Unit 1 Task 6

【原文】 The American family unit is in the process of change. There used to be mainly two types of families: the extended and the nuclear. The extended family most often included mother, father, children, and some other relatives, such as grandparents, living in the same house or nearby. Then as job patterns changed and the economy progressed from agricultural to industrial, people were forced to move to different parts of the country for job opportunities. These moves split up the extended family. The nuclear family became more prevalent; this consisted of only the parents and the children. Now besides these two types of traditional groupings, the word "family" is being expanded to include a variety of other living arrangements. Today's family can be made up of diverse combinations. With the divorce rate nearly one in two, there is an increase in single parent homes: a father or mother living with one or more children. "Blended families" occur when previously married men and women marry again and combine the children from former marriages into a new family. On the other hand, some couples are deciding not to have any children at all, so there is an increase in childless families. There are also more people who live alone: single, widowed, divorced. Now one in five Americans lives alone.
