Earthquakes are one of the most destructive natural disasters. They can happen just about anywhere. Earthquakes cannot be stopped,     1     your chances of survival are much better if you know what     2     (do) when an earthquake strikes.

If you are in     3     building, drop, cover, and hold on. This     4     (be) the national standard for earthquake safety in the United States. The advice is to get next     5     a strong piece of furniture (家具) so that if a wall falls, it will create something     6     (call) the “triangle of life” to help you survive. Use your     7     (hand) and arms to protect your vital areas like your head and neck. Do not move     8     (immediate) unless it is safe to do so.

Remember that aftershocks are possible at any time and are     9     (likely) after a bigger earthquake. Take good care of     10     (you) when you leave the building.
