　　Every morning we have to go to school very early, so many of us don't have breakfast. It's very bad for our health. In the morning we usually have four classes. It's a long time before lunch. If we don't eat anything for breakfast, we may feel hungry and we can't listen to the teacher carefully. We need energy very much while we are growing. I really think that we should have a good breakfast.
