Dear Lucy,
I was delighting to receive your letter. Thank you for the English dictionary you bought it for me. I received it this morning. There is no doubt that it is of great helpful to me. I'm deeply grateful for your advice what I should pay more attention to practise my spoken English. I've made up my mind to speak English both in and out of class. Next month I'll take trip to Australia, which is organizing by my school. I hope I can practise my spoken English there as many as possible. By the way, I am sending you a set of stamp with this letter, and I'll send you more if I got any. I do hope you will have a good holiday.
Yours,
Li Hua
