Now doctors say a bystander can recognize a stroke by asking three simple questions:
1. *Ask the individual to SMILE. （微笑）
2. *Ask him or her to RAISE BOTH ARMS. （举手）
3. *Ask the person to SAY A SIMPLE SENTENCE (Coherently) (example: "It
is sunny today") （简单的词句如今天的天气真好）
If he or she has trouble with any of these tasks, call 救伤车
