假定你是李华。请你给美国的朋友Tom写封信，告诉他你将去他所在的城市度假，带去他想要的那幅中国丝绸，同时询问他是否可以接机。信中还需要说明：
航班号：CA991
到达：8月16日上午11:30
注意：1.词数100左右；
2.可以适当增加细节，以使行文连贯；
3.开头语和结束语已为你写好。
Dear Tom,
How are you doing?
                                                                               
                                                                               
                                                                               
                                                                               
                                                                               
                                                                               
                                                                               
Looking forward to your reply.
