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(调查者) 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 didn't do something like that?”

Miss Gorgers taught physics in a New York school. Last month she explained to one of her classes about sound, and she decided to test them to see how successful she had been in her explanation. She said to them, “Now I have a brother in Los Angeles. If I was calling him on the phone and at the same time you were 75 feet away, listening to me from the street, which of you would hear what I said earlier, my brother or you and for what reason?”
