A letter to friend. Russia 01.10.2014 Dear Andy, I was very happy to get your letter.Sorry,I haven't written for so long because I have been busy at school. You asked me about study at school.In my opinion,you should understand that marks aren't your knowledge.Just continue to do all your homework and be interest in your school subjects.Yes,I think you should talk to your parents and explain how you feel.They can help you.As for me,I study well,but not exellent. Andy,how much time you do your homework?Do you have a hobby?How long it takes? Well,that is all for now.Write back soon. With best wishes, Effy.
