[单项选择]Passage 2
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
and how tourism affects them. Tourism should help a country to keep the customs
and beauty that attract tourists. Tourism should also advance the well-being 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, first-class roads, and
other support facilities needed by tourist attractions. For example, a major
international-class tourism hotel can cost as much as 50000 dollars per room to
build. If this room is not used most of the time, the owners of the hotel lose
money. Building a hotel is just a beginning. There must be many
support facilities as well, including roads to get to the hotel, electricity,
sewers to handle waste and water. All of these support facilities cost money. If
they are not used because there are not enough tourists, jobs and money are
lost. |
Which of the following has most probably been discussed in the para. that goes before the para. ______.
A. It is extremely important to develop tourism
B. Building roads and hotels are essential
C. Support facilities are highly necessary
D. Planning is of great importance to tourism
