Geography
Americans often speak of their country as one of several large regions. These regions are cultural units rather than governmental units - formed by history and geography and shaped by the economics, literature and folkways(民俗) that all the parts of a
region share.
What makes one region different from another? Within several regions, language is used differently and there are strong dialects(方言). There are also differences in
outlook and attitude based on geography. A region's multicultural heritage as well as distinct demographic characteristics like age and occupation also make regions different and special.
The United States is a varied land - of forests, deserts, mountains, high flat lands and fertile plains. The country lies mostly in the temperate zone but there is a very wide range of climate variations.
