"Octagonal Tower" tells the story of Chairman Mao's hard and intense work day and night in a difficult environment, and has written many brilliant works, showing his selfless dedication to leading the China revolution.

The full text is plain and narrated in the form of stories. The text is illustrated. Combining the language elements of this unit "Understanding the text with words" and two exercises after class, it is clear that "Understanding the meaning of words with illustrations, feeling the hardship of the environment and Chairman Mao's selfless work, and grasping the key words to talk about how Chairman Mao works" is the focus of this lesson.

In addition, because the story of the revolutionary era is far away from students' lives, it is difficult for students to understand, which is a reading difficulty for students. In teaching, students can use pictures, videos and other materials to help them intuitively build pictures. Secondly, the unified textbook advocates the cultivation of students' retelling ability. Teachers can use illustrations, pictures and words to extract keywords to pave the way for students to retell, and practice retelling stories together at the same table.
