2011年8月，ETS如约实现了造势良久的“迄今最大的变革”。同月1日，新GRE在大陆正式开考。接下来的8月到10月是新GRE考试的磨合期，11月下旬开始进入正常轨道。GRE新一轮的改革旨在使该考试变得更为公平。改革后，GRE考试频率也由之前的一年两次变为每个月一到两次，由此，学生的选择更多也更自由。

In August 2011,ETS for the realization of the power for a long time"So far the biggest change".Month 1,The new GRE on the mainland started.The next August to October is the new GRE test running in period,Late November began to enter into the normal track.GRE a new round of reform aims to make the examination more fair.After the reform,The GRE general test frequency also before by twice a year into each month one to two times,this,The choice of students more and more free.

　

　一、数学改革总述 a/Mathematics reform an overview

　　在数学方面，总的来讲：题型变化较大，难度稍有提高，而知识点的范围基本不变。变革后，数学部分共两个section（不考虑加试），每个section要求在35分钟内完成20道题目。

In mathematics,generally:Topic changes greatly,Difficulty slightly improve,The scope of knowledge and basically unchanged.Change after,The math part of the common two section(Don't consider add try),Each section requirements in 35 minutes to finish 20 questions.

　　其中，按照OG（Official Guide）中的说明以及过去一年实际考试的试卷总结，每个section的题型和题量分布大致如下：

the,According to the og(Official Guide)Over the past year the description and actual exam papers summarize,Each section of the topic and the topic quantity distribution roughly as follows:

　　

　　二、题型分析 two/Topic analysis

　　从题型角度，数值比较和单选题都是传统考题，考察的知识较为简单；而且，选择题的形式，决定了我们可以利用选特殊值、代选项等特殊手段获得正确的答案。需要注意的是，数值比较大小这种题型，有一种默认的选项设置，我们可以通过例1了解一下：

From the Angle of the topic,Numerical comparison and single subject are traditional examination questions,The investigation of knowledge is relatively simple;and,The form of choice,We can choose to use special value/Generation of options and other special way to get the right answer.Need to pay attention to is,Numerical comparison size this topic,There is a default option Settings,We can through the example 1 about:

　　例1： Quantity A Quantity B

Ex 1: Quantity A Quantity B

　　X^2+1 2x-1

X ^ 2 + 1 2 X - 1

　　解析：按照默认的选项设置：选择 A 表示Quantity A is greater，选择 B 表示Quantity B is greater，选择 C表示The two quantities are equal，而选择 D 表示The relationship cannot be determined from the information given。知道了这个之后，我们通过两个量作差（x^2+1-(2x+1)）的方式，可以轻松选出正确答案。

analytic:According to the default option Settings:Choose A said Quantity A is greater,Option B said Quantity B is greater,Choose C said The two quantities are equal,Choose D said The relationship cannot be determined from The information given.Know the later,We through the two quantity for difference(X ^ 2 + 1 -(2 x + 1))way,Can easily choose the right answer.

　　在解决数值比较大小和单选题的过程中，尽量避免冗余的计算，通过作差作商、代入选项等方式快速得到答案。同时，必须要有一个意识：数学试卷中的几何图形，往往不是按照比例画的。因此不能直接从图形中判断线段的相对长短或者某个角是否为直角。比如下面一个例子例2，正确的答案应该是D：cannot decide：

In solving numerical comparison size and single selection process,Try to avoid redundant calculation,Through making a difference for business/A generation in the way of fast to get the answer.At the same time,There must be a conscious:The geometric figure the math exam,More often than not, according to the proportion of the painting.So can't directly from graphics for judging the relative length line or a certain Angle whether for right Angle.For example below a example 2,The correct answer should be D:Cannot decide:

　　例2：

Ex 2:

　　多选题和计算题是新G新增加的题型，这也是新G数学部分最大的变化所在。两种题型的设置，都要求学生能够在没有太多选项提示的情况下，自主得到可能不止一个的正确答案。此外，题目背景的设置更为生活化，即可能引入一些生活场景的描述，学生要能够通过语言关，从一堆信息中抽取有用的数学做题信息。

Many topics and calculation problem is the new G additional questions,This is the new G the math part is the biggest change.Two questions Settings,Require students to without much option suggestive cases,Independent get may be more than one answer is correct.In addition,Topic background Settings more life,Namely may introduce some life scene description,Students to be able to pass through language,From a heap of information extraction of useful math do topic information.

