填空题

Dear Mr. William Wilson,
Thank you very much for accepting my arrangement of an interview about your travel to China.
I am expecting your return from China and hope to see you the following week after your return. I set 2 pm to 5 pm on Monday or Tuesday for your decision. I will wait for you at the south entrance of the university library at 2 o’clock pm on the date you will decide. The interview will be held at the editor’s office of our University Journal.
I would like to know why you went on trip to China and I am interested in your general description of the tour and the points of interest. I hope you will bring your own photographs of places you visited or some other things that concern your trip to China. I plan to arrange some photographs of the interview beside a magazine article. I think the interview will bring our readers something very interesting.
I am looking forward to meeting you soon.
Yours sincerely,
Alan Newton, editor
NYU Journal
