三、八(3)班以“自然对人类的贡献”为主题，搜集了关于河流对人类的贡献的资料。阅读下面短文，选出最佳选项。
Rivers are very important for people and nature. Many big cities are next to rivers. That's because rivers play an important part in the lives of people.
For a very long time, people used rivers to transport goods and to travel. The longest river in the United States is the Mississippi River. The most important river in Egypt is the Nile River. To the people of India, the Ganges is great. Ships can travel along it for a thousand miles. Other great rivers are the Congo River in Africa and the Mekong River in Southeast Asia. The greatest of all for navigation(航海) is the Amazon River in Brazil. It is so wide and so deep that large ships can go about two thousand miles upon it.
Besides, rivers give food, water to drink, water for crops, and chances for fun for the people who live along their banks. Sometimes people build a big wall called a dam(大坝) across a river. This makes a lake behind the wall. People can then use this water for two things—to give water to plants on farms and to make electricity for houses and factories.
But there is a problem. Big cities and factories are often near rivers. When cities get bigger and there are more factories, the river water can get dirty. Bad things like chemicals go into the water.
People are learning that they must keep rivers clean. If rivers are clean, people can keep using them and getting all the good things from them. Rivers are a very important natural thing we need to take care of.
