单项选择题,简称单选题。其结构分为两部分:题干和选项。选择题的目标就是通过某种方式去寻求未知部分的解决,即明确题干与选项的关系是否匹配,排除不匹配的选项,选取匹配的选项。要求同题干相匹配的选项有且只有一个,即匹配选项具有唯一性。作为数学知识的考查方式,单选题的题型结构特点决定了单选题的解题思路和解题方
Single choice, referred to as single choice. Its structure is divided into two parts: title and options. The goal of a multiple-choice question is to find a solution to the unknown part in some way, that is, to clarify whether the relationship between the question and the option matches, exclude the unmatched option, and select the matching option. There is one and only one option that requires matching, that is, the matching option is unique. As a test method of mathematical knowledge, the topic structure of the single-topic questions determines the problem-solving ideas and solving problems
