第一篇：年级演讲稿300字

今天，我给大家演讲的是《我的中国梦》，从小我就是一个爱做梦的男孩子，我梦想着自己能上天入地，自由自在。渐渐长大，我的梦想是，当一个旅行家，游遍中国的山山水水，在草原飞驰，在大海遨游，在长城放飞我的梦想。上学了，老师教导我们：梦要更高更远，不能只有自己，不能只有小家，还要有大家，更要有国家，有国家的梦才更高远，更伟大。于是，中国的梦就成了我们的梦，我的梦就是中国梦!小梦连着大梦，一个个小梦想叠加起来，就组成国家的梦!

我想成为一名翻译家，把中国所有著作翻译成英文。为了实现这个梦想，我要认真的学习英语，此外，我还要深入了解中国的古文化和历史，外国人通过我的翻译，会更多的了解到中国的四大传说、唐诗、宋词、元曲等等，弘扬中国文化，成为一个文化使者; 我还要穿上太空衣，乘坐太空船，飞到遥远的太空，去开设太空课堂，向外星人介绍我的祖国――具有五千年文化底蕴的中国，让宇宙每一处都篆刻着一个响亮的名字――中国。

中国梦，让我们的祖国民富国强，让每一个人都拥有爱和自由。为了实现自己的每个梦想，我们必须像蜜蜂那样付出辛勤的劳动，必须像雄鹰那样奋勇拼搏。来吧，让我们大家从今天做起，一起努力学习吧!来实现我们自己心中美丽、骄傲的梦!

梦想+坚持=成功，我的中国梦必会实现!

第二篇：18300字演讲稿

Good evening, Ladies and Gentlemen:

I’d like to start with a group of pictures.

"Modern and advanced"? This society forgets, and ignores the other two thirds of human beings. It's far from the ideal! We call ideal as a utopian, a place where reality does not exist. A few people still look forward to the ideals. We make fun of them, considering they are naive. Will we still be content to live in such a society, if misfortune drops to us? No! Of cause not!

When we feel the warmth of the sun, these people, endure great sorrows and pains. Can we imagine that? They are our brother and sisters!

Facing them, will we still complain about our own misfortune?

Facing them, will we still have the mood shouting for our own freedom? Facing them, will we still want to have more and more unnecessary stuff?

They are unable to meet their needs, even the basic needs of survival! Everyone, as a member of humanity, shouldn't feel ashamed? Our luxury deprived their lives, our indifference violated our soul, and our barbarity destroyed human civilization!

What's the ideal society? It's a society no one worries about their living, a society no one is refused from education, a society everyone can pursue his/her own happiness! The ideal society is filled with love, joy and kindness. In that society, we can touch the other's hearts, we can share our dreams and most important, we can just be the true men!

Let's break the ethnic divide, bridge the gap between rich and poor, hand in hand, to build a Great wall, protecting us from evil; to construct a steady bridge, connecting reality to the ideal society! Let's pursue for that, that's the only way to the bright future! They are watching us! Thank you!

Smoking is a greater cause of death and disability than any single disease, says the World Health Organisation.

According to their figures, it is responsible for approximately five million deaths worldwide every year.

Tobacco smoking is a known or probable cause of approximately 25 diseases, and even the WHO says that its impact on world health is not fully assessed.

Heart attack and stroke

UK studies show that smokers in their 30s and 40s are five times more likely to have a heart attack than non-smokers.

Tobacco contributes to the hardening of the arteries, which can then become blocked and starve the heart of bloodflow, causing the attack.

Often, smokers who develop this will require complex and risky heart bypass surgery.

If you smoke for a lifetime, there is a 50% chance that your eventual death will be smoking-related - half of all these deaths will be in middle age.

Smoking also increases the risk of having a stroke.

Lung problems

Another primary health risk associated with smoking are lung cancer, which kills more than 20,000 people in the UK every year.

US studies have shown that men who smoke increase their chances of dying from the disease by more than 22 times.

Women who smoke increase this risk by nearly 12 times.

Lung cancer is a difficult cancer to treat - long term survival rates are poor.

Smoking also increases the risk of oral, uterine, liver, kidney, bladder, stomach, and cervical cancers, and leukaemia.

Another health problem associated with tobacco is emphysema, which, when combined with chronic bronchitis, produces chronic obstructive pulmonary disease.

he lung damage which causes emphysema is irreversible, and makes it extremely difficult to breathe.

Harm to children

Smoking in pregnancy greatly increases the risk of miscarriage, is associated with lower birthweight babies, and inhibited child development.

Smoking by parents following the birth is linked to sudden infant death syndrome, or cot death, and higher rates of infant respiratory illness, such as bronchitis, colds, and pneumonia.

Nicotine, an ingredient of tobacco, is listed as an addictive substance by the US authorities.

Although the health risks of smoking are culmulative, giving up can yield health benefits regardless of the age of the patient, or the length of time they have been smoking.

Future impact

By 20xx, the WHO expects the worldwide death toll to reach 10 million, causing 17.7% of all deaths in developed countries.

There are believed to be 1.1 billion smokers in the world, 800 million of them in developing countries.

