     Will it matter if you don't take 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.D   1   the test,these people were given

all kinds of breakfasts and s   2   they got no breakfast at all. Scientists wanted. to see how w   3   their

bodies worked when they had different kinds of breakfasts.

     The results show that if a person eats a right breakfast, he or she will work b  4   than if he or she

has no breakfast. If a student has fruit,eggs,bread and milk before going to school,he will learn m   5_

quickly and listen more carefully in class.

     The results also show that having no breakfast will not help you lose weight. This is because people

become so hungry at noon t   6__they eat too much for lunch. So they will gain weight instead of losing

weight.
