1 . First aid is a crucial aspect of healthcare that can significantly save someone’s life or prevent further injury or illness. Knowing when to use first aid is essential so that proper measures are taken promptly.
Injuries and Accidents
One of the most common instances where first aid is required is in injuries and accidents.
Cardiac Arrest (心脏停跳)
Another critical situation where first aid can make a difference is during a cardiac arrest. A cardiac arrest occurs when the heart stops functioning; immediate intervention is necessary.
Choking and Suffocation (窒息)
Choking and suffocation are emergencies that can occur at any time, and immediate intervention is necessary to prevent further complications. If someone is choking, it is essential to act quickly.

2 . Any car accident is frightening, but an accident in which your vehicle is thrown into the water, with you trapped inside, is absolutely terrifying.
Brace yourself for impact (撞击力). As soon as you're aware that you're going off the road and into a body of water, adopt a brace position. The impact could set off the airbag system in your vehicle, so you should place both hands on the steering wheel in the “ten and two” position.
Undo your seat belt.
Break the window. If you aren’t able to open the window, or it only opens halfway, you’ll need to break it with an object or your foot. It may feel counterintuitive (有悖常理的) to let water into the car.
