大楼内的新型运载工具
At the end of the story Charlie and the Chocolate Factory by Roald Dahl, the eccentric inventor and candy – maker Willy Wonka takes young Charlie Bucket into a glass contraption that he calls a Wonkavator. It bursts through the roof of the factory and flies them out over the city. Willy Wonka says, An elevator can only go up and down, but the Wonkavator can go sideways, and slantways, and longways, and backways, and squareways, and frontways, and any other ways that you can think of.
