以下是一個英文自然發音的故事：
Once upon a time in a forest, there was a little bird named Robin. He loved to sing and dance and explore the beautiful forest. One day, he found a magical seed that grew into a beautiful tree. As he played and sang beneath the tree, he realized that the tree was teaching him important lessons about nature and life.
The tree taught Robin how to sing higher and more beautifully when the sun came up in the morning. It taught him how to blend in with the environment and survive by eating fruit from its branches. And it taught him about the importance of sharing and cooperation, because birds from all over the forest would come to rest on its branches and sing together.
As Robin grew older, he learned more and more about nature and the importance of balance and harmony. He learned that the forest was not just a place to play and explore, but also a place where all creatures learned and grew together. And so, every day, he would sing and dance beneath the magical tree, teaching others in the forest about the wonders of nature.
