R
degree burns.
4. We shouldn’t break the blisters, or they
will make the wound infected. R

on burns to stop the infection. W
6. We should make sure the bandage won’t
stick to the skin when it is used. R

W
Ex 3 Answer the questions
1. Why should you put cold water on a
burn?
Because the cold water stops the burning
process, stops the pain and prevents or
reduces swelling(肿).
2. Why doesn’t a third degree burn
hurt?
Because in a third degree burn the
nerves have been damaged. If there are
no nerves, there is no pain.
3. Why do you think clothes and jewellery
near burns should be removed?
Because bacteria from the clothes and
jewellery could infect the burns.
4. If someone has a third degree burn,
why might you see tissue?
Because all layers of the skin have
been burnt showing the tissue
underneath.

accidentally touched the iron. Her
wrist blistered and became watery. It

was less painful. Then she went to see
the doctor.

3. Mrs Casey’s sleeve caught fire while
she was cooking . Her arm looked

covered it with a wet bandage.
