20．My 14-year-old brother John and I saw the coat at the same time．The thick black woolen coat was soft，and it cost only﹩28．We looked at each other，saying n（73）othing，but John's face was shining with joy．Dark woolen coats were p（74）opularwith boys just then，and could cost several hundred dollars．But this coat was even better and much cheaper．
John t（75）riedon the coat and bought it at once．John wore the coat to school the next day and came home with a big smile．"How did the kids like your coat？"I asked．"They loved it，"he said．I started c（76）allinghim"Lord （老爺） John"．
A few weeks later，something good h（77）appenedto John．He became more polite，more helpful and more pleasing．He was willing（愿意） to lend his classmates his pens； he was willing to bring his father a cup of tea when he got home； he was willing to help a blind man c（78）rossthe road．
When my mother told this to one of his teachers，he said，"It must be his coat!"One day，in the library，my brother and I ran into a friend．"Could this be John？"he asked．John shook hands with him，l（79）ikea gentleman（紳士）!
I think John changed b（80）ecauseof his own attitude（態(tài)度）．If you think you are a gentleman or a lady，you can become a perfect one．
