在非洲有个国家修建了一个规模庞大而又别具一格的动物园。在这个动物园中,各种动物在天然环境中生活,悠然自得,而游客则被关进了活动的笼子——封闭的汽车中进行浏览,可大饱眼福。于是“笼子的内部变成了外部,而外部则成了内部”,可谓放虎归山,引人“入笼”, A country in Africa has built a large and unique zoo. In this zoo, animals of all types live in natural surroundings and enjoy themselves in a leisurely manner, while visitors are locked into the cage of activity—in closed cars, to browse and enjoy. As a result, “the inside of the cage became external, and the outside became internal,” and it can be said to let the tiger return to the mountain and attract people to “enter the cage”.
