     One of the strangest jobs at the Oscars is that of a seat-filler. When one of the stars needs to go to the

bathroom, a seat-filler sits in the star's seat. That way, the TV cameras won't show any empty seats. Kathy

Muller talks about her night as a seat-filler.

     (A) I was told to reach the theater in the middle of the day, wearing my dress for the evening. There were

about 200 of us seat-fillers, all very excited. We were told what we should and shouldn't do (for example,

"Don't talk to the stars"), and then (B) 我们一直等到五点钟. That's when the stars started coming.

     The show started at six o'clock. We had to stand outside the doors. Then, when someone came put to go

to the bathroom or have a cigarette (香烟), we were told to go and sit in their seat. (C) The show was three

hours long, and I only sat down five times. By the end, I was really tired, but I was happy because, during

the evening, I sat behind Jim Carrey (he's very tall!) and close to Denzel Washington, Nicole Kidman and

Julia Roberts. It was an exciting night, but I think (D)_______ year I'll watch the Oscars on TV at home like

everyone else!
