What is the girl doing in the picture
I think the girl is learning basic first aid, in particular CPR.
Lead-in
First aid is the first and immediate assistance given to any person suffering from either a minor or serious illness or injury.
The aim is to preserve life, prevent further harm and promote recovery.
What is “First Aid”
Have you seen the technique(CPR) used before
I have never seen CPR performed in real life, but I have often seen it performed in films and on TV, and I have read about how to do it. 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.
Pre-reading
If someone you know suffered a burn, what would you do
It depends on the kind of burn. All of the burns I’ve ever seen were fairly minor, so the best thing to do was to put it under cold running water to stop the burning.

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 (微波炉手套) 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.

FIRST AID FOR BURNS
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. It 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. As 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.

CAUSES OF BURNS
You can get burnt by a variety of things: hot liquids, steam, fire, radiation, the sun, electricity, acids, or other chemicals.
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 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 bums 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.

FIRST-AID TREATMENT
1 Place burns under cool running 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 using scissors if necessary, unless you see the fabric sticking to the burnt skin.
4 Cover the burnt area with a loose clean cloth. Applying oil on 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.
