GRE 数学出题原则

  1. 实数原则

  All numbers used are real numbers;

  所有的数都是实数;

  2. 同一平面原则

  All figures lie on a plane unless otherwise indicated;

  除非GRE数学题目中专门指出假设所有图形都在同一个平面内;

  3. 正角度原则

  All angle measures are positive;

  所有的角的测量值都是正数;

  4. 默认直线原则

   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);

  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”);

  5. 图形只读原则

   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.

   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。
