从一节语文公开课的一个小插曲中出现的一个断句问题出发,分析了学生在教师反复导读下依然读破句子的原因,阐述了小学语文课堂补充汉语基础语法知识的必要性并提出了相关建议。汉语语法相关知识的认知应该从小学抓起,教师在处理语法问题的时候更应该直面而不是回避。 Based on the problem of a sentence break in an episode of a Chinese open lesson, this paper analyzes the reasons why the students still read the broken sentences under the repeated guidance of teachers, expounds the necessity of supplementing the basic grammar knowledge of Chinese in primary Chinese classrooms and puts forward the related Suggest. Chinese grammar-related knowledge of cognitive should start from primary school, teachers should deal with grammar issues more than face directly rather than avoid.
