A Subway Superhero

Wesley Autrey can't fly, but he is still being called a real-life Superman! Last week, the brave 50-year-old rescued Cameron Hollopeter, 20, from being hit by a train. The train was entering a subway station in New York City. The young man had fallen from the station's platform and onto the train tracks a few feet below.

Autrey, a construction worker and Navy veteran(老兵), was with his two young daughters when he saw Hollopeter fall. Autrey made a quick decision and jumped onto the tracks. He then rolled himself and Hollopeter into a gap, or opening, between the rails. Autrey used his own body to protect the young man.

Five of the train’s cars passed over the two before stopping completely. The two men were both unharmed. Hollopeter’s stepmother, Rachel Hollopeter, called Autrey an “angel”. Autrey visited the New York Film Academy student in the hospital on Wednesday.

For his bravery, Autrey was given a hero's welcome at City Hall. New York City Mayor Michael Bloomberg presented Autrey with the Bronze Medallion (铜奖章）. It is the city'’s highest award for achievements by its citizens. Mayor Bloomberg called Audrey “ a great man-a man who makes us all proud to be New Yorkers."

After the ceremony at City Hall, a limousine (豪华轿车)took Autrey to a meeting with multimillionaire businessman Donald Trump. Trump awarded Autrey with $ 10,000. The heroic father also received $ 5,000 from the New York Film Academy, a trip to Disney World, and one year of free sub way rides.

Even after all this attention; Autrey still doesn't see himself as a Superman.” I did it out of a split-second reaction," Autrey said on CBS' The Early Show. "And if I had to do it again, I probably would."
