初中化学描述性知识多，推理性知识少，中考化学试题也是对知识考查得多，即便是推理性知识也只是将几个知识点按照一定的形式综合起来，没有过多过深的思维技巧。所以，复习时应加强基础知识教学，重视发展学生智力，培养学生的能力和学习方法，注重提高学生思想品德素质... Junior middle school chemistry has more descriptive knowledge and less reasoning knowledge. The chemistry examination questions in the examination are also much more knowledge-reading. Even the reasoning knowledge only integrates several knowledge points according to a certain form without too much thinking skills. Therefore, during the review, we should strengthen the teaching of basic knowledge, attach importance to the development of student intelligence, develop students’ abilities and learning methods, and pay attention to improving students’ ideological and moral qualities.
