下面是小编为大家整理的gre数学考试出题原则，本文共6篇，如果喜欢可以分享给身边的朋友喔!
篇1：gre数学考试出题原则
gre数学考试出题原则你清楚吗?
在gre数学考试中，一般都假定以下信息为真：
●All numbers used are real numbers;
●All figures lie on a plane unless otherwise indicated;
●All angle measures are positive;
●All lines shown as straight are straight. On the computer-based test， lines that appear“jagged“ can also be assumed to be straight (lines can look somewhat jagged on the computer screen)：
●Figures are intended to provide useful information for answering the questions. However，except where a figure is accompanied by a“Note” stating that the figure is drawn tO scale， solve the problem using your knowledge of mathematics， not by visual measurement or estimation.
细心的读者会发现，上述假设实际上就是gre数学考试出题原则，即：
●所有的数都是实数;
●除非gre数学考试题目中专门指出假设所有图形都在同一个平面内;
●所有的角的测量值都是正数;
●所有显示为直线的线均可当作直线来处理(在机试中，因为电脑显示器的原因，直线可能会看起来呈“锯齿状”);
●伴随问题的图形将为解题提供有用的信息。但是，只有在GRE数学的问题中指出本图形是按比例画出(drawn to scale)时，才可以用目测或估计而得到的信息去解题。否则，只能运用你的数学知识去回答问题。这一解题原则可以简称为“只能读图，不能度量”的原则。
GRE阅读高分备考的重点
一：有一定的词汇量
GRE阅读所需掌握的单词要少的多，这些词往往都是些GRE阅读专属词汇，且重复率很高，只需集中背记一下就可以解决基本问题。
二：选答案有方法、有技巧
GRE阅读的答案的确是有一些特点的。有一些答案一看就是正确答案，说得客观严谨、小心翼翼，有的一看就是错的，这里面包含一些特定的规律。
三：对句子有基本的理解能力
GRE阅读有很多阅读技巧，但它只是一种锦上添花的东西，要在你对文章的大意甚至对一些具体的内容有一定的理解的基础上才能发挥作用，而这个基础就体现在对句子的理解上。
四：熟悉考点和题型
GRE阅读考了很多年，已经呈现出了明确、固定的出题点和试题类型，考生应该对它们有充分的了解。
五：智慧读原文
要靠读懂全文来做对题，对中国考生来说是一件很难的事情，即使把文章全部翻译成中文，也很难在如此短的时间内逐字逐句理解全文，更何况是生词连篇、复杂难懂的英文，所以我们要靠快速读文法，学会抓重点。
六：考点详细读，非出题点略读
这句话非常简单，然而，很多考生往往很难做到这一点，有的考生是不知道什么有用，不知道哪儿是出题点，也就不知道哪里详读哪里略读，只好全文都一样重点的读，其实也就等于全文都没读好。
GRE阅读材料：鸟叫的研究
Over the years, biolists have suggested two main pathways by which sexual selection may have shaped the evolution of male birdsong. In the first, male competition and intrasexual selection produce relatively short, simple songs used mainly in territorial behavior. In the second, female choice and intersexual selection produce longer, more complicated songs used mainly in mate attraction; like such visual ornamentation as the peacock’s tail, elaborate vocal characteristics increase the male’s chances of being chosen as a mate, and he thus enjoys more reproductive success than his less ostentatious rivals. The two pathways are not mutually exclusive, and we can expect to find examples that reflect their interaction. Teasing them apart has been an important challenge to evolutionary biolists.
Early research confirmed the role of intrasexual selection. In a variety of experiments in the field, males responded aggressively to recorded songs by exhibiting territorial behavior near the speakers. The breakthrough for research into intersexual selection came in the development of a new technique for investigating female response in the laboratory. When female cowbirds raised in isolation in sound-proof chambers were exposed to recordings of male song, they responded by exhibiting mating behavior. By quantifying the responses, researchers were able to determine what particular features of the song were most important. In further experiments on song sparrows, researchers found that when exposed to a single song type repeated several times or to a repertoire of different song types, females responded more to the latter. The beauty of the experimental design is that it effectively rules out confounding variables; acoustic isolation assures that the female can respond only to the song structure itself.
If intersexual selection operates as theorized, males with more complicated songs should not only attract females more readily but should also enjoy greater reproductive success. At first, however, researchers doing fieldwork with song sparrows found no correlation between larger repertoires and early mating, which has been shown to be one indicator of reproductive success; further, common measures of male quality used to predict reproductive success, such as weight, size, age, and territory, also failed to correlate with song complexity.
The confirmation researchers had been seeking was finally achieved in studies involving two varieties of warblers. Unlike the song sparrow, which repeats one of its several song types in bouts before switching to another, the warbler continuously composes much longer and more variable songs without repetition. For the first time, researchers found a significant correlation between repertoire size and early mating, and they discovered further that repertoire size had a more significant effect than any other measure of male quality on the number of young produced. The evidence suggests that warblers use their extremely elaborate songs primarily to attract females, clearly confirming the effect of intersexual selection on the evolution of birdsong.

