Before long, I joined the activity of CPR in school.  The activity is held continuely

two days.  I learned how to bandage when getting a hurt, no matter in  head, arms, or

feet.  We all taught.  Although I didn't do very well on the test day, I still learned a

lot, such as the sign of first-aid is 叫叫ABCD, the first 叫 is "estimate sense."  It

means we need estimate the patient's sense when the accdient happed.  The

second  step is "call for help."  We need to call for someone to dial 119.  Remember,

You must call over two people becuse it can at least two people prove you in the first

scene.   Then, A means "Airway," B means "Breathing", C means "Circulation", D

means "Defibrillation."  I think learning first-aid skills and theory can not only increase

help common sense but also be used in the emergency condition to help patients. 

After all, help elder, weaker, women who carry babies, or anyone who need help, we

all feel happy.  So, First-aid is essential and useful in life.
