危害的演讲稿篇1
good afternoon, everyone!
iam very glad to have a speech here. my name is xxx, and my major is chemistry. hu bei, jing zhou is my hometown, a famous city in the three kingdoms, and it is rich in rice and fish. i graduated from xxx university, and now, i am studying in xxx university. in my spare time, i often play computer games, surf on line, or travel with friends and sometimes i like being alone and doing nothing.
my topic is smoking, do you smoke? yes or no? it has been estimated that smokers have made up half of the population. and the smokers are being younger and younger, even including some middle school students, both boys and girls. nowadays, more and more people have realized that smoking can do harm to their health. however, some people still enjoy smoking. why? some of them think it is very cool that they can smoke like a famous handsome actor; some people think that they will be looked more mature when smoking. the brain workers think that smoking can bring them inspiration and the sad people may relieve themselves by smoking. is the smoking really so effectively? if smoking was as good as what they say, our life would be easier just though smoking.
in fact, smoking is a bad habit and it can cause a lot of diseases, such as tracheitis(气管炎), lung cancer and many other diseases. recent years, there are tens of thousands of people dying of smoking. meanwhile, smoking is a waste of money. besides, careless smokers may cause dangerous fires. smoking is bad for not only the smokers themselves, but also non-smokers. second hand smoking has been recognized harmful to other people. even worse, it may cause more damages for children and pregnant women.
if you are a smoker, here are some tips can help you to reduce the harm from smoking: first, you can use a filter which can prevent most of the poisonous substance breathing into your lung, such as nicotine and tar(焦油). second, drink a cup of tea when you are smoking, because tea is able to detoxify. third, you can smoke the electronic cigarette rather than cigarette. though the electronic cigarette is not completely safety, it is less harmful for health compared with cigarette. i think the most effective way to reduce the harm is that smoke as less as you can. the less you smoke, the more health you will get, and then you will live longer.
at last, considering the health of yourself and other people who you care and you care, please do not smoke!

smoking is very popular among chinese people. nowadays, the number of smokers during teenagers is increasing. some treat smoking as fashion and follow such bad behavior. though many people have been educated the danger of smoking, they still do not fear it.
吸烟很受中国人的欢迎。如今，青少年吸烟者的数量与日俱增。有些人把吸烟当作时尚，追逐这样的不良行为。尽管许多人都被教育过吸烟的`危害，但是他们并没因此而却步。
it is known to all that cancer has been the killer and the researches found that smoking for a long time will be easy to get cancer. i remembered my hometown, where people smoked a lot, especially the old generation, and they formed this bad act when they were young. then for a time, many people died of cancer. people started to worry and they found that these people were heavy smokers.
众所周知，癌症是人类头号杀手，而且研究发现，长时间吸烟很容易患上癌症。我记得在我的家乡，吸烟的人很多，特别是老一辈，他们在他们年轻的时候就养成了这个习惯。然后有一段时间，很多人死于癌症。人们就开始担心了，后面他们发现这些人都是重度吸烟者。
the sad thing is that many teenagers smoke at their young age, and they feel cool to do it. some adults smoke to relieve their pressure. no matter what kind of reasons, the fact is that smoking not only hurt themselves, but also hurt other people, because we know that second hand smoke is harmful, too. for everybody’s health and to live a better life, smoking should be stopped.
