    “文化遗产日”国旗下讲话稿:中国传统文化的艺术珍品

    敬爱的老师们,亲爱的同学们,大家上午好!我是来自高二、七班的龚xx。今天我演讲的主题是“中国传统文化的艺术珍品”。不知大家闲暇时有什么爱好?我最爱画得桃红柳绿的花旦玉兰指一压唱一曲《牡丹亭》。牡丹亭属于昆曲。昆曲,又称昆剧、昆腔、昆山腔,是中国最古老的剧种之一,也是中华传统文化艺术中的珍品。十四世纪中叶,元代末期,昆曲发轫于吴语系的昆山。十五年前的5月18日,这对大多数昆曲爱好者而言是一个特殊的日子。昆曲在XX年5月18日被联合国教科文组织列为“人类口述非物质文化遗产代表作”。从昆曲开始,中国传统文化逐渐走向世界的舞台,此后共有31项文化遗产申遗成功。与昆曲属于同一文化体系的,有柳暗花明,曲径通幽的苏州园林艺术,有巧夺天工,色彩明丽的苏州刺绣,他们都是江南文化的精髓。

    国旗下的讲话:让成功在和谐校园里激励我们前行

    伴随着国旗冉冉升起,我们伟大的祖国在祥和庄重的氛围中度过了63周岁的华诞。在举国欢度国庆节的前夕,在刚刚过去的9月25日21时10分04秒,神州七号载人飞船带着翟志刚、刘伯明、景海鹏三位宇航员一飞冲天,带着中华民族克服冰雪灾害以及汶川地震的百折不挠的精神、带着成功举办奥运会、残奥会的顽强拼搏精神,骄傲地向太空宣誓:太空漫步,我们中国人来了!当五星红旗在太空、在翟志刚的手上傲然挥舞时,我们已经成功地成为世界上实现太空行走的第三个国家。身处伟大的祖国,我想每一个中国人、包括全校师生心底的那种豪迈无法用语言来形容。今天,我们度过国庆七天长假重新回到校园,我们同样要勾勒出我们自己的成功路径。1276名08级同学通过9月份的试读考查,即将陆续取得xx市xx商业学校的学籍;1193名07级同学正式进入主攻专业技能的第二学年;06级高考班45同学进入了冲刺的第三年,他们在新学期动员大会说有信心“用勇气刷新成绩”

    国旗下的讲话演讲稿:讲究卫生,预防疾病,从我做起敬爱的老师,亲爱的同学们: 大家好!今天我讲话的题目是“讲究卫生,预防疾病”。 杨柳阴阴细雨晴,残花落尽见流莺,时值四月,正是一年春好处。春天,是寻访自然 踏青远足的季节,亦是各种呼吸道传染病的高发季节。 如今,曾令人闻风丧胆的禽流感病毒降临宣城,谈“禽”色变的恐慌,再次冲击着这座古老的城市,这诚然是对宣城人民意志与身体的考验。据调查,在往年的禽流感传染病例中,死亡率高达63%,所以,抵御禽流感的最佳办法就是做好预防措施。

    国旗下的讲话:第十八届“世界水日”珍爱每一滴水

    老师们,同学们,今天——XX年3月22日是第十八届“世界水日”,3月22-28日是第二十三届“中国水周”。联合国确定的XX年“世界水日”主题是“关注水质、抓住机遇、应对挑战”,我国纪念XX年“世界水日”和开展“中国水周”活动的宣传主题为“严格水资源管理,保障可持续发展”。关注新闻的老师和同学都知道,我国的云南省正在遭受60年不遇的大旱,几个月没下雨。河塘干涸,水井干枯,600余万人饮水困难,3000万亩农田受灾。更可怕的是,据气象专家预测,云南的旱情有可能持续到5月份雨季到来之前。我们的家乡天津也是一个缺水的城市。天津自身没有水源,降水量也小,缺乏贮存水的条件,目前,天津的城市用水主要依赖滦河水。1983年竣工的引滦入津工程全长234千米,是当时中国最长的引水工程,平均每年向天津市输送 亿立方米的淡水。但是,引滦工程并没有彻底解决天津的水危机。尤其是最近几年,我国北方地区连年干旱,水质污染,水资源的可利用量日趋紧张,而用水浪费则进一步加剧了水资源的短缺。

    关于倡导低碳生活,打造绿色校园的国旗下讲话

    倡导低碳生活,打造绿色校园xxx班 xxx亲爱的老师,同学们:早上好!我是xxx班的xxx。今天,我国旗下讲话的题目是《倡导低碳生活,打造绿色校园》。现在我国正在积极倡导“低碳生活”。所谓“低碳生活”,就是指生活中所耗用的能量要尽力减少,从而减低二氧化碳的排放量。我们应该积极提倡并去实践低碳生活,要注意4个节约:节电、节水、节油、节气,从这些点滴做起。也许有同学会问,节能减排,应该是政府和企业关注的事,似乎和我们学生无关。那你就错了,社会大家庭中的每一个人,都与这件事密切相关!大家知道吗?如果人人养成随手关灯的好习惯,那么全国每年可节电约20亿千瓦时,减排二氧化碳188万吨。如果每年全国有10%的纸巾使用改为手帕代替,那就可减少纸张消耗约万吨,节能2万吨的标准煤。现实生活中,我们每节约一滴水,一度电,一张纸,一粒粮食,都是对环保的贡献;生活垃圾的合理处理,废旧电池的合理回收,对校园及其他公共绿地的爱护,对身边有损环保现象的劝阻……所有这些,都是我们应尽的社会责任。

