Dear headmaster，I'm a student of Grade 9．I want to tell you something．In our school，many students have mobile phones．They think it's（92）coolto have a mobile phone．Yes，the phones let students talk with their parents and friends at any time．But I don't think it's good for students to use them at school．Many students spend lots of time in（93）sendingmessages by mobile phone，some students even use them to play games in class or cheat （作弊） in the exams．Some students always hope to buy the new or（94）expensivemobile phones and this will（95）wastetheirparents'money．And my father tells me that most mobile phones can cause （引起）many health（96）problems．Could you do something to stop it？
Yours，Sophia．
