people appear to born to compute. The numerical skills of children develop so early and so inexorably(坚定地) that i
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---- concepts that adults take for quantity is unchanged as water pours from a short 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(说服) into finding the total. Such studies have suggested that the rudiments(基本原理) 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 twoness that applies to any class of objects and is aprerequisite(先决条件) for doing anything more mathematically demanding than setting a table----is itself far from innate.
Choose correct answers to the question:
1.After children have helped to set the table with impressive accuracy, they ______.
A.are able to help parents serve dishes
B.tend to do more complicated housework
C.are able to figure out the total pieces
D.can enter a second-grade mathematics class
2.It is _____to believe that the quality of water keeps unchanged when it is contained in two different glasses.
A.easy to persuade children
B.hard for most children
C.the innate of most children
D.difficult for both adults and children
3.It can be inferred from the passage that children are likely to _____when they are asked to count all the balls of different colors
A.give the accurate answer
B.count the balls of each color
C.be too confused to do anything
D.make minor mistakes
4.According to this passage,_____is mastered by birth.
A.the ability to survive in a desert island
B.the way of setting tables
C.the basic principles of mathematics
D.the concept of oneness
5.What’s the author‘s attitude towards “children’s numerical skills”?
1.[C] 第1段第3句说的是题干内容，由第4句Soon…句中的five knives...等数字可知孩子会数数了,故可直接选出C。
2.[B] 第2段第3句中they refused... to concede...中的they指children,对比题干与原文意思可知孩子们是“难以相信(理解)，故选B。
4.[B] 这道题目需要认真理解了文章的意思才能正确作答。第1段的主题是:有些数字概念是人天生就有的;第2段的主题是:有一些是后天学习获得的。B是第1段中明确给出的例子，因此这个例子应该支持该段的主题。A 错误地理解了第1段最后举的例子。C和D在第2段最后提到,都不是先天获取的数学知识。
5.[D] 考査全文的观点态度。纵观全文可知，作者很客观、如实地说明事实，分两段报告了心理学家的研究结果，并未做出任何评价，故D正确。题目中的children’s numerical skills即全文的主题。
