Good morning，everyone!It's my honor to be here to make a short speech．

Recently I have found that some of our classmates can't study effectively．Some can't help falling asleep in class，because they often study too late into the night．Others seldom have sports，which surely does harm to their health．
As we know，enough sleep is of great importance for us senior 3 students．We can concentrate our mind in class with sufficient sleep，so we should try to make wise use of our time，striking a balance between work and leisure．Besides，doing proper exercise every day can benefit us a lot，keeping fit，reducing stress and so on．Let's spare some time to do all kinds of sports．And only in this way can we keep a good mood and study well．
