Dear Helen,
     Thank you so much for your party at Christmas Eve. All
of them enjoyed it very much. We liked the dishes you had
cooked but we were happy to learn the English songs you taught
us. We hope you'll teach us a lot many songs in the future.
     We're leaving from our hometowns to spend the winter
vacations. It seems that many of us are homesick after
being away from home for such the long time. What are your
plans? Will you join in the tourist group organized by our school? 
      We are busy prepare for our trips. Please excuse us
for not able to say goodbye to you.
     We hope you'll have a good time.
                                                                      Yours,
                                                                     Xiao Hua
