Although the United States cherishes the tradition that it is a nation of small towns and wide open spaces, only one in every eight Americans now lives on a farm. The recent population trend has been a double one, toward both urbanization and suburbanization. Metropolitan areas have grown explosively in the past decade, and nearly half this increase has been in the suburbs. With the rapid growth of cities has come equally rapid decentralization. The flight of Americans from the central city to the suburbs constitutes one of the greatest migrations of modern times; quiet residential sections outside cities have become collections of streets, split-level houses, and shopping centers.
This sudden increase of suburban expansion, however, does not alter the basic fact th
at the United States has become one of the most urban nations on the face of the earth. Census Bureau's( 人口调查局) figures show that the rural population has been shrinking steadily since 1880. When the United States became a nation it had no large cities at all; today some fifty cities have populations of more than 258 000. Large buildings of cities are developing in the area of the East Coast and the east north-central states, on the Pacific and Gulf coasts, and near the shores of the Great Lakes. Some sociologists now regard the entire 600-mile stretch between Boston and Washington D. C. --an area holding a fifth of the country' s population--as one vast city or, as they call it, megalopolis.

[ A ] movement from the central city to rural areas

[ A ] increased in size
[ B ] undergone no change
[ C ] been shrinking steadily
[ D ] become indistinguishable from the suburbs

Unit 6
Clothes play a critical part in the conclusions we reach by providing clues to who people are, who they are not, and who they would like to be. They tell us a good deal about the wearer's back- ground, personality, status, mood, and social outlook.
Since clothes are such an important source of social information, we can use them to influence people's impression of us. Our appearance assumes particular significance in the initial phases of interaction that is likely to occur. An elderly middle-class man or woman may be alienated (疏远) by a young adult who is dressed in an unconventional manner, regardless of the person's education, background, or interests.
