some of my classmates think that smoking does harm to our health.many people become ill and die of smoking.on the other hand,you must spend much money on cigarettes.what's more,many fires are caused by careless smokers.
some others take the different view that smoking will not only make you feel better but help you think especially when you are writing.they also hold that smokers seem to have an easy manner.above all,smoking can increase tax for our country.
i'm against smoking.in my opinion,it's better for those who have got into the habit of smoking to give it up.
