My 14-year-old brother John dreamed of having a black woolen coat, for at that time this kind of coat was 31 with teenagers, but it could cost several hundred dollars. One day my brother and I went into a shop and saw a black woolen coat at the same time. The coat felt very soft, and it cost only ＄28. It was 32 but so nice. We looked at each other, saying nothing, but John’s eyes shone. John tried on the coat and 33 it at once. John wore the coat to school the next day happily and came home with a big 34 . “How do the kids like your coat?” I asked. “They love it,” he said. I started to call him “Lord (老爷) John”. Over the next few weeks, there seemed to be a 35 in John. He became more polite, more confident and more pleasing. He would 36 his classmates his pens; he would bring his father a cup of tea when he got home; he would 37 a blind man cross the road. When my mother talked about her son’s change with one of his teachers and wondered what caused it, he said, “It must be his 38 !” One day, in the library, my brother and I happened to meet a friend of my father’s, who had not seen us for a long time. John came up and shook hands with him like a 39 ! The friend said in surprise, “Are you John? You have changed so much!” What really changed John was his own attitude(态度). 40 you think you are a gentleman or a lady, you can become a perfect one.
