　　The Top Meal of the Day

　　What do you have for breakfast? Do you go to school with a big breakfast ?

　　Breakfast is very important, especially for students who are under lots of pressure from studies. A survey shows that eating a good breakfast can improve students’ schoolwork. Also it can help them do better in sports.

　　Some students don't eat breakfast because they don't have enough time. As a result, they are likely to get tired easily and become fatter. They may even have problems in the stomach. Skipping breakfast not only has bad effect on students’ studies, but also does harm to their health.

　　I think breakfast is the top meal of the day, and we should never skip it. If we are really in a hurry, we should put some bread, fruit and a bottle of milk in our school bags

　　Breakfast gives us enough energy for schoolwork. Don't skip it from now on!
