【正确答案】正确答案：Dear Lucy, I am writing to apologize to you for not handing in my homework in time. With Teachers' Day approaching, I have to be faced with so many extra preparations to make for the celebration of Teachers' Day. Yesterday was the busiest time, some students and I had to spend hours in designing, decorating, arranging the stage and getting ready for the necessities for the celebration, leaving our homework unfinished. I am sorry for what I should have done. I will make up for the missed homework as soon as possible. By the way, will it be all right if I hand in my homework tomorrow morning? Looking forward to your reply soon. Yours sincerely, Li Hua
