单选题 Right now, many parents are readjusting to life with their college students at home for a few weeks or months. Most, of course, are delighted to see the kids. And the kids, often exhausted after final exams, are ready for some parental loving care. "The reality is that there is a lot of mixed feelings on both sides, "says Madge Lawrence Treeger, a psychotherapist (精神治疗医师) and former college counselor, the coauthor of Letting Go; A Parents' Guide to Understanding the College Years. Parents who cry when teens leave for college often cheer up pretty quickly in cleaner, quieter, less busy homes — and then welcome the blast of energy that comes in the door with returning students, Treeger says. "But the first time they get in their car and expect to hear NPR (美国国家共用广播电台)and instead get a blast of heavy metal, or the first time they find wet towels on the bathroom floor, reality starts to set in, "she says. Part of that reality: It's not just parents and households that change while students are away. Students change, too. They grow up or at least make some progress in that direction. "You need to negotiate new rules that make sense between adults — but that respect the fact that parents remain in charge of their homes", says Linda Perlman Gordon, a clinical social worker and author of several parenting books. So, while a curfew(父母规定孩子必须在家的时间)may be unreasonable, a plan for kids to text you when they are out late is not, Gordon says. Likewise, expecting kids to join you for dinner every night might be a recipe for disappointment — but asking them to let you know when they have other plans is a matter of simple courtesy. "It's always a challenge to balance the shifting expectations of parents and students", says Marjorie Savage, director of the parent program at the University of Minnesota. Savage likes the advice she heard from one counselor. Treat your returning child like a foreign exchange student—someone who might be persuaded to share your odd customs, while passing on a few of her own. And when and if the going gets rough? Keep in mind that summer is brief — and most upperclassmen don't stay home for a full season, thanks to the lure of internships, travel and summer study. Best of all, the freshman rolling her eyes at your household rules may well evolve into someone like Christina Pfaff. The recent graduate of the University of Richmond in Virginia, is at home with her family for just a few weeks before heading to the East Coast for a waitressing gig and serious job-hunting. But for now, she says, "I've really come to appreciate hanging out with my parents. And I like having family dinners."

单选题Opinion polls are now beginning to show a reluctant consensus that, whoever is to blame and whatever happens from now on, high unemployment is probably here to stay. This means we shall have to find ways of sharing the available employment more widely. But we need to go further. We must ask some fundamental questions about the future of work. Should we continue to treat employment as the norm? Should we not rather encourage many other ways for self-respecting people to work? Should we not create conditions in which many of us can work for ourselves, rather than for an employer'? Should we not aim to revive the household and the neighborhood, as well as the factory and the office, as centers of production and work? The industrial age has been the only period of human history in which most people's work has taken the form of jobs. The industrial age may now be coming to an end, and some of the changes in work patterns which it brought may have to be reversed. This seems a daunting thought. But, in fact, it could offer the prospect of a better future for work. Universal employment, as its history shows, has not meant economic freedom. Employment became widespread when the enclosures of the 17th and 18th centuries made many people dependent on paid work by depriving them of the use of the land, and thus of the means to provide a living for themselves. Then the factory system destroyed the cottage industries and removed work from people's homes. Later, as transport improved, first by rail and then by road, people commuted longer distances to their places of employment until, eventually, many people's work lost all connection with their home lives and the places in which they lived. Meanwhile, employment put women at a disadvantage. In pre-industrial times, men and women had shared the productive work of the household and village community. Now it became customary for the husband to go out to paid employment, leaving the unpaid work of the home and the family to his wife. Tax and benefit regulations still assume this norm today, and restrict more flexible sharing of work roles between the sexes. It was not only women whose work status suffered. As employment became the dominant form of work, young people and old people were excluded-a problem now, as more teenagers become frustrated at school and more retired people want to live active lives. All this may now have to change. The time has certainly come to switch some effort and resources away from the utopian goal of creating jobs for all, to the urgent practical task of helping many people to manage without fulltime jobs.
