     Neighbors rescued a woman from her burning home early Monday morning, and three firefighters were

hurt putting out the flames in Green Bay.

     The fire was discovered around 4 o'clock at a three-story home in the South Quincy Street on the city's

east side. Investigators say 68-year-old Mary Taylor lives there with her two dogs.

     "I got out of bed and went to the front window and could hear somebody was yelling (叫喊),'Fire!'" Curt

Dworak said. When he realized what was happening. he threw on some clothes and ran to help. "I was just

hoping Mary wasn't in there, but her car was in the driveway,so I just reacted,"he said."I just broke the glass

and then went in through the window."

      Dworak yelled for Mary but got no response. As he searched, the fire grew and debris (碎片) started

falling around him."I didn't know what to do. I yelled for her a couple more times,and then I heard her."

Disoriented (分不清方向的) and unable to move, Mary was sprawling (趴) on the floor in the back of her

house,so Dworak picked her up and carried her to safety.

     Dworak,who has been hailed as a hero by Green Bay Fire Department but shrugged of the praise,said,

"They would have done the same thing. Mary is a nice lady,and how could you live with yourself if you

out. Dworak escaped without a thin cut.
