【答案】Dear Miss White，
I'm Li Hua， deeply sorry for not being able to attend your lecture about English history next Monday afternoon. I'm writing to ask for a leave.
I am to participate in my final-round English Speech Contest on the same day， for which I have prepared for a long time. Personally， I'm desperate to achieve a preferable result. There is no doubt that the lecture about English history interests me most and I will try hard to make up. Would it be possible for me to have my classmates take notes for my later use.
Hoping to have your permission.
Yours Sincerely，
Li Hua
