However,keep the classroom clear everyday is not esay.Every student should make the effort to keep clear.At first,the student who is on duty should clear up the classroom .Then,after the student who is on duty clear up the room,other students may not throw anything,they have the duty to keep the classroom clear.

In a word,every student should help to keep the classroom clear.
