出國(guó)留學(xué)網(wǎng)GRE欄目的小編給大家?guī)?lái)“如何尋找GRE數(shù)學(xué)規(guī)律快速做題”,以下是詳細(xì)內(nèi)容,希望對(duì)同學(xué)們有所幫助!
規(guī)律一:
在GRE(gre.zhan.com/)數(shù)學(xué)考試中,一般都假定一下信息為真。
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.
規(guī)律二:
細(xì)心的考G黨會(huì)發(fā)現(xiàn),上述假設(shè)實(shí)際上就是ETS出題原則,即:
所有的數(shù)都是實(shí)數(shù);
除非GRE數(shù)學(xué)題目中專門指出假設(shè)所有圖形都在同一個(gè)平面內(nèi);
所有的角的測(cè)量值都是正數(shù);
所有顯示為直線的線均可當(dāng)作直線來(lái)處理(在機(jī)試中,因?yàn)殡娔X顯示器的原因,直線可能會(huì)看起來(lái)呈“鋸齒狀”);
伴隨問(wèn)題的圖形將為解題提供有用的信息。但是,只有在GRE數(shù)學(xué)的問(wèn)題中指出本圖形是按比例畫出(drawn to scale)時(shí),才可以用目測(cè)或估計(jì)而得到的信息去解題。否則,只能運(yùn)用你的數(shù)學(xué)知識(shí)去回答問(wèn)題。這一解題原則可以簡(jiǎn)稱為“只能讀圖,不能度量”的原則。
以上就是關(guān)于GRE數(shù)學(xué)(gre.zhan.com/shuxue)考試中可以遵循的規(guī)律,希望對(duì)各位考生有所幫助。
