教学过程
Video Time
Step I学习理解
活动一:感知与注意
1. Definition of tsunami
Tsunami waves can strike out of nowhere and cause a lot of destruction. Scientists study and track tsunamis in order to warn people and minimise deaths.
2. Formation and effects of tsunamis.
Read the sentences about the formation and effects of tsunamis. Then match each sentence with the correct picture
A .Tectonic plates push together.
B.A series of waves expands in all directions.
C. Whole sections of cities are destroyed
【设计意图】在观看视频之前，通过阅读和看图，了解海啸的定义、形成和造成的影响，为理解视频内容做好铺垫。
StepⅡ应用实践
活动二:分析与判断
Watch and decide whether the statements are true (T) or false (F)
1. There are few warning signs just before a tsunami hits,
2. A tsunami breaks just like an ordinary wave but is bigger.
3. Scientists at the Pacific Tsunami Warning Center monitor the earth's movements 24 hours a day in order to track tsunamis.
【设计意图】通过观看视频，判断视频中关于海啸的警告、海啸造成的损軎等信息，提商语言的使用能力
活动三:内化与应用
Circle the correct word(s) in each sentence.
1. An earhquake occurs when plates below the earth's surface push together/ pull apart.
2. Tsunami waves deep at sea move fast and rise only a few/hundreds of feet.
3. As these killer waves enter shallow waters, their speed is reduced/raised.
4. Most tsunami damage is caused when the waves come in from/move back out to the sea.
【设计意图】在观看视频后，让学生选择恰当的词汇表达海啸相关信息，这是知识内化的过程，也是促进语言使用准确性的过。
SepⅢ迁移创新
活动四: Discussion
Work in pairs. Discuss the questions
1. What have you learnt about tsunamis
2. What kind of help do you think people who have suffered from a tsunami need
设计意图】在观看视频后，讨论自己所学的有关海啸的知识和海啸灾民所需要的帮助，加深对主题意义的理解，培养学生帮助别人的意识
Assessing Your Progress
活动五
1. Circle the correct word in each sentence (SB, P56, Part 1)
2. Read the passage and fill in the blanks with relative pronouns.(SB, P56, Part 2)
【设计意图】第一个活动是在语境中选择恰当的卑词对不同自然灾害进行描述，属于词汇练习。第二个是选恰当的关系代词修饰和限制地震过程的人或事，属于语法练习，总之，这两个活动都体现了词汇和语法在语境中学习的特点
活动六: Reflecting
I, What did you learn about natural disasters in this unit that you did not know before
2. What else do you want to know about natural disaster
3. What did you find the most difficult in this unit
1. What in this unit motivated you most
5. Overall, I thought this unit was:
□ interesting □ useful 口 so-so □ difficult
