GRE数学考试对中国考生来说可以算是加分项,因为题目本身难度并不高。 GRE数学官方5大出题原则之实数原则 All numbers used are real numbers; 所有的数都是实数; GRE数学官方5大出题原则之正角度原则 All angle measures are positive; 所有的角的测量值都是正数; GRE数学官方5大出题原则之默认直线原则 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”); GRE数学官方5大出题原则之同一平面原则 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; GRE数学官方5大出题原则之图形只读原则 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。 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。 (责任编辑:admin) |
