To tell you the truth, I really hate those people who talk loudly in the library. In fact, talking loudly in any public place will be annoying, not to mention the library itself needs a quiet atmosphere. So just like this teacher, he shouted abuse in the library and then spoke ill of others. What he did was really disgusting. Besides, as a teacher, he didn't set an example. How can such a character become an example for students and educate them? I think there should be many people who have the same idea as me, which is why I am so angry with this teacher's practice. Next, I'll talk about why you can't talk loudly in the library.
First of all, talking loudly will affect the study of people around you. Most people choose to study in the library because the learning atmosphere here is better, because most people here can consciously abide by the rules and try to avoid making noise, and everyone is studying hard, so the library will become a place for everyone to study. If everyone can talk loudly here like outside, there will be no need for libraries and study rooms, so the main reason why we can't talk loudly here is that it will affect the study of people around us.
Secondly, public places need to pay attention to words and deeds. Libraries are also public places. Personally, I think that as long as you are in public places, you should pay attention to your words and deeds. After all, being outside is different from being at home. Nobody cares what you want to do or say. On the one hand, talking loudly outside will be disliked by people around you, on the other hand, it will also affect others.
