During the holiday,I always go to the community library with my friends. But there is always a lot of people smoking in the corner of the library. As is known to all is that nobody should smoke in the library. Although they always smoke in the corner, it still has a great influence on the citizens who are reading in the library.First of all, smoking is harmful to health. Smoking is not only hurting themselves, and damage others. The studies didn't just point to the ill effects of smoking on those who smoke--non-smokers, too, are apparently affected by the smoke from their friends, family members and strangers who light up in their presence. A steady stream of reports documented the statistical risks of contracting cancer or suffering from heart disease, even if you've never put a cigarette to your lips. We should give more impetus to the drive to make workplaces and other public areas smoke-free. It’s clear that the smell and smoke of cigarette smoke may destroy the atmosphere of study.In my opinion, the library can recruit volunteers to go on patrol. And volunteers can stop smokers smoking in time. Besides, No Smoking Signs should be posted in the corner and WC. In this way, conditions should be better
