Making art with found materials is not a new idea. Recycled paper，cloth and metal goods can become important pictures and sculptures. Artist Allita Irby’s colorful recycled artwork was on display at a museum near Washington，D.C. She uses a material found in every American home.
Plastic bags are not costly to produce. They are also strong and easy to carry. This is why they are a popular container in much of the world. But they are also a major source of pollution. It can take hundreds of years for plastic bags to break down. As they do，tiny pieces can poison soil，lakes，rivers and oceans. So，environmental experts urge people to reuse and recycle plastic bags.
Maryland artist Allita Irby does just that. It starts with the morning newspaper. Ms. Irby will read it later in the day. What is more important is getting that plastic bag in which the paper comes. The mixed media artist recognized its rich possibilities about three years ago.“As I was taking the newspaper out，I felt the texture of these bags，and they were soft. I just looked down and realized it takes three to make a braid.” Since then，Irby has been using plastic bags to create abstract① lines in her artwork. Before incorporating plastic bags in her pieces，Irby used natural materials like feathers，leather and dried plants. All those elements represent her native American ancestry and identity，like her piece called“Navaho Bundles”.
Ms. Irby’s neighbors praise her ability to turn trash into treasure. Some，like Charlotte Hogan，asked the artist to teach them how to create art from used plastic bags.“I think it’s fascinating. I do plan to share with my seniors at my church.”Shirley Watts also lives in the neighborhood. She plans to show others her art. “I want to make a masterpiece② that I can put in a frame and put it up on my wall and then I know that I did it.”
Allita Irby says anyone can do it. “I think we’re all artists really，and there is beauty all around us.”The artist says all you have to do is open your eyes and bring the outside in.

1. Since then，Irby has been using plastic bags to create abstract lines in her artwork.
分析：本句含现在完成进行时has been using，表示“从过去到现在一直在用，并有可能持续到将来”。
2. I want to make a masterpiece that I can put in a frame and put it up on my wall and then I know that I did it.
分析：本句为并列主从复合句，主干为并列句“I want to make a masterpiece ... and put it ... and then I know ...”。第一个从句that I can put in a frame为定语从句，修饰先行词a masterpiece，第二个从句that I did it为宾语从句，作动词know的宾语。
It can take hundreds of years for plastic bags to break down.
分析：本句由it作形式主语，to break down作真正的主语，构成句型“It takes（sb.）some time to do ...”。类似的以it作形式主语的句型还有“It’s + adj./n.+ to do/doing/that ...”和“It’s said/reported ... that ...”等。