可悲的是，许多青少年在年轻的时候就吸烟，他们还觉得很酷。一些成年人用吸烟来缓解他们的压力。不管出于什么样的原因，事实是，吸烟不仅伤害自己，还伤害了别人，因为我们都知道二手烟也是有害的。为了每个人的健康以及生活得更美好，我们应该停止吸烟。
危害的演讲稿篇3
哪一个人不愿笑语长在?哪一个家庭不愿幸福美满?安全，特别是交通安全，就如一根七彩的丝线把我们这一个个美好的愿望连接起来，构成了一个稳定、祥和、五彩缤纷的美好世界。
可曾几何时，公路成了扼杀生命的无情的杀手，汽车、摩托车就像那一把把锐利的尖刀，肆意地宰割着我们这一个个美好的愿望。大家可知道?据不完全统计，伊拉克战争历时两年，死亡4万余人，而每年因车祸死亡的人数就达10.9万，这是一个比战争还要冷冰冰的无情的数字呀！交通问题如同是一块沉重的石头紧压着人们的心魂。太多太多的事故让人惨不忍睹，让人闻之撕心裂肺。多少生命因之消云，多少家庭因之破碎，有多少父母失去了孩子，有多少孩子没有了父母。一切都来得那么突然，那么残酷，那么难以置信！甚至来不及看上最后一眼，说上最后一句，巨大的悲痛就沉沉地罩住了原本一个个欢乐幸福的家庭！
在悲痛之余，我们是否想过，导致悲剧发生的一个重要原因，就是我们欠缺交通安全防卫知识。爷爷伯伯们，叔叔阿姨们，同学们，为了您和他人的生命安全，请自觉遵守交通法规，注意道路安全，并积极投身到文明交通的宣传教育中来，为深化文明交通工程尽一份责任，献一份爱心。现在，我们的各级政府部门和交警队的叔叔阿姨们都很重视交通安全问题，尤其关心我们小朋友的成长与安全，颁布了崭新的《中华人民共和国道路交通安全法》，有力地规范了道路交通，整顿了交通秩序，消除了事故的隐患。“文明交通，从我做起”，我们小学生也向所有关心我们成长的大人们郑重承诺：一定学好交通安全知识，把交通安全记心中，自觉遵守交通法规，并用我们的小手去拉爸爸、妈妈的'大手，珍爱生命，共创平安大道，共筑文明交通，共建幸福家园！

翻译：
吸烟是个坏习惯，它对吸烟者和别人都有害。很多疾病和癌症是有吸烟引起的，比如说气管炎，肺癌还有很多其他疾病。近年来，成千上万的人死于吸烟。但是仍然有很多人喜欢吸烟，因为他们认为吸烟是一种时尚，很酷，特别是青少年。
另外，吸烟也会对别人有害。二手烟是公认的对别人有害的。更糟糕的是，它会带来更多伤害。因此，人们应该牢记吸烟有害他人，那些吸烟的人应该尽可能戒烟。
危害的演讲稿篇5
各位老师，各位同学：
大家好，我今天演讲的主题是和交通有关的普(pu)法知识，首先给大家讲个小故事。
一个11岁的男孩，在一次坐公共汽车时，因为他一上车就在车上东跑西窜(chuan)，还不时的把头伸出窗外，司机多次提醒他，他都不听。汽车转弯时，男孩被摔出窗外，在送往医院的途(tu)中不幸身亡。这个故事让我联想到我们这里因为交通不便利，路况(kuang)又不好，许多小学生搭乘摩托车或者电动车或者自行车上学或放学。有的一个摩托坐3、4个学生，有的摩托驾驶员不按交通规则行驶，有的坐摩托的学生在坐车时不老实，出现了多起事故。因此我们今后要认真学习交通安全知识，懂得交通规则，自觉遵(zun)守交通规则，保护自己的人身安全。
?交通法》规定，道路行驶的机动车，必须遵守右侧通行的原则，机动车司机和前排座位乘客必须系安全带。同学们上学和放学的时候，正是一天中道路交通最拥挤的时候，人多车辆多，必须十分注意交通安全。在道路上行走，要走人行道；没有人行道的道路，要靠路边行走。集体外出时，最好有组织、有秩(zhi)序地列队行走；结伴外出时，不要相互追逐、打闹、嬉(xi)戏；行走时要专心，注意周围情况，不要东张西望、边走边看书报或做其他事情。在没有交警指挥的路段，要学会避让机动车，不与机动车争道抢行。穿越马路，要做到“绿灯行，红灯停”。穿越马路，要走人行横道线，在没有人行横道的路段，应先看左边，再看右边，在确认没有机动车通过时才可以穿越马路。不要翻越道路中央的安全护栏和隔离墩(dun)，更不能在马路上滑滑板。不要突然横穿马路，特别是马路对面有熟人、朋友呼唤，或者自己要乘坐的公共汽车已经进站，千万不能贸然行事，以免发生意外。
希望我们能认真学习《交通法》，提高保护自身的人身安全的意识。
我的演讲完了，谢谢大家。
