     All big cities are quite similar (相似的). Living in a modern Asian city is not very different from living in

an American city.But it is different from living on farms, however.

     In many parts of the world, farmers and their families live in villages or towns. In the United States,

however, each family lives on its own fields, and often can't see any neighbor. Instead of traveling from a

village to the fields every morning. American farmers stay on their land all the week. They travel to the nearest

town on Saturdays for shopping or on Sundays for church. The children ride on horses to large schools which

serve all of the farm families living in the area. In some areas, there are some small schools serving a few

families, and the children walk to school. 

     Of course, life keeps changing for everyone, including farmers. Today, there are cars, good roads, radios

and television sets. And of course there are modern machines for faming. All of this have changed farm life. 

     For many years, however, farming in America was often a lonely way of living.Farmers had to deal with

their own problems,instead of getting help from others. They learned to try new ways and to believe their

ideas instead of following old ways.
