Without proper planning, tourism can cause problems. For ex ample, 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 a bout 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 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.
(78)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 50 thousand 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 sup- port 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.
6. Which of the following has most probably been discussed in' the former paragraph of this passage？
A. it is extremely important to develop tourism.
B. Building roads and hotels is essential
C. Support facilities are highly necessary
D. Planning is of great importance to tourism
(79)Trees are useful to man in three very important ways: they provide him wood and other products, they give him shaded and they help to prevent drought and floods.
Unfortunately, in many parts of the world, man has not realized that the third of these services is the most important. In his eagerness to draw quick profit from the trees, he has cut them down in large numbers, only to find that with them he has lost the friends he had.
Two thousand years ago, a rich and powerful country cut down its trees to build warships, with which to gain itself an empire. It gained the empire but, without its trees, its soil became bare and poor. When the empire fell to pieces, the home country found itself faced by floods and starvation.
Even where a government realizes the importance of a plentiful supply of trees, it is difficult sometimes to make the people realize this. They cut down the trees but are too careless to plant and look after new trees. (80)So, unless the government has a good system of control, or can educate the people, the forests slowly disappear.
This does not only mean that there will be fewer trees. The results are even more serious: for where there are trees, their roots break the soil up, allowing the rain to sink in, and also bind the soil. This prevents the soil from being washed away. But where there are on trees, the rain falls on hard ground and flows away on the surface, and this causes floods and the rain carries away the rich topsoil in which crops grow. When all the topsoil is gone, nothing remains but worthless desert.
11. According to the passage, trees are useful to man mainly in three ways, the most important of which is that they can ______
A. keep him from the hot sunshine
B. prevent him from floods
C. make him draw quick profit from them
D. help him to keep from the attack of drought and floods
