问题     Mathematical ability and musical ability may not seem on the surface to be connected, but people who have researched the subject—and studied the brain—say that riley are. Three quarters of the bright but speech-delayed children in the group I studied had a close relative who was an-engineer, mathematician or scientist and four fifths had a close relative who played a musical instrument. The children themselves usually took readily to math and other analytical subjects and to music.
    Black, white and Asian children in this group show the same patterns. However, it is clear that blacks have been greatly overrepresented in the development of American popular music and greatly underrepresented in such fields as mathematics, science and engineering.
    If the abilities required in analytical fields and in music are so closely related, how can there be this great discrepancy? One reason is that the development of mathematical and other such abilities requires years of formal schooling, while certain musical talents can be developed with little or no formal training, as has happened with a number of well-known black musicians.
    It is precisely in those kinds of music where one can acquire great skill without formal training that blacks have excelled popular music rather than classical music, piano rather than violin, blues rather than opera. This is readily understandable, given that most blacks, for most of American history, have not had either the money or the leisure for long years of formal study in music.
    Blacks have not merely held their own in American popular music. They have played a disproportionately large role in the development of jazz, both traditional and modern. A long string of names comes to mind—Louis Armstrong, Charlie Parker... and so on.
    None of this presupposes any special innate (先天的) ability of blacks in music. On the contrary, it is perfectly consisted with blacks having no more such inborn ability than anyone else, but being limited to being able to express such ability in narrower channels than others who have had the money, the time and the formal education to spread out over a wider ranger of music, as well as into mathematics, science and engineering.
The passage mainly answers which of the following questions?
选项 A、Are musical ability and mathematical ability connected?
B、Why have blacks been greatly over represented in the development of American popular music?
C、What kinds of music require formal training?
D、What are the contributions made by black musicians?
答案B
解析 主旨大意题。根据文章的首段和末段可知文章的主题。文章开头虽然是关于A“音乐能力和数学能力是有联系的吗”的论述，但文章结尾下结论处却远远离开了音乐和数学的关系，可见A只是文章的出发点；选C“什么种类的音乐需要正规训练”和D“黑人音乐家都做出了哪些贡献”的同学舍本求末，将论述中牵涉到的一些细节问题当成了中心论点。因此选项B“为什么黑人在美国流行音乐的发展中具有如此大的代表性”不仅是基于全篇的归纳，而且是篇尾直接回答的问题。
