Most people don't take first aid(急救)training because they are busy. Some even think only doctors need to learn first aid. But in fact, it is useful. Here are the good sides of learning first aid.
First aid helps save lives. Giving someone first aid can help him or her get better fast. First aid training teaches how to keep calm in emergencies (紧急状况下).
Help someone feel better. Not every accident or injury(受伤) needs a visit to the hospital. But it doesn't mean you should not try to help someone injured, even though the injury isn't very serious. You can use first aid to help anyone in need, for example, a person who doesn't feel well because of a fever.
Keep a situation from getting worse. Sometimes, if a person doesn't get first aid in time, his or her situation will get worse soon. If you give him or her simple care, you will help him or her feel better and keep things from getting worse.
