Women’s roles have changed throughout the world in recent years, but nowhere so obviously as in America .As the roles of women have changed ,so have men’s .In many American homes today ,the husband still carries on his traditional role of breadwinner ,while his homemaker wife is in charge of the home and child—raising. But it is more and more common to find that the children are left in day –care centers or nursery schools while both parents work .The woman may earn as much or more money than her husband. At home ,household duties are shared in varying degrees by all family members .It is not unusual to find father cooking dinner ,cleaning the living room or changing the baby .Mother might be outside mowing the lawn or washing the car .Children have responsibilities ,too .One of the goals of the Women’s Liberation Movement has been to have both men and women share in childcare, housework and financial responsibility. Today many American women will not marry a man who is not willing to share equally in household responsibilities. The high cost of living has made it necessary for many women to have jobs outside the home ,but women often choose to have jobs in order to use their skills and education or to seek a more fulfilling and interesting life .Many American women enjoy the independence that an outside job and the salary give men and even some women—sometimes are not for women working outside the home ,and in some cases ,a woman might be paid less than a man who performs the same job .American women ,however ,have met challenges（挑战）since pioneer days ,and they continue to work for true equality. 45．Many American women go out to work in order to            .
