On sunny days, people feel happy. On rainy days, people may feel sad. Birds don’t sing much on windy days. Plants die if it is too cold. Farmers have to worry about too much or too little rain. So weather really matters to all living things. Part 2 We can’t change the weather, but we can prepare for it. During a big storm, we should stay at home. Schools may have to close. In thick fog, drivers have to drive slowly. On very hot days, we should drink more water and stay in the shade. On snowy days, we can wear warm clothes and boots. Being prepared keeps us safe. Part 3 Last summer, there was a big storm in my city. It rained heavily for three hours. The wind was very strong. People had to stay inside. Some trees fell down on the road. My family and I stayed at home and watched the news. After the storm, we went outside and saw many branches on the ground. It was scary but also exciting. I learned that we should always check the weather forecast before going out. 1 学科网（北京）股份有限公司 $
