　　dear liu dong,

　　i'm back at school now. i wish to express my thanks to you for the wonderful vacation i spent with you and your family. during the vacation you taught me how to swim, boat and fish. i really appreciate① your taking time off work to take② me around and show me so many places.

　　your mother is such a terrific③ cook! i think i must have gained 10 pounds just in the week i spent with you. surely i've spent a happy vacation, which will be remembered for long.

　　i hope you will be able to visit our school sometime. thank you again. let's keep in touch.

　　love,

　　li ming
