论１９世纪美国政府在西部开发中的作用

在１９世纪美国社会发展的过程中，尤为引人注目的是政府对西部的开发，美国的西部与我国西部面积相当，１９世纪初尚是一片荒凉的地域，当时的美国还是世界上的弱国，然而，美国用不到一个世纪的时间完成西部的开发，改变了社会面貌，为美国发展成为经济强国奠定了基础，政府为开发西部所采取的出售土地、发展交通、鼓励移民等措施，对今天我国西部开发仍具有借鉴的意义。

On the Functions of American Government in the Exploitation of the West During the 19th Century

In the development of American society during the 19th century,it was especially noticeable that the American government exploited the west.The American west is almost as large as China's in area.It was a wild and uncultivated land and the United States was a weak nation in the world then.However,the exploitation of the west was accomplished in less than a hundred years.It greatly changed the features of American society and laid a foundation for the United States to develop into an economic power.The ways taken by the American government to exploit the west ,such as to sell land,develop communications,promote immigrants and so on,are still meaningful for the exploitation of Chinese west.
