☆ 两种表面对立的事物或现象
谈到A和B, 没有人会感到陌生, 因为在电视、报纸、大学的讲堂和日常生活的很多角落，都有越来越多关于它们的议论。
给A和B精确而恒定的定义并非易事，因为它们的概念涉及了科学、人性、思想、经济、社会以及自然等广阔领域。
众所周知A和B是一对矛盾的事物，但对于AB之间的微妙联系以及A和B共同影响世界的原理，人们却知之甚少。
从表层和局部的视角来看，A和B是简单而纯粹的对立关系，
（4选1）
(1) 似乎A的存在就意味着B的消亡。
(2) 似乎A的开始就意味着B的终止。
(3) 似乎A的进步就意味着B的倒退。
(4) 似乎A和B互为发展的障碍和制约的条件。
但通过深层和全面的分析，我们发现AB之间有着动态而复杂的联系。其一，A与B的矛盾格局并非恒定不变。虽然大部分时候，A与B间有着直接而尖锐的对立，但所有对立总有归于缓和的一刻。其二，AB间隐含着一定的因果关系。在一般情况下，A与B总是相互抑制，但如果没有A的存在，那B也就失去了常规的意义。其三，从本质层面，用哲学的眼光来看，A与B不过是同类社会运动的两个阶段。在足够的条件下，A与B可以相互转化。
总之，我们应理性地认识A与B的关系，在充分掌握A与B对立统一规律的基础上，科学地引导和利用AB的矛盾运动，以便为社会的进步创造更优的模式、倾注更强的动力。
Two apparently opposite objects or phenomena.
A and B are nothing strange for us, because increasingly more argumentations about them can be found in TV programs, newspapers, university classes and many aspects of our everyday life.
Since their concepts cover vast fields, such as science, humanity, ideology, economy, society and nature, A and B are never easy to be defined precisely and fixedly.
While A and B are widely known as contradictory to each other, we know little about the subtle relationship between A and B, as well as the principle that A and B influent the world jointly.
From the superficial and partial point of view, A and B are simply and purely opposite. It seems that:
(1) the existence of A means the extinction of B;
(2) the beginning of A signifies the ending of B;
(3) the progress of A means the retrogression of B
(4) A and B are each other’s barrier and restraint in their development.
However, when A and B are analyzed more comprehensively, there is a dynamic but complicated relation between A and B. for one thing, the contradiction between A and B is not constant. For another, it implies certain causality between A and B. Generally A and B restrict each other. But if without A, B also loses its regular significance. Still yet, from the perspective of philosophy and their essence, A and B are merely two stages of the same social activities. When conditions favorable, A and B can mutually transform.
In general, we should reasonably recognize the relation between A and B. On the basis of fully mastering the unity and the contradictory we can lead and utilize movement of A and B scientifically, so that we can create a better mode and introduce striper impetus for social improvement /development.
