參考范文：
Good morning, boys and girls!
The topic of my speech today is “Learn to express thanks”. We find some students want to eat well and wear fashionable clothes at school. When they leave school and enter society, they don’t know how to show any sense of thanks.
I think this behavior is not correct. As students, we should learn to express thanks. The society offers us a chance to receive good education. And our parents also support us to go to school. Our teachers teach us much knowledge, so we should thank them. We should also thank our friends because they can always give us courage and help.
In the future, we should never forget our society, parents, teachers and friends. At present, we should study harder to make our world more beautiful. Thank you for your listening!
