附加题（阅读理解）。

     Most young architects-particularly those in big cities-can only dream about working in a building of their

own. And making that dream come true often means finding a building no one else seems to want, which is

exactly what happened to David Yocum and his partner, Brain Bell. Their building is a former automobile

electrical-parts film in Atlanta. Form the outside, it looks too old, even something horrible, but open the door

and you are in a wide, open courtyard, lined on three sides with rusting (生锈的) walls.

     In 2000, Yocum and Bell found this building in the city's West End. Built in 1947, the structure had been

abandoned years earlier and the roof of the main building had fallen down. But the price was right, so Yocum

bought it. He spent eight months of his off-hours on demolition (排除), pulling rubbish out through the roof,

because it was too dangerous to go inside the building. The demolition was hard work, but it gave him time to

think about what he wanted to do, and "to treasure what was there- the walls, the rust, and the light." Yocum

said. "Every season, more paint falls off the walls and more rust develops. It's like an art installation (装置) in

there-a slow-motion show."

     Since the back building had been constructed without windows, an all-glass front was added to the building

to give it a view of the courtyard, and skylights were installed in the roof. The back of the building is a working

area and a living room for Yocum and his wife. A sort of buffer (缓冲) zone between the front and the back

contains a bathroom, a kitchen and a mechanical room, and the walls that separate these zones have openings

that allow views through to the front of the studio and the courtyard beyond.

     Yocum and Bell, who have just completed an art gallery for the city, feel that the experience from the

decoration of their building, focusing on the inside rather than the outside, has influenced their work. It has

also given these architects a chance to show how they can make more out of less.
