During my visit to China, I stayed in several hotels. I would like to say something about fire regulations(条例) in these hotels. When I was in Beijing in a hotel, I checked the nearest fire escape to my room, as I usually do, I found that the exit(出口) out of the buildings was on the ground floor, chained and locked! If there was a fire, people wouldn’t be able to escape. In some other places, I did not find any notice about the procedures. In most hotels in my country, there is a notice on the back of the door of every guestroom. In Japan the porter（门卫）actually points out the 21、1912年，孙中山辞去临时大总统表示将致力于“社会革命”，这里的社会革命是指（  ）        A．实现民生主义               B．实现民权主义        C．实现社会主义               D．实行三大政策
