一、高考试题的特点1.题型稳定:近几年来高考解析几何试题一直稳定在三个选择题、一个填空题、一个解答题上,分值约为30分左右,占总分值的20%左右.2.整体平衡、重点突出:《考试说明》中解析几何部分理科有39个知识点(从1999年开始降为36个知识点),一般考查27至32个,文科有31个知识点,一般考查22至26个,考查的覆盖面广.以理科为例,对直线、圆锥曲线、极坐标、参数方程的知识的考查几乎没有遗漏,通过对知识的重新组合,重点考查求曲线方程及直线与圆锥曲线关系问题,并以这些知识为载体,突出了对三基、能力及数学思想方法的考查.3.难度下降、位置不定:近几年来解析几何试题难度有所下降,以1998年理科试题为例,三道选择题的难度系数分别为0.829、0.607、0.699,一道填空题的
First, the characteristics of the high test questions 1. Question type stability: In recent years, the analytical geometry of the college entrance examination questions have been stable in three multiple choice questions, a blank answer questions, a solution question, the score is about 30 minutes or so, accounting for 20 of the total score % or so.2. Overall balance and focus: In the “Exam Description”, there are 39 knowledge points in the analytical geometry (from 1999 to 36 knowledge points), 27 to 32 general examinations, and 31 knowledge in liberal arts. In general, from 22 to 26 examinations, the examination coverage is wide. Taking science as an example, the examination of the knowledge of straight lines, conic curves, polar coordinates and parametric equations is almost omission. Through the recombination of knowledge, the focus is on the search for the curve equations. And the relationship between straight lines and conic curves, and using these knowledge as a carrier, highlights the examination of the three bases, abilities, and mathematical thinking methods. 3. Difficulty and indefinite positions: The difficulty in parsing geometric tests has declined in recent years. In the case of scientific examinations in the year, the difficulty coefficients of the three multiple-choice questions were 0.829, 0.607, and 0.699, respectively.