(A) showing that intrasexual selection has a greater effect on birdsong than does intersexual selection
(B) contrasting the role of song complexity in several species of birds

17.5. The passage indicates that researchers raised female cowbirds in acoustic isolation in order to
(A) eliminate confounding variables

(A) uses songs mainly in territorial behavior
(B) continuously composes long and complex songs
(C) has a much larger song repertoire
(D) repeats one song type before switching to another
(E) responds aggressively to recorded songs
17.7. The passage suggests that the song sparrow experiments mentioned in lines 37-43 failed to confirm the role of intersexual selection because
(A) females were allowed to respond only to the song structure
(B) song sparrows are unlike other species of birds
(C) the experiments provided no evidence that elaborate songs increased male reproductive success
(D) the experiments included the songs of only a small number of different song sparrows

篇5：GRE数学考试心得
参加完了GRE考试之后，我发现新GRE数学考试既考察学生的数学能力，也同时考察学生对专业术语的认识和运用。两厢结合，GRE数学考试的时间就有些紧。很多同学GRE数学分低不是因为能力不够，而是没有把握好时间做题。
所以，我们对GRE数学考试时间的把握是十分重要的，如果GRE考试时时间不够该怎么办呢?要解决时间不够问题的问题，还是需要我们熟悉GRE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，而不用再去想：题目这么说，到底是什么意思呢?达成这一能力的唯一途径也只能是多做题。即使觉得自己的数学基础不够，书本和教材里面的3000+题目也够提升这一能力了。
例如，我们来看一个题目：The vertices of an equilateral triangle are on a circle.
The length of a side of the triangle The diameter of the circle
在拿到题目的时候就应该在脑海中形成这样一个图像：一个等边三角形内接在一个圆里面。那么所有的数值都可以算出来，先不要看题目，我们心算出圆的'半径和等边三角形的一个边的关系：1：3，其他关系，比如三角形和圆面积的关系也可以都算出来，这时候再来看题目的两个题肢：三角形一个边的边长，和圆的直径，他们的比值就是3：2，也就是1.732: 2 那么很显然就是选B。
篇6：GRE阅读出题特点
全面了解GRE阅读出题特点和文章题型细节基础知识
GRE阅读出题形式简介
GRE阅读大量模仿了GMAT逻辑题的出题方式。一言以蔽之：新GRE阅读 = 老GRE阅读 + GMAT逻辑。
GRE阅读中在保留了老GRE长文和短文的基础上，还增加了只有一到四句话的超短文章，称之为微文。微文虽然微小，但极具逻辑。
GRE阅读基本题型讲解
新GRE改革后语文部分做出了调整，而新GRE阅读理解题包含三种题型：
五选一( Multiple-choice Questions—Select One Answer Choice )
三选多( Multiple-choice Questions—Select One or More Answer Choices )
句子功能题( Select-in-Passage )
其中第一种“五选一”就是目前GRE阅读的题型。而第二种“三选多”(从三个选项中选出所有适合的答案，正确答案数不定，只选出部分正确答案者 不得分)与第三种“句子功能”题(找到原文中与选项描述相一致的句子并点击该句子)都是阅读理解部分新增的题型。对于新GRE语文部分的内容考生不用慌 张，主要还是对单词和阅读的把握。
GRE阅读题在考试中如何出现?
新GRE阅读中,目前已出现的两种情况：
(1)一个Section有4篇文章,均为短阅读,长度约为150~180字左右,每篇题目数量依次为3道,2道,2道,2道,总的题目数量为9道,此时逻辑题为1道.
(2)一个Section有3篇文章,1篇为长阅读,长度约为400~500字左右,题目数为4道,另附2篇短阅读,题目数依次为1道和3道,总共题目数为8道,此时逻辑题为2道.
个人观点：在每个Verbal Section中最多一篇长阅读,由于时间限制的原因,这在超时的OG和限时PP软件上的套题中均有所体现.在题型方面,相较于旧GRE传统的5选1题型,新G在5选1题型基础上,新增了句子选择题以及三项多选题.
总体而言,从文章的难度上,新GRE并没有改变旧GRE文章深奥、句子复杂等特点,同时在题型上注重对于文章具体句子和词汇的考察,也延续了对于文章中事物逻辑的考察,文章主题的把握.文章长度上的整体缩短,但是在题量上的增加,会导致阅读难度不断加大.
GRE阅读文章有哪些特点?
1. 按题材分：文学评论, 美国历史, 弱势群体, 生命科学
2. 按写作方法分：presentation[立论], argument[评论]
3. 按写作套路分：新旧观点型、现象解释型、结论解释型、问题解决型

