单选题 Is the American family in trouble? Today, about one out of three marriages end in divorce (离婚), and more and more of them involve children. The divorce rate in America is still the highest in the world, but 75% of the women and 85% of the men who divorce remarry with in three years. About 18 million children are living with their step brothers and sisters.
One of the biggest problems facing families today is the rising cost of raising a child. Experts say that at today's prices, a family of four, earning $ 20 000 a year, should expect to spend over $ 55 000 to sup port a child to the age of 18 and this does not include the money for college education. Many women are supporting the family by going back to work. Today, one-half of all married women with school-age children have some kinds of job outside the home. Most mothers work because they need money. As a result, an American child usually spend most weekends with day-care workers or teachers and other children and not with his or her family. Economic conditions kept the early families of America together, and now in modern society, economic conditions are the reason for their moving apart.
