     Most people do not like to think about disasters (灾难) , so they do not prepare for them. This is a deadly

mistake. Whether you can be alive or not is decided by preparation. Here are some tips that could save your

life.

     1. Getting through the first hour 

      ● Choose an out-of-town person that each family member can call after the disaster if you become alone.

Besides, choose two nearby places where family members know to meet. One shouid be close to your home.

The other should be outside your neigh- bourhood. Keep your important papers at the bank or another safe

place. 

     ● Leave a disaster-supply kit (一套装备) ( see Part 5) near the front door. Make sure you keep it filled with

fresh food and water. 

     ● If you are advised to move to the safe place, leave the area right away.

     2. The disaster-ready home

     You may have some time to prepare before certain types of disasters. Take hurricanes (飓风) as an example. 

     ● Bring in anything that could fly around or blow away. 

     ● Prepare your car for leaving. ·Fill bottles with drinking water.

     ● Keep your radio on for weather information.

     3. The safest places 

     ● Hurricane: stay in an inside space with no windows. Class could break and hurt you. 

     ● Earthquake(地震) : get under the nearest heavy desk or table. This will protect you from falling things. 

     4. Preparing for the worst -do this now! 

     ● Hurricane:during the hurricane season, keep a two-week supply of drugs. Have wood and nails (钉子)

ready to cover windows. 

     ● Earthquake: move beds away from windows, heavy pictures or mirrors. Place large and / or heavy

objects on lower shelves. Learn how to shut off the electricity and water.

     5. Your disaster-supply kit 

    ● First-aid (急救用的) kit and drugs; spare clothes; a radio; car keys; important phone numbers.
