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.

This is the VOA Special English Health Report.（批注：时长4s与原音一致，但不包括语调和发音）
Cardiopulmonary resuscitation, or CPR, can save the life of someone whose heart has stopped. （第一句结束时长13s，原音14s，其中CPR原音发音明确每个字母有一定的停顿我连读无停顿）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.（到此时长30s，原音32s）
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.（时长38s，原音41s，例如combines原音中ai发音到位，我的不到位，单词发音时长就有所减少）
However, a new Japanese study questions the usefulness of mouth-to-mouth breathing.（时长44s，原音48s）
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.（时长1分14s，原音1分17s，其中magzine，辅音z前后的读法用汉语拼音的说法为原音为三声和一声，我是三声和四声降调）
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.（时长1分38s，原音1分42m）
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.（时长1分54s，原音1分59s，其中例如said原音中尾音更平一些，我是降调）
Twenty-two percent survived with good brain ability. Only ten percent of the victims treated with traditional CPR survived with good brain ability.（时长2分09s，原音2分13s，其中第一句结束原音有稍微停顿，我是紧接着读了only）
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.（时长2分29s，原音2分35s）
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.（时长2分58s，原音3分02s）

Studies show that many people do not want to perform mouth-to-mouth breathing on a stranger for fear of getting a disease.（时长3分25s，原音3分26s，我以为此段是我发音到位，其实是我读的有点卡，所以和原音时长基本一致了）

感受与评价（Comments）：
1.有点期待明天S老师的上课，自己自习的有点无头绪，S老师快快带我进步呀。
2.详细对比了自己的录音与原音的区别，除了语调、重音的我觉得问题还是主要在自己的单词发音不够饱满，导致语速很快，S老师再启动仪式上说读的快的同学是对自己自信，其实不是，我是有些音标发音不饱满导致自己一带而过，就读的嗖嗖的快。
统计累计的练习小时数（Hours）：
1小时（对比自己与原音的不同--逐句对比，听原音，又读了几遍并录音，其中有一遍快到3分35s，请问我是落下一段没读么）
第二天打卡！
