交警关于小学生交通安全的演讲稿

全文共 1229 字

+ 加入清单

各位领导、在座的各位小朋友:

大家好!在开始我的演讲之前,我想先问大家一个问题,在您的印象中,横向排列的红绿灯是红灯在左边还是绿灯在左边纵向排列的红绿灯是红灯在上面还是绿灯在上面我想在座的大多数人都不能马上给我一个明确的答案。这也许正从一个小小的侧面反映了我们对交通法规的重视吧。然而今天我们相聚在一起,举行本次比赛,我想在座的各位领导和老师的目的就在于加大交通安全的宣传力度、提高我们的交通安全意识,从而使我们的交通管理工作进行地更有效更彻底。而我认为这一切的最根本保证就是您、以及大家对交通法规的自觉遵守。随着时代的进步,随着科技的发展,交通在我们的日常生活中发挥着越来越重要的作用,随之而来的便是交通问题的日趋严重和交通管理手段及方式的日新月异的变化,在如此快节奏的背景下,可以说从你到我、从司机到行人,每一个人都穿梭在红绿灯的交替变换中。红绿灯似乎成了现代交通的代名词。然而,也就是在这红绿灯下,多少克尽职守者倾洒汗水、多少粗心大意者飞溅鲜血;多少人为了他人的幸福实现了自我价值、多少人为了赶一点时间自毁了前程;多少热血青年在风吹雨打中奉献青春、多少亡命之徒在推杯换盏后命丧黄泉人们就是这样在红绿灯下演绎着一个个属于自己的角色,演奏出一曲曲属于自己的生命交响!

是啊!人的生命是最宝贵的,只有有了生命才能创造财富,才能使世界变得更美好。只有同学们的欢声笑语、活泼身影,才能使我们的校园充满阳光,充满生机。但是人的生命又是非常脆弱的,如果我们不重视安全,视安全隐患而不顾,对安全问题措施不及,防范不严,责任心不强,把生命当儿戏,那么造成的后果不堪设想。交通事故猛如虎狼,我们身边随时都潜伏着

张牙舞爪的杀手随时都威胁着你的生命安全。一件件,一桩桩血腥的报道,令人胆战心惊,一幕幕惨剧目不忍睹。只因为忽视了安全问题,一个个生命如鲜花在瞬间凋零,后果带给社会、家庭、亲人只是悲痛欲绝的伤心,沉重的打击,血的教训。到那时,这一切都为时已晚,我们失去的已经太多太多,对生命的关爱,不能成为美丽的词藻,难道只有失去之后才能醒悟。由于安全意识的淡薄,由于责任心的冷漠,玩忽职守而造成,难道我们不该反思,不该惩罚和加罪。而我们今后还能做些什么更令人深思。

人的生命也是脆弱的,生命如果发生什么意外,会留下永远的伤痕;健全身体一旦失去,将永远无法挽回。因此,我们应该好好珍惜我们生命中的每一天,在生活中注意安全,使自己平安健康地成长。让我们每一个人永远平安、快乐!让我们时刻牢记:珍爱生命,安全第一!

所以,我们要学会生存,珍爱生命,让我们在灿烂的阳光下沐浴一方平安,健康成长,愉快生活。人无远虑,必有近忧。面对中国2亿少年儿童,安全第一,预防为主不仅仅是社会对您或其他人的

要求,更是我们这一代人的要求,我们应该早日把这种观念扎根心中,才是刻不容缓。让我们把平安的种子撒播进自己的心田。当它发芽开花、长成参天大树,我们必将收获更多的祥和、幸福和安宁。让生命的一泓清泉,永流不息。

It will be all right," says the fairy. "Go get a pumpkin, six mice and a rat." Cinderella quickly finds them. "What will you do?" Cinderella asks. The fairy waves her wand over the pumpkin.

篇6:10TipsforSuccessfulPublicSpeaking成功演讲十秘诀

全文共 1757 字

+ 加入清单

Know the room. Be familiar with the place in which you will speak. Arrive early, walk around the speaking area and practise using the microphone and any visual aids. Know the audience. Greet some of the audience as they arrive. It’s easier to speak to a group of friends than to a group of strangers. Know your material. If you’re not familiar with your material or are uncomfortable with it, your nervousness will increase. Practise your speech and revise it if necessary. Relax. Ease tension by doing exercises. Visualize yourself giving your speech. Imagine yourself speaking, your voice loud, clear, and assured. When you visualize yourself as successful, you will be successful. Realize that people want you to succeed. Audiences want you to be interesting, stimulating, informative, and entertaining. They don’t want you to fail. Don’t apologize. If you mention your nervousness or apologize for any problems you think you have with your speech, you may be calling the audience’s attention to something they hadn’t noticed. Keep silent. Concentrate on the message — not the medium. Focus your attention away from your own anxieties, and outwardly toward your message and your audience. Your nervousness will dissipate. Turn nervousness into positive energy. Harness your nervous energy and transform it into vitality and enthusiasm. Gain experience. Experience builds confidence, which is the key to effective speaking. A Toastmasters club can provide the experience you need. 熟悉场地。争取熟悉你要在那里发表演讲的环境。提早到达并巡视讲台,练习使用麦克风和其他辅助视觉设施。 熟悉听众。在听众进入会场时向他们致意。向一群朋友演讲总比对一群陌生人演讲来得容易些。 熟悉你的讲稿。如果你不熟悉你的稿子或者对它不满意,你的紧张感就会增强。练习一下你的演讲稿,并且做必要的修改。

