Dear Mir./Mis XXX,
the winter holiday have past for a half month, and we have not met you for a few days. All the student are missing you, me too. how is your winter holiday?
I had a very happy Spring Festival,and this was my happiest time in my life. We played fireworks and watched new year's party during the Spring Festival.
I had done as you told us. I studied English every day. And now I have remembered many words. I also can speak some of simple english. I thanked for your suggestion.
Today is the third day of new year, I bless you happy new year, and everything goes well.
yours sicerely,
XXX
