春季开学第一课暨新学期国旗下讲话稿
老师们、同学们，大家新年好！伴随着雄壮的义勇军进行曲，鲜艳的五星红旗再次在我们眼前冉冉升起，一个充满希望的新学期已经开始了。大家刚刚经过了一个愉快而有意义的寒假，度过了一个非常值得回味的新春佳节。回首刚刚过去的一年，全体同学勤奋好学，全体教职工严谨教学。过去的一年我们全体竹中人齐心协力、勤奋学习、扎实工作，学校获得了很好的发展，同学们取得了不错的成绩。XX年高考我校再创辉煌，大批同学被高校录取，在上学期期中、期末考试中我校成绩表现良好。全体教师的专业素养得到了很好的发展和提升，在溧阳市第九批“四类优秀教师”评选中，我校有24位老师被评为“四类优秀教师”，在学科基本功竞赛和优秀课评比中，我校有10多位老师获等级奖，同时学校也承担了10多次市级学科教研活动和校际教研活动，2次学科理事会年会活动。同时，学生的特长和能力也得到了很好的彰显，在参加江苏省第十五届作文大赛中，有35位同学获奖。在初中英语口语比赛中有3位同学分别获一等奖和三等奖。在八年级“古诗文创作”比赛中有2位同学获奖，同时有不少同学被评为省、市、校级“三好学生”、“优秀学生干部”。等等。
XX年春季期第一次国旗下讲话：爱护环境
亲爱的老师、亲爱的同学们：早上好！我是六年级（2）班的学生项XX。这次我要演讲的题目是《爱护环境》。 当你们走在路上时，看到了垃圾，是否弯下腰来捡起它？当你走在草地上时，你是否能帮它们捡起草丛中的造物？这时，很多人都会说自己做了，但真正能做到的又有几个？一次，我走在回家的路上，一个走在我面前的大哥哥手里拿着一个香蕉皮丢在地上，然后若无其事地走开了。这行为真让我人气愤。这时来了一个小女孩，她看见地上的香蕉皮就弯下腰捡起来，丢进垃圾桶理你。同学们，听了这个小故事，你愿意向谁学习呢？现在，有个别人素质低下，他们对地上的垃圾熟视无睹，把随地乱扔垃圾当成了家常便饭。可是这样做的后果是什么？地上的垃圾成堆，没有人再去理会。大地被污染，小草在哭泣，臭氧层被破坏。我们的地球妈妈给予我们这么美好的生活环境，就这么让我们破坏么？
XX-XX学年第二学期第一周国旗下讲话
老师们、同学们：大家好！ 今年是羊年，动画片“喜羊羊与灰太狼”中的小羊们成为新年问候中的一个高频词，人们通过这种独特的祝福方式表达对新年生活的愿望与向往。开学第一一个周会，作为校长，我也想借用“这部动画片”，向全体师生送上我衷心的祝愿。 首先，祝愿大家暖羊羊。上周同学们走进校园，许多同学们都精神饱满，满脸愉悦，见到教师都送上了祝福，让我们收获了温暖和爱意。爱是需要表达的，也是需要传递的。记得去年，我校中层8位领导慷慨解囊，资助我校品学兼优，但在生活中有困难的6名同学，每人XXX元。就是种下了一颗颗温暖的种子，希望他们能够开出灿烂的花朵，来完成自己的学业，实现自己的抱负，回报母校一个微笑。也是去年，期末表彰会上，同学们在台上大声喊出自己的梦想，伸开双臂拥抱老师的场景，我相信，每个人身上都流淌着热血，温暖在彼此间传递。我希望，在初三的岁月里，同学们不仅要在文化知识方面有所成长，更希望同学们学会感恩，敞开心扉多一些真实的情感流露，让我们彼此暖羊羊。这样我们的生活才充满阳光。
