The Fox and the Grapes(狐狸与葡萄)
Early in the fall, a fox saw ripe grapes in a garden. He wanted to eat them.
He said to himself, “How lucky I am! I've found some nice grapes.” He crept into the garden, and came to the grapes. He jumped up at the grapes, but he could not reach them. He jumped again and again, but in vain.
At last he gave it up, and said to himself, “The grapes are sour. I don't want sour grapes.” And he went away.
