The theatre did not burn down. Firefighters arrived quickly after the alarm(报警) and put out the fire so fast that no more than the seat coverings were burned. However, 602 people died, and many more were injured. Panic(惊慌), not the fire itself, caused the tragedy(悲剧).
A similar disaster occurred on a July morning in 1990 in the city of Mecca. Thousands of people were walking through a 600-yard-long tunnel(隧道) when the lights accidentally went out. Panic started the frightened people pushing their way through the tunnel and 1,426 people were killed.
The people in the Theatre and the Mecca tunnel behaved as people often do when faced with unexpected and dangerous situations such as fires, earthquakes, and floods: they panicked. Panic is one of the more extreme types of grouped people's behavior. It is a useless response to a serious threat or danger. It generally involves flight, but it is a special kind of flight. However, in panic behavior, the flight is unwise and unhelpful. It follows a loss of self-control, and it increases, rather than reduces, danger to oneself and others.

The main cause of the deaths in the fire: People's【47】not the fire itself
The length of the tunnel mentioned:【48】
Result of flight in time of danger: 1)【49】of self-control
