填空题 Most works of art are kept indoors, in a gallery, private home, office building, or museum. One category of artwork, fashioned to be on display outdoors, defies such cloistering. It is known as public art, and it is meant to be viewed easily by any passer-by. By definition, public art shapes the environment of a community. In recent decades, most supporters of public art have advocated a two-way relationship, in which the people of a community should shape public art as well.
