问题 问答题 简答题

某同学调查三年来某校(系二级达标中学)高三生参加省会考的情况,发现所有学生都通过了会考,进而得出结论:二级达标中学的学生全部都可以通过省会考。请根据完全归纳推理的条件,说明这个结论必然正确吗?如果是错误的,那么,必然正确的结论是什么?

答案

参考答案:

这个结论不是必然正确的。一个正确的完全归纳推理必须满足两个条件:一是每一个前提都必须是真实的,二是所涉及的对象一个都不能遗漏。某同学调查的范围只是三年来某校所有的高三生参加省会考的情况,并没有穷尽该校所有年度的高三学生,更没有穷尽所有的二级达标中学所有年度的高三学生。所以,“二级达标中学的学生全部都可以通过省会考”这个结论是通过不完全归纳推理得出的,是或然性结论,不是必然正确的。运用完全归纳推理得出的必然正确的结论是:该校三年来的高三学生全部通过了省会考。

解析:

【考点】树立科学思维的观念

【分析】本题考查完全归纳推理的条件。解题时要根据完全归纳推理的条件,说明这个结论不是必然正确的,然后写出必然正确的结论。

【点评】有一定的难度。
