Dear Jack,
I am Li Hua, one of your student in China．It's a month since you left us．We all miss you and are very grateful for what you did it for us．
We are still very busy．We had the English speech contest the another day．I won the first prize, as again reminded me your great help．Do you still remember the trees we plant together on the hill behind our school? Yesterday, they went there and watered them． The tree you planted yourself is growing good, and we've decided to name it Jack Wood． Will you come back to see Jack Wood some day in the future?
We hope to know much about you and let's keep in close touch．
