32、 a generation gap, a division between young people and their elders. Parents complained that children did not show them proper respect and obedience, while children complained that their parents did not understand them at all. What had gone wrong? Why had the generation gap suddenly appeared? Actual

33、ly, the generation gap bas been around for a long time.

34、e expected to live in the same area as their parents, to marry people that their parents know and approve of, and often to continue the family occupation. In our society, young people often travel great distances for their educations, move out of the family home at an early age, marry or live with p

35、eople whom their parents have never met, and choose occupations different from those of their parents.In our upwardly mobile society, parents often expect their children to do better than they did: to find better jobs, to make more money, and to do all the things that they were unable to do. Often,

36、however, the ambitions that parents have for their children are another cause of the division between them. Often, they discover that they have very little in common with each other.Finally, the speed at which changes take place in our society is another cause of the gap between the generations. In

37、a traditional culture, elderly people are valued for their wisdom, but in our society the knowledge of a lifetime may become obsolete overnight. The young and the old seem to live in two very different worlds, separated by different skills and abilities.No doubt, the generation gap will continue to

42、neration should value the older generation for their wisdom.C.The generation gap is partly created by the elder generation.D.The generation gap should be avoidable in American society.大学英语四级综合-48 答案解析(总分：180.00，做题时间：90 分钟)一、Unit 2(总题数：4，分数：180.00)Passage OneThe black robin(知更鸟) is one of the worlds
