Students can travel in the United States without spending too much money if they follow these suggestions.

A travel agent can give you information on special economy fares for trains, buses and planes. Think about hiking or biking for a part of your trip, too. You’ll not only save money, but you’ll also see a lot more of the country.

Some students may want to travel by car. Be sure to think about going with other students—many colleges have “ride boards” that list when and where other students plan to travel. Many radio stations provide the same sort of service — they announce who’s driving where, when, how many riders they will take and what the expenses will be.

There are many inexpensive, older hotels near bus or train stations. Check your travel guide for names of the best. Many parts of the country also have youth hostels where young people can stay for only a few dollars a night.

You don’t have to eat in restaurants all the time, but we don’t recommend a diet of candy and cola, either. You can usually get a healthy, cheap breakfast in a restaurant. If the weather is warm, you can buy food in supermarkets or at roadside stands and have a picnic for lunch. For dinner you can get the names of good, cheap restaurants from travel guides or friends.

Threes are useful to man in three very important ways: they provide him wood and other products; they give him shade; and they help to prevent drought (干旱) and floods. Unfortunately, in many parts of the world, man bas 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. 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 pieced, the 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. 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 no 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. Trees are useful to man mainly in three ways, the most important of which is that they can __________ . A.
