Dear Ms Smith,

I am Li Hua. I am writing to ask for a several-hour leave. I was to give a speech to welcome a group of American visiting teachers on Wednesday morning. I am terrible sorry to tell you that I can't come to attend at your class. How a pity! Perspectives on American Literature are always my favourite course. I do hope you can excuse my absent. As to the lessons to be missing, I wonder if it is possible for them to recorded so that I can listen to them later. Or I will just read my classmate's notes and making them up as soon as possible.

Your permission will be appreciated. Thank a lot !

Yours,

Li Hua
