Answer 1

Dear Sir，
    I'm so grateful for your good service during my stay in Beijing for a tour，but I'm writing to ask a favour to find and send back my pack which I left in your hotel．（高分句型一）
    I checked in on Oct.2 and out on Oct.6．Setting off in a rush for the station，I left the pack in Room 702．It's a medium-sized，blue，leather backpack which contains some reference books，a white ipad，a credit card and some cash．All in the pack matters to me，especially the ipad，a precious gift from my father on my 18^th birthday．So much did I cherish it that I feel upset for its loss．（高分句型二）
    If you find it，would you please post it to me？The return address is at the end of the letter．
    I'll appreciate it very much if you can give me your earliest reply．（高分句型三）
                                                                                                                                                         Yours sincerely，
                                                                                                                                                            Li Jin
