Smoking may be a pleasure for some people.  1 ,it is a serious sourceof 2 for their fellows. Now medical authorities express their 3 about theeffect of smoking 4 the health not only of those who smoke but also those whodo not . 5 ,nonsmokers who must 6 inhale the air polluted by tobacco smoke may 7 more than the smokers themselves.

　　As you are 8 informed, a considerable number of students have 9 in aeffort to 10 the university to 11 smoking in the classroom. I believe they are 12 right in their aim. However, I would hope that it is 13 to achieve this bycalling 14 the smokers to use good judgment and show concern for other 15 thanby regulation.

　　Smoking is 16 by city bylaws in theatres and in halls used forshowing films as well as in laboratories where there may be a fire hazard. 17 ,it is up to you good 18 .

　　I am therefore asking you to 19 “No smoking” in the auditoriums,classrooms and seminar rooms. This will prove that you have the nonsmoker’s health andwell-being 20 ,which is very important to a large number of our students.
