　　(2015·长春市质量检测二)

　　A great number of people can get injured or even killed resulting from a human stampede (踩踏)．The bad thing is that a peaceful group of people can quickly turn into a crazy panicked crowd. __1__

　　If you are in a crowd, the most important thing is to make yourself familiar with your surroundings and mentally notice the exits. No matter where you are make sure you always know how to get out. __2__ If you are in a crowd of moving people, wet or uneven ground can be slippery or dangerous, causing you to fall.

　　Be aware of the general atmosphere of the event, as panic situations can often be expected. When in danger, a few seconds can make all the difference. If you find yourself in the middle of a moving crowd, do not fight against the pressure, do not stand still or sit down. __3__
