Dear Tom:
It is regretful for you to not finish your homework everyday.As we all konw,Diligence is the mother of good luck.So,if you want to succeed,you had better to follow my advice.First,you must understand the importantce of study,and set up your interest for study.Sencd,you should attentively follow your teachers on lessions so that you can do your homework by yourself.Third,when you go home,you should do your homework at once,you can tell yourself,if you not finish your homework,you can not play and do anything.What'more,if you can not do your homework,you can ask help for your parents,firends,teachers and so on,you should not give up.Last but not least,you must remember that learing is first for a student always,don't let otherthing take up your too much time and energy.
I hope my advice can help you and I can quickly hear good news from you.Study hard!
Best whiches for you.
yours,XX.
