Dear Mr. Black,

     We're very gladly to have received your money and some reading materials. Thank you very much.

     We had been studying hard since we came  back  to school.  Under the help of  our  teacher  and

classmates, we have made great progress on our studies. So we often praised and encouraged by our

teachers and parents. We have made our minds to study hard than before to learn every subject well

in order to be admitted to key university in the future.

Best wishes!
