Dear Mr. Brown，
I am writing to express my deepest gratitude for the money and books you sent me. I could not have returned to school without your help. Thank you so much.
I have been working hard since I went back to school. I have made great progress in my studies with the help of my teachers. They often praise me and encourage me. But for your help, I might have left school and couldnt have got such a good education. I have made up my mind to study harder and make greater progress.
How are you getting on with your life and work? I would like to meet you in person, but I have no opportunity to do so. Would you please send me a photo of yourself? Thank you again for your generous help and best wishes!
Yours Sincerely, Li Hua
Dear Mr. Rogers,
It is my great pleasure to show my hearty thanks to you for your hospitality and courtesy to me during my stay in London.
Originally I only wanted to call on you and gave my fathers regards to you, as it had been three years since you and he last saw each other. But you insisted that I stay in your house during my visit in London and took good care of my life as if I were a family member of you instead of the daughter of one of your friends. You really added greatly to my convenience and pleasure of the whole trip.
Thank you again for your kindness and I hope that I will have the opportunity to return your charming hospitality.
Im writing the letter for the purpose of conveying my thanks for your warm reception [during my recent visit to your country].
Your friendly warmth made it possible that I have a pleasant time in America. And it was your generous help that allowed me the chance to know the American culture better. In addition, I consider in an honor for me to make a friends of you. I hope that you would visit our country in due course so that I could enjoy the opportunity to repay your kindness and refresh our friendship. Please accept my sincere thanks. Wish you all the best.
