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.

今天是自習(xí)的日子，所以打算自己給自己挑錯，還是主要看了下節(jié)奏方面的問題。

This is the VOA Special English Health Report.（批注：時長4s與原音一致，但不包括語調(diào)和發(fā)音）

Cardiopulmonary resuscitation, or CPR, can save the life of someone whose heart has stopped. （第一句結(jié)束時長13s，原音14s，其中CPR原音發(fā)音明確每個字母有一定的停頓我連讀無停頓）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.（到此時長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.（時長38s，原音41s，例如combines原音中ai發(fā)音到位，我的不到位，單詞發(fā)音時長就有所減少）

However, a new Japanese study questions the usefulness of mouth-to-mouth breathing.（時長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.（時長1分14s，原音1分17s，其中magzine，輔音z前后的讀法用漢語拼音的說法為原音為三聲和一聲，我是三聲和四聲降調(diào)）

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.（時長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.（時長1分54s，原音1分59s，其中例如said原音中尾音更平一些，我是降調(diào)）

Twenty-two percent survived with good brain ability. Only ten percent of the victims treated with traditional CPR survived with good brain ability.（時長2分09s，原音2分13s，其中第一句結(jié)束原音有稍微停頓，我是緊接著讀了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.（時長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.（時長2分58s，原音3分02s）

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.（時長3分25s，原音3分26s，我以為此段是我發(fā)音到位，其實是我讀的有點卡，所以和原音時長基本一致了）

感受與評價（Comments）：

1.有點期待明天S老師的上課，自己自習(xí)的有點無頭緒，S老師快快帶我進(jìn)步呀。

2.詳細(xì)對比了自己的錄音與原音的區(qū)別，除了語調(diào)、重音的我覺得問題還是主要在自己的單詞發(fā)音不夠飽滿，導(dǎo)致語速很快，S老師再啟動儀式上說讀的快的同學(xué)是對自己自信，其實不是，我是有些音標(biāo)發(fā)音不飽滿導(dǎo)致自己一帶而過，就讀的嗖嗖的快。

統(tǒng)計累計的練習(xí)小時數(shù)（Hours）：

1小時（對比自己與原音的不同--逐句對比，聽原音，又讀了幾遍并錄音，其中有一遍快到3分35s，請問我是落下一段沒讀么）

第二天打卡！
