    XX年3月国旗下的讲话:三月学雷锋

    为大家收集整理了《XX年3月国旗下的讲话:三月学雷锋》供大家参考,希望对大家有所帮助!!!各位老师,各位同学:大家好!阳春三月,是我们学校的学雷锋月,也是我们学习雷锋的开始月。今天,我国旗下演讲的题目是“帮助别人,快乐自己”。当你在大街道上跌倒,有人在一旁嘲笑你,却没有扶你的时候; 当你的钱包被小偷偷走,旁人看见却不敢吱声的时候; 当你一个人需要人帮助,却没有人愿意帮助你的时候。各位同学,你,会是什么心情呢?想必会酸、苦、涩。可就在这时候,有一个人伸出了自己的手,去扶你,去帮助你,你是喝令他走,并说这种精神过时了,还是心存感激地接受帮助呢?答案是很明显的。雷锋精神依旧在我们身边灼灼发亮,雷锋精神的实质就是全心全意为人民服务,我们作为一名福高人,应该尽自己绵薄之力帮助别人,展现福高学子的奉献精神。帮助别人,快乐自己。

  •  关于全国爱眼日的国旗下讲话

    关于全国爱眼日的国旗下讲话

    关于全国爱眼日的国旗下讲话尊敬的老师,亲爱的同学们:大家好!今天,国旗下讲话的主题是《爱自己,从爱护眼睛开始!》。我们都知道眼睛是心灵的窗户,爱自己,就一定要爱护好眼睛。特别是我们小学生处于人生学习的黄金期,天天学习离不开眼睛。据有关资料显示,我国有 五百万盲人,七百万双眼低视力者,单眼低视力者高达四千万人。同学们你们知道吗?一旦患了近视,戴上眼镜会给学习和生活带来很多不便。例如在参加体育活动的时候,打篮球或踢足球时,打破眼镜甚至伤及眼睛到医院做手术缝合是常有的事。形形色色的眼病不仅严重危害了人们的身心健康,也阻碍了人们生活质量的提高。一个正常人如果离开了眼睛简直无法想象怎样生活?看看我们周围,真正明亮的眼睛又有多少呢?

    国旗下讲话:做个文明的好孩子

    寄语:以下是为大家准备的关于演讲稿的文章,希望可以帮助大家。尊敬的老师,亲爱的同学:早上好!在和煦的春风里,万里焕发了生命力。我们美丽的校园里也在悄悄地发生着变化。同学们在春天里变得活跃起来,课间爱在操场上奔跑和追逐,是的,生命在于运动。瞧,我们的老师已在操场南面的墙上为你们绘制了体育健儿运动的画面;不知道你们观察过没有,在植树节里,有许多棵树悄悄地在我们的校园里安了家,正迎着阳光雨露想和同学们一起茁壮成长;路旁的花坛里,小草欣欣然张开双眼,一切显得那么美好。可有的同学在玩耍时常爱用脚去踩无辜的小草,用手去摇可怜的小树。“小朋友,我们需要休息。等到夏天,我们会给你们浓浓的绿阴。”同学们,你们听了这样的声音,你还忍心打扰他们吗?

    国旗下讲话:安全,永恒的主题

    为大家收集整理了《 国旗下讲话:安全,永恒的主题》供大家参考,希望对大家有所帮助!!!各位老师、同学们:大家早上好!今天我国旗下讲话的题目是《安全,永恒的主题》。对于每个人来说,生命都只有一次。注意安全,就是善待和珍惜生命的一种有效途径,专家认为,通过教育和预防,80%的中小学生意外伤害事故是可以避免的。在这里,我向全校同学提出如下建议:一、遵守交通规则和交通秩序。来校、回家做到文明行路,出校门也不要边讲话、打闹,边骑车,要注意过往车辆状况;不闯红灯,过马路要机警,不走机动车道,不逆行;不骑自行车带人。

  • 在全市两违工作会议上的讲话

    在全市两违工作会议上的讲话

    同志们:这次全市清理违建工作会议,是在特殊形势下召开的一次下决心、动真格、打硬仗的专题会议。今年以来,市委多次召开会议,研究部署违建清理工作,并先后组织开展了几次大规模的专项行动,有力刹住了非法占地抢建之风,遏制了“两违”的蔓延势头。在看到成效的同时,我们更要清醒地认识到,现在违建的歪风开始重新抬头,从中心市区到城乡结合部,再到周边乡村,都不同程度地存在。这不仅严重阻碍了项目落地,阻碍了城市发展,影响了社会和谐稳定,从根本上说也损害了大多数人民群众的利益。之所以出现这些现象,我认为主要有以下几个原因:一是住房需求。在房价走高的情况下,一些人心存侥幸、铤而走险,违法违规建设住房。二是利益驱使。一些人“以房生财”,或用来出租经营,私自违建、高价出售;或为牟取超额拆迁补偿费用,顶风作案。三是执法不严。部门齐抓共管格局的合力没有形成,网格化管理责任没有落实到位,“清违”工作时紧时松,致使违建者对“清违”行动持怀疑态度,等待时机“东山再起”。还有,在同一片区的违建房,有的拆了,有的没拆,导致群众认为执法就是欺负老实人,“找人、说情、送礼”就可幸免于难。

  • 在2023年招商引资推进大会上的讲话

    在2023年招商引资推进大会上的讲话

    同志们:今天我们召开招商引资推进大会,主要是深入学习贯彻上级有关会议精神,进一步解放思想、凝聚力量,抢抓黄金招商季,迅速掀起新一轮大招商、大开放热潮,以招商引资工作的新突破推动经济高质量发展,为奋力建设社会主义现代化新**贡献新的力量。刚才,**同志对当前招商引资工作作了具体部署,大家要认真抓好贯彻落实。*个单位作了很好的表态发言,希望大家互相学习借鉴。下面,就做好今后工作,讲三点意见。一、提高政治站位,把准发展大势,切实增强大抓招作的责任感、使命感、紧迫感招商引资是经济工作的重要抓手,招商引资工作抓得紧、抓得实的地方,经济发展都呈现出了持久的动力和广阔的前景。各级各部门要从战略和的全局高度深刻认识这项工作的重要性和紧迫性,切实把招商引资摆在更加突出的位置,站位再提高、压力再传导、工作再加强,迅速推动形成大抓招商的生动局面。第一,奋力追赶进位,必须以招商引资求突破。当前,我们仍然是欠发达地区,经济总量处于全国中游,与前面的标兵差距不小,后面的追兵又追得很紧,必须从扩大优质增量和提升优化存量入手,努力在追赶超越中实现高质量发展。招商引资工作既是培育新增长点、扩大优质增量的“一号引擎”,也是促进资源要素重组、提升优化存量的“关键因子”,更是推动经济高质量发展的“源头活水”。

Finish Exercise 4 on Page 15 of the textbook.A smart home is one that integrated computers into the structure of the building itself. In this way, many of the things that we now do ourselves become automatic. For example, the smart home could control the air conditioning and lights so that you would no longer have to turn switches on and off, and so that your home would be more energy-efficient. The smart home could also monitor itself to make sure that everything is working as it should, and send you warnings if there is a problem. Such smart homes could even be programmed to detect your health problems, and then give you reasonable advice as to the food you should eat or if you should see a doctor. So, in a sense, smart homes will lead us to living smarter lives.2.Create a smart function for your home, and share your creation in the next period.
