It is important for you to learn some knowledge about first aid in your daily life. If a person has an accident, he needs medical care before a doctor can be found. When you give first aid, you must pay attention to three things. First, when a person stops breathing, open his/her mouth and see if there is food at the bulk of his/her mouth. Second, if a person cannot breathe, do you best to start his/her breathing at once, using a mouth to mouth way. Third, if a person is hurt badly, try at once to stop the bleeding. Then take him/her to a doctor. If a person loses one third of his/her blood, he/she may die.

　　Many accidents may happen at home. All parents should know first aid in order to deal with common injuries which may happen to their children. When a person is bitten by an animai, wash the wound with cold running water before he/she is taken to see a doctor. When a person is burnt, wash and cool the area of the skin under the cold tap for a while. Then put a piece of dry clean cloth over the burn. If the person is badly burnt, take him/her to the doctor. If a person cuts his/her finger, clean it and put a piece of paper round the cut. Every body should know some first aid in order to save othe people's lives.

　　在日常生活中学习一些急救知识是很重要的。如果一个人出了事故，在找到医生之前他需要医疗。当你急救时，你必须注意三件事。首先，当一个人停止呼吸，打开他/她的嘴，看看是否有食物在他/她的嘴大部分。第二，如果一个人不能呼吸，你最好立即开始他/她的呼吸，用嘴对嘴的方式。第三、如果一个人受了重伤，立即止血。然后带他/她去看医生。如果一个人失去了他/她的血液的三分之一，他/她可能会死。

　　许多事故可能发生在家里。所有的父母都应该懂得急救，以应对儿童可能发生的常见伤害。当一个人被一个动物，用冷的自来水在他/她送去看医生清洗伤口。当人烧伤时，在冷水龙头下清洗和冷却皮肤区域。然后把一块干干净的布在烧伤。如果人烧伤严重，请带他去看医生。如果一个人割伤了他的手指，把它擦干净，然后在伤口周围放一张纸。每个人都应该懂得一些急救知识，为了救其他人的性命。
