Task 2 Directions: This task is the same as Task 1. The 5 questions or unfinished statements are numbered 41 through 45. A few years ago it was common to speak of a generation gap between young people and their elders. Parents said that children did not respect and listen to them, while children said that their parents did not understand them at all. What had gone wrong? Why had the generation gap suddenly appeared? Actually, the generation gap has been around for a long time. Many people argue that it is built into every part of our society. 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 axe expected to live in the same place 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culture, senior people axe valued for their knowledge, but in our society the knowledge of a lifetime may become out of date.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. The first paragraph tells that ______.
A.
the problem of the generation gap draws much attention from people
B.
it is out of date to talk about the generation gap
C.
children and parents are trying to understand each other
D.
it is very important for people to talk with each other often
