Smoking is harmful to our health, but many middle school students are smoking. Their teachers, parents or classmates can't stop them because they smoke anywhere they can't be seen --on the way to school, in the dormitory , or even in the washroom.And most of the students think that smoking is very cool.But I want to tell you my story and then you will see that it's wrong to smoke when you are very young. When I was a middle school student, my friends at school smoked and they asked me to have a try. So I started smoking when I was fourteen. Soon I couldn't wait to smoke as soon as I was free. After a month I couldn't stop smoking. But two years later, I felt what smoking was doing to me. I couldn't run far, I coughed every morning, and I got very weak. So I wanted to stop smoking. It wasn't easy, but now I have stopped it, and I feel better. If you smoke, you will get ill more easily, and perhaps you can't grow taller, because there is something bad in cigarettes and also you may get some bad behaviors and habits such as stealing , _ and having a fight with others. So you can see smoking is a bad habit. If you smoke, try to stop. Though it isn't easy, you must do it as soon as possible. The writer stopped smoking. It's NOT because   _  .
