     Persons who have a well-balanced diet generally have a good appetite at mealtime. How is your

 appetite? Do you ever find that you are too tired to eat a nourishing (有营养的) breakfast  in the

 morning?  If you do, you are probably not getting enough sleep. Try going to bed earlier at night and see if

 your breakfast appetite is improved.

      Do you sometimes find that you are not hungry for lunch at school? Perhaps it is because you eat the
