问题     The idea that music makes you smarter has received considerable attention from scholars and the media. Current interest in【B1】______between music and intelligence stems from two independent areas of research. One focuses on short-term effects of【B2】______listening to music. The other is on a seperate【B3】______of research, which examines whether music lessons have【B4】______benefits that extend to non-musical areas of cognition. Such 【B5】______ could be unique to children who take music lessons for long periods of time 【B6】______ their experiences differ substantially from those of other children. Music lessons【B7】______long periods of focused attention, memorization of【B8】______musical passages, learning about a variety of musical structures, and【B9】______mastery of technical skills and the conventions【B10】______the expression of emotions in performance. This【B11】______of experiences could have a positive impact on cognition, particularly during the childhood years, when brain devolopment is highly【B12】______and sensitive to environmental influence.
    Previous findings are【B13】______with the hypothesis that music lessons promote intellectual development. For example, natural musical gifts is associated with literacy.【B14】______, correlational and experimental studies【B15】______that music lessons have positive relations with verbal memory, reading ability, selective attention, and mathematics achievement.【B16】______, the simplest explanation of these【B17】______relations is that they come from a common component,such as general intelligence. Put simply, children【B18】______high IQs are more likely than other children to take music lessons. To conclude that music lessons have a casual relation with IQ that is【B19】______to music,one must rule【B20】______potentially confusing factors such as socioeconomic status, and education, and demonstrate that non-musical, extracurricular activities do not have comparable effects on IQ.
【B12】

选项 A、plastic
B、dependent
C、complex
D、touchy

答案A

解析 考查上下文语义。空格处所在句意为:儿童时期的大脑发展非常______而且对环境影响很敏感。此处是用来解释“这些经历对孩童时期的认知有积极的影响”。A.plastic可以表示“可塑的”,代入文中,表示“儿童的大脑发展具有可塑性”,符合文意。dependent“依赖的”:complex“复杂的”;touchy“过于敏感的,棘手的”,均不符合文意。
