“指定”
用英语怎么说？

Since 1903, the United States has established more than 580 National Wildlife Refuges. The government designated these beautiful lands and waters as protected areas to save plants and animals. Across the country, many different species find a safe home in these places. For example, a heavy bison walks through the Rocky Mountain Arsenal in Colorado, with the Denver skyline visible far behind it. During winter, thousands of white snow geese take flight together in New Mexico, filling the sky. In Virginia, wild ponies drink water and eat grass peacefully. However, these places face some dangers. Recently, several environmental organizations filed lawsuits to stop construction plans. They want to prevent a road from being built through a protected area in Alaska.

自1903年以来，美国已经设立了580多个国家野生动物保护区。政府将这些美丽的土地和水域指定为保护区，以保护植物和动物。在全国各地，许多不同的物种在这些地方找到了安全的家园。例如，一只沉重的野牛穿过科罗拉多州的落基山军械库，丹佛市的天际线在它身后清晰可见。冬季，成千上万只白色的雪雁在新墨西哥州一同起飞，遮天蔽日。在弗吉尼亚州，野生的矮马安静地喝水、吃草。然而，这些地方也面临着一些危险。最近，几个环保组织提起诉讼，以阻止建设规划。他们希望阻止在阿拉斯加的一处保护区内修建道路。
