食药局局长在机构改革人员合并交接会上的发言稿怎么写
老师、同学们,大家好。
古人云:人以铜为镜,可以正衣冠;以史为镜,可以知兴替;以人为镜,可以明得失。
那么我今天要介绍的这本书就是《中国通史》。
中华名族是一个有着五千年悠久历史、灿烂文明的民族。
送尧舜让位到秦皇汉武,从贞观之治到康熙盛世,从鸦片战争到中华民国成立……中国人勾勒出了一幅惊天动地、波澜壮阔的历史画卷 在这本书中,我了解了许多历史人物和历史故事。
比如昭君出塞:公元前33年,匈奴呼韩邪单于向汉元帝提出和亲,共保边塞安宁。
汉元帝决定挑个宫女。
但宫女们听到是匈奴,都不愿意去,只有王昭君报了名。
她嫁到异邦外族,过着艰苦的游牧生活,但王昭君并没有为此而痛苦不堪,反而与匈奴们生活地很好,还把中原文化传给匈奴,就这样,边塞的烽烟熄灭了50年,对胡汉两族人民和睦亲善与团结做出了巨大贡献,因此,她得到历史的好评。
王昭君的故事,成为我国历史上流传不衰的民族团结的佳话。
读完此书,我受益匪浅。
在浩如烟海的历史事件中,虽多与革命战争密切相关,但是影响人类历史进程的事件并不仅仅是帝王的丰功伟业和沙场上的刀光血影,有时候一件工具的发明,一种文化的出现,一次思想的进步都对历史发展产生了不可估量的影响。
同学们,一个民族如果不面对自己的历史,那么将是一个没有希望的民族。
任何一个国家想在文明发展轨道中不被抛离出去,那么就得注重用自己的历史来教育和鼓舞他的人民。
我相信这本《中国通史》就是一本很好的教材。
它是一面镜子,更是一部五花八门的大百科全书。
这本书是以时间顺序、故事的形式来叙述的,脉络清晰,系统严密。
生动的再现了一个个历史事件。
使我阅读此书时如同身临其境,既能从中学到历史知识,又能得到文学陶冶。
阅读史书,使人明智,相信《中国通史》是一份丰盛的精神食粮,值得每位同学细细品读。
谢谢。

谁能帮我写一篇关于 空气污染的原因 的演讲稿
范文一: 同学们,你见过
你见过的是街道两公园里的树调、乏味、黑不溜秋。
你见到水吗
不,你见过的是人工湖的水,浑浊、发臭、游人洗过脚的。
你见过鸟吗
不,那是笼中之鸟,呆呆的、只会要吃的。
近年来,随着经济的发展、社会的进步,我国的环境也随之变化,大自然受到严重的破坏,如果我们还不行动起来,保护环境 ,那么在未来的某一天,我们顶会濒临动植物灭绝的死亡线上。
由于我国人口素质还不够高,对生态系统缺乏认识、不了解自然规律,近年来,我国的自然环境和生态平衡已经遭到严重的破坏。
比如为取暖、做饭、盖房子大量破坏森林,进而造成水土流失、河道淤塞、洪水泛滥,由于城市无力供应干净能源,直接烧煤、烧柴造成空气污染,工厂用煤发电、没有对二氧化硫进行回收,造成空气中弥漫一氧化碳、二氧化硫粉末,出现酸雨损坏庄稼和建筑物的现象,由于城市垃圾、工厂废水来不及处理直接放入河道,使空气、水中及陆地上的生物受害造成生态不平衡,影响气候、影响人类健康生活条件,虽说我们国家地大物博,可是人均占有量占世界前列,这就要求我们对环境要做出适当的保护,我们即将跨入21世纪的大门 ,担当起主人的重任,我们能眼见着环境污染被破坏、而等闲视之吗
不,决不能,这就要求我们必须对环境做出适当的保护。
我们可以从身边一点一滴的小事做起,比如多植树造林,这就可以从根本上防止水土流失,爱护周围一草一木,不捕猎小动物等。
但这些光凭我们的努力还不够,还要号召我们身边的每一个人为保护环境而做出贡献。
先辈陆蠡说:“绿色是多么宝贵啊
它是生命、是希望、是安慰、是快乐。
”徐霞客也曾说 ,遍及高山大川,迎风沐雨,为的是“多识鸟兽虫鱼之名”。
前辈先哲的体验,都告诉我们大自然环境不仅能陶冶人的情操,净化和抚慰人的心灵,而且有助于知识的积累和事业的成功。
朋友,当你受到“白天寂寞”和“黑夜孤独”煎熬的时候,当你陷入挫折和失意的时候,当你烦恼至及痛不欲生的时候,那么,你就走向大自然吧
那个时候你就会真正知道保护自然环境是何等重要。
拥抱蓝天绿水,吻一吻泥土的芳香,在静静的山林中坐一坐,在绿色的草丛中坐一坐,顺手摘下一粒果子放在嘴里嚼一嚼,看看地上的蚂蚁不知疲倦的忙碌,都能使心绪渐渐平和,得到抚慰。
你就会在大自然的真善美中,认识到你有你年轻的生命,你拥有一段生命的里程,激发你以丰富的知识和坚强的毅力去开拓一个美好的世界。
范文二:(天天都是环境日) 世界环境日世界环境日尊敬的各位领导,敬爱的老师,亲爱的同学们: 早上好
我今天演讲的题目是《天天都是环境日》。
21世纪可谓挑战与机遇并同在,希望与困难共存。
它在给我们带来许多美好憧憬的同时,也给我们带来了许多难题,其中首要的就是环境问题。
环境与我们的生活极为密切,与我们的生存息息相关。
很久以来,我们赖以生存的环境就引起了许多有识之士的极大关注。
1972年6月5日,人类环境会议在斯德哥尔摩开幕,会上通过了著名的《人类环境宣言》。
同年10月,第27届联合国大会通过决议,将以后每年的6月5日定为世界环境日。
今年的环境日已过去两天了,但人们对环境的思考和保护永远不会停止,在我们的生命历程里,应该天天都是环境日。
伟大的无产阶级革命导师恩格斯说过:我们连同我们的血、肉、头脑一起都属于自然界,存在于自然界。
自然界作为一种客观存在,它为人类提供了各种物质和能量,是人类存…… ....你给的分好少哦,哇哇。

《时代新人从小做起 》演讲稿400字
中国了不起,中国人更了不起,要做个了不起的中国人。
我们作为21世纪的小主人,就应该从小弘扬民族精神,长大成为全面建设小康社会,实现中华民族伟大复兴贡献力量的人。
民族精神是一个国家,是一个民族兴旺发达的精神支柱,是维系本国民族人民生存发展的根基,民族精神的核心是爱国主义。
绵延五千多年的中华文明,之所以历经磨难而不衰,饱含艰辛而不屈,千锤百炼而更坚强,就是不断丰富和发展民族精神,使之成为古往今来中华儿女奋发向上,百折不挠的精神支柱。
在《狼牙山五壮士》中,五壮士为了掩护群众和连队转移,与敌人进行殊死搏斗,最后在弹药耗尽的情况下,宁死不当敌人的傀儡,英勇跳崖,壮烈牺牲。
他们不畏牺牲,宁死不屈,热爱祖国的精神无不体现着我们中华民族伟大的民族精神。
我们要像五壮士一样弘扬民族精神,不屈不挠,立志成才,争做四有新人,做个了不起的中国人,时刻准备着建设我们了不起的国家。
同学们,从自己做起,从现在做起,从一点一滴做起吧
把对祖国,对人民深厚的爱,把个人的理想,心愿和报复,化为立志图强,报效祖国的实际行动,为实现全面建设小康社会的奋斗目标添砖加瓦
为祖国明天的辉煌而努力奋斗

求一篇关于诚信的短篇演讲稿
