阅读理解。 Mr. Andrews was waiting for a subway train in the city. The train pulled into the station and stopped. As Andrews was getting ready to board the train, he saw an elderly blind man fall to the tracks (站台). David Schnair, aged 75, had mistaken the space between two subway cars for a door, while feeling his way with a cane. Instead of ending up inside the train, Schnair fell off the platform and landed under the train. Andrews jumped down to the tracks to save Schnair. He pulled the man to safety. Onlookers immediately declared Andrews a hero. Messages began to pour in from all over the country. Some people sent checks. The largest was for $3,000. President called Andrews and wished him a Merry Christmas and a good new year. Andrews had been on the subway because he was returning from a job interview. He probably would have been hired anyway, but all the good publicity () made it a sure thing. After about a week of newspaper stories and donations of food, money and gifts for his children, Andrews faded from limelight . Most people assumed that the story had come to a happy ending, but it didn't quite happen that way. Andrews did start his new job, but the company moved to New Jersey.
