　　It would be dawn in less than an hour．For a week, Daniel Moreno, Brian Stanley, and 23 other college students from Massachusetts had been relaxing on the beach in Mexico．On their last night, Moreno and Stanley partied until 4∶00 am．But as Stanley's head hit the pillow, he heard glass shattering(破裂)．From the balcony of their fourth-floor room, Moreno and Stanley saw black smoke pouring from the hotel's tower．Almost all the hotel's rooms had college students from the United States, and now they were screaming and trying to get out．

　　Moreno, 21, ran out into the corridor and began pounding on doors and shouting, “Fire!” As the smoke thickened, Moreno raced upstairs to the rooms where other students were staying．Stanley, a volunteer firefighter in his hometown, was helping people get through the smoke-filled lobby(门厅)．There he joined forces with Nalewanski, who came from a family of four generations of firefighters．“Let's go,” Nalewanski said．He and Stanley wet their shirts in the bathroom and wrapped them around their mouth and nose so that they could breathe．Then they rushed up the stairs．

　　In the meantime, Moreno had reached the eighth floor before turning back．He made sure he hit every door．

　　Nalewanski and Stanley found Moreno on the fourth floor, struggling to breathe．After making sure he could get back down on his own, they continued upstairs, down the corridors on every floor, banging their fists on every door．

　　In the end, while a few students were treated form smoke inhalation(吸入), no one was seriously hurt．Even more incredible, all the students went back to Massachusetts later that same day．
