Question

   Emergencies (緊急情況) don't happen very often. But when they do,you want to get help first. No one wants to spend time looking up the phone numbers.

    In 1967,the United States government wanted one number that people could call for emergencies. They decided that 911 was easy to remember and people could dial it quickly. The very first 911 call was made on February 16 ,1968,in Alabama. Today,911 is used for emergencies in most parts of the United States and many parts of Canada.

   Other countries may use other numbers. In Great Britain,it's 999. If you’re not sure which emergency number is used in your area,check your phone book.

   When to call

   Never call 911 as a joke or just to see what might happen. The only time you should call 911 is when a person is badly hurt or in danger right now!So call when there is a fire,a car accident,or sudden sickness,etc.

   When in an emergency call 

   When you dial 911,it's always OK to give out your information. Speak slowly and clearly when you explain what's happening. What happened? Where are you? Who needs help?

   Don’t hang up (掛斷) ！

If you have to call 911,do not hang up until the operator (接線員) tells you it's OK to do so. That way,you can be sure that the operator has all the information to offer help fast.
