单选题Promptness is important in American business, academic, and social settings. The importance of punctuality is taught to young children in school. Tardy slips and the use of bells signal to the child that punctuality and time itself are to be respected. People who keep appointments are considered dependable. If people are late to job interviews, appointments, or classes, they are often viewed as unreliable and irresponsible. In the business world, "time is money" and companies may fine their executives for tardiness to business meetings. Of course, it is not always possible to be punctual. Social and business etiquette also provides rules for late arrivals. Calling on the telephone if one is going to be more than a few minutes late for scheduled appointments is considered polite and is often expected. Keeping a date of a friend waiting beyond ten to twenty minutes is considered rude. On the other hand, arriving thirty minutes late to some parties is acceptable.

单选题Contrary to the impression that grandmothers are delighted to help their grown daughters and care for their grandchildren, a study of multigenerational families indicates that many older women resent the frequent impositions of the younger generations on their home and energy. "Young women with children are under a lot of pressure these days, and they expect their mothers to help them pick up the pieces," noted Dr. Bertram J. Cohler, a behavioral scientist at the University of Chicago. "This is often the strongest source of resentment on the part of Grandmother, who has finished with child caring and now has her own life to live. Grandmothers like to see their children and grandchildren, but on their own time." In all the four New England families studied, the older women resented the numerous phone calls and visits from their grown daughter, who often turned to their mothers for advice, physical resources, affection, and companionship as well as baby sitting services. "American society keeps piling on the burdens for older people, particularly those in their 50s and 60s," Dr. Cohler said in an interview here. "They're still working and they're taking care of their grown children and maybe also their aged parents. Sometimes life gets to be too much. That's one reason many older folks move far away, to Florida or Arizona. They need more space and time to attend to their own affair and friends. Young people don't understand this, and that's part of what create tension between generations." He has found that, contrary to what the younger generations may have thought, older people have an enormous amount to do. "More than half of working-class grandmothers still work, and if they' re retired they have activities in the community that keep them occupied," he said. "Each generation has got to appreciate the unique needs of the other," Dr. Cohler went on. "The younger generation has to realize that grandparents have busy, active lives and that they need privacy and more space for themselves. And the older generation has to realize that continuing to be part of the family is important to the younger generation and that they need help and support." He noted that problems with interdependence between generations were likely to be more intense in working-class families than in middle and upper-class families. He explained that the working class tended to be geographically less mobile and to have fewer outside resources and that daughters were more likely to be reared with a strong family orientation and less emphasis on establishing an independent life.
