单选题In the traditional (传统的) marriage, the man worked at a job to earn money for the family. Most men worked in an office, a factory, or some other places away from the home. Since the man earned the money, he paid the bills (账). The money was used for food, clothes, the house, and other family needs. The man made most of the decisions. He was the boss. In the traditional marriage, the woman seldom worked away from the house. She stayed at home to care for the children and her husband. She cooked meals, cleaned the house, washed the clothes, and did other housework. Her job at home was very important. In recent years, many couples (夫妇) continue to have a traditional relationship of the kind. The man has a job and earns the money for the family. The woman stays at home and cares for the children and the house. Many Americans are happy with the kind of marriage. But some other Americans have a different impression of marriage and family responsibilities (责任). There are two important differences in male (男性) and female (女性) roles (角色) now. One is that both men and women have many more choices. They may choose to marry or to stay single. They may choose to work or stay at home. Both men and women may choose roles that are comfortable for them. A second difference in male and female roles is that within marriage many decisions and responsibilities are shared. The husband and wife may choose to have children, or they may not. If they have children, the man take care of them some of the time, all of the time or not at all. The woman may want to stay at home and take care of the children. Or she may want to go to work. Men and women now decide these things together in a marriage. Many married people now share these decisions and the responsibilities of their families.
