文本来源：人教版必修五第五单元读写 “烧伤的急救”

文章体裁：说明文

主要内容：这是来自急救知识参考书里的一篇文章。介绍了烧伤的原因，类型，特征以及不同烧伤程度的处理。

在该课中，方老师的处理是这样的：

由于本文框架结构清晰，方老师首先让学生自主梳理主要的框架结构。迅速理清本文的主要内容。然后分不同的part进行细读，最后根据开头的框架对整篇文章进行内容总结。

设计思路：

1.点明急救的定义，并匹配一组关于急救的问题小测验，强调急救是临时的救助方式当遇到重病时还是得马上打120等待医生的专业救援。附带赠送心脏复苏小知识。

2.快速浏览课文，自行梳理框架标题和小标题，找出本章的中心和主要内容。

3.强调皮肤的重要性。用因果逻辑对第一段落进行解读。并重点说明段落中总分的行文方式。Essential 和complex分别由各自的支撑细节信息，配以皮肤层次图进行说明。

4.烧伤的原因，类型和特征相对比较简单，可由学生自己细读文章，以最快的速度回答所列的问题和表格。

5.重点处理烧伤的急救处理方法和步骤。改变日常生活里错误的观念。让学生思考，为什么最后部分以数字为段落并以祈使句为开头。整篇阅读结束后，反思本文的类型：是一篇来自家庭急救工具书的文章，所以框架结构非常清晰方便读者快速找到所需信息。

6. 最后，方老师根据文本特点进行了概要写作微技能的训练，并提供了参考范文。

另：方老师还提供了一个现场演示烧伤急救的小视频，很应景。赞！

----JOHN SNOW DEFEATS “KING CHOLERA”

John Snow was a famous doctor in London-so expert, indeed, that he attended Queen Victoria as her personal physician. But he became inspired when he thought about helping ordinary people exposed to cholera. This was the deadly disease of its day. Neither its cause nor its cure was understood. So many thousands of terrified people died every time there was an outbreak. John Snow wanted to face the challenge and solve this problem. He knew that cholera would never be controlled until its cause was found.

He became interested in two theories that possibly explained how cholera killed people. The first suggested that cholera multiplied in the air. A cloud of dangerous gas floated around until it found its victims. The second suggested that 6people absorbed this disease into their bodies with their meals. From the stomach the disease quickly attacked the body and soon the affected person died.

John Snow suspected that the second theory was correct but he needed evidence. So when another outbreak hit London in 1854, he was ready to begin his enquiry. As the disease spread quickly through poor neighbourhoods, he began to gather information. In two particular streets, the cholera outbreak was so severe that more than 500 people died in ten days. He was determined to find out why.

First he marked on a map the exact places where all the dead people had lived. This gave him a valuable clue about the cause of the disease. Many of the deaths were near the water pump in Broad Street(especially numbers 16,37,38 and 40). He also noticed that some houses (such as 20 and 21 Broad Street and 8 and 9 Cambridge Street) had had no deaths. He and not foreseen this, so he made further investigations. He discovered that these people worked in the pub at 7 Cambridge Street. They had been given free beer and so had not drunk the water from the pump. It seemed that the water was to blame.

Next, John Snow looked into the source of the water for these two streets. He found that it came from the river polluted by the dirty water from London. He immediately told the astonished people in Broad Street to remove the handle from the pump so that it could not be used. Soon afterwards the disease slowed down. He had shown that cholera was spread by germs and not in a cloud of gas.

In another part of London, he found supporting evidence from two other deaths that were linked to the Broad Street outbreak. A woman, who had moved away from Broad Street, liked the water from the pump so much that she had it delivered to her house every day. Both she and her daughter died of cholera after drinking the water. With this extra evidence John Snow was able to announce with certainty that polluted water carried the virus.

To prevent this from happening again, John Snow suggested that the source of all the water supplies be examined. The water companies were instructed not to expose people to polluted water any more. Finally “King Cholera” was defeated.
