Dear Katherine,
How exciting I am to hear you are coming to visit me the next Friday．Fortunately, I won' t be able to meet you at the airport although I have classes in the afternoon．You won' t find difficult to get to the city center．The airport bus left every 30 minute and will take you right to the International Hotel．My class will be over by then or I will pick you up there．I will take you to a hot-pot restaurant for dinner and we' 11 talk with our plan for the weekend over dinner．Having a pleasant trip and see you on Friday．
Sincerely yours
Zhang Lin
