These days more and more middle school students are smoking (吸烟). They don't listen to their teachers, parents or classmates and they smoke anywhere they can't be seen—on the way to school, in the dormitory (宿舍), or even in the washroom. And most of them think smoking is very cool looking. But I want to tell you my story and you'll see that it is wrong to smoke at our age. My friends at school smoked and they asked me to have a try. So I started smoking when I was a fourteen-year-old boy and after a month I couldn't stop. But two years later I felt what smoking was doing harm 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 (香烟) and also you may get some badbehaviorsand habits such as stealing (偷盗) and telling lies (谎言).
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.
