Smoking It is known to everyone that srnoking is harmful to our health. Research conducted in many countries has indicated that smoking causes lung cancer, heart disease and various respiratory illnesses. Responding to overwhelming medical evidence of the harnful effects of smoking, many governments have taken actions to reduce tabacco consumption. Some have imposed heavy taxes on tabacco products, others have conducted anti-smoking campaigns.In theatres,cinemas and some public places nonsmoking is often demanded by authorities. However, none of the governments have even considered prohibiting the sale of tobacco. This is due partly to the political power of the big tobacco companies and partly to the fact that so many people, particularly in influential position in society, are habitual smokers. Tobacco farmers and workers are also strongly opposed to legislation. In fact, smoking is not only a matter of habit but also a matter of profits. 吸 烟 众所周知吸烟有害健康。许多国家的研究表明吸烟引起肺癌，心脏病和各种呼吸道疾病。 为了对吸烟的有害影响作出反应，许多国家政府已经采取措施减少香烟消费。一些国家对烟草产品增加了重税,还有一些国家组织了禁烟运动。在剧场,影院和一些公众场所，当局经常要求人们不要吸烟。
