全世界人们在每年的5月31日庆祝世界无烟日。世界无烟日是由世界卫生组织在1987年设立的，目的是向全世界人民展示吸烟的危害，另一个目的是鼓励人们停止吸烟，以此减少吸烟对健康的危害。每年大约有540万人死于吸烟相关的疾病。在世界无烟日，世界卫生组织为那些帮助人们，特别是儿童禁烟做出过巨大贡献的组织和个人颁发特殊贡献奖。2008年，世界卫生组织号召全面禁止烟草广告，并声称烟草广告是导致人们吸烟的最大因素之一。

　　Tobacco is a dangerous drug. It's amazing how governments allow people to use tobacco. One reason is governments get a lot of money from taxes on cigarettes. Another reason is tobacco companies have a lot of influence on politicians. Tobacco-related health problems put a huge amount of pressure on a country's healthcare system. Millions of working hours are lost every day because people take smoking breaks. The saddest thing is that children lose parents because of the damage tobacco did to their bodies. Tobacco contains nicotine and other poisonous chemicals. These cause many diseases, like heart problems and cancer. Smoking causes bad breath, disease, loss of energy, and it's expensive. It's time for the world to quit smoking.

　　烟草是一种危险的药草，令人惊异的是政府允许人们使用烟草。一个原因是政府可以从香烟上征收大量的税，另一原因是烟草公司对政客有巨大的影响。与烟草相关的疾病对国家的卫生保健系统造成了巨大压力。每天的吸烟休息时间造成数百万小时工作时间的流失。最悲哀的是，父母吸烟造成身体损害，使得孩子们早早就失去了父母。烟草含有尼古丁和其他有害化学物质，这些物质会引发许多疾病，如心脏疾病和癌症。吸烟导致口臭，易生病，体力下降，而且烟草价格昂贵。全世界的人们是时候戒烟了。