　　以下分别给出一道多选题（例3）和一道计算填空题（例4）的例子：

The following are given a multiple-choice questions(Ex 3)And a calculation fills up the topic(Example 4)example:

　　例3：

Ex 3:

　　解析：这道题便是一道典型的多选题，题目不难不给出详细解题过程了。仅仅给出几个解决多选题的注意事项：1、从题目的描述中决定正确答案的个数，比如这里明确说明“选出两个”，而更多地题目中是没有这个限制的，因此答案的个数是任意的。2、某些题目中，利用不等式关系计算出正确答案的范围，提高做题速度和命中率，比如曾有真题，要求从6个选项中，选出可以作为三角形第三边的数字。显然，我们可以通过“两边之和大于第三边，两边之差小于第三边”迅速敲定范围，再进一步选定正确选项。

analytic:This problem is a typical multiple-choice questions,It is not difficult to topic not given the detailed problem solving process.Just give a few solve the matters needing attention in the title:1/From the topic description to the number of the right answer,Such as specified here"Selecting two",And there is no more questions in this limit,So the number of the answer is arbitrary.2/Some questions in,Using inequality relationship calculated the range of the right answer,Improve do topic speed and shooting,For example there have been really writes,Requirements from six options,Choose can be used as a triangle the third side of the digital.obviously,We can through the"The sum of both sides were greater than the third side,The difference on both sides is less than the third side"Quickly finalized range,Further select correct option.

　　例4：

Example 4:

　　解析：这道题是一道计算填空题，要求学生根据题目做出正确答案后，直接填在空格处。解决此类题目时候，需要看清题目中的要求，看是否要求保留几位小数等。令人欣慰的是，新G考试的数学部分，增加了屏幕计算器，平时可以通过模考软件熟悉下计算器的使用。

analytic:This problem is a calculation fills up the topic,Students are required to according to the topic to make the right answers,Directly fill in the gaps.To solve such topic time,Need to see the requirements of the subject,See whether to ask keep several decimal, etc.It is encouraging to see,The math part of the test new G,Increased screen calculator,At ordinary times can through the die test software be familiar with the use of calculators.

　

　三、知识点分析 three/Knowledge analysis

　　从知识点角度，新GRE数学部分的考察，相对于之前内容基本不变，大多数为初中内容，少部分涉及高中内容。学生可以通过OG的第七章Math Review温习下可能考到的知识。注意，此章节为考点的详尽无遗漏列举，因此只要看过一遍，至少能保证考点的全部覆盖。

From the Angle of knowledge,The new GRE the math part of the investigation,Relative to the same basic content before,Most for junior middle school content,A few involved in high school content.Students can through the og chapter seven Math Review Review may take an examination of the knowledge.note,This section for detailed examination site complete list,So as long as seen again,At least can guarantee that all the test coverage.

　　考点分为四章，分别为：Arithmetic（算术）、Algebra（代数）、Geometry（集合）、Data analysis（统计）。其中，第四章为重点和难点，其中涉及的某些数学概念，比如quartile；和某些知识点，比如正态分布等数学统计知识，可能某些省市的高中数学或者某些高校的高等数学课程中并未涉及。这部分，内容较多，概念、公式都不少，相对也容易出现复杂繁琐的题目，以图形统计类题目为代表。因此，务必认真看完这个部分的知识点总结，并且花大力气多做这部分的习题，强力攻克之！

The examination site is divided into four chapters,respectively:Arithmetic(arithmetic)/Algebra(algebra)/Geometry(set)/Data analysis(statistics).the,The fourth chapter as the key point and the difficulty,Some of the math concepts involved,Such as quartile;And some knowledge,Such as normal distribution and mathematical statistics knowledge,May be some provinces and cities of high school mathematics or some college of higher mathematics course did not involved.This part of the,Content more,concept/Formula are many,Relative also easy to appear complex trival topic,To graph statistics class title as a representative.therefore,Be sure to carefully read this part of knowledge summary,And take great effort to do more this part of the problem,Strength to conquer the!