GRE阅读题目具体分析
长文章：我2分钟读完,知道大概是讲大气成分(二氧化碳和m)与气温的关系。不再多想，做题目：
1.主题。简单。
2.定位至4段，因为定位局限，因此可以使用选项定位法(如果定位范围很广则直接跳过)。
(a)看到marine，凭印象也知道4段没有讲，错。
(b)刚好是刚才注意到的语言现象(转折although).
(c)找twice定位。比较范畴错。
(d) 有印象的话这种结构只在第二段出现过，错。
(e)看到most马上就知道错，不仅仅是本段，即使放在全文也没有出现过最高级，至出现了大量的比较级，而比较级中没有出现过than any这样的字眼，因此最高级必错。
3.定位至二段。
三个语言现象。大概心里有数，直接看选项：
(a)虽然有比较，但是这种比较没有先后因果的概念。错。
(b)only未出现过。错。
(c)如果不能马上判断，先跳过。
(d)无比较。错。
(e)标准改写。(语言现象：重大转折although)
4.明确定位的题目。简单，只说选项缩读：
(b)simulation model为4段内容。
(d)(e)benefit/benefitial莫名其妙。并且(e)中的have been found原文中没有。
5.6.属于可以错的题目，因为没有明确定位，而没有明确定位的题目具有很大偶然性，我当时一看题目，感觉两个题目都象是取非题但又无法定位，就直接跳过做第7题了。这个取舍过程花了1分钟不到的时间。虽然本文的这两个题目还算不难，凭背景知识也可以做对，但是不能保证考场上也有这样幸运的题目，并且在当时(91年)可能这也算比较新颖的知识。因此错了绝对可以，我是给自己这样的允许的。但是象上面的4个题目和下面的第7题是绝对不能错的，我们平时练习的最终目的就是保证这些题目的正确率。这2个题目的解题方法不讲，一来我没有思考(我从来不思考这些难度题目)，二来感觉不具有普遍性。
7.结构题，简单，略。
总结：文章不难，题目也不难，就是时间紧张，尤其在考场上更会是如此。文章读个大概就可以了，题目有取舍有先后顺序有大体原则(刚才演示过了)。
短文章：
首句：作者说了arrom这个人说了个女人地位的评价。好，我们关注的就是作者对这个人所做评价的评价。
二句：语言现象：比较级+排比句+转折(while后置了)
三句：似乎是一个虚拟语气，不多想，放在这里。
四句开始：很明显的作者的评价，最最重要的地方，要读懂。
8.主题：只说缩读：
(b) 先不管到底这句话对不对，至少一眼要能看出这是细节内容，错。
(c) 看到explain就知道错了。
(d)看到reject就知道错。
(e)看完后，1790错。
9.明确定位，简单，略。
10.题目提示agree，大概回想到前面的排比句里面找。
11.简单，(d)(e)看到首词即可知道错误。
总结：坚持这样的思路下来，本练习的11个题目里面对8-9个是完全应该的，除了长文章的5，6题不计入应该对的题目之外，其它题目都是应该掌握的，判断标准：能不能定位明确。
