Dear Editor,
I’m a senior high school student, named Li Hua. Now many students
have iPods and think it’s a fashion to use it. Using an iPod , we can listen
to music, downloading a lot of learning materials and read them on the
screen. Apparently, it is helpful to our study, specially to our English listening.
Some students, however, take their iPods to the classroom and listen to
music with earphones, which make the teacher and other students greatly
annoyed. What’s worse, some of them even waste the precious time in class
playing video games.
In my opinion, as students, we shall make good use of iPod to
help achieve academic successes. Classroom is a place for students to
study, and therefore concentration awfully needed for us to learn  
our lessons. Furthermore, the school should make a rule to guide the
students to use iPods in a proper way.
Yours sincerely,
Li Hua
