Dear Benson，

I'm glad to wile to you agin．I'd like to alk about my touble I'm facing these days．

　 I don't get enough sleep ． I have less than 7 hours'sleep each night ． I think there are several reasons for this ． First of all ， the students are burdened with too much homework ． Another important reason is that schools and parents pay less attention to the children's sleep ． The children need 8 hours'sleep every day ． If the students do not have enough sleep ， they will be sleepy in class ． I often feel tired in class and my teachers are angry with me ． My grades are going down ， and my parents are worried ， too ．　

I don't know what I should do．Could you please give me someadvice？Write to me soon．

Yours，
