阅读下面的短文,然后按要求写一篇150字左右的英语短文。

A boy found an eagle’s egg and he put it in the nest of a hen. The eagle hatched and thought he was a chicken. He grew up doing what chickens do—scratching for food and flying short distances. It was a dull life. Gradually the eagle grew older and biller. One day he and his chicken friends saw a beautiful bird soaring on the currents of air, high above the mountains.

“Oh, I wish I could fly like that!” said the eagle. The chicken replied, “Don’t give it another thought. That’s the mighty(强大的) eagle, the king of all birds—you could never be like him!” And the eagle didn’t give it another thought. He went on cackling and complaining about life. He died thinking he was a chicken.

My friends, you too were born an eagle. The Creator intended you to be an eagle, so don't listen to the chickens!
