Dear Sir,
I`m so sorry that I can`t go to attend the CHinese Culture lacture,so I ask you for leave.
I know this English lecture is very important for me to learn Chinese Culture.I am also eager to go there very much,because this is a best opportunity to learn more knowledges about Chinese culture.It will help me to improve Chinese.But I have had a bad cold for 3 days.So I am afraid that I can`t go to attend the lecture tomorrow morning.
I wonder if it is possible that your lecture will be recorded,can I borrow one to fix up this lecture?
I am really soory for not being able to listen the lecture.I hope you can allow me to ask for leave and I wish you`ll excuse me.
yours,
