单选题Before high school teacher Kimberly Rugh got down to business at the start of a recent school week, she joked with her students about how she'd had to clean cake out of the corners of her house after her 2-year-old son's birthday party. This friendly combination of chitchat took place not in front of a blackboard but in an E-mail message that Rugh sent to the 145 students she's teaching at the Florida Virtual School, one of the nation's leading online high schools. The school's motto is "any time, any place, any path, any pace". Florida's E-school attracts many students who need flexible scheduling, from young tennis stars and young musicians to brothers Tobias and Tyler Heeb, who take turns working on the computer while helping out with their family's clam-farming business on Pine Island, off Florida's southwest coast. Home-schoolers also are well represented. Most students live in Florida, but 55 hail from West Virginia, where a severe teacher shortage makes it hard for many students to take advanced classes. Seven kids from Texas and four from Shanghai round out the student body. The great majority of Florida Virtual Schooler-- 80 percent are enrolled in regular Florida public or private high schools. Some are busy overachievers. Others are retaking classes they barely passed the first time, The school's biggest challenge is making sure that students aren't left to sink or swim on their own. After the school experienced a disappointing course completion rate of just 50 percent in its early years, Executive Director Julie Young made a priority out of what she calls "relationship-building," asking teachers to stay in frequent E-mail and phone contact with their students. That personal touch has helped: The completion rate is now 80 percent. Critics of online classes say that while they may have a limited place, they are a poor substitute for the face-to-face contact and socialization that take place in brick-and-mortar classrooms. Despite opportunities for online chats, some virtual students say they'd prefer to have more interaction with their peers. Students and parents are quick to acknowledge that virtual schooling isn't for everyone. "If your child's not focused and motivated, I can only imagine it would be a nightmare," says Patricia Haygood of Orlando, whose two daughters are thriving at the Florida school. For those who have what it takes, however, virtual learning fills an important niche. "I can work at my own pace, on my own time," says Hackney. "It's the ultimate in Student responsibility./

单选题Researchers have studied the poor as individuals, as families and households, as members of poor communities, neighborhoods and regions, as products of larger poverty-creating structures. They have been analyzed as victims of crime and criminals, as members of minority cultures, as passive consumers of mass culture and active producers of a "counterculture", as an economic burden and as a reserve army of labor——to mention just some of the preoccupations of poverty research. The elites, who occupy the small upper stratum within the category of the non-poor, and their functions in the emergence and reproduction of poverty are as interesting and important an object for poverty research as the poor themselves. The elites have images of the poor and of' poverty which shape their decisions and actions. So far, little is known about those images, except as they are sketchily portrayed in popular stereotypes. The elites may well ignore or deny the external effects of their own actions(and omissions) upon the living conditions of the poor. Many social scientists may take a very different view. As poverty emerged and was reproduced, legal frameworks were created to contain the problems it caused with profound, and largely unknown, consequences for the poor themselves. In general, political, educational and social institutions tend to ignore or even damage the interests of the poor. In constructing a physical infrastructure for transport, industry, trade and tourism, the settlements of the poor are often the first to suffer or to be left standing and exposed to pollution, noise and crowding. Most important are the economic functions of poverty, as for lack of other options the poor are forced to perform activities considered degrading or unclean. The poor are more likely to buy second-hand goods and leftover foodstuffs, thus prolonging their economic utility. They are likely to use the services of low-quality doctors, teachers and lawyers whom the non-poor shy away from. Poverty and the poor serve an important symbolic function, in reminding citizens of the lot that may befall those who do not heed the values of thrift, diligence and cleanliness, and of the constant threat that the rough, the immoral and the violent represent for the rest of society. Physically, the poor and the non-poor are kept apart, through differential land use and ghettoization. Socially, they are separated through differential participation in the labor market, the consumption economy, and in political, social and cultural institutions. Conceptually, they are divided through stereo- typing and media cliche. This separation is even more pronounced between the elites and the poor.
