One day, a monkey and a turtle ran a race. “I am big, I can run fast. I will win,” the monkey said. “I am small. I am slow. But I will do my best,” the turtle said. The monkey ran faster than the turtle. Then the monkey’s friend, the rabbit came out. The rabbit said to the monkey, “let’s play!” The monkey thought he would win anyway. So he played with the rabbit. The turtle ran slowly. But he ran and ran. Finally the turtle won. The turtle shouted, “I won!” The monkey was still playing with the rabbit. Then the monkey found the turtle. He was very surprised. But it was too late.
