吸烟有害健康的英语演讲稿（通用3篇）
Good afternoon, everyone!
Iam very glad to have a speech here. My name is , 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 University, and now, I am studying in 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!
尊敬的各位老师，亲爱的同学们：
大家好！
今天我国旗下讲话的主题是《拒绝吸烟，倡导文明生活》 。20xx年5月31日是世界卫生组织发起的第xx个世界无烟日。相信每个同学一定都知道，烟草是危害当今世界最严重的公共卫生问题之一，是人类健康所面临的最大危险因素。尽管如此，但目前全球仍然有约13亿的吸烟者，每年因吸烟导致死亡近500万人。
大量的科学研究证明 ，吸烟对人体健康的危害十分广泛。所有烟草中均含有可导致人体发生多种致死性和致残性健康问题的毒素;吸烟者患癌症，尤其是肺癌、心脏病、肺气肿及其他致死性疾病的危险性会明显增加。据世界卫生组织调查显示，全球每6.5秒就有一人因吸香烟而失去生命，香烟已成为继高血压之后的第二号杀手，有80%的肿瘤，75%的慢性阻塞性疾病和25%的冠心病都与香烟有关。
同学们，听到这么多如此令人震憾的数字时，难道你们还无动于衷吗?难道你们还要一次次诡异的冲进厕所，偷偷摸摸，胆战心惊地过过烟瘾，沉寂在那烟吐云绕的所谓快感之中吗?难道还要在校外，嚣张地吞云吐雾，谈笑风生，如入无人之境吗?
人的生命只有一次，是父母的给予和上苍的恩赐，它承载着你的亲人，朋友和整个社会赋予你的责任。因此，请珍爱你生命中的每一天，从今天开始，放弃香烟，热爱生命，创造美好的人生!只有用心去感悟和体会人生，你才会真正懂得生命的美丽。
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.
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.
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.
