The Family
The structure of a family takes different forms around the world and even in the same society.The family's form changes as it adapts to changing social and economic influences.
Until recently,the most common form in North America was the nuclear family,consisting of a married couple with their minor children.The nuclear family is an independent unit,It must be prepared to fend for itself.Individual family members strongly depend on one another.There is little help from outside the family in emergencies.Elderly relatives of a nuclear family are cared for only if it is possible for the family to do so.In North America,the elderly often do not live with the family；they live in retirement communities and nursing homes.
There are many parallels between the nuclear family in industrial societies,such as
North America,and of families in societies such as that of the Inuits,who live in harsh environments.The nuclear family structure is well adapted to a life of mobility.In harsh conditions,mobility allows the family to hunt for food.For North Americans,the hunt for jobs and improved social status also requires mobility.
The nuclear family was not always the North American standard.In a more agrarian time,the small nuclear family was usually part of a larger extended family.This might have included grandparents,mother and father,brothers and sisters,uncles,aunts,and cousins.
In North America today,there is a dramatic rise in the number of single-parent households.
Twice as many households in the United States are headed by divorced,separated,or nevermarried individuals as are comprised of nuclear families.The structure of the family,not just in North America,but throughout the world,continues to change as it adapts to changing conditions.

[单项选择]Too often young people get themselves employed quite by accident, not knowing what lies in the way of opportunity for promotion, happiness and security. As a result, they are employed doing jobs that afford them little or no satisfaction. Our school leavers face so much competition that they seldom care what they do as long as they can earn a living. Some stay long at a job and learn to like it; others quit from one to another looking for something to suit them. The young graduates who leave the university look for jobs that offer a salary up to their expectation. Very few go out into the world knowing exactly what they want and realizing their own abilities. The reason behind all this confusion is that there never has been a proper vocational guidance in our educational institution. Nearly all grope in the dark and their chief concern when they look for a job is to ask what salary is like. They never bother to think whether they are suited for the job or, even more important, whether