2Food security under threat: global response needed Climate change and commodity speculation are among the main factors threatening food security inside and outside the EU, according to a European Parliament resolution adopted on Thursday. MEPs call for urgent measures to combat food price manipulation and ensure that food production is maintained in the EU. Droughts, floods, fires and storms, on a greater scale than in the past, are reducing agricultural capacity all over the world, says the resolution. Soil and water management must be improved to prevent loss of farmland, and the Commission should monitor national climate change mitigation measures, believe MEPs. Tackling speculationMEPs criticise speculation in food commodities, agricultural raw materials and energy markets, all of which puts food security at risk. The G20 is urged to work for the convergence of market regulations by involving countries that are not part of the G20 in the fight against food price manipulation.Parliament asks the Commission to consider giving the new European Security and Markets Authority more power to prevent abuses in commodity markets. Dealing in food commodities should be limited to investors who have a genuine link with agricultural markets, MEPs believe.In addition, MEPs call on national governments not to impose curbs on exports, as these provoke greater uncertainty in the markets and disrupt world markets, and therefore have the potential to drive prices up further at global level. Helping EU farmersTo guarantee food security in the EU, a strong Common Agricultural Policy is needed, says the resolution. Declining farm incomes, caused by higher production costs to meet health, environmental and animal welfare standards, need to be urgently addressed to ensure there are farmers in the EU in the future. Market intervention tools, such as intervention and strategic stocks, must be part of the policy, says Parliament.Support for farmers in developing countriesSince agriculture is a key economic sector in the developing world, MEPs call for a larger proportion of the financial aid for this sector to be used to support more effective and sustainable farming practices. They add that land ownership should be promoted to reduce poverty and increase food security.The resolution was approved by show of hands. 3New threat to global food security as phosphate supplies become increasingly scarceA new report from the Soil Association reveals that supplies of phosphate rock are running out faster than previously thought and that declining supplies and higher prices of phosphate are a new threat to global food security. ‘A rock and a hard place: Peak phosphorus and the threat to our food security’ highlights the urgent need for farming to become less reliant on phosphate rock-based fertiliser. [1]Intensive agriculture is totally dependent on phosphate for the fertility needed to grow crops and grass. Worldwide 158 million tonnes of phosphate rock is mined every year, but the supply is finite. Recent analysis suggests that we may hit ‘peak’ phosphate as early as 2033, after which supplies will become increasingly scarce and more expensive. [2]This critical issue is missing from the global