2．人工智能、信息及其对意识论的深化现代科学的发展，特别是以信息论、控制论、电子计算机科学和脑科学相结合为理论基础的人工智能技术的发展，进一步证明了辩证唯物主义关于物质和意识的相互关系的原理，也给这种现代唯物主义提出了需要深入探索和解释的许多哲学问题。在这些问题之中，人工智能和信息尤为重要。人工智能是相对于人的自然智能而言的。所谓自然智能，是指人所特有的自觉的意识能力，特别是抽象思维能力。由于这种能力是人的一种天赋，所以将其称为人的自然智能。所谓人工智能，则指凭借电子计算机所实现的对人的某些智能的模拟，通过这种思维模拟，使人的某些智能得以再现和放大。自从电子计算机在20世纪中期问世以来，其作用越来越广泛，模拟功能越来越强，更新换代越来越快，对生产和社会生活的影响也越来越大。自50年代中期开始，人工智能便以计算机作为主要的支持手段，逐渐发展成为一门新兴的科学技术。

XX小学暑假安全教育国旗下讲话稿各位老师，亲爱的同学们，大家好!紧张的一个学期接近尾声了，我们又迎来了盼望已久的暑假。怎样过好这个长假呢?我们有太多的设想与计划，我们有太多的欣喜与希望。可是，这一切，都是建立在安全的基础上的。因此在假期中，我们每一个同学都必须提高安全意识，学会自我保护。今天，我在这里要再三重申和提醒大家：安全是生命之水，文明是幸福之源!假期一定注意安全，希望大家不仅要记在脑子里，更要落实到行动上。希望同学们从以下几个方面做起：1、防溺水事故：溺水事故是夏季在安全方面存在的最大隐患，因为每年在这个季节里我们的周围都会发生许许多多令人惨痛的事故和教训，并且这些教训往往是以生命的失去而作为代价的;而对于一个家庭来讲，孩子生命的失去往往就意味着一个幸福家庭的破裂甚至毁灭。今天，我再次重申，绝对禁止到危险水域玩水。由于天气炎热，这个问题最容易出现，请同学们务必引起注意，坚决做到不在水库或深水区玩耍;不准与同学结伴到无安全设施、不熟悉，无救护人员的水域游泳。游泳时一定要有家长的陪同。
