Dear Mr. Green and Mrs. Green,
I am writing to express my thanks to your warm hospitality.
I am a perfect stranger when I arrived in America for my study abroad. My English was poor and I know only a little of America. So I am quite worried about my stay. But when I found I would live in your family, I became a lucky dog. Your are so kind and treat me like your own daughter. Mr.Green taught me a lot of knowledge about America, and Mrs. Gree cooked delicious American food. During these days, My English ability improved fast.
Now, I'm back in China, but I still miss you so much. I look forward to your coming to China.
yours,
Ann
