字词教学是语文教学的基础。但长期以来，我们没有量化的分析，哪些字该教，什么时候教，全凭经验。教学双方都缺少全局的把握。现在，李镗先生在大量详实的数字统计基础上，首次为我们提供了一个全面了解初中字词分布的机会。本刊将分期连载这一成果，希望能以此支持中学语文教学工作的改进。 Word teaching is the basis of language teaching. However, for a long period of time, we have not quantified the analysis. What words should be taught and when to teach depends entirely on experience. Both sides of the teaching lack the overall grasp. Now, based on a large number of detailed statistics, Mr. Li has provided us with an opportunity to fully understand the distribution of junior high school words for the first time. This publication will serially serialize this achievement and hopes to support the improvement of Chinese language teaching in middle schools.
