[单项选择]More American mothers than ever are working, and more workers are mothers. Yet their march into the world of paid work continues to cause suspicion. One recent survey found that 48 percent of Americans believe that preschoolers suffer if their mothers work, while another found that 42 percent of employed parents think that working mothers care more about succeeding at work than meeting their children’s needs.
All mothers deserve our support--those who care for children at home and those who have joined the work force. But many working mothers continue to believe that they are shortchanging (少找钱)their children. They shouldn’t. Research tells us that kids do just fine when mothers work.
Suzanne Bianchi a scientist of the University of Maryland, has found that mothers today spend as much if not more time with their children than they did in 1965, even though the percentage of mothers who work rose from 35 percent to 71 percent. Then there are the obvious financial benefits. For
A. society should support all mothers no matter where they work—at home or outside it
B. working mothers are doing less for their children
C. we should do more research on this problem
D. working mothers should be proud
