笔者在2016年写了“有关定量测定的高考题考查方式归类解析”一文,专门剖析定量测定且预测命题趋势,在《高中数理化》杂志发表。研究2017年高考化学试题后,感觉面貌一新却又似曾相识,现从熟题来源、2017年预测、新题呈现、2018年备考指导等方面归纳小结,仅供参考。一、熟题新说,促进知识正迁移有元素化合价发生变化的反应称为氧化还原反应,特征是元素化合价升降总数相等,实质是电
The author wrote in 2016, “Quantitative Determination of the entrance exam test classification analysis,” a text, specifically analysis of quantitative determination and forecast proposition trend, “high school mathematics and chemistry” magazine. After examining the 2017 college entrance examination chemistry exam, I feel a new but familiar demeanor. The summary is summarized from the sources of mythical questions, the forecast of 2017, the presentation of new questions, and the preparation of exams in 2018, which are for reference only. First, the new theory, to promote the knowledge transfer There is a change in elemental valence reaction is called the redox reaction, characterized by the same elemental valence lift the total number of equal, in essence, electricity