    读书节国旗下讲话:让读书成为最美好的生命举止

    尊敬的老师、同学们:早上好!今天,我发言的题目是《让读书成为最美好的生命举止》春暖花开的四月,我们将迎来xx三中的第六届读书文化节,每年的这个季节,我们的校园繁花盛开书香飘逸,鲜花装点校道,书香涵养性灵。让我们一同走进翰墨书香的世界,不为分数,不为排名,只因为,阅读,确确实实是一项最美好的生命举止。古人说,书中自有黄金屋,书中自有颜如玉。不可否认,书籍能让我们增长知识和才干,能给我们的未来打下坚实的基础,能给我们带来许许多多可以触摸、可以预期的利益。然而,在这个花香满园的四月,我更愿意提倡同学们去读那种能让人心灵沉静,能促人思考,能给人智慧的书。宋代黄山谷说:一日不读书,尘生其中;两日不读书,言语乏味;三日不读书,面目可憎。就我的理解,这里所说的如果不读就会让人面目可憎的书,不会是那些能产生立竿见影效果的工具书或各类方法大全,也不会是我们许多同学曾经心爱的《知音漫客》或者各类练习册、试题集,而是像曹雪芹的《红楼梦》、罗曼罗兰的《名人传》、培根的《培根论说文集》、摩罗的《悲悯情怀》这样的书

    敬爱的老师们、亲爱的同学们:清晨,我们相聚在此,能够站在国旗下讲话,我感到很荣幸,谢谢老师给了我这样一个宝贵的机会,今天,我要演讲的题目是《让我们迎接期末考试的到来》!有这样一首歌大家听过吗:“阳光总在风雨后,乌云上有晴空,珍惜所有的感动,每一份希望在你手中。”这首歌的名字大家应该很熟悉,叫做《阳光总在风雨后》。生活就是如此,不经历风雨,怎么能见到彩虹?那么我们不经历期末考试,怎能知道我们学习的效果?怎能知道我们的成绩是什么?期末考试就快临近了,我们都进入了紧张的备考阶段,同学们,你们做好准备了吗?在这里,我想给大家提点建议,有不足之处,请大家批评指正。第一,与时间赛跑。时间就是生命,时间就是一切,也许一分钟的时候不能给你带来一分的成绩,但是一分钟的时间,绝对可以给你带来一点一滴的进步。在历史的长河中,时间是最公正的,但也是最短暂的,只有争分夺秒去努力,只有与时间赛跑,我们的成绩才会有更多的进步,期末考试才会变得轻松自在。

    Everybody wants to get wealth.In today’s material world,making money or becoming wealthy symbolizes a person’s success and capability. Many people just make every effort, pay any price to attain greater wealth. With money,they can buy nice, large apartments in nice neighborhood. With money they can own luxurious cars. Wealth seems to bring all happiness in life.But is wealth the only road to happiness? Not really. There are many things in the world, which are beyond the means of money, such as friendship, love, health and knowledge. People are so preoccupied with struggling for money that they have no time or would not take the time to form or maintain friendship. What happiness can they feel living as lonely miserable creatures without love or friends in the world even if they accumulate tremendous wealth?In my opinion, people can’t do anything without money, but money is not everything. What money will bring you depends on your personal belief and goal in life. If you are kind enough to help others, especially the poor, money is a good thing to you. With it, you can do much more for the benefit of people and your country, and it will add to your own happiness. If you want money just for your own needs, you’ll never be satisfied or happy. In a word,you should have money spent for more people. Only then can money be the source of your happiness.Step 8 Homework4 students in a group, one acts Roderick, one Oliver, one servant and the fourth one acts Henry Adams, then listen to the tape, pay more attention to the difference between American English and British English in pronunciation, stress, tone.

I especially liked an area of the museum called Light Games.it was really cool. They had a hall of mirrors where I could see myself reflected thousands of times!? Bill: A hall of mirrors can be a lot of fun. What else did they have?? Judy: Well, they had an experiment where we looked at a blue screen for a while, and then suddenly we could see tiny bright lights moving around on it. You'll never guess what those bright lights were!? Bill: Come on, tell me!? Judy: They were our own blood cells. For some reason, our eyes play tricks on us when we look at a blue screen, and we can see our own blood cells moving around like little lights! But there was another thing I liked better. I stood in front of a white light, and it cast different shadows of me in every color of the rainbow!? Bill: Oh, I wish I had been there. Tell me more!? Judy: Well, they had another area for sound. They had a giant piano keyboard that you could use your feet to play. But then, instead of playing the sounds of a piano, it played the voices of classical singers! Then they had a giant dish, and when you spoke into it, it reflected the sound back and made it louder. You could use it to speak in a whisper to someone 17 meters away.? Bill: It all sounds so cool.
