| Dear Alice, I have just got some good news to tell to you. I win a national prize for painting last week. My father was so pleasing that he suggested I go to England for a holiday. I’d like to staying there for half a month, visiting place of interest or practicing my English as well. We’ve been writing to each other nearly a year now. I have often dreamed of talk face to face with you. I imagine you’ll be at vacation yourself by that time. Perhaps we could go out do some sightseeing together.
