我有一个坏习惯 I Have a Bad Habit
I have many bad habits, but there is one always makes me upset. I like nodding off in class. Nearly everyone will have this bad habit in summer. But I will nod off in every class and every season. Usually, I will nod off when the class begins about ten minutes. I hate this. I have tried my best to correct it. But I failed in the end. This habit troubles me lot.
