One important cause of the generation gap is the opportunity that young people have to choose their own ways of life.In a more traditional society, when children grow up, they are expected to live in the same area as their parents, to marry people that their parents know and like, and often to continue the family jobs.In our society, young people often travel great distances for their education, move out of the family at an early age, marry or live with people whom their parents have never met, and choose jobs different from those of their parents. In our 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, that is another cause of the gap 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 the third cause of the gap between the generations.In a traditional culture, senior people are valued for their knowledge, but in our society the knowledge of a lifetime may become out of date.The young and the old seem to live in two very different worlds, separated by different skills and abilities.No doubt, the generation gap will continue in American life for some time to come. 1.The first paragraph tells us that ______.
