Write a 550-word composition for the senior on duty.

Today is Monday, and I came to school early. There are few students in the classroom. I want to read the text when I open the book. At this moment, Teacher Lu came in and said to me, "Yu Jiaxi, come here." I was very uneasy and thought, "I know my homework is not well written. Teacher Lu asked me to erase it and rewrite it?" I followed teacher Lu nervously, but teacher Lu didn't take me to her office. Instead, she took me to the school gate and put the red ribbon in her hand on me. I'm so excited. It turned out that Teacher Lu put me on duty.

I smiled happily. I really want to tell this news to my mother. When I go to school every day, I envy other students standing at the school gate on duty. Besides, it's my sister's turn twice, and neither time.

I stood upright and carefully checked my classmates' red scarf and school badge. Some students didn't bring a red scarf, some students didn't bring a school badge, and some students were funnier. They didn't bring a red scarf and school badge, and they didn't even have a schoolbag. They just held a skipping rope in their hands.

When I got home at noon, my mother came back. I immediately told my mother that I was on duty today, and my mother smiled. My mother asked me to do better in school because all the children on duty are good students.
