37.What shall we do if we see someone injured in an accident?First aid is the most necessary thing we should give to him.
When we do first aid,we must pay attention to three important things.First we must make sure whether the person is still breathing.Open his mouth to check if there is any food at the back of his mouth.Then try our best to start the person's breathing within a few minutes,or he will die.Finally if we see a person bleeding badly,we must press a handkerchief(手帕) onto the bleeding point and hold it to stop the bleeding.For if a person loses one third of his blood,he may die.
First aid is also important in our daily life,for accidents may happen at home.For example,if a person is bitten by an animal,we must have him wash the wound with cold running water before going to see a doctor.When a person is burnt or cut,we should let him wash the area of his burn or cut under the cold tap and put a piece of dry clean cloth over it.But if it is serious,go to the hospital immediately for medical care.In a word,every one of us should manage to know something about first aid so we could save other people's lives.
