Most women in Ghana--the educated and illiterate (文盲), the urban and rural, the young and old--work to earn an income in addition to(此外，除了)maintaining their roles as housewives and mothers.
Nine out of ten women fifteen years of age and over are married. Women say they would like to have six or more children, and in fact an average of seven children is born to every woman. In short, the normal life pattern for most Ghanaian women is to combine (结合)an active role in the economy(经济)with an active role as wife and mother of a large family.
How do these working mothers cope with their different roles in the home and on the job？ Some new ideas are being tried. One of these of family planning to help reduce family size. Another helpful measure is the day-care center, but usually the fees are too high for the poor. Ghanaians realize that more day-care centers are needed. Ghana today is looking for new ways to meet the needs of women and their families, so women can continue to play their roles both in the home and in the economy.
