参考范文：
It’s spring. It’s time to plant trees.
I want to plant a tree in our garden. Dad and Mum are very happy. They like green. Dad helps me plant the tree. First, we dig the soil. Then I put a little tree into the soil. Next I water it. I am so excited and I wait for the tree to grow. Two weeks later, my tree has some little leaves. I water it every day. Now it has lots of leaves. It grows fast. We should plant more trees. They make our world beautiful.
