【答案】Civilized Behaviors on CampusGood afternoon，teachers and students.I feel honored to make a speech here.My topic is "Civilized Behaviors on Campus".
We often notice that there are some uncivilized behaviors in our daily life on campus，such as spitting everywhere，talking loudly，littering ，swearing in public places，etc.Not only do such uncivilized behaviors have a bad effect on the development of us teenagers physically and mentally ，but also damage the harmony of school life.
How can we cultivate civilized behaviors？The first important thing is to be polite students and always ready to help others .At the same time，we should keep the school environment clean and never destroy plants such as flowers，trees and grass.Most importantly，we are supposed to work hard and obey school rules.
That's all.Thank you!
