单项选择题
After one migration (迁移) the next comes more easily. New arrivals in America usually want to settle down and work as quickly as they can, but they may well move again sooner or later. American life has always had its element of change, of movement, some say of restlessness, and this is still so now. In some states only one house in five has people living in it who have been there for more than five years.
In this story of constant movement we think at first of the early pioneers journeying westwards, taking a step further the adventure that had brought them or their parents across the Atlantic. Now there is movement, short or long, in every direction. Some leave their homes because changing economic conditions have put them out of work; others (more commonly now) go to better jobs, or move because they have been promoted.
Even now some go without security and full of anxiety; but others, more fortunate, can move in comfort, with a good job and a new home ready for them. Most college graduates, the new meritocracy, have studied away from home, and see movement as a condition and as one of the symbols of success in life to which they almost automatically aspire (渴望).
