There is only one number in America to call for all emergencies, 911. When you call 911, you are asked if you need the police, the fire department, or an ambulance. For health emergencies, an ambulance is sent to your location and takes you to the hospital's emergency room. At the emergency room, a nurse checks on your injury and assigns you a place in line to see the doctor. If you are truly dying, you will see the doctor right away. If you have a cut or a broken arm, you may need to wait. In this way, the doctors are able to try to help the people who most need help. It is important to remember this and try to patient.

在美国遇到紧急事件，911是唯一可拨的电话号码。当你拨911后，电话里会有人问你是要找警察、消防队还是需要急救车。要是事关医疗紧急状况，急救车便会派往你所在的地址并且把你带去急救室。在急救室，护士检查你的伤势并按顺序安排你看医生。如果病人接近死亡的话，医生便会马上赶来。如果只是被切伤或手臂摔伤，则需要等候。这样，医生才尽可能帮助最需要帮助的人。牢记这点非常重要，而且要切记耐心。
