The greatest recent changes have been in the lives of women. During the twentieth century there was an unusual shortening of the time of a woman’s life spent in caring for children. A woman who got married at the end of the 19th century would probably have been in her middle twenties, and would be likely to have seven or eight children, of whom four or five lived till they were five years old. By the time the youngest was fifteen, the mother would have been in her early fifties and would expect to live a further twenty years, during which custom, chance and health made it unusual for her to get paid work. Today women get married at a younger age and have fewer children. Usually a woman’s youngest child will be fifteen when she is forty-five and is likely to take paid work until retirement at sixty. Even while she has the care of children，her work is lightened by household appliances （家用电器）and convenience foods.

　　This important change in women’s way of life has only recently begun to have its full effect on women’s economic position. Even a few years ago most girls left school at the first opportunity and most of them took a full-time job. However, when they got married, they usually left work at once and never returned to it. Today the school-leaving age is sixteen, Many girls stay at school after that age, and though women tend to get married young, more married women stay at work at least until shortly before their first child is born. Many more return afterwards to a full-time or part-time job. Such changes have led to a new relationship in marriage, with both husband and wife accepting a greater share of the duties and satisfaction of family life, and with both husband and wife sharing more equally in providing the money and running the home, according to the abilities and interest of each of them.
