Talk about a real-life hero! Ten-year-old Larry Champagne from St. Louis，Missouri, hit the brake (刹车) on a runaway school bus. He saved himself and 20 other kids on board from disaster. It all happened in one terrible accident. On the way to school, the bus driver, Ernestine Blackman, suddenly fell ill. Seeing the car was running away, the other kids started to scream, but Larry ran to the front and stopped the bus. “At first I thought, ‘We’re going to die,’” says Larry, “but after I pressed the brake, I felt safe.” Larry’s speedy reaction made news all over the country. He appeared on TV shows as a hero. The bus company gave Larry a big gift. His school hung a medal of honor around his neck. “My grandmother always tells me to do what’s right,” says Larry. He thanked his brother, Jerrick, 9, who “helped me get the bus driver up” during the emergency（紧急情况）. How did he know how to stop the bus? Larry is something of a mechanic（机械师）. He helps his grandfather work on his old truck. “He gets his hands dirty,” says his grandfather. One thing is for certain: Larry knows where to find the brakes. 小题1:What did Larry do to save the runaway bus?
