Her seriousness is really surprising. One morning, the math teacher handed out a test paper and said that there would be a test on the spot. When I finished the paper, I found that she was meticulously and carefully checking whether anyone was present. I called her, but she didn't hear me. She has been checking. I called her several times in a row, but she still looked serious and ignored me at all.
She is not only serious, but also responsible. On one occasion, the teacher asked her to check the red scarf and school badge, and check it every morning and report to her. From that day on, whenever a classmate came into the classroom, she ran to check whether that classmate came in with a red scarf and school badge. If not, she takes notes and reports to the teacher.
Yang Xin is an example for me to learn from. I want to learn her advantages and turn them into my own.
