世界上许多人知道美国有个黄石国家公园,那里的山情野趣让人留连,然而往往不知道它所在的怀俄明州。 怀俄明面积25.33万平方公里,大约相当于中国浙江、安徽两省之和,人口却只有46.5万人。在这样一个地广人稀的北方州里,主要的经济活动者是畜牧业的牛仔、参观山光水色的游客,以及它的煤矿业。 Many in the world know that the United States has a Yellowstone National Park, where the joys and sorrows make people linger, but often do not know where Wyoming lives. Wyoming, with an area of ​​253,300 square kilometers, is roughly equivalent to the sum of the two provinces of Zhejiang and Anhui in China, with a population of 465,000. In such a sparsely populated northern state, the major economic activists are cowboys in livestock husbandry, tourists visiting mountains and waters, and its coal mining industry.
