It happened in China. The flood destroyed many farms and houses. People had to leave their homes. The PLA troops helped protect millions of people. I think it is important to learn from such disasters. Part 2 Dear neighbours, to prevent wildfires, we should never leave campfires burning. Clear dry leaves from your yard. If you see smoke in the forest, report it immediately. Let’s protect our forests together. A small spark can start a big fire. Part 3 Understanding natural disasters is important because when we know what causes them, we can prepare better. For example, if we know typhoons bring strong winds, we will stay indoors. If we know floods happen after heavy rain, we will move to higher ground. This knowledge can save lives and reduce damage. Everyone should learn about natural disasters. 1 学科网（北京）股份有限公司 $