放松自己。做些准备活动松弛紧张的神经。 设想你自己演讲时的情景。想象你自己在侃侃而谈,声音洪亮、吐字清晰、充满自信。倘能设想自己成功,你就一定会成功。

要意识到在场的人们希望你成功。听众希望你的讲话趣味昂然、催人向上、旁征博引且风趣

Carrying Faggots to Put Out a Fire

In the last years of the Warring States period, the State of Qin attacked the State of Wei on a large scale repeatedly and occupied large areas of land, for the State of Wei was too weak to defend itself. In 273 B.B., the qin army launched another attack upon the State of Wei with a momentum more vigorous than ever. The king of the State of Wei summoned his officials,and asked with a worried look if anyone could propose a way to defeat the Qin army. After years of chaos caused by the wars,the officials trembled when fighting was mentioned, and no one dared to speak ofresistance. At the critical moment when a large enemy force was bearing down upon the border, most of the offinials persuaded the king to sue for peace, at the cost of giving away to the State of Qin the large area of land north of the Huanghe River and south of the Taihang Mountain. However Su Dai, a counsellor, did not agree. He hurried up to the king and said:"Your Majesty, they dont think about the interests of the country at all.It is just because they are cowardly and afraid of death that they ask you to sue for peace by betraying the country. Of course you can temperarily satisfy the ambition of the king of the State of Qin is insatiably greedy. It will never stop assaulting us until our land is totally given away."Once there was a man whose house was on fire. People told him to put out the fire with water, but he would not listen. Instead, he carried a faggot to put out the fire, only to make the fire fiercer. That was because he didnt know that,instead of putting out the fire, faggots could only make it burning more vigorously. Isnt it equivalent to carrying faggots to put out a fire if you agree to sue for peace at the cost of the land of the State of Wei?"Though Su Dais argument was very convincing, the king accepted the suggestion of those officials and gave away to the State of Qin a large area of the land of the State of Wei. For the king of the State of Wei was cowardly and only cared for peace at the moment.As might be expected,the Qin army assaulted the State of Wei on a large scale in 225 B.C.,surrounding the capital city Daliang and flooding it by digging open the dykes of the Huanghe River.The State of Wei was finally destroyed by the State of Qin.This story appears in the Historical Records Written by Sima Qian.The set phrase"carrying faggots to put out a fire"is used to mean adopting a wrong method to save a situation and ending up by making it worse.

战国末期,秦国向魏国接连发动大规模的进攻,魏国无力抵抗,大片土地都被秦军占领了。到公元前273年,秦国又一次向魏国出兵,势头空前猛烈。

魏王把大臣们召来,愁眉苦脸地问大家有没有使秦国退兵的办法。大臣们由于经过多年的战乱,提起打仗就吓得哆嗦,谁也不敢谈“抵抗”二字。在这大兵压境的危急时刻,多数大臣都劝魏王,用黄河以北和太行山以南的大片土地为代价,向秦王求和。

谋士苏代听了这些话,很不以为然,忙上前对魏王说:“大王,他们是因为自己胆小怕死,才让您去卖国求和,根本不为国家着想。您想,把大片土地割让给秦国虽然暂时满足了秦王的野心,但秦国的欲望是无止境的,只要魏国的土地没割完,秦军就不会停止进攻我们。”

说到这里,苏代讲了一个故事:从前有一个人,他的房子起火了,别人劝他快用水去浇灭大火,但他不听,偏抱起一捆柴草去救火,是因为他不懂得柴草不但不能灭火反而能助长火势的道理。大王若同意拿着魏国土地去求和,不就等于抱着柴草救火吗?”

