Watch a video and answer the questions as follows:
What does the video show us
Have you seen this technique used before
Do you know how to do it
Do you think it’s important for us to learn
Why
What does the video show us
I think the students are learning basic first aid, in particular CPR.
=especially, particularly
心肺复苏（CPR）是对心跳、呼吸骤停的患者采取的救命技术，目的是恢复患者的自主呼吸和自主循环，包括胸外按压、开放气道、人工呼吸等一系列操作。
Have you seen this technique used before
Do you know how to do it
I have never seen CPR performed in real life, but I have often seen it performed in films and on TV. I have read about how to do it from books, you press down on the chest of a victim every few seconds. I don’t think I’m confident enough to try it myself though.
Do you think it’s important for us to learn
Why
It is important because if someone’s heart or breathing stops, they usually have 3 to 9 minutes before their brain suffers irreversible damage because of a lack of oxygen, unless CPR is performed. However, it may take anywhere from 10-20 minutes before an ambulance comes once you call an emergency service.
First Aid
If some suffered a burn, what would you do
QUESTIONS
It depends on the kind of burn. Most of the burns I’ve ever seen were fairly minor, so the best thing to do was to put it under cool running water to stop the burning.
Let’s read the passage on page 50 and learn more about first aid for burns.

First-aid treatment
Para. 1
The skin is an essential part of your body and is its largest organ. Your skin acts as a barrier against disease, toxins, and the sun’s rays. 1It also helps control your body temperature, prevents your body from losing too much water, warns you when things are too hot or cold, and gives you your sense of touch. 2As you can imagine, getting burnt can lead to very serious injuries. The first and most important step in the treatment of burns is giving first aid.
1. Your skin gives you protection from many dangerous things.

What are the causes of burns
TYPES OF BURNS
Burns are divided into three types, depending on the depth of skin damage.
First-degree burns：These affect only the top few millimetres of the skin. These burns are not serious. Examples include mild sunburn and burns caused by other minor household incidents.
Second-degree burns：These go below the top layer of the skin. They are serious and take a few weeks to get better. Examples include burns caused by hot liquids.
Third-degree burns：These affect every layer of the skin, and sometimes the tissue under it. Examples include burns caused by electric shocks, burning clothes, or petrol fires. These burns cause very severe internal injuries and the victim must go to the hospital at once.
2. A first-degree burn has this name because it is the most serious.

FIRST-AID TREATMENT
1 Place burns under cool 1running water, especially within the first ten minutes, The cool water stops the burning process and reduces the pain and swelling.
2 Dry the burnt area gently with a clean cloth.
3 Remove any clothes 2using scissors if necessary, 3unless you see the fabric sticking to the burnt skin.
4 Cover the burnt area with a loose clean cloth. Applying oil to the injured areas is a bad idea, as it will keep the heat in the wounds and may cause infection.
5 If burns are on the face, make sure the victim can still breathe.
6 If the victim is suffering from second or third-degree burns, there is an urgent need to take him/her to the hospital at once.
4. It is important to use cool water to stop the heat from remaining in the wound regardless of the degree of the burn.
5. Putting butter or oil on burns helps because it may reduce swelling and ease discomfort.

1. How are people most likely to get burnt
2. What steps can be taken to help prevent these burns
3. What other advice do you know of about first aid for burnt
Is it good advice or bad advice Why
Most people are likely to get burnt in the kitchen, by picking up a hot pan, or by getting cooking oil spilt on themselves.
Being aware of the danger is a good first step. For example, you should check to see if the burner is on before touching a pan on the stove. You should also use oven mitts when touching a hot pan. If you are using cooking oil, you should make sure that the pot is set firmly on the stove so that it cannot spill, and that it is not too full of oil.
I had an uncle who said that you should put vinegar on burns. I think that this is terrible advice, because it can cause pain and can dry out the skin.
