Dear XXX

It's so kind and thoughtful of you to buy me this dictionary. I really like it and it gives me a great help when I deal with the new words! I will cherish it and play its great value.
Here I thanks you again! In return, what about coming to my home and have a dinner this weekend with my family.

Dear XXX ,
Thanks so much for your great gift. I know that you gave a dictionary to me because you would like to encourage me. This present will be very helpful to my studies in the future. It is not only convenient but also very useful. I can memorize new vocabulary with it or look up difficult words. I think it is very important for me to have a dictionary as a learner of a foreign language. And this pocket dictionary you gave to me is a perfect one to carry around wherever I go, and it will help me to learn new things. Thank you again for your kindness. I hope you can make progress in your studies, too!e799bee5baa6e997aee7ad94e4b893e5b19e334
