The Third Race Between the Rabbit and the Tortoise

We all know the tortoise beat the rabbit in the first race.

Then they had a second race, and the rabbit beat the tortoise. Yesterday they had the third race. The rabbit ran fast as soon as the starting gun went off, and it ran much faster than the tortoise. Suddenly, the rabbit’s feet hurt so badly that he had to stop running. The tortoise found that, and then he carried the rabbit on the back without saying a word. At last, they reached the finishing line at the same time. After the race the rabbit said thankfully to the tortoise, “Thank you very much. The meaning of the winner this time is special for me. I won’t be the winner unless you help me.”

I think the tortoise is great. He helped the rabbit although they were in a race.
