参考答案：随着世界上人口的迅速增加，地球上许多野生动物的领地都被城市扩展侵吞。越来越多的人感到在他们住地附近很难看到野生动物，因此强烈要求建造更多的动物园。迪斯尼动物王国是美国最有名的动物园之一。这座占地167公顷的动物园让游客穿越印第安丛林或乘车横跨“非洲平原”。动物在自然环境里漫步，让游客一睹它们的野外生活。
全世界几乎所有的国家都有动物园。在新加坡，夜间动物园每晚七点向游客开放，这个动物园使游客获得观看野生动物夜生活的独特经历。这里大多数动物都在夜间活动，所以园区每天晚上只开放五个小时。随着世界范围的经济扩张和城市化，世界上将没有真正的荒野。随着野生动物变得更加稀少，想看野生动物的游客会更多。但是单靠旅游业不可能保护世界上的野生动物。

With the rapid growth of world population quite a number of wild life reserves on the earth have given way to the expansion of urban areas. More and more people find it hard to see wildlife nearby in their locations. That’s why there is a loud cry for the establishment of more animal parks. Disney’s Animal Kingdom is one of America’s most famous animal parks. The 167-hectare park lets guests hike through the Indian jungle or drive through the African plains. The animals roam through out their environments, allowing visitors a look at their life in the wild.
There are animal parks in almost every country of the world. In Singapore, Night Animal Park begins to open to guests at 7 o’clock every night. The park gives guests the unique experience of visiting wildlife in the dark. Most of the park’s animals are nocturnal, so the park is open for only five hours a night. With economic expansion and urbanization across the world, there will be no truly wild places left in the world. As wildlife becomes even rarer, more tourists want to see them. But tourism alone cannot conserve the world’s wild animals.
