【答案解析】Dear Personnel Manager,
I am writing this letter to tell you that I will resign from editorial department.
It has been a great pleasure to work with you in the past two months. But my current position as an editor doesn"t quite suit to my personal interest and career plan. As I majored in finance in college, I really want to work in the business field.
I sincerely hope that you could accept my resignation and apology and thank you very much for all your help in the past two months.
I am sorry for any inconvenience caused.
Yours faithfully,
Li Ming
