【正确答案】
The prohibition of smoking in public places is a very good rule. Not only will it improve people's health, but also reduce conflicts.
Banning smoking is of great help to our health. Smoking in public places can make people young and old, who are reluctantly involved, sick because these victims may be allergic to smoking. In that case, the non-smokers will be forced to quit talking, even quit their jobs if they are victims in office buildings. This is unfair! Therefore, non-smokers will be greatly pleased to ban smoking in public places and their health will be ultimately improved. Prohibiting people from smoking can also reduce interpersonal conflicts. Generally speaking, non-smokers are very inclined to get extremely annoyed when confronted with the heavy smokers; while smokers are frequently complaining about whether they should be entitled to smoking in public when faced with the disapproval on criticisms of non-smokers. The proper way is to weigh the impact of smoking in public places so as to diminish conflicts if people are thoughtful for each other, consequently, the relationship between people will be harmonious.
To sum up, to ban smoking in public places is a priority. It will benefit smokers and non-smokers alike.
