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 lifesaving 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. The study was published in the British medical magazine, The Lancet. Doctors in Tokyo led the research. It examined more than four thousand people who had suffered cardiac arrest. In all the cases, witnesses saw the event happen. More than one thousand of the victims received some kind of medical assistance from witnesses. Seven hundred and twelve received CPR. Four hundred and thirty-nine received chest presses only. No mouth-to-mouth rescue breaths were given to them. The researchers say any kind of CPR improved chances of the patient's survival. But, they said those people treated with only chest presses suffered less brain damage. Twenty-two percent survived with good brain ability. Only ten percent of the victims treated with traditional CPR survived with good brain ability. The American Heart Association changed its guidelines for CPR chest presses in two thousand five. It said people should increase the number of chest presses from fifteen to thirty for every two breaths given.
Gordon Ewy is a heart doctor at the University of Arizona College of Medicine in Tucson. He wrote a report that appeared with the study. Doctor Ewy thinks the CPR guidelines should be changed again. He said the heart association should remove rescue breaths from the guidelines.
He argues that more witnesses to cardiac arrests would provide treatment if rescue breaths are not a part of CPR. He says this would save lives. Studies show that many people do not want to perform mouth-to-mouth breathing on a stranger for fear of getting a disease. Cardiac arrest kills more than three hundred thousand people in the United States every year. The American Heart Association says about ninety-five percent of victims die before they get to a medical center.

Facts:
练篇章的三个方法：
1) 同步跟读（shadowing）
难点在于什么时候开口同步
2) 边看边译
3) 听译（听录音同步译中文）
听到介词of.from等要稍顿，等听到后面部分再连同介词前的名词一起做翻译，也可以拆成两个句子说清楚
Comments:
最后一天，为了不虎头蛇尾，坚持做了数次同步跟读。前面的比后面的熟练。单词还是有很多没到位。被自己立的flag打脸了?同频共振，应该首先就要求发音的。我都不敢回头听自己的预习录音。
