A survey about smokers in a middle school tells that although 90% of all students never smoke, 3% of them often smoke and 7% sometimes do. In other words, 10% of the students smoke. That s terrible.

　　As we know, smoking is harmful to our health. Every year, thousands of people lose their lives because of it. Smoking not only does harm to your health, but also wastes money. Because, a fire may be caused by cigarette ends. It s a pity to learn that one ends in death by smoking.

　　In all, smoking is so dangerous that we should keep away from it.
