线话英语口试话题：急救（First aid）

 First aid is the aid or help that is given to an injured person or a patient first before any other help arrives. I think that everybody should have some first aid knowledge, because it is very important in medical emergencies.For example, if a man hurt his body, the first thing he should know is whether he get hurt seriously or not. If it is not serious, he can do the first aid himself, and if it is serious, he have to call 120 or 999 as quickly as he can. In a word, we should learn to the first aid.
