龜兔賽跑的英文版故事可以是：
One day, a tortoise named "Slow" challenged a rabbit named "Quick" to a race. The race started at the edge of two forests, and both animals raced at full speed to reach the finishing line.
Quick, with his long legs and speedy strides, took off like a rocket. He could not believe how easily he was ahead of the tortoise. However, he fell into a daze and slept on the ground for a while.
Meanwhile, Slow, who had started slowly but steadily, kept moving forward step by step. When Quick woke up, he saw that the tortoise was already very close to the finishing line. Quick realized that he had been too confident and slept through the race.
Finally, Slow won the race and everyone agreed that patience and perseverance could beat speed and luck in the end.
