【正确答案】 C

【答案解析】[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. The nuclear family consists of only one father, one mother, and children; it is becoming the main family structure everywhere. The nuclear family 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 nuclear families, men and women usually make an equal number of decisions about family life. But wives usually have to 'pay' for the benefits of freedom and power. When women lived in extended families, sisters, grand-parents, and aunts helped one another with housework and childcare. In addition, older women in a large family group had important positions. Wives in nuclear families do not often enjoy this benefit, and they have another disadvantage, too: women generally live longer than their husbands, so older women from unclear 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 fulltime jobs, and they have not much free time. Who used to live together in an extended family? 推理题。过去大家庭当中，会有祖父母、父母和子女，有时家族当中还会有几个兄弟和他们的妻子儿女。可见大家庭当中有很多亲戚。其余三个选项都只是其中的一部分。
