questions. (Based on the whole text)

1 Why should you put cold water on a burn?

2 Why doesn't a third degree burn hurt?

Step 5 Group Discussion

Please decide whether the following treatments of first aid are right or wrong. If it is wrong, please point out the mistakes.

1. Sam knocked over a kettle full of boiling water onto his legs. His legs became red, swollen and covered with blisters. Sam broke the blisters and poured icy water from the fridge onto the skin. Key:

?Sam shouldn't have broken the blisters because the burns could become infected.

?Sam shouldn't have poured icy water but cool water on the burn.

2.Mrs. Casey’s sleeve caught fire while she was cooking. Her arm looked terrible but it didn't hurt. The skin was charred. Her husband took off her blouse and picked off bits of the blouse stuck to the burn. He then placed butter on the burn and covered it with a wet bandage.

Key:

?He shouldn't have picked off bits of blouse off the burn. Because if you pull the clothes that are stuck to the burn, you would pull the tissue under clothes off too. This would cause more damage to the burn.

?He shouldn't have placed butter on the burn because it would prevent the heat from escaping and cause infection.

Mark’s left foot gets burn ed by a cracker(鞭炮) with his trousers on. His left foot is red, swollen and covered with blisters. He feels very painful, especially when he walks.

●Discuss: 1) Which type of burns it belongs to? 2) What kind of treatment should you give to

him? (Try to apply the knowledge of first aid for burns that you have learned today.)

●Then act out the process of treatment step by step in front of the whole class.

教学反思

本节课的教学设计主要围绕“First Aid for Burns”这篇文章展开阅读教学。文章是一篇关于烧伤急救知识的说明文，各小节结构分明，内容相对简单，细节信息点较多，因此阅读任务的设置主要体现在学生阅读速度、掌握大意、细节理解和根据所学信息进行判断的这些方面上，通过完成精心编排的思维导图和导学案，培养和提高学生的阅读能力，以读促说，学以致用，把急救知识运用到口语活动中。

首先，引入部分通过学生拍摄的视频和急救知识小测试导入到文章主题，能够激发学生学习急救知识的兴趣。阅读过程中，阅读任务由易到难，环节紧凑，课堂效率高，学生自主探究学习的兴趣较浓，小组讨论气氛活跃。小组活动的设计与生活实际联系密切有关，以小组合作学习的形式，提高学生的课堂参与度，创设情境让学生开口说英语和动手解决问题。通过这节课，学生进一步掌握了一些正确的急救知识，培养了学生临危不乱和助人为乐的精神。教学目标基本实现，课堂效果较为满意。课后巩固作业的布置延伸了课内所学，也为下一课时的教学做好了铺垫。总体来讲，教学的各个环节都得到了很好的落实。

不足之处在于，部分学生课前预习不够充分，对课文相关词汇和话题不够熟悉，影响了课堂学习进度。部分学生的小组活动参与积极性不够高，可合理进行分组，让英语成绩较好的学生带动后进生的学习热情。
