Long ago, a king got two special baby eagles(鹰) as a gift. The king loved them very much. He invited experienced keeper to look after them.
As time passed, the king noticed that both eagles grew big and looked even (amazing) than before. The king hoped to see the eagles fly. However, as the keeper set (they) free, one eagle flew high into the sky while the other flew a few meters before returning to its starting branch(树枝).
The king wanted (know) why. The keeper answered, "This eagle always has this problem. It refuses to fly high." The (two) day, the king told people that anyone who could help the other eagle fly high would get great (prize). Many people came, studied and tried, no one succeeded. The king began to lose hope.
Then one day, something strange happened. The king (see) both eagles flying high in the sky. He couldn't believe his eyes and called the keeper over. The keeper explained that a farmer had made it and then brought him to the king. The king asked the farmer, "How did you do this?" He replied, "I (simple) cut down the branch where the eagle was used to sitting. no branch, it had to fly. And it did very well."
