2．辩证的否定(1)辩证的否定是事物的自我否定。事物内部存在着肯定方面和否定方面，它们既对立又统一。最初，肯定方面处于支配地位，否定方面处于被支配地位。在这种情况下，事物就被肯定着。但是，在矛盾双方的斗争中，否定方面总会由弱变强。一旦否定方面由被支配地位上升为支配地位，事物就转化到了自己的对立面，实现了对事物的否定。事物最终之所以被否定，根源在于事物的内部，是事物内部的否定因素战胜了肯定因素。因此，事物的否定是自我否定。(2)辩证的否定是事物发展的环节和联系的环节。所谓发展，是指新事物的产生和旧事物的灭亡。而实现这一过程必须要对旧事物进行否定，否定实现了事物由旧质向新质的飞跃。新事物在否定旧事物时，并不是把旧事物全盘抛弃，一笔勾销。旧事物是新事物的母体，新事物从旧事物那里脱胎而来，新事物是在批判地继承旧事物中的一切积极的有生命力的因素的基础上发展起来的。这样，在新旧事物之间就存在着必然的联系。

在数学上，0这个数是解决记数和进位问题而引进的概念，由于它不能表示实在的东西，很长时间人们不把它看作是一个数。认为0是无，是对有的否定。从唯物辩证法的观点看，这种否定不是形而上学的简单否定，而是具有丰富内容的辨证否定。辨证的否定是发展的环节。0是从无到有的必经之路，是连接无和有的桥梁。0又是正数和负数之间的界限，它既否定了任何正数，也否定了任何负数，是唯一的中性数。但它又是联结正数和负数的中间环节。没有0，负数就过渡不到正数去，正数也休想发展到负数来。数学中的0是对任何定量的否定。如果没有这一否定，任何量的发展都无从谈起。这个否定不是一笔勾销，而是扬弃。因为它克服了任何定量的有限性，成为其发展的环节。在现实生活中，0作为辨证的否定，也体现出联系和发展的性质。如0度不是没有温度，而是非常确定的温度。
部编版语文八年级下册《庆祝奥林匹克运动复兴25周年》教案
2004年的雅典奥运会上，孔令辉获得冠军时忘情地亲吻胸前的国徽时，王军霞夺得金牌后激动的身披国旗绕运动场奔跑时，我们的泪水也会与领奖台上以手抚着胸前国徽高唱国歌的运动员的热泪一起落下。为了看体育比赛，我们甚至不惜守候到半夜而无怨无悔。在半夜看比赛时，我总在想：是什么让我们“为伊消得人憔悴”，为什么“总有一种力量让人泪流满面”。现在我有了答案：那是一种奥林匹克精神在激励着我们，在提升着我们。奥林匹克精神的内涵是丰富的。国际奥委会主席罗格在其就任宣言中指出：“奥林匹克的格言是更快、更高、更强。在新世纪来临的时候，或许对体育来讲需要新的格言，那就是更干净、更人性、更团结。” 奥林匹克精神让我们振奋，今天我们就来学习这篇课文《庆祝奥林匹克运动复兴25周年》。
