文中词汇表达比较多样,能多用学术词汇就更好了;文中如若增加一些长难句的使用,会为文章添彩;文章层次不够分明,缺少组织,需注意文章整体的组织结构。
Dear Su Qin, I am writing the letter for the purpose of expressing my apology for not having invited you to my birthday party held yesterday. You know,as one of my best pals,it is impossible for me not to give you an invitation.I did list you as one of the guests who should come to congratulate my birthday.It purely happened by chance.As I should go shopping for the party,I asked my sister to give every one of you a phone call to come.But she was not familiar to you and mistook for another person whose name was similar to yours. Please accept my heartfelt apology again.I hope to obtain your forgiveness for my carelessness. Yours sincerely, Zhang Wei
