Dear Ge Chun,
      I haven't received a letter from you for a long time. How are you getting on with your study?
      I am very busy these days. Mnay people died or lost their homes in the earthquake. I do my best
do help the people in trouble with soldiers and doctors. Though I am tired, I feel proud of myself.
What would you do to help?
     Well, good luck with your exams!
                                                                                                                                  Yours,
                                                                                                                                  Johnson
