问题     People appear to be born to compute. The numerical skills of children develop so early and so inexorably 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,for each of the five chairs. 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 on a desert island at birth and retrieved 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 psychologists has illuminated the subtle forms of daily learning on which intellectual progress depends. Children were observed as they slowly grasped-or.as the case might be bumped into-the 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 since 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 into finding the total. Such studies have suggested that the rudiments of mathematics are mastered gradually,and with effort. They have also suggested that the very concept of abstract numbers-the idea of a oneness,a twoness.a threeness that applies to any class of objects and is a prerequisite for doing anything more mathematically demand ing than setting a table-is itself far from innate.
With which of the following would the author be LEAST likely to agree?
选项 A、Children naturally and easily learn mathematics.
B、Children learn to add before they learn to subtract.
C、Most people follow the same pattern of mathematical development.
D、Mathematical development is subtle and gradual.
答案A
解析 题目问：作者最不可能同意下列哪项?第二段首句，“Of course，the truth is not so simple．”该段第五句“Such studies have suggested that the rudiments of mathematics are mastered gradually，and witheffort．”通过这段话可知，虽然孩子很早就具备了简单运算能力，但是，这种能力并非是天生的，它需要后天的努力，才能真正掌握。据此判断，应选择A。
