Inadvertently, I passed a classroom after class and saw a teacher in his 500 s. He was alone in the empty classroom, struggling to wipe the blackboard, surrounded by tiny white powder flying around, but he didn't care, he wiped it anyway ... In a short time, his head, clothes and even eyebrows were covered with dust. After wiping, he put the blackboard eraser back on the platform and wiped the platform again. Only then did I slowly walk out of the classroom with my textbook and lock the door myself. Seeing me standing at the door, he paused for a moment, and then smiled at me. I wanted to say something to him, but my face turned red and I couldn't say anything. I can only watch him gradually disappear from my sight. This sudden scene can't help but make my thoughts soar ... this is a very strange phenomenon I found in college, and it also makes me feel very chilling. I don't understand, I once doubted, but I am more confused. I can't help asking myself: What is the teacher-student relationship now? Is it as harmonious on the surface as we thought? As the saying goes: "One day as a teacher, life as a father." This sentence is deeply rooted in our bones, and we always remember it in primary school, junior high school and senior high school. But in college? Can we abandon it in the university? Can we say that teachers in universities can fall to the ground or step on their feet? I really feel sad and sad for what some of us have done. Teachers are the ladder of human progress, and parents who guide our life path and give us knowledge. But? However, in universities, teachers are forced to change roles. The teacher must clean the blackboard for his students after school, and lock the door after the students leave. Isn't that enough? Do we have to be happy when the teacher sweeps the floor for us? If the teacher does all this for us, what should we students do? Do we just sit in the classroom and listen to the teacher? Then, after class, I patted my ass and left the classroom. I didn't clean the blackboard or sweep the floor. I left all these jobs that I thought were dirty and tiring to the teacher. Is that all? I really doubt what happened to one of us. Don't they really know that respecting teachers is important? Don't they know that it is the duty of students to clean the blackboard? No, they know. They just don't want to do it. Thus, a very serious topic is exposed in front of us-the quality of college students. Now some people think they are college students, so they are great, superior to others, and even superior to teachers. Isn't this very humble and shallow? How can such a college student be a qualified college student? What can they do at school? I'm afraid it's not surprising to skip class and surf the internet! Isn't it a waste of life to treat these things as research topics for four years of college life? Isn't this a waste of youth? How can you expect a person who doesn't even respect his teacher to achieve greater success? I'm afraid these people are just scum and moths when they enter the society. Remember the college student who hit and stabbed people in Shaanxi? Remember that Hebei college student who said "My father is Li Gang"? Aren't they all highly educated? However, they have done such heinous things. Shouldn't college students like them be condemned by society? Can the bright future of the motherland be handed over to college students like them? You may be surprised: since you are highly educated, you should be a virtuous person, but … yes! Hey! Don't understand! It is said that the world is going from bad to worse, and I am afraid it is not groundless. Isn't all this showing us the disharmony of this society? Can't help but make us ponder! It is undeniable that this society has an abnormal development side, which is a fact! Maybe our society is really helpless, maybe some of us are really miserable, but it's not that society has changed, but that people's hearts have changed, becoming more and more unpredictable and terrible. But I really don't want some of our college students to sink, otherwise, how can we shoulder the heavy responsibility entrusted to us by our motherland? It's time for us to deeply analyze ourselves and reflect on ourselves, and it's time to improve our quality, because this society needs not only people with knowledge, but also people with noble character. What a kind word a teacher is and what an admirable position a teacher is. We should respect teachers, understand teachers, let them give us less snacks, let them have a rest, and let them stop cleaning the blackboard for us! I hope some of our college students put their positions right. Of course, including me, we should always remember not only to listen to the teacher carefully, but also to help them clean the blackboard after the teacher has finished speaking. Although this is a very small thing, you may not feel anything, but the teacher will feel very gratified. Really, don't believe it. Look at the smile on the teacher's mouth, which is the best proof! Some people say that teachers are not only teaching us knowledge, but also teaching us how to be human. This statement is true and alarming! When I pass by that classroom in the future, I always habitually look inside, and I feel as if I saw the teacher in his 500 s again. A person was in an empty classroom, struggling to wipe the blackboard, and the dust all over the sky filled him, but he didn't care at all, just rubbed it ... At this moment, I seemed to see another student, ran to him quickly and said to him, "Teacher, you have a rest." With that, he grabbed the eraser from his hand and wiped it. I looked at the old teacher and all the wrinkles on my face were scattered. A drop of tears, smacked, fell to the ground and broke into a happy petal!
