　　Ⅴ. 【参考范文】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 them. Using an iPod , we can listen to music, download a lot of learning materials and read them on the screen. Apparently, it is helpful to our study, especially to our English listening.

　　Some students, however, bring their iPods to classroom and listen to music with earphones, which makes the teacher and other students greatly annoyed. What’s worse, some of them even waste precious time in class playing video games.

　　In my opinion, as a student, we should make good use of iPod to help achieve academic success. Classroom is a place for students to study, and therefore concentration is 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
