Dear Headmaster，

【答案】Dear Headmaster，
    Recently，I have become worried about the environment of the school dining hall.Some people seem to treat it as if it were a rubbish area．They throw the leftover food about，on the table or on the ground．This makes the hall look unpleasant for us to come and eat there．
    I have several solutions．First，get more people to form good habits by putting posters around the hall，asking them to be more thoughtful of their behaviors and protect our environment．Second，make people pick up their own litter．We can do this by asking some students to walk around the hall and watch out for those that drop litter．We can make those who are found dropping litter stay behind and tidy up the hall after all the students have finished their meal．I hope you find my ideas useful．
    All in all，I do hope we can have a better dining hall，so that the students and the teachers can enjoy their lunch every day．
Yours sincerely，
Li Hua
