Lesson 20 Gyro word combinations

The vocabulary of the new word "gyro" in Lesson 20 is as follows:

The 20th "Gyro" in the first volume of the fourth-grade Chinese textbook compiled by the Ministry of Education is a reminiscence essay by the children's literature teacher Gao Hongbo. When "I" was a child, I used a small top to defeat a big top, and then shared the inspiration I gained from it - "A person cannot be judged by his appearance, and the sea water cannot be measured."

The text uses "spinning top" as a clue, and the thinking is clear. First, I write about talking about tops and making tops, then I write about making tops and fighting tops, and finally I write about the principles I learned from them.

In addition to using "gyro" as a clue to write the text, this article also arranges a hidden line, that is, "my" mood changes: I want to make a high-quality top (depressed, sad) ----- Learning that someone gave a top (happy) ---- getting a top (extremely happy) ---- being laughed at (embarrassed) ---- fighting the top successfully (joy, pride). The author uses this series of emotional changes to run through the entire text.

Make the article an organic whole.

By studying this lesson, we will continue to consolidate the method of "reading with comments". The text is also equipped with a comment column, giving children enough space to make comments, thereby further helping children to "learn the method in comments".
