First Aid
    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.

急救方法
    在日常生活中，学习一些急救知识，对一个人来说很重要。假如一个人发生车祸，在医生到来之前，需要对他进行医疗护理，做急救时，应注意以下二点。首先，如果他停止了呼吸，掰开他的嘴巴看看喉咙口有无食物。其次，假如他不能呼吸，就采取人工呼吸的方法，尽快使他开始呼吸。再其次，如果他伤的很重，应立即止血，然后送往医院。如果他失血过多，达三分之一，那么他有可能会死。
    许多意外事件也有可能在家里发生。因此，家长们应掌握一些急救常识，以便应付一些发生在孩子身上的事件。假如孩子被动物咬伤，先用自来水冲洗伤口，然后送去看医生。如果孩子被烫伤，先用自来水冲洗，降温，然后用一块干净的干布盖住伤口。假如烫伤很严重，应去看医生。如果割伤了手指，应先将伤口处理干净，然后用一块纸包扎伤口。人人都应学习急救知识，这样才能救其他人的性命。
