Harris was a very small hare(野兔) with very big feet. "Why do I have such big feet, Grandpa?" Harris asked. "All hares have big feet, Harris. I will show you 1 ," said Grandpa.

Grandpa hopped(单脚跳) 2 into the air. Harris copied(模仿) it. He kept practicing over and over again until he could hop as high 3 Grandpa. Then Grandpa took Harris up to the 4 of the mountains. He told Harris, "With your big feet, you can hop to the top of your world."

Grandpa taught Harris lots of life 5 . For example, he taught Harris how to 6 a cool resting place in the earth when the days were hot. One summer afternoon, they stopped to 7 the grass. Harris shouted happily, "Look, Grandpa! My feet can 8 me away from the hot sun! I'm so 9 to have such big feet." As time went by, he got to know the10 of his feet.

One day Grandpa noticed a wolf looking closely at them from a distance (从远处). He kept cool and spoke 11 to Harris, "The most important thing about your big feet is they can 12 you to run very fast." Harris began to run and didn't stop 13 he heard the howl (嚎叫) of the wolf. "Grandpa, why aren't you running with me?" Harris ran back and 14 sadly.

"Little Harris, I'm growing old. It's time for you to learn to live in 15 own world."

Harris kept Grandpa's words in mind and he believed his big feet would take him to the end of the world.
