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 Schoolers—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." Kimberly Rugh Talked about her son's birthday party ______ . A．with her friends B．with her colleagues C．in the classroom D．in an E-mail massage sent to her students

Why is it that so many mothers like mine think of themselves as second-class or something similar？ Where has this notion come from？ Have we males made them feel this way？ Has our society made "going to work" outside the home seem more important than what a house wife must face each day？ I would be very curious to see what would happen if a housewife went on strike. Dishes would pile up. Food in the house would run out. No meals would appear on the table. There would be no clean clothes when needed. High boots would be required just to make it through the house scattered with garbage. Walking and bus riding would increase. Those scout troops would have to break up. Charities would suffer. I doubt if the man of the house would be able to take over. Oh, he might start out with the attitude that he can do just as good a job, but how long would that last？ Not long, once he had to come home each night after work to more household duties. There would be no more coming home to a prepared meal; he'd have to fix it himself. The kids would all be screaming for something to eat, clean clothes and more bus fare money. Once he quieted the kids, he'd have to clean the house, go shopping, make sure that kids got a bath, and fix lunches for the next day. Once the kids were down for the night, he might be able to crawl into an unmade bed and, try to read the morning newspaper. No, I don't think many males are going to volunteer for the job. I know I don't want it. So, thanks, mom! I'll do what I can to create a national holiday for housewives. It could be appropriately called Wonder Woman Day. By what means do the children of the author's family go to school？ A．They take school bus. B．They take a taxi. C．Their mother drives for them. D．Scout troop sends them to school.
