拓展提高（课内同源 + 课外同源）

Passage1（课内同源：三峡大坝如何防洪）

　　The Three Gorges Dam stands on the Yangtze River in Hubei. It is one of the largest dams in the world, and it is more than two kilometres long. People built it to control the river and to make electricity for many cities.

　　The river is very wide and strong in summer. Heavy rain often falls in the mountains, and the water rises quickly. When the water level is high, the dam stores water behind its big wall. Then the gates open slowly, and the water goes down the river in a safe way.
