快乐植树节，我们一起种树啦！
Today is March 12th. It’s Arbor Day — a day to plant trees. Our school has a tree-planting activity. My classmates and I go to the school yard. First, we dig holes with small shovels (铁锹). Then we put the small trees into the holes. We cover (覆盖) the roots with soil (土壤). After that, we water the trees. Our teacher helps us, too. We are all very happy. I hope the trees will grow tall and strong. What a great day!