　　前三章内容貌似简单，但也有出难题的可能，尤其算术。这也是为什么有为青年的大学生也没有十足的把握解决所有的小学数学奥赛题。给大家的建议是：做完“猴哥112题”和“难题105”（可百度下载之）。

The first three chapters content seemingly simple,But there are also the problems may,Especially arithmetic.This is why promising young college students also have no real grasp solve all the elementary school mathematics olympiad question.To everyone's advice is:finished"The monkey elder brother 112 questions"and"105 problems"(But baidu the download).

　　最后，强烈要求大家背好常用的GRE数学词汇。这是最基础最重要的一个环节，唯有做好这个环节，才算是符合了参加GRE数学考试的最低基本要求。

finally,Urge everyone back good common mathematical GRE vocabulary.This is the most basic one of the most important link,Only doing this link,It is in accord with the GRE math exam minimum basic requirements.

　

　四、难度分析 four/Difficulty analysis

　　新GRE考试全部采取机考，而且增加了一个难度调整的机制，即各个section之间的难题自适应（adaptive）调整：第一个section正确率高，第二个就加大难度；反之，降低难度。这一改革之后，大多数的大陆考生面对相同的问题，第二个section的题目普遍要比前一个难很多。但是，这里所说的难只是相对的。即使是最难的题目，对于延续着中华民族优良血统的中国考生来讲，这种绝对难度都是可以突破的。大家可以从OG给出的数学题中，确认这一点，并找到信心。

The new GRE all adopts machine tests,And added a difficulty adjustment mechanism,That is the problem of each section between adaptive(adaptive)adjustment:The first section of high accuracy,The second will increase the difficulty;and,Reduce the difficulty.After this reform,Most of the mainland examinee face the same problem,The second section of the common topic than previous difficult many.but,What say here is relatively difficult.Even if is the most difficult subject,To the continuation of the Chinese nation with good pedigree for Chinese students,This absolute difficulty is breakthrough.You can from og given in the math problem,Confirm this,And find the confidence.

　　

五、复习建议 five/Revision Suggestions

　　GRE数学部分跟语文部分一样，总分170；但是，题目更简单，题目数目更少，时间更充足。因此，所有人都应该努力获取满分。

The math part of the GRE with Chinese as part,The total score of 170;but,Subject more simple,Title number less,More enough time.therefore,All people should try to get full marks.

　　分析以往考生没有获得满分的原因，主要有以下几点：1、英文理解能力较差，无法理解题意；2、数学术语不懂；3、考点遗忘；4、读题疏漏；5、做题粗心。

Analysis of previous candidates don't get full marks reason,Mainly has the following points:1/English comprehension ability is poor,Can't understand cet4;2/Mathematical terms do not understand;3/Examination site forgotten;4/Read question omissions;5/Do topic careless.

　　针对这种现象，要求大家做到以下几点：1、数学术语和知识点温习；2、定期全套试卷；3、难点突破：图表、统计类多加练习；4、良好心态。

Aiming at the phenomenon,Everyone to do the following:1/Mathematical terms and review of knowledge;2/Regular full set of papers;3/Difficulties breakthrough:chart/Statistical class practice;4/Good attitude.

　　可作为联系和模考的资料，主要有：OG、绿皮书，参考网络资源：《猴哥112题》、《105难题》、陈向东《数学高分突破》。更多精彩讲解和分析，详见上海新东方强化班和数学专项班。

Can be used as connection and die take an examination of material,Mainly has:og/Green paper,Reference network resources:[The monkey elder brother 112 questions]/[105 problems]/ChenXiangDong[Mathematics high scores breakthrough].More wonderful explanation and analysis,See Shanghai new Oriental intensive training class and mathematics special class.

　

　六、总结 six/summary

　　GRE数学很重要，跟Verbal部分平分江山。但是，数学毕竟不是GRE这门考试的真正难点所在，可以在考试之前一个月集中突破下，而更多地精力应该花在Verbal部分的准备。请同学们按照自己的实际情况，选择合适的复习备考策略，一次性获得比较理想的GRE成绩！

GRE mathematics is very important,With Verbal part divide the jiangshan.but,Mathematics is not after all GRE this exam real difficulty,Can one month before the exam under concentrated breakthrough,And more energy should be spent on Verbal part of the preparation.Please students according to their own actual situation,Choose appropriate review for information strategy,One-time get ideal the GRE general test!
