This is the VOA Special English Health
Report.
Cardiopulmonary resuscitation, or CPR, can save the life of someone whose heart has stopped. The condition is called cardiac arrest. The heart stops pumping blood. The person stops breathing. Without life saving measures, the brain starts to die within four to six minutes.
CPR combines breathing into the victim's mouth and repeated presses on the chest.
CPR keeps blood and oxygen flowing to the heart and brain.
However, a new Japanese study questions the usefulness of mouth-to-mouth breathing.Thestudy was published in the British medical magazine, The Lancet.
Doctors in Tokyo led the research.It examined more than 4000 people who had suffered cardiac arrest.
In all the cases, witnesses saw the event happen. More than 1000 of the victims received some kind of medical assistance from the witnesses. Seven hundred and twelve received CPR. Four hundred and thirty-nine received chest presses only.

复习音标跟读，/l//o//r/，越来越感觉/r/的音没那么难没那么别扭了，哈哈，可hundred还是有些跟听到的不太一样，另外only的舌头有些乱了，明天再多练习应该会好吧。
