纵观历届各地中考试题中,计算型选择题所占比例较大,能否准确、快速地解好这类题,直接影响到考试的成绩.为了同学们能准确、快速地解决这类题,特把解决这类题的一些常用方法介绍如下,以供参考. 一、假设法有些题目由于题设条件不确定或题设条件模糊,造成计算困难.处理这类问题往往需要对不确定或模糊的条件进行假设,然后根据这种假设进行计算、分析、推理,从而求出正确的答案.
Throughout the examinations of various middle schools in the past, the proportion of computational multiple-choice questions is relatively large. Whether these questions can be solved accurately and quickly will directly affect the scores of examinations. For students to solve such questions accurately and quickly, Specifically, some common methods for solving such problems are described below for reference. First, some problems in the hypothesis method result in computational difficulties due to uncertain conditional conditions or ambiguous conditions. Handling such problems often requires uncertainty or blurring. The conditions are assumed, then calculated, analyzed, and reasoned based on this assumption to find the correct answer.
