19. As I walked along the sidewalk in front of Surplus Unlimited,a car that was about to change my life had just turned onto Route 82 from the CVS parking lot.I looked up and noticed the elderly couple in the car heading toward me.As the car rolled past,the driver suddenly collapsed against the steering wheel(方向盘) right in front of my eyes.His wife stared blankly out of the passenger side window.She was unaware that her car was now rolling—without a conscious driver—down the center of a busy road. I began to jog alongside the moving car.My mind assessed the situation,Somebody needed to stop that car! I reached forward,but there was nothing to grab.I pounded on her window.She looked confused,"Roll down the window!"I yelled,gesturing wildly.With the window down,I was able to grab the doorframe,I pulled hard against the force of the moving vehicle.On the far side of the car,the traffic streamed by in the opposite direction,Cars passed one after another,Nobody slowed down.Nobody seemed to notice. Thankfully,the driver's foot must have slipped off the gas pedal(踏板) when he lost consciousness.I kept pulling,and the car began to slow. Just then,a woman appeared from behind me.She ran alongside the driver side door.She opened the door and as the car was slowing,she managed to shift it out of"Drive".A joyful"We did it!"feeling swept over me. But the car was now stopped in the center lane(车道) with traffic still moving in both directions around us and we need to help this man.Quickly!The woman called 911 while I checked his vital signs.He was not breathing.He had no pulse.He had about five minutes until he was dead.CPR was needed in no time. 注意: 1.续写词数应为150左右: 2.请按如下格式在答题卡的相应位置作答。 Thoughts started running through my mind.___________ In an instant,the man from the black SUV was standing beside me and said,"I am a doctor."________
