Tortoise and Rabbit Race (fable)

Tortoise and Rabbit Race is an intriguing fable in which a proud rabbit and a persistent little turtle are portrayed.

One day, the rabbit and the tortoise competed for running. The rabbit laughed at the tortoise's slow climbing, and the tortoise said that he would win one day. The rabbit said, let's start the game now. The rabbit ran quickly, and the tortoise crawled desperately. Soon, rabbit and the tortoise was far away. The rabbit thinks that the game is too easy. It needs to sleep for a while first, and thinks that even if it wakes up, the tortoise may not catch up with it. The tortoise, on the other hand, kept crawling. When the rabbit woke up, the tortoise had reached the finish line. This story tells everyone: don't underestimate others easily. Modesty makes people progress, while pride makes people lag behind. Only by doing things in a down-to-earth manner, don't give up halfway, can you succeed.

Translation

The rabbit has four legs. It jumps and runs very fast.

The tortoise has four legs, too. Climb, climb, climb really slowly.

One day, the rabbit met the tortoise, saw the tortoise crawling so slowly, and wanted to tease him, so he smiled and said, "Tortoise, tortoise, let's have a race, shall we?" The tortoise knew that the rabbit was playing a joke on him and stared at a pair of small eyes, ignoring it and not stepping on it. Knowing that the tortoise didn't dare to race with him, the rabbit jumped up and down with his ears open, and made up a folk song to joke him:

Tortoise, tortoise, climb and climb,

go out early to pick flowers;

tortoise, tortoise, go for a walk.

It's still at the door in the evening.

The tortoise got angry and said, "Rabbit, rabbit, don't be clever, let's race!" "

"what? Tortoise, what did you say? "

"Let's have a race."

Hearing this, the rabbit almost burst into laughter: "Tortoise, do you really dare to race with me? Well, let's run from here and see who runs to a big tree at the foot of the mountain over there first. Get ready! One, two, three-"The rabbit spread its legs and ran, really fast, and soon it was far away. He looked back and saw that the tortoise had only climbed a short distance. He thought, It's a big joke that the tortoise dares to race with the rabbit! Me, sleep here and let him climb here. No, let him climb to the front. I caught up with him in three jumps.

"la la la, the victory must be mine!" " The rabbit lay down on the ground, closed his eyelids and really fell asleep. Besides, the tortoise is really slow, but he keeps climbing, climbing, climbing, climbing, and when he climbs to the rabbit, he is exhausted. The rabbit is still sleeping, and the tortoise wants to have a rest, but he knows that the rabbit runs faster than him, and only by persisting in climbing can he win. So he kept climbing, climbing and climbing. It's getting closer and closer to the tree, only a few dozen steps away, a dozen steps away, a few steps away ...............................................................................................................................................

what about the rabbit? He's still sleeping! The rabbit woke up and looked back. Alas, why did the tortoise disappear? Looking forward again, oh, great! The tortoise has climbed under the big tree. The rabbit looked anxious and hurried to catch up, but it was too late. The tortoise had won.

The rabbit runs fast and the tortoise runs slowly. Why did the tortoise win this competition?
