全国各地中考数学试题中,有不少题目是源于课本的。在数学总复习中坚持“以本为本”的方针,抓好基础知识和基本技能的训练,发挥教材例题和习题的作用,这无疑是提高教学质量的重要环节。 Many of the topics in the mathematics tests in the national examinations across the country are due to textbooks. In the general review of mathematics, we adhere to the “base-oriented” approach, do a good job of basic knowledge and basic skills training, and use the examples of textbooks and exercises to play a role. This is undoubtedly an important part of improving teaching quality.