尽管苏代讲得头头是道,但是胆小的魏王只顾眼前的太平,还是依大臣们的意见把魏国大片土地割让给秦国。到公元225年,果然秦军又向魏国大举进攻,包围了国都大梁,掘开黄河大堤让洪水淹没了大梁城,魏国终于被秦国灭掉了。

故事出自《史记魏世家》。成语“抱薪救火”比喻用错误的方法去消灭祸害,结果反而使祸害扩大。

篇15:水污染环境的作文

全文共 1049 字

+ 加入清单

现如今,我国对于水资源保护力度不断加大,出台了一系列的法律法规。但如何治理水污染却成了令人头疼的难题。治理水污染必须要先了解造成水污染几大“始作俑者”。

产业结构不合理,增长方式粗放是中国经济长期未能根治的痼疾,其重要表征就是重化工业尤其是资源消耗工业增长较快。问题的关键在于,由于受水资源、航运等产业布局因素的影响,重化工业沿江或沿河布置已经成为一种范式。据统计,全国两万一千多家石化企业中,位于长江、黄河沿岸的石化企业达一万三千多家。至于像小造纸、小皮革等项目在水环境敏感地区大起炉灶的现象更是比比皆是。如此产业布局的最严重后果就是大量污水在可能未经处理的情况下倾注到大江小河。据国家环保总局的调查统计,目前我国工业污水排放量每年达到300多亿吨,尤其是七大水系所承载的工业污水排放与日俱增。

来自于农业方面的面源污染超过工业污染已经成为我国水污染的一个重要特征。研究表明,农村面源污染在各类环境污染中的比重占到30%-60%,并成为水污染的重中之重,其中污水中COD(含氧量)排放已超过城市和工业源的排放总量。一方面,过量使用化肥造成的污染十分惊人。如化肥施于土壤中,只有小部分被作物吸收,大部分则在雨水的作用下或渗透到地下污染地下水,或随地表径流进入河流、稻田、池塘。由于化肥会造成水域富营养化或饮用水源硝酸盐含量超标,因此已经危害水质的“第一隐形杀手”.

农业污染可以对水资源形成伤害的另一大力量来源于畜禽和水产养殖业污染。有调查数据显示:养殖一头牛产生并排放的废水超过22个人生活产生的废水,养殖一头猪产生的污水相当于7个人生活产生的废水;北京近郊禽畜养殖场排放的有机物污染,相当于全市工农业生产污水和生活废水中所含的有机污染物的2-3倍。

就在农业污染超过工业污染的同时,另一大污染源---生活污水又从城乡的各个角落冲出并有愈演愈烈之势。据了解,中国一年洗衣污水量就将近22亿吨,相当于34个十三陵水库,76个昆明湖。仅北京市和上海市2006年生活污水分别就达到9亿和11亿吨。全国大小城市的生活污水的排放量已经超过了工业污水的排放量。

问题的关键在于,目前我国仍有61%的城市没有污水处理厂。在污水处理设施得以修建的城市,能正常运行的也只有50%;还有的由于污水收集管网的原因,污水处理厂处理量不足设计处理能力的20%.而在广袤的农村,生活污水处理设施基本为零。正因为污水处理率的低下,中水回用水平低,大量污染负荷就如泄闸之洪汹涌般进入河流与湖泊,中国水体环境质量由此被一步步逼向危险的边缘。

Sometimes the cat is really very boring, it will eat the wheat to attack the sparrow, saw the cat still like that stole the fish to go cautiously without any noise and small sparrow sparrow side, not the danger around it, then, all of a sudden forward toward a cat, a small sparrow is caught, in short, cat every time is 100% in the catch".

敬爱的老师、同学们:

大家好!今天,我演讲的题目是:《文明礼仪》。礼仪是无处不在的,它可以表现出一个人的道德修养,也可以增进人与人之间的友谊。大家都知道,我们中国是人类历史上四大文明古国之一,是一个历史悠久的礼仪之邦。中华民族五千年的发展历程,代代传承了许许多多的传统和美德。从孔融让梨到张良拜师,从周总理为中华之崛起而读书到做好事不留名的雷锋叔叔,他们都是中华民族传统美德的具体体现,他们为我们树立了榜样,是我们每一位小学生应该学习的楷模!

作为一名新世纪的小学生,作为祖国的花朵、世界的未来,我们必须做一名文明的小学生!但是,如何才能做一名文明的小学生呢?我们首先要着装得体,符合学生身份,体现出新世纪学生篷勃向上的风采,因为仪表、仪容、仪态可以让人一看便知道你的修养;遇到老师、同学,主动问好;上下楼梯,人多拥挤,注意谦让;讲究卫生,不乱扔果皮,见到纸屑随时捡起;爱护公物,不乱写乱划;在与同学的交往中,能和睦相处,共同学习。做到得理让人,失理道歉,相互尊重,相互信任;家里来了客人,热情、大方、有礼貌地招待;在外面,遵守交通法规,不乱扔果皮纸屑,保护环境卫生;尊老爱幼,帮助别人,做到处处为别人着想。

让我们一起努力,做一名穿戴整齐、懂礼貌、不乱扔垃圾的小学生。我的演讲结束了,谢谢大家。

Last week, I received a post card from my friend, which was from Thailand,

I felt so excited, because I always wanted to travel abroad. So I was so eager

to talk to my friend. She showed me the sceneries. I found different sceneries

in different cities. For the first time, I saw the outside world so closely. I

want to explore the world and know more about this planet. I realized the

importance of learning English. If I master more words, then I can communicate

with the local people and learn about their culture. From now on, I must study

hard. When I have the chance to travel abroad, I can have a trip.
