本文就新GRE数学考试固定规律做介绍,希望可以给大家提供一些参考。 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 appearjagged can also be assumed to be straight : Figures are intended to provide useful information for answering the questions. However,except where a figure is accompanied by aNote 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ETS 出题原则,即: 所有的数都是实数; 除非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; 伴随问题的图形将为解题提供有用的信息。但是,只有在问题中指出本图形是按比例画出时,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。 |
