Will it matter if you don’t take your breakfast?

Recently a test was given in the United States. Those tested included people of different ages, from 12 to 83. During the experiment, these people were given all kinds of breakfasts, and sometimes they got no breakfast at all. Special tests were set up to see how well their bodies worked when they had eaten a certain kind of breakfast. The results show that if a person eats a proper breakfast, he or she will work with better effect than if he or she has no breakfast.

This fact appears to be especially true if a person works with his brains, if a student eats fruit, eggs, bread and milk before going to school, he will learn more quickly and listen with more attention in class. Opposite to what many people believe, if you don’t eat breakfast, you will not lose weight. This is because people become so hungry at noon that they eat too much for lunch, and end up gaining weight instead of losing. You will probably lose more weight if you reduce your other meals.

小题1:The results of the test show that ______

A.breakfast has great effect on work and studies.

B.breakfast has much to do with people’s health.

C.a person will work better if he has simple breakfast

A.do your work badly

A.one can work better with breakfast.
