Dear Mr. Miller and Mrs. Miller.,
Before we leave Australia, we would like to write this letter to you. We enjoyed the seven days' visit with your help. When we arrived in Australia, you welcomed us. Then you took us to travel around and we visited many beautiful places. You also cooked delicious food for us at home. We had a good time here. Thank you for all the help.
Here is a gift for you, a kite from China. The red color is the symbol of good luck. We hope you will like it.
