Dear fellow students,                                                   
     Our school is aimed to build a “harmonious campus” .                  
As a high school students, we should behave ourselves. But           
some students are badly behaved. They threw rubbish about              
and listen MP3 or sleep in class. A few boys even smoke and copy       
other students homework. I think it has a bad effect on their health as 
good as their study. A “harmonious campus” should have civilized      
students. So we should be strict on ourselves. Of course, study is the 
first. But we should study hardly. In order to build a harmonious       
study atmosphere, they must develop good habits. If everyone           
makes a contribution to build our campus, I’m sure                   
our school will become beautiful or harmonious.                                                          
Yours,
