Dear friends,

I am Li Ming, president of the Students’ Union. I am writing to call on you to give up smoking.

Some students in our school have been caught smoking, which has become a cause of concern. Medical studies show that smoking is harmful to our health because of the poisonous chemicals produced when cigarettes are burning. Both smokers and non-smokers are affected by the poisonous matter. So the number of people who suffer from lung cancer and other breathing-related diseases has been on the increase. Therefore, smokers should give up this bad habit as soon as possible.

Let’s develop a healthy lifestyle! Let’s take action from now on!

Li Ming
