中学生的作文中,常常出现一些逻辑病句。对此,教师应结合教材中的逻辑知识,指出其错误的原因,使他们不仅“知其然”,而且“知其所以然”。 (一) 概念不明确一篇作文,首先要用准确的语言把思想感情表达出来。语言中的句子是由词或词组(短语)构成的。而每个词或词组都有确切的含义,这个含义就是人们常说的概念。概念分内涵和外延两个方面。概念的内涵是指事物的本质属性,即这个事物特有的、别的事物没有的东西;概念的外延是指概念所反映的那一类事物,即反映的事物的范围。所谓概念明确,就是要从内涵和外延两方面弄清楚。一、概念内涵不清。

This meaning is what people often say. The concept consists of two aspects: connotation and extension. The connotation of the concept refers to the essential attribute of the thing, that is, the thing that this thing has, and nothing else; the extension of the concept refers to the kind of thing that the concept reflects, that is, the scope of the thing reflected. The so-called concept is clear, it is necessary to clarify from the connotation and extension. First, the concept is unclear.
