Dear Tom:
I'm xxx.I think you can be a good student fast.But now,I will give you some suggestions(建议) .First,you shouldn't talk with oher people when they are reading a book earnestly,because they have no mind to talk with you.If you take my advice,you can get our classmates recognition.
The next,you may listen to the teachers carefully,because a good student must study hard.And if you want to sudy hard,you mustn't shout loudly in the classroom.You must always finish your homework on time.You mustn't usually go to school late.And you mustn't copy our classmates' homework.
I hope you can be a good students fast.And I'm very pleased to make friends with you,Tom.
Your friends,
xxx