第三篇：演讲作文300字

二年级下年级下学期的时候，我参加了校园金话筒。演讲选拔赛的题目是“百鸟朝凤”。

比赛的前几天，我非常努力的作准备，背呀背，背呀背，终于背得熟练了。但有的字背错了字，还看了看时间，用了两分钟零五秒，所以我要缩短时间。

到比赛那天，我非常紧张，手都发软了，手水都是汗，生怕自己是第一个演讲，我在倒数第三上场，过了一会儿就听到我的名字了。

我非常紧张地走上演讲台先作息我介绍，接着说出演讲的题目是：百鸟朝风。然后开始背了。但我背了一个字，反正都是一个意思。终于背完了，但老师说：“你背得非常棒，你通关了。”我听了非常高兴。

比赛前，我以为难过关，但着次背过关来了。觉得非常简单。都是我努力背诵的结果。我懂得了做任何事，只要努力都能成功。

第四篇：四年级演讲稿

尊敬的老师，亲爱的同学们：

大家好！我是来自四年一班的周依琳。今天我演讲的题目是“我和书的故事”。

说起我和书的故事，最初的记忆是在三、四岁的时候，那时我还不能独立阅读只有文字没有图画的书，都是爸爸妈妈读给我听。《骑鹅旅行记》就是这样听完的。当故事的最后尼尔斯变回人形，回到父母中间，却再也听不懂大雁的语言了，我为他高兴，同时也为他和动物们的分离难过。

随着年龄的增长，我拥有了许多书，并逐渐感悟到了书的魅力：有时，它让我哈哈大笑，有时让我感到悲伤。我曾和孙悟空一起降妖除魔，跋山涉水；和福尔摩斯一起侦破连环谜案；我感慨鲁滨孙的坚韧和智慧；执着于海底两万里的惊险；还有桃园三结义的侠肝义胆，以及蔡波波的聪明漂亮，马小跳的淘气顽皮------，这些书里的人物都给我以启迪：善良、坚韧、智慧、乐观------

就这样，我和书成了好朋友，随影随行；但是，因为贪玩，偶尔我也对书朋友很冷漠,几天也不看他一眼，书独自呆在书架上，好像很寂寞，这时的我就再也忍不住了，把它抱起来津津有味地读起来。相信在我成长的路上，我和书朋友会配合默契,我也会不断进步。

古人云“鸟欲高飞先振翅，人求上进先读书”，同学们，让我们读书吧，多读书，读好书，去挖掘这座无尽的宝藏！

第五篇：竞选班干部的演讲稿300字

尊敬的老师、亲爱的同学：

大家好!

今天，我站在讲台上的目标就是争当“班级元首”——班长。班长是一个多么令人向往的职位，当然，我也渴望当上这个名副其实的班长。我想当班长有一个非常重要的原因是因为我有很多经验，小学五年的班长和大队部部长职位就锻炼了我的组织能力。在班干部职务面前，我自信，我能干、我还有责任心。

有人说过当班长是很风光的，没错，但我知道风光的背后更多的是辛勤的汗水。我很外向，善于同其他同学沟通交流，而且我有一副好口才，很善于去说服别人。

如果我当上了班长，我会做同学的好榜样，做老师的好助手。我会用自己的实际行动证明自己的能力。既然是花，我就要开放;既然是小树苗，我就要长成一棵苍天大树;既然是石头，我就要去铺出大路;既然是班干部，我就要成为一名出色的领航员!

我不敢说我是最合适的，但我敢说我将会是最努力的!

我不愿做温室里的花朵，要做傲雪的梅花，经受各方面的锻炼和考验。一个班级的优秀来自班干部的领导和全体同学的共同努力。如果大家对我有任何意见，请不要畏惧我，尽管向我提出，我一定接受并改正。

我自信在同学们的帮助下，我能胜任这项工作，正由于这种内驱力，当我走向这个讲台的时候，我感到信心百倍。我努力，我能行!请相信我，给我一次锻炼的机会!

希望你们能投我珍贵的一票!

谢谢!

第六篇：演讲作文300字

“尊敬的老师，亲爱的同学们，大家好……”咦？这是在做什么呢？哦，原来是这样。

今天是我们班举行演讲比赛的重要日子，是第二单元口语交际的内容。第一个上去演讲的是邵子善，第一个肯定会紧张。他此刻正如热锅上的蚂蚁――充满着焦虑与不安。他双手拿着稿子，走上讲台，鞠了一躬，深深地吐了一口气。然后，开始演讲。刚说完开幕词，下一句就忘了，他连忙低下头去看稿子，再磕磕巴巴地说出来。这一系列的动作引得大家哄堂大笑。同学们最后对邵子善的点评也不太好。

我们组的程靖涵是最后一个上场的。一听轮到他了，我们全组都为他捏了一把汗。他站上讲台，单手拿稿，随着一个问题的提出，演讲也开始了，我可以清晰地看出他有一点小紧张，就像一根紧绷的弦，好在他最后没有掉链子。

演讲比赛特别精彩，仔细回味起来，别有滋味。
