XX学年期末考试国旗下讲话：勤于积累，善于反思
L：李xx：xxL：各位老师，各位同学，上午好，我是88班的李xx。Q：我是88班的xx。今天我们演讲的主题是：“勤于积累，善于反思。”L：哇，xx，你又在暗推了！Q：我是在积累英语单词啊！粗略估计，我这一年半来积累的单词，连起来可绕地球半圈。学习，可不是完全拼脑力的工作，它可是一次长途的跋涉。我曾看到过一个数据：假设你每天都比别人多积累百分之0.01，一年后你的成果就是1.01的365次方约为37.7，远远大于那些还在原地踏步的“1”。而如果你每天都退步一点点，则一年之后你则会被远远抛到后面，一事无成。正所谓“不积跬步，无以至千里；不积小流，无以成江海”啊。L：你这样一说，我也觉得积累是学习中重要的一大部分。水滴石穿，靠的是坚持不懈地努力，它的成功就是日积月累换来的。文科需要积累，对于语文，我们可以日常积累好词好句，让诗歌、作文焕然出彩；对于英语，我们可以积累单词扩大词汇量。中国最有名的英语辅导机构——新东方的优秀学员的基本功练习便是将《牛津英语大字典》反复背诵六七遍，可见词汇的积累是有多么重要；对于社会，我们则可以积累历史知识。
XX--2018学年第一学期第八周国旗下讲话稿：秋意寒 勤锻炼
XX--2018学年第一学期第八周国旗下讲话稿：秋意寒勤锻炼尊敬的老师们、亲爱的同学们：大家好！今天，我国旗下讲话的题目是《秋意寒勤锻炼》。秋季的到来，给南方的天气增加了几分寒意，这个季节，没有了夏日的骄阳，正是锻炼身体的好时机。参加秋季体育活动，不仅能够锻炼身体增强体质，而且还能提高身体的抗寒能力和增强抵抗各种疾病的能力。秋季体育锻炼，由于肌肉不断收缩，呼吸加快，新陈代谢旺盛，身体产生的热量增加。同时还增强了大脑皮层的兴奋性，使体温调节中枢灵敏、准确地调节体温，提高人们的御寒能力。在锻炼中接受阳光的照射能够促进身体对钙、磷的吸收作用，有助于骨骼的生长发育。尤其对正在长身体的同学们来说，多参加户外锻炼更为重要。
XX-XX第二学期第六周国旗下讲话稿：珍惜粮食，做勤勉节俭的xx学子
尊敬的老师、领导，亲爱的同学们：大家早上好!今天我发言的题目是“珍惜粮食，做勤勉节俭的xx学子”。关于这个题目，我的发言有三点。第一，珍惜粮食，从我做起。“谁知盘中餐，粒粒皆辛苦”告诉了我们粮食来之不易的道理。学校领导很早就倡导全校师生开展“光盘行动”：盘里不剩菜，碗里不剩米。无论对于老师还是学生，这个标准都不能打任何折扣。可是现在，我们仍然可以看到有同学浪费食物的现象，吃不完的米饭随意倒掉，而且很“大方”、不犹豫。试想，我们学校近300名师生就餐，每人每顿少浪费一粒米，这数额积累下来，至少可以让一个饱受饥饿之苦的人解决温饱问题，这样下来，又可以节约资源求得学校更好的发展，何乐而不为呢？都说温饱不忘饥寒，增产不忘节约。我们处在衣食无忧的好时代，学校也处在稳步发展的关键时期，我们要从自身做起，珍惜粮食，杜绝浪费。
