    Hundreds of years ago there lived a king in a small country. He liked swimming. When summer came,

he always went to another palace by a forest with his guards and returned to the capital in autumn.

    One afternoon the king went swimming in a river in the forest but he didn't tell others about it. He was

very happy when he swam in the water. After that he heard a great noise and saw a big bear coming at

him. He tried his best to run away. He ran and ran and at last he lost his way. He was hungry and tired

when he found an old house. There was an old farmer in it. "It's your king," he said to the old man. "I'm

hungry now. Bring me something to eat quickly!"
