填空题 Demographic indicators show that Americans in the postwar period were more eager than ever to establish families. They quickly brought down the age at marriagefor both men and women and brought the birth rate to a twentieth century height 1after more than a hundred years of a steady decline, producing the"baby boom. " 2These young adults established a trend of early marriage and relatively largefamilies that went for more than two decades and caused a major but temporary 3reversal of longterm demographic patterns. From the 1940s through the early1960s, Americans married at a high rate and at a younger age than their 4Europen counterparts. 5 Less noted but equally more significant, the men and women who formed 6families between 1940 and 1960 nevertheless reduced the divorce rate after a 7postwar peak: their marriages remained intact to a greater extent than did that of 8couples who married in earlier as well as later decades. Since the United States 9maintained its dubious distinction of having the highest divorce rate in the world,the temporary decline in divorce did not occur in the same extent in Europe. 10Contrary to fears of the experts, the role of breadwinner and homemaker was not abandoned.
