单选题Telecommuting—substituting the computer for the trip to the job—has been hailed as a solution to all kinds of problems related to office work. For workers it promises freedom from the office, less time wasted in traffic, and help with childcare conflicts. For management, telecommuting helps keep high performers on board, minimizes lateness and absenteeism by eliminating commuters (经常乘火车往返者), allows periods of solitude (独处) for high concentration tasks, and provides scheduling flexibility. In some areas, such as Southern California and Seattle, Washington, local governments are encouraging companies to start telecommuting programs in order to reduce rush—hour traffic and improve air quality. But these benefits do not come easily. Marking a telecommuting program work requires careful planning and an understanding of the differences between telecommuting realities and popular images. Many workers are seduced by rosy illusions of life as a telecommuter. A computer programmer from New York City moves to the quiet Adirondack Mountains and stays in contact with her office via computer. A manager comes in to his office three days a week and works at home the other two. An accountant stays home to care for her sick child; she child; she hooks up her telephone modern connections and does office work between calls to the doctor. These are powerful images, but they are a limited reflection of reality. Telecommuting workers soon learn that it is almost impossible to concentrate on work and care for a young child at the same time. Before a certain age, young children cannot recognize, much less respect, the necessary boundaries between work and family. Additional child support is necessary if the parent is to get any work done. Management, too, must separate the myth from the reaity. Although the media has paid a great deal of attention to telecommuting, in most cases it is the employee's situation, not the availability of technology, that precipitates (加速……来临) a telecommuting arrangement. That is partly why, despite the widespread press coverage, the number of companies with work- at- home programs or policy guidelines remains small.

单选题Concerning money or anything else, conflicts between husband and wife usually reflect a power struggle. Conflicts between parent and child often center around the same issue. As children enter adolescence, they begin to demand greater freedom to go where they please, do what they please, and make decisions without parental interference. Many American parents do not know how to deal with their teenagers and seek advice from books, lectures, and parent-training courses. Parents want to maintain a friendly relationship with their teenagers and also want to guide them so that their behavior will be whatever the parents consider proper and constructive. But in a society of rapidly changing social and moral values, parents and children often disagree aboutwhat is important and what is right. Arguments may concern such unimportant matters as styles of dress or hairdos. But quarrels may also concern school work, after school jobs, decisions, use of the family car, dating, and sex behavior. Some families have serious problems with teenagers who drop out of school, run away from home, or use illegal drugs. Because so much publicity is given to the problem teenager, one gets the impression that all teenagers are troublemakers. Actually, relatively few adolescents do anything wrong, and nearly all grow up into "solid citizens" who fulfill most of their parents" expectations. In fact, recent studies show that the "generation gap" is narrowing. The vast majority of teenagers share most of their parents" values and ideas. Many parents feel that they get along with their adolescents quite well.
