問題詳情：
Hello, boys and girls! Today, I am going to talk with what you should do when a fire alarm go off. If you hear the alarm, stand in line at the door and wait your teacher to lead you outside. Stay close to your teacher and classmate. Don't panic or get out of line, and trying to remain quiet and calmly. Soon the firefighters will come and put out a fire. If it's a false alarm and there is no fire, your teacher will lead us back to the classroom. If you notice that when someone is missing and hurt, tell your teacher immediately.
