Period 2 Reading, Comprehending
Teaching Goals: 1. To develop Ss’ reading ability.
2.To learn something about dealing with burns practically.
Teaching Procedures:
Step 1. Skimming
Purpose: To get a brief understanding of the text.
1. Ask Ss to read the title of the text and the headings in it and then ask them:
(1) What is the topic of the text?
(2) How is the information organized?
(3) How is the information organized within the heading of “types of burns and characteristics of burns”?
(4) Why is the information under the heading of “First Aid Treatment” numbered?
Suggested Answers:
(1) It’s about first aid for burns.
(2) The information is organized according to causes, types, characteristics and first aid treatment for burns
(3) The information is organized according to the types of burns: first degree, second degree and third degree burns.
(4) The numbers indicate the steps you should take to treat a burn, in the order that they should happen.
2. In which order are these topics in the text? Number them from 1 to 5.
( ) the three types of burns.
( ) what to do if someone gets burned.
( ) the purpose of skin.
( ) the symptoms of burns
( ) how we get burns
Suggested Answers:
Right order: 3. 5. 1. 4. 2.
Step 2. Scanning
Purpose: To get Ss to have some details in the text.
Read the first aid treatments for those burns. Write R (right) or W (wrong) in the bracket. Then correct the wrong treatments.
(1) Sam knocked over a kettle full of boiling water onto his legs. His legs became red, swollen and covered with blisters. Sam broke the blisters and poured icy water from the fridge onto the skin.( )
(2) While ironing clothes, Miss Good accidentally touched the iron. Her wrist blistered and became watery. It hurt a lot. She put her wrist under the cold water tap and then kept placing cool, clean , damp clothes on it until it was less painful. Then she went to see the doctor.( )
(3) Mrs. Casey' sleeve caught fire while she was cooking. Her arm looked terrible but it didn't hurt. The skin was charred. 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. ( )
(4) After an hour in the sun, Lily noticed her arms were red and hurt a bit. She went home and put them under cool running water. ( )
Suggested Answers:
(1) (W) Sam shouldn't have broken the blisters because the burns could become infected. He should have poured cool water, not icy water on the burn .The correct treatment for a second degree burn like Sam's is described in the text.
(2) (R)
(3) (W) Mr. Casey was right to take his wife's blouse off but he should not have picked bits of blouse off the burn. This is because if you pull material that is stuck off a third degree burn like Mr. Casey's, you would pull the tissue under the material off too. This would cause more damage to the burn. He should not have put butter on the burn because it would have stopped the heat from escaping and it might also cause the burn to become infected. He should not have put a wet bandage on the burn. The correct first aid treatment for a third degree burn is to remove clothing and jewellery near the burn but not if the clothing is stuck to the burn. Do not put cold water on the burn. Place clean, dry clothes over the damaged area. Get the person to a hospital at once.
(4) (R)

A.110 B.114 C.120 D.119
Suggested Answers:
(1) C Gao Yuan is in greater danger of dying than the others because he is not breathing .He needs rescue breathing to start his breathing again.
(2) A The easiest place to check for a pulse is on either of the carotid arteries, which run down both sides of the neck.
(3) C
(4) A Before doing anything else, you need to make sure that the airway is open by clearing away anything in the mouth. If you checked to see if the person were breathing first, you might be extending the time that the person isn’t breathing. This would endanger his/her life to a greater extent than if you checked the airway straight away.
(5) B Third-degree burns are the most serious because all three layers of skin have been burnt.
(6) D You need to stop the burning process and the pain and reduce the swelling before taking her to the doctor. To do this, you would put her fingers under cool running water.
(7) D If you don't do anything, the person could bleed to death .You need to put a bandage on the wound and apply pressure to reduce the bleeding. Applying pressure is important. Plastic would not absorb the blood. You cannot wash the wound before the bleeding stops.
(8) A If she can cough or speak or breathe, you shouldn't do anything. If you slapped her on her back you could cause the piece of food to move and completely block the airway. You would slap her between the shoulder blades if she couldn't cough (or speak or breathe)and was turning blue in the face. This might cause the piece of food to move and unblock the airway, or it might make her cough the piece of food out.
(9) B To stop the bleeding she should sit down, bend her head forward slightly and gently pinch the soft part of the nose below the bridge. If she bent her head backwards, the blood would run down her throat and possibly make her sick.
(10) D It’s important for the victim to sit down, keep his foot up, for example, on another chair, and have an ice pack on his ankle to reduce the swelling. He mustn't use his foot. It’s good idea to then put a firm bandage around the foot and ankle. Warm cloths could be put on the ankle only after the first 24 hours.
(11) C 120 is the emergency phone number for the ambulance; 110 for police station; and 119 for fire station.
