Dear ______ (写你的朋友名字) How are you! Haven't been talked to you for a long time since the day I left Australia. I would like to thank you so much for spending such an amazing time with me in Australia. I have learned a great amount of new stuff since the first day i landed. When i was in China, my English was terrible. I had trouble with oral, writting and reading. But everything changed after i received your help. You taught me how to practice my English to make it better and also gave me some reading exercises to do which improved my lack of English grammar. These things will stay and be remembered in my heart forever. Today is Christmas, so i want to wish you and your families a Merry Christmas and all the best for the future. Miss you alot. Regards DaMing
