books, and sometimes by asking o             people. There are the ways of teaching yourself. If you keep

     Rivers are one of our most important natural resources (自然资源). Many of the world's great cities
are located on rivers, and almost every country has at least one river flowing through it that plays an
important part in the lives of its people.
     Since the beginning of history, people have used rivers for transportation. The longest one in the
United States is the Mississipi. The lifeline of Egypt is Nile. To the people of India, the Ganges is great,
but it is also important for transportation; ships can travel along it for a thousand miles. Other great rivers
are the Congo in Africa and the Mekong in Southeast Asia. The greatest of all for navigation (航海),
however, is the Amazon in Brazil (巴西). It is so wide and so deep that large ships can go about two
thousand miles upon it.
     Besides transportation, rivers give food to eat, water to drink, water for crops, and chances for fun
and recreation for the people who live along their banks. In order to increase the supply of water for
crops, engineers sometimes build a dam (大坝) across a river and let a lake form behind the dam. Then
people can use the water not only to irrigate (灌溉) their fields but also to make electricity for their homes
and industries. However, large cities and industries that are located upon rivers often make problems. As
the cities grow in size and industries increase in number, the water in the rivers becomes polluted
with chemicals and other materials. {people are learning the importance, however, of doing more to keep
their rivers clean if they want to enjoy the benefits (利益) of this natural resource.
