     The round-the-clock( 24小时不断的 ) availability  that cell

phone have brought to people's lives may be taking a toll on

family life, a new study suggests. The study, which followed

more than 1,300 adults over 2 years, found that those who

consistently used a mobile phone throughout the study period

were more likely to report negative "spillover" between work

and home life-and,in turn, less satisfaction with their family

life.

      Spillover essentially(本质上) means that the line between

work and home begins to become unclear. Work life may invade

home life when a parent is taking job-related calls at home,for

instance-or family issues may start to take up work time. For

example,a child may call mom at work,telling her "microwave

exploded" explained Noelle Chesley,an assistant professor of

sociology at the University of Wisconsin-Milwaukee and the

author of the study. The problem with cell phones seems to be

that they are allowing for ever more spillover between work

and home.

     This may be especially true for working women,the study

found. Among men,consistent use of mobile phones seemed to

allow more work issues to creep (潜入)into family time. But

for women,the spillover tended to go in both directions being

"connected" meant that work cut into home time,and family

issues came into work life.

     Cell phones seem to be opening more lines for stressful

exchanges among family members. But there may be ways to

control the spillover, according to Chesley. Employers, she

said,could look at their policies on contacting employees after

hours to make sure their expectations are "reasonable". For

their part,employees could decide that cell phones go off during

family time, Chesley said.
