### 原材料引用
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.
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 outh-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.

### 感受与评价
以前总觉得自己听力已经到一定水平，说实话有点不屑于听VOA慢速了，但今天迫于作业压力硬着头皮听原音，才发现原音中很多停顿和重音的位置自己并没有读对，一些元音发音也不饱满所以听上去还是有点中式英语；听原音做标记，才发现模仿原音练习后读起来更加流畅，这或许就是模仿的益处吧，希望以后继续加强这方面的练习，坚持完这个课程，给自己加油!
同时也希望在持续力训练营中学习到更多的发音技巧，包括重音、停顿、连读、弱读等。
