【正确答案】Dear Professor,
On behalf of Beijing Teacher Training Association, I am greatly honored to have the pleasure to invite you to our academic seminar on "The Research of Western Culture", which will be held at 2:00 a.m. , Sept 15, at Room 1208, the Century Conference Center. You are requested to make a speech to our teachers at the seminar for about one hour and answer their questions.
You have distinguished yourself in the English language, as the writer of more than a dozen best-sellers on Western Culture. Your speech will surely help the teachers to enrich and update their knowledge in this field.
I really hope you will be able to attend this meeting, and am looking forward to your early confirmation of this invitation.
Sincerely Yours,
Li Ming
