Sammy   Armstrong   was   driving   to   his office   when   he     1    (notice)   a car was stuck on railroad tracks. Then he heard a train whistle. Sammy threw down his sunglasses and keys and ran toward the car.    2    elderly man, Jean Papich, eighty­four, sat in the driver’s seat,    3     (turn) the key and hitting the gas. His wife, Marion, seventy­eight, was looking     4    (nervous) at him. Then Sammy walked    5    the car and pushed it forward, but his boots slipped on the warm asphalt (沥青).He could see the train approaching fast.

It might be    6    (easy)to push the car backward, Sammy thought. He ran around to the front to the vehicle and shouted at Jean     7    (put)the car in neutral(空挡). Sammy could feel the ground trembling under his feet. He put his boots against the track and pushed forcefully. Finally, the car rolled off the tracks. When Sammy looked up, the train was just a couple of     8    (foot )away. Sammy, shocked and     9    (speech), went back to work as the crowd gathered at the scene.

Weeks later, Marion called to thank Sammy. He responded, “I just did     10    I had to do.”
