阅读理解。

     Only a small number of office workers have been trained in basic life-saving techniques.

     Just 33,526 of London's estimated 3.5 million workers signed up with St John's Ambulance and the British

Red Cross to learn simple first aid last year. The figures coming from a new report show that nine out of 10

people would not know what to do if a colleague was badly hurt, while 72 percent have never attended a

first-aid course.

     Doctors describe the situation as appalling and have called for urgent training in schools and the workplace.

     Training in first aid should start at an early age and should be taught to everybody at school. First aid is very

important because at best it can save lives and at worst it reduces pressure on hospital rooms. Employers get

anxious when a worker has had some sort of accident in the office or factory and rush them to the

hospital-even if all they require is a bandage.

     Last year 20,000 Londoners were trained in first aid by St John's Ambulance, the leading provider in

life-saving courses, and 13,526 were trained by the Red Cross. According to St John's Ambulance, four out of

five parents do not know how to carry out mouth-to-mouth resuscitation (苏醒).

     Nick Suggitt, training manager with St John Ambulance, said,"We are training just a tiny part of the number

necessary, and only touching the tip of the iceberg."

     "Not enough people know how to save a life, and since many emergencies occur at home or at work, these

skills are often needed to save the life of a friend or a family member."
