大家帮看看这个dynamic quality 在这里啥意思。。。

wxylwy

The changing physical landscape reflected the

 shift to an urbanized society.  Railroad terminals,

 factories, skyscrapers, apartment houses, streetcars,

 electric engines, department stores,

 and the increased pace of life were all signs of

 an emerging urban America.  Indeed, the vitality,

 dynamic quality, variety, and restless experimentalism

 in society centered in the urban communities where the

 only constant factor was change itself.

还有这个restless experimentalism 多谢了。。。

 In 1860 the United States was predominantly rural.

 Most people were engaged in agriculture, and about

 80 percent of the population actually resided on farms

 or in small villages.  Only 20 percent lived in towns

 and cities of 2,500 or more, the census definition of

 an urban area after 1880.  New York alone in 1860

 had more than 1 million people, and only 8 cities

 could boast about a population of more than

 100,000.  Thereafter the transition from a rural to a

 predominantly urban nation was especially remarkable

 because of its speed.  By 1900 urbanization, with all of

 its benefits, problems, and prospects for a fuller life,

 became the mark of modern America.

    The changing physical landscape reflected the

 shift to an urbanized society.  Railroad terminals,

 factories, skyscrapers, apartment houses, streetcars,

 electric engines, department stores,

 and the increased pace of life were all signs of

 an emerging urban America.  Indeed, the vitality,

 dynamic quality, variety, and restless experimentalism

 in society centered in the urban communities where the

 only constant factor was change itself.

    Urbanization did not proceed uniformly throughout

 the nation.  New England and the Middle Atlantic states

 contained the highest percentage of city dwellers.  In

 the Middle West, the growth of cities such as Chicago,

 Milwaukee, Cleveland, and St. Louis showed the

 importance of urbanization in that region.  The three

 West Coast states also experienced rapid urban

 growth.  In the South, urbanization developed much

 more slowly, although by 1910 the expansion of transpo-

 rtation, commerce, and industry had greatly

 increased the population of older cities such as

 New Orleans and stimulated the growth of new urban

 centers such as Birmingham.  However, the South

 remained predominantly rural.  Only somewhat more

 than 20 percent of the population in that region was

 urban by 1910.

    In some regions the urban impact had a

 depressing effect upon the surrounding rural

 communities.  Much of New England in the late

 nineteenth century presented a discouraging picture

 of abandoned farms and sickly villages as people

 forsook the countryside and rushed to the larger towns

 and cities.  In the Middle West, particularly

 Ohio and Illinois, hundreds of townships lost

 population in the 1880's.

说的是动起来的质量，其实就是说交通质量的提高。
