Appendix:
The content written in this article is the life that Shanghai students are familiar with, but students' understanding of alley life may be different from the author's, so the teaching difficulty is self-evident. Therefore, all three teachers pay attention to guide them to understand the life style of Shanghai alley on the basis of reading the articles written by the author and understanding the characteristics of Shanghai alley. From the very beginning, tian teacher broadcasted "Alley Selling", and at the same time showed photos of Shanghai Alley Style. Vivid and intuitive multimedia intervention enriches students' perceptual knowledge, and they can't help but follow Chen into the alley of Shanghai. In the unfolding teaching of the text, tian teacher has a certain sense of hierarchy. From "Alley"-"Life in Alley"-"Shanghainese in Alley"-"Cultural Characteristics of Alley in Shanghai", students can feel the truest Shanghai and the truest Shanghainese in reading sentences, such as their different behaviors in public places and alleys, and realize that Shanghainese pay attention to both decency and discretion. Meanwhile, tian teacher paid great attention to the repeated "knocking" of keywords such as "neither supercilious nor supercilious". Teacher Chai Weiwei is good at grasping profound paragraphs for students to read and chew carefully. On the basis of reading the full text, he first instructed students to carefully read the words describing the life scene in Shanghai Lane, and read out what it wrote, what techniques were used and how the author's feelings were revealed. This is an important and wonderful passage of the article, and reading it well is the basis for understanding the main idea of the article. Then let the students read and write the characters with Shanghainese temperament in the alley, focusing on the relationship between the people in the alley and the alley in Shanghai. Finally, read the argumentative passage again and understand the profound meaning of "life background" through discussion. Teacher Wang Ping grasped the vivid close-ups and interesting details that can show the life in Shanghai's alleys and started teaching, which truly reproduced the life picture and cultural features of Shanghai's alleys. The on-site teaching atmosphere is active, and the interaction between teachers and students is positive and harmonious.
