推断题是以元素化合物知识为主,集基本概念和基本理论为一体,通过严密的逻辑推理而得出正确结论的综合性题目.它具有显著的学科特点,能较全面地考查学生对原子结构、元素及化合物知识的掌握情况,同时还具有知识面广、综合性强、题型多、思维容量大等特征,所以它又能考查学生的逻辑思维、整体思维及知识联想与迁移的能力.推断题可分为元素推断题(主要在高中学习)和物质推断题.根据题给条件的表达形式,又可分为文字叙述推断题、框图推断题、表格推断题和实验推断题等.
Extrapolation questions are based on the knowledge of elemental compounds, which integrates the basic concepts and basic theories and concludes the correct conclusion by rigorous logical reasoning.It has the characteristics of significant disciplines and can comprehensively examine students’ , Elements and compounds of knowledge, but also has the characteristics of a wide range of knowledge, strong comprehensiveness, multiple questions, large thinking capacity, so it can examine students’ ability of logical thinking, holistic thinking and knowledge association and migration. Inference questions can be divided into element inference questions (mainly in high school) and matter inference questions.According to the expression of the conditions given, can be divided into text description inference questions, block inference questions, form inference questions and experimental inference questions.
