Will   matter if you don’t take your breakfast? Some time ago a test     (give) in the United States. The test included people of different  (age) from 12 to 83. During the experiment, these people were given all kinds of breakfast, and sometimes they got     breakfast at all. Special tests were set up to see   well their bodies worked when they had eaten  certain kind of breakfast. The results show that if a person eats a proper breakfast, he or she will work with better effect    if he or she has no breakfast. This fact appears to be  (especial) true if a person works    his brain. For example, if a student eats fruit, eggs, bread and milk before going to school, he will learn more quickly and listen with    (much) attention in class.
