One of the most important social developments that helped to make possible a shift in thinking about the role of public education was the effect of the baby boom of the 1950s and 1960s on the schools. In the 1920s， but especially in the Depression conditions of the 1930s， the United States experienced a declining birth rate—every thousand women aged fifteen to forty-four gave birth to about 118 live children in 1920， 89.2 in 1930， 75.8 in 1936， and 80 in 1940. With the growing prosperity brought on by the Second World War and the economic boom that followed it， young people married and established households earlier and began to raise larger families than had their predecessors during the Depression. Birth rates rose to 102 per thousand in 1946， 106.2 in 1950， and 118 in 1955. Although economics was probably the most important determinant， it is not the only explanation for the baby boom. The increased value placed on the idea of the family also helps to explain this rise in birth rates.The baby boomers began streaming into the first grade by the mid-1940s and became a flood by 1950. The public school system suddenly found itself overtaxed. While the number of schoolchildren rose because of wartime and postwar conditions， these same conditions made the schools even less prepared to cope with the flood. The wartime economy meant that few new schools were built between 1940 and 1945. Moreover， during the war and in the boom times that followed， large numbers of teachers left their profession for better-paying jobs elsewhere in the economy.

Therefore， in the 1950s and 1960s， the baby boom hit an antiquated and inadequate school system. Consequently， the “custodial rhetoric” of the 1930s and early 1940s no longer made sense; that is， keeping youths aged sixteen and older out of the labor market by keeping them in school could no longer be a high priority for an institution unable to find space and staff to teach younger children aged five to sixteen. With the baby boom， the focus of educators and of laymen interested in education inevitably turned toward the lower grades and back to basic academic skills and discipline. The system no longer had much interest in offering nontraditional， new， and extra services to older youths.

4.B 推断题。作者在第三段首句提到生育高峰冲击了学校体系，可排除A;最后一段提到教育者的焦点也转向了低年级，转回到了基本的学术技能和学科上，而对向年龄较大的年轻人提供非传统的、新式的和额外的服务不再抱有太多的兴趣，言外之意，在生育高峰之前教育者的焦点不在基本的学术技能和学科上，故排除c，D与文意正好相反，只有B符合文意。

5.C 主旨题。本题针对文章的大意。文章开篇作者就点明了主题“促使人们在对公共教育的作用的思考上发生转变的最重要的社会状况之一，就是20世纪50年代和60年代生育高峰对学校的影响”。由此可见，本文的主旨应为C.
