关于水的作文400字左右说明文【二】
水文化在中国传承了五千年，水象征着圣洁，象征着无私，象征着真诚朴素……中国历代依赖都缺水，不能前进，国家缺少水，不能强大。“君子之交淡如水，小人之交蝇如利。”试想一下，中国人人身上都不缺水，那是一番怎样的景象，地球上的每个人都是水一般的透彻那会如何？可以大胆预言种族之间不会歧视，能看到的只是他们相互交流，尊重。国家之间再也不会有领土之争，他们之间只有互惠互利，携手同进，地球上不会再有战争，即使是打架也不会出现，能看到的只是一群在天上自由自在飞翔的.白鸽。
梦想与现实总是相反的，而今的人缺水，社会缺水，国家，甚至地球缺水。小悦悦事件揭露了人性的丑陋；叙利亚所经历的劫难，也是统治者为了己方的利益，不惜挑起无端战火，让千千万万的人民葬身战火之中，让无数家庭破碎。人是多么可怕的，为了利益可以抛弃人的光辉，可以侵略别国的领土，可以顷刻间让原本鲜活的生命变成冰冷的尸体。
作为一名中国人我十分愤懑，不仅仅因为我所处的社会缺少水的精神，更因为中国在面对日本等国家侵犯我们国家领土时，中国不能明确立场，实施强势的对外政策，国人不能立时紧张起来，为保卫家园同心协力，互相帮助，为维护主权而奋斗，更为了自己民族而努力，而不是若无其事的对待。
老子曾说过：“上善若水，水利万物而不争，处众人之所恶，故几于道。居善地，心善渊，与善仁，言善信，政善治事善能，动善时。夫唯不争，故无尤。”无论身处何地。遇到如何境况，我们都应像水奉献，为祖国绽放出最美的花朵。
