The city zoo bought a new kangaroo(袋鼠) from Australia. It was famous for jumping very high. A zoo keeper was worried that the kangaroo would run away. He built special walls around it. But the next morning, people found that the animal was playing around outside. So the zoo keeper made the height of the walls 5 metres. But the kangaroo got out again the following day. The zoo keeper felt very angry, so he made the walls as high as 10 metres, but the kangaroo still got out.

“How high do you think he’ll keep on building the walls?” a giraffe asked the kangaroo. “I don’t know,” said the kangaroo. “Maybe they’ll reach 300 metres. But it isn’t important to me. I can still go out of the zoo if the zoo keeper doesn’t remember to close the door.”
