The Teaching Plan for the Violence of Nature
一．整体设计思路：
本节课的教学内容为本模块的阅读篇章，该篇文章属于说明文，其主题为龙卷风和飓风的介绍。我结合教材对篇章进行适当的增补，让学生了解龙卷风和飓风来临时的一些应对措施，并对此篇章进行了深度阅读。 二．教学目标
Students are expected to be able to
1. Learn about what is a tornado and what is a hurricane;
2. Know about how to protect themselves when a tornado and hurricane occur; 3. Learn how to collect and deal with information they need through team work; 4. Learn how to analyze the structure of exposition
5. Realize the importance of protecting themselves when natural disasters occur. 三．教学重难点
1. How to get the key information and summarize it; 2. How to express their suggestions
四．教学过程 Step1:Lead-in
Watch a short video and answer the questions: What happened in this area? What was the family doing?
How about the trees and houses?
设计意图：通过视频，引出话题，让学生感知龙卷风的巨大破坏性以及观察到龙卷风来临时人们的应对措施，为后面的讨论作铺垫。 Step2:Reading
1. Read what is a tornado and underline the supporting sentences for the questions: What is a tornado? How strong are the tornado winds? Where does it often occur?
What damages are caused? How many tornadoes are there in US each year? What happened in 1925? What were the results?
设计意图：学生在老师的问题引导下迅速抓到文章的主要信息。 2. The teacher draw the mind map depending on students’ answers; 设计意图：老师示范怎么梳理信息。
3. Read what is a hurricane and draw a mind map by students themselves; 设计意图：学生通过校长活动学会自己收集和梳理信息。 4. Share what is a hurricane based on the mind map they draw;
设计意图：学生通过阅读输入了信息，再有条理地输出信息。 5. Reflect on the passage:
Decide whether the following sentences are describing tornadoes or hurricanes. 1). It moves heavy things to different places. 2). It causes huge wave. 3). It occurs in the oceans. 4). It takes off the fur of a cat.
5). It affects the east coast of the US.
6). It destroys houses without damaging the furniture.
2
7). It occurs 800 times each year.
8). It occurs 6 times each year in Atlantic.
设计意图：检测学生是否已掌握所获取的信息。
6. Read an extraordinary event and put the following sentences in the right order: a. The coffin was found in the sea near his hometown. b. Coghlan moved to New York.
c. Coghlan died in Galveston and was buried there. d. The cemetery was destroyed.
e. Charles Coghlan went to live in Canada. f. Coghlan moved to Galveston . g. Hurricane occurred.
h. The coffin ended up in the sea. i. Coghlan travelled back to Canada.
7.Thinking: Why does the author mention the story at the end of the passage? 设计意图：通过排序，读懂故事；通过问题，让学生关注并思考文章的结构。 Step3:Discuss in groups:What should we do before and when natural disasters occur?
设计意图：自然灾害随时发生在我们身边，通过讨论，让学生了解龙卷风和飓风来临时我们的应对措施。
Step4:Summary and assignment
设计意图：通过总结，让学生在灾难来临前有预防意识，在灾害来临时有保护意识。 五．板书设计：
