Day19.量变到质变

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.

今天是复盘最后一天，明天就要开始学习新的内容了，今天就把之前学的句子挨个儿复习了一下，然后通读了几遍，这次复习感觉比第一次读的要流利很多，很多单词的发音跟着单个句子读还能读的准确一些，但是放在一段句子里就觉得单词发音不是很准确了，我觉得这个问题的根源是练习量不够大，还不能够处处带脑练习，最影响我的是家里面还有事儿，而我却远在千里之外，压力还是蛮大的。

我也就晚上能抽出个一个小时来练习英语，我尽量让自己集中注意力去练习发音，我知道只有努力这样做，以后才有可能不再被周围环境影响到心境。

努力做事，从事件中发现自己的问题，然后去解决问题，这样的实战才能让自己成长得更快。
