Review
Situation 1 Mrs King’ s sleeve caught fire while she was cooking. Her arm looked terrible but it didn’t hurt. The skin was charred.
Situation 3 While ironing clothes, Miss White accidentally touched the iron. Her wrist blistered and became watery.
It hurt a lot.
Situation 2 After an hour in the sun, Lily noticed her arms were red and hurt a bit
Treatment :Her husband took off her blouse and picked off bits of the blouse stuck to the burn. He then placed butter on the burn and covered it with a wet bandage.
Treatment: She put her wrist under the cold water tap, and then placing cool, clean, damp clothes on it until it was less painful. Then she went to see the doctor.
Treatment: She went home and put them under running water.
third degree burns
Right
Wrong!you would pull the tissue under clothes off too. This would cause more damage to the burn.
wrong!it would prevent the heat from escaping and cause infection.
first degree burns
Right!she did right. Putting the sunned arms under running water can stop the burning process, prevent the pain becoming unbearable and reduce swelling.
second degree burns
Right!if the burns are second or third degree burns, it is vital to get the victim to the doctor or hospital at once.

Good evening everyone,
I’ m really honoured to have a chance to be here to make a speech.
As we all know, in our daily life, getting burnt is very common, which may be caused by various things, such as radiation, hot liquids, steam and electricity or other chemicals. There are three types of burns, including first degree burns, second degree burns and third degree burns. Each of them has its own characteristics. For example, if your skin turn white when pressed, you get first degree burns. If your skin have blisters, watery surface, you get second degree burns. If your skin become black and white and sometimes the tissue underneath can be seen, it is likely that you get third degree burns. Once you get burns, don’t be too panic and try six- step first aid treatment. Place burns under cool running water. Dry the burnt area with a clean cloth. Remove any clothes, but keep it in mind that never touch the fabric sticking to the burnt area. Cover the burnt area with a loose clean cloth. And make sure the victim can breathe. Lastly, if the burns are very serious, it is necessary to send the victim to the hospital immediately.
Being the largest organ, our skin is very important to our body. We’d better protect it and learn some first aid treatment. Of course, if you can avoid getting burnt, it would be wise. Wish you good health.
1. Polish your speech by adding more information. Then share it with your classmates and make a feedback.
2. Surf the Internet and find out the first aid treatment for other urgent situations, such as choke, snake bite, a sprained ankle.
