问题 One of the fundamental problems with learning mathematics is that while the number sense may be (i)________, exact calculation requires cultural tools—symbols and algorithms —that are relatively new and must therefore be absorbed by areas of the brain designed for other purposes, which is easier when what we are learning (ii)________our built-in circuitry. With an understanding of it, we can at least (iii)________our teaching methods by reflecting on the constraints it imposes.
Blank (i)   Blank (ii)         Blank (iii)
A. innate   D. harmonizes with G. preserve
B. modern   E. intrudes on     H. discard
C. complex  F. goes beyond     I. adapt

选项

答案A,D,I

解析 空格(i)表示的是数字感(number sense)可能是怎么样的,后面在说,精确的计算(exact calculation)需要文化工具________符号和算法________这些东西相对来说是比较新的(that are relatively new),因此必须被用于其他目的的大脑区域所吸收,体现出这是后天习得的事情,这里注意number sense与exact calculation构成了对比,所以前面的number sense应该是一个天生的概念。因此,这里选择A项innate最合适。这道题目在New Yorker官网中找到了题源,原文中空格(i)给出的词汇是genetic。注意空格(ii)前面的which指代的是absorbed by areas of the brain designed for other purpose这件事。前面是一个复杂的过程,那么空格(ii)表示的是当我们学习的知识(what we are learning)怎么样了我们内在的回路的时候,这件事将会更简单(which is easier),所以这里应该对which之前的概念取反。前面说必须后天学习,所以这里就应该体现出内在,因此选择D项harmonizes with。空格(iii)所在句子中,with all understanding of it,这里的it指的是最前面说的one of the fundamental problems。在理解了这个问题之后,我们至少(at least)去怎么样我们的教学方法。空格(iii)应填入一个正评价概念,所以排除掉H选项。by引导的是一种手段方式,后面说去反思它所给予的限制(by reflecting on the constraints it imposes),既然考虑了问题给我们施加的限制,我们显然应该是去适应(adapt)这个问题,而不是沿用以前的方法(preserve),所以空格(iii)选择I项adapt。
