Smoking in public 　在公共场所吸烟
　　Not allowing smoking in public places and office buildings is a very good rule. I believe this for several reasons. Not only will banning smoking improve people’s health, it will also increase worker productivity and reduce conflicts. 
　　We all know smoking is not healthy. Unfortunately, when smokers are able to smoke in public buildings, they can make other people sick. They may work with people who are allergic to smoking, for example. In that case, the non-smokers have no choice unless they want to quit their jobs. They can only get sicker, which is unfair. Of course, banning smoking in public buildings and offices will please non-smokers. It will also improve the smokers’ health. They will have fewer opportunities to smoke, so they will smoke fewer cigarettes. 
　　Banning smoking in office buildings can also increase worker productivity. Smokers won’t interrupt their work all the time to smoke. There will also be fewer worker absences. When smokers cut down the number of cigarettes, they will get fewer smoking-related illnesses. 
　　Finally, it is a good idea to ban smoking in public places and office buildings because a ban can reduce conflicts. Non-smokers tend to get annoyed and jealous because smokers have an excuse to take frequent breaks. The most significant conflict, however, is over whether smokers have a right to smoke in public. As we have already seen, non-smokers feel they are not always given a choice. If smoking in public is allowed, they will be forced to breathe harmful air. This may violate their rights, and nonsmokers are angry with smokers because of it.
