【正确答案】 Dear Mary,
I' ve come back home safely. Looking back on my stay in Britain, I feel so happy and satisfied. The beautiful scenery and friendly people impressed me a lot. I also benefited a lot from learning together with local students. More importantly, your help and kindness made it easier for me to have a better understanding of British culture and adapt to the life there. So I' m so grateful to you.
By the way, attached to the letter are two photos taken with you, which I believe will remind you of the happy time we spent together. Would you like to make a trip to China? If so, please let me know as soon as possible. I can't wait to meet you soon and show you around the places of interest. I' m sure you won't regret it.
Looking forward to your reply.
Yours sincerely,
Li Hua
