Weekend getaways and romantic dinners used to be sweet escapes from the daily working life. Nowadays, vacations are often interrupted by the ding of an instant message on a wireless laptop. That’s not news to modern workers, many of whom may just be getting back from a long winter break during which they worked more than in years past. One-fifth of Americans carry a laptop on vacation. Countless more carry cell phones, many of which can be used to check company e-mail. And why not? With wireless coverage extending, staying connected is . Recently, JetBlue Airways announced a trial of free e-mail and instant messaging services for passengers on one of its aircraft. Other airlines are expected to follow suit. But there’s a hidden cost to companies: employee burnout. Using work cell phones and checking company e-mail at the poolside is not a vacation. “If I were a manager, I would insist that my employees leave their cell phones at work during their vacation and not check their e-mail while away ,” said Dov Eden, an organizational psychologist. “In the long run, the employee will be better rested and better able to perform his or her job.” A nine-year study of more than 12,000 middle-aged men at high risk of heart disease showed that participants who vacationed more had a lower risk of dying than the vacation-deprived(剥夺的). In a nationwide survey, nearly half of the 2,000 s questioned said stress has increased in the past five years, with 75 percent ranking money and work as the leading causes of stress. One way to beat work stress could be to work from home or another remote location. This alternative work arrangement is a win-win set-up. Telecommuting（远程办公）has an overall beneficial effect, because the arrangement provides employees with more control over how they do their work. Telecommuters reported more job satisfaction, less stress and improved work-family balance. 71. According to the first paragraph, Americans carry a cell phone or a laptop on vacation mainly to .
