衛生類復習指導：補全短文Chest Compressions
Cardiopulmonary resuscitation， or CPR， can save the life of someone whose heart has stopped. The condition is called cardiac arresta. 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 victims mouth and repeated presses on the chest._______.
However， a new Japanese study questions the usefulness of mouth-to-mouth breathing. The study was published in the British medical magazine， The I， ancet3. 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______The researchers say any kind of CPR improved chances of the patients survival. But， they said those people treated with only chest presses suffered less brain damage. Twenty-two percent survived with good brain ability _______.
The American Heart Association4 changed its guidelines for CPR chest presses in 2005.
______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______.
Cardiac arrest kills more than 300，000 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.

練習：
A So far， we have not known exactly yet whether mouth-to-mouth breathing is really useless in CPR.
B Only ten percent of the victims treated with traditional CPR survived with good brain ability.
C CPR keeps blood and oxygen flowing to the heart and brain.
D His studies show that many people do not want to perform mouth-to-mouth breathing on a stranger for fear of getting a disease.
E It said people should increase the number of chest presses from fifteen to thirty for every two breaths given.
F No mouth-to-mouth rescue breaths were given to them.
答案與題解：
1 C 本空白處的前一句是介紹CPR是什么，而六個選項中，C項也是介紹CPR的，因此放在一起是恰當的。
2 F 本空白處的前一句說“439位病人僅僅接受了胸腔按壓”，而第一段說過，“CPR包括胸部按壓和白對口呼吸”，可見F項說“沒做口對口呼吸的急救措施”是補充說明前一句的。
3 B 本空白處的前面兩句說到，只用胸部按壓搶救過來的人大腦受損比較小，存活下來的人中有22％大腦功能良好，接下來這一句肯定是要與傳統的兩種方法結合的搶救模式作對比，選項B正好是這樣的內容。
4 E 本空白處的前一句是說美國心臟協會于2005年修改了CPR中胸部按壓的指導準則，空白處的后面又沒有提到如何修改，選項E正好填補了這個內容。而且還要注意，選項E中的It said只能適用于American Heart Association，其他空白處均不合適。
5 D 這一段都是敘述心臟疾病醫生Gordon Ewy的觀點，在其他地方都沒有提到他，因此選項D His studies show…實際上已經為我們提供了答題的線索，內容也能前后銜接。
