FIRST AID FOR BURNS The skin is an essential part of your body and is its largest organ. Your skin acts as a barrier against disease, toxins, and the sun’s rays. It also helps control your body temperature, prevents your body from losing too much water, warns you when things are too hot or cold, and gives you your sense of touch. As you can imagine, getting burnt can lead to very serious injuries. The first and most important step in the treatment of burns is giving first aid. 皮肤是人体必不可少的一部分，也是人体最大的器官。皮肤充当着一道屏障的作用，能阻挡疾病、毒素和太阳光线的侵入。皮肤还有助于控制体温，防止身体流失过多的水分，在外物过热或过冷时发出警告，并使你拥有触觉。正如你能想象的，灼伤会造成严重后果。在处理烧伤时，第一步也是最重要的一步就是采取急救措施。 be essential to/for 对…至关重要的 充当 warning n. 警告 bring about;result in;contribute to; give sb first aid/give first aid to sb 对某人进行急救 1 人体必不可少的一部分 最大的器官 充当；担当 n.光线;光束;(热、电等)射线 一道阻挡疾病屏障 毒素 太阳光线 控制体温， 阻止...做某事 触觉 烧伤 导致，造成 正如你能想象的 首先也是最重要的 急救 an essential part of body the largest organ act as ray a barrier against disease toxins the sun's rays. control body temperature prevent …from… sense of touch get burnt lead to as you can imagine the first and most important first aid first and foremost 首要的是，首先 last but not least 最后但同样重要的 The skin is an essential part of your body and is its largest organ.
