Last summer, a strong typhoon hit my city. The wind blew heavily and many trees fell down. At that time, we were all staying safely at home. It is important for us to learn how to protect ourselves. Before a disaster, we should learn more safety knowledge and get things ready. When it is happening, we must keep calm, stay away from dangerous places and never go out easily. After the disaster, we need to help each other and clean up our neighborhood together. Nature is powerful. If we learn to be well-prepared, we can live safely and peacefully with nature. 学科网（北京）股份有限公司 $
