【答案解析】[听力原文]
   M: As an artist, I'm often asked about my inspiration. Most of my work involves paper, creating dimension and filling space by folding, cutting, and positioning it. So it should not come as a surprise when I say that paper is my inspiration. Paper comes in many thicknesses, colors, textures, and sizes. I can modify and add color with paint, and destroy it with water. I can choose to use one sheet for the entire piece of art, or I can match multiple kinds of paper. But that isn't all that inspires me; I get ideas for new art from things I hear. Most mornings I spend in Central Park listening to people young and old communicate. Sometimes I go there and chat with friends. Their thoughts and ideas blossom in my mind, and when I return to my studio, I feel alive. Creating art is an internal process, but for me, what other people say and do is integral to my work.
