  1. 新GRE數學考試出題原則

    發布時間:2017-11-13 編輯:bin

      GRE數學考試一直是GRE考試害怕的一個存在,其實GRE數學考試是有規律可循的,在GRE數學考試中,一般都假定以下信息為真:

      ●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.

      細心的讀者會發現,上述假設實際上就是ETS出題原則,即:

      ●所有的數都是實數;

      ●除非題目中專門指出假設所有圖形都在同一個平面內;

      ●所有的角的測量值都是正數;

      ●伴隨問題的圖形將為解題提供有用的信息。但是,只有在問題中指出本圖形是按比例畫出(drawn to scale)時,才可以用目測或估計而得到的信息去解題。否則,只能運用你的數學知識去回答問題。這一解題原則可以簡稱為“只能讀圖,不能度量”的原則 ;

      ●所有顯示為直線的線均可當作直線來處理(在機試中,因為電腦顯示器的原因,直線可能會看起來呈“鋸齒狀”) 。
