Smoking and Health Good morning/afternoon！My dear judges and teachers . I'm very glad to stand here again. This time my topic is Smoking and Health. In some countries, people can't smoke on trains and in their workplaces any more. Hospitals and department stores are also becoming smoke-free. Some businesses say that no one can smoke in any of their offices. Some governments have banned smoking in all public places. It won't be very long until smoking is not allowed anywhere in public places. For some people, smoking has become a daily habit. They believe that smoking can make them happy and help them relax. Some young people even think that smoking is cool, and is a fashion of the day. These ideas are foolish and wrong. Smoking is harmful not only to our health but also to the environment. It damages nearly every organ in the human body. It is linked to least 15 different cancers, and accounts for about 30% of all cancer deaths. It is a main cause of lung cancer and mouth cancer. When a person smokes, people around him are forced to breathe in the smoke, and become passive smokers. Smoking affects non-smokers more than it does to smokers. Passive smokers are easier to get ill than smokers. So, many non-smokers are against smoking and more and more people do not like to stay in a place where somebody is smoking. Smoking also has many other bad effects. Burning cigarette ends may cause fires. And cigarette ends here and there make the place dirty. Smokers have to spend a lot of money on cigarettes. If they stop smoking, they can save the money to do other things. Nowadays, there is an anti-smoking movement all over the world. In China, many cities have passed laws to stop smoking in public areas, such as buses, cinemas, schools and office buildings. In places where people may not smoke there is always a sign. The sign says "Thank you for not smoking”", which means“ Smoking is not allowed here!” That s all. Thanks for listening! 本文来源：https://www.wddqw.com/doc/3868bc37961ea76e58fafab069dc5022abea4631.html
