【正确答案】正确答案： Dear Mr. and Mrs. Kruger, I would like to express my gratitude for your hospitality during my stay with you and your family. I am deeply impressed with the beauty of Sydney and the enthusiasm of Sydney people which make me feel so lucky to have visited so many places of interest and made quite a few friends while I was there. I really miss you and your children, Libby and Tom. To spend the whole day with them made me feel at home and helped me a lot with my spoken English. Also, I cannot forget your cuisine and warm conversation with you. After I got back to China, I could not help sharing the stories about my life in Sydney with my parents and friends. I would love to visit you in a year or two and hope to see you all then. Wish you all the best! Yours forever, Jimmy Brown
