Homework:(A)British Red Cross volunteer Philip Roberts showed how important basic first aid skills can be by saving a road crash victims life.Philip was driving down the M6 motorway

7、 early one morning when he came across a serious road accident. A truck had crashed into a car， driving it off the motorway and into a roadside bank.As the first person on the scene， Philip made sure it was safe to approach the vehicle and found an unconscious woman inside， slumped（陷入）forward and wi

8、th her airway blocked. As another driver approached， he shouted for them to call the emergency services. Then Philip acted fast.He recalls： Climbing into the car， I immediately lifted the womans head and opened her airway， so she would be able to breathe. I then kept my hands on her head to keep her

9、 neck steady， as the crash could have caused spinal（脊柱的）injury.When the emergency services arrived， they asked me to stay inside the car and maintain（维持）the womans airway while they cut off the roof of the car. By the time the woman was freed from the vehicle， half an hour later， she was starting to

10、 regain consciousness（意识）。Philip said， The simple first aid techniques I used can be learned in five minutes， yet they probably saved the drivers life.

15、rmed by a lay person to a sick or injured patient until definitive medical treatment can be accessed. Certain self-limiting illnesses or minor injuries may not require further medical care. It generally consists of series of simple life-saving techniques that an individual can be trained to perform

16、with minimal equipment.While first aid can also be performed on animals，the term generally refers to care of human patients.Certain skills are considered essential to the action of first aid and are taught everywhere. Particularly，the “ABC”s of first aid，which focus on critical life-saving action，mu

Attention must first be brought to the airway to ensure it is clear. Choking is a life-threatening emergency. A first aid attend
