三分钟演讲稿范文 篇1

　　亲爱的老师，同学们：

　　大家好！我是xx班的。今天我演讲的题目是《文明礼仪从我做起》。

　　初秋的空气总是让人心旷神怡，走在我们美丽的校园里，我总是能感受到文明礼仪的潮水向我涌来。但校园里也有一些不和谐的行为。今天我就要和大家说一说中学生的习惯和礼仪。

　　很多同学心里都有这样一个问题，什么是礼仪？简单的说，礼仪就是律己敬人的一种习惯，礼仪也是教养素质的一种体现，它关系着个人的修养，关系着集体的荣誉。中华民族素有“礼仪之邦”的美称，我们每一个炎黄子孙都有发扬、传承这种美德的责任和义务。

　　落实到行动中我们应该怎么做呢？从小事做起，搞好个人卫生。服饰发饰整洁是对他人的尊重。作为一个学生，我们应该穿着校服，仪表整洁大方，这是我们对老师直观上的尊重。我们对他人的尊重与否，很大程度上也反应在我们的言行之中。那么我们首先就要做到语言文明，说文明的普通话，不能说脏话、骂人，这样既降低了我们的个人素质，也为我们的班级、学校抹黑。

　　说了这么多，目的只有一个，就是为了让我们的校园更美好。行动起来吧！用我们的双眼，去观察我们身边的人和事；用我们的双手，去美化我们的校园；用我们的心灵，去体会文明礼仪的美。让我们用自己的努力，共筑美好校园！
