　　One hot summer day a fox was walking through an orchard. He stopped before a bunch of grapes. They were ripe and juicy.

　　"I'm just feeling thirsty," he thought. So he backed up a few paces, got a running start, jumped up, but could not reach the grapes.

　　He walked back. One, two, three, he jumped up again, but still, he missed the grapes.

　　The fox tried again and again, but never succeeded. At last he decided to give it up.

　　He walked away with his nose in the air, and said“I am sure they are sour.”
