问题     People appear to be born to compute. The numerical skills of children develop so early that it is easy to imagine an internal clock of mathematical maturity guiding their growth. Not long after learning to walk and talk, they can set the table with impressive accuracy--one plate, one knife, one spoon, one fork. Soon they are capable of noting that they have placed five knives, spoons, and forks on the table and, a bit later, that this amounts to fifteen pieces of silverware. Having thus mastered addition, they move on to subtraction, It seems almost reasonable to expect that if a child were secluded (使...隐居) on a desert island at birth and returned seven years later, he or she could enter a second-grade mathematics class without any serious problems of intellectual adjustment.
    Of course, the truth is not so simple. This century, the work of cognitive(认知的) psychologists had illuminated the subtle forms o? daily learning on which intellectual progress depends. Children were observed as they slowly grasped concepts that adults take for granted, as they refused, for instance, to concede that quantity is unchanged as water pours from a short stout glass into a tall thin one.  Psychologists have demonstrated that young children, asked to count the pencils in a pile, readily report the number of blue or red pencils, but must be coaxed (哄) into finding the total. Such studies have suggested that the basics of mathematics are mastered gradually, and with effort. They have also suggested that the very concept of abstract numbers is itself far from innate. [br] The word "illuminated" in line 10 is closest in meaning to ______.

选项 A、illustrated
B、accepted
C、clarified
D、lighted

答案 C

解析 语义题。文中“illuminate”是阐明的意思,与clarify(阐明、解释、澄清)的意思一致。即,心理学者阐明:一些日常生活中的学习是人的知识累计的基础。而A选项illustrate意指举例说明,与illuminate的意思不同。特别提示:本题难度较大,不仅要考考生对文章的理解,而且要求考生在平时学习中,要准确把握词汇的含义,注意意思相近的词汇的比较。
