21. Post-reading
Answer the questions in your own words according to the passage.

burn?
2. Why doesn’t a third degree burn hurt?
Because the cold water stops the burning
process, stops the pain and prevents or
reduces swelling（肿）.
Because in a third degree burn the
nerves have been damaged. If there are
no nerves, there is no pain.

near burns should be removed?
4. If someone has a third degree burn,
why might you see tissue?
Because bacteria from the clothes and
jewellery could infect the burns.

been burnt showing the tissue underneath.
