高考数学试题中,选择题注重多个知识点的小型综合,渗透各种数学思想和方法,体现以考查“三基”为重点的导向,能否在选择题上获取高分,对高考数学成绩影响重大.本文将从解题技巧方面谈谈选择题的做法.法1:直接法直接从题设条件出发,运用有关概念、性质、定理、法则和公式等知识,通过严密的推理和准确的运算,从而得出正确的结论,然后对照题目所给出的选择支“对号入座”作出相应的选择.
In the math test, the multiple-choice questions focus on the small-scale synthesis of multiple knowledge points, infiltrating various mathematical ideas and methods, and embodying the orientation of examining the “three bases” as the key points, and obtaining the high scores on the multiple-choice questions. Mathematics results have a great impact.This article will talk about the multiple-choice practice from the aspects of problem-solving skills.First law: direct method directly from the title conditions, the use of the concepts, nature, theorems, rules and formulas and other knowledge, through rigorous reasoning and Accurate calculations to arrive at the correct conclusion, and then make the appropriate choice given by the selection of the subject “condemnation ”.
