can help the country's economy. It is important to think about the people of a destination country and how tourism affects them. Tourism should help a country, keep the customs and beauty that attract tourists. Tourism should also advance the wealth and happiness of local inhabitants.

　　Too much tourism can be a problem. If tourism grows too quickly, people must leave other jobs to work in the tourism industry. This means that other parts of the country's economy can suffer.

　　On the other hand, if there is not enough tourism, people can lose jobs. Businesses can also lose money. It costs a great deal of money to build large hotels, airports, air terminals, first­class roads, and other support facilities(配套设施)needed by tourist attractions. For example, a major international class tourism hotel can cost as much as 50 thousand dollars per room to build. If this room is not used most of the time, the owners of the hotel lose money.
