Dear headmaster,
Yours,
Li Ming Recently I’ve found that some of my roommates smoke in the dormitory. The air in the room is always made very dirty. I suggest that we should forbid smoking in our school, as smoking causes many problems. First, smoking pollutes our fresh air and even leads to serious diseases. Secondly, smoking can invite being bored, affecting friendship between classmates. Next, it’s a great waste of money buying cigarettes .Finally, it will take a lot of time to smoke, which, of course, affects our studies greatly.
