　　My good habit is early to bed and early to rise.Two years ago, when I was a Grade 7 student, I liked reading books in bed.Every day after I finished my homework, I lay in bed until 24:00 o’clock.The next day I couldn’t get up on time.I used to be late for school,and I felt tired in class.It was too bad.With the help of my teacher and my parents, I gave up the bad habit.Ever since then, I go to bed early and get up early.I never go to school late again.As a result, I’m much stronger and doing better in school now.
