Unit 5 The power of nature
（说课稿）
The First Period Reading
Explanation for the outline of teaching design
Firstly, I make the students realize the great power of nature by listing some natural disasters. Then I focus on one of them—volcano eruption to attract their interest. Third, I tell them there is a new but adventurous job—volcanologist. I ask them to read the whole text within 10 minutes and get the main idea and topic of each part. Then I make them read each part carefully to get detailed information of the text. At last I evaluate this result.
Analysis of teaching background
About the teaching content: The title of this unit is the power of nature. The teacher should make the students realize the great power of nature. They should learn how to describe their feelings after experiencing the natural disasters. They should think about the correct attitude and methods to deal with these disasters. And they also need to promote the awareness of protecting themselves.
The reading is the basic and most important part in the unit. It tells the students about the job as a volcanologist. It describes the grand and wonderful scenes of volcano eruption and the mood when seeing it at the 1st time. The reading shows the fun from nature when you get along well with it. The reading also expresses the significance of this job.
About my students: Their vocabulary is small. The ability and skills of reading are not good. Most of them only can recognize some easy words or phrases. They often stop and give up reading if meeting any difficulty. Even if some of them can finish the reading, they usually get confused about the main idea and only know some unimportant information about the reading text.
