First, we dug a large hole. Then, we placed the seedling inside and covered its roots with soil. Finally, we pressed down on the soil and watered it. I learned that trees need care to grow well. It was fun because I worked with my classmates. Part 2 Dear Mum and Dad, may I join the tree planting activity on March 12? Our school is planning to plant trees in the city park. The activity will be held on Tree Planting Day. I will follow the steps: dig, place, cover, press and water. Please let me go because I want to help protect the environment. I promise to be safe and careful. Part 3 Planting trees is important because trees can protect the soil from rainfall. They also prevent dust from spreading and make the air cleaner. Without trees, the desert may grow larger and swallow grasslands. Trees help keep the water cycle balanced. We should plant more trees to build a green wall against dust storms. 1 学科网（北京）股份有限公司 $
