【答案】Dear teachers and students，
I'm privileged to give you a speech.Admittedly，we are a generation in a new era.On our shoulders lie new challenges and responsibilities.So we need to sweep away all the uncivilized phenomena in our school first.
Some students take it for granted to waste food.Besides，in the library，certain students speak or talk aloud，disturbing and annoying others.Little as the matters seem to be，we cannot afford to overlook the serious consequences they will bring.So I suggest that the school post more noticeable slogans and make relevant rules to help students get rid of those uncivilized behaviors.
As students in the new era，I sincerely hope that we can become better to make contributions to the society.
