【正确答案】[范文]April 5th, 2015
Dear Mr. Adela,
I have just got home, and I am writing to express my sincere thanks for all you have done for me while I was attending the exhibition in London.
It's so nice of you to pick me up at the airport and arrange food and accommodation for me. The food there is very delicious and the hotel is comfortable.
I have benefited a lot from the exhibition. Meanwhile, I like London very much.
I do hope you can come to China if you have time.
Thanks again.
Faithfully yours,
Linda
