The position of children in American family and society is no longer what is used to be. The 1 family in colonial(殖民时期的) North America was mainly concerned with survival and2that, its own economic prosperity. Thus, children were 3in terms of their productivity(生产能力), and they played the role of producer quite early.4they fulfilled this role, their position in the family was one of subordination(附属).
With the 5 of the society, the position of children in the family and in the society became more important. In the complex and technological society 6the United States has become, each 7 must fulfill a number of personal and occupational8 and be in contact with many other member. 9, viewing children as necessary members of society means that they are 10 more as people in their own right than as those of subordination. This acceptance of children as11 participants in the family is reflected in various laws 12 the rights of children and in the social and public welfare programs.
This new 13of children and the frequent contact between the members of society has also 14an increasing interest in child-raising techniques. People today spend much time15 the proper way to 16 children.
Nowadays, the socialization of the child in the United States is a 17transaction(事务) between parent and child18a one-way, parent-to-child training19 . As a consequence, socializing children and20with them over a long period of time is for parents a mixture of pleasure, satisfaction, and problems.
