     Since 1984, Philadelphia has been cleaning up its act.One by one, graffiticovered walls

are being changed into outdoor art.So far, more than 1,800 murals (壁画) have been

painted.Philadelphia now has more murals than any other American city.

     The walls that were once ugly with graffiti (涂鸦) are now covered with beautiful pictures

of historical heroes and modern art, thanks to the Mural Arts Program (MAP).Its work

makes schools and public places attractive, and its citizens very proud.The program began

as part of Philadelphia's AntiGraffiti Network.Jane Golden is the MAP's artistic director."

When people ask me what our program is about," she says, "I answer them with one word:

hope." Each year, the MAP offers youth art programs and workshops.Some onetime

graffiti writers even help paint MAP murals.

     The MAP's work, says Golden, is all about developing a sense of community (社区).

When a neighborhood requests a mural, the MAP works with the people there to develop

a message.Some messages have been "Safe Streets","Love and Care" and "Peace Walk"

     The MAP receives up to 50 requests for murals each week.Last year, the workers

painted 140 murals.

     "The making of a mural enters people's collective memory as an extraordinary, pleasant

moment in neighborhood history." says Golden, who began as a muralist in Los Angeles.
