初中学生在逻辑思维方面有一个具有一定普遍性的缺陷:在研究多个对象组成的整体的性质时,常把“很大部分是”错误地当成了“都是”;或者把“很小部分是”和“常见部分不是”错误的断言为“不是”。这类错误,可名之曰:“忽视特例”。此处“特例”一词,具有双重的意义,就数量而言,它指个别对象的性质;就接触情况而言,它指很少接触的对象的性质。 Junior high school students have a certain general flaw in their logical thinking. When studying the overall nature of multiple objects, they often mistake “largely” as “all”; or “a small part Yes ”and“ common part is not ”wrong assertion as“ no ”. This type of error, you can name it: “ignore special cases.” The term “special case” here has a dual meaning. In terms of quantity, it refers to the nature of individual objects; in terms of contact, it refers to the nature of objects that are rarely touched.
