      What will happen if you don't eat your breakfast? A short time ago,a test was given in the United

States.People of different ages,from 12 to 83,were asked to have a test.During the test,these people

were given all kinds of breakfast and sometimes they got no breakfast at all.Scientists wanted to see

how well their bodies worked when they had had different kinds of breakfasts.

     The results show that if a person eats a right breakfast,he or she will work better than if he or

she has no breakfast.If a student has fruit,eggs,bread and milk before going to school,he will learn

more quickly and listen more carefully in class.

people become so hungry at noon that they eat too much for lunch.So they will gain weight instead

of losing weight.
