Once a little weed（杂草）grew in a field. There were many tall and beautiful flowers around it. Lots of bees and butterflies came to them because of their nice smells and bright colours. The little weed wasn't satisfied, because its flowers were tiny and simple.
One spring morning, three children came to play in the field. "Let's pick some flowers for our grandma!" said one. "That's a good idea!" said another. "She will love all these bright and beautiful flowers!"
"What about that one?" the youngest child said, pointing at the little weed. "Forget it!" laughed the oldest brother. "That's just a useless weed!"
Hearing this, the little weed felt even worse. "Am I really useless?" it asked itself. "Why was I put on the Earth?"
In winter, all flowers were gone, only the little weed stood alone in the field. Just at that time, it noticed some birds coming above the field. "We are hungry!" they shouted. The little weed felt sorry for the poor birds and called out to them, "Hey! Down here! I have pods（豆荚）that you can eat!"
"You're so kind!" The birds ate up the seeds（种子）in the pods thankfully. "They're delicious. We can't find anything better than what you gave us!"
This made the little weed pleased and confident. "At last, I have found out what I am good for!" the little weed said.
