近几年来,化学试题的命题素材具有广泛的实际应用背景,命题者常常有意地在试题中将实际应用背景跟化学核心内容有机地结合在一起。这种命题意向告诉我们,在高考复习中要重视以下两个方面:第一,要重视从化学学科角度对主干知识、核心内容加以总结梳理;第二,要重视理论联系实际,提高用化学基础理论观察分析实际问题的能力。现选几道典型试题加以剖析,供参考。
In recent years, the propositional material of chemical test questions has a wide range of practical applications. Propositioners often deliberately combine the actual application background with the chemical core content in the test questions. This propositional intention tells us that we should pay attention to the following two aspects in the review of college entrance examinations: First, we must pay attention to summarizing the main knowledge and core content from the perspective of chemistry; Second, we must attach importance to integrating theory with practice and improve the use of chemical basis. Observe theoretically the ability to analyze actual problems. Several typical test questions are selected for analysis.
