Dear_Ms_Kate,

     I'm_Li_Hua._Four_years_ago,_I_received_your_letter_and_schooling_fees. I'm very grateful for your kindness and generosity.

     But for your help, I couldn't enjoy a wonderful college life in the beautiful campus right now. I've made a lot of friends here. Moreover, I am studying hard so as to acquire an abundant knowledge of English,

which is my major. In fact, I'm making progress each day. Only in this way can I learn more and use what I've known to help those in need as well. Besides, I'm determined to go back to my hometown after

graduation and devote myself to building my hometown, to make it more prosperous and beautiful.

     Words seem to fail me when I try once more to express my thanks to you, and I'll keep my promise

and not let you down.

                                                                                                                            Yours_sincerely,

                                                                                                                                     Li_Hua
