听力原文： The family is changing. In the past, grandparents, parents, and children used to

live together, and they had an extended family. Sometimes two or more brothers with their wives and children were part of this large family group. But family structure is changing throughout the world. Nowadays, many families consist of only one father, one mother, and children. It is becoming the main family structure everywhere.

The new family structure offers married women some advantages: they have freedom from their relatives, and the husband does not have all the power of the family. Studies show that in these families, men and women usually make an equal number of decisions about family lives.

In the past, wives usually have to pay for the benefits of freedom and power. When women lived in extended families, sisters and grandparents and aunts helped one another with housework and childcare. In addition, older women in a large family group had important positions.

But now, wives do not often enjoy this benefit, and they have another disadvantage too: women generally live longer than their husbands, so older women from these families often have to live alone. Studies show that women are generally less satisfied with marriage than men are. In the past, men worked outside the home and women worked inside. Housework and childcare were a full time job, and there was no time for anything else. Now women work outside and have more freedom than they did in the past, but they still have to do most of the housework. The women actually have two full-time jobs, and they have not much free time.
