　　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 father’s 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.

　　Yours faithfully,

　　Wu Ting

　　I am writing to extend my gratitude to you because with your help I am now a student of Chemistry Department of Sydney University.

　　Last June, when I applied to become a graduate student of Sydney University, you really gave me a lot of valuable help. You not only wrote a recommendation for me to Professor Wells who works in the Sydney University and also gave me careful and patient instructions on how to fill the application forms and write the application letters.

　　It is your unreserved help that enables me to obtain this splendid opportunity of further education. For the following two years I will study hard to reciprocate your sincere help and expectations with excellent grades.

　　Yours truly,

　　Zhang Ying

　　Dear Pres. Smith,

　　I am writing this letter to thank you for your warm hospitality accorded to me and my delegation during our recent visit to your company. I would also like to thank you for your interesting discussion with me which I have found very informative and useful.

　　During the entire visit, my delegation and I were overwhelmed by the enthusiasm expressed by your business representatives on cooperation with our company. I sincerely hope we could have more exchanges like this one when we would be able to continue our interesting discussion on possible ways to expand our economic and trade cooperation.

　　I feel obliged to thank you once more, and I am looking forward to your early visit to our company when I will be able to pay back some of the hospitality I received during my memorable stay in your company.

　　Faithfully yours,

　　Li Ming