policy agenda - we are completely unprepared to deal with the shortages in phosphorus inputs, the drop in production and the hike in food prices that will follow. Without fertilisation from phosphorus it has been estimated that wheat yields could more then halve in coming decades, falling from nine tonnes a hectare to four tonnes a hectare. The current price of phosphate rock is approximately twice that of 2006. When demand for phosphate fertiliser outstripped supply in 2007\\\/08, the price of rock phosphate rose 800%.In Europe we are dependent on imports of rock phosphate, having no deposits of our own, but the geographical concentration of reserves adds further uncertainty to the future security of our sources. In 2009, 158 million metric tonnes of phosphaterock was mined worldwide. 67% of this resource was mined in just three countries - China (35%), the USA (17%) and Morocco and Western Sahara (15%). China has now restricted, and the USA has stopped, exports of phosphate. [3]Author of the report, Dr. Isobel Tomlinson, said: A radical rethink of how we farm, what we eat and how we deal with human excreta, so that adequate phosphorus levels can be maintained without reliance on mined phosphate, is crucial for ensuring our future food supplies.‘A rock and a hard place’ sets out the actions needed to close the loop on the phosphorus cycle. These include:Changing how we farmDifferent farming systems vary enormously in their reliance on mined phosphate. Organic farms are more resilient to the coming phosphorus rock ‘shock’, as it can only be used as a supplement to nutrient recycling (including crop rotations, green manures, and composting), and not as a replacement. Organic crops generally have a lower fertiliser requirement than non-organic crops, with a greater capacity to scavenge for nutrients through denser and deeper root systems.Changing what we eatEating less meat can reduce the demand for mined phosphate. This is because vegetable-based production is more efficient in its use of phosphorus then livestock production. Although different types of meat have different levels of mined phosphate demand depending on the farming system used to produce them. Meat from livestock grazed on grassland that has not been fertilised with artificial fertilisers, will perform much better than meat from livestock grazed on fields that have been, or livestock fed on grain grown using artificial fertilisers.Changing how we deal with human exretaThe report recommends a radical change in the way we treat human exreta and the need to abandon our current ‘flush-and-forget’ toilet systems in favour of Ecological Sanitation. The report also calls for a change to EU organic regulations to allow the use of human sewage – rich in ‘natural’ phosphate - on agricultural land to ensure phosphate levels are maintained. Globally only 10% of human waste is returned to agricultural soils. Urine alone contains more than 50% of the phosphorus excreted by humans.
