     Tom was from Canada and he had come to New York for a holiday. One day he was not feeling well,

so he asked a man of his hotel to find a doctor. The man said, "Thomas Brown is a good doctor." Tom said,

"Thank you very much. Is he expensive?" "Well" the man answered, "he always asks his patients (病人) for

two dollars if they are first visit. One dollar if they are later visit." Tom decided to save one dollar, so when
