5.Gallup used to conduct a poll(投票) that asked students to name the school subject that they considered to be the most difficult.Not(51)A,mathematics came out on top of the difficulty chart.So what is it about math that makes it difficult?
Dictionary.com defines the word"difficult"as"not easily or readily done; requiring much(52)B or planning to be performed successfully."This definition gets to the point of the problem when it comes to math.What makes math difficult is that it takes patience and persistence.For many students,math is not something that comes(53)C.It takes effort.It is a subject that sometimes requires students to devote lots and lots of time and(54)D.
This means,for many,the problem has little to do with brain power; it is mostly a matter of staying power.And since students don't make their own timelines,they can (55)B the time as the teacher moves on to the next topic.
In fact,there is also an element of brain style in the big picture,according to many scientists.They believe that people are born with (56)Cmath understanding skills.Logical,left-brain thinkers tend to understand things in sequential bits,while artistic,intuitive,right-brainers are more(57)B.They take in a lot of information at one time and allow time to let it"sink in".so left-brain students may grasp concepts(58)A while right-brain students don't.To the right brain student,time loss can make them feel confused and behind.Unfortunately in busy classrooms with too many students,students are mot always (59)C enough time.We have to move on,ready or not.
Math know-how is also cumulative(积累),which means it works much like a pile of building blocks.You have to gain enough(60)D in one area before you can effectively go on to"build upon"another area.Our first mathematical building blocks are established in primary school,when we learn (61)B for addition and multiplication,and those first concepts become our(62)C.These mathematical concepts or knowledge has to sink in and become(63)C before students can move on to challenge the next stage of new concepts.However,teachers don't have time to ensure that every single student understands every single concept.So some students move to the next level with really shaky knowledge system.(64)D,as they climb the ladder,they may meet with more and more difficulties and might (65)C complete failure at some point.

分析 盖洛普曾进行的一项民意调查结果表明:学生们普遍认为数学是最难的学科.
本文作者主要是根据这一调查结果通过以下几个方面分析了其产生的原因即:为什么学生们认为数学是最难的学科?首先,作者认为学习数学需要有耐心并且有毅力,有时还需要花费大量的时间与精力,而许多学生却做不到的;其次,许多科学家认为,这与大脑的思维模式有关.他们认为人生来就有数学理解能力,左脑思考者通常具有逻辑性,他们倾向于以连贯的思维方式理解问题;右脑思考者倾向于凭直觉并且讲求艺术性,习惯从整体上全面地理解问题,因此这往往需要花费很多的时间,于是便造成了右脑思考者在学习数学上的困惑与落后;最后,作者提到数学的学习也是一个积累的过程,需要打好基础,熟练掌握学过的知识,但是在学生众多而且学习比较紧张的课堂上,老师们不可能保证每一个学生们都能牢固掌握所学知识,这就使得有些学生的知识体系不够完善,也是造成学生们感觉数学难的原因.

解答 答案:51-55  ABCDB  56-60 CBACD     61-65  BCCDC
51.A   副词词义辨析   根据前后句可知,该句表达的意思是:在民意调查中让学生们说出他们认为最难的科目,数学出现在了调查难度表的榜首,这是不足为奇的;故选A
52.B   名词词义辨析   前一句对difficult的定义进行来分析,强调的是做某事不容易;因此需要付出努力才能完成;labor:劳动,努力,工作;故选B
53.C   副词词义辨析   前一句讲了学习数学的难点在于它需要耐心与毅力,因此这里的意思应是:对于很多学生来说,数学并不是自动生成的;regularly:定期地,有规律地;automatically:自动地,无意识地;故选C
54.D   名词词义辨析   根据上文可知,学习数学需要努力,因此有时要付出大量的时间与精力;故选D
55.B   动词短语辨析   根据前一句可知,由于学生没有合理地制定学习时间表,因此当老师转入下一个课题时,他们就没时间复习了;A.make up for 补偿,弥补; B.run out of 用完,耗尽;C.take advantage of利用; D.add up to 总计,累计;故选B
56.C   形容词词义辨析  根据下文科学家对左脑以及右脑思考者习惯的分析可知,他们认为对于数学人们生来就有着不同的理解能力;故选C
57.B   形容词词义辨析  根据上文提到的左脑思考者通常具有逻辑性,他们倾向于以连贯的思维方式理解问题;此处对应的右脑思考者倾向于凭直觉并且讲求艺术,则应是全面地理解问题;global 全面的,整体的;specific 具体的,明确的;故选B
58.A   副词词义辨析   结合上下文可知,由于右脑思考者一次性吸入了大量的信息,因此需要很多的时间来领会,所以掌握概念时会不如左脑思考者快;故选A
59.C   动词短语辨析  根据前后句可知,在学生众多而且学习比较紧张的课堂上,学生们不可能总是很幸运会有太多的时间来巩固复习,无论他们是否已准备好,都将继续往下学;A.reminded about 提醒; B.exposed to 接触到;  C.blessed with 幸运有; D.accused of 指责,被指控;故选C
60.D   名词词义辨析  根据上一句将数学知识的作用比作是一堆积木,可知,此处指的是你必须在一个区域中获得足够多的积木,才能有效地去"建立"另一个领域;故选D
61.B   名词词义辨析   根据前一句可知,此处表达的是小学时学的数学基础知识,即加法与乘法规则;故选B
62.C   名词词义辨析   此处是承接了前一句,指最早学的加法与乘法等概念变成了我们的基础;故选C
63.C   形容词词义辨析  根据上文可知,此处是针对前面的分析下的结论,and之前的sink in 表达的意思应与其后的空白处一致即:这些数学概念或知识必须被领会并且被牢固掌握; B.accessible 易接近的,可理解的;C.firm 牢固的,坚定的;D.superior 较多的,上等的;故选C
64.D   介词短语辨析  由于上文认为分析了学生们认为数学难学的原因,而下文讲到的是爬梯子,因此此处是在举例说明;故选D
65.C   动词词义辨析  根据上文可知,此处是举例说明没有学好数学的原因即:当他们往上爬梯子的时候,他们可能会遇到越来越多的困难,在某个地方可能会遭受彻底的失败;这里指遭受失败;故选C

点评 做本题时,首先应快速通读全文,把握文章的大意;其次要在理解的基础上,结合上下文的语意提示,选出正确的答案;最后完形填空题的选项设置中通常包括名词,动词,形容词,副词等的词义辨析,因此除了需要根据语意进行选择外,还应注意区分词义的不同;所以平时在增加阅读量的同时,还应注意积累词汇量并熟练掌握它们之间的不同用法.
