In senior three, we went to Chang 'an An Wei No.1 Middle School as an intern. My practice instructor is Li Weining from No.1 Middle School. He is a respected and experienced teaching and research leader and a senior history teacher. We admire his thorough and clear explanation, flexible mobilization and profound historical knowledge. Maybe it's because I've been an athlete since I was a child, and I have a kind of momentum and a spirit of hard work in everything I do. From observing the teacher in class to preparing lessons and writing lesson plans by myself, I am serious and meticulous. It's time for class. I stood outside the classroom of Class 12, Senior High School, waiting for the second bell to ring. Suddenly, I was so nervous that I trembled all over. I crustily skin of head walked into the classroom. I tried to squeeze out a smile from my stiff face, put on a calm posture and said "Ben" to the class as loudly as possible. At the same time, my face is red and I feel that I am working at a low salary. The students responded in unison: "Hello, teacher!" . Seeing the clear and frank eyes of my classmates, I suddenly became calm, natural and close. After returning the gift, I already feel like a teacher. I finished the first class in my life with generosity and confidence, and I was in a state of excitement for a long time after class, communicating with students in depth, exchanging spiritual feelings with classmates, and constantly chewing the sacredness and pride of being a teacher. "He is the seed of a good teacher." Teacher Li commented on me as the leader of our department and gave me a rare "excellent" internship performance. It is such encouragement that I found my life coordinates and my favorite job. When I graduated from college as a teacher, I turned helplessness into yearning and expectation.
