【正确答案】 D

【答案解析】[解析] 10-12 I used to think I could quit checking my e-mail any time I wanted to, but I stopped kidding myself years ago. My E-mail program is up and running 24 hours a day, and once I submit to its siren call, whole hours can go missing. I have a friend who recently found herself stuck on a cruise ship near Panama that didn't offer e-mail, so she chartered a helicopter to take her to the nearest Internet cafe. There was nothing in her queue but junk mail and she thought the trip was worth it. I know how she felt. You never know when you're going to get that note from Uncle Eric about your inheritance or that White House dinner invitation with a time-sensitive R. S. V. P. My friend and I are not alone. According to a Gartner Group study, 42% of American e-mail users—and there are more than 100 million of us — check e-mail on vacation. Nearly I in 4 look for messages every weekend. Dr. David Greenfield, founder of the Center for Internet Studies in west Hartford, Conn., believes that at least 6% of us are what he would classify as compulsive e-mail checkers. "It sounds silly, but people report that they feel like they prefer to be alone and not want to talk to others when they're away from e-mail," he says. "It's very likely the brain gets the same kind of hit from e-mail as it does from gambling." 10. Why did the woman's friend feel anxious aboard the ship near Panama?
