Unit 5 first aid Reading学案
FIRST AID① FOR BURNS
The skin② is an essential③ part of your body and its largest organ④. You have three layers⑤ of skin which act as⑥ a barrier⑦ against disease, poisons⑧ and the sun's harmful rays⑨. The functions⑩ of your skin are also very complex⑪: it keeps you warm or cool⑫; it prevents your body from losing⑬ too much water; it is where you feel cold, heat or pain⑭ and it gives you your sense of touch⑮. So as you can imagine, if your skin gets burned it can be very serious. First aid is a very important first step in the treatment⑯ of burns.
Causes of burns
You can get burned by a variety⑰ of things: hot liquids⑱, steam, fire, radiation⑲ (by being close to high heat or fire, etc), the sun, electricity or chemicals.
