“我的成绩单“的英语作文

Dear Martin
This is Percy ,today I got my school report card for final term exam.I was very nervous when I saw my English report.It was discouraging.I want very much to learn English well, but I don't know how to do it. My problem is that the textbook Go For It is too difficult for me.There are so many words and expressions to remember.Sometimes I can say them,but I forget how to spell them when I write them.I am a litte better at speaking and listening than at reading.Sometimes when I do my homework I just copy other students' answers .Could you please give me some advice on how to improve my English? I really need your help.
Thank you very much.Please write to me soon. I am looking forward to it
Yours ,
Percy
