古人习惯于把文章的条理叫“序”,并把“有序”作为写文章的两个基本要求之一。这就从一个侧面告诉人们,准确地把握文章的“序”,是读懂读通文章的基本方法之一。《团结广大人民群众一道前进》这篇文章(以下简称《团》文),条理井然,逻辑严密,因而把它作为论说文的典范(编入初中语文第五册),向学生传授议论的基础知识,实在是无可非议的,但是,近年来笔者两次讲授《团》文,总觉得分析吃力,课堂效果甚差。退而细思,以为关键就在于自己没有准确把握文章本身的“序”,以至于授课时纲不举,目不张, The ancients were accustomed to calling the order of the article “order” and “ordering” as one of the two basic requirements for writing articles. This tells people from one aspect that accurately grasping the “preface” of an article is one of the basic ways to read and read articles. The article “Unite the broad masses of the people together” (hereafter referred to as “the mission”) is well-organized and logical, so it is used as an example of the discourse (incorporated in the fifth grade of junior high school) to teach students the basis of argumentation. Knowledge is indeed beyond reproach. However, in the past two years, the author has given lectures on the “Tuan” twice. He always feels that the analysis is difficult and the classroom effect is very poor. Retiring and thinking carefully, the key is that he did not accurately grasp the “preface” of the essay itself, so that he did not give lectures when he taught.
