It is located in China on the Changjiang River. It works by holding back excess water during heavy rains and releasing it slowly. It is important because it protects millions of people from floods. Without it, many cities would be in danger. Part 2 Dear local government, to prevent floods, I suggest we build more dams and clean the rivers. For example, we can plant more trees on the hills to stop soil from washing away. We should also warn people not to build houses near riverbanks. It is important to act before a flood happens. Thank you for your attention. Part 3 Preventing floods is more important than responding to them because prevention saves lives and money. If we prevent them, we can avoid the destruction of homes and farms. For example, the Three Gorges Dam has protected millions of people. Without prevention, people would suffer every time it rains heavily. Therefore, we should invest in flood prevention projects. 1 学科网（北京）股份有限公司 $
