  • 第22题:

    单选题
    The first paragraph implies that ______.
    A

    there is a conflict between laws and public opinions on the purpose of education.

    B

    the moral purpose of education varies in form with the social situation.

    C

    Greeks and the medieval Church had the same moral purpose in education.

    D

    the moral purpose of education is to advocate religious beliefs.


    正确答案: B
    解析:
    推理判断题。根据题干信息定位到第一段第三句“In today’s world,the moral purpose of education takes non—religious forms:racial integration,sex education,good citizenship”,由此可知,在当今世界,道德教育采取非宗教形式:种族融合、性教育以及公民教育,从而可以判断出在不同时代社会状况下,道德教育的形式也不一样,故B选项正确;同时 D项意为教育的道德目的是为了拥护宗教信仰,陈述过于片面和绝对,故排除;第一段第一句只是提及美国最高法院禁止公立学校举行祈祷仪式,并不代表法律和公众在教育目的的观点上存在矛盾,曲解文意,故A项错误;第一段第二句提到“It is an idea common to both the Greeks and the medieval Church”,即希腊和中世纪的教会都认同道德教育应该是教育的目的之一,并不能转述为两者道德教育的目的一致,故C项错误。
