Model A:

Dear Johann, I must say that I agree with you．If you find something, it should belong to you because you are the person who found it．Even if I lost something, I wouldn't expect to get it back．Once I lost a ring．I decided not to look for it too much．People need to understand that when they lose something they lose the right to own it．Your letter helps me to remember that people need to be careful with their things．Then they won't need to worry about losing them．So you see, Johann, I got two rewards: one I could give to others and one I could learn from． Yours, Hu Xiaomin
