Dear Professor Hu,
I am very happy to have the chance to listen to your lecture on “American Literature”. But it is a pity that I was late that day due to an accident on my way to the lecture and failed to get the handout. Your lecture is really instructive for my English study, so I wonder if you could kindly e-mail the handout to the address:email@example.com@yahoo.com.cn.Heartfelt thanks.
