动物笑话|Kangaroos and the Cage 袋鼠与笼子

One day the staff members of a zoo called a meeting to discuss the problem--how to deal with the kangaroos that were found out of the cage. They came to the conclusion that the cage was placed too low and decided^{1 to raise it from one to two meters high. But the next day the kangaroos were still at large（详尽的，未被捕的） and they again raised the cage to three meters.}

Quite beyond their expectation the next morning they saw the kangaroos still free to go about（着手做，四处走动） . They were alarmed and determined^{2 to go to all the length by raising the cage to the height of ten meters.}

Later a giraffe（长颈鹿） , while chatting with some kangaroos, asked them, Do you think they will go on raising your cage?

Hard to say, said a kangaroo, if they continue forgetting to fasten the cage door.
