GRE数学难题解决办法

 

  新GRE数学对我们来说比较简单,但是也不要忽略其中存在的一些难题,有可能让我们失去很多的分数。下面,出国留学网小编就为大家介绍一下GRE数学难题及解决办法,希望对大家有用。

  一、新GRE数学介绍

  新GRE数学对于学生的认知和理解能力考察较多,数学部分主要关注代数、几何、统计概率等数学概念,同时引入了更多的生活场景并且更加突出对考生解读数字能力的考察。具体题型主要有多选1;多选多;填答案;比大小。

  所以,新GRE考试中的数学考试难度越来越大,难倒了不少考生。虽然GRE数学考试难度加大,但实际上数学题要做对一道比起语文的任何一种题型的正确概率都要大,所以我们要弄清楚新GRE数学的难度,然后对症下药,取得高分。

  二、新GRE数学三大难题及解决办法

  1.数学专业单词不认识

  关于这个问题,基本上没有太好的对策,需要考生多下些功夫,把所有的生词总结出来,一并记忆。

  如果说没有办法或者没有时间把所有的单词都从题目里面挖出来,那么有一个比较好的方法来认识数学生词,就是通过中文来找出英文相对应的翻译。

  2. 虽然单词认识但是题目读不懂

  情况一:

  很多考生也会遇到这样的情况,单词认识,但是题目不明白。这个问题就归结于阅读问题,而这个阅读的问题不仅仅在于单词,而且还在于理解一些数学里面很“口语”化的内容的英文表达。

  这种问题的解决办法就是:在题目里面遇到了这样的说法,自己翻译出来,然后再用同样的语言来造句和自己出题给自己做。

  情况二:

  除了数学中一些口语化的表达,还有一种情况也可以归为单词认识但是不会做的情况,这个情况可以认识是题目生造定义,必须慢慢熟悉他们的说法。

  针对这种情况,考生千万要坚信自己能做对,题目一定没有想象中的难,只不过是颠倒了,或者绕了一下而已。

  3. 做题时间不够

  解决时间不够的问题的最重要的方法在于熟悉数学知识点和常考的考点。

  熟悉知识点分成两个部分,首先第一个是熟悉公式,比如几何里面的图形面积公式,比如方程中根与系数关系公式,因式分解公式等等。熟悉的意义在于当考生在读题的时候就能把题干的语言在脑海中化成公式,从而加快解题速度。考生可以通过多做题达到这一目标。

  另外一种情况是记得具体的数值,比如圆周率的数值3.14,就很重要,在很多圆的计算题中,圆的周长,面积的数值基本上都是314的倍数,比如 628,比如157,等等。还有特殊的直角三角形的边角关系,3、4、5; 5、12、13等等,最好熟记之,以利于减少计算时间。

  三、新GRE数学其他难题

  除了上面给大家介绍的GRE数学中存在的难题,新GRE数学还有其他的难题,那就是图表题的出现。

  图表题我们平时接触的不多,要详细地重点地做。不过图表题里面也有难度的不同,我们最熟悉的柱状和饼状图其实并不难(不难的原因也是我们熟悉),而另外一个相对陌生的题型,比如地形图,频率分布图和table图,尤其是多图联合,要重点地多做练习。

  以上就是小编为大家介绍的GRE数学难...

GRE数学难题破解技巧

  小编为何要介绍GRE数学考试难点成功突破技巧?两大类GRE数学难题举例解析,主要包括以下三种无选项计算题、多项选择题以及判断题。考生们可以针对在新GRE数学中着名的难题,进行专项的锻炼复习,进行GRE数学难题破解,希望考生们取得GRE数学满分。

  无选项计算题

  例:The average(arithmetic mean)of the 11 numbers in a list is 14. If the average of 9 of the numbers in the list is 9,what is the average of the other 2 numbers­(11个数的算术平均数是14。若其中9个数的算术平均数为9,则剩下的2个数的平均数是多少?

  GRE数学样题新题本题考察的是考生对算术平均值这一概念的认识。如果N个数的算术平均是X,则这N个数之和为NX。只要掌握了这一点对于那些考察算术平均值的题目就应该迎刃而解了。从这里我们也可以看出在改革后的GRE数学中,对于一些统计学数值(比如算术平均、极差、标准方差、中数等)的理解要求提高了。

  多项选择题

  例:In triangle ABC,the measure of angle A is 25 and the measure of angle B is greater than 90. Which of the following could be the measure of angle C­

  Indicate all possible values.

  A. 12 B. 15C. 45  D. 50 E.70

  本题考察的是三角形的基本性质:内角和等于180度。由题意可知角A角B之和大于115度,由此可以得出A、B、C、D为正确答案。

  上述就是对于GRE数学考试难点成功突破技巧的详细说明,希望可以供大家参考,更好地备考新GRE数学。由于GRE数学本身考察的数学知识并没有变难,所以这种题型仅仅是增加了考生思维的复杂性,并要求考生更加细心。小编在此预祝大家在考试中取得优异的成绩。
